How Can We Measure Water Security Accurately?

This learning note explores the need for a framework like WISER (Water Index for Sustainability, Equity, and Resilience)—a science-based approach to tracking and enhancing water security in India. WISER leverages data, remote sensing, and stakeholder engagement to support evidence-based, equitable, and sustainable water management.

India’s water crisis—driven by overuse, pollution, and climate change—demands better outcome-based tracking despite large investments in water management.

WISER (Water Index for Sustainability, Equity, and Resilience) offers a science-based framework to measure water security across six dimensions using data, remote sensing, and stakeholder input. It aims to inform policy, improve resource use, and enable sustainable, equitable water management.

This learning note is the first in a two-part series capturing the findings from Phase 1 (July 2024–March 2025) of the Water Index for Sustainability, Equity, and Resilience (WISER) initiative. It includes key learnings from stakeholder interviews, listening circles, feedback sessions, and a roundtable discussion. We also conducted a literature review to develop a framework of indicators to assess water security and tested them through a pilot survey across five different aquifer typologies. Part 2 of this series summarises the literature review and the pilot study results.
