Facteurs socio-économiques influençant la biodiversité ligneuse des parcs agroforestiers de deux villages du plateau central du Burkina Faso | Influence of socioeconomic factors on the biodiversity of woody species in agroforestry parkland systems: A case study in two villages in the central plateau of Burkina Faso

Agroforestry parklands face strong pressure from the increasing population of the region. The World Agroforestry Centre (ICRAF Sahel) started a biodiversity project with the objective of developing methods to conserve biodiversity and to improve the situation of the poor rural population. In this context the present study examined the influence of land use unit and the prosperity classes of farmers on the biodiversity of woody species. A wealth ranking classification was carried out and applied to the households of two villages in the central plateau of Burkina Faso using the "Participatory Analysis of Poverty and Livelihood Dynamics" (PAPoLD) method. Thirty farmers of different prosperity classes were chosen and inventories carried out on their different land use units. Statistical analyses show an increase in biodiversity from the village housings. However, no significant influence on biodiversity was observed in connection with a farmer's prosperity class.
