Rice feeds over half of the world’s population and sustains 144 million people—80 percent of them smallholder farmers. With a projected 30 percent surge in demand by 2050, the rice industry will only grow in importance. But the crop’s vulnerability to climate change and slowing productivity gains, its environmental footprint, and its limited nutritional value make it clear that business as usual is no longer an option.
Many rice-producing countries are already taking this challenge seriously—introducing reforms, innovations, and investments to bring the sector into a new era of higher returns, lower emissions, and better nutrition.
Viet Nam: growing more with less
In Viet Nam, a top rice producer and exporter, half the crop comes from the fertile Mekong Delta—known as the nation’s “Rice Bowl.” Today, however, environmental degradation and the impacts of climate change are beginning to affect yields. Moreover, rice fields in the Mekong Delta region emit almost half of the country’s agriculture greenhouse gas emissions.
In response, the Vietnamese government launched the “One Million Hectares of High-Quality Rice” program to cut input costs, ease the burden on farmers, and protect soil health. However, with rice farming deeply rooted in tradition, one of the biggest challenges has been to convince farmers to adopt new practices.
“It took a lot of time to move from traditional rice cultivation to low-remission rice cultivation,” said Le Trung Thu, a member of the Cong Tien Cooperative. “But the trainings I attended helped me to be more efficient.”
Between 2016 and 2022, with support from the World Bank, Viet Nam trained over 155,000 rice farming households to grow rice using climate-resilient methods across 180,000 hectares of land. These new techniques – such as alternate wetting and drying - intermittently draining fields instead of keeping them continuously flooded - have helped farmers save money from reduced supplies and increased their profits by 30 to 35 percent.
“I have reduced production costs for seed, fertilizer, pesticide and water,” says Le Dong Phuong, a rice farmer in Can Tho City in the Mekong Delta. While Viet Nam’s average rice yield is close to six tons per hectare, Phuong is producing eight. “I can now provide for my children and cover my expenses more comfortably,” she says.
