In a swelter over shelter
with the broad consensus over the need to address the world's burgeoning urban crisis, much was expected of Habitat ii, the second un Conference on Human Settlements held June 3-14 in Turkey's very own 'mega-city', Istanbul. However, the question before the delegates was: how was the crisis to be addressed?
The Istanbul meeting, dubbed the 'city summit' by un secretary-general Boutros Boutros Ghali, marked the 20th anniversary of the initial Habitat conference at Vancouver, which for the first time had planted urban issues on the global agenda and offered visions of what a future city would look like. The difference today is the context -- the overwhelming scale and immediacy of the crisis. Problems of rapid urbanisation -- unemployment, homelessness, hunger, crime, random violence and declining air and water quality -- have reached almost unmanageable proportions.
In 1950, 30 per cent of the world's population lived in cities; only London and New York had a population of more than eight million. By 1995, the world's urban population had tripled to 2.5 billion -- about 45 per cent of the planet's population. In the last 46 years, the number of cities containing more than eight million residents has jumped from two to 20. In 1950, there were no such mega-cities in the developing world; today, there are 16. In less than 10 years, half of humanity will live in urban areas.
Of particular concern to policymakers is the fact that the bulk of urbanisation is occurring in developing nations, most of which are ill-equipped to deal even with existing urban problems. Habitat estimates that by the year 2025, 80 per cent of the world's urban population will live in developing countries. Unsanitary housing conditions have wreaked havoc in the developing world, from a recent cholera epidemic that swept through Peru to the plague outbreak of 1994 that hit India. Increasing inequalities in cities has led to social exclusion, creating war zones in Karachi, Lagos and Port-au-Prince.
Developed countries too face growing problems. Fiscal crises have prompted city governments to cut employment rolls, sparking widespread protests. Integration of immigrants remains a major challenge in rich countries. Meanwhile, income disparities amongst urban dwellers, within countries as also between developing and developed nations, continue to increase.
The delegates at Istanbul focussed on practical solutions, featuring more than 600 'best practices' -- initiatives that would address housing, credit, employment and other urban needs. Wally N'Dow, secretary-general of Habitat ii and head of the Nairobi-based un Centre for Human Settlements (unchs) called for "new and innovative partnerships" to provide the required political impetus for implementing the global plan of action. But the conference also saw renewed and, according to some, unnecessary, debate on previously discussed issues, including programmes for reproductive health and family planning, parents' and children's rights, recognition of same-sex couples etc.
A right to housing
The greatest controversy at Habitat ii centered around the responsibility of governments to provide housing. The debate pitted supporters of 'housing as a human right' against those governments, especially the us, which opposed housing as a 'stand-alone' right. After prolonged negotiations, in a trade-off between delegates, mention of the right to adequate housing was dropped from the preamble to the action plan, but left intact in other sections. Some housing rights activists praised the outcome as the first explicit recognition of an independent right to housing by Habitat. The housing language now includes water and sanitation as primary ingredients of an adequate standard of living, in addition to food, clothing and housing.
ngo activists also raised the issue of forced evictions, including removal of residents for development projects and raids on squatter settlements. But here again, they had to settle for a compromise. While the activists secured language protecting residents from forced, not just illegal, evictions, governments merely agreed to oppose "forced evictions that are contrary to the law".
Where's the money coming from?
Even these limited victories are meaningless without resources. The World Bank renewed its call for harnessing private firms to the cause of housing, shelter, basic city services and employment. But before that, governments need to provide an investor-friendly environment -- transparent, responsive, with consistent policies and greater decentralisation of authority.
Local government representatives, in their statement to country delegates (the first recognition at the un of local authorities as a distinct group), called for long-term private investment, rather than speculative ventures, in city projects. They also asked for greater revenue collection powers.
Around the world, national governments, while quickly divesting themselves of local and regional responsibilities, have not granted the required fiscal authority to local governments. "It is not just about finance at the local level," said India's Ela Bhatt, who has founded the widely acclaimed Self-Employed Women's Association (sewa) in Ahmedabad. "It is about the sustainability of the whole effort."
