Abstract
Climate change has a negative impact on rice production in Indonesia. This research was conducted to identify problems caused by climate change on agriculture, identify the technology to address climate change, and analyze the technological adaptation to encounter the climate change problems in West Java. Problems arising from climate change include increasing air temperature, rainy season shift, and prolonged drought. The impact of climate change on agricultural land in West Java is prolonged drought and land degradation. The most appropriate technology to be applied in West Java in order to address climate change is System of Rice Intensification (SRI). SRI rice cultivation can save water up to 30% compared to conventional cultivation, so it can be applied when the water resources was limited. SRI method that has been applied in West Java shows that organic rice farming produces more rice than inorganic farming. The productivity of inorganic farming are 6.0 - 7.0 tons / ha, whereas the SRI organic farming could produce 8 - 9.2 tons / ha grain. The application of the SRI method in Cibarengkok Village, Bojong Picung, West Java produces 7-8 tons / ha of grain, while the conventional method yields 4-5 tons / ha of grain.
Highlights
Climate change is a global problem in recent decades and has become a major issue in various forums of discussion both nationally and internationally
September already entered the rainy season, but this time the rainy season begins in October, so it affects the process of rice cultivation in West Java
The results show that organic rice farming produces more than rice harvest inorganically
Summary
Climate change is a global problem in recent decades and has become a major issue in various forums of discussion both nationally and internationally. Climate change is a phenomenon that results in erratic weather and the resulting disruption to the survival of living beings. The impact of climate change can be observed in various sectors such as forest fires that severely damaged by El Nino, the difficulty of obtaining clean water in some areas due to the prolonged drought, the rising sea levels, the emergence of new diseases that threaten human health [1]. Climate change affects agriculture and food sector. The agricultural sector is vulnerable to climate change as it affects cropping patterns, time of planting, planting index, productivity, and quality of results. Based on Suberjo [2], climate change through global warming would reduce agricultural production by 5-20%
