AVHRR NDVI data, 1 km2 resolution, NOAA satellite series, 1985-2003 |
1985-2003 |
Seasonal total NDVI gives the long-term vegetation production of degraded and non-degraded rangelands and the trends in production per unit rainfall. |
| Wessels (2011) |
MODIS satellite data 2000-2005 |
2000-2005 |
Supplementary five-year NDVI record used alongside AVHRR to compare degraded and non-degraded areas. |
| Wessels (2011) |
National Land Cover map (NLC) 1995-96, from single-date Landsat TM imagery |
1995-96 |
Supplies the mapped 'degraded' classes (4.8% of the country, mostly in communal areas), which serve as the degraded study areas compared against non-degraded neighbours. |
