The long-term economic impacts of the AIDS epidemic on orphans have been major concerns in countries hit by the epidemic. Responding to these concerns, previous studies have investigated the schooling of orphans. Yet, few studies have investigated the impacts of orphan status into adulthood. Therefore, this paper examines the education attainment and land inheritance of former orphans, who have lost at least one parent before reaching 15, by using a survey of 889 households in Kenya in 2004. In the survey, we have asked the ages of household members when they lost their parents, if they have suffered such a loss, and identified former orphans. Among individuals who started schooling before the Free Education Program introduced in 1974, we find about a one... |

Basmati is well renowned as the most aromatic rice over the world. Populated urban markets are prone to accept a premium to Basmati, whom price is the highest for rice on trade and domestic markets. Punjab province represents 90% of overall Basmati rice production in Pakistan since immemorial times. This area forms the genuine alluvial lands appropriate for Basmati cultivation. Due to its price premium, some opportunist behaviors appear such as cropping blending of polished long grain from other varieties. The need of protection is clearly documented, but the registration of a Geographical Indication, will probably increase Basmati market shortages. |

In this paper the incremental values of water are calculated for irrigators in the Fish-Sundays Scheme of South Africa's Eastern Cape province. The socio-political pressure for redistribution of agricultural resources provided the imperative for this study. The model of the Fish-Sundays Scheme reflects a survey of 50 000ha of fodder and citrus production. It explicitly models the water demand on sixteen typical farms, for five irrigation technologies, six crops and four livestock activities. The existing allocation generates an average value of R0.0423/m3/year, which increases to R0.0681/m3/year if farmer-to-farmer trading is allowed given existing infrastructure. Unrestricted trade raises the average value to R0.0719/m3/year. The marginal cost of... |

This paper examines the linkages among agricultural total factor productivity, farm size, and farm household participation in the off-farm labor market for the Southeastern states for the period 1960-1996. We find evidence of a simultaneous relationship between productivity and measures of farm structure. The results support the expected relationships between the endogenous variables, namely that productivity and farm size are positively related, farm size and off-farm work participation are negatively related, and off-farm work and productivity are negatively related. We find positive and significant impacts of government policies (investments in public research, extension, and highways) on productivity growth. |

This paper draws attention to the specific post-civil-war situation in agriculture and the food sector in Bosnia and Herzegovina (B&H). These developments are presented in an association with the overall situation in the country. Due to economic and non-economic reasons, B&H faces a general problem of a lack of international competitiveness. In a current situation, there are rare products to be internationally competitive and the country relies on imports of food and other products. During the post-civil-war emergency and reconstruction stage, the bulk of food and agricultural inputs, were donated or granted by different governments, humanitarian organizations, and donors to mitigate the effects of widespread poverty caused by the war destructions... |

Recent increases in fertilizer, particularly nitrogen, and fuel price have resulted in increased production cost for farmers. In this paper a farm level production model that compare uniform and variable rate fertilizer (NPK) application is developed that permits an analysis of the economic performance of fertilizer management regarding profitability. Results show that farmer's exposure to fertilizer and fuel prices risk have substantial impact both on the expected net returns and production practices for producers both uniform and variable rate technology. |

This paper examines whether sharecroppers and fixed-rent tenants in the rice farms of South Asia are distinguished by their farming skills. The idea that fixed-rent contracts are typically given to relatively skilled tenants dates back to the agricultural (tenancy) ladder hypothesis of Spillman [1919]. The screening models [e.g. Hallagan 1978] that have attempted to formalize this idea assume that landlords do not observe the tenants skill levels. This assumption is restrictive, and has found little support in empirical studies. The principal-agent model proposed in this paper focuses on the differences between time-intensive and skillintensive labor tasks. I show that tenancy contracts are designed to match the provision of these tasks with the owners of... |

This paper adds to the debate on the impact of market reforms versus structural reforms in explaining agricultural output growth in China. A multiple-output stochastic frontier and a technical inefficiency equation are estimated using provincial data on the rural economy from 1986 to 1995. Grain self-sufficiency policies and incomplete market reforms in the 1980s and 1990s led to allocative inefficiency. Agricultural disinvestment shrunk the production frontier and the fragmentation of land holdings reduced technical efficiency. China's rural economic reform is far from being complete. |

In this study, the cost of groundwater extraction, impact of groundwater depletion on farm income, wateruse efficiency, technical efficiency in crop production and costs of groundwater depletion among different categories of farmers have been reported. The study has been conducted in the Chamarajanagar district of the Karnataka state, where groundwater is the major source of irrigation. Data have been collected from over-exploited, semi-critical and safe villages. The study has shown a wide difference between large and small farms in their access to groundwater resource in terms of cost. The functional analysis has revealed that farm income is lower in over-exploited and semi-critical villages compared to safe villages. The mean technical efficiency in... |

In Germany, since several decades the RAUMIS modelling system is applied for policy impact assessments to measure the impact of agriculture on the environment. A disaggregation at the municipality level with more than 9.600 administrative units, instead of currently used 316 counties, would tremendously improve the environmental impact analysis. Two sets of data are used for this purpose. The first are geo-referenced data, that are, however, incomplete with respect its coverage of production activities in agriculture. The second set is the micro census statistic itself, that has a full coverage, but data protection rules (DPR) prohibit its straightforward use. The paper show how this bottleneck can be passed to obtain a reliable modelling data set at... |

As a consequence of the reorientation of the Swiss as well as the European agricultural policy, prices for agricultural products drop and farmers have to reduce their production costs or will lose income. Therefore a lot of farmers have a high incentive to change their production structures. One of the most effective strategies to reduce production costs is going into cooperation and collaboration with other farmers. Therewith farmers can profit from scale effects without changing the property rights. Several case studies as well as results from modeling reveal that farmers have more income with less workload. In reality only 3% of Swiss farmers have gone into a collective farming system. Weaker forms of cooperation like sharing machinery are more common... |
