Industrial forest concessions cover about 45 million hectares in Central Africa. This paper discusses the weaknesses of the current concession model and initiatives for helping it evolve; it then proposes a new type of concession, entitled ‘Concessions 2.0’, adapted to the future challenges presented by the overlapping among the rights and modes of the harvesting of multiple resources. This proposed model is based on four features: (i) mapping and recognition of the customary territories within and around the industrial concession, (ii) timber revenue sharing indexed on the extension of the customary territories and contractual management agreements within the communities, (iii) allowance of commercial exploitation of non-timber resources by entitled claimers under the supervision and/or in association with the concessionaire, and (iv) inclusive governance for the management of overlapping rights over the concession area.

Pericopsis elata (gregarious Fabaceae), a moist semi-deciduous hardwood logged in Central African forests, is on the IUCN Red List and in CITES Appendix II. Our study evaluated its main ecological and pedological parameters in Cameroon. We obtained a mean diameter increment of 0.32 ± 0.04 cm.year–1. Minimum fertile and effective fruiting diameters were 32 and 35 cm, respectively. Flowering started in March-April, and fruits ripened over 7 months. Seed rain was studied in 1 × 45 m cleared corridors in each cardinal direction around 4 isolated mother trees. Indehiscent pods (average weight: 131.6 ± 10.1 cg) were dispersed mainly to the west: 86% of the variation of the number of collected fruits could be explained by the distance to the mother tree and the direction (GLM analysis, p < 0.001). The proportion of seeds eaten by insect larvae depended on the mother tree (10–95% – χ2 test, p < 0.001). Soils were compared at a regional scale: soils with P. elata contain higher levels of C (2.2 ± 0.5 SD- g.100g–1), Fe (261 ± 83 mg.kg–1), and P (33 ± 10 mg.kg–1), and were more acidic (pH 4.0 ± 0.2). A planting method in logging gaps is currently being tested taking into account physicochemical soil parameters [less ▲]
