My latest book reveals how spiritual ideas nurture sustainable landscapes in a time of ecological crisis. As one of the fastest expanding economies in the world, Ethiopia faces environmental pressures. In Amhara province, the last native forests surround church buildings and have been protected for centuries as miniature Gardens of Eden.

The photographic essay about these church forests has been published in part in Nature, Geo France and National Geographic as well as being awarded a Sony World Photography Award in the Landscape category. The work has also been exhibited in Los Angeles, New York and Edinburgh. The book brings together the full story and unpublished photographs, with a specially commissioned essay by Professor Mark Stoll on the spiritual roots of modern environmentalism, along with a foreword by church forest expert Dr Alemayehu Wassie Eshete.

The publication of this book has supported the restoration of the Ethiopian landscape with the planting of a thousand trees in the upper Blue Nile river catchment area near Lake Tana. This is a collaboration of the local community, local scientists and the organisation Plant with Purpose.

Also available are a Special Edition book, Print sets to protect nature, Prints to plant a forest and book bundles.
