Written by former director of India's National Remote Sensing Agency, D. P. Rao, this article reviews the role of space technology in disaster mitigation.

Rao offers examples of how remote sensing can feed into prevention, preparedness and relief strategies for a number of disasters. He identifies the areas where these applications are operational, and those that need more research and development.

For drought, cyclones, floods, fires, earthquakes and other disasters in India, Rao outlines the status of relevant remote sensing projects. He outlines the extent of the problem posed by each disaster, and how Indian government and nongovernment organisations use remote sensing to improve risk assessment and early warning.

This paper, prepared for the Global Urban Summit, proposes a framework for building climate change adaptation and mitigation measures into India's urban renewal programmes. This involves multiple government stakeholders at national, state and city levels.

The author begins with a description of the urbanisation trends in India and outlines the climate risks facing the subcontinent, including changing rainfall patterns and the potential for more drought, flooding and extreme weather events like cyclones.

The author outlines the vulnerability of urban populations and suggests that reducing it requires a public policy shift towards mainstreaming climate change risk assessment, adaptation and mitigation measures into ongoing national hazard mitigation programmes, and linking them to urban renewal in the largest cities.

Specific measures highlighted by the author include making building data public, building flood defences, strengthening existing infrastructure to withstand disasters and relocating highly vulnerable populations.
