Abstract

Environmental degradation in the Bila Watershed, characterized by increasing critical land, carbon emissions, erosion, and sedimentation in Lake Tempe, requires integrated low-emission land-use planning. This study aims to analyze carbon stocks, carbon dioxide (CO₂) sequestration, sedimentation, and economic valuation under several land-use scenarios using the Land Use Planning for Low Emission Development Strategy (LUWES) approach. The novelty of this study lies in the integration of critical land analysis, carbon stock estimation, sedimentation assessment, and economic valuation into low-emission watershed planning scenarios. The research was conducted in the Bila Watershed, South Sulawesi Province, covering an area of 179,612.87 ha during the 2016–2017 period. Biomass measurements were conducted using nested plots across representative land-cover classes, while erosion was estimated using the Universal Soil Loss Equation (USLE) and sedimentation was calculated using the Sediment Delivery Ratio (SDR) approach. Economic feasibility was analyzed using the Net Present Value (NPV) method. Three land-use scenarios were simulated over a 20-year planning horizon. The results indicate that the existing condition produced carbon emissions of 915,537.49 tons CO₂-eq and estimated sedimentation of 396,163.05 tons/year. Scenario I provided the best ecological-economic balance by increasing carbon stocks, reducing erosion and sedimentation by 45.93%, and increasing economic value by 10.66%. Scenario II generated the highest economic return but increased ecological pressure, while Scenario III emphasized social forestry and emission reduction with moderate economic benefits. These findings demonstrate that integrated low-emission watershed planning can support critical land rehabilitation, climate change mitigation, and sustainable watershed management.

Abstract

The issue of environmental degradation and the reduction of green open spaces in urban areas poses a significant challenge to ecosystem sustainability and community food security. One of the main causes of this is land-use change, including in mosque areas. Generally, mosque land is covered with concrete or paving to be used as parking lots, thus losing its ecological function. This condition encourages the need for an environmentally-based empowerment approach rooted in religious values. Therefore, the community service activity carried out was the Implementation of Mosque-Based Ecotheology Through the 10,000 Trees Movement as a form of ecotheology application to the community in South Sulawesi Province. The goal of this activity was to integrate Islamic teachings on nature conservation with sustainable agricultural practices by planting productive fruit trees around the mosques. The implementation method consisted of four stages: seedling and site preparation, planting, monitoring of tree growth, and evaluation of social and environmental impacts. This activity was carried out in 40 mosques with the involvement of PRIMA DMI Sulsel, the Ministry of Religious Affairs of the Republic of Indonesia, Project Dakwah, and Phinisi ID, through a series of events: the Grand Opening, Sharing Happiness, and Mosque Safari. The results of the activity demonstrated the active participation of congregations and mosque administrators, demonstrated by the involvement of 40 beneficiary mosques in the tree planting and maintenance process, as well as the willingness of mosque administrators to provide planting space and monitor seedling growth. Four productive tree species—figs, longans, breadfruit, and limes—were successfully distributed and planted at the target locations. This initiative successfully strengthened local food security and expanded the mosque's role as a centre for sustainable environmental outreach.
