Introduction
India is facing a severe water crisis, with rapidly depleting groundwater levels, inefficient irrigation, poor wastewater management, and increasing demand due to urbanisation and population growth. In stark contrast, Israel, a country with arid geography and scarce freshwater resources, has emerged as a global leader in water management. Despite receiving just about 200 mm of rainfall annually and being over 60% desert, Israel not only meets domestic and agricultural water demands but also exports water technology globally.
India, with its vast scale and diverse water challenges, can draw critical lessons from Israel’s innovation-driven, policy-backed, and community-engaged water management model.
1. Emphasis on Water Efficiency in Agriculture
Israel’s Approach:
- Israel revolutionised agriculture with drip irrigation, pioneered by Netafim, which delivers water directly to plant roots, reducing loss due to evaporation and runoff.
- Over 75% of Israeli agriculture uses micro-irrigation systems.
- Crops are selected and genetically adapted based on water availability and soil suitability.
What India Can Learn:
- Promote and subsidise micro-irrigation systems beyond high-value crops.
- Replace water-intensive crops (like paddy and sugarcane in water-stressed areas) with climate-appropriate crops.
- Improve extension services to support farmers in transitioning to water-efficient practices.
2. Wastewater Recycling and Reuse
Israel’s Approach:
- Israel treats and recycles over 85% of its wastewater, the highest rate in the world.
- Treated wastewater is primarily used for agriculture, meeting about 50% of irrigation demand.
- Wastewater is treated to high standards via decentralised and centralised plants.
What India Can Learn:
- Develop infrastructure for wastewater treatment and reuse, especially in urban and peri-urban areas.
- Make reuse of treated water mandatory for non-potable applications such as construction, landscaping, and industrial cooling.
- Strengthen legal frameworks and incentivise public-private partnerships (PPPs) in wastewater management.
3. Desalination for Urban Supply
Israel’s Approach:
- Nearly 60% of Israel’s domestic water comes from sea water desalination using reverse osmosis (RO) technology.
- Plants are energy-efficient, government-supported, and operated via PPP models.
What India Can Learn:
- Invest in desalination plants along coastal regions, especially in Tamil Nadu, Gujarat, Maharashtra, and Andhra Pradesh.
- Develop cost-effective and renewable-energy-based desalination technologies for long-term sustainability.
- Use desalinated water selectively, prioritising high-density urban regions with limited freshwater access.
4. Centralised Water Governance and Regulation
Israel’s Approach:
- Water is treated as a national resource governed by the Israel Water Authority, ensuring equitable distribution.
- Real-time data on water usage, rainfall, reservoir levels, and groundwater is collected and analysed for efficient planning.
- Water pricing is structured to reflect scarcity and encourage conservation.
What India Can Learn:
- Strengthen central and state water data systems with digital integration (IoT, satellite mapping).
- Empower a central nodal body like the National Water Mission with regulatory oversight and coordination powers.
- Implement tiered water pricing for urban and industrial users to curb wastage and recover costs.
5. Public Awareness and Cultural Ethos of Conservation
Israel’s Approach:
- Water conservation is ingrained in the national culture through education, awareness campaigns, and even military training modules.
- Every citizen understands the value of water as a strategic and national asset.
What India Can Learn:
- Launch a national water literacy movement, including water budgeting at household and community levels.
- Include water education in school curriculums and civil services training.
- Celebrate successful local water conservation models to build momentum and pride.
Conclusion
Israel’s success in managing its water scarcity lies not in its resources, but in its resilience, technology, and governance. India, with its scale and challenges, cannot copy-paste this model, but it can adapt its core principles—efficiency, reuse, innovation, pricing, and awareness.
For a water-secure future, India must act decisively to integrate technology, community participation, and policy reforms, treating water not as an unlimited resource, but as a shared, strategic asset.
