Dr. Jeffrey Wall specializes in innovating and adapting methods and theories which bring the environmental and plant values of distinct cultures and traditions into meaningful conversation with each other. He has conducted impactful research on threatened culturally significant landscapes in numerous countries in the Near East, Central Asia and North America. A major threat to such cultural landscapes is rural exodus, a widespread demographic trend which is the focus of his E.U.-Sponsored research program, "Homeland No More: Seeking the Biocultural Origins of Rural Exodus in the Mediterranean Basin."
