Bob Evans

In the 1960s Dr Robert (Bob) Evans counted sheep for 2 years in the Peak District: There were too many of them and they created bare soil and caused erosion. Bob came to Cambridge in late 1968 to research the use of remote sensing techniques for mapping soils. So started a lifetime of monitoring soil erosion in the UK. Much of the work on erosion in Britain was initiated by a short paper of published by Bob in 1971. In the mid-1980s he organised a scheme monitoring water erosion of arable land in 17 localities in lowland England and Wales. Because, uniquely, there has been much monitoring of erosion in farmers’ fields in Britain we can compare that information with modelled information and have discovered that models overstate erosion. 

Bob has been an independent consultant since the late 1980s, most of that time being also a Research or Visiting Fellow in Cambridge Universities. He has worked with government departments, the Environment Agency, a major NGO, companies, farmers and the NFU and on university Research contracts, as well as being an expert witness in court. His work in the uplands helped bring about changes in national grazing policy and he was an advisor to the Royal Commission on Environmental Pollution when it produced its report on Sustainable Use of Soil in 1996. Bob now considers that soil erosion, although a problem over the long-term (in causing the loss of a resource) and short-term (causing pollution of water courses by sediment), nutrients and pesticides transported from the land in runoff is the more pressing issue.

Bradley Hiller

Dr Bradley Hiller has been a Visiting Fellow at GSI since October 2014. Bradley was part of the ‘UK-US Taskforce on Resilience of the Agrifood System to Extreme Weather Events’, where he and Aled Jones coordinated the qualitative components of the Taskforce activities and co-authored multiple outputs, which have purportedly been used globally. Bradley also worked with Michael Green to co-author a multi-university study of innovative and integrated mobile early warning systems for extreme events in developing urban areas.

Further to his role at GSI, Bradley is currently based in Washington, D.C., where he works as a Lead Consultant for the World Bank on issues related to water, climate change and rural and social development. Bradley also works as a Specialist Climate Change Consultant for the Asian Development Bank (based in the Philippines) and as an Associate Consultant at the Cambridge Institute for Sustainability Leadership on corporate sustainability (based in the UK). Bradley has PhD and Master’s degrees in sustainable development from the University of Cambridge and undergraduate degrees in Environmental Engineering and Environmental Science from his native Australia. He has worked in seventeen countries, including one year in Mongolia.

Bradley is passionate about helping to alleviate poverty and promoting sustainable development principles. In his recreational time, he enjoys sports, (low-carbon) travel and exploring the potential of business to help solve social challenges.
