As the largest coastal ecosystem in East Kalimantan, the Mahakam Delta area has an area of about 1,500 km2. The area includes mangroves that grow on 92 islands (deltas) and mangrove areas that grow on the mainland of Kalimantan. With the largest area of Nipah cover in the world, the Mahakam Delta ecosystem has a very high biological productivity and gets a potential supply of organic material as nutrients from the upper land through the Mahakam rivers flow along more than 980 km. Therefore, this ecosystem has considerable fishing resource potential (fish, shrimp, and crabs) (KPHP Delta Mahakam).
Having extensive forest resources undeniably requires serious and thorough attention so that its functions and benefits can continue to be maintained and even improved. One of the things that can be done is monitoring mangrove forests periodically by involving communities directly.
GLAS Allert together with the Titian GIS Team created a map of the latest deforestation based on satellite imagery, then Titian distributed it to the Forest Farmers Group (KTH) involved in monitoring activities for verification.
In the results of the latest survey in 3 sub-districts in the Mahakam Delta, some passive ponds were found to have been filled with several kinds of mangrove vegetation but were cut down / burned / poison to be used as active ponds.
