Increasing socio-economic and spatial disparities in Latin American cities have prompted a revival of interest in equity-oriented government policies to reduce those disparities. However, solutions to the major urban problems being faced today must go far beyond the implementation of inconsistent and narrowly defined actions. The solutions must ensure equity for all sectors of society. In too many places, entire neighborhoods are forced to exist under deplorable living conditions while government agencies seek to evict residents in the name of environmental protection. It is evident that urban legislation can no longer ignore the rights of people to have a place in which to live in security and dignity.

The critical impact of land inequity on the urban environment requires that the urban poor gain access to the technical information necessary to better negotiate their concerns with public officials. My research explores the role of environmental education in low-income communities in developing countries. Taking a perspective based on self-help capacity building, my goal is to develop programs to train community leaders at the grassroots level to deal more effectively with local land use conflicts and environmental risks.

Impacts of Land Inequity

Like many Latin American cities, Rio de Janeiro is strongly affected by prevailing poverty and environmental degradation. Complex factors are involved: economic instability, inequitable land ownership, short-sighted development policies, and a lack of a democratic system that provides for human rights and freedoms. In my view, the problems experienced by Rio de Janeiro during the last few decades are mainly a result of existing “apartheid” urban planning assumptions and a lack of political will to incorporate the popular sectors in land use policy making.

In the region of Baixada de Jacarepaguá-at the heart of the core expansion area of Rio de Janeiro-the extraordinary process of urban growth since the 1970s has provoked dramatic changes in the landscape, as well as a variety of environmental problems. Amidst the spectacular natural beauty of lagoon ecosystems, mangrove forests and wetlands, the region remains home to a large population of urban poor who live in favelas-shanty communities resulting from largely uncontrolled urbanization of public land.

During the 1980s and early 1990s, the region enjoyed an unprecedented development boom that has fostered unsustainable patterns of land use. Discrimination against the poor inhabitants and inequalities in landownership allowed landowners and speculators to capitalize on the boom by formally obtaining titles and subdividing the land. In addition, a select group of private builders injected themselves into the local scene with multiple court permits to develop the region for high-income residential condominiums, commercial establishments and industrial enterprises.

Increasing pressures on the land snowballed into a wide range of protests between the popular sectors and the powerful land developers, posing the threat of forced eviction of the poor inhabitants. The accumulated discontent against the government for failing to control land speculation and ensure protective legislation created an extremely dangerous situation. Violence and persecution claimed the lives of 30 community leaders, presidents of local community associations, their family members and relatives. The murders were carried out by what are known in the region as “extermination squads,” and no criminal investigation has taken place.

The Vicious Cycle of Poverty and Environmental Degradation

Since poverty and environmental degradation are interdependent, it is appropriate to think of environmental concerns in terms of social justice. My research revolves around the problems of inequality and the environmental risks faced by the residents of the Via Park village-an informal settlement located in the region of Baixada de Jacarepaguá. A basic question arising from this research is to what extent can improved access to land equity actually contribute to mitigate the factors that encourage environmental degradation. By connecting land use issues to the learning process of environmental education, the research demonstrates that environmental degradation is a recurring phenomenon manifested in the inequitable ways land has been used and distributed in the region.

Via Park village has been caught in a serious land use struggle since the 1970s, when urban development began to impact many traditional fishing communities in the area. Builders were eager to lobby the government to break the fishermen’s land tenure system, which was enforced by law, and thereby turn the land over to market forces. In the 1980s, the area was designated a public reserve for environmental preservation, enshrined in Article 225 of the Brazilian Constitution (1988). Since the village was located on protected land, the city’s planning authorities then argued that the Via Park residents had no legitimate claims of ownership.

Living in an atmosphere of fear and at mercy of the land developers and speculators who continued to flourish, the Via Park residents started illegally subdividing and selling small parcels of land to new settlers. The growth of the poor population and the concentration of land ownership and speculation contributed to the expansion of informal land markets into nearby low-income communities.

Underlying these practices was a more complex system of commercial transactions and civil relations governing the invasion of vacant lands, as well as the division and sale of plots. Throughout Rio de Janeiro, land development through informal channels is the predominant “territorial pact” by which disadvantaged local groups have been able to gain access to land and housing. At the same time, agents from the “formal world” have developed political arrangements to support and take advantage of existing informal land markets.

It was in this context that a program for grassroots environmental improvement was conceived and eventually implemented in Via Park village. However, given the residents’ long history of exclusion-including threats of forced eviction-they remained suspicious. It became clear that successful program implementation would depend on managerial strategies based on an integrated vision of the geographic/ecological and social/cultural environment.

