Why water governance needs better community feedback. The first blog in this three-part series explores why lived experience should be at the heart of designing and improving water interventions in India. "The check dam was working initially, but two years back, a road was constructed near it and now water doesn't reach there," said Ward Panch Bhanwar Lal*, an elected representative on a village council in Rajasthan, India. Such insights from people who interact daily with water infrastructure rarely travel beyond the village boundary. Yet they often explain why well-intentioned projects falter. In water programs, where success depends on sustained community engagement, local experiences do not always reach those designing or adapting interventions. To make these experiences visible, IWMI need to rethink how feedback moves. Can artificial intelligence help complete the feedback loop? To test how this could be addressed differently in India, the International Water Management Institute (IWMI) partnered with the Centre for Microfinance (CmF); Colectiv, a UK-based tech start-up; and Institute of Development Studies (IDS) on an artificial intelligence (AI) -assisted feedback pilot in Rajasthan. The pilot was embedded in CmF's community-led water security program and focused on how water security planning works in practice at village level. Respondents to the pilot survey included CmF frontline workers, Pani Mitras and Panchayat leaders. Pani Mitras are community volunteers who promote water-saving practices and move village water plans through local governance systems, while Panchayat leaders are local government representatives involved in approving and implementing these plans. These participants answered questions through a WhatsApp-based AI interviewer using text or voice notes. The AI process was designed to anonymise responses during analysis and reporting, group feedback into themes, and share findings with communities and implementers. The aim was not only to collect information faster, but to see whether local experiences could inform program learning. IWMI's research "Voices from the Commons: integrating effective community participation in the policy process in India and beyond" highlighted that community participation is often recognised in policy but weakly built into decision-making. Local experiences rarely travel upward through regular feedback loops that help institutions understand and respond with accountability. Implementers often report what is easiest to count: beneficiaries reached, people trained, infrastructure built, or plans approved. These numbers matter, but they rarely explain why people participate, why volunteers disengage, why approvals stall, or why a water structure stops serving its purpose. Without this qualitative understanding, programs risk mistaking delivery for effectiveness. The wicked problem of participation. Water governance is rarely linear. Technical, social, economic and political factors all shape whether interventions work. Villages are not socially uniform spaces either. In India, caste, class, religion, gender, land ownership and literacy can influence participation. This creates a two-way information problem. Communities often know why plans work or fail, but this knowledge does not always reach program or policy decision-makers. At the same time, communities may not receive clear information about decisions, approvals or delays that affect them. These gaps make it harder for water governance systems to respond with accountability. International donor funding has also helped entrench an overdependence on "verifiable indicators," like people trained, meetings held, plans approved and structures built. When programs are assessed mainly through what can be counted, they risk missing the realities that determine whether water governance actually works - the connective tissues between people and institutions that make things actually happen. The gender gap reality. In several focus group discussions, women were not described as formally excluded from village meetings. Rather, this manifested in more subtle ways as social expectations shaped whether they felt it was appropriate to attend or speak. "While women are not prohibited from attending any meeting, it doesn't seem proper for them (hume shobha nahin deta) to attend, while the men of the household are already attending," said Sarita Devi*, a frontline worker in Bundelkhand. This nuance of self-censorship matters. Many water-related decisions pass through the Gram Sabha or the village assembly, where residents discuss and approve local development priorities, including water security plans and public works. Reports may show that consultation happened and that women attended the meeting, however, they do not show who stayed silent, who was absent, or whose concerns shaped the final decision. Listening differently. Local experiences must not be dismissed as anecdotal. They often explain the practical and institutional conditions that determine whether an intervention succeeds: how decisions are negotiated, where implementation breaks down, and whether community priorities are recognised beyond the village level. The Rajasthan pilot did not replace formal meetings, field engagements or program relationships. Instead, it offered another way to collect qualitative feedback, analyse it quickly and return it for discussion with the community. *Names have been changed to protect privacy This three-part series follows a pilot study in Rajasthan, India, where researchers worked with community water volunteers to explore how lived experiences and AI-assisted feedback can strengthen the design and governance of water interventions.

Lake Chad is gaining water and that reshapes the irrigation agenda. IWMI estimates targeted irrigation investments around a recovering Lake Chad, could feed more than 12 million people and unlock billions in economic gains. For decades, Lake Chad has been portrayed as a symbol of environmental collapse: a once-vast lake that lost around 90% of its open-water area between the 1960s and the 1990s. Climate variability and growing irrigation withdrawals were widely blamed for its decline, and images of a disappearing lake became shorthand for climate crisis in the Sahel region - which links the Sahara Desert to the savannas of the South. International Water Management Institute (IWMI) research, tracking the lake by satellite every quarter from 2000 to 2025, tells a different story. Lake Chad is not disappearing. It is gaining water and has been for years. For nearly 30 million people who depend on the basin's waters for farming, fishing and daily life, these findings have deep implications. Through its work, conducted in partnership with the World Bank, IWMI found that the lake's open-water area more than doubled. Rising from about 3,600 square kilometers (km[2]) in 2012 to over 8,300 km^2 in 2025. The rebound is clearest in the lake's northern pool, which had almost vanished by 2012, and has since expanded so markedly that it now covers a greater area than the southern pool, though it remains shallow. IWMI noticed that stronger inflows from the Komadugu-Yobe river system have been returning open water to the northern basin since 2019. Just as important is how the lake behaves. IWMI also observed that, rather than uniformly shrinking or growing, Lake Chad is best understood as a shifting mosaic of open water, wetlands and vegetation that expand and contract from year to year. Much of what was once read as "disappearance" was in fact water moving between these states, a dynamic wetland system, not a dying one. So, what changed? Rain, mostly. Its analysis shows that across the entire basin, annual rainfall rose by roughly 100 mm, or about 16% between 2000 and 2020. The river basins that feed the lake gained even more, with the Komadugu-Yobe up nearly 18% and the Chari-Logone increasing by around 11%. A second, smaller factor points in the same direction. Since 2014, political insecurity in the Komadugu-Yobe basin has forced some irrigation schemes to be abandoned, cutting local water withdrawals and leaving more water in the river, that then flow into the northern basin. The lake's recent recovery may be more than a temporary fluctuation. Using five downscaled climate models from the Inter-Sectoral Impact Model Intercomparison Project (ISIMIP), IWMI assessed how temperature, rainfall and river flows could change across the basin in the coming decades. The models indicate that both temperatures and rainfall are likely to increase. Importantly, the projected rise in rainfall is expected to outweigh the additional water lost through evaporation, potentially resulting in greater river discharge into Lake Chad. The lake's recovery since 2019 is consistent with this long-term climate signals. However, considerable uncertainty remains in the projections. The models agree on direction but diverge on the magnitude and timing of change so these outlooks should be read with caution. What is Lake Chad's irrigation potential? The Lake Chad Basin is shared among six countries - Cameroon, Central African Republic, Chad, Libya, Niger and Nigeria. The people of each country depend on the basin for water, farming, fishing and other livelihoods. Yet, according to its research less than 6% of the basin's land with potential for cultivation is currently irrigated. Greater water availability could support agricultural production, strengthen food security and create new economic opportunities. But expanding irrigation without considering the needs of the wider basin could undermine the environmental flows on which Lake Chad depends. To help answer that question, IWMI carried out an integrated analysis of the basin's irrigation potential, assessing not only how much irrigation could be developed, but where it can be developed sustainably and where it cannot. The assessment examines three pathways: rehabilitating and expanding existing public schemes; Farmer-Led Irrigation Development (FLID) which is typically powered by groundwater; and combinations of the two. The analysis estimated this potential country by country. IWMI quantified that around 33 million hectares of land had potential for groundwater-fed FLID, while around six million hectares had potential to be irrigated by surface-water schemes. However, a key finding was that while tens of millions of hectares are in principle suitable for irrigation, only a fraction can be developed sustainably within available water budget limits under climate change. Realistically, with strategic investments, the six countries could potentially expand irrigated agriculture by around one million hectares. But success depends on where water resources, land conditions and local communities are best positioned to make irrigation most likely to succeed. FLID can expand quickly and inclusively, but groundwater is the catch: across all six countries, aquifer abstraction is essentially unmonitored. Regional coordination will determine what happens next. More water does not automatically lead to sustainable development. The Lake Chad Basin is shared, which means irrigation expansion in one location can affect water availability, ecosystems and livelihoods elsewhere. Countries therefore need shared information, joint monitoring and investment plans that consider this transboundary basin as a connected system. This irrigation assessment by IWMI estimates that well-targeted investment could feed more than 12 million people and generate tens of billions of dollars in economic benefits. Irrigation development must go hand in hand with flood-management measures. A wetter future is also likely to be a more flood-prone one, so new infrastructure should be designed to cope with higher flows and periodic flooding. Building on the long-standing role of the Lake Chad Basin Commission, member countries can strengthen joint monitoring, improve data sharing and, where appropriate, revisit regional water-allocation frameworks such as the Water Charter. Lake Chad's revival is real, and the science is now clear enough to plan around. The central question is no longer simply whether Lake Chad is disappearing. It is whether the countries sharing its waters can turn its recovery into lasting food security, livelihoods and resilience without placing the lake itself at risk. Editor's note: This blog draws on findings from an unpublished research study conducted by IWMI and partners
