Ecological transition of an innovation model: Yam seed production in Haiti

Boyer J., Temple L.. 2018. In : Temple Ludovic (ed.), Compaore Sawadogo Eveline M.F.W. (ed.). Innovation processes in agro-ecological transitions in developing countries. Londres : ISTE, Wiley, p. 95-116. (Innovation, Entrepreneurship, Management Series, Innovation in Engineering and Technology Set, 2).

This chapter shows how the transition of a linear innovation model to an iterative, participatory and ecological process has modified a technology and allowed it to be adopted. This case study is based on seed multiplication technology of yams in Haiti, the Miniset technology. We analyzed the development of this technique between 1990 and 2012, carrying out interviews with 26 experts (researchers, technicians, NGO leaders, farmers, etc.) and surveys of 106 farmers in three yam production regions of Haiti. We show how the failure of a linear technology model transfer allowed producers to improve this technique and how this and the greening of the technology paved the way for successful adoption of the technology. This success has been instrumental in increasing the production of yams in Haiti and producers' incomes.
