Hydroclimate extremes mind map with below nodes
Context
Study at Banaras Hindu University
Examines global warming impact
On hydroclimate extremes
Over Indian River Basins (IRBs)
Source: PIB
Hydroclimatic extremes definition
Extreme events
Impact on human societies and ecosystems
Events include
Floods
Droughts
Heatwaves
Rainstorms
Study methodology
Used high-resolution simulated precipitation data
From Coupled Model Intercomparison Project-6 (CMIP6) experiments
Findings
Frequency of extreme rainfall expected to increase
Over Western Ghats
Over Northeast River basins
Heavy rainfall intensity projected to increase
Over Upper Ganga
Over Indus basins
Agricultural drought in lower Ganga basin
Due to decline in mean rainfall
Significance
Need for policymakers to develop strategies
To manage water surplus or scarcity
Predicts 4% to 10% increase in heavy rainfall
Over western part of Indian River basins
Significant precipitation changes in specific areas
Changes in hydroclimate extremes could impact
Agriculture
Health
Socio-economic conditions
Identifies major hotspots for future urban flooding
In highly populated cities
Suggests policymakers should design basin-specific climate adaptation and mitigation strategies
Including water and emergency services policies
To minimize risk associated with extreme events in these basins
