Essais sur la Productivité Agricole en Afrique Sub-Saharienne

Abstract : This thesis aims at analyzing agricultural productivity growth through innovations in agriculture and estimate its impact on off-farm employment in Sub-Saharan Africa. Applying the Stochastic Frontier Analysis (SFA) on historical crop production data, we find the average growth rate of agricultural productivity estimated at 1.9% per year for the entire period ; and at 3.13% this last decade mainly led by technical change. Scale efficiency change has been the major barrier to TFP growth in the African agriculture. Potash fertilizer, urea, and irrigation systems have a positive and significant influence on agricultural productivity growth as far as yield-increasing innovations are concerned. Crop diversification, as profit-enhancing innovations, has a positive and significant effect on agricutural productivity growth. The results of the panel VAR model depict a causal relationship with single direction from agricultural productivity to off-farm employment. Between agricultural productivity and inequalities, causality functions from productivity to inequalities. Therefore, productivity growth generates an increase of off-farm employment and significant inequalities in the distribution of income, but necessary to investments growth in agricultural sector. The results of GMM system with the FOD transformation allow us to identify, income distribution and product price change as the main channels through which agricultural growth affects the off-farm employment level. To address slow productivity growth and redundant jobs in the African agriculture, policies implications are oriented towards improvement of agricultural production system and labor specialization.
