This article examines how farmers use mobile phones to obtain information about rice varieties in eastern India and investigates if this contributes to rice varietal replacement. The findings show that farmers located farther away from the market were more likely to pay for the calls. Moreover, about 26% of the farmers who had to pay to receive calls purchased seeds of at least one rice variety that they had never planted before, while less than 16% of farmers who received no calls did so. Regression results confirmed that paying charges to receive rice varietal information is associated with varietal replacement.  相似文献

Understanding and accounting for the heterogeneity of small farmers is critical for informing development pathways to improve the performance of smallholder irrigation. Using multivariate analysis, this study sought to develop farmer typologies in and around irrigation schemes and used these to inform strategies for on-farm entrepreneurship development. The research uniquely integrates psychological capital in defining farmer typologies, to capture individual features of each farmer, otherwise missed by the generic sustainable livelihoods framework literature. The study affirms the need to focus on psychological capital and concludes that heterogeneity among small-scale irrigators should be accounted for in future agricultural and rural development programmes.  相似文献

与其他学者观点不同,在马克思看来农业劳动价值萎缩是资本诞生后工农业和城乡分离必然带来的结果.立足马克思的劳动价值理论分析,农业劳动价值萎缩必然带来的是农民经济收入减少以及由此造成的收入不可预期,而这与影响农业体面劳动的关键因素是一致的,据此农业劳动价值萎缩和农业体面劳动困境之间存在着深刻的关联逻辑.当代中国农业劳动价值...  相似文献

农业生产力布局是降低农业生产成本、提高农业生产效率和满足人民日益增长的关于农产品美好生活需要的重要因素。基于第一产业和农业的地理分布格局演变历程,本文提出目前我国农业生产力布局存在粮食总量保持稳定,但是未来存在安全隐患;农产品生产聚集程度总体较高,但是仍有进一步提高空间;农产品尤其是粮食生产成本较高,需要进一步降低生产成本;农产品市场价格较高且有上涨趋势,需要稳定其价格等四个特征。指出未来农业生产力布局调整应该遵循总量安全原则、比较优势原则、规模经济原则、产业链一体化发展原则,并提出相应的政策建议。  相似文献

Separating the commercialisation of agriculture from other programmes to improve access to formal credit for smallholder farmers is a source of dramatic failures of most programmes. Despite the popularity of value chain financing, livestock agriculture remains marginalised. This paper analyses the MAFISA-NERPO Livestock Credit Scheme, a scheme which provides value chain financial products in order to improve the cash incomes of smallholder farmers in South Africa. Evidence shows that more than 80% of participating farmers receive average annual incomes of US$30,000. This implies that this scheme has addressed those factors hindering effectiveness and efficiency of smallholder credit institutions, using value chain finance.  相似文献

This article examines the potential of beekeeping, as an appropriate livelihood strategy for smallholder farm households using the sustainable livelihoods framework. A study undertaken over a six-year period (2004–9) with over 300 small-scale farmers in Kenya's Rift Valley Province found that despite excellent revenue earning potential, honey yields and returns remain comparatively low. Compared to maize, the staple crop of most Kenyan farmers, it was found that a typical ten-hive enterprise generated earnings equivalent to 0.86ha of maize. The article emphasises the need to build human capital for beekeeping rather than just promoting modern beehives.

L'amélioration des moyens d'existence pour les petits apiculteurs au Kenya

Cet article examine le potentiel de l'apiculture comme une stratégie adaptée à l'amélioration des sources de revenu pour les ménages de petits agriculteurs en se servant du cadre moyens d'existence renouvelable. Une étude d'une durée de six ans (2004-09) entrepris parmi plus de 300 petits agriculteurs dans le Rift Valley Province du Kenya a trouvé que, malgré le potentiel excellent pour faire des bénéfices, la récolte du miel et les revenus restent relativement faibles. Une comparaison avec le maïs, la culture de base de la plupart de fermiers kényans, a trouvé qu'une entreprise typique de dix ruches génère un revenu qui est l'équivalent de celui produit par 0.86ha de maïs. L'article souligne l'importance de développer le capital humain pour l'apiculture plutôt que de se limiter à la promotion de ruches modernes.

