Phase IFoundation

Background

Overview

Central to GS1 (Physical Geography, Climate Change), GS3 (Disaster Management, Environmental Degradation, Climate Change), and understanding India's vulnerability and adaptation strategies in the face of changing climate patterns.

Hydro-meteorological disasters are natural hazards caused by extreme meteorological and hydrological events, such as heavy rainfall, floods, droughts, cyclones, and heatwaves. These events are increasingly influenced by climate change, leading to higher frequency and intensity, posing significant challenges to disaster management and sustainable development.
