Nutrient enrichment of marine ecosystems is regarded as a pressing global environmental problem. For certain marine species it may be a mixed blessing, resulting in damaging ecosystem events, but contributing to primary productivity. Consequently, the impact of enrichment on fishery profits may...

There is now increasing recognition that the world's marine ecosystems, especially coastal areas and semi-enclosed seas, are suffering from degradation and modification due to human influences. One of the most serious problems is nutrient enrichment, which in the long term harms productivity and...

We analyzed the factors determining mangrove conversion by shrimp farmers in the coastal provinces of Thailand between 1979–1996. The profit-maximizing behavior of a shrimp farmer converting mangrove area under open access conditions is modeled. Aggregate mangrove clearing by all farmers in...

Mangroves are considered ecologically important due to their role as breeding grounds and nursery habitats for off-shore fisheries. However, mangrove deforestation through conversion to shrimp aquaculture threatens this valuable function. This paper develops a "dynamic" production function...

Remittances to developing countries exceed $550 billion annually. Although many poor rural households that depend on these remittances also harvest local common-pool resources, few studies explore this relationship. We develop a dynamic model of a coastal fishing household with remittance...

The following paper analyzes the economic and demographic factors determining the conversion of mangroves in the coastal provinces of Thailand to commercial shrimp farming. Mangrove conversion is therefore determined by the returns to shrimp farmers (i.e. the price of shrimp), the input costs to...
