protecting forests climate to regulate the The international negotiations on climate change bring the safeguarding and sustainable management of the tropical rainforests to the forefront. 12 to 15% of greenhouse gases (GHG) result from woodland clearance and degradation of the tropical forests following fires and tree felling. And vegetation growth contributes to reduction of the greenhouse effect through CO2 storage. Regarding the role of these ecosystems in climate regulation, the United Nations are planning the setting up in 2013 of a special scheme: REDD+ or “Reducing Emissions from Deforestation and Forest Degradation and the role of conservation, forest management and the growth of carbon stocks”. Although the methods of application have not yet been determined, this mechanism aims to pay those developing countries which succeed in preserving or expanding their forests. To achieve this, they must meet three criteria: avoid producing GHG emissions, take into account the forest carbon storage, adopt good governance and manage their forests. Assessment Assessment of the regulatory influence tropical rainforests exert on climate is complex and difficult. In French Guiana, research scientists are studying the carbon stored by the tropical rainforest and the changes of this store in forests used for their resources. The investigations will help define forms of forest usage that can reduce greenhouse gas emissions. Message issued by the Indonesian authorities aiming to control access to forests and their uses. Measuring carbon flux in the Guiana forest. Forest fire in the Amazon. Did you know? To produce 1 m 3 of its wood, half of which is made up of carbon, the tree processes 1 tonne of CO2 and thus helps alleviate climate change • Every year the forest destroyed is equivalent to of the surface area of France 19 MINISTÈRE DES AFFAIRES ÉTRANGÈRES ET EUROPÉENNES 1/4 FTH/en - 2011
