Assessing the vulnerability of food farming system to support climate change adaptation: A case study in Java, Indonesia

Abstract

Increasing resilience to climate change is one of the priorities of the Government of Indonesia. Climate change has a significant impact on the agricultural sector and is projected to global gross domestic product. Java Island, as a center of food production, has a strategic location because of its strong impact on food availability in Indonesia. The study aimed to provide information about the status of the vulnerability of farming system for food at the district/city level in Java Island and the determinant factors that affect the level of vulnerability. The analysis was based on soil fertility, water availability and demand, climate, and socio-economy expressed in terms of exposure and sensitivity index and adaptation capacity index using the quadrant method. The results show that 20% of districts/cities in Java have very high levels of vulnerability. The main determinants identified in Java are the ratio of the number of extension agents and the number of farmer groups/rice field area and the rice consumption ratio to total carbohydrate food. The results of this study can be used as a reference in determining priority locations and formulating adaptation programs and actions to reduce the impact of climate change.
