Evaluation of climate change impacts and adaptation measures for rice cultivation in Northeast Thailand
by Mukand S. Babel, Anshul Agarwal, Dillip Kumar Swain, Srikantha Herath
- Study investigates the impact of climate change on rainfed rice yield in Northeast Thailand.
- Utilizes CERES-rice crop growth model to assess effects and identify agro-adaptation measures.
- Calibrates the model using field experiment data from the region.
- Develops future climate scenarios for three periods using ECHAM4 and PRECIS.
- Projected yield reductions under ECHAM4 A2 scenario: 17.81% (2020s), 27.59% (2050s), 24.34% (2080s) compared to 1997-2006 average.
- Rice varieties KDML105 and RD6 show increased yields with higher CO2 concentrations, but elevated temperatures reduce yields.
- Nutrient management and adjusted planting dates can mitigate yield decrease under future climate.
- Hybrid rice cultivars with high temperature tolerance can help address climate change challenges.
