Adaptation of mangrove ecosystems under the impacts of sea level rise case studies in Red River Delta

Abstract

    Conservation and sustainable development of mangrove ecosystems has been considered as one of the measures and plans to adapt to the consequences of climate change. Itself mangrove ecosystems also suffer from the direct and indirect effects of climate change. Sea level rise due to climate change is one of the factors that impact directly and indirectly to the mangrove ecosystem. With these impact, the mangrove ecosystem can develop and exist in the same position if the sediment accumulation rate (increasing the strata) of the area corresponding to the change of sea level. In addition, these ecosystems can landward and seaward margins transgress seaward if sea level drops to the mangrove surface. (1) Studies in the Red River Delta that sedimentation rate is generally quite high but uneven across the region. Moreover, previous studies also showed that the sedimentation rate areas most impact not only of nature but also of human activities. (2) Results of research on sea level rise (MONRE, 2010) showed that the Red River Delta have a higher sea level rise of from 0.16 to 0.20 cm/year compared to the national average. (3) The fact, it is clear that the entire system of sea dikes in northern coastal areas has been concreted and upgraded. Synthesis and analysis of the three factors can be found that the mangrove ecosystem in the Red Rive Delta is in the face of regression with the impact of sea level rise due to climate change.
