Evaluation de l'impact économique du cotonnier sans gossypol en Côte d'Ivoire
Abstract
Assessment of the Economic Impact of Glandless Cotton in Ivory Coast. This study presents the results of an ex-post assessment of the economic impact of glandless cotton introduced in farming system in north Ivory Coast. The researches on this type of cotton plant have been conducted since 1975 until now in Bouaké. From 1980 to 1995, the extension office has released new glandless cotton varieties. They were intended mainly to obtain a more competitive fiber on the world market as well as edible grain for animals (cakes) and for man (oil, flour). A surplus economic estimated model has been applied for this analysis. Upon the basis of the hypothesis retained in this analysis, the net present value estimated is negative. These results put in evidence the economic failure of the glandless cotton research and extension program in Ivory Coast. Furthermore, the lower productivity at farm level induced a decrease of total fiber and oil productions. This study presents three interests. Firstly by showing that it is possible to have a good idea about an ex-post assessment of public investment in agriculture. Secondly by showing clearly that an extension program success depends on its capability to solve farmer's real problems. Thirdly, it gives a good feed-back to agricultural researchers.