From Baku to bankable. How FCDO and IWMI are turning pilots into investment opportunities with international financial institutions in fragile contexts. As the global funding landscape shifts and pilot projects mature, a new challenge emerges: how do successful resilience interventions move from small-scale testing to nationally financed programs? For the United Kingdom's Foreign, Commonwealth & Development Office (FCDO) and the International Water Management Institute (IWMI), the Islamic Development Bank Group (IsDB) Annual Meetings and Resilience Dialogues in Baku, Azerbaijan provided an opportunity to test a shared answer to this question. IWMI has led several projects funded by UK International Development that are reaching maturity and looking for pathways to scale. Al Murunah pilots resilient nature-based water solutions (RNBWS) for water and food security in agricultural communities of Egypt, Jordan, Lebanon and Palestine. Al Murunah+, supports Al Murunah by delivering household- and community-level resilience-building to promote positive gender norms and support the uptake and sustainability of climate adaptation interventions. Jahez builds climate-ready refugee-hosting communities in Jordan through scalable impact-based weather and climate information systems, community-based anticipatory action and RNBWS for disaster risk reduction. Wiqaya pilots RNBWS to mitigate sand and dust storm generation and improve livelihoods equitably in southern Iraq and scale mitigation efforts through capability building, planning and dialogue to leverage national and regional climate finance. As these pilots near completion, and with clear proof of concept established, International Water Management Institute is exploring how to scale the partnerships and evidence-based approaches to cement a legacy that continues to build resilience in fragile contexts. This was the reason IWMI and the FCDO travelled to Baku together, as one delegation, with IWMI serving as the technical and knowledge arm of the FCDO team. Why the Resilience Dialogues matter. As part of their Annual Meetings, IsDB hosted a two-day Resilience Dialogue, which stood out as an excellent opportunity for International Water Management Institute. Ministers, multilateral development banks (MDBs), UN agencies and development partners participated in a South-led discussion on what is required to improve crisis response and support investable resilience programming. Across roundtables on the Sahel, Syria and Horn of Africa, and the launch of IsDB's new "3R Facility" - response, recovery and resilience - two messages rang out clearly: capital is increasingly available, but there remains a shortage of bankable, conflict-sensitive and technically sound projects; and investments in water systems can provide a critical entry point for climate resilience, food security and economic recovery, yet many lack the evidence base and design needed to attract large-scale financing. This gap is exactly where IWMI's projects sit. From evidence to a legacy that scales. Together, IWMI and the FCDO aim to distil outputs and learnings from these projects into synthesized and investment-ready intervention bundles and implementation models that governments, development banks and financiers can adopt, adapt and scale in other fragile and conflict-affected settings. This provides MDBs and climate financiers robust evidence and an implementation blueprint, enabling proven water-centred resilience investments to begin from an advanced starting point. A joint offer, built for new platforms and pipelines. In roundtables and bilateral meetings at Baku, International Water Management Institute tested a shared proposition: whether FCDO's international climate finance, policy, and partnership and convening power, paired with IWMI's research for development and conflict-sensitive design, could create opportunities for development finance institutions to turn resilience priorities into investment-ready pipelines. This offer arrives at the right moment for recent and emerging South-led platforms such as the Baku Hub, IsDB's 3R facility and the Riyadh Global Drought Resilience Partnership. Each requires the kind of investment-ready and rigorously prepared projects that learnings and approaches from projects like ours can inform. Aligning with national and regional ambitions. This work ties together national development and climate adaptation plans, the UK's International Climate Finance Strategy and IWMI's Country and Regional Strategic Roadmaps. Water is a foundational platform globally for food security, jobs and peace. This is the case across Chad and the Sahel, for Syria's early recovery, in Sudan's reconstruction, for Yemen's dam-linked livelihoods and for disaster preparedness in the Horn of Africa. Its engagement in Baku reinforced how IWMI's projects align with these national visions, and how they can be adapted and scaled through local leadership and regional institutions. Looking ahead, together. Baku confirmed something International Water Management Institute already believed: FCDO and IWMI are stronger working together. As its UK International Development funded pilots mature, its shared task is to make sure their evidence and models inform the next investments for high-impact development. It marks a shift in the FCDO-IWMI collaboration: from successful implementation, through strategic reflection, to a future where water security drives inclusive, resilient development at scale. International Water Management Institute leave Baku with a clear path forward and a renewed conviction that when diplomacy, financing, policy, and applied research for development move together and are anchored in local realities, evidence, and knowledge, International Water Management Institute respond to crises and build resilient systems with communities that endure. The UK's International Climate Finance Strategy includes two relevant priorities: mobilizing finance at scale for climate and nature outcomes and accelerating a transition to climate-resilient communities, economies and ecosystems. To deliver on these priorities, its next chapter is not just about sharing lessons; it is to ensure that evidence generated in these projects shapes the next generation of climate resilience investments. Baku demonstrated that demand exists. The task is now to translate evidence into pipelines, pipelines into finance and finance into resilient systems that can better withstand future shocks. International Water Management Institute is excited for what comes next. IWMI and the FCDO will continue turning knowledge into action - driving bankable, impactful investments.

