Peatlands are highly important ecosystems in terms of its services and
functions such as provision of habitat, retention of biodiversity, water availability
and maintaining high carbon stocks. Out of the global peatland area a considerable
portion (more than 11%) is found in tropics particularly insular Southeast Asia.
The peatlands in Indonesia are of particular importance because of its unique
pedogenesis and distinct topography. These peatlands today in its natural settings
are found as Peat Swamp forests where the peat forming processes are still
continued; and where the above ground biomass is found as trees unlike temperate
peatlands where the source of organic carbon in soil and above ground biomass
are lower plants (pteridophytes). Over the last three decades peatlands are
extensively developed for oil palm plantations making Indonesia one of the largest
producers of palm oil. Thus, due to these developments the sector is contributing
excellently to national economy and improving livelihoods of local people. The
expansion of oil palm plantations is a large scale land use change and is having
several dynamics. The land use changes and development of peatlands for oil
palm plantations is a gradual process and to explore its history and expansion
current research was designed to achieve the following objectives. Lahan gambut adalah ekosistem dengan fungsi dan kegunaan yang sangat
penting seperti sebagai penyedia habitat serta konservasi keanekaragaman hayati,
ketersediaan air dan cadangan karbon yang tinggi. Dari luas total lahan gambut
global, sebagian besar (lebih dari 11%) ditemukan di daerah tropis terutama di
Asia Tenggara. Di Indonesia, lahan gambut memiliki karaktristik spesifik karena
proses pedogenesis dan topografinya yang unik. Saat ini, pada kondisi alaminya,
lahan gambut di Indonesia ditemukan dalam bentuk hutan rawa gambut (PSF),
proses pembentukan gambutnya masih berlanjut dengan biomassa atas tanah
(AGB) berupa pepohonan, tidak seperti lahan gambut di daerah beriklim sedang
yang sumber karbon organik tanah dan AGBnya adalah tumbuhan paku-pakuan
(Pteridophytes).
