Recent droughts in Africa and elsewhere in the world, from China to Peru, have serious implications for food security and grave consequences for local and international politics. The issues do not just concern the plight of African peoples, but also our global ecological future. Global climatic changes become manifest initially in regions that are marginal or unstable. Africa's Sahel zone is one of the most sensitive climatic regions in the world and the events that have gripped that region beginning in the 1970's were the first indicator of a significant shift in global climatic conditions. This work aims to bring archaeology with the domain on contemporary human affairs and to forge a new methodology for coping with environmental problems from an archaeological perspective. Using the later prehistory of Africa as a comparison, the utility of this methodological strategy in interpreting culture change and assessing long-term response to current, global climatic fluctuations is examined and understood.

Highlighting the importance to ecological studies of incorporating humans and their effects on ecosystems, leading experts from a variety of disciplines address a number of important issues, including: * the prominent role of humans in the function of ecosystems on Earth * why humans have been ignored in ecological studies * approaches taken by social scientists, historians, geographers, economists, and anthropologists in the study of human activities * the emergence of a new ecological paradigm accommodating human activities * methods for studying subtle human effects, and human- populated ecosystems * future research and training required to include humans effectively as components of ecological systems. Of interest to students and researchers in ecology, and to policy-makers and environmental managers. In addition, it makes social scientists aware of new opportunties for integrating their ideas with those of ecologists.
