An occupation that can disrupt the ecosystem occurs in the customary forest of Kampung Sereh, part of the Cycloop Mountains Area of ​​Papua, Indonesia. The occupation of customary forests in urban areas, especially Sentani District, the capital of Jayapura Regency, is the main topic of this study.

Using field observation methods and spatial analysis, Landsat and Sentinel satellite imagery from 2008 to 2023, revealed a significant increase in residential and agricultural land and a decrease of around 37% in previously customary forests. This degradation increases the risk of ecological disasters, which endanger ecosystem services for biodiversity, soil erosion, and water supply. For the preservation of customary forests in urban areas.
