Abstract

Flood is one of the disasters that often occur in Indonesia. Based on data published by National Disaster Management Authority of Indonesia, floods tend to increase. Currently, flood is triggered by global climate change and land use/land cover change. Based on the impact of disasters on agriculture and food security, flood is one of the disasters that have the greatest impact on the loss of agricultural production, specifically rice. Flood will have an impact on the pillars of food security assessment, especially on the availability, which will decrease the amount of rice production yield. This study attempts to assess the potential loss of rice production due to flood in the northern coast of West Java Province. In this area, there are several regencies that produce the highest rice production and are national granary, such as Indramayu, Karawang, and Subang. The northern area of West Java Province also has the potential for flooding with a significant area, although the height of the inundation does not as high as the area in the central part of West Java Province. The assessment of the potential loss of rice production was carried out using a vulnerability curve that shows the relationship between the height of flood inundation and the loss percentage of rice production.
