This paper sets out to determine the impact of Integrated Agricultural Research for Development in three selected countries of Southern Africa. Agricultural productivity in Southern Africa faces several challenges, of which poor soil fertility strikes out as the priority problem inhibiting increased productivity in farmers’ fields. While several soil fertility management technologies are being promoted in the region, their uptake by smallholder farmers remains very low.
The development of effective agricultural monitoring networks is essential to track, anticipate and manage changes in the social, economic and environmental aspects of agriculture. The authors welcome the perspective of Lindenmayer and Likens (J. Environ. Monit., 2011, 13, 1559) as published in the Journal of Environmental Monitoring on their earlier paper, “Monitoring the World's Agriculture” (Sachs et al., Nature, 2010, 466, 558–560).
Les conséquences sur les territoires des changements climatiques d’origine anthropique sont variables dans leurs expressions comme dans leurs effets, et les territoires sont inégaux face à ces variations climatiques en termes d’exposition aux effets (fonction de facteurs physiques, sociaux, économiques, culturels, politiques, etc.) comme en termes de capacité de réponse (capacité d’appréhension, d’anticipation, de réparation, etc.).
La sécheresse qui sévit dans le Sahel depuis les années 1970 a fortement réduit les productions dans les principaux secteurs d’activités que sont la pêche, l’élevage et l’agriculture. Dans le Delta Intérieur du Niger au Mali (DIN), la pêche dont le développement est intimement lié aux fluctuations inter-saisonnières et interannuelles de la crue du fleuve Niger, est en crise. Les prises ont diminué de moitié, beaucoup de pêcheurs sont partis, certains ont adopté des pratiques non durables et les règles sociales subissent d’importantes modifications.
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.
