Read Original ArticleKey Points
The World Bank report highlights the misalignment in global food systems, impacting food security, aggravated by energy shocks, particularly in India's unsustainable agricultural practices. This is crucial for UPSC aspirants, especially for GS Paper 3, which covers economic development and environmental issues. Last Updated: 06-05-2026
Key Facts About Water-Energy-Food (WEF) Nexus
- The WEF nexus refers to the interconnected nature of water, energy, and food systems.
- Agriculture consumes over 85% of India's freshwater, mostly from groundwater.
- Agricultural pumping uses nearly 20% of India's total electricity.
- State policies offering free or subsidized electricity encourage over-extraction of groundwater.
- The Dynamic Ground Water Resource Assessment Report 2025 categorizes several states as highly over-exploited.
- India spends over Rs 1.5 lakh crore annually on electricity subsidies for agriculture.
- India imports 85-90% of its crude oil, affecting agriculture due to energy dependence.
- India exports significant amounts of "virtual water" through rice and sugar exports.
India's Water-Energy-Food Nexus Challenges
The Water-Energy-Food (WEF) nexus is critical for India's economic and environmental sustainability. The interconnectedness of these resources affects India's strategic goals, including food security and energy independence. The World Bank estimates inefficiencies in current systems could limit sustainable food production by 2050, affecting global rankings and comparisons.
UPSC Relevance
- GS Paper 1: Geography - Water resources and agriculture.
- GS Paper 2: Governance - Policy impacts on resource management.
- GS Paper 3: Economic Development - Energy security and agricultural practices.
- Prelims: Questions on WEF nexus definitions and statistics.
- Mains: Analytical themes on sustainable agriculture and resource management.
FAQ Section
- What is the Water-Energy-Food (WEF) Nexus? The WEF nexus refers to the interconnectedness of water, energy, and food systems, highlighting how each resource impacts the others.
- Why is the WEF Nexus important? It is crucial for sustainable development, ensuring that the use of one resource does not compromise the availability of others.
- What are the key features of India's WEF Nexus challenges? Key challenges include groundwater depletion, energy dependence, and policy-driven imbalances that affect sustainable agricultural practices.
