摘要：A phenomenal growth of Intensive shrimp faring has been seen in the Chanthaburi province in the East Coast of Thailand since its inception in late 1988. The province got more attention after failure of shrimp farms in the upper Gulf of Thailand. Using Landsat TM data of 1987, status of shrimp farming before the beginning of full scale intensive shrimp farming in Chanthaburi province has been examined and it is found that only 299 hectare of land was under farming during that period of time. ADEOS-AVNIR image of 1997 provides a very clear picture of recent status and it found that 11,277 ha of land is under shrimp farming. Environmental impacts and its costs vary with the locations of the shrimp farms and it is dependent on specific environmental conditions of farm location. Shrimp farms located in the mangrove area, having impacts on nearby farmlands bear maximum environmental cost. Since such kinds of land provide a number of goods and services, therefore, environmental cost is very high. Environmental cost is quite low for those located in the vacant land without having impacts on nearby lands. It is found that from private point of view, economic incentive or excess profit (64,338 Baht/rai/year, 1 US$ = 37 Baht) still exists and this will bound to attract further investment in future. This kind of profit may possibly be the highest among many other farming alternatives. However, on considering the environmental cost, Net Social Profit (21,309Baht/rai/year) of the shrimp farming becomes significantly low
