| The complexity of modelling risk in farming systems is explained and the artistic nature of the task noted. A brief outline is presented of an appropriate conceptual framework, drawing attention to the merits of stochastic efficiency criteria for analysis of systems when risk preferences of individual farmers are unavailable. A distinction is drawn between planning problems with and without embedded risk. The merits of 'utility efficient' (UE) programming are explained. Extensions of programming models, including UE formulations, to embedded risk using discrete stochastic programming are reviewed. The paper concludes with a discussion of the importance of correctly understanding the way risk impacts upon the target farming system, and then of formulating a... |

| Upland areas in Vietnam account for two-thirds of its natural area and one-third of its population. These uplands are characterized by heterogeneous and fragile ecosystems, a high incidence of poverty, severe deforestation and soil degradation. Rice is an important staple which is grown in the upland fields using shifting cultivation and in intensive lowland fields. The predominantly subsistence-oriented agricultural production system of these upland areas is undergoing intensification due to rapidly increasing population pressure. Changes in government policies regarding uplands and improvements in access to markets have led to the evolution of market-oriented production systems in some areas. In addition, rapid improvement in the productivity of... |

| Annual time series data for the period 1950-51 through 1975-76 are used to estimate the price elasticity of aggregate Australian agricultural supply using two methods. The short-run elasticity is estimated to be highly inelastic but it has been increasing through time. The preferred estimate of the long-run elasticity is in the relatively inelastic range and it has also been increasing through time. Some implications of these results for intersectoral resource flows and compensatory assistance, the cost-price squeeze, the effects of the mineral boom and monetary policy are discussed. |

| The livelihood systems of farm households in coastal Orissa have been analysed based on a sample of 193 farmers. It is found that the incomes of these households were quite diversified. As against the general impression that crop income dominates household income, it is observed that the non-farm income has emerged important in the coastal Orissa. Rice, which has been traditionally the main source of income in this area, has slipped to the third position, next to remittances and income from non-farm activities. The income from non-farm works and rice has accounted for 71 per cent and 20 per cent of the total income, respectively. The non-farm sources have contributed more than 90 per cent towards income inequality. The source-wise income share has also... |

| Drought is a major constraint affecting rice production especially in rainfed areas of Asia. Despite its importance in rice growing areas, the magnitude of economic losses arising from drought, its impact on farm households and farmers' drought coping mechanisms are poorly understood. This paper provides insights into these aspects of drought based on a cross-country comparative analysis of rainfed rice growing areas in China, India and Thailand. The economic cost of drought is found to be substantially higher in eastern India than in the other two countries. Higher probability and greater spatial covariance of drought and less diversified farming systems with rice accounting for a large r share of household income are likely to be the main reasons for... |

| Abiotic stresses observed in the village Kaudikol , district Cuttack, Orissa have been recorded for 8 years and analysed. Survey data collected for four years (1996-97 to 1999-2000) from the farmers of this village have been analysed to find out their livelihood system, importance of rice in this system and the coping mechanisms followed by them in case of loss to the kharif rice crop. The abiotic stresses have been found to cause flood / submergence to different degrees in 5 years, drought in 3 years and cyclone in one year out of the total 8 years, causing production losses to rice. The maximum losses to rice crop have been observed during 1999 kharif season due to cyclone. It has been found that rice is the major crop during the kharif season, covering... |

| This article examines the economics of groundwater irrigation and shallow tubewell (STW) ownership decision making, using farm-level data collected from 324 households in Nepal. STW irrigation generated a significant positive effect on rice yield and farmers’ incomes. Based on a probit model, the farm size, land fragmentation, access to electricity, and access to credit were found to significantly influence farmers’ decisions to own STWs. Although the water market benefited poor farmers, it is too small and monopolistic. Policy reforms needed to make groundwater accessible to the poor majority include effective credit programs, investments in rural electrification, and public sector support for promoting suitable pumping technologies |
