A well-functioning property tax system could offer many benefits to the nations of sub-Saharan Africa. At a time of decentralization, when local governments are being asked to assume new responsibilities for services and infrastructure in such countries as Sierra Leone, South Africa, and Uganda, a dependable and locally administered source of revenue would greatly benefit local democracy and economic development. It could improve the standard of living in local communities on a continent still grappling with abject poverty and poor governance.

Faculty Profile, John H. Bowman

Cities are both contributors to and victims of global climate change. Delta cities, in particular, have long been recognized as being extremely vulnerable because they are located where the stresses on natural systems coincide with intense human activity.

A number of climate change impacts may affect delta cities, including rising sea levels, infrastructure damage from extreme weather events, the public health implications of higher average temperatures, altered energy consumption patterns, stress on water resources, impacts on tourism and cultural heritage, decreased urban biodiversity, and ancillary effects on air pollution (IPCC 2007). Climate change also may affect physical assets used for economic production and services, as well as the costs of raw materials and inputs, which in turn will affect competitiveness, economic performance, and employment patterns.

China’s remarkable economic growth since the beginning of the country’s reform period in 1978 has concentrated a large share of population and wealth along the coast, especially in three megacity regions: Pearl River Delta, Yangtze River Delta, and Capital Region. While the potential implications of climate change pose a challenge for coastal communities around the world, this geographic concentration of population and economic activity seems disproportionate in China.

Among China’s coastal and delta regions, the Pearl River Delta (PRD) in Guangdong province is an important economic center that includes the cities of Guangzhou, Shenzhen, and seven prefecture-level municipalities. Together with Hong Kong and Macao, the greater PRD area is one of the key megacity regions in the world, but its geography makes it highly vulnerable to sea level rise. Unprecedented economic and urban development, along with the major changes in land use and land cover accompanying that development over the past three decades, has released large emissions of CO₂, leading to higher temperatures and more intensive and extreme weather events (Tracy, Trumbull, and Loh 2006). Given the importance of this region to both China and the broader global economy, we take a closer look at the PRD’s contribution to and risks from climate change.

Industrialization and Urbanization

With the establishment of the Shenzhen and Zhuhai Special Economic Zone in 1980, the PRD was among the earliest regions in China to begin to liberalize its economy. Its institutional advantages, combined with its proximity to Hong Kong and Macao, made the PRD the fastest growing region in the world during the past three decades. From 1979 to 2008, the PRD’s GDP grew at 15.6 percent annually in constant prices, outpacing both the national rate of 9.77 percent and the provincial rate of 13.8 percent.

As a result, the delta’s contribution to the share of GDP in China soared from 2.8 percent in 1979 to 9.5 percent in 2008. In terms of total fixed investment, foreign direct investment, exports, and energy consumption, the PRD was one of the most important and dynamic economic regions in China during this period (figure 1).

This rapid development resulted from the dual process of industrialization and urbanization. The region’s secondary and tertiary industries have grown rapidly as primary industry has gradually decreased in relative economic importance, with its contribution to GDP declining from 26.9 percent in 1979 to 2.4 percent in 2008, while the tertiary service sector grew from 27.9 percent to 47.3 percent.

Over the same time, the population increased from 17.97 to 47.71 million residents, reaching an urbanization rate of 82.2 percent in 2008. In terms of land use, areas designated for manufacturing, residential, and commercial uses grew by 8.47 percent annually, increasing from 1,068.7 square kilometers (k2) in 1979 to 4,617.16 k2 in 2008 (figure 2).

Climate Changes

Given these dramatic land use changes and the region’s increased emissions of greenhouse gases, it is not surprising that the PRD has experienced noticeable regional climate changes. The Guangdong Meteorological Administration (2007) reported that the average temperature increase in Guangdong province over the past five decades has been 0.21 °C every 10 years, which is similar to the rate of warming seen nationally in China. Guangdong’s coastal region, especially the highly urbanized PRD, witnessed even greater temperature increases, averaging 0.3 °C every 10 years. The cities of Shenzhen, Dongguan, Zhongshan, and Foshan warmed more than 0.4 °C every 10 years.

After compiling data from 21 meteorological stations in the PRD region, we calculated the average annual and seasonal temperatures during the 1971–2008 period and compared them with the annual temperatures in Guangdong. Our research showed the PRD has experienced significant warming and has been hotter than the entire Guangdong province during the observed period. Since the 1970s, the PRD has seen its average temperature rise by approximately 1.19 °C to 22.89 °C in the most recent decade, with annual average temperatures remaining above the region’s 30-year average temperature of 22.1 °C since 1994 (figure 3).

The winter and autumn seasons saw the most considerable temperature increases, with averages of 24.1 °C in the autumn and 15.2 °C in the winter between 1994 and 2007. These temperatures are significantly higher than their respective 40-year averages of 23.5 °C and 14.6 °C. While not as significant, average spring and summer temperatures in the PRD during the 1997–2007 period were also greater than their 40-year average temperatures of 22 °C and 28.2 °C. This regional warming phenomenon is also seen to a lesser degree in Guangzhou, a populous and characteristic metropolis in the PRD, where average temperatures have risen like those in the greater delta region.

As the PRD’s climate has warmed more quickly than that in the rest of the province, the rapid industrialization and urbanization has generated enormous energy demand from manufacturing industries, transportation, and residential consumers, resulting in greater emissions of CO₂ and other greenhouse gases that are contributing to global climate change. The increased concentration of greenhouse gases, both regionally and globally, represents a large latent source of future warming and additional changes.

Impacts of Climate Change

Given its coastal geography and population density, Guangdong is among the most vulnerable of China’s coastal provinces to the sort of meteorological disasters that are expected to increase with global warming. In 2008, Guangdong experienced direct economic losses of 15.43 billion yuan and 73 deaths, accounting for 75 percent and 48 percent of national totals, respectively, as well as the loss of 602 kilometers (km) of land to coastal erosion (table 1). With sea levels in the province having risen by 75 millimeters (mm) during the 1975–1993 period, the China Meteorological Administration’s (2009b) prediction that sea levels will rise a further 78–150 mm between 2008 and 2038 represents a serious threat to coastal infrastructure and communities in the PRD.

Guangdong has long been impacted by marine hazards such as rainstorms, cyclones, and storm surges that have killed hundreds of people, caused serious damage to housing and transportation infrastructure, and impacted farming in the province. In the 1950s, the annual average farming area affected by marine hazards was about 200,000 hectares (ha), which grew to 440,000 ha in the 1960s and 500,000 ha in the 1970s, before jumping to 1,411,000 ha in the 1990s.

In addition to more frequent extreme storm events, instances of drought also have been increasing in the PRD. In the 1950s, the average farming area affected by droughts in Guangdong was 104,000 ha, which grew steadily to reach 201,500 ha in the 1980s, 282,500 ha in the 1990s, and 426,400 ha in the 2000s. Given the expected increases in the frequency of extreme weather events, as well as rising temperatures and sea levels, agricultural and mariculture activities in the PRD will be increasingly vulnerable to future climate change.

Cities in the PRD are particularly susceptible to natural disasters and climate change as they concentrate infrastructure, nonagricultural activities, and population, severely impacting economic activities and daily life. Rainstorms and typhoons occur frequently in the region and typically entail serious damage and huge economic losses. During the 2000–2007 period, for instance, rainstorms and typhoons in Shenzhen caused cumulative direct economic losses of 525 and 277 million yuan respectively, accounting for approximately for 63 and 33 percent of total direct economic losses associated with all meteorological hazards in the city (figure 4).

Meteorological hazards also lead to disruptive impacts on facilities, infrastructure, and transportation. Rainstorms and typhoons impose challenges on urban sewage systems and flood control facilities, while prolonged periods of high or low temperatures exert pressure on urban power supply infrastructure.

In May 2009, Shenzhen experienced an unprecedented rainstorm, with some parts of the city receiving daily precipitation in excess of 208 mm. The storm flooded 40 areas of the city and left 11 areas under at least one meter of water. Two years before, in April 2007, rainstorms flooded the Qinghuhe River in Shenzhen, damaging embankments and toppling power lines. On the other end of the spectrum, in July 2004 Guangzhou suffered a prolonged heat wave that created tremendous demand for electricity. Usage eventually peaked at 8.45 million kilowatts and forced many enterprises to stop production to help conserve power.

