Abstract

Climate change threatens the sustainability of the agricultural sector and has the potential to affect food availability in West Java, Indonesia’s rice production centre. This study aims to examine how agricultural infrastructure has developed over the past five years and how this has affected the vulnerability index. Climate, production, agricultural infrastructure and facilities data were collected from various sources, including the Central Statistics Agency, the Ministry of Agriculture, and the Directorate General of Agricultural Infrastructure and Facilities. The data were analysed to obtain Pearson correlation values and vulnerability levels based on the ratio of production inputs to harvested area. The results show that climatic elements affect rice production in West Java, especially rainfall (r = 0.82), which is negatively correlated with production. The increase in rainfall causes significant flooding, which leads to crop failure. Production inputs such as agricultural machinery, ponds and rehabilitated tertiary irrigation networks (RTIN) support production and mitigate climate impacts. Rice production has a high Pearson correlation with the vulnerability index (r =0.75). The vulnerability ratio for West Java in 2022 was 0.0015, which means it is classified as vulnerable.
