Assessing smallholder farmers’ motivation to adopt agroforestry using a multi-group structural equation modeling approach por Buyinza, J., Nuberg, I.K., Muthuri, Catherine W., Denton, M.D.

“…Farmer motivation resulting from social pressure was strongest among farmers who had never interacted with the project, and in the absence of project interventions, rely on existing social structures to drive change in their community. Farmers’ perceived behavioural control to overcome tree planting barriers and their attitude to the economic benefits of shaded coffee were significantly different among the four farmer categories (p < 0.05). …”

Adoption of complementary climate-smart agricultural technologies: lessons from Lushoto in Tanzania por Ogada, Maurice Juma, Radeny, Maren A.O., Recha, John W.M., Solomon, Dawit

“…However, agricultural production and productivity remain relatively low, with significant yield gaps attributed to factors such as limited access to and low adoption of appropriate agricultural technologies, and climate-related risks resulting from climate variability and change. This paper explores the drivers of adoption of climate-smart agricultural (CSA) technologies and practices, taking into account the complementarity among agricultural technologies and heterogeneity of the farm households, using data from Lushoto in Tanzania. …”
