Reinforcing Local Food Security through Agrogeological Perspectives: South Lampung, Indonesia

Abstract

Local food security is a critical priority for the coming decades, especially in Indonesia. As the population grows, it is essential to meet local food needs before taking part in the national supply. South Lampung, a key region in Sumatra, plays a vital role in the nation’s food supply. However, rapid population growth in this area has raised concerns about the conversion of agricultural land to residential use. To address these challenges, this study raises agrogeology as an alternative approach to reinforcing local food security. By re-evaluating the regional geological characteristics, the study aims to understand the distribution of productive, traditional paddy fields. Field surveys and spatial analyses were conducted for this study. The findings reveal that the silicate-rich lithology in the region’s pyroclastic deposits significantly contributes to maintaining fertile soils, particularly in areas such as Candipuro, Jatiagung, and Palas. Natural drainage systems further support rice cultivation. In alignment with the Sustainable Development Goals, the agrogeological perspective emphasizes the need to mitigate land conversion and improve land-use planning. This approach offers a sustainable pathway to enhance paddy field productivity and ensure water and nutrient availability, thereby supporting long-term local food security.
