Abstract

Accurate, up-to-date information on land cover and land-use is essential for strategic planning, sustainable resource management and environmental research. A land-cover database for South Africa, Swaziland and Lesotho, designed for use in a variety of regional modelling, monitoring and analytical endeavours, has been created. Database development involved (1) a stratification of natural land cover and human land-use, (2) a contextual classification of hardcopy multispectral data derived from Landsat Thematic Mapper (TM) imagery collected from 1994 to 1996, and (3) a stratified post-classification accuracy assessment using a large sample of field data. The resultantdatabase has yielded substantial information to characterize the landscapes of South Africa. The analysis uses data recorded by province, primary hydrological catchment and vegetation biome to explore the land-cover characteristics of South Africa, Swaziland and Lesotho. Aggregated results show that South Africa comprises the following general surface types: 5.8% forest and woodland; 0.3% forest; 17.6% thicket and bushland; 34.1% shrubland and low fynbos; 0.2% herbland; 21.3% grassland; 12.2% cultivated lands; 1.5% forest plantations; 0.4% waterbodies; 0.5% wetlands; 0.2% barren rock; 4.9% degraded lands; 1.1% urban/built-up lands; and 0.14% mines and quarries. The accuracy of the database ranges from 51% to 93%, depending on geographical area, with corresponding kappa index values from 35 to 88.
