The environmental effectiveness of Central African management plans has recently become a topic of debate. The first discussion focused on additional deforestation connected to concessions with a management plan, as opposed to concessions without. Conclusions of an article published in early 2016 that supported this debate were challenged by researchers who pointed out certain choices judged arbitrary and proposed other ways to measure effectiveness. The sustainability of managed exploitations also became a subject of debate. The uncertainty of the recovery of several major commercial species after several rotations challenges the idea of sustainable management. However, since this process requires several decades, due attention must be given to the evolution of the market, technical progress and possible changes in the method governing the very long-term use of the forest ecosystems. Sustainability is still an open, unresolved question.
