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
The purpose of this article is to assess the inclusivity of on-farm demonstration across Europe, in relation to age, gender, and geographical location of participants. The paper is based on a survey of 1162 on-farm demonstrators (farmers and organisations) and three supraregional workshops. Overall, on farm-demonstrations were found to be engaging young(er) farmers who are at a career stage of being able to implement long-term innovations. However, across Europe demonstrations were primarily attended by men.
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.
