We examine the environment as a mechanism for building substantial integration in Colombia. In environmental peacebuilding, substantial integration is a positive peace dimension characterized by trans-societal links that foster social cohesion. Employing data from the Amazonian Department of Caquetá, we argue that the Government of Colombia is pursuing a peacebuilding approach that impedes opportunities to forge an inclusive social order. Instead, it has forcibly integrated frontier communities to advance an extractive peace that perpetuates longstanding patterns of resource violence.
