Human distributions and modeled present and future malaria vector distributions in Africa. Maps showing the basic panorama of human distribution across Africa, as well as modeled present and future distributions of the two major malaria vectors across Africa, Anopheles gambiae and A. arabiensis. Human population is shown as white – 0–25 persons, gray 26–441, pink 442–857, red 858–1273, dark red >1273. Mosquito species distributions: gray = areas modeled as suitable both at present and in future projections; blue = areas presently modeled as suitable, but that are not projected as suitable under future conditions; red = areas expected to become newly suitable for mosquito species under future conditions.
