  1. Africaoverview of the GLC2000 activities Philippe Mayaux & Michel Massart Institute for Environment and Sustainability, EC Joint Research Centre, Italy

  2. The overall context • 30,000,000 km2 • From dry deserts to tropical rain forests • Evergreen (forests, deserts) and seasonal (savannahs, grasslands) ecosystems • Permanent clouds in equatorial regions • Isolated continent Þ no overlap with other windows • 1 continental window (baseline map) + regional windows (improvements)

  3. Monthly max NDVI and min NDWI August – April - January

  4. The Africa window

  5. Some details

  6. IGBP DIS-Cover University of Maryland GLC 2000 VGT colour composite Global land-cover maps

  7. The locust window FAO / JRC

  8. The CILSS window • Centre AGRHYMET (Niger) and Université Catholique de Louvain (B) • Seasonality • Focus on validation techniques • 11 Sahelian countries • Centre de Suivi Ecologique (Senegal) involved in the validation process

  9. The Central Africa window • JRC (M. Massart) • Focus on rain forests • Cloud-cover (in coastal part) • Mosaic of single-date classifications in evergreen regions

  10. The Great Lakes window • Université Catholique de Louvain and Musée Royal d’Afrique Centrale (B) • Important region in terms of biodiversity (Albertine Rift) • Rain forests, miombo woodlands, grasslands, swamps, agriculture • Topography, cloud cover

  11. Eastern Africa • FAO-AFRICOVER • Validation • LCCS

  12. The Southern Africa window • Instituto Superior de Agronomia and Tropical Research Institute (Lisbon) • From miombo woodlands to Namibia deserts, seasonality • New composition techniques (image of May 2000) • Classification is coming • CSIR involved in the validation process

  13. Madagascar • UNEP – GRID • Validation

  14. The situation
