Expert Advisory Group

Our Expert Advisory Group (EAG) gives us an independent perspective on our strategy, performance, and major decisions.

We are fortunate to have attracted independent experts from across the world and a wide range of disciplines to join the EAG, whose expertise and advice we can draw on to help us:

  • Ensure our analysis, recommendations and policy proposals are accurate and based on best available knowledge
  • Avoid advancing policies or ideas with unanticipated adverse side-effects
  • Assess the viability of and rigorously evaluate recommendations made by ourselves, supporters, the public and other organisations
  • Understand and integrate social, cultural and ethical considerations across our work.

We regret that we are unable to provide contact details for or forward correspondence to members of the EAG.

Alisha lectures internationally on population and development in the Sahel. She is a research fellow for Project Drawdown, and helped analyse the potential contribution of family planning and girls’ education for reducing greenhouse gas emissions. Previously, she worked to improve women’s access to misoprostol, a generic, essential medicine.

William Rees

William Rees is a population ecologist, ecological economist, Professor Emeritus and former Director of the University of British Columbia’s School of Community and Regional Planning. He is a founding member and former President of the Canadian Society for Ecological Economics; a founding Director of the One Earth Initiative; and a Fellow of the Post-Carbon Institute. Prof Rees’ research focuses on the biophysical requirements for sustainability and the policy implications of global ecological trends. He is perhaps best known as the originator and co-developer with his graduate students, of ‘ecological footprint analysis’. EFA shows that the human enterprise is already in ecological ‘overshoot’ and that we would need 4.4 Earth-like planets to support just the present world population at Canadian material standards. Such findings led to a special focus on cities as particularly vulnerable components of the human ecosystem and on psycho-cognitive barriers to ecologically rational behaviour and policy. Prof Rees has authored hundreds of peer-reviewed and popular articles on these and related topics.

William Ryerson

Ryerson is Founder and President of Population Media Center (PMC), an organization that strives to improve the health and wellbeing of people around the world through the use of entertainment-education strategies.
