Joost BROUWER "Are the most valuable resources in drylands areas wetlands?"

  1. 1. Is this good or is this bad?A landscape severely eroded after the drought of 1974 brokein 1975 with a big rainstorm washing away topsoil and seeds.
  2. 2. The run-off from that eroded area CREATED this wetland of1500 hectares in central Niger, that did not exist before 1975and is now heavily used by local people.
  3. 3. Point 0:Land degradation and desertificationare not necessarily all bad.Look at the whole system beforeconsidering change.
  4. 4. Are the most valuable resources indryland areas isolated wetlands?Joost Brouwer PhDBrouwer Envir.&Agric. ConsultancyThe Netherlandsimages Joost Brouwer, Hans Hut, Ulf Liedén, Leen SmitsIUCNCommission on Ecosystem Management
  5. 5. The Sahel zone is the yellow zone that runs East-West forabout 7.000 km along the southern edge of the Sahara.

  20. 20. Population growth Niger >3.2% per annum,a doubling every 20 years [a neutral statement of fact]
  21. 21. More people use more resources: stumps remain where15 years ago there was an Acacia nilotica forest

  24. 24. Point 4(data 1993-1994 vs 2006-2008, in paper):Isolated wetlands in the Sahel are undergoingrapid change/degradation due to:- population growth- migration- socio-economic changes (e.g. in diet)- land use change in catchments
  25. 25. Summary0. DLDD is not only bad: look at the whole system.(Ecosystem Approach; SYSTANAL in English, French, Arabic)In the Sahel:1. There are thousands of isolated wetlands.2. These wetlands are very valuable to man & biodiversity.3. The wetlands allow use of associated drylands, and v.v..4. Wetland quality is greatly threatened for all uses.5. PINReM of the wetlands is urgently needed.(Participatory Integrated Natural Resource Management)What about the isolated wetlands in your own country?
  26. 26. ImplicationsFor research:Inventory of wetlands and valuation of their servicesFor practice:Strive for PINReM with all stakeholders, looking at wholesystemFor policy:Develop and implementNational Wetland Programmesfor sustainable wetland use and conservationThe UNCCD should do this in cooperation with Ramsar,CBD, UNFCC, CMS, AEWA and their parties:
