“…The Sundarbans, the largest contiguous mangrove forest in the world [9,10], is considered as a site of national and international importance for the conservation of biodiversity [11,12]. The Sundarbans covers an area of approximately 10,000 km 2 and lies in the territory of Bangladesh and India [9,13]. This forest has enormous ecological and economic importance at local, national and global scales [11].…”

“…According to Donato et al [17] and Rodda et al [18], mangroves are the most carbon-rich forests in the tropics. Despite their small spatial extent, mangroves are considered as an important resource around the world due to their ability to store and sequester carbon, compared to many freshwater wetlands [2]. The Sundarbans absorbs 469.2 to 569.2 Mega grams of carbon per hectare [17,19].…”

Abstract:The Sundarbans mangrove forest is an important resource for the people of the Ganges Delta. It plays an important role in the local as well as global ecosystem by absorbing carbon dioxide and other pollutants from air and water, offering protection to millions of people in the Ganges Delta against cyclone and water surges, stabilizing the shore line, trapping sediment and nutrients, purifying water, and providing services for human beings, such as fuel wood, medicine, food, and construction materials. However, this mangrove ecosystem is under threat, mainly due to climate change and anthropogenic factors. Anthropogenic and climate change-induced degradation, such as over-exploitation of timber and pollution, sea level rise, coastal erosion, increasing salinity, effects of increasing number of cyclones and higher levels of storm surges function as recurrent threats to mangroves in the Sundarbans. In this situation, regular and detailed information on mangrove species composition, their spatial distribution and the changes taking place over time is very important for a thorough understanding of mangrove biodiversity, and this information can also lead to the adoption of management practices designed for the maximum sustainable yield of the Sundarbans forest resources. We employed a maximum likelihood classifier technique to classify images recorded by the Landsat satellite series and used post classification comparison techniques to detect changes at the species level. The image classification resulted in overall accuracies of 72%, 83%, 79% and 89% for the images of 1977, 1989, 2000 and 2015, respectively. We identified five major mangrove species and detected changes over the 38-year (1977-2015) study period. During this period, both Heritiera fomes and Excoecaria agallocha decreased by 9.9%, while Ceriops decandra, Sonneratia apelatala, and Xylocarpus mekongensis increased by 12.9%, 380.4% and 57.3%, respectively.

Mangrove restoration is really needed for restoring its ecosystem functions ABSTRAKRestorasi mangrove sangat diperlukan untuk mengembalikan fungsi-fungsi ekosistemnya, sehingga mampu menunjang aktivitas perikanan dan melindungi pesisir dari cuaca esktrim. Mangrove mampu mengakumulasi sedimen yang bermanfaat bagi perlindungan area pesisir dari kenaikan muka air laut. Untuk itu, studi ini bertujuan untuk mengkaji laju akumulasi sedimen di area mangrove pasca restorasi. Lokasi pengambilan sampel dibagi menjadi 3 stasiun berdasarkan umur restorasi, yaitu umur ≥ 15 tahun (Stasiun 1), umur 4 -10 tahun (Stasiun 2) dan umur 2-8 tahun (Stasiun 3). Pengambilan inti sedimen dilakukan dengan menggunakan pipa polyvinyl chloride yang berdiameter 7,6 cm dan panjang 100 cm. Laju sedimentasi diukur dengan menggunakan analisis radionuklida Pb-210. Hasil penelitian menunjukkan rata-rata laju akumulasi sedimen dalam 20 tahun terakhir dari seluruh stasiun berkisar antara 0,17 -0,42 g/cm 2 tahun. Laju sedimentasi tertinggi terdapat di stasiun retorasi yang berumur paling tua sedangkan laju sedimentasi terendah berada di stasiun restorasi termuda. Proses restorasi secara jelas mampu mengembalikan peran mangrove dalam memerangkap sedimen di area pesisir.Kata kunci: akumulasi sedimen, restorasi mangrove, Teluk Lembar-Pulau Lombok

