    The Deep Politics of Canal Irrigation in India with Peter Mollinga

    Why do canal irrigation systems repeatedly produce head-tail inequality? Why do some farmers receive reliable water while others are systematically deprived for decades? In this episode, Veena Srinivasan speaks with Professor Peter Mollinga, a leading scholar of irrigation and water governance, about the politics of canal irrigation systems in India. Drawing from nearly 40 years of research on the Tungabhadra Left Bank Canal in Karnataka, the conversation explores the origins of “protective irrigation,” the spread of paddy cultivation, migration and agrarian change, groundwater salinity, farm ponds, irrigation reforms, and the political economy shaping canal systems across India. The episode examines why irrigation systems are never purely technical systems, but social and political systems shaped by power, institutions, incentives, and historical choices.

    California's Groundwater Governance Successes | Dr. Maurice Hall

    California’s groundwater crisis did not emerge overnight. Decades of unrestricted pumping, falling groundwater levels, land subsidence, disappearing streamflows, and recurring droughts eventually pushed the state toward one of the world’s most ambitious groundwater governance reforms: the Sustainable Groundwater Management Act (SGMA). In this episode of the Water Data Podcast, Dr. Maurice Hall, Senior Advisor for Climate Resilient Water Systems at the Environmental Defense Fund, joins host Veena Srinivasan to speak about California’s landmark Sustainable Groundwater Management Act (SGMA). The conversation explores how California’s unique water rights system shaped groundwater use, why the 2012–2016 drought became a turning point, and how local Groundwater Sustainability Agencies are now attempting to balance pumping, recharge, ecosystems, and agricultural demand across the state. Maurice explains the science behind land subsidence, disappearing streamflows, and groundwater depletion, while also unpacking how California invested heavily in groundwater monitoring, basin-scale models, satellite-based evapotranspiration tools like OpenET, and new approaches to managed aquifer recharge. The episode also reflects on what India can learn from California’s experience. While the political and agricultural contexts are very different, the challenges of groundwater depletion, fragmented governance, and delayed action resonate strongly across both regions. This episode offers a rare inside look into the science, politics, and institutional challenges of groundwater governance at scale.

  3. The Hidden Politics of Water Systems | Margreet Zwarteveen

    The Hidden Politics of Water Systems | Margreet Zwarteveen

    Why is water never just a technical problem? Who gets water, who loses access, and who gets to decide? In this episode of the Water Data Podcast, Professor Margreet Zwarteveen, an internationally recognised scholar of water governance, irrigation, gender, and the politics of natural resources, joins host Veena Srinivasan, Executive Director at WELL Labs. Margreet Zwarteveen is Professor of Water Governance Education at IHE Delft and Professor of Governance and Inclusive Development at the University of Amsterdam. Trained first as an irrigation engineer and later as a social scientist, her work has shaped how we understand water as a deeply social and political resource. In this conversation, Margreet explains why every water intervention – whether it is a dam, canal, borewell, drip irrigation system or water market  , all make political choices. Technical designs decide who gets access to water, whose labour is recognised, whose land and water rights matter, and whose knowledge is ignored. The episode explores irrigation resettlement schemes, farmer participation, water titling, gender in irrigation engineering, the risks of narrow efficiency metrics, and the hidden politics behind “wise” water use. Margreet also discusses why women’s water work is often invisible, how borewells and infrastructure reshape water access, and why water governance must learn from everyday practices on the ground.

    How Satellite Tech Imaged the Global Groundwater Crisis | James (Jay) Famiglietti

    How can a satellite measure water buried deep underground? What can space-based observations tell us about groundwater depletion across the world? And how is this data shaping the future of water policy and governance? Professor Jay Famiglietti, a leading hydrologist and former NASA scientist, joins host Veena Srinivasan on this episode of the Water Data Podcast to discuss the revolutionary GRACE satellite mission. Jay is a Global Futures Professor at Arizona State University and is widely known for developing methods to detect groundwater depletion from space. His work has reshaped how scientists and policymakers understand global water systems. In this episode, Jay and Veena unpack how GRACE measures tiny changes in Earth’s gravity to detect gains and losses in water mass. They explore how this technology has revealed major groundwater depletion hotspots across the world, including India, California, the Middle East, and China. The conversation also examines the complex relationship between climate change and human water use, and why these forces are deeply intertwined. Finally, they reflect on how satellite data is influencing policy from drought monitoring systems to groundwater governance and what the future holds for global hydrology.

    The Social Science of Water: Beyond Hydrology ft Trevor Birkenholtz | Water Data Podcast

    What does water have to do with power, caste, labor, and economic policy? In this episode of the Water Data Podcast, Professor Trevor Birkenholtz (Penn State University) explains how political ecology helps us understand groundwater, irrigation, and large-scale water infrastructure in India. Trevor Birkenholtz is a political ecologist and development geographer with regional interests in South Asia and the United States. His empirical interests are in water-supply development, water infrastructure, wetlands and the politics of environmental change. This conversation explores how water systems are shaped not just by engineering, but by power, history, caste, labor, and policy decisions. How do subtle reservoir rule changes dispossess farmers? And why is urban “drinking water” often an industrial demand? This episode is essential listening for researchers, policymakers, and practitioners working at the intersection of water, agriculture, and development.

    Participatory Groundwater Management with Himanshu Kulkarni | The Water Data Podcast

    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.

    Himanshu Kulkarni and Indian Hydrogeology | The Water Data Podcast

    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 1. In this episode, Dr. Kulkarni traces the origins of his groundwater journey – from early memories of the first wells and springs he encountered, to studying geology and being mentored by an exceptional hydrogeology teacher Vilasrao Salunkhe. He then takes us into his landmark field research in Pabal in rural Maharashtra, where detailed well surveys and long-term measurements revealed how basalt aquifers behave, why groundwater availability varies sharply across the same landscape, and how farming decisions around wells, pumps, and crops change when water availability and markets shift together. Along the way, the conversation unpacks key hydrogeology ideas in accessible ways, including layered basalt aquifers, heterogeneity, anisotropy, transmissivity, storage, and why some wells are productive only seasonally while others sustain longer. They also discuss groundwater decline, cropping pattern changes, watershed development, spring revival programmes, community water governance, urban groundwater challenges, and why trust and local knowledge cannot be scaled like physical infrastructure. The episode reflects on groundwater as a shared commons and introduces the broader arc of Dr. Kulkarni’s work – from the watershed movement and the emerging groundwater crisis to the practice-driven approach that later shaped ACWADAM’s capacity building efforts and participatory groundwater management in India.
