Climate change has been accelerated with clear evidences in Vietnam. According to climate change scenarios, the annual mean temperature in Vietnam would increase by 1.1--3.6oC in 2100 while the sea level would rise by 65-100 cm, and extreme weather events would happen more frequently (MONRE, 2009). Climate change will probably result in flooding, declines in cultivated areas, and decrease crop yields, thus placing a great challenge for food security in Vietnam. Several adaptation measures for crop production, such as the changes in crop structure and crop calendar, the introduction of new varieties and farming techniques, and improved irrigation systems have been applied, and the initial successes have been recorded. To respond more actively to climate change and mitigate its induced negative impacts on crop production, it is very necessary to enhance the adapting capacity and implement more adaptation measures in the coming time.
