Abstract

The article develops a dynamic model of habitat-fishery linkage in which the habitat is being converted. The basic model is applied to a case study of the impacts of mangrove deforestation on the artisanal marine demersal and shellfish fisheries in Thailand. The comparative static effects of a change in mangrove area on the long run equilibrium level of effort and fish stocks, as well as on the resulting market harvesting supply of the fishery, are determined. By estimating parameters through pooled time-series and cross-sectional data over the 1983-1996 period for the five coastal zones along the Gulf of Thailand and Andaman Sea, the welfare impacts of mangrove deforestation are estimated. Mangrove conversion is expected to be a function of the returns to shrimp farming and the input costs to farming shrimp, plus exogenous economic factors. The resulting aggregate reduced-form level of mangrove clearing by all farmers in coastal areas is empirically estimated across the five coastal zones in Thailand over 1983-96. The policy implications of the findings are discussed with respect to Thailand and the modelling of habitat-fishery linkages.