The Group of 77 (g-77) developing nations and China wanted to commit rich nations to upping development assistance to 0.7 per cent of their gross domestic product. Paula DiPerna, a development analyst, noted that increased assistance from developed countries and higher social spending by developing nations were "the keystones of the Rio compact", yet none of the Habitat seminars focussed on the decline, since 1992, of both.
Besides development assistance, the largest developing country concern to emerge at Habitat involved the institutions that are to coordinate implementation of the conference agenda. Developed nations, led by the us, did not support strong, independent roles for the unchs and the Commission on Human Settlements, choosing instead to "link" them to "the process of un reform". g-77 / China took this to mean consolidation of unchs into another un arm which might shift the agency from Nairobi to New York, a move resisted by the African delegates. Finally, however, us negotiators gave way and agreed in principle to end efforts to curtail the unchs and the Commission.
Fireworks and fizzle
On the final day of the conference, Cuba's Fidel Castro blasted the world's rich nations, almost all of which had not sent top leaders to Istanbul, for their apparent lack of political support. "Those who have almost destroyed the planet and poisoned the air, the seas, the rivers and the soils, are presently showing little concern over saving humankind," Castro told a packed house. "How many heads of state and government from the developed countries are attending this meeting today?" Postponements and delays in negotiations spilled over onto the last day. Persisting differences -- among others, on reproductive health, rehabilitation of local residents to former nuclear testing grounds (Marshall Islands) and recognition of original residents of occupied territories (an Arab initiative directed at Israel) -- dragged on till the gavel sounded.
Partnerships and political will
To consolidate Habitat ii's gains, two things are needed. The first, institutionalisation of partnerships, is already in progress. In the days preceding the official conference, local authorities, private firms and foundations and women's groups met to review the draft Habitat plan and were granted an opportunity to highlight concerns and make suggestions to government delegates.
At Istanbul, national governments repeatedly stressed the need, because of growing fiscal deficits, for granting greater responsibility to local authorities; the latter complained that they did not have the necessary authority to raise their own revenues for meeting newly-granted responsibilities for water, electricity, roads and other essentials. This leads to the other essential element: political will.
Habitat ii was marked by the virtual absence of world leaders, a fact that does not bode well for the future of decentralisation. Community groups noted that only top-level political support in respective nations can foster and sustain lasting partnerships.
Throughout the conference, no direct mention was made of the fact that nowhere on the planet is there a sustainable city of the sort envisioned by the delegates. Yet, as the 'best practices' demonstrate, there are plenty of examples illustrating various elements of sustainability. A feature common to all the best practices is broad-based participation. And it is on that front, Habitat organisers say, that most progress can be made. Real partnerships, uk's secretary of state for environment John Gummer pointed out, form "when even the poorest see that they have a part to play, that they can take ownership, that their contribution, however small, is a necessary part of the achievement of a new city. It is then that we have begun on the only process which can make the ideals of Habitat ii a success."
For better living
while the terms 'sustainable cities' and 'sustainable human settlements' were much in use at the recently concluded Habitat ii conference in Istanbul, with almost everyone apparently supporting the idea behind them, this unanimity was at best an illusion, as different groups gave different meanings to the terms. The ambiguity as to what 'sustainable cities' means allowed international agencies to claim that they were the leaders in promoting sustainable cities, when in reality they have contributed much to the growth of cities where sustainable development goals are not met. Governments in the world's wealthiest nations also supported the notion without admitting that it was in their cities that the largest reductions in resource use and waste generation are needed.
What is to be sustained? To many, especially environmentalists from Europe and North America, 'sustainable cities' means sustaining the biosphere. Their interest lies in reducing the ecological impact of cities, but in their discussions of how to do so, there is little or no mention of meeting urban human needs in a better manner. They have no interest in the 600 million urban dwellers in the Third World who live in housing that is so overcrowded and deprived of basic services that their lives and health are constantly at risk.