Transportation is the lifeline of urban activity and economic production. As two of China’s major population and economic centers, Shenzhen and Guangzhou are particularly important national transportation hubs, and any disruptions from extreme weather events such as rainstorms, typhoons, and flooding have far-reaching effects across the country.

When tropical storm Fengshen landed in Shenzhen on June 24, 2008, the city’s Yantian seaport was forced to close and hundreds of vessels were stuck in port, resulting in huge economic losses. During 2008, four tropical storms and one rainstorm resulted in the cancellation of 249 flights and the delay of 386 other flights at the Shenzhen International Airport, stranding more than 20,000 passengers. In 2009, three major weather events caused the cancellation of 176 flights and the delay of 326 flights, while 4,151 ships were forced to take shelter in Yantian port. As Chinese travelers become more affluent and air travel grows more rapidly, the vulnerability of these cities to disruption by severe weather events is set to increase.

Disruptive Effects of Sea Level Rise

The China Meteorological Administration (2009b) has identified the PRD as one of the country’s areas most at risk from rising sea levels due to its low mean sea level. Previous studies concur that sea levels in the PRD are rising and will continue to do so in the foreseeable future. Figure 5 illustrates the changes in sea level recorded at three tidal gauges (Hong Kong, Zha Po, and Shan Tou) during the 1958–2001 period. Hong Kong recorded a sea level rise of 0.24 centimeters per year (cm/year) during the period, while Zha Po and Shan Tou saw sea levels rise by 0.21cm/year and 0.13cm/year, respectively. Tidal records from six different gauges in the Pearl River estuary show that sea levels have risen at an accelerating rate over the last 40 years.

With the melting of glaciers globally due to climate change, these recent rises in sea level are expected to continue and potentially even accelerate. Li and Zeng (1998) offered three forecasts for sea level rise in the PRD, with 100 cm (high), 65 cm (middle), and 35 cm (low) forecasts by 2100. These predictions have been echoed by similar projections from the Chinese Academy of Sciences (1994), which indicate that sea levels in the PRD would rise by 40 to 60 cm by 2050.

The physical geography and urban development of the delta render it extremely vulnerable to the effects of sea level rise, and many lowland areas are likely to be inundated (Yang 1996). According to calculations by China’s National Marine Data and Information Service, a sea level rise of 30 cm could inundate an area of 1,154 k2 of coast and islands at high tide, with Guangzhou, Doumen County, and Foshan at particular risk (Guangdong Meteorological Administration 2007).

Coastal and river flooding in the PRD is influenced by several factors: rainfall, high tides, high winds, and typhoons and storm surges. The combination of weather and tidal factors that causes water levels to rise by upwards of three meters during tidal cycles is already well known in parts of the Pearl River Estuary (Tracy, Trumbull, and Loh 2006). According to Huang, Zong, and Zhang (2004), the current maximum tidal range increases as one travels up the estuary, from a low of 2.34 meters near Hong Kong to 3.31 meters at Zhewan, before reaching 3.35 meters at Nansha.

Rising sea levels would magnify the effect of storm surges, which already can be dramatic when weather and tidal factors coincide. Analyzing records from 54 tidal gauges across the PRD, Huang, Zong, and Zhang (2004) created predictions for water level rises in different parts of the delta under a number of different flood scenarios. According to the lowest freshwater discharge scenario (2000 m2/s), their simulations show that a 30 cm sea level rise will affect the northwest part of the region most severely and the majority of the area significantly. These researchers also simulated the impacts of a 30 cm sea level rise on the distribution of flood damage based on four freshwater discharge scenarios, showing that as floods increase in severity the size of the areas affected also increases.

Summary and Discussion

Delta cities enjoy locational advantages that make them attractive to both residents and businesses, and thereby lead many delta regions to develop into vital economic cores in many countries. Delta cities, however, are particularly vulnerable to meteorological hazards and are more at risk than inland cities to the existing and anticipated effects of climate change. The Pearl River Delta has witnessed substantial increases in both sea levels and temperatures, greater variation in rainfall, more frequent extreme weather events, and increasing losses from marine hazards.

More frequent meteorological hazards such as flooding from tropical storms and rainfalls have indeed caused disruptive impacts in the PRD: disrupting agricultural and mariculture production, damaging coastal defenses and embankments, destroying houses and facilities, shutting down transportation, and causing the loss of life. Sea level rise resulting from global warming represents a further threat and challenge in many parts of the region. The cumulative impact of these interrelated weather and climate phenomena have increased the costs of development in the PRD substantially. Fortunately, provincial and municipal governments have realized the importance of climate mitigation and adaptation, and are looking to the experiences of other delta cities around the world for valuable lessons about how best to strengthen urban sustainability and resiliency.

For planning processes to resolve the pressing issues of our day—such as climate change, traffic congestion, and social justice—plans must be made at the appropriate scale, must promulgate appropriate implementation tools, and must be enforced with legitimate authority. That is, our ability to meet critical challenges depends on the legal and institutional foundations of planning.

In the United States, responsibility for establishing these foundations for planning rests with the states, which in turn have delegated most land use authority to local governments. In Europe, the foundations of planning are established by each country, whose planning systems often feature national and regional plans as well as a mosaic of local plans. For better and for worse, these institutional foundations have framed the planning process on both sides of the Atlantic Ocean for most of the post-war period. But as the scope of our planning challenges continues to broaden, and discontent with the status quo continues to spread, several states and European nations have begun to experiment with new and innovative approaches to planning.

The opportunity to explore and discuss these issues brought scholars, practitioners, students, and others to Dublin, Ireland, in October 2012 for a two-day seminar sponsored by the Lincoln Institute of Land Policy and organized by the School of Geography, Planning, and Environmental Policy at University College Dublin and the National Center for Smart Growth at the University of Maryland. Held in the historic Newman House on St. Stephen’s Green, the meetings featured overview papers on planning in the United States and Europe and case studies of five U.S. states and five European nations. Each presentation was followed by commentary from a high-level official from the corresponding state or nation (see box 1).

A Framework for Spatial Planning in Europe

Planning in Europe is governed by a variety of traditions and governance structures (Faludi 2012). Some European nations have “unitary” governance structures, in which all land use authority ultimately rests with the national government. Italy and Spain have “regional” governance structures, in which land use authority is constitutionally shared between the national government and regional governments. Austria, Belgium, and Germany have “federalist” governance structures, in which particular land use functions are distributed among the national, regional, and local governments. Within these frameworks a variety of planning cultures and traditions have evolved: “amenagement duterritoire” in France; “town and country planning” in the UK; “Raumordnung” in Germany; and “ruimtelijke ordening” in The Netherlands. While these terms generally connote what “urban planning” means in the United States, there are important, nuanced, and fiercely defended differences.

The expression for urban planning used by the European Union is “spatial planning” (European Commission 1997, 24).

“Spatial planning refers to the methods used largely by the public sector to influence the future distribution of activities in space. It is undertaken with the aims of creating a more rational territorial organization of land uses and the linkages between them, to balance demands for development with the need to protect the environment, and to achieve social and economic objectives.

“Spatial planning embraces measures to co-ordinate the spatial impact of other sectoral policies, to achieve a more even distribution of economic development between regions than would otherwise be created by market forces, and to regulate the conversion of land and property uses.”

The European Union has no authority to engage in spatial planning, but directly influences spatial planning outcomes through regional development initiatives, environmental directives, and structural and cohesion funding. This goal is articulated in the European Spatial Development Perspective (ESDP) signed in 1998 by the ministers responsible for spatial planning in the member states and the members of the European Commission responsible for regional policy (Faludi 2002).

Modern spatial planning in the European context is broadly understood to include national, regional, and local planning, where national plans provide broad national development strategies and guidelines for plans at lower levels of government; regional plans integrate physical development with social, economic, and environmental policies but without site-level specificity; and local plans are site-specific and address the physical and urban design elements of the built environment. While none of the planning frameworks for the member nations matches this neat hierarchical ideal exactly, the ESDP has influenced planning activity in every nation.

