Chapter 3 Mapping Climate and Disaster Resilience in Cities

In this chapter the objective is to link the causes (risks) with the need of disaster resilient entities (urban areas) in an era in which the climate is changing and natural hazards are likely to occur more frequently and more severely (Intergovernmental Panel on Climate Change (IPCC), 2007). The previous chapters defined what a resilient city is and how it can be understood, but another question may arise subsequently: how to measure a disaster resilient city? This is what this chapter is about: to develop a tool that is capable of adequately addressing the vulnerable parts of a citys functional system, and additionally, its responsive capacity to cope with a potential disaster. This tool – named Climate Disaster Resilience Index, which is only the process of measurement, or Climate Disaster Resilience Initiative (CDRI), which encompasses all aspects of this approach – shall demonstrate how different functionalities of a city can be assessed in a comprehensive single attempt. Accordingly, the CDRI is more than just a tool to measure the condition of a city at a certain point of time; it also has the wider ambition to lead communities and local governments onto a path of sustainable development that ought to increase the overall resilience level of their city to climate-related disasters. As a result, the CDRI tool shall serve as an urban planning tool depicting the sectors within an urban context that are more or less resilient.

The adoption of a climate disaster resilience index in Chennai, India

Results derived from the Climate Disaster Resilience Index (CDRI)-consisting of five dimensions (economic, institutional, natural, physical, and social), 25 parameters, and 125 variables-reflect the abilities of people and institutions to respond to potential climate-related disasters in Chennai, India. The findings of this assessment, applied in the 10 administrative zones of the city, reveal that communities living in the northern and older parts of Chennai have lower overall resilience as compared to the flourishing areas (vis-à-vis economic growth and population) along the urban fringes. The higher resilience of communities along the urban fringes suggests that urbanisation may not necessarily lead to a deterioration of basic urban services, such as electricity, housing, and water. This indication is confirmed by a strong statistical correlation between physical resilience and population growth in Chennai. The identification of the resilience of different urban areas of Chennai has the potential to support future planning decisions on the citys scheduled expansion.

Action-oriented resilience assessment of communities in Chennai, India

Building resilience to disasters is indispensable in cities, like Chennai, India, which are challenged by emerging urban disaster risks caused by impacts of urbanization and higher probability of future disasters due to climate change. In this paper, an action-oriented resilience assessment (AoRA), consisting of 63 actions, divided into 21 parameters and 5 dimensions (physical, social, economic, institutional and natural), is defined which has the objective to enhance the resilience of communities of Chennai to climate-related disasters. On the basis of responses from the selected target group, community leaders (councillors) in the 155 wards, the local government of Chennai is the key stakeholder to implement the proposed actions in the AoRA. However, further findings underpin that a multi-stakeholder approach, involving communities, academia, private organizations and NGOs, is needed to create disaster resilient communities.

Chapter 9 Partnership Between City Government and Community-Based Disaster Prevention Organizations in Kobe, Japan

The importance of community-based organizations to support relief works in the aftermath of disasters is widely recognized as indispensable in providing quickly the needed help for affected populations (Bajek, Matsuda, & Okada, 2008; Nagasaka, 2008; Norris, Stevens, Pfefferbaum, Wyche, & Pfefferbaum, 2008; Shaw & Goda, 2004; Suzuki, 2006). Although communities’ involvement in rescue operations is essential, their role in rehabilitation and future disaster preparedness activities is equally important in the process of forming a disaster-resilient society (Nagasaka, 2008). Furthermore, the level of interaction between local authorities and communities within different phases (preparedness, relief, and rehabilitation) of the disaster management cycle requires attention to effectively implement community-based disaster risk reduction (CBDRR).

Chapter 9 Climate change adaptation and urban risk management

In the scientific field of climate change adaptation (CCA), the focus on cities has grown steadily in recent years. Increasing population figures especially in developing countries, and overall in cities, demonstrate a key challenge for institutions, communities, economies, and the natural environment to find appropriate solutions to overcome this problem (Intergovernmental Panel on Climate Change [IPCC], 2007). Rapid urbanization is just one of the key issues that cities have to deal with; another main challenge is how to manage the impacts from climate change like increasing numbers of natural hazards that are resulting in more frequent and intense disasters (EM-Dat, 2009; Munich Re Group, 2009).

Chapter 6 Climate and Disaster Resilience Mapping at Microlevel of Cities

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 citys 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).

Chapter 12 Land Use: Urban and Land Use Planning for Disaster Resilience

In this chapter, the linkages between environment- and disaster-related issues are reviewed in the context of urban planning in developing countries. The focus is on urban areas, with the aim to understand processes in urban systems that are distinct from those in rural villages/towns. Over the past few decades, more people have started living in cities in comparison to rural areas. This shift has led to an increase in the global urban population, which became larger than the rural population in 2007 (United Nations Habitat [UNHABITAT], 2008). The majority of this urban growth has taken place in cities located in developing countries, predominantly in the Asian and African region (UNHABITAT, 2008). Furthermore, it is estimated that up to 95 percent of the total global population increase will be in cities (UNDESA, 2010). Mainly cities in low- and mid-income countries are experiencing trends of urbanization (UNHABITAT, 2008). Projections suggest that 8 out of total 29 new megacities by 2025 will be in developing countries (UNDESA, 2010); therefore, the vast amount of growth will take place in many small and medium cities (UNDESA, 2010; United Nations International Strategy for Disaster Reduction [UNISDR], 2009).

Chapter 4 Climate and Disaster Resilience Mapping at National Level

In this chapter, the question posed is how the CDRI, applied at various cities spread across a country like India, can draw implications that are applicable for other cities in this country. The aim is to understand the risks, vulnerabilities, and capacities (resilience) of 12 Indian cities to respond to potential climate-related disasters. Surjan, Sharma, and Shaw (in press) highlight that particularly the Asian region is experiencing rapid urban growth, which is not only leading many cities to become megacities, with a population above 10 million, over the next decades (UN, 2010), but also making many smaller and middle-sized cities experience the phenomenon of urbanization (UNISDR, 2009). As it is perceived that more densely populated areas are at greater risk from potential disasters than the less populated ones, like rural areas/villages, cities require particular attention when it comes to reducing risks (UNISDR, 2009). Unplanned urbanization and poor urban governance are regarded as the two main underlying factors accelerating risk to disasters (UNISDR, 2009). The tool to assess the current condition and resilience of these 12 Indian cities is a contextualized CDRI addressing the Indian characteristics. In an era where climate change–related natural hazards (floods, storms, droughts, etc.) are expected to occur more frequently and with higher intensity (IPCC, 2007), Indian cities are becoming more vulnerable to such events (Revi, 2008).
