Those farmers who are not well integrated in the market encounter difficulties in the development of their agriculture (Ndjeunga and Bantalin 2005). To develop sustainable agriculture, infrastructures and means of communication such as roads and telephones must be established. The use of inputs is often difficult in arid zones because of poor road conditions.  This increases the price of inputs and reduces the price of agricultural products. It is also difficult to have access to inputs at the appropriate time where road and communication infrastructures are not well developed. 

The development of mobile networks is a true revolution in Sahelian countries. This facilitates communication and farmers’ participation in the market. Price information is particularly easier to obtain.
