The latter half of the 20th century has seen the rise of local actors in the international milieu. Among these so-called local “internationals” (Alger, 1999) were local governments who have come to assert their role in various aspects of international development. Since the end of World War II, municipalities have actively forged partnerships with other localities in other countries,¹ even to the point of challenging the foreign policies of their own countries in such thorny issues as the apartheid in South Africa, nuclear disarmament, human rights, and the Sandinista war in Nicaragua (Hobbs, 1994; Shuman, 1994; Fry, Radebaugh, & Soldatos, 1989). The importance of municipalities as global players has grown substantially over the years. At the Earth Summit in Rio de Janeiro in 1992, among the major issues highlighted in the Agenda 21 was the need to devote “greater attention to issues of local government and municipal management” (UNEP, n.d., 5.3). It further pointed out that in order for cities, especially those plagued by severe sustainable development problems, to develop along a sustainable path, they should, among others, “participate in international ‘sustainable city networks’ to exchange experiences and mobilize national and international technical and financial support” (UNEP, n.d., 7.20.d) and “reinforce cooperation among themselves” (UNEP, n.d., 7.21). Four years later, at the UN-HABITAT II City Summit in Istanbul, cities were officially recognized by the United Nations as the “closest partners” of national governments for the implementation of the Habitat Agenda (UN-HABITAT, 2003). In 2005, as a demonstration of their commitment to work for the achievement of the Millennium Development Goals (MDGs) on the ground, over one thousand cities and local government associations issued and adopted the Local Government Millennium Declaration at the Millennium+5 Summit in Beijing (UCLG, 2010).

During the period of 2000–2009, a record 402 climate-related disasters occurred in the Southeast Asia region, and the number of geophysical disasters was 61 according to the International Disaster Database by Center for Research on the Epidemiology (CRED). The number of climate-related disasters is much higher than that of geophysical disasters, but due to small or medium scale of the events, attention and assistance to most of them have been limited. Although many people are affected by these disasters every year, in many cases, they do not have sufficient idea and knowledge on preparedness and disaster risk reduction (DRR).

Decision-making is an important step in the risk management process. Decisions often need to be based on incomplete information, and have to carry an element of sound judgment with them. Decision-making is usually a prerogative of government agencies in change of development and disaster management. But it also needs to be included in participatory processes involving citizens – which is far more than mere consent of the public to decisions taken by others.

The most critical components of decision-making are participation and consensus building. In fact these two elements are often in conflict with each other. In the spirit of participation, a wider consultation is needed, and when participation widens, it becomes difficult to arrive at consensus. Simple tools can be very useful in evolving consensus within the planning groups, civil society actors and the government.

The content of this chapter focuses specifically on environmental risk and its potential to exacerbate the negative impacts of a disaster event. It also looks more closely on the built environment and the role that effective decision-making can play in not only mitigating urban risk, but also to preserve/conserve the local environment. They key message of the cyclical interrelationships between good environmental management and reducing disaster risk, lies at the core of this paper.

Metro Manila, composed of 13 cities and 4 municipalities, is the home of more than 11 million people, and is vulnerable to different types of hazards, including earthquakes and flooding. This chapter focuses on the legal and institutional framework of Metro Manila, and analyzes the effectiveness of local governance in reducing the impacts of earthquake risk in the community level. Although most of the cities are faced with different barriers and challenges with regard to institutional and legal aspects, it is required to mobilize communities and utilize appropriate community leadership to enhance actions at the local level. In case of Manila, barangay or the lowest government body plays a key role in implementing risk reduction measures at community levels, and barangay captain (elected local representative) plays a crucial role in facilitating implementation. A combination of public help, mutual help, and self-help will be able to develop risk reduction strategies at local level.

