Here you will find an interactive map of sub-Saharan Africa’s remaining biodiversity intactness. The Biodiversity Intactness Index (BII) indicates the average remaining proportion of ‘intact’ populations of indigenous species, given the dominant human land uses and activities. A score between 0% and 100% is assigned to each ‘pixel’ across the region based on biodiversity experts’ advice on how various populations of species are affected by the land use and other human activities within that area. The map was produced by integrating ten spatial datasets to map the region’s land uses of varying intensity, which was then combined with bioregional lists of indigenous taxa and the bii4africa dataset of expert estimates.
Since it is designed to integrate data from a wide range of land uses, species and environments, the BII offers a holistic perspective on the state of biodiversity in a particular region. The BII can be calculated at different scales (for example, at a national, province or municipal level) and for different species groups (for example, for mammals, reptiles or plants).
