Different Kinds of Mangrove Forests Provide Different Goods and Services (Ewel et al, 1998)

Intact mangrove ecosystems have remarkable climate change mitigation and adaptation capacities. As mentioned in this study, changes in methodologies and definitions over time make it difficult to compare results from different assessments. Mangrove ecosystems are of great importance to the people of Langalanga lagoon. The mollusc is composed mainly of the Gastropoda and further dominated by two families, namely the Potamidae and Ellobiidae. This mangrove ecosystem is affected by numerous cyc- lonic storms [16].

mangrove ecosystem pdf

A mangrove is a shrub or small tree that grows in coastal saline or brackish water. The term is also used for tropical coastal vegetation consisting of such species. Mangroves are salt-tolerant trees, also called halophytes , and are adapted to life in harsh coastal conditions. They contain a complex salt filtration system and complex root system to cope with salt water immersion and wave action. They are adapted to the low oxygen conditions of waterlogged mud. The mangrove biome , or mangal, is a distinct saline woodland or shrubland habitat characterized by depositional coastal environments, where fine sediments often with high organic content collect in areas protected from high-energy wave action. The term " mangrove " comes to English from Spanish perhaps by way of Portuguese , and is likely to originate from Guarani.

A recent literature review of the Blue Forest valuation research identified mangroves as the most frequently analyzed of these ecosystems, yet the literature demonstrates several deficits in terms of geographic location of studies, methods used to value the services, and most notably, a lack of valuation for cultural services. To better understand this, we analyzed the studies dealing specifically with mangroves from the original literature review to quantify what has been valued, where, by which methods, and the variation in the published values. We then use this information to synthesize our current level of knowledge on the type and value of services provided by mangroves, discuss data gaps, and address specifically the collection of data relevant to cultural ecosystem services CES. Our results shed light on two principle issues affecting the mangrove valuation literature: overuse of benefit transfer in valuing mangrove ecosystem services and a lack of attention paid to the CES that mangroves provide. The mangrove valuation literature is not yet robust, lacking estimates of many ecosystem services, including CES, such as spiritual and aesthetic value. Most published studies focus on a small selection of ecosystem services based on the availability of benefit transfer values and the ability to easily measure values with market prices.

The study of five mangrove forests was undertaken during the summer of on the north coast of Haiti. Interviews with villagers indicated that all the assessed mangroves areintensively harvested for charcoal and fuel wood. This extraction seems tobe the main human disturbance, resulting in changes in forest structure,although heavy fishing and conversion to residential sites constitutedisturbances in some mangroves. The situation is critical but probably notirreversible. However, the socio-economic and environmental conditionsprevailing in the country and the lack of basic information on Haitianmangroves are major obstacles to their preservation.
