Abstract Land fires are an annual problem in Indonesia, and the province that experiences land fires almost every year is South Kalimantan. Various factors contribute to land fires, including climatic conditions, human activities, and environmental factors. This study was conducted in the floodplains of the Barito and Negara Rivers, specifically in Hulu Sungai Selatan Regency. This study was conducted by observing the biophysical conditions at the research location, including topography, climate, and land cover. The collected data was subsequently used to develop programs to prevent land fires. The biophysical analysis results indicated that the land studied has flat topography with a slope of less than 8%. The soil is primarily composed of alluvial deposits and peat. The climate in this area is tropical, characterised by five months of wet conditions and seven months of dryness. Land cover is dominated by dry land agriculture (54%) and swamp shrubs (13%). The findings indicated that areas inundated during the rainy season facilitated the healthy growth of shrubs, which made land clearing through burning necessary. In response to this challenge, the palm oil company, in collaboration with the government and the Fire Aware Community (MPA), took proactive measures by constructing dams to mitigate flooding during the rainy season. As a result, the construction of the dams successfully protected the land from flooding, enabling agricultural activities to be carried out throughout the year and reducing the incidence of land fires.
