Abstract | Water is the essential for the human beings to survive all over world. 70% of the world is covered with water, among them 1% is fresh water and 12% is ground water. Nowadays, water scarcity is increased because of global warming. Moreover, the level of surface water is reducing due to the climate change, for example, increasing temperature and decreasing rainfall, etc. This study investigates the climate change impact on streamflow and irrigation water requirement for rice cultivation in the Chindwin River Basin, Myanmar. In Myanmar, there have four major river such as Ayeyarwady, Thanlwin, Chindwin, and Sistaung. Chindwin river is multipurposed river. In this study, future climate data was obtained from three regional climate models (ACCESS, CCSM4 and CNRM), RCP 4.5 and 8.5 scenarios were used, and linear scaling was done to correct the biases. To assess the future climate was used baseline 30 years and 30years future, near future. In addition, WEAP (water evaluation and planning model) and CROPWAT 8.0 model are used to compute the water allocation and irrigation water requirement of that study. The CROPWAT model is used to calculate the irrigation water requirement and crop water requirement for rice cultivation in the baseline year (2004 – 2009) and for the future from 2010 to 2039, so called near future. The WEAP model was used to for model calibration and validation using the streamfow, and to simulate the streamflow. According to the result, future climate (near future) of the Chindwin River Basin is expected the temperature is increasing and rainfall also increased. The irrigation water requirement (IWR) was considered for two types of rice: summer rice (Jan-May) and monsoon rice (Jun- Oct). The irrigation water requirement of summer rice is expected to increase and for monsoon rice will be decreased. The result of the WEAP model shows the supply water in near future will be covered the water requirement for irrigation demand and domestic demand. The summary of these results are expected to be supportive for the irrigation planning for the rice cultivation in this study area |
