Description Vembanad Lake, a wetland of international importance, famous for waterfowl habitat was designated a
Ramsar site, for conservation and sustainable utilisation of the ecosystem. Millennium ecosystem assessment
(2005) emphasises that the various services provided by the ecosystem benefitting human population needs to be
identified and evaluated for judicious utilisation of the resources. Villorita cyprinoides is a major species
contributing to the molluscan fishery of Vembanad lake. The study involving Villorita sp. was taken up with the
objectives of development of a conceptual framework encompassing the different ecosystem services provided by
the clam resources, estimation of the values of selected ecosystem services using appropriate proxies and
analysis of the trade-offs between anthropogenic activities like dredging vis-a-vis clam resources utilizations
following the principles of MEA (2005). The study identified that the clam fisheries in the lake is most
acknowledged for its provisioning ecosystem services. Apart from the regulating services such as water quality
maintenance and carbon sequestration, the cultural and the linking services provided by clam fisheries to
human are also identified. In spite of the identification of the various services, the non-realisation of the value of
the services provided by clam fisheries has prompted the destruction of the resource knowingly or unknowingly
by our activities. One of the anthropogenic activities affecting the clam fisheries is the dredging of sub fossil
deposits of clamshell or white clams which are good sources of calcium carbonate for cement manufacturers.
Identifying the lacunae of non-realisation of the services of clam resources, the paper has judiciously attempted
not only to evaluate the services of the ecosystem service provider but also to externalize the internalities in the
ecosystem services evaluation process by considering the various social costs and benefits associated with the
resource.
