Initial results of rice productivity projection under impacts of climate change in Nam Song Ma irrigation system

Abstract

       Vietnam is one of five countries in the world most influenced by climate change. Climate change affects many human activities including agricultural activities and food production. Therefore, plant productivity projection under climate change condition is very important in the future (especially for rice). The article will provide initial investigation results of rice productivity under general impact of temperature increases, precipitation and CO₂ concentration changes in the future in Nam Song Ma irrigation system, Yen Dinh, Thanh Hoa. Results shows that rice productivity in summer-autumn and autumn-winter crops are increased by 34% and 20%, respectively, until 2099 in A2 scenario. While those figures in B2 scenario are 19% and 14%.