Located at the center of the Red River Delta, Hanoi is the consequence of the unstable balance between soil and water and has witnessed the amicable and adverse relationship between the two elements over a long history. Established as a small town in A.D. 210, Hanoi grew from a harbor on the bank of the Red River to a thriving city and was chosen to be the capital of Vietnam in 1010 as the site had advantageous physical, landscape, and geomancy characteristics. However, the capital had also been confronted with difficulties due to the alluvial process, which raises the level of the watercourse above its normal elevation forcing the inhabitants to take measures such as building a dyke to prevent floods. This chapter analyzes the natural and social conditions as well as several problems that have been affecting urban flood risk management in Hanoi. The chapter ends with practical options and policy measures to address the problems.

Building a resilient city requires detail and careful assessment of its current level of vulnerabilities and resilience. During such assessment and initiatives it should remember that there are large differences in risk and vulnerability within urban areas (Satterthwaite, Dodman, & Bicknell, 2009). It is natural to consider that the vulnerabilities and eventually the resilience level would not be same for all parts of a city, especially one that is relatively larger. A city, especially a large one, covers a substantial and often physiographically heterogeneous area with different exposures and susceptibility to hazards. Furthermore, a city's population and the conditions under which it lives are diverse. Therefore, some parts and peoples of a city may be more vulnerable than others (Klein, Nicholls, & Thomalla, 2004). In fact, cities form different microclimates within them because of the variations of land use, settlement patterns, functions, densities, and characteristics of the residential areas and their communities. All of these diversities contribute to disaster risk; in turn, these affect human development and the resilience of different parts of the city International Strategy for Disaster Reduction (ISDR).

Nishinomiya City in Japan is one of the most successful cities in implementing eco-community and has served as a particularly influential model, especially through programs on Education for Sustainable Development (ESD) which the Japanese Ministry of the Environment recognized as the nationwide environmental education program. Nishinomiya City has been implementing a project, “Environmental Learning City,” where community-based environmental management has been conducted through environmental education programs. And it established an NPO, “the Learning and Ecological Activities Foundation for Children (LEAF),” to facilitate the programs and build partnerships among citizens, businesses, and the local government. As a result, Nishinomiya's eco-community activities have been sustained, and not only environmental improvement but also social cohesion and mutual learning have been achieved.

Climate and disaster resilience mapping has been discussed in detail in Chapter 3. The Climate Disaster Resilience Index (CDRI) as a comprehensive and well-structured methodology for measuring the resilience of cities is presented, as well as the differences between CDRI and various assessment tools. The resilience of cities, or their agglomerations or subzones, is being measured because cities are seen to be at a suitable level to efficiently initiate action, especially in developing countries where unplanned or haphazard urbanization is a major risk factor. But for climate and disaster resilience mapping to be of value, it should be followed by action planning. Having a vision for the future and charting a course to achieve it is what action planning is about. Studies have consistently shown that vision, planning, and goal setting can positively influence cities’ organizational performance. Action planning can compel future thinking, highlight new opportunities and threats, and refocus a city's mission. Productive action planning focuses on the most critical problems, choices, and opportunities. Action planning requires time and a process. If used effectively, it is a powerful tool for self-management and goal-based achievement. Action planning typically includes deciding who is going to do what and by when and in what order for the city to reach its long-term goals. The design and implementation of the action planning depend on the nature and needs of the city.

The notion of social capital refers to social connections between people, such as networking, trust, norms, etc. Rich and good-condition social capital is supposed to enhance collective action in a society. This is why social capital has attracted more attention in the field of development studies and environmental management studies in recent years. However, the forms and conditions of social capital are different in each society and there is no ideal social capital. Therefore, it is important to know the advantages and disadvantages of the original social capital and how it can be supplemented. In the environmental learning project in Danang, Central Vietnam, social capital was fostered through the activities of the residents' group. New and strong networks of people have been created among broader neighborhoods. The residents' group created multidimensional networks (bridges) in the society and helped to foster social capital. Eventually, the residents' group is expected to bring success to the participatory urban environmental project by fostering social capital in the local society.

Capacity development (or capacity building, capacity enhancement) is becoming an increasingly important component in development assistance through agreements among multilateral and bilateral donors and developing countries because it is critical for achieving development objectives. Much evidence has indicated that development assistance and projects have not been successful due to capacity constraints; therefore, many training programs for capacity development were implemented and continue to be in demand at various levels.
