Abstract

The rapid urban growth in Banjarbaru City has significantly impacted the quality and quantity of green open spaces. Fragmentation of green spaces poses a major challenge in maintaining the city's ecological balance, particularly amidst high urbanization rates. This study aims to analyze the distribution and fragmentation level of green spaces across five sub-districts in Banjarbaru City using drone technology and spatial approaches. Data were collected through high-resolution aerial mapping and spatially analyzed to identify fragmentation patterns and compare them with the 2024-2043 Spatial Planning (RTRW) of Banjarbaru City. The results show that the highest fragmentation occurs in the Landasan Ulin and South Banjarbaru sub-districts, characterized by small patches and low core vegetation areas. Meanwhile, North Banjarbaru, Cempaka, and Liang Anggang sub-districts still retain extensive and connected green spaces. A comparison with the RTRW reveals a deviation between the planned and actual conditions, particularly in areas designated to be preserved as green open spaces.

Abstract

The ongoing land-use conversion in Banjarbaru City has significantly reduced agricultural areas, potentially threatening local food availability and the achievement of food security. This study aims to identify the distribution of idle land and assess its potential utilization as an alternative for agricultural development in urban areas. The methodology integrates drone imagery for mapping uncultivated land, agricultural and biophysical statistical data, and community perception surveys to evaluate readiness and constraints in managing idle land. The results show that idle lands are spread across all districts, with the highest concentration in South Banjarbaru and Landasan Ulin. These areas exhibit high potential for the development of horticultural crops and lowland rice cultivation, although technical interventions such as soil rehabilitation and improved water access are required. In conclusion, optimizing the utilization of idle land in Banjarbaru City can serve as an effective strategy to enhance local food production and strengthen area-based food security.
