In recent years environmental archaeologists have emphasized evidence for human-caused degradation, and attention has been focused on the role of our discipline in debates over contemporary socioenvironmental problems. In a recent American Antiquity forum, van der Leeuw and Redman (2002) argue that current environmental research would benefit from an archaeological perspective on these problems, and that our discipline would benefit from more active engagement in the larger debate. I present research supporting the claim that archaeology has unique and compelling insights to offer socio-natural studies. I make arguments based on spatial statistical and GIS analyses of past land use in the Wadi al-Hasa, west-central Jordan, that environmental degradation in the form of soil erosion has been a problem for agropastoralists in that region for several millennia. Furthermore, I argue that an archaeological perspective on long-term patterns of land use provides information at a scale and resolution that makes it highly suitable for studies of human-environment dynamics. Archaeology's unique data and perspective create an opportunity to contribute in a more explicit manner to the study of contemporary environmental issues that currently lack long-term focus at a scale and resolution that is meaningful to humans.
