Abstract

Forest fires have become a regular phenomenon in Indonesia, especially in the dry season. They can be caused by natural and anthropogenic factor. Since Indonesia’s soil, especially Sumatra and Kalimantan, is a peatland type, this type of soil is highly inflammable, thus a small fire can easily spread and become massive. This phenomenon provenly disturbs the balance of the ecosystem and socio-economy of the affected country. Previous forest fires resulted in a higher risk of respiratory problems and increased mortality or the death of infants and children. The loss of biodiversity and the increasing amount of Green House Gas (GHG) Emissions that affected the change of climate is also the effect caused by those.  For those reasons, the need of monitoring forest fires is essential, especially in climate change mitigation as fire disturbance is one of the key variables in it. This paper will further discuss the method of monitoring through burned area mapping using remote sensing techniques.

Abstract

Forest fire is a hazard that common to happen in Indonesia every year, whether from natural or human-induced factor. These fires can be uncontrollable and destruct the forest. Furthermore, these can affect the health of the people, the biodiversity, the disruption in transportation and the socioeconomic of the affected region. The total area calculated was burned is 875.756 hectares in the entire country in 2019, the biggest lost after 2015. Thus, the study conducted in some affected area in Riau Province, Sumatra, Indonesia where consistently suffered from the fire by remote sensing and GIS approach. The study of the burned area was investigated using a formulated index called NBRI (Normalized Burn Ratio Index) based on Near Infrared (NIR) and Shortwave Infrared (SWIR) spectral reflectance of Landsat 8 OLI/TIRS Satellite Imageries. The two values of NBRI from post and pre-fire images were calculated to define differenced NBR (dNBR) to assess its severity. It is found that about 4,7 %, or about 11.014 hectares of the area of the study which was about 234.864 hectares was burned. 90,3 % of the burned area was located in the vegetated area, especially forest area with 50,25 % of those cover the burned area. The validation was using visual interpretation based on SPOT 7 pansharpened images resulted in acceptable agreement with kappa coefficient value of 0,83. The information on the maps can be used to develop rehabilitation planning or predict the area for potential fire hazard in the future.
