Study monitors mangrove changes in Buru Island, supporting sustainable coastal management.
The area and density of mangrove forests in Teluk Kayeli, Buru Island, continue to degrade due to land conversion and anthropogenic activities, necessitating spatial monitoring to support sustainable management. This study uses PlanetScope satellite imagery with a spatial resolution of 3 meters for the periods 2016, 2021, and 2026, with Normalized Difference Vegetation Index (NDVI) analysis to measure the coverage and density of mangrove vegetation. The results show a decrease in mangrove vegetation area from 29.06 km² in 2016, 26.40 km² in 2021, and 24.02 km² in 2026. NDVI density analysis indicates that in 2016, mangroves with rare density covered 0.41 km², in 2021, 0.41 km², and in 2026, 1.94 km². Mangroves with medium density covered 4.60 km² in 2016, 4.98 km² in 2021, and 3.12 km² in 2026. Mangroves with dense density covered 23.67 km² in 2016, 23.67 km² in 2021, and 18.96 km² in 2026. Monitoring mangroves based on PlanetScope imagery and NDVI has proven effective for early detection of spatial changes, thus it is recommended to be integrated into mangrove conservation and restoration strategies to support sustainable management in the coastal areas of Buru Island.
