Spatial Analysis of Mangrove Change and Rehabilitation Guidelines in the North Coast Area of West Java Province, Indonesia

Abstract

The mangrove ecosystem at the global level has currently experienced many changes in other functions, causing an imbalance in coastal ecosystems. Time series spatial analysis of mangrove changes in the northern coastal areas of West Java Province is important to identify areas that have experienced deforestation within a certain period of time and determine the direction of their rehabilitation. A spatial approach is used to determine the distribution of mangrove forest logging locations so that they can be seen clearly using time series satellite imagery. The suitability of land for mangrove rehabilitation is determined based on physical conditions and planting techniques, taking into account land use and existing land status. The results of the spatial analysis show that the northern coastal area of West Java has experienced changes in mangroves; the area of mangroves in this location increased from 1,616.35 ha in 2001 to 3,122.56 ha in 2022. Although the overall area of mangroves in the study area has increased, there are 9 districts experiencing deforestation and requiring rehabilitation. Areas experiencing deforestation based on land suitability analysis are included in the categories of very suitable, suitable, and in accordance with conditions. The types recommended for planting include Avicennia sp., Rhizophora sp., Bruguier sp., Acrostichum sp., Sonneratia sp., and Nypa fruticans. Mangrove rehabilitation can be carried out in three ways, namely: in aquaculture areas with a silvofishery system, on riverbank land with planting to form green belts, and in residential areas, planting in locations directly adjacent to the coast and fish farming areas, in the direction of the coast. directed. is still a green belt zone with a range of 52-702 m perpendicular to the coastline. It is hoped that with the mangrove rehabilitation activities carried out, the area on the North Coast of West Java Province can be sustainable.
