Salinization, as aggravated by climate hazards, has been significantly affecting rice production in the Mekong River Delta, a major rice production region in Vietnam. What can farmers do to effectively respond to salinization and ensure farm production is maximized? Suggested solutions-massive promotion of Good Agricultural Practices (GAP) including cultivating saline-tolerant rice varieties among farmers up to a level that achieved significant and wider strategic adoption. To ensure institutional flexibility to respond to climate change-induced salinity and other hazards, the following policy interventions are suggested: Sustained promotion and support for research and development towards the development and wider adoption of integrated rice farming technologies that ensure high productivity and resilience; More research on effectively identifying and designing innovative ways to improve rice production efficiency along with establishing credit and insurance systems for rice farmers; Awareness building on the adverse impacts of unsustainable practices such as extensive groundwater pumping and agro-chemical application; Investments to improve varieties that have tolerance to flooding, drought, heat, and salinity and a breeding program for new varieties, while maintaining support to traditional rice varieties; Enhanced application of modern technology and science-based recommendations along with capacity development for improved rice seed quality, innovative cropping system, pest and disease management, infrastructure and enterprise development to ensure efficiency at lowest risk for farmers; Farmers' adoption of GAP, particularly the use of climate change-ready rice varieties to effectively respond to salinization and ensure farm production is maximized.
