Abstract

Cameroonian agrarian landscapes are characterized by various agricultural and agroforestry practices. These agroforestry practices in particular are unfortunately disrupted by various pressures and effects of climate change. Few works have emerged contribution and the relevance of ecological interactions of plant associations in the conservation of diversity and dynamics of vegetation in the forest-savannah ecotones of central Cameroon. The overall objective of this work is to demonstrate the effectiveness of ecological interactions of agroforests.in the conservation and dynamics of vegetation in these ecotones. To do this, a participatory analysis was carried out with 74 farmers spread across five villages in Ndikiniméki for a sampling rate of 7%. Botanical inventories were carried out and the data collected were subject to various analyzes (analysis of variance, correlations, multivariate tests and dendrograms). Our results show a large specific variability (1626 individuals) for a total basal area of 13.66 m2/ha. Diameter and height classes are very heterogeneous and show respective peaks in the classes of [30–40 cm] and [≥ 50 cm] and higher values in the height classes [< 10 m] proof of good reconstruction of the local flora. Jaccard proximity index and correlation matrix reveal strong similarities between the floristic components of the different agroforests in the area. The Agroforests of medium architectural type (41.09%) characterize the agrarian landscape of this area and show 2 categories of associated woody species (introduced and native) divided into 3 functional woody types, namely: species of socio-economic interest high density (EIS1), low density (EIS2) and local species and pioneers of reforestation (ELPR). The typology of these agroecosystems shows 2 characteristic architectural profiles and 4 groups of agroforests with strong similarities.

期刊介绍: Agroforestry Systems is an international scientific journal that publishes results of novel, high impact original research, critical reviews and short communications on any aspect of agroforestry. The journal particularly encourages contributions that demonstrate the role of agroforestry in providing commodity as well non-commodity benefits such as ecosystem services. Papers dealing with both biophysical and socioeconomic aspects are welcome. These include results of investigations of a fundamental or applied nature dealing with integrated systems involving trees and crops and/or livestock. Manuscripts that are purely descriptive in nature or confirmatory in nature of well-established findings, and with limited international scope are discouraged. To be acceptable for publication, the information presented must be relevant to a context wider than the specific location where the study was undertaken, and provide new insight or make a significant contribution to the agroforestry knowledge base
