Mangroves have always been economically important to man and have provided us with food and all manner of products for thousands of years. Recently, however, many planners and bureaucrats have tended to view mangroves as eyesores and 'waste-land'. As a result, partially in response to 'market forces' and the pressures of economics, modern conservation efforts have tended to increasingly emphasise their economic value to man.
The economic value of anything is the amount of money people are willing to pay for it. Economic values can be divided into two typesdirect and indirect.
Direct value refers to harvestable products for personal use or for sale in local and international markets.
Indirect value refers to services or uses which do not use up the resource. This includes environmental services provided by biological communities not consumed through use (non-consumptive use value), potential uses or services from previously untapped species (option value), and the amount of money people are willing to contribute to ensure the continuing existence of a natural resource (existence value).
The viviparous seedlings of Avicennia and Bruguiera species are also boiled and eaten, presumably in times of famine. Many mangrove species are exploited for their medicinal usage. Some of these may be seen from the species descriptions given in this website.
