Complémentarité des filières sorgho sucré et canne à sucre en Haïti: évaluation des conditions de développement sectoriel d'une innovation

Abstract

We examine how sweet sorghum implementation in Haiti could be a successful innovation. The hypothesis is that sweet sorghum multiuse would permit the combination of its several uses: in food industry (grain, fodder), energy producing (biofuel or cooking gel and cogeneration) and potable alcohol value chain. We mobilize an analytical frame of reference of value chains to study in itinere the conditions for a sectorial development of an experimental implementation. The data were collected from face-To-face surveys with experts. The results revealed that the functioning of sugar cane industry determines specific constraints, conditioning the choice of sorghum varieties. These results highlight a possible complementarity between the use of sweet sorghum grain for food or feed and its use to produce potable alcohol. They interrogate the potentialities of using sweet sorghum grains and co-products in animal diet. They invalidate the use of sweet sorghum juice for biofuel.