The ESDP itself is based on longstanding European planning traditions dating to World War II, when national development or reconstruction plans were indisputably necessary for post-war reparations. Many European nations still have national development plans and complementary national spatial strategies. But the influence and importance of those plans has diminished steadily since reconstruction. In the last decade in particular, nations once known for their ambitious and extensive commitment to planning—France, Denmark, and the United Kingdom among them—have failed to adopt new national plans and expressly placed greater emphasis on regional and local plans.

National European Spatial Strategies and Frameworks

France

Although France is a unitary, centralized nationstate, the national government has never played a leading role in spatial planning. Rather, responsibility for spatial planning was officially transferred to regional and local governments in devolutionary reforms adopted in 1982 and 2003 (Geppert 2012). Although coordination between governments at different levels continues, this process results more often in joint investment strategies rather than in shared spatial visions or common objectives. Before most other nations, the French national government began focusing less on spatial planning and more on sectoral policies, leaving spatial issues for lower levels of government.

Denmark

Planning in Denmark historically began with a comprehensive national planning framework (Galland 2012). Over the last two decades, however, as a result of interrelated political and economic factors, the land use roles of national, local, and regional governments within the national territory have significantly transformed the scope, structure, and understanding of Danish spatial planning (figure 1).

Among the implications of this reform, several spatial planning responsibilities have been decentralized to the local level while regional planning for Greater Copenhagen and other sectoral functions have been transferred to the national level. Moreover, the recent abolition of the county level of government has increased the risk of uncoordinated spatial planning and decreased coherence across diverse policy institutions and instruments.

The Netherlands

The Netherlands has perhaps the longest and best-known tradition of national spatial planning, and its plans include industrial as well as detailed spatial policies (Needham 2012). For several decades, Dutch national plans influenced the distribution of people and activities throughout the country. In the first decades after World War II, all levels of government—national, provincial, and municipal—tended to work together in their spatial planning. In the 1990s, however, they started to move apart. In response, the national government strengthened its own powers over the local governments (a form of centralization), and at the same time reduced its own ambitions to pursue a national spatial strategy (a form of decentralization). The latest national spatial strategy expressly withdraws from some planning tasks previously carried out by the national government.

United Kingdom

In the early 1900s, the UK Parliament divested its direct powers to plan; instead, the powers of intervention, new state housing development, and regulation of private housing development were handed over to local governments (Tewdwr-Jones 2012). In the following decades, the central government did acquire new planning powers of its own as a consequence of World War II and the need to rebuild cities, infrastructure, and the economy in the national interest. Since 1945, central government has retained these powers, while also permitting the monitoring of local authorities in their operation of the planning system.

These powers have changed dramatically over the last 70 years. After 1999, devolution in Wales, Scotland, and Northern Ireland further fragmented the meaning of “national” in policy and planning terms. During the 2000s, the push toward regional spatial planning in England also rebalanced national planning matters toward sub-national interests. As a result of this trend in devolution, decentralization, regionalism, and localism over the last 20 years, it is increasingly questionable whether the UK now possesses anything that could be regarded as a national planning system, since so much has changed spatially and within policy-making institutions and processes across different parts of the country.

Ireland

Ireland is one of few European nations not following the trend toward decentralization of planning authority, partly due to the fact that its planning system has been fully decentralized (Grist 2012). Largely following EU guidelines, Ireland adopted a series of national development plans, the latest one being the National Development Plan 2007–2013. Based on recommendations in the previous national plan, the Department of Environment, Community and Local Government in 2002 developed the Ireland National Spatial Strategy. This strategy identified critical gateways and hubs and articulated plans to decentralize economic activity from Dublin and throughout the island.

Following a turbulent period that saw the rise and fall of the Celtic Tiger, blamed in part on lax local planning policies allied with extensive incentivizing of property development and political corruption, the country is now revisiting that strategy, strengthening regional development guidelines, and imposing new consistency requirements on local governments.

Under the new evidence-based planning regime, local plans must conform more closely with regional planning guidelines, and local plans will have quantitative limits on how much development can be allowed. The future role of the National Spatial Strategy is currently in the review process as the new government, elected following the property crash in Ireland, examines the planning and development issues that prevailed during the property bubble.

The Federal Government and Land Use in the United States

The U.S. federal government, like the European Union, has no authority to plan and manage land use, but probably has a greater influence on the location and nature of development patterns (Salkin 2012). Besides the billions of dollars it allocates for transportation infrastructure, social services, development, and redevelopment, the federal government is a major landowner of more than 630 million acres across the country. Federal regulations are also highly influential. The Clean Air and Water Acts, for example, impose no restrictions on land use per se, but in establishing targets for ambient air quality and nutrient loadings to rivers, lakes, and streams, both acts profoundly influence local land use plans, regulations, and development patterns.

More recently, President Barack Obama’s administration has established a new channel of federal influence on land use planning and regulation. While the federal government continues to refrain from direct intervention in local land use governance, the secretaries of the Departments of Transportation and Housing and Urban Development and of the Environmental Protection Agency signed a memorandum of understanding establishing the Sustainable Communities Partnership. To promote six principles of sustainable communities, these agencies launched a number of new grants programs, including the Regional Sustainable Communities Planning Grants. To be eligible for such a grant, local governments must form inter-organizational consortia that include the metropolitan planning organization (MPO), the central city, the majority of local governments, and a representation of civic and advocacy groups.

While the stated purposes of these path-breaking grants include urban revitalization, environmental protection, social justice, and sustainable development, an equally important purpose is to establish new inter-institutional relationships by promoting greater inclusion and participation. Regional Sustainable Communities Planning is now underway in 74 metropolitan areas across the country. It remains to be seen, however, whether the incentives offered to local governments to engage in regional planning are sufficient to get them to participate in regional plan implementation without additional state-level intervention.

State Plans and State Planning Frameworks

Every state established a framework for local planning and regulation in the 1920s and 1930s based on the standard planning and zoning enabling acts prepared by the U.S. Department of Commerce. Despite expectations of extensive institutional change, characterized in the “Quiet Revolution” more than 40 years ago, most states merely authorize local governments to plan (Salkin 2012).

Others, like Oregon, mandate, review, and approve local plans (Seltzer 2012). If local governments do not submit plans that meet the state’s land use goals and guidelines, the state can withhold funds or the authority to issue building permits. Several unique land use institutions also support the Oregon planning system, including a state planning commission, a land use court of appeals, and a directly elected regional government. Though simple in structure, and frequently challenged in the courts and at the ballot box, the Oregon system has a reputation as one of the most, if not the most, effective land use systems in the United States (Ingram et al. 2009).

California is among the states that delegated substantial land use authority to local governments. Although major development projects have to pass a complex mini-National Environment Policy Act process, and the California Coastal Commission was an innovative new statewide institution in its day, local planning remains dominant. But in 2008, the state adopted a bold new initiative to address climate change—Senate Bill 375, which required MPOs to develop transportation and land use plans that meet state greenhouse gas targets. The difficulty is that local governments, not MPOs, retain land use authority in California. MPOs and the state governments are providing incentives for local governments to adopt plans that conform with metropolitan plans, but it remains uncertain whether the combination of financial and other incentives are sufficient to nudge local governments to follow the MPO plans (Fulton 2012).

At the other extreme, plans for entire states are not common in the United States. In response to federal requirements, most states do have transportation plans, and some have economic development plans, workforce development plans, or climate action plans, but only five have state development plans—Connecticut, Delaware, Maryland, New Jersey, and Rhode Island.

New Jersey and Delaware have perhaps the best- and least-known state plans, respectively. New Jersey adopted its State Planning Act in 1985, requiring the state planning commission to develop, adopt, and implement the New Jersey State Development and Redevelopment Plan (Bierbaum 2012). The planning process included a complex cross-acceptance procedure for identifying and resolving differences between the state and local governments. Since its adoption, the influence of and attention received by the plan has ebbed and flowed over successive gubernatorial administrations. Most recently, Governor Chris Christie’s administration developed an entirely new state plan, focused primarily on economic development without the cross-acceptance process. The state plan commission, however, has not yet adopted the plan.

