  • 2. 2 Degradation: What do we know...? A lot!
  • 3. 3 And much is being done about it... € $ ¥ £ € $ ¥ £ € $ ¥ £ € $ ¥ £ € $ ¥ £ € $ € $ ¥

  • 8. 8 Land Use System (LUS) Type Area trend Intensity trend Mapping Land Degradation and SLM • Method jointly revised with LADA and DESIRE • More emphasis on impact on Ecosystem Services, direct and indirect causes • Being tested in 6 LADA pilot countries (national level) • Applied in 18 DESIRE study sites (local level) • Additionally tested in Tajikistan and Switzerland (village level) Mapping Unit
  • 9. 9 Degradation / Mapping unit SLM / Mapping unit Type Name / Group / Measure Extent (area) Extent (area) Degree Effectiveness Impact on ecosystem services (type and level) Impact on ecosystem services (type and level) Direct causes Indirect causes Degradation addressed Recommendation Mapping Degradation and Conservation

  • 19. 19 Some challenges! • How to visualise “dominant” degradation (or conservation) types in case of combinations or multiple types / unit: Mapping Unit ID a) Type b) Extent c) Degree d) Rate i ii iii 13 Wt Wg Wo 30 2 0 13 Ha Hg Hq 70 3 -99 14 Wt Wg Wo 30 2 0 14 Ha Hg Hq 60 3 0 15 Ha Hg Hq 60 3 0 15 Wt Wg Wo 30 2 0 • Show each combination? ( too many legend units) • Show dominant types only ( what is dominant: highest degree, highest extent,…) • …?
