At Washington State University (WSU), archaeologists have developed computer simulations of the interactions between ancestral peoples in the American Southwest and their environment.

In 2001, WSU professor Tim Kohler launched the Village Ecodynamics Project to simulate how Pueblo Indian families likely would have responded to changes in specific variables such as precipitation, population size, and resource depletion, by having virtual Pueblo Indian families live on computer-generated and geographically accurate landscapes. By comparing the results of agent-based models against actual archaeological evidence, anthropologists can identify past conditions and circumstances that led different civilizations around the world into periods of growth and decline.

The WSU team describes the simulations as similar to a video game in that the virtual agents will play things out to the logical conclusion based on their parameters and rules. The technology could help modern communities identify new crops and other adaptive strategies when facing environmental challenges.

"Our hope is that combining traditional archaeology fieldwork with data-driven modeling techniques will help us more knowledgeably manage our numbers, our ecosystem interactions, and avoid past errors regarding climate change," Kohler says.
