RT null T1 Global Status of Mangrove Ecosystems: Commission on Ecology Papers Number 3 A1 International Union for Conservation of Nature, A2 Saenger, Peter A2 Hegerl, Eddie A2 Davie, John K1 mangrove swamp K1 aquaculture K1 agriculture K1 solid waste management YR 1983 FD 1983 LK https://wedocs.unep.org/handle/20.500.11822/29665 UL https://wedocs.unep.org/handle/20.500.11822/29665 NO This report examines the ecological characteristics, distribution, uses, and management of mangrove ecosystems in tropical and subtropical coastal regions. It compiles available data on global mangrove extent, species composition, and associated biological communities, drawing on published studies, questionnaires, and mapping techniques to describe their geographic distribution and ecological diversity. The document explains key ecological processes such as nutrient cycling, sediment dynamics, and the export of organic matter that supports estuarine food webs and fisheries. It also analyses major causes of mangrove degradation, including freshwater diversion, mining, coastal development, and land conversion. The report further reviews governance arrangements, international cooperation needs, and management approaches intended to support sustainable use and long-term conservation of mangrove resources.
