What Are the Impacts of Deforestation on the Harvest of Non-Timber Forest Products in Central Africa?

摘要

The objective of the study is to evaluate the impact of forest transition on non-timberforest product (NTFP) harvesting in Central Africa. We analyze the evolution of several parameters,including distance from NTFP harvest site to road, proportion of dietary intake and villagers’ incomes.The research is based on field surveys, participatory mapping and the geolocation of activities in threestudy sites representing different stages along the Mather’s forest transition curve: (i) intact forest;(ii) partially degraded forest; and (iii) small areas of degraded forest with plantations of useful trees.The results show that the maximum distance from harvest site to road is higher in Site 2 comparedto Site 1 as a consequence of a lower availability of NTFPs; and that this distance is significantlylower in Site 3 due to a drastically smaller village territory. The diversity of bushmeat decreases asgame evolves from large to small species, commensurate with the progression of forest transition.As a consequence, there is also a reduction in the proportion of these products represented bothin household dietary intake and cash income. This analysis establishes a strong link between theMather’s forest transition curve and a decline in the importance of NTFPs in village productionand livelihoods.
