    Water scarcity threatens East Africa’s rice production, and adopting climate-smart irrigation is crucial to boost yields, resilience, and regional food security.
    – Bwire et al. 2025

    Rice is rapidly emerging as a staple crop in East Africa, particularly in Uganda, Kenya, Tanzania, and Ethiopia. Despite its growing importance, more than 90% of rice is produced by smallholder farmers using traditional rain-fed or flooded methods, leaving production highly vulnerable to water scarcity. Climate change, poor irrigation infrastructure, and erratic rainfall have made water availability a major constraint, threatening yields and exacerbating food insecurity. The region’s reliance on imports underscores the production gap—East Africa brings in over 500,000 tons of rice annually, primarily from Asia, despite having significant agricultural potential. This dependency persists due to limited technical knowledge among farmers, inadequate funding and infrastructure, weak policy support, poor institutional coordination, and gender disparities in access to resources.

    The study identifies three climate-smart irrigation practices with potential to transform rice production:

    • Alternate Wetting and Drying (AWD): Cuts water use and methane emissions in paddy fields.
    • System of Rice Intensification (SRI): Boosts yields while reducing water and input requirements.
    • Drip Irrigation: Highly efficient for upland rice but hindered by high costs and low awareness.

    These challenges intersect with broader regional issues. Over 70 million people in East Africa are undernourished, and agriculture faces mounting climate risks, including droughts, rising temperatures, and unpredictable rainfall. Civil unrest, migration, and climate-induced displacement further strain food systems. Effective water management, combined with investment in irrigation, farmer training, and supportive policies, is critical to strengthening rice production and ensuring long-term food security in the region.

    How the Study was Conducted

    The study was a comprehensive literature review and synthesis of existing research, reports, and data on water management and rice production in East Africa, focusing on four key rice-producing countries—Uganda, Kenya, Tanzania, and Ethiopia. Drawing on peer-reviewed scientific literature, government and NGO reports, agricultural statistics from FAO and other databases, as well as case studies and field-level experimental trials, the authors examined a wide range of interlinked issues.

    The review explored the impacts of climate change on water availability and rice farming, the adoption and performance of climate-smart irrigation technologies such as alternate wetting and drying (AWD), the System of Rice Intensification (SRI), and drip irrigation, as well as the socioeconomic and institutional barriers that hinder technology uptake. It also assessed food security trends, historical and ongoing irrigation development efforts, and the effectiveness of various water management strategies.

    A comparative analysis was conducted to evaluate rice production trends, irrigation practices, and food insecurity across the four countries. The authors reviewed results from experimental and pilot projects involving AWD, SRI, and drip irrigation, integrated regional climate models and drought indicators to assess vulnerability, and examined relevant national policies, land tenure systems, and institutional frameworks. The socioeconomic context—covering gender roles, migration patterns, poverty, and civil unrest—was also considered as a critical factor shaping food security outcomes.

    However, the study faced limitations, as much of the available data came from small-scale trials or single-site studies, restricting the generalizability of findings. Additional challenges included gaps in up-to-date irrigation and yield statistics and a lack of high-resolution climate and agricultural data for the region.

    What the Authors Found

    The study found that water scarcity—worsened by climate change—is the biggest constraint on rice production in East Africa, and while climate-smart irrigation technologies could greatly improve yields and water efficiency, their adoption remains extremely low due to cost, limited awareness, and weak institutional support. Without urgent improvements in water management, farmer training, and governance, food insecurity will persist despite growing rice demand and production potential.

    Why is this important

    Food Security at Stake – Over 70 million people in East Africa are undernourished, and rice is emerging as a staple; boosting local production is essential for nutrition and livelihoods.

    High Climate Vulnerability – Frequent droughts, erratic rainfall, and rising temperatures are undermining traditional farming, making climate-smart water management critical.

    Water Management as a Game-Changer – Rice is highly water-intensive; technologies like AWD, SRI, and drip irrigation can significantly improve yields, yet poor infrastructure and governance hinder progress despite abundant water resources.

    Economic and Social Benefits – Increasing domestic rice production can cut annual imports of over 500,000 tons, save foreign exchange, empower smallholder farmers, and address gender inequalities in agriculture.

    Urgent Need for Action – Without timely interventions in technology adoption, farmer training, and policy reform, climate change will worsen food insecurity, drive migration, and heighten conflict risks.

    What the Authors Recommended

    • Provide training, on-site demonstrations, and farmer field schools to promote climate-smart irrigation (AWD, SRI, drip), while ensuring women have equal access to resources and decision-making.
    • Rehabilitate and expand irrigation schemes, promote affordable smallholder-friendly tools like solar pumps and drip kits, and develop systems for rainwater harvesting and storage.
    • Create integrated ICT platforms for real-time farming advice, establish early warning systems for drought, and expand long-term research on water-saving technologies and their environmental impacts.
    • Strengthen water governance, improve inter-ministerial coordination, secure land rights, and align policies across agriculture, water, and the environment to support sustainable rice production.
    • Facilitate cross-country knowledge exchange and build public–private partnerships to scale proven water management solutions across East Africa.

    In conclusion, adopting climate-smart water management in East Africa’s rice sector offers a transformative path to boost yields, reduce imports, and strengthen food security, but urgent investment, policy reform, and inclusive farmer support are essential to realize this potential.

