Abstract : The natural importance of mangroves and the economical uses of mangroves needs to be analyzed. The natural and economic value of mangroves needs to be balanced so their is no misunderstanding of the adequate use of this valuable resource. Their should be a balance between the natural and economic uses so the value of the mangrove in natural and economical terms can be mantained over time. However, the natural importance is forgotten when their are economical interests involved. The mangroves in natural & economical terms is important because it serves as breeding and nursery grounds to many marine organisms, they are buffers between land and sea(prevent soil erosion), reproductive strategies that make them colonize their environment,biodiversity anomalies dependent on longitude and other factors, main source of tannins, woods, food sorce, medicinal use,shrimp industries, etc. The mangroves worldwide are reduced due to their use for deveolpment of houses, megahotels, industries & other activities that are dependent on the coastal zone. By the other hand, the mangroves are been degraded(I will bring examples). It's impor- tant to understand the role of mangroves on the protection of other coastal habitats and the consequences of lossing mangroves in those marine ecosystems.
I. Magrove definition. Make a contrast between the natural and "economic" definition.
II. Mangrove Natural importance (Environmental factors that determine mangrove zonation,Reproductive strategies, Biodiversity of species : Mangroves Origin and biodiversity anomalies and the mangrove importance along the coastline)
III. The economical values or human uses given to the mangroves
IV. Some implications of mangrove forest loss. Why is important to mantain mangroves along the coastline. If their is a loss of mangrove natural resource, will it affect adjacent ecosystems that interact with it.
V. Political and Sociocultural actions that affect the economic and natural importance of mangroves.
