KNOWLEDGE PAPERS BUILDING SUSTAINABILITY IN AN URBANIZING WORLD A Partnership Report Written by Daniel Hoornweg and Mila Freire Edited by Daniel Hoornweg, Mila Freire, Julianne Baker-Gallegos and Artessa Saldivar-Sali July 2013, No. 17 Urban Development Series Produced by the World Bank’s Urban Development and Resilience Unit of the Sustainable Development Network, the Urban Development Series discusses the challenge of urbanization and what it will mean for developing countries in the decades ahead. The Series aims to explore and delve more substantively into the core issues framed by the World Bank’s 2009 Urban Strategy Systems of Cities: Harnessing Urbanization for Growth and Poverty Alleviation. Across the ï¬?ve domains of the Urban Strategy, the Series provides a focal point for publications that seek to foster a better understanding of (i) the core elements of the city system, (ii) pro-poor policies, (iii) city economies, (iv) urban land and housing markets, (v) sustainable urban environment, and other urban issues germane to the urban development agenda for sustainable cities and communities.

Why Urban Sustainability Matters Photo: Tran Thi Hoa/World Bank 2 BUILDING SUSTAINABILITY IN AN URBANIZING WORLD Sustainable Development in the Urban Century Key Messages ` Sustainable cities are critical to sustainable development, given their position as engines of economic growth, centers of population growth and resource consumption, and crucibles of culture and innovation. ` Cities must adopt sustainable development policies as soon as possible because today’s infra- structure investments will be locked in for hundreds of years. This is all the more urgent in developing countries that are rapidly urbanizing. ` Sustainable cities should be deï¬?ned broadly, integrating environmental, economic, and social objectives, and should be supported with a comprehensive and customizable how-to menu. ` Making cities sustainable requires addressing knowledge gaps, broadening participation across stakeholders, and incentivizing behavioral change at the individual, corporate, and local government levels.

This concept of sustainability is best illustrated by natural ecosystems, which consist of nearly closed loops that change slowly. For example, in the food cycle of plants and animals, plants grow in the presence of sunlight, mois- ture and nutrients and are then consumed by insects and herbivores that, in turn, are eaten by successively larger animals. The resulting natural waste products replenish nutrients, which allow plants to grow and the cycle to begin again. If humans are to achieve sustainable devel- opment, we will have to adopt patterns that reflect these natural processes. The model of a closed-loop ecosystem was ï¬?rst proposed by the World Federation of Engineering Organizations in a 1990 publication, and other authors have since suggested modiï¬?cations to this model.

Functioning ecosys- tems are the foundation of human wellbeing and most economic activity, because almost every resource that humankind utilizes on a day-to-day basis relies directly or indirectly on nature. The beneï¬?ts that humans derive from nature are known as ecosystem services, which can be divided into four categories: provisioning services (what we consume directly), regulating services (what protects us from extreme events), cultural services (natural systems that we use for recreation, religious or spiritual purposes), and supporting services (the underlying processes that deliver the other services).

Economic Valuation BOX 7 of Ecosystem Services The economic valuation of ecosystem services is an emerging science that has seen experts attempt to quantify the contribution of such services to the local or national economy. While the process is challenging, it allows policy makers to propose policies relating to the natural environment that can be weighed against other competing activities, such as large- scale infrastructure development. For instance, in Chicago, USA, urban trees are estimated to provide a service for air cleansing that is equivalent to US$9.2 million dollars, and their long-term bene- ï¬?ts are estimated to be more than twice their costs.

Dense cities that are served by integrated public transport systems can have high prosperity with relatively low emissions. ` While green investments may be proï¬?table, market uncertainty in the short term will require support from the public sector to compensate for lack of information. ` An economic downturn may be an ideal time for public investments in sustainability, which can boost productivity and employment .

It can also improve human well-being directly or indirectly. For example, alleviating trafï¬?c congestion directly reduces air pollution, but also indirectly improves the produc- tivity and economies of scale typically offered by cities.

Both developed and developing country cities need to enact policies that increase energy efï¬?ciency and promote cleaner energy sources for electricity generation, buildings, and urban transport. ` Buildings constitute the largest opportunity to improve demand-side energy efï¬?ciency. Green building standards target the operational phase of building life, while embodied energy in buildings can be conserved through the adaptive reuse of historic built assets. ` Emissions from transport are likely to increase dramatically as demand for private transpor- tation grows in the developing world. Transport sector investments need to provide a viable alternative to automobile use. ` Waste generation is increasing in quantity and complexity with urban growth.

Land- use zoning policies that allow for higher densities and greater mixing of residential and commercial uses enhance transportation goals by reducing trip distances, while strategic mass transit linkages can attract devel- opment and promote compact growth. However, density can also be perceived as a cost—crime and violence tend to be higher in dense places, and local trafï¬?c is worse. These costs must be outweighed by the beneï¬?ts of agglomeration and urban amenities, including prox- imity to high-quality public transportation (Cheshire and Magrini 2009). Long-term growth plans aim to strike this balance in a number of OECD metropolitan areas, including London, New York, and Paris.

Many of the world’s largest cities are located on low-lying coasts, rivers and other vulnerable areas where the impacts of climate change will be most severe. ` The need for cities to reduce their emissions is well-established, but the need to adapt to climate change and build resilience in cities is not as widely integrated into urban planning. Integrating mitigation and adaptation efforts at the local government level is critical as it will lead to more robust climate change policies and strengthen climate action in cities. ` As cities prepare for changing weather patterns, they become more resilient. Resilient systems have the capacity to absorb external shocks and continue to function by reorganizing and adapting. In fact, change and disruptions can create opportunities for development, innovation, and prosperity in a resilient city. ` Urban resilience increasingly depends on multi-sectoral partnerships involving local government action, private sector participation, and community-based risk management.

