What This Presentation Shows: Biodiversity underpins all ecosystem processes and is the foundation of Kenya’s rich natural heritage. This ppt presents maps depicting both the breadth of Kenya’s biodiversity and current pressures and trends affecting it. An initial set of maps outlines Kenya’s endowment of mammals and the areas important for bird conservation. Maps showing agricultural cultivation and development of water sources in the rangelands then depict landscape-level pressures on Kenya’s biodiversity. While agriculture is a signiﬁcant factor in biodiversity decline, not all cropping has to be detrimental. A set of maps shows where farmers in central and western Kenya are making a positive contribution to biodiversity through crop selection and farming practices. The next series of maps shows how Kenya’s diversity of rangeland species has been affected by human pressures. Maps showing the distribution of large grazing mammals in the rangelands reveal severe contractions in the size and distribution of wildlife populations since the 1970s, identifying areas that have witnessed declines in wildlife numbers and wildlife density. However, the maps and tables also indicate that not all the news about Kenya’s rangeland species is bad. Two examples show a reversal in trends: the recovery of wildlife populations in Laikipia District and the stabilizing of elephant numbers. These demonstrate that national-level policies, community-based conservation efforts, and changes in local land use patterns can lead to outcomes that are more supportive of Kenya’s unique biological endowment.
Summing Up: Biodiversity—the full variety of plants, animals, and microorganisms found on Earth—is the source of many benefits crucial to human well-being. It provides the underlying conditions necessary for the delivery of ecosystem services.
