Human impacts on mangroves have been severe in some places, and include dredging, filling, diking, oil spills, and runoff of human waste and herbicides. 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. In particular, 81% of mangroves are … : Earth Environ. 4.1 The human footprint on global mangrove loss. References … There are many cases relating to the conversion of major mangrove sites as agriculture spots.
