L'échec de la croissance de la productivité agricole en Afrique francophone

  • Guy Blaise Nkamleu

[fre] Cet article explore l'évolution de la productivité du secteur agricole des pays d'Afrique francophone. Dans cette étude, la performance du secteur agricole de huit pays francophones est analysée par la méthode de la courbe enveloppe. Utilisant des données panel de 1970 à 2000, la construction de programmes mathématiques a permis de mesurer les index de Malmquist de la productivité globale des facteurs. Durant cette période, il a été observé que la productivité globale des facteurs a, dans l'ensemble, connu une évolution négative dans les pays échantillonnés. Une décomposition de cette mesure montre que la faible performance de la productivité est imputable à un retard technologique, l'évolution du niveau d'efficacité technique ayant été relativement satisfaisante. L'échantillon et les données utilisées laissent apparaître que, globalement, la dévaluation a eu un effet positif sur le secteur. Une comparaison entre pays forestiers et sahé- liens montre que les pays forestiers ont globalement été plus performants au cours de la période. [eng] The failure in agricul tural productivity growth in african french speaking countries - This paper examines changes in agricultural productivity in 8 French-speaking countries. The relative performance of agricultural sector was gauged using data envelopment analysis. From a panel data set of the 8 countries, which included the 30-year period 1970-2000, mathematical programming methods were used to measure Malmquist indexes of total factor productivity. It was found that, during that period, total factor productivity have experienced a negative evolution in sample countries. A decomposition of those measures suggest that, most of the weak performance of factors productivity is attributable more to technological change than technical efficiency change. Sample data showed that devaluation of Cfa franc have had a positive impact on the sector. We also found that compared to non- sahelian countries, sahelian countries have experienced a weak performance of their agricultural sector during the period 1970-2000.
