Integration of GIS and Remote Sensing for Hotspot Distribution Analysis in Berbak Sembilang National Park

This paper describes hotspot distribution during 2000-2018. The study was conducted in Jambi and Sumatra Selatan Provinces, located in Berbak Sembilang National Park (TNBS) at 1°08’- 1°43’ LS, 104°05’ -104°26’ BT and 1°08’ -1°41’ LS, 104°15’-104°15’ BT. The study area was approximately 200,000 hectares, mostly covered by peat lands. The main objective of the paper is to determine the distribution of fire occurrence based on historical hotspot data during an 18 year period (2000-2018), with analysis of land cover and land use trajectories after the occurrence of fire in the park. The data used include hotspot data obtained using Getis-Ord-Gi*. The results show that the total number of hotspots observed in the 2000-2018 period in TNBS was 32,501, of which 12,084 had a probability at the 80% confidence level of fires occurring on peat land every year, either during La Niña period. Distribution by land use and land cover showed the highest distribution of hotspots in mixed field land use (51.78%), fields (41.35%), plantations (26.06% whereas in TNBS Land cover in primary swamp forest (0.45%), secondary swamp forest 1.74%. In conclusion, hotspot distribution was mostly in land use areas and the associated fires were utilised by farmers and companies (forest plantation) for land preparation around TNBS.`
