Professor Emeritus John Boardman

John has worked for over 20 years in the Karoo, South Africa on degradation by overgrazing and its impacts. He continues to work on soil erosion in southern England including recent work on the impact of maize cultivation on flooding in Devon (with the EA). A new project on Sunken Lanes in England is planned with Natural England.

As former Director of the MSc in Environmental Change and Management, John continues to teach on the course and to lead field trips.
