A map of the world's forests to support the EU Regulation on Deforestation-free Supply Chains
07/05/2024
The EU Joint Research Centre recently published an open-access global map of forest cover. CIRAD contributed to the map, which provides an explicit representation of forest presence to support the EU Regulation on Deforestation-free Supply Chains that will apply to EU member States as of 30 December 2024.

Plant succession is part of an ecological as well as social dynamic
30/04/2024
Many consider succession to be a matter of plants and purely plant ecology, and to remain, to say the least, non-human. A fascinating synthesis, co-authored by Bruno Hérault, a member of the UPR Forêts et Sociétés, reveals just how truncated such a view remains. The results have been published in the journal Ecosphere.

Industrial logging concessions have no impact on deforestation and forest degradation in the DRC
23/04/2024
A recent study conducted in the Congo Basin, home to the world's second largest continuous tropical rainforest after the Amazon, finds no evidence that logging concessions in the DRC increase or decrease deforestation and forest degradation. The same study also shows that there is no evidence that logging concessions reduce deforestation in areas of high deforestation pressure.

Agroforestry contributes to the well-being of rural populations in East Timor
02/04/2024
Many countries have integrated agroforestry into their sustainable development policies, particularly in Southeast Asia. In Timor-Leste, the national strategy for promoting agroforestry adopted a modern, technical approach focusing on crop rotation, intercropping and agro-sylvo-pastoralism. In so doing, it has largely overlooked the pre-existence, diversity and performance of traditional agroforestry systems (AFS). But what exactly are they? This is the question posed by Marguerite Cogné and Guillaume Lescuyer of the UPR Forêts et Sociétés.

Ultraviolet light has no effect on the evolution of trees
04/03/2024
A study published in the journal PNAS reveals that the sun's UV rays are not the main driving force behind mutations in trees. Sylvain Schmitt is interviewed about this breakthrough in the France Culture morning show.

Soil underpins the proper functioning of ecosystems: lessons from Côte d'Ivoire
06/02/2024
Soil is more than just a support: it must be in good health if agricultural activities are to be established and survive. In Côte d'Ivoire, the Ministry of Agriculture has brought together farmers, political decision-makers and scientists to take practical action to ensure the sustainability of soil in West African forest landscapes. The participants put forward their recommendations on combating deforestation, reducing the use of pesticides and agroforestry.

Which of life traits and ecosystems are most important in structuring the distribution of native and exotic birds within landscapes? This question has been addressed by a number of researchers familiar with landscape ecology and ornithology on Réunion Island.

What are the criteria for "agroforestry cocoa" from Cameroon?
16/01/2024
Agroforestry cocoa has been the subject of much debate in recent years, but this discussion is almost always based on experiences in West Africa. Other agroforestry practices exist, such as in Central Africa, which need to be better documented to illustrate and enhance the diversity of agroforestry cocoa.

Improved monitoring of the spatio-temporal diversity of mangrove trees and distribution patterns
07/11/2023
Spatio-temporal information on species assemblages in natural, disturbed and rehabilitated mangroves is an essential prerequisite for effective biodiversity conservation and management strategies. However, appropriate sampling strategies in the field due to spatial heterogeneity still hamper the detection of species distribution and temporal evolution. An increasing amount of remote sensing data seems to be the ideal way of meeting these challenges.

Understanding the response of commercial tree species to fire is essential for designing sustainable forest management strategies in West Africa. In this area of heavy deforestation for agriculture, semi-deciduous tropical forests have been reduced to a trickle over the last 50 years, and are now subject not only to logging but also to increasingly frequent fires.