If the dilemma of poverty and environmental degradation is to be overcome, then the task of improving the environment must be shown to be compatible with the struggle for land equity. This innovative approach toward environmental education differs from traditional methodology, which is generally more concerned with simply introducing physical changes to the environment. The key here is to focus on the conditions that are favorable for the development and exercise of a sense of “community belonging”-a tangible expression of shared sentiments, values and identities where land is understood not only as a component of wealth, but as a common settled place invested with symbolic meanings.

Lessons of Via Park Village

While there is no single solution to the social and environmental vulnerability of the urban poor living in the Via Park village, their experience does offer some insights. One alternative suggests creating “urban natural reserves” integrated into the community where those threatened with forced eviction are encouraged to maintain their traditional lifestyles. In exchange, government authorities at all levels would accept the obligation to promote land equity, giving security of tenure and protection to those forced by circumstances to live in informal settlements.

Aspects of the environmental education program initiated in the Via Park village are applicable to other Latin American cities. The fundamental principle is based on insuring respect for the inherent identity of the community. The experience of the Via Park residents demonstrates that local action can contribute to consolidating a socio-political struggle for land equity with protection of the environment. This is in line with current thinking about land use and environmental management, which suggests an integrated approach that acknowledges the leadership role of the local residents.

The Via Park case reveals that a routine excuse being used to justify evictions is “protecting the environment.” In other words, the urban poor most often accused of being the primary protagonists of environmental degradation are in reality the greatest victims. For the 450 residents of the Via Park village, the trauma of being forcibly evicted from their homes will never be overcome. Five people, including two children and one woman, lost their lives in the confrontation. The Via Park village, now destroyed by bulldozers, still reminds us that hope for land equity lies in community solidarity, effective governance and democracy.

Most people are not particularly fond of paying taxes of any sort, but the discontent with one particular type of public levy, the local property tax, is gaining momentum across the country. Disgruntled homeowners are demanding that governors and mayors find alternative methods to raise revenue in order to relieve their own property tax burden.

Decades ago this discontent led to such tax limitation measures as Proposition 13 in California and Proposition 2½ in Massachusetts. More recently, this movement has been driven by sharply rising property tax levies in many cities and suburbs as a result of the extraordinary appreciation in property values over the past few years. The high visibility of the property tax, which in contrast to sales and income taxes is often paid annually in one or two large installments, makes this form of revenue generation an attractive target for taxpayer antipathy.

People who work with me are often surprised by the extent to which my philosophical canon derives from low-budget offbeat films, typically from the 1980s. When in need of wisdom, I frequently turn to the teachings of Repo Man or, for this essay, Terry Gilliam’s allegorical masterpiece Time Bandits. In the movie, a group of public workers are employed by the Supreme Being to fill holes in the time-space continuum left from the haste of creating the universe in seven days: “It was a bit of a botched job, you see.”

Like the Time Bandits, policy makers are often tasked to fill holes—actual potholes in roadways, or more theoretical holes that are the artifacts of dysfunctional private markets. One big hole that policy has struggled for decades to fill is the inadequate supply of affordable housing. For example, housing economists in the United States have become quite adept at tracking the size of the hole, which has only become harder to fill since the federal government committed to address it as a national policy priority beginning with the Housing Act of 1949, part of President Harry S. Truman’s Fair Deal.

Perhaps our collective failure to solve the affordable housing deficit over the last 66 years stems from wrongheaded analysis of the problem, and the conclusion that market-based solutions can be designed to solve the mismatch between the supply of affordable housing and demand for it. In his 1949 State of the Union address, President Truman noted that to fill the needs of millions of families with inadequate housing, “Most of the houses we need will have to be built by private enterprise, without public subsidy.”

To support this claim, permit me a short departure into market theory. From the now-preferred mathematical approach to economic analysis, a market is simply a system of partial differential equations that is solved by a single price. The partial differential equations capture the complex decisions made by consumers and producers of goods, reconciling tastes, preferences, and budgets of consumers with the technical complexities of producing goods to arrive at a price that clears the market by settling all transactions that suppliers and consumers of goods are willing to make.

Acclaimed economists Arrow, Debreu, and McKenzie proved the theoretical existence of a single set of prices that can simultaneously solve for the “general equilibrium” of all markets in a national or global economy. One important aspect of this Nobel Prize–winning contribution was the observation that a unique price cleared each market—one market, one price. There was no expectation that a single price could maintain equilibrium in two markets. But this is the fundamental flaw of the housing market—it is actually two markets, not one. Housing markets supply both shelter for local consumption and a globally tradable investment good made possible by broad capital markets that serve global investors. This dual-market status used to be more descriptive of owner-occupied housing, but, with the proliferation of real estate investment trusts (REITs), rental markets are now in the same boat.

