Question

PocketIAS · Accepted Answer

Introduction

Heatwaves are becoming more frequent and intense due to climate change, posing multidimensional risks to health, water security, agriculture, and power systems.
In India, rising temperatures combined with urbanisation and groundwater stress amplify vulnerability, making proactive state intervention essential.

Role of Government in Managing Heatwave Risks

Formulation and implementation of Heat Action Plans (HAPs) at national, State, and city levels.
Early warning systems through IMD and dissemination via digital and local governance networks.
Public health preparedness, including cooling centres, emergency medical response, and awareness campaigns.
Regulation of working hours for outdoor labour under labour welfare frameworks.
Urban planning measures such as cool roofs, green cover expansion, and heat-resilient infrastructure.
Strengthening disaster management mechanisms under NDMA guidelines.

Challenges in Water and Power Stability

Surge in electricity demand due to cooling needs, straining thermal and hydro capacity.
Reduced water availability as reservoirs shrink and groundwater depletes.
Thermal power plants facing efficiency losses and cooling water shortages.
Urban–rural competition for scarce water resources.

Integrated Approaches for Water and Power Stability

Diversification of energy mix toward solar and wind, which align with peak daytime demand.
Decentralised renewable energy and rooftop solar to reduce grid stress.
Smart grids and demand-side management, including time-of-day tariffs.
Promotion of energy-efficient appliances and passive cooling architecture.
Integrated water resource management linking river basins, reservoirs, and urban supply.
Wastewater recycling and rainwater harvesting to augment supply.
Climate-resilient infrastructure planning through coordinated action between power, water, and urban ministries.
Data-driven forecasting models integrating meteorological and utility demand projections.

Conclusion

Managing heatwave risks requires a whole-of-government and whole-of-society approach.
Integrated planning that synchronises climate adaptation, water governance, and energy security is crucial to ensure resilience during extreme weather events.
