Purpose – Adapting local areas to climate change is a wicked challenge for local administrations. A participatory research is applied to explore how local experience shared by local experts can inform decision and adaptation planning by taking into account local area characteristics and their interrelationships.

Methodology/approach – We turned to local actors, who live or work in the city and who can be seen as urban experts. Their experiential knowledge has given us a better understanding of the characteristics of their communities. These experts are likely to possess a representation that reflects the local territorial sensitivities, which can help us determine how these characteristics might be impacted by climate change.

Findings – A participatory approach bears many benefits such as mobilizing local stakeholders to find collective solutions. It also allows us to focus on common practices in the urban context, which are likely to be altered by changes in mean temperatures, precipitations, etc. It offers the additional benefit of putting into perspective the relations between a variety of urban issues.

Research limitations – A participatory approach means relying on subjective assessments of the possible effects of climate change, which could challenge the relevance of perceived risks and the scope and types of actions taken.

Originality/value of paper – The number of the available adaptation planning processes involving community stakeholders and assessments of these processes is very limited. A participatory process such as the cross-sectoral initiative organized in Québec City can have significant repercussions on local engagement in climate change adaptation. This provides evidence of the potential of deliberation or interaction of territorial actors to improve their understanding of the issues and their adaptive capacity. On a methodological level, the participatory process in itself and the steps to organize it offered a planning frame that can be reproduced.

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).

The Intergovernmental Panel on Climate Change (IPCC) IPCC (2007) projects that greater precipitation intensity and variability will increase the risks of flooding in many areas because of climate change. With climate change already happening, societies worldwide face the parallel challenge of having to adapt to its impacts as a certain degree of climate change is inevitable throughout this century and beyond, even if global mitigation efforts over the next decades prove successful (European Commission, 2007).

Sustainability issues have become crucial to mitigate urban heat islands (UHIs) and reduce the global warming effect. The climate change news is frequently heard lately due to the extreme weather to the extent that the increasing earth’s temperature often causes disaster and loss of property and life. New adaptation needs to new climate context and limits the on-going effects. One of the ways is adopting green roofs on buildings. Implementing sustainable practices such as green roofs will help mitigate this adverse effect in urban areas. Green roofs provide many benefits such as enhancing the aesthetical quality of the built environment, reduce UHIs, reduce energy consumption, improve storm-water attenuation, roof longevity, and reduce noise pollution. However, only a few buildings in Malaysia have considering green roofs as a main green feature element. There is barely number of buildings that have green roof design even though it offers benefits to the community and environment. This chapter has emphasised the types of green roof systems that are potentially suitable in Malaysia climate and obstacles associated with the green roof system. The study found the barriers to implementing green roofs in Malaysia, especially during the stage of building operation in maintaining the green roof system. The survey has been done, which revealed nine factors that hinder the green roof application. This study also highlights the challenges to overcome the barriers of implementing green roofs in Malaysia.

Chaotic growth and climate change have led to increased uncertainty in social-ecological systems, like urban areas, and have lowered their thresholds to withstand shocks, thus increasing their vulnerability. To reduce this effect, the concept of resilience is increasingly being applied in urban governance and planning. Public participation is seen as an attribute, which potentially increases the resilience of social-ecological systems.

What kind of public participation leads to resilience, and how, are questions which this chapter addresses. To answer these questions, this study focused on relevant literature regarding resilience and governance, and investigated the events related to the flooding of the Ramnadi river corridor in Pune, India. The governance structure within the Ramnadi river corridor was then analyzed using a causal loop diagram. By studying its nodes, linkages, and feedbacks, this chapter explores how public participation affects the resilience of the social-ecological system of the Ramnadi river corridor.

Public memory, a minimum sustained level of perpetual participation, and the presence of proactive institutions which can effectuate various levels and types of participation, have emerged as the qualities of public participation which increase the resilience of social-ecological systems. Based on the presence or absence of these qualities, a new typology of public participation is proposed here, namely the binary of continuous public participation versus event-based public participation. This distinction proves to be an effective indicator of whether an instantiation of public participation can lead to resilience. The applicability of this classification for designing interventions for placemaking has also been discussed.

