Regressive dynamics of coffee agroforestry systems: determinants and effects on system composition and structure in Cameroon
The aim of this study was to analyse the structure and diversity of coffee agroforestry systems, with an emphasis on the spatial dynamics of land use in the different coffee production basins and agro-ecological zones and their associated determinants in Cameroon. Satellite image data, field inventories in eighty-one (81) 40 × 40 m plots, as well as surveys of 240 producers, were conducted. The results showed that the largest conversions and changes in land use occurred during the period 2001–2019, with a reduction in agroforestry and forest cover and an expansion in the area covered by other crops. In total, 49 woody species divided into 24 families, were inventoried in the coffee agroforestry systems. The importance value index reveals that Elaeis guineensis (28.5%), Dacryodes edulis (25.9%), Persea americana (17.5%), Leuceana leucocephala (15.8%), and Mangifera indica (12.4%) were the most important. The diversity indices show that the systems in the forest zones (Mungo and Haut-Nyong) were more diversified than those in the humid highland savannah (Noun); however, the density of woody plants is higher. The diametric structure of coffee trees, characterized by the limited presence of young coffee trees, reflects the low level of renewal in the coffee agroforests in all the production basins, where some farmers replace dead or unproductive coffee trees with other crops, such as Theobroma cacao, Elaeis guineensis, Musa spp. and fruit trees. This is due to a number of constraints faced by the producers, and the analysis indicated that the main variables that significantly predicted the susceptibility of the farmers to adopt an intervention strategy of preservation or conversion of the agroforestry system were farm size and farm age. Taking these variables into consideration is necessary for decision-making and for the development of coffee agroforestry systems in similar contexts.
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
