Ekosistem mangrove mengalami tekanan dan penurunan jasa lingkungan diduga karena abrasi dan fenomena alam serta aktivitas masyarakat seperti penggalian pasir di pesisir pantai. Pemerintah telah melakukan upaya konservasi hutan mangrove dengan cara penanaman kembali, namun belum berhasil. Salah satu permasalahan adalah belum atau tidak adanya informasi nilai ekonomi mangrove sebagai dasar penentuan program konservasi. Penelitian ini bertujuan mengetahui nilai ekonomi ekosistem mangrove di pesisir Laut Arafura meliputi 3 distrik yaitu Malind, Merauke dan Naukenjerai. Metode yang digunakan yaitu TEV (Total Economic Value) yang terdiri dari analisis nilai guna langsung menggunakan harga pasar. Nilai guna tidak langsung dan nilai pilihan menggunakan benefit transfer. Nilai non guna yang terdiri dari nilai keberadaan dan nilai pewarisan menggunakan WTP (willingness to pay). Hasil penelitian menunjukkan bahwa nilai ekonomi hutan mangrove di kawasan pesisir pantai Laut Arafura per tahun sebesar Rp. 213.344.656.759,00 (213 Milyar Rupiah) atau setara dengan Rp. 21.075.240,00/ha/tahun atau setara dengan Rp. 8,6 juta rupiah per kepala keluarga. Title: Economic Valuation In The Coastal Mangrove Ecosystem District MeraukeEcosystem mangrove in Araufra Coastal had underpressure and decreasing environmental services because of abration as natural phenomena, and unsuistainable community activities such as digging sand on the coast. The Government has made the conservation of mangrove forests by replanting, but has not succeeded. One of the problems is not yet or absence of information about the economic value of mangroves as the basis for determining the conservation program. This study aims to determine the economic value of the mangrove ecosystem in the Arafura Sea coast in three districts: Malind, Merauke and Naukenjerai. The methodology using TEV (Total Economic Value) consisting of direct use value analysis using market prices. Indirect use values and the options value using the benefits transfer. Non-use value consist the existence and bequest value using WTP (willingness to pay). The result showed that the economic value of mangrove forests in the coastal regions of the Arafura Sea is Rp. 213.344.656.759,00 (213 billion rupiah per year) or equivalent with Rp. 21.075.240,00/ha/year, or equivalent with Rp. 8,6 million per household.

The mangrove ecosystem of Sundarbans region plays an important ecological and socio-economical role in both India and Bangladesh. The ecological disturbance in the coastal mangrove forests are mainly attributed to the periodic cyclones caused by deep depression formed over the Bay of Bengal. In the present study, three of the major cyclones in the Sundarbans region were analyzed to establish the cause-and-effect relationship between cyclones and the resultant ecological disturbance. The Moderate Resolution Imaging Spectroradiometer (MODIS) time-series data was used to generate MODIS global disturbance index (MGDI) and its potential was explored to assess the instantaneous ecological disturbance caused by cyclones with varying landfall intensities and at different stages of mangrove phenology. The time-series MGDI was converted into the percentage change in MGDI using its multi-year mean for each pixel, and its response towards several cyclonic events was studied. The affected areas were identified by analyzing the Landsat-8 satellite data before and after the cyclone and the MGDI values of the affected areas were utilized to develop the threshold for delineation of the disturbed pixels. The selected threshold was applied on the time-series MGDI images to delineate the disturbed areas for each year individually to identify the frequently disturbed areas. The classified intensity map could able to detect the chronically affected areas, which can serve as a valuable input towards modelling the biomigration of the invasive species and efficient forest management.
