Climate change risk: an adaptation and mitigation agenda for Indian cities

This paper considers the needed adaptation and mitigation agenda for cities in India — where the urban population is likely to grow by around 500 million over the next 50 years. It considers the likely changes that climate change will bring in temperature, precipitation and extreme rainfall, drought, river and inland flooding, storms/storm surges/coastal flooding, sea-level rise and environmental health risks, and who within urban populations are most at risk. It notes the importance for urban areas of an effective rural adaptation agenda — especially in maintaining the productivity and functioning of rural systems. It highlights the importance of today's infrastructure investments, taking into account climate changes, given the long lifespan of most infrastructure, and the importance of urban management engaging with changing risk profiles. One important part of this is the need to connect official adaptation initiatives to the much-improved natural hazard risk assessment, management and mitigation capacity that responded to major disasters. The paper ends by describing a possible urban climate change adaptation framework, including changes needed at the national, state, city and neighbourhood levels, and linkages to mitigation.
