What is the current status of water in India?

India houses 18% of the world’s population but only has 4% of its freshwater resources.

Approximately half of India’s rivers are polluted.

The country’s major reservoirs are at only 38% capacity.

India is the largest user of groundwater globally.

Three-quarters of India’s districts are vulnerable to extreme climate events.

A study by the Council on Energy, Environment and Water (CEEW) revealed that 55% of tehsils in India have experienced a significant increase of over 10% in southwest monsoon rainfall in the last decade compared to the previous three.

What are the impacts of water scarcity on India?

Agricultural Dependency: About 45% of India’s population works in agriculture, which is highly dependent on water for irrigation, influencing crop yields and harvest timing.

Economic Impact: Water scarcity affects the economy, particularly through agriculture, which employs the largest sector of the workforce.

Energy Production: Water is crucial for clean energy solutions like green hydrogen production and pumped storage hydropower, necessary for a sustainable power grid.

Climate Vulnerability: Increased frequency of extreme weather events like floods and droughts disrupts water availability and agriculture.

Urban Stress: Urban areas face challenges like insufficient water for domestic use and industrial activities due to inefficiencies and pollution.

What should be done?

Improve Policy Integration: Develop and implement policies that recognize the interconnections between water, food, and energy systems to manage resources more holistically.

Enhance Water Use Efficiency: Focus on achieving the National Water Mission’s goal to increase water efficiency by 20% by 2025, utilizing water accounting to measure and manage water usage effectively.

Expand Reuse Initiatives: Promote the reuse of urban wastewater as detailed in AMRUT 2.0, reducing non-revenue water and maximizing available resources.

Increase Funding for Adaptation: Boost financial support for water-related climate adaptation, utilizing tools like the Green Credit Programme to fund initiatives that improve water management and promote agricultural resilience.
