Description:

Abstract:

Rates of loss of natural land cover for the world’s biomes and realms are measured using the HYDE Database of global land use (URL: <http://arch.rivm.nl/env/int/hyde/>). These datasets use information on historical population patterns and agriculture statistics to estimate habitat conversion between 1950 and 1990, based on maps of 0.5-degree resolution for the WWF Terrestrial Ecosystems biomes and realms.

Purpose:

Illustrate the rate of habitat loss as a result of human population growth and related human activities of cultivation (crops and livestock)

Data_Quality_Information:

Attribute_Accuracy:

Attribute_Accuracy_Report:

Estimates of the agricultural land area in 1950 were based on historical statistics. The accuracy depends on the source (see Klein Goldewijk, 2001). The agricultural land area in 1990 is based in FAO statistics.

Logical_Consistency_Report:

Prior to the analyses WWF classifications of biomes and realms were gridded into 0.5 degree grid map, in order to fit it with the data from HYDE.

Completeness_Report:

Allocation of grazed and agricultural land are based on well descibed rules and assumption (see Klein Goldewijk, K., 2001: Estimating global land use change over the past 300 years: the HYDE database. Global Biogeochemical Cycles, 15, 417-434)
