However, equally important and at risk are seagrass ecosystems. The intensity of storms in a particular coastal zone is likely to be influenced by mangrove position in relation to storm track, storm characteristics (e.g., wind velocity, storm intensity radius of maximum wind) and degree of exposure (Krauss et al. 2. Like other plants mangroves convert sunlight energy into organic matter through the process of photosynthesis. This article presents an introduction to threats to the coastal zone that result from human activities and pressures. Mangrove ecosystems also play a significant role in providing foods and habitats for diverse ocean and terrestrial organisms (Bayen, 2012) and in transporting carbon and nutrients to the neighbouring coastal zone or ocean (Dittmar et al., 2006).
