    Dr Himanshu Kulkarni: Aquifers, Communities and the Path to Sustainability

    Groundwater is one of India’s most important natural resources and one of its least visible. On this episode of Grassroots Nation, we speak with Dr. Himanshu Kulkarni, Co-founder and Director of ACWADAM — the Advanced Centre for Water Resources Development and Management in Pune— about a lifetime spent understanding groundwater. Dr Kulkarni is one of India's foremost hydrogeologists. Over more than four decades, his work has taken him from scientific research and academia into villages and communities across India, where he has worked to understand aquifers not simply as geological formations, but as shared natural systems that have to be understood and managed collectively. At the heart of his work is a powerful idea: when it comes to common resources like groundwater, knowledge has to reach the people who depend on the resource every day. Through ACWADAM, Dr. Kulkarni has worked with communities to map and understand their aquifers, and develop locally grounded approaches to managing water. His work sits at the intersection of hydrogeology, community action and public policy, by bringing scientific knowledge into conversation with the lived experience. In 2025, Dr. Kulkarni became the first recipient from the Indian subcontinent of the biennial International Water Prize, awarded by the Water Center at the University of Oklahoma, an international recognition of his life's work. In this conversation, we talk about aquifers, groundwater, water equity and sustainability. What does decades of working with communities teach us about natural resources? What can science learn from local knowledge? And can a deeper understanding of the water beneath our feet help us build a more sustainable and equitable water future? In this episode, Dr. Himanshu Kulkarni is in conversation with Uma Aslekar, a senior scientist who has been working with ACWADAM since 2002. This interview was recorded in Pune at the ACWADAM office.

    Sunita Narain: Reflecting on four decades of environmental work

    Sunita Narain, Director General of the Centre for Science and Environment (CSE), sits down for a conversation about India’s environmental journey, the politics of pollution, and the fight for a more just and sustainable future through the work of the CSE. For over four decades, Sunita Narain has been one of India’s most influential environmental voices. Joining CSE in 1982 under its founder, the late Anil Aggarwal, she co-edited the landmark first State of India’s Environment report in 1985 and has since worked at the forefront of debates around air pollution, climate change, water, sustainable mobility, and the rights of communities affected by environmental degradation. Her approach has consistently connected environmental protection with the needs of India’s poor and marginalised. Sunita Narain is in conversation with Anumita Roychowdhury, the Executive Director at CSE. She has led some of CSE’s most significant campaigns on clean air and sustainable mobility, including the Right to Clean Air campaign, which helped drive stronger vehicle-emission standards and Delhi’s transition to CNG public transport. Together, they reflect on the evolution of India’s environmental movement, what has changed and what hasn’t and why science, public action, and grassroots mobilisation remain essential to environmental justice. This episode was recorded at the Centre for Science and Environment in Delhi. Grassroots Nation is a podcast from Rohini Nilekani Philanthropies.