IWMI launches ENSO Outlook to turn El Niño forecasts into anticipatory action. The reliability of modern climate predictions presents a window of opportunity in which to act to prevent the worst impacts from the phenomenon. July 22, 2026 | By IWMI On June 18, the International Water Management Institute (IWMI) launched the ENSO Outlook tool at the 2026 El Niño Webinar, to support nations prepare for the coming El Niño challenges. Capable of sophisticated analysis, the ENSO Outlook brings together data on a host of El Niño climate signals - from rainfall and soil moisture to vegetation health - and uses artificial intelligence to predict what those signals will mean for water resources, agriculture, food systems and livelihoods. It presents data on scales from global to national, enabling governments to take targeted preparatory actions to unlock farming services, insurance, finance and more. With scientists forecasting that El Niño will threaten crops and livestock through severe droughts and erratic rainfall from now until early 2027, concerns over food security are growing. East and Southern Africa are likely to be hardest hit as they face below-average rains, flooding and extreme heat across different areas that could intersect with existing vulnerabilities - such as conflict, high fuel and fertilizer prices, and weak recovery from prior weather shocks. Also likely to be affected are Latin America and the Caribbean, and South and Southeast Asia. While this is gravely worrying, the reliability of modern climate predictions presents a window of opportunity in which to act to prevent the worst impacts from the phenomenon - which is the warm phase of the naturally occurring El Niño-Southern Oscillation (ENSO) climate pattern. El Niño's well-established influence on rainfall can be used to understand likely impacts on crop yields, livestock, fisheries and food security. When combined with data on communities' existing vulnerabilities this can help form the basis for effective anticipatory action. Water availability underpins food security, so using short- and medium-range forecasts to prepare at multiple levels, for disruption to water supplies is vital. For farmers, this could look like making a timely switch from growing water-intensive rice to less thirsty maize or millet, and could be the difference between crop failure or survival during a period of extreme drought. Being informed of such events in advance can ensure ministries are prepared for compound impacts that ripple across crop production, food prices, market volatility, health and more. 'El Niño is not just a climate issue, it's a global risk multiplier that can influence rainfall, drought, flood, heat stress, crop production, water availability, food security and livelihoods in vulnerable regions,' warns Giriraj Amarnath, research group leader on Water Data for Climate Resilience and principal researcher on Disaster Risk Management and Climate Resilience at IWMI. While cereals are often the focus of food security, the potential impacts of El Niño on livestock, fisheries and aquaculture must not be overlooked. Depleted animal and aquatic foods often result in the first cuts in nutrition and income for poor families but such losses tend to be undercounted in response planning. For example, small-scale fisheries generate roughly 40% of the world's wild-caught fish and supply nutrients to over 2.3 billion people. One protective tool in this regard is satellite-based livestock and fisheries insurance, where earth-observation data is used to help verify claims. However, this requires parallel social protection schemes to ensure households remain able to pay the premiums. Applying a 'One Health' approach - which aims to balance and optimize the health of people, animals and ecosystems - is also valuable. With extreme weather potentially affecting animals' immunity, this might involve monitoring livestock for disease and establishing vaccination programs where required. Many countries expected to be hit hard by the evolving El Niño are highly fragile and are often crisis hotspots. For such locations, it is not enough to simply forecast climate risks, as understanding is needed of how weather shocks interact with existing conflict, weak institutions and food insecurity. Such challenging contexts call for triangulating climate and non-climate datasets to pinpoint hotspots for action; tailoring science to respond to policymakers' needs; and investing in partnerships to build trust at the local level. As the world grapples with an evolving El Niño, understanding the potential impacts and taking anticipatory action is critical. IWMI's ENSO Outlook helps countries translate climate forecasts into early action, supporting practical decisions for food, land and water systems, protecting both food security and livelihoods.
