As global water demand rises, efficient irrigation is crucial for sustainable agriculture, especially for water-intensive crops like rice. The project “Promoting productive water use and efficient water management in paddy fields,” funded by the Government of Japan and implemented by the FAO, aims to enhance productivity in Sri Lanka and Zambia by improving water use efficiency. Through pilot sites, the initiative showcases effective water management practices, strengthens stakeholder capacities, and promotes value-added paddy fields. The project seeks to bolster crop yields, food security and economic stability in rural areas, ultimately serving as a benchmark for effective water management and influencing policy decisions.
