The pastoralism of the Turkana has persisted in the challenging environment of northwestern Kenya for some 200 years. Yet many pastoralists find that they increasingly rely on food relief during droughts and famines. This article contextualises emergency responses to famine among Turkana pastoralists by considering their encounters with colonialism, development, and humanitarian interventions. It uses key informant interviews, participant observation, and content analysis, to analyse the benefits and challenges of a small-scale food relief programme. The article argues that such programmes can weaken the viability of pastoralism, and concludes with considerations for future policy and programming.  相似文献

This article analyses and describes the relationship between the size of operational holding on the one hand and various irrigation and irrigation‐related variables, on the hand, using cross‐section regression analysis of farm‐sizewise/statewise Indian data. The overall conclusion that emerges from the analysis is that irrigation development in India as a whole seems to be such that its propagation and diffusion among agricultural households seems to be somewhat in favour of larger farms. Even though the government predominantly controls the development and distribution of flow‐sources of irrigation, especially of canal irrigation, it does not seem to have produced any significant positive impact on reducing the level of inequity involved in the distribution of irrigation across farm‐size groups.  相似文献

This article examines the determinants of various rates of agricultural subsidies (output, input, exchange rate distortions, and aggregate) using commodity-level data from eight African countries in the 1980s. Econometric results indicate that structural adjustment policies were more effective in reforming exchange rate distortions than in liberalising commodity markets. Output policies are determined within the national context while input subsidies are more responsive to commodity-specific conditions. Further-more, agricultural subsidies were strongly influenced by the degree of urbanisation and by the number of people per unit of arable land in a manner consistent with cheap food policy strategies.  相似文献

African smallholders face few opportunities that can be captured through new technologies alone. Analysis of the institutional context in which they work opens new pathways for innovation. This article synthesises nine studies that attempted such analysis. Using mixed appraisal methods, the studies identify institutional conditions that explain the, often unsatisfactory, outcomes of smallholders, as well as entry points for changing them. Instead of at the farm or community levels, Participatory Innovation System Analysis seeks at higher levels to identify actors, networks and mechanisms that maintain or can change the “pervasive bias against the small farm sector” in SSA.

Défier le « biais omniprésent » à l'encontre des petits cultivateurs africains: identifier les points d'entrée pour les changements institutionnels

Les petits cultivateurs africains ont à leur disposition peu d'opportunités qui puissent être saisies par le seul biais des nouvelles technologies. Une analyse du contexte institutionnel dans lequel ils travaillent ouvre de nouvelles voies pour l'innovation. Cet article synthétise neuf études qui ont tenté une analyse de ce type. À l'aide de méthodes d’évaluation mixtes, les études identifient les conditions institutionnelles qui expliquent les résultats, souvent insatisfaisants, obtenus par les petits cultivateurs, ainsi que les points d'entrée pour les modifier. Au lieu de le faire aux niveaux des exploitations ou des communautés, l'Analyse participative des systèmes d'innovation cherche à identifier à des niveaux supérieurs les acteurs, réseaux et mécanismes qui maintiennent ou peuvent modifier le « biais omniprésent à l'encontre du secteur des petits cultivateurs » en Afrique sub-saharienne.

Cuestionando “el prejuicio persistente” contra los pequeños productores africanos: identificando puntos de abordaje para lograr el cambio institucional

No existen muchas oportunidades de desarrollo dependientes exclusivamente del uso de tecnologías nuevas que puedan ser explotadas por los pequeños productores de África. El análisis del contexto institucional en el que éstos trabajan permite abrir nuevas vías para la innovación. El presente artículo sintetiza nueve estudios que realizaron dicho análisis. A partir del uso de distintos métodos de valoración, dichos estudios identificaron las condiciones institucionales que explican los resultados —a menudo insatisfactorios— obtenidos por los pequeños productores y señalan los puntos de abordaje para mejorar tales resultados. En vez de ser aplicado a nivel de parcela o de comunidad, el Análisis Participativo de Innovación de Sistemas procura identificar a aquellos actores, redes y mecanismos existentes a niveles superiores que pueden mantener o transformar el “perjuicio persistente contra el sector de las pequeñas parcelas” en el África Subsahariana.

Desafiando o “preconceito difundido” contra os pequenos proprietários africanos: identificando portas de entrada para mudança institucional

Os pequenos produtores africanos possuem poucas oportunidades que só podem ser aproveitadas com novas tecnologias. A análise do contexto institucional no qual eles trabalham abre novos caminhos para a inovação. Este artigo sintetiza nove estudos que visaram tal análise. Utilizando métodos de avaliação mistos, os estudos identificam condições institucionais que explicam os resultados, frequentemente insatisfatórios, de pequenos produtores, além de portas de entrada para modificá-los. Em vez dos níveis rurais ou comunitários, a Análise Participativa do Sistema de Inovação busca em níveis mais altos identificar agentes, redes e mecanismos que mantêm ou podem mudar o “preconceito difundido contra o setor dos pequenos produtores rurais” na África Subsaariana.  相似文献

This article uses public documents and first-hand accounts of late 19th and early 20th centuries child life to examine attempts by public policymakers in the United States and New Zealand to change the quality of rural child life in those countries through compulsory schooling and other related measures. These attempts, however, largely failed due to the demands of the farming economy and the unwillingness of public officials to go to extraordinary lengths on behalf of farm children, as opposed to urban children. Rural children's lives would be changed, not by policy, but by technological developments and the vagaries of the farm economy.  相似文献
