The effect of temperature rise to rice crop yield in Indonesia uses Shierary Rice model with geographical information system (GIS) feature

摘要

The temperature rise is one of issues of climate change that has the effect of rice production in Indonesia, especially to the development and growing of plants. This research used the Model of Shierary Rice with Geographical Information System (GIS) to estimate the decreasing of rice production in every province in Indonesia based on some scenarios of temperature rise. The model used the Shierary Rice to estimate the rice production and Shierary Weather to forecast the weather on the certain location based on the condition of normal climate. The result of research showed that temperature rise would make the age of rice the shorter and decrease the rice yields. This research pointed out that irrigated farm having less impact from temperature rise compared with rainfed farm which had the decreasing of rice yield for 11.1%/OC and 14.4%/OC sequentially as well.
