The WELL Labs Show

Watershed researcher Karan Misquitta  joins host Pavan Srinath to unpack how water conservation, labour, and technology have shaped India’s landscapes over more than a century.This episode explores the evolution of watershed development — from colonial-era famine relief works to modern-day machine-led interventions. Karan explains how droughts historically led to labour-based public works, why soil and water conservation became central to rural employment programmes, and how structures like bunds, trenches, percolation tanks, and check dams transformed agricultural landscapes across India.The conversation also examines a critical tension: how do we balance creating employment at scale with building effective, durable water systems? Drawing on his research in Maharashtra, Karan traces the shift from labour-intensive watershed programmes to capital-intensive approaches driven by excavators, farm ponds, and large-scale recharge efforts — and what this means for groundwater, farmers, and policy today.Karan Misquitta is a Senior Researcher at WELL Labs, with a PhD in Geography. His work focuses on groundwater, rural water systems, and the political economy of watershed development in India.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 water conservation, rural development, agriculture, public policy, or employment programmes — and for those trying to understand how India’s water landscapes have been shaped by both people and machines.The WELL Labs Show features rich conversations on water, environment, land and livelihoods, from the people and partners of WELL Labs.

Hydrogeologist Vivek Grewal (https://www.linkedin.com/in/viveksinghgrewal/)  joins host Pavan Srinath (https://www.linkedin.com/in/pavansrinath/?originalSubdomain=in)  once again to unpack the basic science of groundwater and to explain how groundwater behaves in one of India’s most important hydrogeological regions.Where does groundwater fit in the water story? Vivek explains why most of the world’s liquid freshwater exists underground, how rainfall becomes groundwater, and how rivers like the Ganga are sustained by flows beneath the surface.The episode then breaks down how aquifers work from porosity and fractures to recharge and baseflow - while debunking common myths about “hidden underground rivers.”Finally, the discussion turns to the Indo-Gangetic aquifer, explaining how it was formed and why regions like Punjab, UP, Bihar and Bengal face very different challenges - from depletion and salinity to arsenic contamination.Drawing from both field experience and hydrogeological research, Vivek also explains why western India faces severe depletion despite large underground storage, why eastern India may have more water but different access and quality challenges, and how a better understanding of groundwater is essential for managing agriculture, drinking water and long-term water security.Vivek Grewal (https://welllabs.org/vivek-singh-grewal/ ) is the Managing Partner with the Technical Consulting programme at WELL Labs. He has around 9+ years of experience in the water sector.

Veena Srinivasan and Gayathri Muraleedharan join host Pavan Srinath on this episode of The WELL Labs Show to unpack the nature of Bangalore’s water crisis — what caused the severe summer crisis of 2024, why similar crises may recur, and what the city can do to avoid lurching from one groundwater emergency to the next.The conversation explores why Bangalore’s water crisis is not a “Day Zero” reservoir crisis like Cape Town or Chennai, but fundamentally a groundwater crisis. Veena and Gayathri explain how the city depends on both Cauvery water and groundwater, why the most acute pain is felt in newly developed peri-urban areas and dense apartment clusters, and how Bangalore’s hard-rock aquifers, uneven topography, and hyperlocal recharge patterns make the problem difficult to predict and manage.Drawing on WELL Labs’ work on urban water balances, groundwater dependence, wastewater treatment, and water reuse, the discussion examines how much water Bangalore needs, how much it receives from the Cauvery, and how much is being invisibly supplied through private borewells and tanker systems. They also explore why treated wastewater reuse, especially through decentralised sewage treatment plants in apartments and commercial complexes, may be one of the most practical ways to reduce pressure on the city’s fragile aquifers.The episode also reflects on what has changed since the 2024 crisis: greater seriousness around water reuse, more interest from apartment communities in running STPs efficiently, efforts by BWSSB such as the Green Star Challenge, and the need for stronger incentives, better monitoring, groundwater recharge, sponge landscapes, and more realistic water pricing. The conversation ends with a hopeful but grounded argument: that while Bangalore’s water crisis is systemic, the city also has many solutions that can be acted upon locally — by institutions, neighbourhoods, apartments, and public agencies alike.Veena Srinivasan (https://welllabs.org/veena-srinivasan/)  is leading WELL Labs’ mission to transform scientific research into real-world impact by designing solutions that simultaneously create livelihoods and conserve the environment.

In this episode of The WELL Labs Show, John Thompson , a leading researcher in development studies and sustainability, joins the host Arjuna Srinidhi,  to unpack the idea of “Pathways Approaches” and what it means for building climate resilience in complex systems.The conversation explores how dominant development pathways in agriculture, water systems, or food systems often become locked in through policy, markets, and institutional incentives. John explains how the Pathways Approach helps researchers and decision-makers move beyond these lock-ins by opening up multiple possible futures and examining who benefits, who loses, and what trade-offs different choices create.Drawing on examples from food systems in Africa and ongoing work under the CLARITY, John discusses how diversification, experimentation, and stakeholder dialogue can help societies navigate uncertainty. The discussion also explores the idea of Transformation Labs, where researchers, communities, and policymakers co-design research, co-produce knowledge, and jointly explore pathways toward more equitable and climate-resilient futures.John also reflects on how researchers can make decision-making processes more transparent and accountable — not by prescribing solutions, but by helping societies understand the consequences of different development choices.CLimate Adaptation and Resilience In Tropical drYlands (CLARITY) addresses the critical need to identify equitable, sustainable and climate-resilient development pathways in tropical drylands. This Global South-led project will result in the creation of long-term assets (data and tools) and capacities to achieve transformational change.The WELL Labs Show features rich conversations on water, environment, land and livelihoods, from the people and partners of WELL Labs.

In this episode, Bruce Currie-Alder from the International Development Research Centre (IDRC), Canada, joins host Veena Srinivasan to unpack the vision behind the CLARE (Climate Adaptation and Resilience) programme – a global initiative supporting action-oriented climate adaptation research across Africa and Asia.As climate change unfolds in real time, Bruce argues that research can no longer operate at a distance from action. Instead, it must be embedded within development processes, communities, and institutions – shaping decisions from the next climate shock to the next two decades.The conversation explores why adaptation is no longer a future problem, the tension between short project timelines and long-term transformation, what “development under a changing climate” really means, gender equity and social inclusion in climate research, and the need to build the next generation of climate problem-solvers.Bruce reflects on what success would look like 20 years from now — not only in terms of project outcomes, but in the people and partnerships that continue solving problems long after the programme ends.CLARE (Climate Adaptation and Resilience) (https://clareprogramme.org/) is a global research programme funded by Canada’s International Development Research Centre (IDRC) and the UK’s Foreign, Commonwealth & Development Office (FCDO).

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.Pavan Srinath⁠ is the Managing Partner for Communications and Development at WELL Labs.

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.