Mejoras en los medios de vida y los pequeños apicultores de Kenia: el potencial no realizado

El presente artículo analiza el potencial que tiene la apicultura como estrategia de sustento para los pequeños productores que utilizan el marco de medios de vida sustentables. Durante seis años, de 2004 a 2009, se llevó a cabo un estudio entre 300 pequeños productores de la provincia del Valle Rift en Kenia, el cual evidenció que, a pesar de su excelente potencial para generar ingresos, los rendimientos de miel y las ganancias se mantienen relativamente bajos. Asimismo, se halló que, en comparación con el maíz, cultivo básico de la mayoría de los campesinos kenianos, el conjunto típico de 10 colmenas generó ganancias equivalentes a 0.86 ha de maíz. El artículo concluye afirmando que, además de promover la apicultura moderna, es necesario construir el capital humano para la apicultura.

Melhoria dos meios de subsistência e pequenos produtores de abelhas no Quênia: o potencial não-percebido

Esse artigo examina o potencial da apicultura como estratégia adequada para meios de subsistência de famílias de pequenos produtores rurais utilizando a estrutura de meios de subsistência sustentáveis. Um estudo realizado durante um período de seis anos (2004–9) com mais de 300 pequenos produtores rurais da Província de Rift Valley, no Quênia, constatou que apesar do excelente potencial para gerar renda, a produtividade e rendimento da apicultura permanecem comparativamente baixos. Em comparação com o milho, plantação básica da maioria dos produtores rurais quenianos, constatou-se que um empreendimento típico com dez colméias gerou ganhos equivalentes a 0.86ha de milho. O artigo enfatiza a necessidade de se desenvolver capital humano para apicultura em vez de apenas promover instalações modernas para a produção de abelhas.  相似文献

This study assessed the effect of participation in off-farm work on the food security status of farming households in the Northern Region of Ghana. Primary data were solicited from 324 farming households in the Tamale metropolis and Tolon district using semi-structured questionnaires. The treatment effects of both income and food security status were estimated using propensity score matching and double-robust methods. The empirical results suggest that participation in off-farm activities increased household daily calorie consumption. These results have implications for the development of off-farm ventures for the benefit of the farming households.  相似文献

Aquaculture of giant clams was developed in the Pacific region in the 1970s and 1980s, linked to community farming and efforts to develop commercial opportunities, particularly high-value exports. Giant clam industries did not develop as expected, but nonetheless many countries still have giant clam aquaculture programmes. Investigations in three countries indicate that giant clams hold other values, notably cultural value, socio-ecological value, value to tourism, and value through building social capital, and these may explain the continuation of the aquaculture programmes. Understanding and adequately assessing local values is a challenge for development investors, who may be missing important impacts from their projects.  相似文献

Rural Kenyan households have different aspirations and income portfolio strategies, including agricultural intensification and income diversification. This article reports on a study that interviewed 624 households to explore rural aspirations and derive lessons for agricultural technology development and transfer. Though few households specialised in farming, many households self-identified as farmers and aspired to increase their agricultural income. Despite the prevalence of agricultural aspirations, few aspired for their children to have a future in farming. Combining aspirations with potential to invest, the article provides suggestions for targeting agricultural interventions. We need to start listening better to those people we call “farmers” to develop and offer innovations that meet their realities.  相似文献

This study assessed farmers’ perceptions of milk-collecting centres (MCCs) in the central and north-eastern regions of Thailand. MCCs can be divided into two groups, dairy cooperatives and private organisations. There were similar perceptions about the role of MCCs among the farmers regarding the basic needs of dairy farmers, but with a stronger focus of economic issues for private organisation members, while dairy cooperative members views were more from the perspective of ownership. The farmers were somewhat satisfied with their MCCs’ performance, except that private organisation farmers were less satisfied with credit services. Policy recommendations are presented.  相似文献
