Closing Rice Yield Gaps in Asia with Reduced Environmental Footprint or CORIGAP aims to improve food security and gender equity, and alleviate poverty through optimizing productivity and sustainability of irrigated rice production systems in China, Myanmar, Thailand, Vietnam, Indonesia, and Sri Lanka.

Through best management practices, CORIGAP improved livelihoods for 0.5 million farm households.

Efficient use of water, pesticides, and nutrient efficiency led to better natural resource management and improved ecosystem services by 10% for 0.2 million people
