Indonesia is currently being hit by a food crisis. Through the State Revenue and Expenditure Budget, which was realized from the 2022 defense budget, the Ministry of Agriculture has allocated funds amounting to IDR92.2 trillion for national food security. Since the COVID-19 epidemic, the average consumption of rice per capita per week in Indonesia has increased, reaching 1404 kg since 2018. In response to this problem, the government has taken the initiative to create a Food Estate Program. However, this initiative has not produced the expected results. On the contrary, it is causing a social and ecological disaster that is detrimental to natural resources and residents in the Gunung Mas forest, Central Kalimantan. A growing problem is that the Food Estate Program has implications for weak sustainable development. Moreover, although cassava is not a staple food for residents, the community’s customary forests have already been cut down to make way for food estate areas for cassava farming. The traditional wisdom of planting vegetables in intercropping forests has been disrupted, so that the Dayak community is becoming food insecure and may become poor. This chapter analyzes the socio-ecological crisis caused by the Food Estate Program and shows how it links to the food crisis in the context of sustainable development. This research uses qualitative methodology with analytical descriptive analysis.