The Delaware plan is much less well-known and far less controversial than the New Jersey plan, and both the content and process are less complex (Lewis 2012). The Delaware plan includes five general land designations (figure 2). It depends on state-local coordination and relies on the threat of withholding infrastructure funding (of which the state pays a significant share) to incentivize compliance by local governments. Because the state did not begin tracking data on development patterns until 2008, and does not maintain spatial data on state expenditures, it is difficult to discern the impact of the approach on development and the consistency of state spending with the state plan map.

Maryland is the only state that rivals California and Oregon in its adoption of bold new approaches to planning, based on its long tradition of leadership in land use and environmental policy (Knaap 2012). Maryland established the first state plan commission in 1933, and broke into the national spotlight in 1997, when it adopted the path-breaking Smart Growth and Neighborhood Conservation Act. Since 1997 the use of state expenditures to provide incentives for smart growth has been the signature feature of the Maryland approach. Long before anyone in Maryland spoke the words “smart growth,” however, the state had passed legislation in 1959 that required the Maryland Department of Planning to develop and adopt a state development plan. More than 50 years later, the administration of Governor Martin O’Malley finally met that requirement.

On December 19, 2011, Governor O’Malley signed PlanMaryland, establishing the first new state development plan in the United States in many years (figure 3). But unlike state plans in New Jersey or Delaware, the Maryland plan is more procedural than substantive. Specifically, it established six plan designation categories and, following a longstanding Maryland tradition, enabled local governments to allocate land for any or all designated uses. State agencies would then target programmatic funds to each of these areas. Since the plan was signed, state agencies have been developing and refining implementation plans, and local governments have just recently begun submitting plans for state certification.

Concluding Comments

The frameworks for land use and spatial planning vary extensively across Europe and the United States. On both sides of the Atlantic, local governments carry much of the load, especially with respect to community, neighborhood, and site-specific details. But the role of regions, states, and nations remains important.

Contrary to its reputation in the United States, planning in many European nations has decentralized extensively. Few European nations are engaged in full-scale national plans that guide national investments and land use regulations. In fact, planning in Europe, while still far more comprehensive in sectoral details than in the United States, shares many policy features with its North American counterpart. An interesting exception is Ireland, which continues to expand the role of national and regional governments partly as a response to the recent period of extremely decentralized planning that failed to take into account and implement the national strategy. Ireland is also one of the few countries adhering to the broad principles of spatial planning formally adopted by the European Union.

In the United States, neither state development planning nor state approval of local plans is a rapidly growing practice. Indeed, despite the demonstrated success of the Oregon program and the growing recognition of the need for horizontal and vertical policy integration, land use planning in the United States remains a fiercely local affair. Although both the state of California and the federal government are providing financial incentives for intergovernmental coordination and planning at the metropolitan scale, it remains far from certain that incentives alone will secure the changes in local plans and regulations required to institute meaningful adjustments in land consumption, travel behavior, and access to opportunities.

New approaches are needed to make cites and metropolitan areas more productive, equitable, and environmentally sustainable in light of anticipated challenges in the future. If these issues cannot be addressed adequately, other kinds of experiments in institutional planning reforms may become more common in many countries.

Más que cualquier otra variable, el cambio en los valores del suelo a través del tiempo y del espacio brinda una perspectiva importante sobre la evolución de la estructura espacial de una ciudad. Mientras que la venta normal de una propiedad refleja el valor combinado del suelo y los edificios, el valor del suelo solo representa el valor real de una ubicación y sugiere expectativas sobre su futuro. Incluso si una parcela soporta la carga de un edificio anticuado, el precio del suelo refleja el valor actual descontado del flujo de retorno a la inversión que se podría obtener con un uso más intenso y óptimo de la parcela. El aumento rápido del precio del suelo en un área de la ciudad es una indicación clara de que la gente espera una alta demanda en el barrio durante un período de tiempo, lo cual es señal de oportunidades de inversión para los emprendedores inmobiliarios. Los cambios en el valor del suelo también pueden advertir a funcionarios municipales que es necesario efectuar cambios de zonificación e inversiones de infraestructura en una determinada área.

El valor del suelo es también un componente importante en el método de valuación de propiedades por costo, que es uno de los tres métodos utilizados comúnmente (junto con la comparación de ventas y el nivel de ingreso). El método de costo tiene tres componentes principales: (1) el costo de edificar la infraestructura existente como si fuera nueva en el momento de la tasación; (2) la depreciación del edificio a su condición actual; y (3) el precio de la parcela de suelo. Si se suma (1) a (3) y se resta (2), en general se obtiene una buena estimación del valor total de la propiedad. En las transacciones estándar de propiedades, sin embargo, no se pueden separar fácilmente el valor del suelo del valor de las estructuras. Las ventas de suelo vacante, que pueden indicar con mayor claridad el valor de un sitio, son relativamente raras en áreas urbanas grandes y edificadas, y por lo tanto hay pocos estudios existentes de ventas de suelo vacante (ver Ahlfeldt y Wendland 2011; Atack y Margo 1998; Colwell y Munneke 1997; Cunningham 2006). A veces se pueden usar las demoliciones para medir los valores del suelo, ya que cuando el edificio existente se demuele inmediatamente después de una venta, el suelo representa el valor total de la propiedad (McMillen 2006; Dye y McMillen 2007). No obstante, las demoliciones se tienden a concentrar en ciertos barrios de alto valor, y puede ser difícil obtener datos sobre demoliciones.

De todas las ciudades de los EE.UU., Chicago tiene la fortuna de contar con una fuente de datos, el Libro azul de valores del suelo de Chicago (Land Values Blue Book of Chicago) de Olcott, que reporta las estimaciones de los valores del suelo por cada manzana de la ciudad y por manzanas de muchos suburbios del condado de Cook durante la mayor parte del siglo XX. Olcott proporciona datos críticos para el procedimiento de tasación por costo. Después de determinar el costo y depreciación del edificio, el valor total de una propiedad se puede estimar multiplicando el tamaño de la parcela por el valor del suelo proporcionado en la serie del Libro azul. Este artículo se basa en un muestreo de datos de los volúmenes de Olcott (recuadro 1). Incluye una serie de mapas que proporcionan una imagen clara de la evolución espacial de Chicago durante el siglo XX, similar en espíritu al libro clásico Cien años de valores del suelo en Chicago (One Hundred Years of Land Values in Chicago) (Hoyt 1933).

Recuadro 1: Fuentes de datos para los valores del suelo en Chicago

El Libro azul de valores del suelo de Chicago (Land Values Blue Book of Chicago) cubre la ciudad y gran parte del condado suburbano de Cook con una serie de 300 mapas, cada uno impreso en una página del libro. A la ciudad propiamente dicha se le dedican 160 mapas individuales con un impresionante nivel de detalle. La mayoría de lotes que dan a la calle tienen un valor que representa el precio por pie cuadrado para un lote estándar de 125 pies de profundidad. También se indica el uso dado al suelo. Los lotes grandes y la mayoría de los suelos industriales tienen precios cotizados por acre (0,4 hectárea), u ocasionalmente por pie cuadrado (0,98 m2, para una profundidad de lote sin especificar. Los datos representan los valores del suelo para cuadrículas de 1/8 x 1/8 de milla (alrededor de 200 x 200 metros), que siguen de cerca la disposición de las calles de Chicago y por lo tanto se asemejan a manzanas urbanas. El conjunto de datos de cada año incluye 43.324 observaciones para toda la ciudad.

El Lincoln Institute of Land Policy ha proporcionado financiamiento para digitalizar los datos contenidos en el Libro azul de Olcott para una serie de años que cubre gran parte del siglo XX: 1913, 1926, 1932, 1939, 1949, 1961, 1965, 1971, 1981 y 1990. Se presenta una descripción más minuciosa del procedimiento en Ahlfeldt et al. (2011). La digitalización de mapas consiste en incorporarlos a un entorno SIG. Se calculan los valores promedio del suelo para cuadrados de 1/8 x 1/8 de milla (alrededor de 200 x 200 metros) superpuestos sobre los mapas. El conjunto completo de datos tiene más de 600.000 puntos para cada uno de los 10 años.

