    Participatory Groundwater Management with Himanshu Kulkarni

    In this episode of The Water Data Podcast, host Veena Srinivasan speaks with Dr. Himanshu Kulkarni, hydrogeologist and co-founder of ACWADAM, about groundwater science in India – from basalt aquifers and rural irrigation to springshed revival in the Himalayas and participatory groundwater management. This episode was recorded in November 2025 on the sidelines of a two-day event celebrating the life and work of Dr. Himanshu Kulkarni, marking his recognition with the 2025 International Water Prize by the University of Oklahoma. Because the conversation was long and deeply insightful, we’re releasing it in two parts – this is Part 2. In this episode, Dr. Kulkarni explains how participatory groundwater management (PGWM) evolved in India, and why aquifers must be treated as common pool resources. He shares field-based examples of PGWM “models” in practice — from borewell bans and drinking water protection zones to borehole pooling and crop planning. He also reflects on the biggest external forces shaping groundwater outcomes, especially energy policy and market incentives.  Through this conversation, he explains why urban groundwater remains “hidden”, and why cities must treat recharge as a public service, not just an individual mandate. Finally, he highlights the major unanswered questions in groundwater today — contamination and depletion — and why groundwater science will always remain a field science. The Water Data Podcast is a talk show on the science, systems, and stories of water hosted by Veena Srinivasan.  For all references and further readings related to the episode, visit https://welllabs.org/wdp-himanshu-kulkarni-pt2/ Subscribe to The Water Data Podcast on your favourite podcast app – and catch video episodes on the WELL Labs YouTube channel @welllabs.

  2. Maharashtra's Groundwater and Basaltic Aquifers with Vivek Grewal | The WELL Labs Show

    Maharashtra's Groundwater and Basaltic Aquifers with Vivek Grewal | The WELL Labs Show

    Hydrogeologist Vivek Grewal joins host Pavan Srinath to unpack how Maharashtra’s basalt geology shapes groundwater and why managing it requires thinking in layers. The conversation explores how the Deccan Traps were formed, how vesicles, fractures and weathered rock store water, and why groundwater in Maharashtra behaves very differently from granite aquifers in South India. Vivek takes us from mantle plumes and lava flows 65 million years ago to today’s seasonal and perennial aquifers, open wells versus borewells, recharge pits, farm ponds, and the delicate balance between upstream and downstream water security. The conversation also explores how farmers adapt cropping patterns under seasonal water constraints and why cities like Pune must identify and protect recharge zones to secure their future. Vivek Grewal is the managing partner with the Technical Consulting programme at WELL Labs. He has around 9+ years of experience in the water sector. He is passionate about taking the science of hydrology to the grassroots organisations. Pavan Srinath is the Managing Partner for Communications and Development at WELL Labs. Pavan is a communications and public policy professional who has spent over 14 years working in Bangalore's not-for-profit sector. This episode is essential viewing for anyone working on groundwater management, watershed development, agriculture, or urban water planning in peninsular India.

    Running the Odisha Millets Mission with Ashima Chaudhary

    In the fourth episode of The WELL Labs Show, host Pavan Srinath is joined by Ashima Chaudhary (Managing Partner, Rural Futures, WELL Labs) to unpack how millets went from being seen as “poor people’s food” to becoming a serious solution for nutrition, climate resilience, and farmer livelihoods.Ashima previously worked with WASSAN, where she was the State Programme Coordinator for the Odisha Millets Mission. The conversation explores what millets are, how they are commonly classified (major vs minor millets), and why millet cultivation and consumption declined after the Green Revolution, especially due to the missing processing ecosystems and the dominance of rice and wheat in markets and public distribution.Ashima then takes us inside the story of the Odisha Millets Mission: a systems approach that moved production, processing, procurement, and consumption in parallel. She explains how farmer choice was protected in programme design, how incentives were used to support improved agronomic practices, how participatory varietal trials helped identify and strengthen local seed systems, and how procurement linked to PDS and ICDS helped scale demand alongside supply. We also hear about food festivals, recipe innovation, and what it took to make millets desirable again across rural communities and urban audiences.Ashima Chaudhary is the Managing Partner for Rural Futures at WELL Labs. She has spent over a decade at WASSAN (Watershed Support Services and Activities Network -Watershed Support Services and Activities Network - https://wassan.org/ ) working on millet revival across cultivation, value chains, processing ecosystems, and consumption, contributing to large-scale, government-led efforts such as the Odisha Millet Mission.

    South India's Groundwater Explained | Vivek Grewal

    Hydrogeologist Vivek Grewal helps host Pavan Srinath understand the aquifers and the groundwater in South India's hard-rock landscapes. This is a third episode of The WELL Labs Show. The conversation explores why borewells keep getting deeper year after year, why wells dry up by January even after a good monsoon, and what it actually takes to address groundwater challenges in regions with hard rock. Drawing on simple analogies, field experiences from WELL Labs’ technical consulting work across rural South India, and years of hydrological research, Vivek explains what granite and gneiss are and why they matter for groundwater, how water is stored and moves through cracks and fractures in hard rock, and how the borewell revolution fundamentally altered groundwater use. The discussion also examines how traditional tank systems, and recharge processes shape water security, and how WELL Labs approaches diagnosing groundwater problems on the ground before designing interventions. Vivek Grewal is the managing partner with the Technical Consulting programme at WELL Labs. He has around 9+ years of experience in the water sector. He is passionate about taking the science of hydrology to the grassroots organisations. Pavan Srinath is the Managing Partner for Communications and Development at WELL Labs.
