The document refers to the main species of yam Dioscorea alata, D. rotundata/cayenensis y D. trifida as well as to the some very common but serious problems experience by farmers. As a concrete measure to elevating these constraints, a yam development project was created by the Ministry of Agriculture together with IICA as a framework for technology generation and transfer. This project aims to increase the supply of yam for both the export and local markets to increase the number of farmers involved in its cultivation. The last paragraph enphasizes that co-operation and co-ordination is a necessary and important factor within this framework and thus it is of great importance that linkages among different institutions involved in yam research and development in the Caribbean by strengthened.
