A recent study by Bwire et al. (2025) titled “Water management for rice production: a key component of food security in East Africa” published in Discover Water reveals that more than 90% of rice is produced by smallholder farmers using traditional rain-fed or flooded methods, leaving production highly vulnerable to water scarcity.

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.