Markets for consumption goods behave very differently than investment markets, responding to different “fundamentals.” On the supply side, prices for consumption goods are dictated by production costs, while prices in investment markets are dictated by expected returns. On the demand side, such things as tastes and preferences, household incomes, and demographics determine the price of housing as shelter. Investment demand for housing is dictated by factors like liquidity and liquidity preferences of investors, expected returns on alternative investments, or interest rates.

In developed countries, global capital markets and the market for shelter collide locally with little chance of reconciliation. Local households compete with global investors to decide the character and quantity of housing that is produced. In markets that attract global investment, plenty of housing is produced, but shortages of affordable units are acute, and worsen over time. This is because a huge share of new housing is produced to maximize investment return, not to meet the needs of the local population for shelter. For example, there is no shortage of global investment willing to participate in developing $100 million apartments in New York City. But affordable housing, being much harder to finance, is in short supply. And in markets that have been abandoned by global capital, house prices fall below production costs, and surplus housing accumulates and decays. In extreme cases such as Detroit, market order can only be restored by demolishing thousands of abandoned homes and buildings.

Perhaps it is time that we reconsider the analysis that led President Truman, and thousands of housing policy makers after him, to conclude that one could forge market-based solutions to the challenge of sheltering a country’s population. Truman concluded that “By producing too few rental units and too large a proportion of high-priced houses, the building industry is rapidly pricing itself out of the market.” But Truman was thinking about the market for shelter, not investment. It is remarkable to note that the number of housing units supplied in developed countries such as the United States significantly exceeds the number of households. In 2010, the U.S. Census estimated that there were 131 million units of housing in the country and 118 million households—one in seven housing units were vacant. It is even more shocking to note that in the United States this oversupply of housing characterizes every metropolitan market in the country—even metropolitan markets with extreme shortages of affordable housing. In 2010, 8.5 percent of housing units were vacant in Greater Boston, 9.1 percent in the San Francisco Bay area, and 10.2 percent in Washington, DC. The problem is that many households have insufficient incomes to afford the housing that is available.

In the end, rather than fill the holes in the fabric of time and space, the Time Bandits decided to take advantage of them to “get bloody stinking rich.” The bandits sought to capitalize on celestial imperfections in the same way that global investors seek returns from short-term market dislocations. To illustrate the dangers of naked speculation in unregulated markets, consider an apocryphal tale from a very different market. In 1974, heavy rains during planting season in Bangladesh suggested that rice might be in short supply at harvest time. In anticipation of these shortages, rice prices started to rise. Savvy commodity speculators realized that there would be a good return on any rice that was held off the market. Despite the fact that the actual harvest produced a bumper crop, the interaction between market expectations and market manipulations by commodity investors produced one of the worst famines of the 20th century—with an estimated 1.5 million famine-related fatalities. The famine was not the result of real food shortages. The collision of the market for goods and the market for speculative investment priced rice out of the reach of the local populations, with landless families suffering mortality at three times the rate of families with land.

Perhaps shelter and food are too important to be left to unregulated markets to allocate. In light of the damage that the conflict between the market for goods and the market for investment can inflict on local populations, perhaps public policy should focus on protecting a share of the market—and the public—from the ravages of speculation. In this issue, we describe some nascent efforts to produce permanently affordable housing by insulating it from speculation—through community land trusts, inclusionary housing, and housing cooperatives. Miriam Axel-Lute and Dana Hawkins-Simons discuss the mechanics of organizing local community land trusts. Loren Berlin describes efforts to preserve affordable housing in the form of manufactured homes and to promote permanent affordability of that stock through the conversion of manufactured housing communities to limited equity cooperatives.

On more cautionary notes: Cynthia Goytia discusses the ways that low-income communities circumvent housing regulations that drive up housing costs to produce their own affordable but substandard shelter in informal settlements around Latin American cities; and Li Sun and Zhi Liu discuss the tenuous status of one-quarter of urban Chinese households that purchased affordable shelter with uncertain property rights on collectively owned land at the rapidly developing edge of cities and in “urban villages,” former rural settlements now surrounded by modern construction. As capital markets deepen in these countries, the competition between housing as investment good and housing as shelter will likely exacerbate informality in Latin American cities and make property rights of these Chinese families more precarious. After almost seven decades of failed efforts to get private markets to meet populations’ needs for affordable shelter, it might be time to develop, and to export, another approach that is based on a more realistic understanding of the complexity of housing and capital markets.
