First-time data from over 50 bays and bay segments show stresses largely due to the predicted impacts of climate change and population growth in our region. First, rapid population growth is likely to reduce per capita income growth and well-being, which tends to increase poverty. Aquaculture, the world’s fastest growing food production activity, with an annual growth rate of about 10 percent in the 1990s, can lead to the destruction of mangroves and may lead to irreversible damage to both estuarine and offshore fisheries by introducing biological, chemical, and organic pollutants (such as antibiotics and pesticides) and by modifying habitats. 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. This decline has led to a negative chain of effects in other ecosystems that are dependent on mangrove forest for survival. Influence of mangrove biodiversity on accumulation of carbon and resilience to sea-level rise: A comparative assessment among disturbed, restored, and intact mangrove systems (June 2014 – December 2016).. Globally, mangrove areas are declining rapidly as they are cleared for coastal development and aquaculture and logged for timber and fuel … Responsible for total loss of mangrove habitat in some locations, urban development includes the construction of buildings and canal systems as well as the consumption of water by a growing human population.
