Abstract

Mitigation actions to address climate change are essential to prevent future adverse impacts, with woody species in forests playing a pivotal role in carbon storage, as exemplified by the agroforestry systems commonly practiced in community forests of Bogor Regency, which integrate woody species and crops. This study aimed to analyze changes in vegetation density using the Normalized Difference Vegetation Index (NDVI) approach, analyze stand structure and composition, and estimate above-ground carbon stocks in the agroforestry land of community forest in Tenjolaya Sub-District, Bogor Regency. The methods used were spatial analysis with NDVI, vegetation analysis, and carbon stock estimation using allometric and destructive methods. The plot size was 50 m × 50 m, totaling 21 plots. NDVI analysis resulted in low density (0.59–0.67), moderate density (0.67–0.78), and high density (0.78–0.85). This study found 178 plant species across 40 families, with Fabaceae and Myrtaceae being the most dominant. The carbon stock is 27.69 tons carbon/ha. Carbon stock is significantly influenced by tree density, number of species, and basal area values. A well-managed community forest has high ecological, economic, and social potential through the development of agroforestry, which can maintain biodiversity and environmental sustainability while storing carbon stocks. Keywords: above-ground carbon, agroforestry, community forest, normalized difference vegetation index, vegetation density

Abstract

Forest and land fires have become an annual occurrence in South Papua Province over the past decade, with Mappi District identified as a fire-prone hotspot. This study analyzes hotspot trends and dynamics from 2012 to 2021 and estimates burned areas using Terra/Aqua Moderate Resolution Imaging Spectroradiometer (MODIS)satellite data and ArcMap 10.8. The highest number of hotspots was recorded in 2015 (3,879), with 36.5% occurring on peatland and 63.5% on mineral soils. A historical hotspot analysis pinpoints the prevalence of fire incidents between July and October, highlighting the necessity for intensified prevention measures before July. Furthermore, a significant linear regression is established between annual hotspot numbers and rainfall in Mappi District (p-value = 0.006), signifying the impact of climatic factors on fire occurrences. The largest burned area, estimated at 134,051.74 hectares, also occurred in 2015, coinciding with a strong El Niño event. More importantly, these fires occurred not only on mineral soil but also on peatland areas. Hence, this study highlights the critical need to prioritize comprehensive forest and land fire management in Mappi District, South Papua Province.
