How it works
The Biodiversity Intactness Index (BII) assigns a score to 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. 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 adjusted in scale and purpose (for example, at a national, province or municipal level).

The main output for this project will be an interactive map of BII across sub-Saharan Africa. This map will also feature insights from contributing biodiversity experts regarding the landscape changes they are seeing in their regions, and the implications for both biodiversity and people.

The data will be published open-access. The project will also publish insights into the link between the BII and the biodiversity planetary boundary, and linkages to human well-being across the continent.

The bii4africa dataset of faunal and floral population intactness estimates across Africa’s major land uses

Here you will find the open-access bii4africa dataset, which was co-produced by 200 contributing experts in African biodiversity. It contains intactness scores representing terrestrial vertebrates (tetrapods: ±5,400 amphibians, reptiles, birds, mammals) and vascular plants (±45,000 forbs, graminoids, trees, shrubs) in sub-Saharan Africa across the region’s major land uses and intensities.
