| This second phase of the study is expected to produce actual and accurate information concerning socio-economic information and measures to cope with the El Nino effects at the farm level. Evidence of abnormal weather was apparent in Thailand in 2001 when the rain was less than the previous years' and the high temperatures were from January to March 2002. However, the rain came early in May 2002. Thus, the period of 2001 is suitable to represent an abnormal year for the study of the second phase of the project. The objectives of the second phase are to analyze and evaluate drought impacts at farm-household level, farmer's responses and government measures to overcome the problems. The research was conducted in two different provinces, namely Lop Buri in... |

| Shrimp production in Thailand has historically been undertaken in the saline and brackish waters of coastal mangroves. In recent years rising demand and prices for shrimp and falling productivity of mangrove areas have motivated an expansion of shrimp production into the fresh-water margins of river estuaries that were previously used for rice cultivation. Generalised additive models, which offer a comprehensive approach to regression analysis, are mainly used for empirical analysis, and model development and specification for rice and shrimp production in this study. This paper presents a brief introduction to generalised additive models, discusses how they are applied to develop cost functions to satisfy the restriction of production theory, and... |

| Shrimp farming in Thailand has had disastrous effects on the environment in the past, which has prompted a government ban on shrimp production in inland areas. However, a new low-salinity shrimp farming system has developed that seems to have fewer disease and environmental problems than previous systems but competes with rice production for land and water resources. The present study found that shrimp farming exhibits increasing returns to scale and is much more profitable than rice farming, which offers opportunities for rice farmers to improve their incomes through diversification. No evidence was found for external environmental effects of shrimp production on rice production or vice versa. A total ban on shrimp production in rice farming areas... |

| This study focused on the impacts on vulnerable areas in five provinces and five regions in Thailand. The findings indicated that events caused by El Nino induced weather changes had some impacts on the stabilization of upland agriculture in those vulnerable areas. Broadly speaking, severe drought and a long period of water shortages were experienced by some of the vulnerable areas in Northeast and Central Thailand. Some areas experienced a decrease of corn yield while others experienced complete failure of field corn, sorghum, sugarcane, peanut and mungbean. The impacts of El Nino on the social and economic conditions of Thailand's vulnerable areas were an occurrence of labour mobilization, and weaknesses in purchasing power and loan repayment abilities... |
