India pushes water harvesting drive amid rising demand, highlights schemes and gaps

As India intensifies efforts to tackle water scarcity, the government’s push for large-scale water harvesting has brought renewed focus on its significance, implementation, and persistent challenges.

Water harvesting, seen as a critical tool for conserving rainwater and recharging groundwater, has gained prominence due to increasing pressure on the country’s water resources. Experts note that the practice not only ensures water availability during dry seasons but also reduces dependence on erratic monsoons, supports agriculture, and mitigates urban flooding.

The need for such measures has grown in recent years, driven by rapid urbanisation, population growth, and climate variability. Declining groundwater levels across several states and unpredictable rainfall patterns have heightened concerns over long-term water security. Rural regions remain particularly vulnerable due to their reliance on rain-fed agriculture, while cities face rising demand and supply constraints.

In response, the Centre has rolled out multiple initiatives aimed at strengthening water conservation. Key among them are the Jal Sanchay Abhiyan, which promotes construction of water harvesting structures, and the Amrit Sarovar Abhiyan, focused on creating and rejuvenating lakes nationwide. Other major programmes include the Jal Shakti Abhiyan, the Atal Bhujal Yojana, and the Jal Jeevan Mission, all of which incorporate rainwater harvesting and groundwater recharge components. Additionally, schemes such as MGNREGA and Pradhan Mantri Krishi Sinchai Yojana have contributed to building water conservation infrastructure at the grassroots level.

Despite these efforts, implementation challenges persist. Many structures face issues such as poor maintenance and siltation, which reduce their effectiveness over time. Variations in execution across states, coupled with gaps in monitoring and coordination, have also limited outcomes in some regions. Experts point out that inadequate scientific planning in certain projects has resulted in suboptimal groundwater recharge.

Urban areas continue to struggle with limited space and weak enforcement of rainwater harvesting regulations. At the same time, inconsistent public participation remains a concern, affecting the long-term sustainability of conservation efforts.

Analysts emphasise that while government schemes have significantly expanded water harvesting infrastructure, sustained community involvement, improved maintenance, and better planning will be crucial to ensuring durable impact as India confronts growing water challenges.