El libro de Olcott se dejó de publicar a comienzos de la década de 1990, y el último año de datos digitalizados es 1990. Para suplementar los registros de Olcott en años recientes, los autores obtuvieron datos de todas las ventas de suelo vacante en la ciudad entre 1980 y 2011. Se geocodificaron exitosamente más de 16.000 ventas, las cuales demuestran el enorme aumento en los precios del suelo durante el período anterior al colapso del mercado inmobiliario al final de 2006. Estos conjuntos combinados de datos brindan una oportunidad única para analizar el cambio de estructura espacial de una ciudad completa durante un período de tiempo prolongado.

Variación espacial en los valores del suelo

A pesar de su terreno plano, Chicago nunca fue una ciudad verdaderamente monocéntrica. El lago Michigan ha sido siempre una atracción, dado su valor panorámico, su efecto de moderación climática y la serie de parques que lo bordean. El río Chicago también ha tenido una influencia significativa sobre la ubicación de comercios y residencias. El desarrollo al norte del Distrito Comercial Central (Central Business District, o CBD) se demoró porque los puentes sobre el brazo principal del río se tenían que abrir con tanta frecuencia para dejar pasar el tráfico fluvial que el viaje a la zona comercial del Loop (bucle del tren elevado) era impredecible y largo. Los brazos norte y sur del río atrajeron tanto compañías industriales como desarrollos residenciales de bajo precio para los obreros, al tiempo que repelían las viviendas de alto precio diseñadas para los trabajadores del CBD. La ubicación de las calles principales, carreteras y líneas ferroviarias también tuvo un efecto significativo sobre los patrones de desarrollo. Por tanto, existen muchas razones para esperar una variación en la tasa de cambio en los valores del suelo a través de la ciudad.

Los mapas de la figura 1 (página 20) muestran esta variación espacial en los valores del suelo en Chicago a lo largo del tiempo. En 1913, los valores del suelo eran mayores en la gran zona que rodeaba el CBD y también eran bastante altos a lo largo del lago y algunas de las avenidas principales y bulevares que irradiaban de la zona céntrica. En 1939, este patrón era generalmente similar, junto con el crecimiento del lado norte en relación al lado sur de la ciudad. Los valores del suelo eran muy altos a lo largo de la ribera norte del lago, extendiéndose bien hacia adentro en la zona norte. El área del borde de la ciudad al oeste del CBD (el barrio de Austin) también tenía valores del suelo relativamente altos en 1939.

Para 1965, el patrón de valores del suelo había cambiado notablemente. Los valores del suelo muy altos estaban confinados a un área relativamente pequeña del CBD. El área de valor alto del barrio occidental de Austin era mucho más pequeña en 1965 que en 1939, y casi todas las áreas que anteriormente tenían un valor alto habían disminuido de tamaño.

Hacia 1990, sin embargo, la situación había cambiado drásticamente. El área con valores muy altos se extendía mucho más al norte y hacia adentro que antes. Las áreas del lado sur tenían valores del suelo relativamente altos en 1990, particularmente en la parte sur del Loop (cerca del CBD) y Hyde Park (a lo largo del lago Michigan, al sur del CBD).

Después de 1990, el patrón de revitalización continua de la ciudad se basa en un análisis de las ventas actuales de suelo vacante. La expansión del área de alto valor hacia el norte y el oeste del CBD es notable, y el lado sur cercano también gozó de un resurgimiento durante este tiempo.

La figura 2 (página 21) muestra cómo la reciente recesión afectó el crecimiento de los valores del suelo en Chicago cuando se lo expresa en función de la distancia del CBD. Las gráficas muestran el cambio en el valor promedio (logarítmico) del suelo a lo largo del tiempo para circunferencias con centroides a 2, 5, y 10 millas (3,2, 8 y 16 kilómetros) del CBD. En 1913, los valores promedio del suelo eran mucho menores a 10 millas (16 km) del CBD que en los anillos más cercanos al mismo. En la década de 1960, en contraste, había poca diferencia en los valores del suelo a estas distancias. Desde entonces, los valores promedio crecieron mucho más en el anillo a 2 millas (3,2 km) que en ubicaciones más distantes. Durante la Gran Recesión, los valores del suelo disminuyeron rápidamente en el anillo de 2 (3,2 km) millas, menos rápidamente en el anillo de 5 millas (8 km), y no disminuyeron en absoluto en el anillo de 10 millas (16 km). Por lo tanto, las áreas que tuvieron las mayores tasas de apreciación durante el período de crecimiento extendido también tuvieron las mayores tasas de depreciación durante la recesión.

La figura 3 ofrece una perspectiva distinta de la variación espacial de los valores del suelo a lo largo del tiempo. Los tres paneles muestran superficies promediadas de valores del suelo en 1913, 1990 y 2005. Las superficies de 1913 y 1990 se estimaron con los datos de Olcott, mientras que las estimaciones de 2005 se basan en ventas de suelo vacante. En cada uno de los tres años, los valores del suelo son mucho más altos en el CBD que en cualquier otro lado. En 1913, hay una gran cantidad de picos locales de valores del suelo en las intersecciones de las calles principales. Estas zonas eran distritos comerciales relativamente pequeños que atendían a los residentes locales antes de que el uso del automóvil se hiciera habitual. En 1990, el pico de valor del suelo en el CBD está acompañado por una meseta mucho más baja justo al norte, a lo largo de la ribera del lago. En 2005, esta meseta se había ampliado a un área grande que se extiende muy hacia el norte y hacia adentro de la ribera del lago. La región de altos valores del suelo también se ha extendido al sur a lo largo del lago, con un aumento local mucho más al sur en Hyde Park.

Persistencia de patrones espaciales

Los valores históricos del suelo son interesantes no sólo porque revelan cómo un área urbana ha cambiado con el tiempo, sino también porque el pasado sigue ejerciendo una influencia sustancial sobre el presente. Las ciudades no se reconstruyen a partir de cero en cada período. Los edificios están en pie mucho tiempo antes de ser demolidos, y los sitios que eran atractivos en el pasado tienden a ser deseables por mucho tiempo. Una de las características únicas del conjunto de datos de Olcott es que nos permite comparar valores del suelo de 100 años atrás con valores y usos del suelo en la actualidad.

La figura 4 (página 24) muestra la fecha promedio de construcción de los cuadrados de 1/8 x 1/8 de milla (alrededor de 200 x 200 metros). Se puede observar la reciente recentralización de Chicago en la forma de “rosquillas” de las edades de los edificios en torno al CBD. Los edificios más nuevos están cerca del CBD, mientras que los más viejos están en el siguiente anillo externo. Los edificios en la región más distante son los que tienen mayor probabilidad de haber sido construidos entre 1940 y 1970.

La figura 5 (página 24) resume esta relación comparando la media de la fecha de construcción con la distancia al CBD. Los edificios más viejos están en un anillo a solo 5 millas (8 km) del CBD.

Una buena medida de la densidad estructural es la relación entre el área edificada y el tamaño del lote. La teoría económica predice que las densidades estructurales serán altas en lugares donde los valores del suelo son altos. Las estructuras duran un tiempo largo. ¿Qué tan bien pueden los valores pasados predecir la densidad estructural actual? La figura 6 (página 24) compara la densidad estructural de los edificios en los padrones de tasación del condado de Cook en 2003 con los valores del suelo en 1913 y 1990. Este conjunto de datos incluye el área construida de cada estructura residencial pequeña (seis unidades o menos) en Chicago.

