ANDREW GORDON

Andrew Gordon is a faculty member in the School of Environmental Sciences at the University of Guelph and director of the university's Agroforestry Research and Development Program.  The University of Guelph is consistently ranked as a top comprehensive university with innovative research-intensive programs.  Its academic achievements include the first scientific validation of water on Mars, codevelopment of the Alpha Particle X-ray Spectrometer for NASA and the Barcode of Life project for species identification.

Dr. Gordon's research interests lie in the investigation of ecosystem-level processes in both agricultural and temperate/boreal forest systems.  He recently led a six-university collaboration as part of Canada's contribution to the Global Research Alliance on Agricultural Greenhouse Gases to mitigate GHG emissions in the agricultural sector, a 46-country alliance.  He has been involved in international educational initiatives in Nepal, Argentina, Bolivia, and Vietnam, and has directed a major CIDA-sponsored project in Ghana to alleviate poverty through agroforestry practices, and is the author/co-author of over 150 research publications.

JAMES HANSEN

James Hansen, one of the world’s leading climate scientists, has authored dozens of peer-reviewed scientific papers on climate science.  After nearly a half century of research in planetary and climate science for NASA’s Goddard Institute for Space Studies (GISS) – including landmark testimony to the US Congress in 1988 urging acknowledgment of human-caused global warming – Dr. Hansen now leads the Climate Science, Awareness and Solutions program at the Columbia University Earth Institute. His pioneering research has shaped much of our current understanding of human-caused climate change.

Dr. Hansen is also an adjunct professor in the Department of Earth and Environmental Sciences at Columbia University and the author of the critically acclaimed Storms of My Grandchildren.  

Steven Higgins

Steven Higgins is a plant ecologist and professor of botany at the University of Otago, New Zealand, whose research looks at the processes that influence the distribution and dynamics of plant species and vegetation.  His work includes a study published in the journal Nature Climate Change that documents widespread and substantial change in global patterns of vegetation activity over recent decades, changes likely to have significant impact on ecosystem stability, carbon and energy exchange between land surface and the atmosphere and agricultural practices.  

Dr. Higgins has a long history of research in savanna ecosystem dynamics and carbon sequestration, including field work in Kruger Park, RSA.  Since moving to New Zealand, he has been setting up research projects related to the evolution of species and functional diversity.  His work on savannas has been motivated by a curiosity to understand the conditions under which grasses and trees coexist, but applications of this research include defining principles for the sustainable management of extensive rangelands and how savannas, grasslands and forests respond to elevated atmospheric carbon dioxide. Steve’s research areas include biogeography, conservation biology and ecological economics.

Pushker Kharecha

Pushker Kharecha is a climate scientist at NASA GISS and the Columbia University Earth Institute. His research focuses on the human dimensions of the global carbon cycle, including mitigation of the impacts of fossil fuel burning and land use.  He has served as a co-lead author at the United Nations Environment Programme and has led and co-authored high-impact peer-reviewed scientific papers with Dr. James Hansen.

Dr. Kharecha holds a PhD in geosciences and astrobiology from Penn State University.

Roger Leakey

Roger Leakey is a plant physiologist and tree biologist with a distinguished career in research integrating trees as a valuable resource in agriculture.  He is a member of the renowned Leakey family of archeologists, paleontologists and environmentalists. His concept of tree domestication for agroforestry was implemented by the World Agroforestry Center as a global initiative in 1994, where he led significant research projects on the domestication of culturally important trees in agriculture with more than 10,000 farmers.  His acclaimed book Living with the Trees of Life – Towards the Transformation of Tropical Agriculture has been called a guiding star for the rebirth of tropical agriculture.

Dr. Leakey is a former director of research at the International Centre for Research in Agroforestry (ICRAF) and former professor of agroecology and sustainable development at James Cook University in Cairns, Australia.  He was a coordinating lead author in the International Assessment of Agricultural Science and Technology for Development (IAASTD), a three-year intergovernmental process involving over 400 scientists sponsored by the World Bank and relevant UN agencies.  He is a Fellow of the Royal Geographical Society.

Richard Oppenlander

Author of Comfortably Unaware: Global Depletion and Food Choice Responsibility, Richard Oppenlander is a sustainability consultant and researcher who has studied the relationships between global resource depletion, choices of food and how current demands for animals and fish have become a dominant influence on earth’s ecological webs.  Dr. Oppenlander has been a keynote speaker at universities, colleges and corporations on food choice responsibility and how our livestock-fishing vacuum is directly tied to poverty, the erosion of life-sustaining resources, and critical losses of biodiversity. His most recent book, Food Choice and Sustainability, is described as an impeccably documented and vital wakeup call.

CHARLIE SHACKLETON

Charlie Shackleton is an interdisciplinary scientist and professor and DST/NRF research chair in the Department of Environmental Science, Rhodes University, South Africa. He has published widely on issues relating to rural livelihoods in Southern Africa, particularly in relation to the use of and trade in wild natural resources, as well as the ecology and sustainable use of such resources.  He has applied similar concepts and methods to examine the supply and demand for wild natural resources in urban settings. He guides postgraduate students in several Southern and West African countries and collaborates in research projects and networks internationally. Dr. Shackleton holds a PhD from the University of the Witwatersrand (South Africa).

Gordon Studebaker

Gordon has created and managed competitiveness-enhancing economic, enterprise and agricultural initiatives in 32 countries and 60 US cities, including former socialist and disaster/conflict-disrupted economies.  He has advised and positioned governments, small and mediumagricultural enterprises and communities on country, market and area competitiveness.

Gordon is skilled in reducing blockages to advances in agro-enterprise and in identifying and exploiting wealth creation gaps.  His achievements include the building of agricultural opportunities across Iraq; building of a portfolio of more than 75 enterprise and agriculture opportunities across Aceh exploiting gaps in supply and value chains to advance tens of thousands of Acehnese; organizing and leading the largest business-agricultural development, investment-attraction and advocacy mission to a foreign country in Guyana’s history; and development of US Treasury initiatives that moved $6 billion into financial institutions serving poor areas for economic development in US inner cities.

paul turner

Paul Turner is the chair of Ecology and Evolutionary Biology at Yale University, and a faculty member in the Graduate Program in Microbiology at Yale University School of Medicine.  At Yale, Dr. Turner has served as director of graduate studies in the Department of Ecology and Evolutionary Biology, and on the Graduate School Executive Committee, Howard Hughes Medical Institute Undergraduate Program Steering Committee, and university Budget Committee.  He has also been a visiting scholar at University of California San Diego, and Visiting Faculty Fellow in the Josephine Bay Paul Center for Comparative Molecular Biology and Evolution at Marine Biological Laboratory, Woods Hole, MA.

Dr. Turner is involved in worldwide research and training programs in the rapidly growing field of evolutionary medicine, virus ecology and evolution, host parasite interactions and the evolution of infectious disease.  The evolutionary approach has driven important advances in our understanding of the increasing spectrum of autoimmune disease and infectious triggers in diseases like HIV/AIDS and diseases caused by other RNA viruses, including Ebola hemorrhagic fever, SARS, West Nile fever, polio and measles.
