  1. Estimating the Carbon Cycle of South Africa with BETHY/DLRAn Assessment Approach for Land DegradationMarkus Niklaus, Markus Tum, Kurt Günther, German Aerospace Center (DLR) EGU General Assembly 2010, Vienna

  2. Envisat MERIS, ESA 2004 Area of interest: South Africa GLC2000, JRC

  3. Data base Methodological development Results Land Cover Classification (GLC 2000, MODIS VCF) BETHY/DLR Biosphere Energy TransferHydrology Model Leaf Area Index (VEGETATION) Net-Primary-Production(NPP) Net-Ecosystem-Production(NEP) Photosynthesis Stomatal conductivity Light use efficiency Water balance Evapotranspiration Soil respiration Soil Types (FAO) Relief/Geopotential Meteorological Data (ECMWF) The Vegetation Model BETHY/DLR further information: Poster EGU2010-3945 at BG86

  4. Meteorological Input Data(Scrubland)

  5. Results: NPP Map for South Africa 2001 200 0 National NPP-Sum for the year 2001 130 MtC

  6. Results: Model Output for Scrubland-Pixel Gross- and Net Primary Productivity (GPP/NPP) Actual and potential Evapotranspiration (ATP/PTP)

  7. Validation / Comparison Validation with annual statistics about biomass stocks in semi-arid scrublands Validation Approach: EGU2010-4228 by Markus Tum at XL17 Comparison with products derived from satellite data MODIS GPP and NPP C-Fix VEGETATION Spot 5, CNES