La altura de las barras indica las densidades estructurales: Las barras altas tienen relaciones relativamente altas de área construida por tamaño del lote. El color de las barras indica los valores del suelo: Las barras rojas tienen valores relativamente altos del suelo. Por lo tanto, deberíamos esperar una gran cantidad de barras rojas altas y barras verdes bajas. En general, los dos paneles indican una correlación positiva entre densidad estructural y valores del suelo. La correlación es particularmente evidente en el lado norte y en la ribera del lago. La correlación con 1990 es menos clara en los lados sur y oeste. Hay varias elevaciones en la superficie de densidad que no tienen una contraparte de valores altos del suelo. Una explicación de estos resultados, que coinciden con la reorientación de áreas de precios altos hacia el lado norte, es que las densidades relativamente altas en estas áreas son manifestaciones de un pasado en el que estas manzanas eran relativamente más valiosas y había un mayor incentivo para usar el suelo de manera más intensiva. El panel de 1913 de la figura 6 sugiere que los valores del suelo tienen en realidad mayor correlación con las densidades de edificios en 2003 que los valores de 1990. La causa de esta aparente anomalía se debe a que la densidad de edificios es un reflejo de las condiciones económicas en el momento de su construcción, y la mayoría de los edificios en esa parte de la ciudad fueron construidos hace mucho tiempo. El pasado sigue ejerciendo una influencia importante sobre el presente.

Conclusión

Los datos de Olcott proporcionan una imagen clara de los cambios en la estructura espacial de Chicago durante la mayor parte del siglo XX. Chicago, que nunca fue una ciudad monocéntrica, comenzó el siglo con valores del suelo muy altos en el CBD, a lo largo del lago y junto a las avenidas y bulevares principales que irradiaban del centro. Los valores también fueron altos en áreas de comercios minoristas ubicadas en las intersecciones de las calles principales. Para 1939, el lado norte de Chicago ya había comenzado a mostrar su hegemonía económica. Después, en la década de 1960, la ciudad sufrió un largo período de decadencia en el cual el CBD era la única concentración importante de valores altos del suelo. Desde entonces, la ciudad ha experimentado un resurgimiento notable. Los valores altos del suelo ya se extienden a casi todo el lado norte, y han repuntado en partes del lado sur. Nuestro análisis también muestra el importante papel del pasado en la estructura espacial actual de la ciudad. Una consecuencia de esta persistencia es que los valores del suelo de hace un siglo predicen mejor la densidad del inventario de viviendas actual que los valores presentes.

Responding to decades of poverty, poor housing, inadequate health care, rampant crime, deficient schools, poorly planned infrastructure, and inequitable access to services, citizens in about half of Brazil’s 60 major cities voted in October 2000 for mayors from left-wing parties noted for advocacy, honesty and transparency. These reform administrations are introducing new hopes and expectations, but they inherit long-standing mistrust of municipal bureaucrats and politicians, who traditionally have been lax and often corrupt. These new governments also confront the dismal fiscal prospects of low tax receipts, weak federal transfers, and urban land markets that produce segregated neighborhoods and profound inequalities.

The strongest left-wing party, the Workers’ Party (in Portuguese, the Partido dos Trabalhadores or PT), held on to the five large cities it had won in the 1996 election and added 12 more. These PT governments hope to universalize services, thus bypassing traditional top-down methods and giving residents an active role in their local governments. In the process these governments are reinventing local democracy, invigorating politics, and significantly altering the distribution of political and symbolic resources. The most remarkable case may be Porto Alegre, the capital of Brazil’s southernmost state, Rio Grande do Sul, where the PT won its fourth consecutive four-year term with 66 percent of the vote, an example that may have encouraged Brazilians in other cities to vote for democratic reforms as well.

Porto Alegre, like cities everywhere, reflects its national culture in its land use patterns, economic structure and distribution of political power. Brazil’s larger social system employs sophisticated mechanisms to assure that its cities continue to follow the same rules, norms and logic that organize the dominant society. Because Brazilian society is in many respects unjust and unequal, the city must constantly administer to the effects of these broader economic and political constraints.

At the same time, no city is a pure reflection, localized and reduced, of its national social structure. Any city can bring about and reproduce inequality and injustice itself, just as it can stimulate dynamic social structures and economic relations. To the extent that the city, and especially its government, determines events, then the effects can be positive as well as negative. It is not written in any segment of the Brazilian social code, for example, that only the streets of upper- and middle-class neighborhoods will be paved, or that water supply will reach only the more privileged corners of the city.

Participatory Budgeting

In Porto Alegre, a popular front headed by the PT has introduced “participatory budgeting,” a process by which thousands of residents can participate each year in public meetings to allocate about half the municipal budget, thus taking major responsibility for governing their own community. This reform symbolizes a broad range of municipal changes and poses an alternative to both authoritarian centralism and neoliberal pragmatism. Neighbors decide on practical local matters, such as the location of street improvements or a park, as well as difficult citywide issues. Through the process, the PT claims, people become conscious of other opportunities to challenge the poverty and inequality that make their lives so difficult.

Participatory budgeting in Porto Alegre begins with the government’s formal accounting for the previous year and its investment and expenditure plan for the current year. Elected delegates in each of 16 district assemblies meet throughout the year to determine the fiscal responsibilities of city departments. They produce two sets of rankings: one for twelve major in-district or neighborhood “themes,” such as street paving, school construction, parks, or water and sewer lines, and the other for “cross-cutting” efforts that affect the entire city, such as transit-line location, spending for beach clean-up, or programs for assisting the homeless. To encourage participation, rules set the number of delegates roughly proportional to the number of neighbors attending the election meeting.

Allocation of the investment budget among districts follows “weights” determined by popular debate: in 1999, weights were assigned to population, poverty, shortages (e.g., lack of pavement), and citywide priorities. Tension between city hall and citizens has led to expanded popular involvement, with participatory budgeting each year taking a larger share of the city’s total budget. Priorities have shifted in ways unanticipated by the mayors or their staffs.

Participants include members of the governing party, some professionals, technocrats and middle-class citizens, and disproportionate numbers of the working poor (but fewer of the very poor). This process brings into political action many who do not support the governing party, in contrast to the traditional patronage approach that uses city budgets as a way to pay off supporters. As one index of success, the number of participants in Porto Alegre grew rapidly, from about 1,000 in 1990 to 16,000 in 1998 and 40,000 in 1999.

The participatory process has been self-reinforcing. For example, when annoyed neighbors discovered that others got their streets paved or a new bus stop, they wondered why. The simple answer was that only the beneficiary had gone to the budget meetings. In subsequent years, attendance increased, votes included more interests, and more residents were happy with the results. City officials were relieved, too, as residents themselves confronted the zero-sum choices on some issues: a fixed budget, with tough choices among such important things as asphalt over dusty streets, more classrooms, or care for the homeless.

Participatory budgeting in Porto Alegre is succeeding in the midst of considerable hostility from a conservative city council and constant assault from right-wing local newspapers and television programs, all of them challenging participation and extolling unregulated markets. The municipal government depends for its support on the participants and their neighbors, on radio broadcasting, and on many who resisted two decades of military dictatorship, from 1964 to 1985. In electing four consecutive reform administrations, a majority of the population has managed to pressure a hostile city council to vote in favor of the mayor’s budget proposals, keeping the progressive agenda intact.

Changes in Material Conditions

In 1989, despite comparatively high life expectancy and literacy rates, conditions in Porto Alegre mirrored the inequality and income segregation of other Brazilian cities. A third of the population lived in poorly serviced slums on the urban periphery, isolated and distant from the wealthy city center. Against this background, PT innovations have improved conditions, though only moderately, for some of the poorest citizens. For example, between 1988 and 1997, water connections in Porto Alegre went from 75 percent to 98 percent of all residences. The number of schools has quadrupled since 1986. New public housing units, which sheltered only 1,700 new residents in 1986, housed an additional 27,000 in 1989. Municipal intervention also facilitated a compromise with private bus companies to provide better service to poor peripheral neighborhoods. The use of bus-only lanes has improved commuting times and newly painted buses are highly visible symbols of local power and the public interest.

Porto Alegre has used its participatory solidarity to allow the residents to make some unusual economic development decisions that formerly would have been dominated by centralized business and political interests. The city turned down a five-star hotel investment on the site of an abandoned power plant, preferring to use the well-situated promontory as a public park and convention hall that now serves as the new symbol of the city. And, faced with a proposal to clear slums to make room for a large supermarket, the city imposed stiff and costly household relocation requirements, which the supermarket is meeting. In another example, in spite of promises of new employment and the usual kinds of ideological pressures from the Ford Motor Company, the nearby municipality of Guíaba turned down a proposed new auto plant, arguing along political lines established in Porto Alegre that the required subsidies would be better applied against other city needs. (A state investigation in August 2000 found the former mayor, not “at fault” for losing the Ford investment.)

