Agricultural education, research, and extension can contribute substantially to reducing rural poverty in the developing world. However, evidence suggests that their contributions are falling short in Sub-Saharan Africa. The entry of new actors, technologies, and market forces, when combined with new economic and demographic pressures, suggests the need for more innovative and less linear approaches to promoting a technological transformation of smallholder agriculture.
Este artículo presenta los resultados alcanzados durante el proyecto de investigación sobre buenas prácticas en gestión del conocimiento para el desarrollo basado en conocimiento, a partir de la aplicación de las tecnologías colaborativas Web 2.0 para la divulgación del conocimiento de personas, organizaciones y comunidades. Para el efecto se desarrolló un sistema web que pretende potenciar la inteligencia colectiva a través de las redes sociales, el acceso a aplicaciones en línea, la sindicación de contenidos, las folksonomías y los repositorios multimediales.
This study explores one of the most important questions for alleviating poverty in sub-Saharan Africa, why are advancements in agricultural technology not taking root in this region? Using data from deep interviews of 42 small-scale farmers in Ghana and Cameroon, a conceptual analysis of drivers and factors of agricultural technology adoption in this region is made and represented as causal loop diagrams. Interviews also provide a basis for weighting factors that farmers consider before adopting a new technology.
Although the benefits of genetically modified (GM) crops have been well documented, how do farmers manage the risk of new technology in the early stages of technology adoption has received less attention. We compare the total factor productivity (TFP) of cotton to other major crops (wheat, rice, and corn) in China between 1990 and 2015, showing that the TFP growth of cotton production is significantly different from all other crops. In particular, the TFP of cotton production increased rapidly in the early 1990s then declined slightly around 2000 and rose again.
Cet article présente une évaluation théorique de la performance urbaine des modèles alimentaires alternatifs dans la prise en charge des objectifs de développement durable (ODD) en vue d’améliorer la sécurité alimentaire urbaine. Elle concerne les modèles des systèmes alimentaires les plus relatés dans la littérature, à savoir le système alimentaire territorialisé (SAT), le City-Region Food System (CRFS) et le système alimentaire urbain intelligent (SAUI) en émergence.
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.
Sustainable intensification of agriculture will have to build on various innovations, but synergies between different types of technologies are not yet sufficiently understood. We use representative data from small farms in Kenya and propensity score matching to compare effects of input-intensive technologies and natural resource management practices on household income. When adopted in combination, positive income effects tend to be larger than when individual technologies are adopted alone.
Sustainability is becoming a pivotal guide for driving the governance strategies of value chains. Sustainable policy should have as its objective the perpetuation of production models over time to maintain its environmental, economic and social dimensions. Therefore, measuring the sustainability of a production system is fundamental to deepening the understanding of ongoing trends, considering the pressure exerted by agricultural policies, market dynamics and innovations introduced in the production system.
The objective of this piece of work is to explore innovation support in the case of Greece which is a particular one given the demise, on the one hand, of the country's public extension service in the early 1990's - and since then the absence of any kind of organized extension intervention in the country, and, on the other hand, of the agricultural cooperatives; thus the extremely weak and fragmented nature of the Greek Agricultural Knowledge and Innovation System which seems to be rather unique in the European Union
Con el objetivo de conocer las estrategias de comercialización de Walmart y las oportunidades de desarrollo de los pequeños productores hortícolas, se realizó un estudio en Acatzingo, uno de los principales municipios hortícolas del estado de Puebla, México. Se concluye que las negociaciones directas que establece Walmart con los pequeños productores hortícolas, la supresión de un eslabón de la cadena de valor del sistema hortícola y la manipulación de los precios de las hortalizas, son estrategias que apuntan hacia la hegemonía de esta cadena de autoservicio en el sistema hortícola
