Résumé
Agroforestry systems play a vital role in providing ecosystem services that support both human well-being and ecological functions. However, the specific contributions of these traditional land management to local communities and biodiversity conservation remain understudied, particularly in the context of protected area conservation. This study investigates traditional agroforestry systems and their associated ecosystem services in the vicinity of Pô-Nazinga-Sissili protected area in Burkina Faso. Using a stratified sampling approach considering gender and residential status, semi-structured interviews were conducted with 71 farmers. The Millennium Ecosystem Assessment framework was employed to categorize the identified ecosystem services. The Citation Frequency (CF) metric was calculated to quantify the relative importance of each ecosystem service. The data were processed using IBM-SPSS version 20. The findings reveal a predominance of the Kasséna ethnic group (75 %), with significant portions of the surveyed population being non-literate (76 %). Three land tenure systems were identified in agroforestry systems: inherited land owned by native farmers (46 %), land loans used by migrant farmers (52 %), and a minimal presence of land rentals (2 %). The study identified 12 types of ecosystem services provided by traditional agroforestry systems, with provisioning services being the most frequently cited. Food production (96 %), fodder (17 %), and medicinal resources (10 %) were the primary ecosystem services reported. Parklands dominated by Vitellaria paradoxa were the most prevalent traditional agroforestry system, occurring in approximately 96 % of cases. Other significant tree species contributing to ecosystem services included Parkia biglobosa, Afzelia africana, Tamarindus indica, Piliostigma thonningii, Detarium microcarpum, Lannea microcarpa. The findings provide valuable insights into the multifunctionality of traditional agroforestry system, highlighting their crucial role in supporting local livelihoods and ecosystem health. Further research is recommended to explore the potential for enhancing and sustaining these agroforestry systems in the face of environmental and socio-economic changes.