They assume that cities are responsible for most resource use and waste, pollution and greenhouse gas (ghg) generation, when it is not cities but particular commercial and industrial enterprises (or corporations) and middle- and upper-income groups sporting high-consumption lifestyles which are at fault. Most such enterprises and consumers may be concentrated in cities, but a considerable, and probably growing, proportion is not. In the North and the wealthier regions of the South, it is also the middle- and upper-income households living in rural areas or small towns that have the most unsustainable levels of resource consumption. Besides, in many cities in Africa, Asia and Latin America, the overall levels of resource use, waste generation and environmental degradation are very low compared to levels in the North. The issue here is not 'sustainable cities' but 'sustainable patterns of production and consumption'. Even among those proponents of 'sustainable cities' who are interested in meeting human needs, there is little agreement over what is to be sustained -- livelihoods, development projects, policies, institutions, businesses, the city, culture or economic growth. Many aid agencies think that sustainable development is achieved when their projects continue to operate or when their external support is withdrawn following the completion of their projects. In this instance, 'sustainable development' may have no explicit environmental concerns at all. The concept of 'social sustainability' was also raised in Istanbul, but it was unclear whether this was about social preconditions for sustainable development or the need to sustain specific social relations, customs or structures. Moreover, the term seems inappropriate if sustainable development is about meeting human needs and reducing the use of environmental capital, since this requires major changes to social structures.
A consideration of 'sustainable cities' necessarily has to take into account why so many people's needs are not being met today. This means considering the underlying economic, social and political causes of poverty or social exclusion. Besides assuming that plans for sustainable cities can be implemented within existing social and political structures, most of the literature on sustainable cities does not question the current distribution of power and the ownership of resources except where these are considered a factor in 'ecologically unsustainable practices'.
The trouble with international agencies
Virtually all international aid agencies and development banks claim to support sustainable development, but most give a low priority to meeting sustainable development goals in cities. Some support no urban projects at all. Amongst those that do, most give almost no importance to meeting human needs. International agencies that support urban projects are faced in most countries with the problem of weak and ineffective municipal authorities.
In such a scenario, the new conventional wisdom propounded at Habitat ii, embraced even by the World Bank, was to support 'community action'. However, these international agencies are structurally incapable of doing so. They have structures that were set up to support large capital projects implemented by recipient governments. The procedures by which projects are developed and funded do not allow them to support small, inexpensive community-developed projects. They can support a multi-million dollar water supply scheme, but not one involving us $2,000 for a water tank and distribution pipes in a settlement. Most aid agencies have devloped some ways to finance a few of these small projects through ngos or through special small project funds. But the bulk of their funding cannot be used in this manner.
Aid agencies have also given a low priority to encouraging more resource-efficient patterns of urban development. For instance, most agencies have never supported public transport. The exceptions are the bilateral agencies that fund large, expensive and often inappropriate metro schemes built by contractors from their own countries, where the motive was not sustainable cities but sustaining exports from the donor nation.
Global frameworks
A concentration on 'sustainable cities' focusses too much attention on achieving ecological sustainability within increasingly isolated 'eco-regions' or 'bio-regions': each city has to meet the resource needs of its population and enterprises from its immediate environs. But the goals of sustainable development lie in meeting human needs within all cities, accompanied by a level of resource use and waste generation within each region, nation and the planet that is ecologically sustainable. It is unrealistic to demand that major cities should only be supported by resources produced in their immediate vicinities. However, it is entirely appropriate to require that high consumption-high waste consumers and producers in cities greatly reduce their levels of resource use and waste. The damaging ecological impacts of their demands for fresh water and other resources on their surrounds must also be reduced and ultimately halted. We need frameworks to ensure the achieve ment of sustainable development goals worldwide, including appropriate frameworks for cities (which obviously will have multiple goals). They must include goals to ensure that all human needs are addressed and the different kinds of environmental capital are conserved.
In Figure 1, the top half is about meeting the economic, social and political needs of the present. In effect, meeting these needs lead on to the debates about 'development' (what and whose needs are to be met, who defines needs and who obtains the power and resources to ensure they are met). Meeting the needs of the present could thus be called the 'development' component of 'sustainable development'.
The bottom half of the figure is about ensuring that the meeting of present needs does not deplete the different forms of environmental capital; it is the 'sustainable' component of sustainable development. This component requires no depletion or degradation of four kinds of environmental capital:
The finite stock of non-renewable resources: Most of these resources (especially fossil fuels) are consumed when used. Others are not 'consumed', since the resource remains in the waste, for instance metals used in capital and consumer goods. For most non-renewable resources, there are energy and cost constraints to recovering a high proportion of the resource from waste streams; these may be considered partially 'renewable'. Biological diversity, one key part of environmental capital, might also be considered a non-renewable resource.
