L'article propose d'utiliser le concept de sécurisation alimentaire pour étudier les actions et processus qui améliorent une situation alimentaire, plutôt que celui de sécurité alimentaire qui se réfère avant tout à la satisfaction de besoins alimentaires. Dans une première partie, ces deux concepts sont précisés et discutés. La sécurité alimentaire est caractérisée selon plusieurs dimensions : disponibilités, conditions d'accès, qualités des aliments, stabilité, mais aussi objectifs sociaux et politiques.
Esta tesis constituye un insumo construido de manera participativa con las comunidades agrarias y rurales de Camino Verde, El Triunfo, Nueva Gomera, Nuevo Monte Cristo y San Rafael, con el propósito de analizar en conjunto la situación actual y expectativa de desarrollo a futuro de las familias campesinas.
Este programa busca mejorar la efectividad de los procesos de desarrollo en los territorios rurales, para lo cual fomenta la creación de habilidades y actitudes que les permitan a sus habitantes actuar colectivamente en torno al logro de objetivos comunes. Se parte de la premisa de que todos los seres humanos tienen la capacidad de impulsar cambios y adquirir nuevas habilidades, pero esa capacidad debe ser “estimulada y fortalecida”
La herramienta sobre formulación, monitoreo y evaluación de proyectos se ha diseñado con el propósito de que los participantes puedan identificar oportunidades para el desarrollo de un proyecto y le den seguimiento a este tipo de iniciativas. Se muestra que los proyectos tienen un ciclo de vida, surgen alrededor de la identificación de un problema que se desea solucionar, pasan por la ejecución y evaluación y terminan probablemente con la generación del diseño de otro proyecto.
Con el objetivo de generar insumos para las iniciativas TIC de las instituciones públicas para la agricultura y rescatar las experiencias y lecciones aprendidas de los países de America Latina y el Caribe que llevan la vanguardia en este tema, a mediados de 2010 el Centro de Análisis para la Agricultura (CAESPA) del IICA inició un proceso de identificación y análisis de los principales factores que retrasan o limitan el impacto de las TIC en esas instituciones.
This article investigates determinants and impacts of cooperative organization, using the example of smallholder banana farmers in Kenya. Farmer groups are inclusive of the poor, although wealthier households are more likely to join. Employing propensity score matching, we find positive income effects for active group members. Yet price advantages of collective marketing are small, and high-value market potentials have not yet been tapped. Beyond prices, farmer groups function as important catalysts for innovation adoption through promoting efficient information flows.
Natural resource management practices, such as the System of Rice Intensification (SRI), have been proposed to tackle agricultural challenges such as decreasing productivity growth and environmental degradation. Yet, the benefits of system technologies for farmers are often debated. Impacts seem to be context-specific, which is especially relevant in the small farm sector with its large degree of agroecological and socioeconomic heterogeneity. This was not always considered in previous research.
Since the early 1990s, liberalization of the seed market in Tanzania has attracted several foreign companies that now market maize hybrids in the country. In this article, we analyze the impacts of proprietary hybrids on maize yields, production, and household living standards. We build on a recent survey of smallholder maize farmers in two zones of Tanzania. Hybrid adoption rates are 48% and 13% in the North and East, respectively. Average net yield gains of hybrids are 50-60%, and there are also significant profit effects.
Most micro-level studies on the impact of agricultural technologies build on cross-section data, which can lead to unreliable impact estimates. Here, we use panel data covering two time periods to estimate the impact of tissue culture (TC) banana technology in the Kenyan small farm sector. TC banana is an interesting case, because previous impact studies showed mixed results. We combine propensity score matching with a difference-in-difference estimator to control for selection bias and account for temporal impact variability.
A group of researchers and industry writers have constructed a narrative of technological triumph for Bt cotton in India, based on an empirical record of superior performance compared to conventional seed. Counterclaims of Bt cotton failure are attributed to mutually reinforcing interactions among non-governmental organisations which avoid rigorous comparisons. However, researchers and the biotechnology industry are also engaged in a similar authentication loop for generating, validating, and publicising such facts.
