An heuristic framework for identifying multiple ways of supporting the conservation and use of traditional crop varieties within the agricultural production system por Jarvis, Devra I., Hodgkin, T., Sthapit, B.R., Fadda, Carlo, López Noriega, Isabel

“…First, any description or analysis within the four main areas (assessment, access, use and benefit) can, and most probably will, lead to a number of different actions. Second, the decision to implement a particular action, and therefore its success, will depend on farmers and the farming community having the knowledge and leadership capacity to evaluate the benefits that this action will have for them. …”
