This third edition of the World Atlas of Desertification focuses on land degradation and global environmental change under five major subject headings:Global Patterns of Human Domination. Highlighting the role of Homo sapiens as the major driving force of global environmental change;Feeding a Growing Global Population. The ability to feed 10-12 billion humans by the end of the century is one of the great challenges facing humanity, creating enormous burdens on the land;Limits to Sustainability. The Brundtland Commission defined sustainable development as ?development which meets the needs of the present, without compromising the ability of future generations to meet their own needs?. There are numerous obstacles that must be overcome to achieve this goal;Converge of Evidence. Many of the anthropogenic-induced environmental changes can be measured and their combined effect are indicative of the multiple stresses humans exert on the land. WAD3 draws on this complexity by adopting the concept that evidence or signals from multiple sources may ?converge?, thus leading to the development of testable hypotheses and/or conclusions that are supported by data. Convergence of evidence maps replace ?maps of desertification? as per WAD1-WAD2; and Solutions. Potential solutions to land degradation need to be identified and implemented within the context of local social, economic, and political conditionsTwenty years have passed since the last atlas of desertification was published. Within that short period enormous global changes have taken place in terms of human expansion and the impact that had on the environment. Equally significant progress has been made in understanding the fundamentalsof human-environment interactions.This has been made possible, in part, by the massive increase >and growth in the accessibility of global andWAD3 thus begins at a very different place than WAD2 in terms of scientific information and understanding. That said, we are also confronted by the rapidly growing appreciationof the complexity of the land degradation phenomenon and all the human factors that both drive it and are derived from it. As a consequence, rather than attempting to produce a comprehensiveglobal model that cannot deliver useful local or regional information, WAD3 offers an approach that accommodates and embraces these complexities and is intended to provide an information framework from which to pursue solutions that fit specific local situations.
