The transformation of the peasant economy in Colombia has been influenced by the armed conflict, the crisis of the agricultural development model, and the illegal crops.
Pueblo Nuevo, in the municipality of Briceño (Antioquia), has experienced the expansion of armed conflict scenarios, undergoing radical transformations in its economic and social relations. The article traces the local economy reconfiguration since the Havana Accords (2016), decisive in peace-building and in a differentiated approach to the problem of coca production, with special reference to the pilot project of voluntary substitution of illicit crops and its connection with the socioeconomic reconstruction in the period 2016-2019. By a theoretical-qualitative approach from the peasant economy perspective, and according to a geographical-economic and historical reading of the case, the determining factors and dynamics of the process are identified, once again highlighting the institutional barriers to a sustainable productive transformation of these territories.