Early farmer impressions from the Water & Soil Accelerator program in Central Malawi. WASA is helping Central Malawi's farmers turn soil and water challenges into practical climate resilience through science, demonstration plots and farmer-led choices for lasting harvests. July 16, 2026 For many smallholder farmers in Central Malawi, the challenge is no longer only about producing more but about producing under increasingly difficult conditions. From unpredictable rainy seasons, declining soil fertility, rising input costs, and dry spells that can reduce crop performance even when farmers have done everything right. In this context, the Water & Soil Accelerator (WASA) Program is offering a glimpse into why soil and water management must be treated as a core part of climate resilience. Implemented by the International Water Management Institute (IWMI) in partnership with CIMMYT, and other partners, WASA aims to accelerate the adoption of climate-smart soil and water management practices among smallholder farmers in Zambia and Malawi. In Central Malawi, the program's mega demonstrations are testing and showcasing practical options for Conservation Agriculture (CA), focusing on minimum soil disturbance, crop residue retention, crop diversification, and maize varietal assessment. The work builds on CIMMYT's more than two decades of research and promotion of CA across Southern Africa. Over the years, CIMMYT and partners have generated evidence that practices such as reduced tillage, residue retention, crop rotations, intercropping, and improved varieties can contribute to better soil structure, increased water infiltration, reduced erosion, and more stable yields under variable rainfall. This experience provides an important scientific foundation for WASA as it enters a new phase of implementation, adaptation, and farmer learning. CIMMYT's role in the consortium includes developing field implementation protocols, coordinating agronomic research, strengthening partner capacity, and supporting the generation of field-based evidence. In the first year, this has been particularly important as the credibility of the demonstrations depends on the quality of site selection, plot demarcation, trial layout, crop management, and data collection. The Training of Trainers adopted a participatory co-learning approach, combining technical sessions, field demonstrations, and hands-on practice. Field teams worked through nine treatment configurations, including maize varietal comparisons, maize-groundnut and maize-cowpea intercrops, maize-legume rotations, and double- and four-row strip cropping systems. For many participants, strip cropping was a new concept, requiring careful discussion on spatial arrangement, fertilizer placement, crop interactions, and the type of data to be collected, including yield, biomass, residue cover, and labour use. "For these technologies to be useful beyond the demonstration plot, the people implementing them must understand the science and the field reality," said Dr Blessing Mhlanga, CIMMYT Cropping Systems Agronomist (Associate Scientist). "The co-learning approach allows researchers, field staff, and farmers to engage practically with the treatments, ask questions, and build confidence in practices that can be adapted to local conditions." Early observations from Central Malawi show encouraging levels of farmer interest and acceptance, while also revealing the practical issues that will shape scaling. In Chipeni, located in Dowa district, farmer Loveness Mwale's site showed strong establishment across all plots, with visible varietal differences. Farmers were able to compare crop performance under the same conditions, and two farmers selected rotations and two-row strip cropping as options they were interested in taking forward. This suggests that farmers are not simply receiving information, but they are assessing options and making choices based on what they experience. At Loice Maliwa's site, the trial was well laid out, with good weed management, strong crop establishment, and consistent spacing. Farmers demonstrated an understanding of the concepts being tested, showing that the training approach is helping translate research protocols into practical field management. In Chinguluwe, where a cooperative of 51 farmers is participating, the demonstrations have created an important space for collective learning. Although signs of dry spell stress were visible in maize, the overall crop stand was good, and cowpea had many pods. Farmers also raised important market considerations. While cowpea performed well in the field, many preferred groundnuts because they fetch higher prices and have more reliable markets. This feedback is critical because adoption depends not only on agronomic performance, but also on income potential, labour demand, market access, and farmer familiarity. For Christian Thierfelder, CIMMYT principal cropping systems agronomist, WASA reflects the kind of integrated science and partnership needed to respond to climate pressure in smallholder farming systems. "This program connects long-term CA research with practical implementation at scale," he said. "It brings together science, innovation, and partnerships in a way that supports CIMMYT's broader strategy of building more productive, inclusive, and resilient agrifood systems." In its first year, WASA is already showing value as a research and learning platform. The mega demonstrations are helping farmers assess drought-tolerant varieties, rotations, intercropping, strip cropping, and soil and water management practices under real field conditions. The results are promising, but the program is also generating something equally important: farmer feedback that can guide iterative refinement and scaling. As implementation continues, WASA's strength lies in combining scientific evidence with farmer decision-making. For smallholder farmers in Central Malawi, this means having access to tested options that can improve water use, rebuild soil health, and support more stable production in a changing climate.
