Abstract
Rainfed rice are highly dependent on rainfall resulting limitation on planting period. Meanwhile, the rainfall itself is greatly influenced by climate change. Furthermore, plant growth and quality depend on the interaction between environmental factors and plant genetic factors. This study aims to determine the impact of climate change (rainfall) on rainfed rice productivity in Merauke Regency. The research was conducted in the rainfed area of Merauke Regency as focused production center of rice. The data used in this study were data on rainfall, temperature, solar radiation, humidity, planting area, harvest area and yield. The research method used in this research is descriptive method (descriptive analysis) quantitative and qualitative analyzed by regression correlation. The climate change in 2015 gave a negative effect on rainfed lowland rice production in Merauke Regency due to decreasing of the harvest area that affected on decreasing in rice production.