The World Bank estimated annual average household investments in urban housing in response to climate change at $2.3 billion per year in 2010, rising to $25.6 billion per year by 2050. These costs would be even higher if they also accounted for slums. Most informal settlements in developing countries share characteristics that inten- sify the vulnerability of their residents to climate change. These include poorly constructed buildings, inadequate infrastructure, lack of safe drinking water, drainage, and sanitation services, and severe over- crowding with attendant public health impacts. In regions prone to flooding, floods are more severe in sprawling urban spaces than in inland towns, in part Photo: Julianne Baker Gallegos/World Bank because of weak urban planning.

PART II: THE PATH TO SUSTAINABILITY 75 Measuring Urban Sustainability Key Messages ` Urban metabolism analyses look at how cities consume, produce and transform materials and energy. As measures of urban sustainability, these are more comprehensive and credible than a traditional ecological footprint. ` Data sources for cities have been improving, and metabolism indicators are now being calculated regularly and rigorously. All cities should begin measuring material flows and other environ- mental and social data. The Large Urban Areas Compendium initiated by the World Bank aims to support this. ` More standardized data enables cities to be compared in a typology. While requiring strong assumptions, this type of analysis sheds light on how cities are evolving in terms of their economic growth, urbanization and greenhouse gas emissions. Increasing wealth and urban- ization usually lead to greater emissions, but some cities and countries have reversed the trend. Poor cities face a greater challenge in doing so, given their limited capacities. ` In addition to metrics for efï¬?ciency and environmental impacts, cities need a credible, standardized Urban Resilience Index. This would help focus attention on the urgency of mitigating risks from climate change in cities. To assess a city’s sustainability, we need to consider a simple typology for comparing and bench- how urban systems contribute positively to growth, marking cities. Finally, we consider how to apply prosperity, and social well-being, but also their level similar metrics to assess cities’ resilience to of “congestion costsâ€? such as pollution, greenhouse climate change impacts. gas emissions, and overcrowding.

Which Cities are Most at Risk from Climate Change? Various in-depth studies over the past decade have assessed the climate- related risks facing individual cities worldwide, and some global assess- ments have provided overviews of urban risk across multiple cities. As each of these reviews uses a different methodology, the results are difï¬?- cult to compare. In addition, some have focused on the risk to resident populations, others on the risk to economic assets. Nevertheless, to gain a broad idea of the cities most at risk, members of the Partnership for BOX 37 Sustainable cities compared the results of multiple global rankings of cities (Annex 12), each conducted according to its own criteria. The top 10 cities appearing in these rankings were: `Dhaka `Kolkata `Beijing `Manila `Chittagong `Mexico City `Istanbul `Mumbai `Jakarta `Shanghai While this list should be considered provisional for the methodological reasons just described, it can help focus the attention of local, national and international policy makers on the urgent need to address risks in these cities. In general the cities considered most at risk are located in Southeast Asia. Among the top 10, the only non-Asian city is Mexico City.

PART III The Role of Institutions and Partnerships Photo: Curt Carnemark/World Bank PART III: THE ROLE OF INSTITUTIONS AND PARTNERSHIPS 99 Governance and Implementation Key Messages ` Strong institutions and partnerships among the public sector, private sector and civil society are needed in order to adopt multi-sectoral policies for sustainable, green urban growth. ` Capacity-building in local governments and enabling policies at the national level are both important to support sustainable cities. ` Public-private partnerships are opening the provision of public services to the private sector. However, the public authority must create the enabling policy environment and a regulatory framework that protects the interests of both citizens and investors. ` Transnational municipal networks allow cities around the world to collaborate on innovative approaches for urban sustainability. Agreements among cities can circumvent deadlocked inter- national policy negotiations. ` Civil society is emerging as a key stakeholder in implementing participatory processes in urban governance. At the same time, information and communications technology is opening vast new horizons for public participation. ` Despite the existence of a wide array of options for making urban systems sustainable—but ideas, tools, and metrics do not create sustainable cities by themselves. The key to changing the situation on the ground is institutions and their interactions (see Box 39). Case Study: Institutions and Adaptation in Louisiana and the Netherlands BOX 39 Louisiana and the Netherlands had very different reactions to local rises in sea level during the 20th century, and the contrast shows the importance of institutions in adapting to the impacts of climate change. In the case of Louisiana, risks were addressed ex post, with levees being reinforced only after disas- ters had occurred. In the Netherlands, on the other hand, the Delta Commission institutionalized risk management by reinforcing the seawalls on a regular basis, among other measures. Thus, the Netherlands’ successful strategy since 1953 is arguably due more to institutions like the Delta Commission than to physical protections such as seawalls.

A next could be to take triangular international partnerships to the city level. ` A number of private sector programs are targeting urban innovation. Cities are seen as important business clients as well as excellent vehicles to promote sustainability. ` In the academic community, the system of urban research and practice needs to be optimized so that academic groups can contribute to a larger whole, and have access to the necessary funding to do so. ` Multilateral institutions are best placed to organize and coordinate stakeholders and their knowledge.

More than 4,000 companies around the world, including 400 of the world’s largest 500 companies, disclose data on greenhouse gas emissions, climate risks, and governance to the Carbon Disclosure Project launched in 2001 (CDP 2012).

The index is available on a country basis and includes both annual and seasonal temperature and precipitation indicators. It combines the number of additional hot, dry, and wet years; hot, dry, and wet summers; and hot, dry, and wet winters, projected over the 2070–2100 period relative to the 1961–1990 period. This suggests that the countries most exposed to future climatic change are Russia, Albania, Turkey, Armenia, and, to a lesser extent, Macedonia and Tajikistan.
