Cacao provides an alternative to illicit production of coca for Colombian farmers

Problem

How can Colombian farmers make a sustainable living without growing illicit but profitable crops such as coca (the plant used to produce cocaine)?

  • Fifty-three years of civil war have negatively impacted the agricultural investments and growth of Colombian farms.
  • Disadvantaged farmers grew coca and marijuana either by force or because it was the only option during the conflict.

Findings

Plant scientists at Penn State are contributing their expertise on the genetics and the cultivation of the historical cacao plant to provide a road map for the post-conflict agricultural development of an alternative crop that is both profitable and sustainable. Cacao, the principal ingredient in chocolate, is native to Colombia, which already produces some of the finest-flavored cocoa in the world.

Impact

Cacao provides a new opportunity to support legal agricultural development in Colombia as the global demand for chocolate is continually increasing. The Cacao for Peace initiative provides training for the difficult-to-grow crop and seeks to make Colombia a major player in world cacao markets. By mapping the genetic diversity of cacao, the team will be able to trace early species of cacao to their origins and possibly identify the genes that are responsible for disease resistance.
