Peanut is a major source of income for many farmers in Senegal. However, this sector faces several problems in all the segments of the value chain such as yield decline and serious market disturbances. Agricultural production has to be increased to address these issues. This can be done by reinforcing the connectivity of farmers. This study aims to evaluate connectivity as a catalyst for agricultural productivity. An appropriate measure of connectivity integrating various dimensions is computed and an estimate of multilevel mixed-effects linear regression shows its positive and meaningful effect on the output. Results show that Information and Communication Technologies should be promoted and social networks should be reinforced in agricultural activities. One option is to help Rural Producer Organizations better develop and to be a gateway as community access points.
