Accelerated Human Population Growth at Protected Area Edges

Wittemyer, George, Elsen, Paul, Bean, William T., Burton, A. Coleman O., Brashares, Justin S.·2008·Science

Abstract

Protected areas (PAs) have long been criticized as creations of and for an elite few, where associated costs, but few benefits, are borne by marginalized rural communities. Contrary to predictions of this argument, we found that average human population growth rates on the borders of 306 PAs in 45 countries in Africa and Latin America were nearly double average rural growth, suggesting that PAs attract, rather than repel, human settlement. Higher population growth on PA edges is evident across ecoregions, countries, and continents and is correlated positively with international donor investment in national conservation programs and an index of park-related funding. These findings provide insight on the value of PAs for local people, but also highlight a looming threat to PA effectiveness and biodiversity conservation.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • As human populations adjacent to many protected areas grow rapidly, colonization and propagule pressures will increase.

    “However, as human populations adjacent to many protected areas are growing rapidly (Wittemyer et al., 2008), colonization and propagule pressures will increase.”

    From Scientists' warning on invasive alien species (2020) · cites this paper as Wittemyer et al., 2008

  • Previous studies suggest that both the rate of land-use change and the growth of human populations can be fastest near protected area boundaries.

    “Previous studies suggest that both the rate of landuse change and the growth of human populations can be fastest near protected area boundaries ( 13 -16 ), which accelerate the rate of edge degradation through increased livestock production, crop cultivation, and extraction of natural resources such as charcoal and bushmeat.”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