Nevertheless, daunting constraints in the broader Brazilian economic and political environment continue to limit gains in economic growth, demands for labor and quality jobs. Comparing Porto Alegre and Rio Grande do Sul with nearby capital cities and their states during the years 1985-1986 and 1995-2000, one finds few sharp contrasts. Generally, GDP stagnated, and per capita GDP declined. Unemployment rose and labor-force participation and formal employment both fell.

Given this limited extent of economic improvement, how can we account for the sense of optimism and achievement that pervades Porto Alegre? The city is clearly developing a successful experience with local government that reinforces participatory democracy. We believe the PT’s success lies in the way the participants are redefining local power, with increasing numbers of citizens becoming simultaneously subject and object, initiator and recipient, so they can both govern and benefit directly from their decisions. This reconfiguration is immediately discernible in the procedures, methods and behavior of local government.

After 12 years, Porto Alegre has changed not just the way of doing things, but the things themselves; not just the way of governing the city, but the city itself. Such a claim is clearly significant. Porto Alegre offers an authentic, alternative approach to city management-one that rejects not only the centralist, technocratic, authoritarian planning model of the military dictatorship, but also the competitive, pragmatic, neoliberal model of the Washington Consensus, to which the national government still adheres. This model imposes International Monetary Fund (IMF) orthodoxy and requires such “structural adjustment” imperatives as free trade, privatization, strict limits to public expenditures, and high rates of interest, thus worsening the conditions of the poor.

While most Brazilian cities continue to distribute facilities and allocate services with obvious bias and neglect of poor neighborhoods, the reconfiguration of power in Porto Alegre is beginning to reduce spatial inequalities through changes in service provision and land use patterns. We can hope that the effect will be felt in the formal structures of the city and eventually in other cities and in Brazilian society in general.

New Forms of Local Power

Political and symbolic resources normally are monopolized by those who control economic power, but radically democratic municipal administrations, as in Porto Alegre, can reverse power to block the favoring and reinforcing of privilege. They can interfere with the strict solidarity of economic and political power, reduce private appropriation of resources, and promote the city as a collective and socially dynamic body. In other words, a city’s administration could cease to honor the actions of dominant urban groups-real estate interests and others who use various forms of private appropriation of public resources for their private benefit. These actions may include allocation of infrastructure to favor elite neighborhoods, privatization of scenic and environmental resources, and the capture of land value increments resulting from public investments and regulatory interventions. Thus, a reconfigured, publicly oriented city administration permits access to local power for traditionally excluded groups. Such a change constitutes a quasi-revolution, with consequences that cannot yet be measured or evaluated adequately by activists or hopeful governments.

Are Porto Alegre’s experiences with municipal reform, participatory budgeting and democratic land use planning idiosyncratic, or do these innovations promise broader improvements in Brazilian politics as other citizens build expectations and improve the structure of their governments? The Interamerican Development Bank (IDB) is urging localities throughout Latin America to engage in participatory budgeting, following Porto Alegre’s example. Can reform-minded city administrations override the constraints of international markets and national policy? In recommending the formal and procedural aspects of the participatory budgeting technique, does the IDB overestimate the practical economic achievements and underestimate the symbolic and political dimensions of radical democracy?

The lesson of urban reform in Porto Alegre emerges not so directly in the economic market as in new experiences with power, new political actors, and new values and meanings for the conditions of its citizens. Even as citizens weigh their expectations against stagnating macroeconomic conditions, they can find hope in new visions of overcoming spatial and social inequalities in the access to services. These new forms of exercising political power and speaking out about land use and governance issues give the city’s residents a new capacity to make a difference in their own lives.

As a next step in the economic reforms begun in the post-Soviet period, momentum is growing in Poland for the introduction of a property tax based on market value. The recently established Department of Local Government Taxes and Cadastre within the Ministry of Finance is responsible for carrying out the reforms, and has invited the Lincoln Institute and other international organizations to advise them on developing an ad valorem property tax system.

Last October several Polish officials visited the Institute to learn about property taxation in the United States, and subsequently the Polish government requested support from the U.S. Agency for International Development (USAID) to bring international advisors to Poland for a series of seminars and meetings.

In January we traveled to Warsaw to participate in a week-long program on the legal and administrative framework needed to implement an ad valorem system. We made presentations at two seminars: one at the Sejm, the Polish Parliament, for its members and local government officials; and another at the Ministry of Finance for central government officials, professional experts and other interested parties. Our meetings with department officials focused on the draft laws being prepared by the ministry for introduction to the parliament later this spring.

The proposed ad valorem tax on real property in Poland will replace three existing taxes on urban, agricultural and forest property that are based on non-value-based rates per square meter of land and buildings. These taxes were introduced originally with purely fiscal objectives to expand the tax base beyond income and to capture wealth being diverted into real property assets. After the Soviet period, property taxes were recognized as an appropriate source of revenue for local governments. Since 1991 the revenues from the three existing taxes have been assigned solely to local governments (gminas).

The economic reforms introduced in the past decade by Deputy Prime Minister for Finance Leszak Balcerowicz have now reached such a stage of maturity that a market value-based tax on property is both feasible and desirable. There is an active and growing real estate market, including privatization of land holdings by local governments and secondary sales of residential and commercial properties. Ad valorem taxation will offer a stable source of revenue with a potentially broad and expanding tax base for local governments. It will provide the benefits of a more equitable distribution on taxes, as well as greater fiscal transparency and accountability.

An earlier USAID-funded feasibility study project in Krakow, in which the Institute also participated, resulted in legislative proposals for an ad valorem property tax in 1995. However, those efforts stalled in the face of complexities of land surveying, land registration and assessment administration.

Benefits and Obstacles

In this renewed effort, Polish officials are also focusing on the non-fiscal benefits of a value-based property tax, including its potential as a stimulus of real estate markets and mortgage credit institutions and as a tool for urban revitalization and more efficient land use. W. Jan Brzeski, president of the Krakow Real Estate Institute and adviser to the Deputy Prime Minister, has contributed to an understanding of these non-fiscal benefits through previous Lincoln Institute-sponsored research and education programs in Poland and other transition economies.

Considerable progress has been made in addressing some of the institutional obstacles to an ad valorem property tax that stalled the 1995 proposal. There is acknowledgment that a property tax information system and fiscal cadastre can be developed independently of title registries and land surveys that are as yet incomplete. Mass appraisal concepts and methods are more readily understood now and are viewed as opening new opportunities to the appraisal profession. Local governments have developed greater experience and influence to lobby for an autonomous source of revenue and greater independence in fiscal decision-making. Although local administrative capacity and expertise remain a concern for the over 2400 gminas, a possible solution may be found in placing fiscal cadastre and mass appraisal functions in the newly created regional governments (Powiats).

Discussions with Ministry officials concerning policy issues and implementation strategy focused on how to define market valuation in the law and how to educate local officials and taxpayers on its meaning and application. Current Polish law requires that detailed descriptions of taxation methods be written into legislation and that the local elected council approve the calculations. There is concern about an appropriate appeals system that will recognize both taxpayers’ rights and the government’s ability to achieve defensible mass appraisal models from less mature real estate markets. There is also a growing awareness of the importance of educating the public on the benefits and responsibilities associated with an ad valorem property tax.

The need to estimate implementation costs, develop effective administrative arrangements and assess the potential impacts of an ad valorem system has led some officials to propose one or more pilot projects before full implementation. However, this approach must be weighed against the possibility of losing the political momentum to enact ad valorem taxation in this parliament if legislative action is delayed until after pilot projects are completed.

To what extent are problems of distressed urban areas attributable to the property tax, and how can changes in property taxation help remedy urban decline? Political leaders, policy analysts and public finance experts gathered to discuss this complex and controversial issue during a Lincoln Institute seminar in New Haven on March 15.

