INNOVATION can be defined as a socio- technical process appropriate to rural companies in which can be distinguished: (l) The invention or find (herbicide,organization,culture...) which can be the fact of a farmer, a researcher, an actor of the field, (ii) The innovation which can be, defined as a new practice (Schumpeter, 1935). The innovation is thus a process which values invention by integrating it into a system of production. The diversification of the agricultures on the horticulture of export comes under this process. We propose (Temple and Sibelet, on 2005) to qualify the socioeconomic conditions of its realization and to conceptualize it by a grid of analysis.
