Abstract

Ibu Kota Nusantara will be a significant smart sustainable forest city regarding climate change. Calculation of land-based carbon emission reduction performance in the IKN based on land cover maps through visual interpretation of medium-resolution satellite imagery sensing experiences uncertainty that follows a gradual process. In estimating emissions in this IKN, it is related to the uncertainty of land-based carbon emission activity data. This study aims to obtain the value of uncertainty in activity data from the dynamics of land cover changes in the IKN. The methodology used in this study is the interpretation of medium-resolution satellite imagery, and land cover changes using 5 (five) classes of change, namely deforestation, forest degradation, forest gain, stable forest, and stable non-forest, sampling design using stratified random sampling with the proportional allocation method. The results of the sample interpretation are then calculated for accuracy (user's accuracy, producer's accuracy, and overall accuracy) and uncertainty with a confusion matrix/error matrix. This study shows that changes in deforestation land cover produce high uncertainty values ​​(> 15%), this is because most of the samples for changes in deforestation land cover are in stable non-forest land cover changes, in actual the reference data from image data with high-resolution imagery does not match. While changes in stable forest and stable non-forest land cover throughout the year produce low uncertainty values ​​(≤15%), most of the samples for stable forest and stable non-forest land cover change conditions match in the diagonal column which shows that there is a match between the data class of land cover change classification results and reference data from high-resolution image data.

Abstract

Land tenure issues in forest areas are strategic issues in the context of sustainable development, agrarian reform, and social justice-based natural resource management. This study analyses the land tenure settlement policy in the context of forest area management in Kampung Bukit Makmur and management in Kampung Labanan Makarti, Berau Regency, East Kalimantan. The method of this research using qualitative approach with document study techniques, in-depth interviews, and participatory observation. The analysis was conducted using a public policy framework, tenure approach, and principles of good governance. The results show that the implementation of the Land Tenure Settlement in Forest Areas (PPTKH) policy was arranged by Presidential Regulation No. 88/2017 there are challenge remains at the local level, including: unsuitability between forest area mapping and the reality of land use by public, the weakness coordination between government agencies, limited accurate spatial data, and less of community participation on the inventory and verification process. Nevertheless, there are strategic opportunities to encourage fair and sustainable settlements through the utilization of forest area release schemes, social forestry, and integration with agrarian reform policies. This recommendation of this study need reinforcement from local institutions, acceleration of participatory mapping, increasing community capacity, and need to create formula of technical policies that are responsive to local social-ecological conditions. Settlement of land tenure in forest areas does not only concern on legal-formal aspects, but also include on the dimensions of social justice, acknowledgment of the rights of indigenous/local communities, and preservation of the ecological functions of forest areas.
