Literature is scanty on how public agricultural investments can help reducing the impact of future challenges such as climate change and population pressure on national economies. The objective of this study is to assess the medium and long-term effects of alternative agricultural research and development investment scenarios on male and female employment in 14 African countries. The authors first estimate the effects of agricultural investment scenarios on the overall GDP growth of a given country using partial and general equilibrium models.
Transforming a centrally planned system of agricultural production to one where individual farmers are accorded choice in crop mix and land use management practices is much more than a structural change. Embedded within this process is a fundamental shift in how knowledge is generated, disseminated and adopted. Upon dissolution of the Soviet Union, one immediate priority was the privatization of state farms and thereby relaxation of policies for collective production.
The objective of this research study was to assess the sources of information on two improved agricultural and livestock technologies (barley variety and feed blocks) as well as the efficacy of numerous agricultural technology diffusion means introduced in the livestock–barley system in semi-arid Tunisia. The research used primary data collected from 671 smallholder farmers.
Face à la dégradation des ressources naturelles liée à la surexploitation, à la croissance démographique et au changement climatique, les services nationaux de vulgarisation en Tunisie nécessitent une révision de leurs priorités et une réforme de leurs modes de prestation de services.
Une évaluation approfondie du système de vulgarisation agricole tunisien montre que des paquets technologiques améliorés destinés au système de production agricole mixte élevage-orge en Tunisie semi-aride permettent d’économiser jusqu’à 40 % des coûts d’alimentation du bétail, mais ne sont pas largement adoptés. Les faibles taux d’adoption sont typiques pour de nombreuses technologies approuvées dans les pays en voie de développement.
The objective of this paper is to analyse the olive oil value chain (OVC) in the Governorate of Medenine (south-east of Tunisia) and the relationships between its main operators for an effective involvement and better performance and resilience of olive sector. Based on semi structured interviews and participatory multi-stakeholders’ workshops, OVC has been analysed and described. MACTOR approach has been applied to establish linkages among chain operators and activities in a partnership approach.
Este estudio analizó la evolución de una red de innovación entre productores de hule natural durante tres periodos de observación (dos olas o tres años), y evaluó cómo los productores reaccionan a diferentes innovaciones en un momento dado. Las prácticas de innovación fueron agrupadas en tres actividades: control de plagas y enfermedades, establecimiento y manejo de plantaciones, y manejo de cosecha y poscosecha.
La presentación explica qué tipo de indicadores se pueden usar para valorar la extensión rural.
La extensión rural es un proceso de trabajo y acompañamiento con el productor orientado al desarrollo sostenible de sus capacidades. En México, se han adaptado una serie de modelos de extensión que van desde el norteamericano, implementado a principios de la década de 1980, hasta el modelo de hub o nodo de innovación (plataforma - módulo demostrativo - área de extensión), aplicado desde el 2010 en el marco del Programa MasAgro. El objetivo de este documento es analizar los diversos procesos de extensión en México.
Rural extension is a process of work and accompaniment with the producer aimed to sustainable development of their skills. In Mexico, a series of extension models have been adapted, that goes from the US, implemented in the early 1980’s, to the hub model or innovation node (platform - demonstration module - extension area) applied since 2010 under the MasAgro Program. The aim of this paper is to analyze the various processes of extension in Mexico.