John DeStefano, Jr., now in his second term as Mayor of New Haven, opened the session with a strong indictment of the property tax as a cause of urban ills. Described by the New York Times as “a leading spokesman for a growing number of people who believe Connecticut’s reliance on the property tax is harming not just the state’s cities, but its entire economy,” Mayor DeStefano argued that high relative property taxes in Connecticut were a direct cause of the state’s decline in population and jobs. From 1990 to 1995 Connecticut lost over 12,000 residents, while New Haven and Hartford suffered the two steepest population declines of any U.S. cities during that period.

His concern was shared by representatives from the Capital Region Council of Governments, the Regional Growth Partnership of South Central Connecticut, and the Connecticut Conference of Municipalities, which distributed a report stating that overdependence on the property tax was “reducing quality of life in all of Connecticut’s cities and towns.”

How can this widespread assumption linking property taxes to urban ills be tested, and what changes in the sources of local revenue could encourage urban revitalization? It may be that shifting demographic and economic patterns, such as the large defense industry cutbacks that have reduced Connecticut’s supply of high-wage jobs, have more to do with employment and population loss than does the property tax. If so, changing the property tax will not address the underlying causes of urban decline. Property taxes in Connecticut are not as far from the national average as a percentage of personal income as they might appear in absolute dollars (see chart).

Will lowering property taxes enhance economic growth if it is accompanied by an increase in other forms of taxation? Meeting growing needs in urban areas with a declining economic base is a problem of dependence on locally based taxation, not a problem of property taxation alone. Shifting from one local tax to another will not necessarily assist the neediest cities that have the least amount of revenue to draw upon.

Alternative Revenue Sources

What revenue sources can offer alternatives to the property tax as it is currently structured? The property tax base in the U.S. initially included real property and personal property, tangibles and intangibles alike; the restriction to land and buildings was the result of nineteenth-century reform efforts. Seminar speaker C. Lowell Harriss urged that these two portions of the property tax base be considered separately. The first, a tax on land values, deserves even more intensive use than it is getting, he argued, whereas the second, a tax on man-made capital such as buildings, machinery and inventories, warrants even more condemnation than it receives.

Donald Reeb of the State University of New York at Albany examined the actual process of obtaining state and local support for such a shift. He described successful efforts to permit Amsterdam, New York, to change from a single-rate property tax to a graded tax with a higher rate on land than on building value.

Robert Schwab of the University of Maryland discussed his own study of Pittsburgh’s two-rate tax, with buildings taxed five times as heavily as land. This case has particular interest for the issue of causality–whether or not the tax itself deserves credit for improving the local economy. Schwab drew a subtle distinction between finding that the tax had caused an increase in building and investment and that the tax had not impeded development. Although he felt that his study could not support the first proposition, he endorsed the second and emphasized its importance. This led to discussion of the special nature of a tax on land, which avoids the excess burden caused by most other forms of taxation in terms of lost efficiency.

Ronald Fisher of Michigan State University challenged the perception that heavy property taxation alone was the main problem for Connecticut’s economy. He pointed out that the state presents a complex mix of high personal income, relatively modest governmental expenditures, low income taxes, and consequent reliance on sales and property taxes. Connecticut only introduced a state personal income tax in 1991, and that tax has been the object of intense political protest and repeal efforts. In discussing various revenue sources, including local income taxes, local sales taxes and user charges, Fisher also questioned whether the absence of effective regional government in Connecticut could be partially responsible for the disparities between distressed central cities and prosperous suburban areas.

Tax-base and Revenue Sharing

Further discussion probed options for tax-base and revenue sharing as ways to reduce the tax burden on urban residents while meeting city revenue needs. The Connecticut Property Tax Reform Commission has recommended simply increasing state aid. Another option would reduce unfunded mandates in areas such as welfare and education.

A third alternative uses state funds to allow property taxes to serve as a credit against income taxes for low-income homeowners–and a refund to those with no income tax liability. Termed a “circuit breaker,” it is designed to prevent property taxes from exceeding a fixed proportion of income. The credit sometimes extends to renters as well. Over half the states provide some form of circuit breaker, but most are limited to senior citizens.

Lee Samowitz, a Bridgeport state representative, presented a proposal for regional service districts financed by a portion of the commercial and industrial tax base. Direct tax-base sharing of this type has its longest history in the Minneapolis-St. Paul region, which for 25 years has pooled 40 percent of the growth in the industrial and commercial property tax.

Yet such programs face formidable political hurdles, in part because most areas have fragmented or weak regional governments. According to economists Howard Chernick and Andrew Reschovsky, “Despite its success in Minnesota, the prospects for the establishment of tax-base sharing plans in other metropolitan areas are poor. The political representatives of those communities that would be net ‘losers’ under a tax-base sharing plan, or who believe they will be net losers at some point in the near future, will oppose tax-base sharing.”

Political obstacles have impeded plans for tax-base sharing in recent years in a number of states. However, the discussion in New Haven made it clear that property tax reform will become increasingly important as an element in the search for regional solutions to urban problems.

Over the past decade, the Lincoln Institute has developed and presented many courses on the interaction of land and tax policies and on the development of value-based land and real property taxation for policy makers and senior government officials from countries transitioning to market economies in Central and Eastern Europe and the Baltics. These courses address the economic and legal basis for value-based taxes as well as practical problems in their implementation.

As private property markets evolve, property changes hands and new wealth is invested in real estate. The introduction of ad valorem taxation is a natural step in the development of market-based economies. With economic growth and development, the revenue capacity of a value-based tax increases, and the tax can contribute to other important transition objectives such as privatization, government decentralization, infrastructure improvement and efficient land use. Nevertheless, the introduction of value-based taxation confronts both political and practical difficulties in developing an appropriate legal and administrative framework, as well as effective valuation, appeals and information systems.

The Baltic countries of Estonia, Latvia and Lithuania have been in the forefront of implementing value-based taxes on land (Malme and Youngman 2001). Estonia was the first of these new independent states to recognize the benefits of land taxation and to introduce a value-based land tax in 1993, followed by Latvia in 1998. Lithuania has been a leader in integrating and unifying real property cadastral, registration and valuation systems to strengthen nascent real estate markets and support real property taxation. Progress toward value-based taxation in Lithuania began with the integration of real property administrative units and the development of an automated central database of real property information in a self-funded state enterprise known as the State Land Cadastre and Register (SLCR). In 2001 the Ministry of Finance funded the SLCR to plan and develop a mass valuation system in preparation for the anticipated passage of laws that will introduce value-based taxation of real property throughout Lithuania. The first phase of this program was the development of land value maps that were completed and made public in 2003.

The Lincoln Institute and SLCR (renamed the Lithuanian State Enterprise Centre of Registers [SECR] in 2002) have worked collaboratively since 1997 to offer educational programs and document Lithuania’s progress (Malme 2001; Sabaliauskas and Aleksienė 2002). In 2003 the Institute and SECR developed a new executive course, Introducing a Market Value-Based Mass Appraisal System for Taxation of Real Property, for lawmakers and senior government representatives preparing to implement value-based taxes in other countries experiencing rapid political and economic change.

The course uses Lithuania’s experiences in market valuation as a case study, and SECR executives and specialists join core international faculty in the Institute’s Department of Valuation and Taxation to address the principles, strategies and practical problems raised by mass valuation of real property. The Lithuanian case study demonstrates how those responsible for developing that mass valuation system dealt with the problems they faced.

The first offering of the week-long course was presented in Vilnius, Lithuania, in October 2003 to a delegation from the Russian Federation, led by Alexey Overchuk, deputy chief of the Federal Land Cadastre Service of Russia (see related article). Participants included senior administrators of land valuation boards from various regions of Russia, officials from the federal ministries of Economic Development, Finance and Property Relations, and representatives from private companies involved in valuation system development. Two delegates from the National Cadastral Agency of the Republic of Belarus also participated. This course will be offered again in Vilnius in fall 2004 for a delegation from another country that is undertaking mass valuation for land or real property taxation.

The Institute’s June 2007 Land Policy Conference focused on decentralization—the degree to which local and provincial governments exercise power, make decisions about their revenues and expenditures, and are held accountable for outcomes. Because the services,regulatory constraints, and institutional environments provided by local governments are major factors in the location decisions of households and firms in urban areas, decentralization is a key determinant of policies that affect land and property taxation.
