Current research concerning conservation agriculture in Africa has indicated that numerous socio-economic, biological, and cultural factors may hinder its adoption and scalability. However, a severe knowledge gap about these conditions that serve as obstacles or catalysts for adoption exists in the developing world context. This paper describes the Qualitative Expert Assessment Tool for CA Adoption, a means by which to understand and predict CA adoption in Africa according to scale: field, farm and village, and region. This tool has been tested in Tunisia, Madagascar, Tanzania, Zimbabwe, and Burkina Faso and is currently ready for use in all of Africa.
