Can human-induced land degradation be distinguished from the effects of rainfall variability? A case study in South Africa

“…Average NPP-RUE, 1991-92 NPP-RUE and 1997-98 to 1999-2000. Note that the NPP includes both above-and below-ground production.…”

“…5). The average NPP-RUE (1981-82 to 1999-2000 was lowest in the mountains of The number of pixels varied between degraded and non-degraded areas of each LCU. Lesotho and the escarpment in the Mpumalanga and Limpopo provinces, probably because although these areas experience high rainfall, there is extensive surface run-off due to steep topography (Fig.…”

“…4-6). The RUE trend map showed negative trends where very high rainfall towards the end of the time-series caused low RUE values despite exceptionally high NPP values (1998( -99 and 1999( -2000. It is clear that simply calculating the annual ratio of NPP or SNDVI and rainfall does not remove the effects of rainfall variability on vegetation production for individual years and that inter-annual comparisons of RUE maps cannot be used to monitor land degradation as suggested elsewhere (Holm et al, 2003;Symeonakis and Drake, 2004).…”
