This paper shows that the current generation of transgenic crop varieties has significant potential to improve economic welfare in low-income countries. These varieties might increase crop yields in low-income countries in cases when pesticides have not been used. They will reduce negative health effects of chemicals when they replace them. With low transaction costs, appropriate infrastructure, and access to intellectual property, multiple varieties of transgenics will be introduced.
This paper analyses a biotechnology-focused project which aims to promote the development and adoption of tissue culture bananas by small-scale farmers in Kenya. The paper highlights the generation of several important narratives that are used to justify the development and dissemination of this technology. First, a disaster narrative, a series of claims regarding rural livelihoods and banana production in Kenya, is generated. This creates a political and technical space for the creation of a new science that can solve these problems.
L’édition annuelle de Défis Sud propose un regard sur les agricultures, avec des faits, des chiffres et des prévisions. Face à l’augmentation de la population, au réchauffement climatique et à la perte de ressources naturelles, les solutions proposées pour répondre au défi de la sécurité alimentaire mondiale devraient davantage miser sur l’agriculture familiale et l’agroécologie. En 2018 les agricultures familiales seront encore menacées.
Source majeure d’alimentation pour une grande partie de l’humanité, les céréales étaient au coeur de la crise alimentaire en 2008. Elles sont de nouveau en première ligne. Aujourd’hui, les changements de modes de consommation des pays émergents, ainsi que la demande artificielle en agrocarburants, accentuent les problèmes liés à l’offre de céréales.
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 trabajo busca evaluar el impacto de las Escuelas de Campo en familias y fincas cacaoteras de Upala y Talamanca (Costa Rica).
El propósito del presente estudio de caso es documentar un proceso de Investigación Agrícola para el Desarrollo (IAD): las ECAS de MAP en Trifinio, el cual analiza la experiencia del Proyecto Innovaciones en Cadenas de Valor de Hortalizas Epeciales. Asimismo resalta los principales logros y lecciones aprendidas, que sirven como un ejemplo tangible de un impacto positivo en la vinculación de IAD con la innovación, el desarrollo y el papel que pueden desempeñar las políticas y mecasnismos institucionales para promover esta relación
There have been repeated calls for a ‘new professionalism’ for carrying out agricultural research for development since the 1990s. At the centre of these calls is a recognition that for agricultural research to support the capacities required to face global patterns of change and their implications on rural livelihoods, requires a more systemic, learning focused and reflexive practice that bridges epistemologies and methodologies.
The farmer field school (FFS) concept has been widely adopted, and such schools have the reputation of strengthening farmers’ capacity to innovate. Although their impact has been studied widely, what is involved in their scaling and in their becoming an integral part of agricultural innovation systems has been studied much less. In the case of the Sustainable Tree Crops Programme in Cameroon, we investigate how a public–private partnership (PPP) did not lead to satisfactory widespread scaling in the cocoa innovation system.
The paper explores the strength of social networks in the agricultural innovation systems (AISs) in Ghana and the effect of AISs on adoption of improved farm technology. The paper uses social network analysis (SNA) tools to identify, map and analyze the AISs and the two-stage Heckman selection model. Combining qualitative and quantitative methods allows testing the differential effects of social networks on technology adoption in the Ghananian Plantain Sector
