The second phase of the project of formulation of erosion combating programmes in the pilot watersheds in the Maghreb countries was launched in a workshop organised on the subject in Tunis on June 30 – July 2, 2004. The workshop, organised in collaboration with the Directorate of Soils of the Tunisian Ministry of Agriculture and Water Resources, was attended by the members of the national teams of the three countries involved in this second phase, as well as 10-odd experts from interested Tunisian institutions. The main objective of the workshop was to train the national teams on the formulation of “technological packages” (preventive, protective and remedial measures) for erosion management in the watersheds mapped in the previous phase (valley of Bas Isser in Algeria, Oued Beni Boufrah in Morocco, Oued Ermel in Tunisia).
