Rice is perhaps the most important crop in Vietnam’s agricultural sector. About 52% of paddy rice production is from the Mekong River Delta: 82% of the summer autumn rice is produced in the Mekong River Delta, and another 18% in the Red River Delta. Other important rice-growing regions are the North-East and the North-Central Coast. In most zones, irrigated rice is cultivated in two to three crops per year. The continued rise in rice production is largely due to improved irrigation, new rice varieties, new rice technologies, and increased triple cropping in the Mekong River Delta. Development has involved increasing control over natural hydrological processes and has involved water and land management trade-offs which have at times disadvantaged poorer groups. Climate change threatens multiple stressors on rice production, including high temperatures (particularly during development stages), saline intrusion, drought, and flood (crop submergence).
This section provides insights into the climate change impacts on agricultural productivity indicators and the trends in agriculture related socio-economic indicators.
