What are economic values of water bodies and wet lands? Suggests measures for revitalizing urban water bodies.

Wetlands around the globe are being modified, reclaimed and overexploited due to high levels of resource consumption, land conversion and/or upstream developments that alter the quality and flow of water that feeds into them. Decision makers often have little understanding of the economic value of wetlands because wetlands are often perceived as having little or no value compared with uses that yield more visible and immediate economic benefits (Schuyt and Brander, 2004). In the United States, 87 million hectares (54%) of original wetlands (Tiner, 1984) have been converted, primarily for agriculture. In Portugal, 70% of the Algarve region has been converted for agriculture and industrial development (Pullan, 1988). In the Philippines, 300,000 hectares (67%) of the country’s mangrove resources were lost between 1920 and 1980 (Zamora, 1984).

 Wetlands are one of the earth‘s most productive ecosystems. They have been described both as “the kidneys of the landscape,” because of the functions they perform in the hydrological and chemical cycles, and _______ _________ ________ _____ _________ _________ __________ _______ ___ _________ _______.