The non-renewable natural sink capacity or the finite capacity of eco-systems to absorb or dilute non-biodegradable wastes without adverse effects: One area of concern is the increasing concentration of pesticides. There are also large volumes of harmful non-biodegradable wastes (wastes from the nuclear power industry, for instance) that have to be stored and kept entirely isolated from eco-systems. One of the most pressing problems is the finite capacity of global systems to absorb ghg without changes in climate that can affect health and ecosystems.
The finite capacity of ecosystems to provide sustainable levels of renewable resources: Human use of some renewable resources (solar, wind or wave energy) does not deplete the resource. But many renewable resources (especially pastures, crops and trees) are renewable only within finite limits set by the ecosystems within which they grow. Fresh water resources are also finite; in the case of aquifers, human use often exceeds their natural rate of recharge and such levels of use are unsustainable. Many cities have depleted their local ground-water resources and now have to draw water from increasingly distant water-sheds, often with ecologically damaging impacts.
The renewable sink capacity or the finite capacity of ecosystems to break down biodegradable wastes: Although most wastes arising from production and consumption are biodegradable, each eco-zone or water body has a finite capacity to break down such wastes without itself being degraded.
Ecological sustainability
Many of the goals shown in Figure 1 for meeting needs are already among the responsibilities of city governments. This does not imply that municipal authorities should provide all the basic services. As was stressed at Habitat ii, many of the most innovative and cost-effective basic service programmes in cities are run by community organisations and ngos. City authorities, on their parts, must act as supervisors and supporters of private or community provision and ensure universal coverage. To develop their concern for the 'sustainable' component of sustainable development, city authorities should focus on two new aspects: firstly, a concern for the environmental impact of city-based production and consumption on the needs of all people (not just those within their jurisdiction); and secondly, an understanding of the finite nature of many natural resources and ecosystems, and of the capacities of ecosystems in wider regional, national and international contexts to absorb or break down wastes. Historically, these have not been considered within the remit of city authorities. Indeed, many Northern megapolises have made progress in achieving sustainable development goals within their own boundaries by drawing on the environmental capital of other regions and on the waste-absorption capacity of 'global commons'.
Adding a concern for 'ecological sustainability' onto existing development concerns means setting limits on the rights of city enterprises or consumers to use scarce resources and to generate non-biodegradable wastes. This has many implications. Perhaps the most important for cities in the North and the wealthier countries in the South is the role of city and municipal authorities in promoting the needed delinking of high standards of living from high levels of resource use and waste generation.
Poverty and environment
There is an assumption in most literature on sustainable development and on sustainable cities that poverty is a major cause of environmental degradation. But low-income groups contribute very little to the depletion of most of the environmental capital discussed above. Their consumption levels for non-renewable resources is very low, given the fact that they lack the income to own resource-intensive capital goods like automobiles.
The levels of waste they generate per person are much lower than those generated by richer groups. Also, low-income households often re-use or recycle much of what wealthier households would have thrown away. Their contribution per person to ghg and to stratospheric ozone depleting chemicals is very low in comparison to wealthier groups. The only components of natural capital to whose depletion low-income groups may contribute are certain renewable resources like soil, forests or fresh water. However, low-income groups living in urban areas contribute little or nothing to this.
Dwelling in rural areas, the poorer farmers, pastoralists and forest-users have often been targeted as the principal perpetrators of unsustainable resource use. But this assumption is of doubtful verity, as the poverty of this section of the poor is a result of them having so little land and such inadequate access to forests. Most deforestation and soil erosion takes place on land which the poor do not own and to which they have no access; wealthy farmers, landowners, commercial companies and governments own most of the world's farmlands and forests.
There is certainly a link between poverty and serious problems of environmental health in urban areas as low-income groups lack safe and sufficient water supplies, provision for sanitation, safe and adequate housing and access to health care. But the environment-related diseases and injuries that low-income households suffer from are not depleting soils or forests; they are not using up non-renewable resources; they are not seriously disrupting ecosystems. Perhaps this is why they are so often forgotten by those preaching the concepts of 'sustainable development' or 'sustainable cities'.
