Previous international and national policies have, for various reasons, failed to prevent deforestation in developing countries. REDD+ incorporates some of these past policies, but also some innovations. Lessons from past experience will need to be taken on board and new alliances will need to be forged if REDD+ is to be successful.

REDD+ projects require an impact assessment approach to estimate emissions and removals; for REDD+ to succeed we need information on this and the associated 3E+ outcomes. There are few examples of rigorous impact assessment in the conservation, avoided deforestation and payments for environmental services (PES) literature. REDD+ impact assessment could contribute tremendously to our understanding of successful environment and development policy initiatives. We will learn more rapidly and effectively by sharing evaluation designs and findings across REDD+ projects

This publication has two objectives. First, it analyzes the past research on deforestation and summarizes the findings of that research, in terms of its relevance to the development of future REDD regimes. Second, it highlights areas where future research and methodological development are needed to support national and international processes on avoided deforestation and degradation.

L es gommes en général et la gomme arabique en particulier sont des produits de base qui font l’objet aujourd’hui d’un commerce international florissant et le développement de la filière des gommes au Burkina Faso pourrait contribuer à lutter contre la pauvreté en milieu rural. C’est dans cette perspective que plusieurs initiatives ont été lancées depuis la fin des années 70.
