Global Methodology for Mapping Human Impacts on the Biosphere



Liaise ownership:



GLOBIO was created to explore the impact of environmental change on biodiversity. The model draws on information from current scientific studies on environmental impacts and relates this to infrastructure development to create different scenarios up to 2050.
The model is mainly used for:
• analysing current levels and future developments of land areas that are directly urbanised;
• analysing current levels and future developments of land areas that are converted for agriculture or infrastructure, or are fragmented and under conversion;
• analysing current levels and future developments of land areas that are still relatively intact ecosystems;
• analysing the impacts of land-use policy options and scenarios with different social, demographic or economic assumptions.
The model’s parameters are estimated using historical data sets and these drive future trends. The model uses the assumption that in most areas, infrastructure occurs in clusters, which expand gradually from the original point, with the highest density present in urban areas.

Input variables:

Data Source(s):

Cartographic data: DCW (VMAP* level 0) - The DCW is a digital mapping database based on the United States Operational Navigational Chart Series (ONC), scale 1:1,000,000. The data were collected between 1968 and 1989.
Classification data for ecosystems: Global Land Cover Characterization (GLCC) - This is a global map dataset, created from satellite imagery.

* VMAP (vector map) is a vector-based collection of geographic information system data about Earth. Level 0 is global coverage at low resolution; level 1 is global coverage at medium resolution.

Output variables:

Land use and land-use change:<br />
Land cover, Intensity of agriculture, Land degradation<br />
Fragmentation: <br />
Infrastructure, dams, patch size of natural areas<br />
Climate change: Temperature and precipitation<br />
Pollution: Nitrogen deposition<br />
Acidification, Polychlorinated Biphenyls, Oil spills<br />
Water extraction: Quantity of water used for irrigated land<br />
(Over)exploitation: Forestry,<br />
Grazing, Fishery, Hunting and collection
