| In recent years, the growth and intensification of shrimp aquaculture in Asia has been explosive. Asia reportedly produces nearly eighty per cent of the world's total farmed shrimp output. With strong demand and high world prices, along with declining wild shrimp stock, shrimp aquaculture in Asia, particularly in coastal regions, is becoming an increasingly important source of income and employment. In Vietnam, shrimp aquaculture is now one of the most important aquaculture practices in terms of area, production, employment and foreign exchange generation. In the coastal regions of the Mekong Delta, where most of the shrimp aquaculture is practised, saline intrusion in the dry season often limits rice production to just one wet season crop per year.

| This paper explores the economics of land degradation in the rice-shrimp system in the Mekong Delta of Vietnam. A bioeconomic NPV model was developed to evaluate and compare the long-term benefits of alternative production choices and farm technologies. There is an alternative rice-shrimp technology emerging in Vietnam that does not have the same land degrading impacts as the 'traditional' system, however the high capital outlay and risk associated with such technology presents its own problems. In the paper the economic incentives for adoption of the non-land degrading rice-shrimp technology are explored. Conclusions are drawn with regard to the opportunity cost of land degradation and technological change. Some conclusions are also provided on the policy... |
