This article investigates off-farm work decisions by smallholder farm households. Using data on 1,101 households from Burkina Faso, it demonstrates that in addition to the usual household socio-demographic characteristics, remittances, access to information and beneficiary of specific training affect off-farm work decisions, as well as rainfall factors and idiosyncratic health shocks. Community characteristics such as accessibility and number of inhabitants are also key factors. While suggesting that off-farm work is less likely to be undertaken for accumulation purposes, these results have important policy implications. In particular, policy measures should consider each segment as a separate entity.  相似文献

全球化视野下的中国农民问题   总被引:1,自引:0,他引:1  
中国的三农问题引起了越来越多的关注,中央政府希望通过农业补贴、减少税费等措施提高农民收入。但是与20世纪80年代中国农村不同,中国农民已经处于全球化的影响之下,这种影响已在农民就业、农业生产组织和农业生产三个方面充分展示。因此,我们必须站在全球的角度来看待中国的农民问题。  相似文献

More than a decade after NAFTA (North American Free Trade Agreement) entered into force, the environmental effects of agricultural trade liberalization in Mexico are still controversial, emerging, and not fully understood. This paper contributes to the literature that aims to explore trends in input use in the agricultural sector in Mexico during the post-NAFTA period among both commercial/industrial and traditional/rainfed farmers, and examines the influence of the national and multilateral institutional framework on these outcomes. We decompose the post-NAFTA agricultural production data into scale, technique and composition effects to estimate the impact that trade liberalization has had on the use of fertilizer and land use, two key agricultural inputs for which reliable aggregate data is available. We conclude that among commercial farmers patterns of crop type specialization and significant technological improvements have led to some declines in fertilizer use but they have been offset by growth in fertilizer use associated with growing agricultural output. Among traditional farmers increased output and specialization in land-intensive grain crops are contributing to an increase in land under cultivation and technological improvements show the potential, but not yet not the strength, to counteract these effects. We analyse the environmental institutional framework and rural development plans, observing that institutional weaknesses have, in several instances, reduced the environmental benefit of technique and composition effects. We conclude with recommendations about how the Mexican agricultural sector might reap the environmental benefits of international agricultural trade.  相似文献

African indigenous vegetables (AIVs) have potential to sustainably address malnutrition, a growing problem in sub-Saharan Africa. Their consumption is however, limited by poor perceptions and lack of awareness of nutritional benefits. There is limited evidence of the effectiveness of community-focused information dissemination approaches in influencing participants’ perceptions and uptake of innovations in AIVs to address malnutrition. This article aims to fill this knowledge gap, using a case study focusing on pastoral communities in Monduli district in northern Tanzania. Target communities participated in a community-based nutritional outreach facilitated by the Good Seed Initiative (GSI), held at Monduli district hospital in September 2014. The results provide evidence of the achievements of the GSI intervention, and the effectiveness of alternative information dissemination approaches.  相似文献

This article examines the structure of the Malian fertiliser value chain and its performance in the context of the national subsidy programme, drawing on a review of the literature, farm household survey, and interviews with fertiliser suppliers. It finds that participants in the subsidy programme use more fertiliser and have significantly higher yields. The number of wholesalers and retailers has risen, but procurement remains concentrated. Poor fertiliser quality is a recurrent problem. The high cost of the programme raises questions regarding its sustainability. Mixed performance reflects the need for better monitoring and evaluation, and transparency in the programme.  相似文献

Great changes are underway in how climate and agricultural risks are managed in Vietnam. Uncertainties are emerging regarding the role of the state in managing these risks and what this implies for assumptions regarding hoped-for climate change transformations. Local government control is waning in relation to the expanding roles of the private sector and the growing autonomy of farmers themselves. This article presents cases that illustrate the ways that farmers, private investors, and local authorities are responding to climate risk within roles relating to the other risks involving markets, food security, and pressures on common property resources.  相似文献

This article investigates how the introduction of new crops influences intra-household decision-making among the Ovambo in northern Namibia where women are responsible for crop farming, while men are engaged in livestock farming. It examines gender relations that underlie daily activities. The findings of the study show that women try new crops on their own or with the help of their children and do not negotiate with their husband, mothers, or brothers over household resources such as land, labour, and the cash of other family members. Women avoid conflicts with family members, but may have an increased perception of contribution to the household if they succeed in introducing new crops.  相似文献

Participatory governance offers the potential to deliver responsive and accountable services. This article tests this expectation by looking at how members of participatory extension platforms in Malawi understand the meaning of “demand-driven” services, and allocate responsibility and influence in service provision. Results show that most respondents agree on bottom-up extension services that respond to expressed farmers’ needs (86% of respondents), and assign responsibility and influence widely across state and non-state actors. While these findings suggest that these participatory mechanisms can promote responsiveness to farmers’ needs and accountability, they also point toward different governance challenges in extension services.  相似文献
