“…This scenario will reflect the improved socio-environmental awareness, and the local people will appreciate the protective role of mangroves in mitigating climaterelated hazards. Studies show that the productive lifespan of aquaculture ponds on the fringes of mangroves is relatively short (see Aslan et al 2021). In such cases, the abandoned ponds or uneconomical ponds can be restored into mangrove plantations after necessary amendments.…”

Mangrove habitats play a vital role in balancing the coastal ecosystems by providing an array of provisioning, regulating, cultural, and supporting ecosystem services. Despite several conservation measures taken to protect mangroves, they have been facing economic, socio-environmental, and climatic threats. There is a need to quantify the mangroves' ecosystem services (ES), especially in developing and under-developed nations, to fasten up the mangrove conservation. To address this issue, in the present study, we quantified the ES of the mangroves in Odisha State on the eastern coast of India. And we projected the changes in ES according to the plausible future land-use changes using scenario analysis. The plausible future scenarios (by 2030) have been generated based on the participatory surveys and key informant interviews from the stakeholders in the region. The scenarios encompass socio-economic development, infrastructural development, mangrove conservation, agriculture and aquaculture expansion, and climate change. Coastal blue carbon sequestration, sediment retention and export, and nutrient export were quantified using the InVEST (Integrated valuation of ecosystem services and trade-offs) model. Results indicate that disturbances to mangrove forests in Odisha can emit 2.16 Tg C back into the atmosphere by 2030. In an optimistic scenario, mangroves can sequester 1.55 Tg C from the atmosphere. An increase in mangrove and green cover has reduced sediment and nutrient export by a maximum of 24.9% and 7.6%, respectively. The findings will help in evidence-based decision-making about the socio-environmental systems comprising sensitive mangrove ecosystems.

“…Hal ini sesuai dengan hasil analisis data menunjukkan pertambahan luas tambak akibat konversi hutan mangrove, belukar dan badan air. Beberapa hasil penelitian menunjukkan kecenderungan luas hutan mangrove berkurang akibat dikonversi menjadi tambak untuk budidaya ikan (aqua-culture) (Sandilyan & Kathiresan, 2012;Herbeck et al, 2020;Aslan et al, 2021;Hamilton, 2013).…”

The land use and land cover change phenomenon has become one concern over many regions worldwide, including Indonesia. Land use and land cover change due to human activities triggered alteration terrestrial ecosystems and its services including climate control functions. The study aimed to analyze land use and land cover change in Banyuwangi regency during 1995 – 2019. Four satellite images from acquisition year 1995, 2000, 2014 and 2019 were used to analyze the spatial and temporal changes along with field observations. The classification processes of land use and land cover included determination of training areas, supervised classification, and accuracy assessment. There are 12 land use and land cover based on supervised classification as follow primary forest, secondary forest, plantation forest, mangrove forest, plantation, settlement, cropland, paddy field, shrubs, water, fishpond and barren land. The result showed during observation period of 1995 until 2019 land use and land cover which tends to decrease are secondary forest, mangrove forest, and rice fields. On the other hand, the area of settlements, shrubs and fishponds were increased significantly.

“…The study's conclusions is that the net change in mangrove forests from 2001 to 2019 is 0.01% per year in the studied region. Aslan et al (2021) discovered that 62% of the 96,298 ha of mangrove forests in the Mahakam Delta in Indonesia were deforested during the study period in their study to evaluate the spatiotemporal dynamics of large area mangrove deforestation, aquaculture pond building, and subsequent abandonment of ponds, primarily for building shrimp and fish ponds. Achionye et al (2018) examined the land-use and land-cover transition of the Warri vegetation zone of the NDR over the last four decades using Landsat imageries for 1975, 1987, and 2015 with the aid of RS techniques and GIS.…”

Land use dynamics describes the changes occurring in an area which can be approximated from a land use and land cover map (LULC). This research aims to assess how the mangrove forest in the Niger Delta Region has degraded. Landsat imagery of 1987, 2002, and 2022 were used to create LULC maps from which change detection of the area derived from supervised classification technique, were investigated. The classification accuracy was determined and the result shows that for 1987, 2002, and 2022 the accuracy score are 82.16%, 82.16%, and 83.97%, respectively and the corresponding kappa coefficients for the epochs are 75.63%, 75.63%, and 78.43%. The producer and user accuracy are high for all the classes except grassland and urban areas. The change detection result showed a net loss in mangrove, grassland, and water bodies between 1987 and 2002 with significant gains for urban and woodlands however significant losses were revealed in the mangrove, woodlands, water bodies, and grassland with gains in only the urban settlement between the 2002 and 2022 study period. The result also revealed that the mangrove forest cover has seen a consistent loss in the two study periods. The Niger Delta Region is a key component of the global climate system and our research provides an accurate assessment of the land use dynamics and the mangrove degradation in the region.
