The African Group of the Third Conference of the Parties to the United Nations Convention to Combat Desertification (UNCCD) expressed interest in developing planning and management guidance for extractive industries in arid and semi-arid lands. This interest was reiterated by the members of IUCN at the second IUCN World Conservation Congress in Amman, Jordan, in October 2000. Members approved a resolution calling on the IUCN Secretariat to prepare and adopt guidelines for oil, gas and mineral exploration and exploitation in arid and semi-arid zones (Amman Resolution 2.57). IUCN, with the generous support of the U.S. Department of State, commissioned this publication through its West Africa Regional Office (BRAO) in Ouagadougou, Burkina Faso. Peter-John Meynell, Ruth Golombok and Petrina Rowcroft (Scott Wilson Resource Consultants) developed the initial draft, and Christopher J. Morry (IUCN Canada) organised the workshop where the second draft was discussed. Special thanks go to Ibrahim Thiaw (IUCN BRAO), one of the initiators of the project, who provided competent guidance on drafting this document. Stephen R. Edwards made major contributions to the structure and content. The draft version was developed in close collaboration with the Secretariat of the UNCCD in Bonn, Germany, through the kind assistance of Grégoire de Kalbermatten.
