Les approches agrosylvicoles, une réponse pour le renforcement de la résilience aux changements climatiques de la population locale de Luki

Abstract

The analysis of the different silvicultural methods by agroforestry approaches, as a response to strengthening the resilience of the local population of Luki to climate change in Luki, DRC, focused on regeneration and dendrometric inventories in plantations (= agroforests) within the RBL. An observation of the twenty most abundant woody forest species was made out of the total of 40 species present in the study sites. DBH, total tree height, and basal area within a chronosequence of plantations of different ages constituted the dendrometric characteristics of the study. Sampling plots were established within plantations in agroforestry systems of different ages, which were better identified by the site within RBL. The rotation period is long (>50 years). The conversion methods target stands where the need for a significant marketable volume (timber, fuelwood) is unavoidable The cuts are of the monocyclic type. Taking into account the technical routes employed by the different silvicultural methods implemented in Luki, we count seven agroforestry approaches. Silvicultural efforts were therefore focused on a group of trees grouped by species. The silvo-banana, silvo-coffee (Terminalia superba-Coffea robusta ‘petit-Kwilu’), silvo-safou (Terminalia superba-Dacryodes edulis), silvo-cocoa (Terminalia superba-Theobroma cacao), silvo-orchard (Terminalia superba-mixed fruit trees), agricultural crops under tree cover (CASCA), and others implemented in Luki are an application of the 'taungya' system
