Abstract:
The main objective of this study is to conduct an analysis of agro-food chains, and show their
impact on agriculture in a region that has great agricultural potential for intensification and
diversification. The identification and action of actors involved in agricultural upstream and
industrial downstream are central to this research.
In the wilaya of Guelma, agri-food industries have developed rapidly and their activities cover a
large part of its territory. These sectors have experienced a development in terms of areas,
production and yields. From now on they contribute to the formation of an original agro
industrial center with the appearance of industrialists putting into practice innovative techniques
and elaborate forms of management.
Our empirical application in the wilaya of Guelma has shown that each sector has its own
characteristics and that it is totally different from the other sectors, whether in its agricultural
upstream or in its industrial downstream.
