Introduction to the World Bank’s Flagship Report

In April 2024, the World Bank released its flagship report titled “Nourish and Flourish: Water Solutions to Feed 10 Billion People on a Livable Planet”. The report addresses the critical challenge of ensuring global food security amid escalating water scarcity risks, with the world population projected to reach 10 billion by 2050 (UN DESA, 2019). It underscores the imperative of sustainable water management in agriculture, which consumes approximately 80% of global freshwater withdrawals, to meet food demand without degrading planetary health.

Water Use in Agriculture and Economic Stakes

Agriculture dominates global water use, accounting for nearly 80% of freshwater withdrawals (World Bank, 2024). In India, the irrigation sector consumes about 90% of total water use (Central Water Commission, 2023), yet irrigation efficiency stands at a low 38%, well below the global average of 60%. The World Bank estimates a $1.7 trillion global investment gap in water infrastructure to meet food demand by 2050. Failure to address water scarcity could reduce global GDP by up to 6% by mid-century, with South Asia facing potential crop yield declines of 20% due to water stress (IPCC, 2023).

• India’s Jal Shakti Ministry budget allocation for 2023-24 increased by 15% to ₹8,000 crore, reflecting policy prioritization of water resource management (Union Budget 2023-24).
• Efficient water use in agriculture can boost crop yields by 20-30% (FAO, 2023).
• Groundwater depletion remains a critical concern due to inefficient water use and lack of integrated policies.

Legal and Constitutional Framework in India

Article 48A of the Indian Constitution directs the State to protect and improve the environment, explicitly including water resources. The Water (Prevention and Control of Pollution) Act, 1974 (amended 1988) regulates water pollution through Sections 3 and 5, while the Environment Protection Act, 1986 empowers the central government to take measures for environmental protection, including water resources (Sections 3 and 6). The National Water Policy 2012 provides a framework for sustainable water management, emphasizing demand management, conservation, and equitable water allocation.

• Despite legal frameworks, enforcement gaps and fragmented institutional responsibilities hinder integrated water-agriculture management.
• Water pricing and subsidy reforms remain underutilized tools for incentivizing efficient water use.
• Coordination between the Ministry of Jal Shakti and agricultural ministries is essential for policy coherence.

Institutional Roles and Research Contributions

The World Bank leads global financing and research on water-agriculture sustainability. The Food and Agriculture Organization (FAO) sets international guidelines on water use efficiency in agriculture. In India, the Central Water Commission (CWC) is the apex technical body for water resource management, while the Ministry of Jal Shakti formulates and implements water policies. The International Water Management Institute (IWMI) conducts research on water use efficiency and policy reforms. NITI Aayog advises the government on water and agriculture reforms, promoting integrated approaches.

• India’s irrigation efficiency (38%) lags behind global best practices such as Israel’s (>90%) drip irrigation systems.
• Research emphasizes the need for integrating water pricing, subsidy rationalization, and conservation incentives.
• International cooperation and knowledge transfer are critical for scaling sustainable water technologies.

Comparative Analysis: India vs Israel on Water Use Efficiency

Critical Policy Gaps in Water and Agriculture Nexus

Many countries, including India, lack integrated water-agriculture policies that align water pricing, subsidies, and conservation incentives. This misalignment leads to inefficient water use, over-extraction of groundwater, and environmental degradation. The absence of robust data systems and institutional coordination exacerbates these challenges. Moreover, climate change intensifies water stress, demanding adaptive policy frameworks that integrate water resource management with agricultural productivity goals.

• Fragmented governance between water and agriculture ministries impedes holistic solutions.
• Subsidies often encourage water-intensive crops and practices, undermining sustainability.
• Insufficient investment in water infrastructure and technology adoption limits efficiency gains.

Significance and Way Forward

Sustainable water management is indispensable for achieving global food security for 10 billion people by 2050. Policy reforms must integrate water pricing, subsidy rationalization, and conservation incentives to optimize water use in agriculture. Investments in modern irrigation technologies, data-driven water management, and capacity building are critical. India’s experience can improve by adopting lessons from countries like Israel, enhancing institutional coordination, and increasing budgetary allocations for water infrastructure.

• Implement integrated water-agriculture policies to align incentives and resource use.
• Scale up micro-irrigation and water-saving technologies nationwide.
• Strengthen enforcement of water pollution and resource management laws.
• Enhance data collection and monitoring for adaptive water governance.
• Mobilize public and private investments to bridge the $1.7 trillion global water infrastructure gap.