“…Di Indonesia, sektor penggunaan lahan menyumbang 65% dari total emisi nasional (Krisnawati, 2010). Penurunan laju deforestasi dan pembangunan hutan tanaman, baik pada lahan kering (terestrial) maupun lahan basah (wetland) merupakan upaya penting untuk mengurangi emisi dan konsentrasi gas rumah kaca (GRK) di atmosfir (Devi et al, 2013;Marchio, Savarese, Bovard, & Mitsch, 2016;Wibowo, 2010).…”

ABSTRAKHutan tanaman industri yang dibangun pada lahan terdegradasi seperti semak belukar dan padang rumput dapat meningkatkan serapan karbon pada lahan tersebut. Penelitian ini bertujuan untuk menilai serapan karbon hutan tanaman krasikarpa (Acacia crassicarpa) yang dibangun pada lahan rawa terdegradasi di Kabupaten Ogan Komering Ilir (OKI), Sumatera Selatan. Penelitian dilakukan dengan menganalisa data dari 433 petak ukur permanen yang dibangun pada berbagai tipe lahan basah, diantaranya tipe lahan endapan liat (marine clay), gambut dangkal (peat VI) dan gambut dalam (peat VII). Petak-petak pengukuran ini diukur dari tahun 2005 sampai tahun 2014. Hasil penelitian menunjukkan bahwa model serapan karbon berbeda pada masing-masing tipe lahan basah, yaitu Y = 34,82/(1+77,71 exp (-1,44 X)) pada tipe lahan endapan liat, Y = 28,05/(1+17,64 exp (-0,96 X)) dan Y = 25,52/(1+ 40,89 exp (-1,47 X)) pada tipe lahan gambut dangkal dan gambut dalam. Berdasarkan model tersebut, serapan karbon maksimum berbeda pada tiap tipe lahan, yaitu sebesar 34,82 ton C/ha pada lahan endapan liat; 28,05 ton C/ha pada gambut dangkal (peat VI) dan 25,52 ton C/ha pada lahan gambut dalam (peat VII). Riap serapan rata-rata maksimum pada lahan endapan liat dan gambut dangkal terjadi pada umur 4,25 tahun sebesar 7,0 dan 5,08 ton C/ha/tahun, tetapi pada tipe lahan gambut dalam terjadi lebih dulu yaitu pada umur 3,75 tahun sebesar 5,89 ton C/ha/tahun. Kata kunci: Acacia crassisarpa, serapan karbon, hutan gambut, lahan rawa terdegradasi, petak ukur permanen ABSTRACTThe industrial forest plantation developed on degraded wetland such as shrub and grassland areas could improved the carbon sequestration in the lanscapes. This research was aimed to assses the carbon sequestration of Krasikarpa (Acacia crassicarpa A. Cunn ex Benth.) plantation developed on various types of degraded wetland in Ogan Komering Ilir (OKI) district, South Sumatera. The research was conducted by analyzing data from 433 permanent sample plots that constructed on various wetland types consist of marine clay, shallow peat (peat VI), and deep peat (peat VII). The plots have been measured from 2005 to 2014. The result showed that carbon sequestration models are significantly different based on the wetland types, i.e Y = 34,82/(1+77,71 exp (-1,44 X)) on marine clay, Y = 28,05/(1+17,64 exp (-0,96 X)) and Y = 25,52/(1+ 40,89 exp (-1,47 X)) on shallow peat and deep peatland respectively. Based on the model, the maximum carbon sequestration was different on each wetland type, amounted at 34,82 ton C/ha on marine clay; 28,05 ton C/ha on shallow peat (peat VI) and 25,52 ton C/ha on deep peat (peat VII). The maximum mean annual of carbon sequestration on marine clay and peat VI occured in the age of 4,25 year, amounting of 7,0 and 5,08 ton C/ha/year but on peat VII occured earlier i.e at the age of three year amounted at 5,89 ton C/ha/year.