Urbanization is increasing the vulnerability in mega cities, where poor community often squat on low-lying areas, hilly areas, and hazards prone areas (IDNDR, 1999). The built infrastructures and systems are subjected to natural hazards: floods, earthquakes, landslides, cyclones etc. Thus, cities are vulnerable to disasters (IDNDR, 1999). Moreover, cities are also facing environmental risks due to increasing urbanization (Bhatt, Gupta, & Sharma, 1999). The vulnerability can be reduced by incorporating risk management into urban planning (Bhatt et al., 1999). The risk management includes risk analysis, prevention, and preparedness. Traditionally, risk management was seen as separate discipline to mainstream urban planning (Bhatt et al., 1999). The traditional urban planning is often good at making plans (city beautiful plans, land use plans, strategic plans, development plans) and regulatory controls (Hamdi & Goethert, 1997). However, they fail to deliver benefit at the ground. Only few benefits reach the poor, who are often considered as the most vulnerable in the cities. The urban planning can be improved with an alternative: action planning, which is “problem driven, community based, participatory, small in scale, fast, and incremental, with result that is tangible, immediate, and sustainable” (Hamdi & Goethert, 1997). The action planning is often considered relevant in scaling up its outcome from local level to sectoral and national level. This chapter focuses on linking action planning and community-based adaptation. The community can be defined as “a group of people that are directly linked to each other through a common identity, activity or interest” (Jones & Rehman, 2007). The adaptation here is used in context of climate change, which is already happening, and impacts are growing (IPCC, 2001). The community-based adaptation is process oriented and “based on communities’ priorities, needs, knowledge, and capacities, which should empower people to plan for and cope with the impact of climate change” (Reid et al., 2009). This chapter first briefly discusses the action planning process and its challenges. Further, the chapter discusses the action planning in detail. Later the chapter focuses on framework and tools for community-based adaptation. It also discusses few case studies and challenges and issues. Finally, the chapter tries to build a link between action planning and community-based adaptation.

The key concept of ecosystem-based adaptation (EbA) is how to think of ecosystem in daily lifestyles (both in urban and rural areas), and how ecosystem-based adaptation can be a tool to adapt daily lives in changing climatic conditions. Sustainably managing, conserving, and restoring ecosystems so that they continue to provide the services that allow people to adapt to climate change is known as ecosystem-based adaptation. Summarizing the key observations provided in the earlier chapters, this chapter provides the ways of action-oriented ecosystem-based adaptation.

Purpose – This work offers an investigation of the planning and implementation of climate-adaptation and vulnerability-reduction strategies in coastal mega-cities of the Global South, utilizing Kolkata, India, as a case study. This research is designed to identify factors that aid the implementation of climate-centered action in resource-constrained environments of developing countries and provide a set of policy guidelines reflecting best practices.

Methodology/approach – This work draws principally upon analysis of semistructured field interviews conducted in Kolkata, India, during December 2010 and January 2011. The findings are informed by additional data sources as well, including field observations, informal dialogues and meetings, and a review of secondary literature.

Findings – This work identifies several key success factors, including organizational restructuring, resource redistribution, technological innovation, use of external consultants, coupling of climate and development projects, and integration of climate approaches into infrastructure projects.

Research limitations – This research draws upon Kolkata as a case study; thus the work's broader applicability and utility depend on the similarities between the situation in Kolkata and that of other urban areas. As a local study, this work may also offer fewer insights for regional and national policy.

Originality and value – This work fills a timely, unmet need for a greater understanding of climate-adaptation action in the context of cities of the developing world. The extensive use of personal interviews provides unique insights into the minds of planning officials and professionals and draws upon their practical experience to draw lessons for a wide range of similar environments.

Purpose – The vulnerability and adaptive capacities of cities in Latin America have received relatively less attention compared to other regions of the world. This chapter seeks to address these gaps by (a) examining vulnerability to the health impacts from air pollution and temperature, and exploring whether socioeconomic factors between neighborhoods differentiate these risks within the cities of Bogota, Buenos Aires, Mexico City, and Santiago and (b) assessing the capacity of urban populations to perceive and respond to vulnerability and risk.

Design/methodology/approach – Because of the complex nature of vulnerability, we combined a set of quantitative and quantitative methods and data to determine whether and under what conditions the people in these cities are vulnerable (e.g., Time Series Analysis, Generalized Linear Model, and statistical correlations of exposure and human mortality with socioeconomic vulnerability).

Findings – We found high levels of PM10, ozone, and other criteria air pollutants in three cities for which we had data. However, the pattern of their impacts on health depends on the particulars of pollutant levels and atmospheric and weather conditions of each city. Our results reflect the varied facets of urban vulnerability and shed light on the nature of the associated human health risks. Although wealthy populations have access to education, good quality housing, and health services to mitigate some environmental risks, overall the data show that health impacts from air pollution and temperature in the study cities do not necessarily depend on socioeconomic differentiations.

Research limitations/implications – Although we sought to use quantitative and qualitative methods, given the complexity of the research, it has proven difficult to fully explore these issues across scales and with a full accounting of local context.

Practical implications – Our findings show that wealthy and educated populations may be equally at risk to the health implications of air pollution. Policies designed to mitigate these risks should not use socioeconomic characteristics as predictors of a population's risk in relation to air pollution.

Originality/value – This research contributes valuable insights into the dynamics of vulnerability to air pollution in Latin American cities, a region that has been historically underrepresented in empirical studies of urban risk. We have also combined a range of methods and approaches to improve our understanding of the multifaceted nature of urban vulnerability to global environmental change.
