Disaster Risk Mapping: A Desk Review of Global Best Practices and Evidence for South Asia

The frequency, intensity, and variability of natural hazards are increasing with climate change. Detailed sub-national information on disaster risks associated with individual and multi-hazards enables better spatial targeting of adaptation and mitigation measures. This paper reviews the global best...
