Abstract
The objective of this research was to detect changes in forest areas and, subsequently, the potential forest area that can be extended in the South Sumatra province of Indonesia, according to the Indonesian forest resilience classification zones. At first, multispectral satellite remote sensing datasets from Landsat 7 ETM+ and Landsat 8 OLI were classified into four classes, namely urban, vegetation, forest and waterbody to develop Land Use/Land Cover (LULC) maps for the year 2003 and 2018. Secondly, criteria, namely distance from rivers, distance from roads, elevation, LULC and settlements were selected and the reclassified maps were produced from each of the criteria for the land suitability analysis for forest extension. Thirdly, the Analytical Hierarchy Process (AHP) was incorporated to add expert opinions to prioritize the criteria referring to potential areas for forest extension. In the change detection analysis, Tourism Recreation Forest (TRF), Convertible Protection Forest (CPF) and Permanent Production Forest (PPF) forest zones had a decrease of 20%, 13% and 40% in area, respectively, in the forest class from 2003 to 2018. The Limited Production Forest (LPF) zone had large changes and decreased by 72% according to the LULC map. In the AHP method, the influential criteria had higher weights and ranked as settlements, elevation, distance from roads and distance from rivers. CPF, PPF and LPF have an opportunity for extension in the highly suitable classification (30%) and moderately suitable classification (41%) areas, to increase coverage of production forests. Wildlife Reserve Forests (WRFs) have potential for expansion in the highly suitable classification (30%) and moderately suitable classification (52%) areas, to keep biodiversity and ecosystems for wildlife resources. Nature Reserve Forests (NRFs) have an opportunity for extension in the highly suitable classification (39%) and moderately suitable classification (48%) areas, to keep the forests for nature and biodiversity. In case of TRF, there is limited scope to propose a further extension and is required to be managed with collaboration between the government and the community.
Highlights
Indonesia has been losing up to 2 million hectares of land annually, mainly due to illegal cutting and land conversion [1]
Remotely sensed data were used to monitor the changes in the Land Use/Land Cover (LULC) and quantify the differences in the forest classes in the South Sumatra province of Indonesia from 2003 to 2018
In the LULC analysis, sic types of forest zones: Convertible Protection Forest (CPF), Permanent Production Forest (PPF), Limited Production Forest (LPF), Wildlife Reserve Forests (WRFs), Tourism Recreation Forest (TRF) and Nature Reserve Forests (NRFs) were focused upon to find out their changes and locate potential areas for extension of forest
Summary
Indonesia has been losing up to 2 million hectares of land annually, mainly due to illegal cutting and land conversion [1]. Deforestation rates have increased throughout Indonesia due to urbanization and palm oil plantations covering 5,418,413 ha [4]. Forest fires, poor forest management practices and an increasing demand for forest products and agriculture contribute to the damage of forests, which are more severe in the South Sumatra province of Indonesia. Many forests in South Sumatra have recently experienced high rates of deforestation due to human migration and the expansion of agriculture or industry. Land-use planning has not taken place over time to align the changes in forest resources according to the Indonesian forest resilience classification. In Indonesia, there are six types of forest classification zones, defined by the Indonesian forest resilience system: Tourism Recreation Forest (TRF), Convertible Protection Forest (CPF), Permanent Production Forest (PPF), Limited Production
