Heterogeneous pathways of technological change in marginalised rural areas: the case for fuller accounts of adoption

Dynamic and cumulative processes shaping technology adoption receive less attention in agricultural research compared to snapshot analyses of its determinants. We address this through theory-driven evaluation and the Propositions, Encounters, Dispositions and Responses framework. In 2005, research institutes introduced improved cassava varieties (ICVs) in East Cameroon. In the following decade, economic transformations brought in new development actors who revived their circulation. The interactions and actors who intervened in a relatively short period and the diversity of adoption pathways in a relatively small area highlight the complexity of technological change. Learning-oriented, systemic and systematic evaluations are needed for fuller adoption accounts.
