Abstract
Mangrove forests along the Vietnamese coastline provide multiple ecological, environmental, and economic services, including being a habitat for different flora and fauna, shoreline protection from erosion, storms, and waves, and providing several raw materials for industries. The coast of Quang Ngai province in Central Vietnam didn't get much attention from the research community, particularly on the mangrove reforestation programs and coastal environmental changes in the province. In the present study, we investigated the shoreline changes in Quang Ngai Province since the late 1980s, recent mangrove reforestation initiatives, and its progress in the area using medium-resolution Landsat imagery series and Sentinel-2 data. The results were compared with mangrove areas estimated from high-resolution RapidEye and PlanetScope imagery for accuracy analysis. There has been a slight increase in the area occupied by mangroves along the Quang Ngai coast between 2007 and 2022 compared to the area of mangrove patches in the 1980s. An increase in the area of inland mangroves offers various ecosystem services to the regional community, improvement in livelihood, and quality of environment. Our results indicated that the erosion-accretion changes along the coast of Quang Ngai were not unique and that some areas, such as the urbanized northern part, have eroded higher than southern areas except where sediment supply from larger rivers in the province is high. The mangroves planted in Bau Ca Cai wetlands indicated a success and such initiatives can be conducted throughout the south-central coast of Vietnam for long-term coastal protection.
期刊介绍:
Environmental Development provides a future oriented, pro-active, authoritative source of information and learning for researchers, postgraduate students, policymakers, and managers, and bridges the gap between fundamental research and the application in management and policy practices. It stimulates the exchange and coupling of traditional scientific knowledge on the environment, with the experiential knowledge among decision makers and other stakeholders and also connects natural sciences and social and behavioral sciences. Environmental Development includes and promotes scientific work from the non-western world, and also strengthens the collaboration between the developed and developing world. Further it links environmental research to broader issues of economic and social-cultural developments, and is intended to shorten the delays between research and publication, while ensuring thorough peer review. Environmental Development also creates a forum for transnational communication, discussion and global action.
Environmental Development is open to a broad range of disciplines and authors. The journal welcomes, in particular, contributions from a younger generation of researchers, and papers expanding the frontiers of environmental sciences, pointing at new directions and innovative answers.
All submissions to Environmental Development are reviewed using the general criteria of quality, originality, precision, importance of topic and insights, clarity of exposition, which are in keeping with the journal''s aims and scope.
