Dans cet article, un modèle économétrique de la fonction distance multi-outputs a été utilisé pour analyser les effets des services sociaux sur l’efficacité technique des exploitations agricoles burkinabè. Les résultats montrent que le nombre d’années d’éducation formelle reçu par le chef de ménage, l’expérience de la pratique agricole, la fréquentation des centres de santé moderne et les services de soutien à la production agricole ont des effets positifs significatifs sur l’efficacité technique.

The United Nations Economic Commission for Africa (2016) calls for resources for the implementation of the Action Plan for Accelerated Industrial Development in Africa, and states that: “Industrialization is essential for African countries as a means of increasing income, creating jobs, developing value-added activities and diversifying economies”. The United Nations Development Program (UNDP), the African Development Bank (AFDB), and the Organization for Cooperation and Economics Development (OCED, 2014, p. 16) explain the benefits to African countries’ participation in Global Value Chains (GVC) to industrialize without having to implement all stages of the chain. They add that the acquisition of new production capacities can allow countries and companies to move upmarket, which is to say to increase their share of value added in a GVC. But the opposite is the case, at least in some countries like Burkina Faso. We are witnessing a “specialization of primary products (cotton and non-monetary gold), to the detriment of manufacturing industry with high potential for multiplier effects on local economies” National Plan for Economic and Social Development of Burkina Faso (PNDES, 2017, p.12). Cusolito and al. (2016) mention that overcoming a series of obstacles (such as bad policies and governance, insufficient technology and skills) is the way to actively participate in GVCs. Yet OPEN it is these same obstacles that have always prevented the industrialization of Sub-Saharan Africa (excluding South Africa). The results show that the Global Value Chains (GVC) contribute to the creation of added value in developing countries what has an effect on industrialization

This study shows that farmers in arid and semi-arid land can improve their efficiency if they have access to agricultural extension services. An exhaustive survey was used to obtain data from 423 cotton producers in the arid zones and 144 of wetlands in Burkina Faso. The method of the directional distance function modeling a multi-output technology was used. The results show that cotton farmers in the arid zones are not technically more inefficient than those in wetlands. On average, arid zone producers have a technical inefficiency of 0.056 while that of wetland producers is around 0.052. The agricultural extension, defined as receiving visits and advice from technical agents, is important for producers because it helps farmers choose soil and water conservation techniques and fertilizers adapted to the Agro-climatic conditions of their respective zones. Agriculture extension also helps farmers of the arid zones to reduce their technical inefficiency by advising them to cultivate small agricultural plots. On average, in these zones, the size of an agricultural plot is around 1.03 ha compared to those of wetlands which is about 1.6 ha.