    Water: The Cornerstone of Sustainable Development and Human Prosperity

    Water is the bedrock of life and a cornerstone for building a liveable planet. It is fundamental to human survival, agricultural productivity, economic advancement, and ecosystem stability. Yet, this invaluable resource is facing escalating threats from climate change, population growth, and poor management. The world is at a critical juncture: if we are to eradicate poverty and ensure a sustainable future, we must radically transform the way we manage, use, and value water.

    Recognizing this urgency, the World Bank has launched a comprehensive new global water strategy. This ambitious roadmap aims to secure water for people, for food, and for the planet—aligning with broader global development goals and climate adaptation efforts.

    Water Investment as a Driver of Economic Growth

    Water is far more than a natural resource—it is a vital economic input. It supports job creation, industrial output, public health, and gender equity. In regions where water access is stable and sustainable, productivity in agriculture, energy, and manufacturing flourishes. Conversely, water scarcity can devastate livelihoods, as demonstrated by Cape Town’s 2018 drought, which led to the loss of 20,000 agricultural jobs.

    Conversely, investments in water security create transformative opportunities. For instance, in the Democratic Republic of Congo, an expansive water access program is projected to generate approximately 30,000 jobs. Similarly, access to clean water and sanitation services alleviates public health burdens and enables women—who often bear the brunt of water collection responsibilities—to pursue education and employment.

    Ultimately, investing in water is investing in people. It’s about building resilient, inclusive economies that thrive under the pressures of climate variability and global economic shifts.

    Bridging the Financing Gap

    Securing universal access to safe water and sanitation is not just a policy challenge—it’s a financial one. Achieving the Sustainable Development Goals for water requires an estimated annual investment of $131–$140 billion, nearly double current levels. This financing challenge cannot be met by public resources alone. A bold, coordinated approach involving both the public and private sectors is essential.

    The World Bank’s flagship report, Funding a Water-Secure Future, underscores several systemic inefficiencies: low budget utilization, misallocated subsidies, and weak institutional capacity. Strengthening public institutions, introducing performance-based utility reforms, and deploying smart subsidies that benefit the poor can vastly improve sector performance and attract greater volumes of private and international capital.

    Unlocking the Power of Private Sector Innovation

    Private enterprises play an indispensable role in reimagining how we finance and deliver water services. Their ability to innovate—through advanced technologies, performance-based contracts, and blended finance models—offers promising solutions to longstanding water challenges.

    The World Bank is actively enabling this participation by improving regulatory environments, offering de-risking mechanisms, and fostering transparent governance. These initiatives not only reduce investor risk but also build the foundation for impactful, large-scale private sector engagement.

    Harnessing Innovation for Resilient Water Systems

    Technological innovation holds immense potential to revolutionize the water sector—but adoption has lagged, particularly in low- and middle-income countries. Only a fraction of water utilities currently utilize cutting-edge tools like artificial intelligence, predictive analytics, or digital twin modelling.

    Modern sensor technologies and data platforms could transform water quality monitoring, optimize distribution networks, and reduce waste. To accelerate progress, national policies must foster an innovation ecosystem—one that promotes research, scales viable solutions, and equips water professionals with the skills needed to adapt.

    By embedding innovation at the heart of water management, we can create smarter, more efficient, and climate-resilient water systems.

    A Global Strategy for Water Security

    The World Bank’s updated water strategy integrates its technical expertise, partnerships, and financial instruments to deliver water for three interconnected objectives:

    1. Water for People: Achieving universal access to water, sanitation, and hygiene (WASH) services.

    2. Water for Food: Enhancing water efficiency in agriculture to secure food systems and smallholder livelihoods.

    3. Water for Planet: Managing water resources sustainably to reduce risks and preserve ecosystems.

    Through its new Fast Track Water Security and Climate Adaptation program, the World Bank is scaling up and accelerating water solutions. This program fosters rapid innovation deployment and cross-sectoral partnerships—bridging public and private actors to confront water crises at scale.

    In Africa’s Sahel region, where 99% of farmland is rainfed, the Sahel Irrigation Initiative is transforming agriculture. Using modern irrigation tools like drip systems and solar pumps, the project is improving the livelihoods of nearly 400,000 farmers. Stories like that of Fattah Hassan Dubaal in Chad—whose okra yields increased fiftyfold—demonstrate the power of reliable water access to uplift entire communities.

    Ethiopia: Menstrual Health, Sanitation, and Education

    The One WaSH National Program in Ethiopia has built 227 menstrual hygiene rooms in over 1,000 schools. These gender-sensitive facilities have significantly improved school attendance among girls. Addressing menstrual stigma and integrating hygiene education into school curricula are critical to inclusive education.

    Egypt: Expanding Rural Sanitation

    In Egypt, the Sustainable Rural Sanitation Services Program has already improved access for over 1 million people. By investing in treatment infrastructure and connecting more households to the sewer network, the project strengthens governance and service delivery in the sanitation sector. It also laid the groundwork for Egypt’s National Water and Sanitation Strategy.

    Toward a Water-Secure Future

    Water flows through every facet of human development. Ensuring its availability, quality, and sustainable use is not merely a technical challenge—it is a moral imperative and economic necessity. The World Bank, as the largest multilateral financier of water in developing countries, is mobilizing its $27 billion portfolio to catalyze change at scale.

    Through bold investments, institutional reform, and innovation, the new global water strategy seeks to deliver water solutions that empower people, nourish economies, and preserve the planet. Only through such integrated and accelerated efforts can we secure a future where water continues to sustain life, dignity, and development for all.
