African protected areas surveyed

The EU-funded “Assessment of African Protected Areas” is out:

The purpose of the work is to provide to decision makers a regularly updated tool to assess the state of Africa PAs and to prioritize them according to biodiversity values and threats so as to support decision making and fund allocation processes.

It is great stuff: detailed, standardized descriptions of the importance of — and threats faced by — each protected area in Africa. I wonder if something similar will ever be done for agricultural biodiversity. An interesting first step might be to mash these results with those of the recent survey of crop wild relatives in protected areas. Unfortunately, the agrobiodiversity and protected areas communities hardly ever speak to each other.

Disease hotspots mapped

A letter in Nature this week looks at “Global trends in emerging infectious diseases.” ((Kate E. Jones, Nikkita G. Patel, Marc A. Levy, Adam Storeygard, Deborah Balk, John L. Gittleman & Peter Daszak. Nature 451, 990-993 (21 February 2008); doi:10.1038/nature06536.)) It includes some interesting maps, including these:

They show the global distribution of relative risk of an emerging infectious disease (EID) event caused by: (a) zoonotic pathogens from wildlife, (b) zoonotic pathogens from non-wildlife, (c) drug-resistant pathogens and (d) vector-borne pathogens. That’s based on climate, human population density and growth, and wildlife host species richness. Note in particular the map in the top right-hand corner: basically risk of zoonotic pathogens jumping to humans from livestock. Compare this livestock density ((FAO has more data on this.)):

Not a great match with density of domesticated animals. Maybe the correlation would be better with livestock diversity?
