Climate Change Impact Analysis on Food Availability in the Province of Kalimantan Utara, Indonesia

Abstract

Climate change directly affects crop yields as a measure of food availability by, e.g., causing harvest causing harvest failure. El Niño and La Niña are two weather patterns that affect the climate of Indonesia, a country at low latitudes, and reportedly increase its vulnerability to food insecurity. This study was designed to analyze the impact of climate change on food availability in the Province of Kalimantan Utara using secondary data (i.e., temperature, rainfall, and agricultural production) as the base data. This study employed quantitative descriptive analysis to explain the results expressed in maps, tables, and graphs and the regression technique to determine the impact of climate change on food availability. Regression analysis revealed that climate change significantly shaped the availability of rice (0.008) and vegetable commodity (0.000) but posed insignificant effects on tubers, legumes, and fruits. Apart from climate change, food availability also depends on land management, land suitability, capital, technology, and cultivated plant variety.
