Surprisingly, given the significant issues, it was not until the end of the 2000 decade that greater development efforts were significantly focusing on agricultural training and that the challenge of the installation of young farmers were emerging at a global level as a public policy issue and development support. While training and support initiatives in agricultural and rural installation are thriving nowadays in many Southern countries, there is an urgent need to acquire a better understanding of the installation conditions of farmers, to discuss the forms and modalities of its support and to analyse the effects of the existing schemes. In this context, the first part of this article provides an analysis grid that seeks to understand the installation process of youths in family farming and to analyse the effects of the training and support schemes on youths, their families and local environments. In a second part, this method is mobilised to analyse the process of installation in agriculture of youths trained by three integration training schemes: the Collèges Agricoles (Agricultural High school s ) of FEKAMA in Madagascar, the AFOP national programme in Cameroon, the CIDAP in Togo.
