8. Integrating Climate Change in City Planning: Framework and Case Studies

The relationship between cities and climate change has been under discussion by researchers and policy makers. It is an accepted fact that cities have a very important role to play in mitigating greenhouse gas emissions. This is especially true for rapidly growing cities in developing countries like India where urban population growth, spatial expansion, and economic development have resulted in increasing demand for energy. Future per capita CO₂ emissions are expected to increase by four times between now and 2050. At the same time, like many other cities in developing countries, Indian cities are experiencing simultaneous challenges including infrastructure scarcity, air quality deterioration, and inadequate water resources. Large populations, high densities, presence of informal settlements, and industries within these cities have made them vulnerable to climate extremes. Urban infrastructure also will be at risk from climate change events including intense precipitation, flooding, and heat events. Future growth in urban areas will exacerbate existing issues of infrastructure provision and environmental issues of air quality, water, and waste. Climate change will be an added dimension to these urban challenges. Current urban planning process does not mainstream climate concerns and therefore necessitates the search for alternate approaches. Using case studies of selected cities, the chapter briefly highlights mitigation and adaptation challenges for these selected Indian cities and suggests a framework for integrating climate change concerns in urban planning and management.
