Drought Risk Mapping
Definition
Drought Risk Mapping is the GIS-based process of identifying and visualizing regions vulnerable to drought by combining hazard, exposure, and vulnerability data. It integrates historical drought frequency, land use, socio-economic indicators, and adaptive capacity to assess and prioritize areas at risk.
Application
Governments use drought risk maps to guide insurance schemes, prioritize aid, and develop sustainable agriculture policies. Researchers model future drought risk under climate change scenarios. GIS tools support multi-criteria analysis, scenario modeling, and the creation of composite risk indices. Maps highlight at-risk communities and help implement mitigation measures like drought-resistant crops or water storage systems.
