Rampant deforestation in Leuser triggers floods, landslides - National - The Jakarta Post
The rampant destruction of forests in the Leuser ecosystem, a major water source for Aceh, has led to frequent flooding in the province.
A team from the Leuser Conservation Forum (FKL) performed a ground check on damaged areas in the ecosystem and found that, in 2018, about 5,685 hectares of the ecosystem were deforested, with the most serious damage found in Gayo Lues with 1,063 ha of deforested area.
The ecosystem, located across several regencies in the province, also saw 889 ha damaged in Nagan Raya and another 863 ha in East Aceh. As of December 2018, 1.7 ha of forest remained in the Leuser ecosystem.
The FKL and another conservation group, the Aceh Forest, Nature and Environment Foundation (Haka), concluded from their observations that the high rates of deforestation over many years caused flooding.
Based on an observation of river basin areas, the highest rate of deforestation was found in the Singkil-Alas River Basin, which covers Gayo Lues, Southeast Aceh, Subulussalam, Aceh Singkil and the neighboring province of North Sumatra.
