Dr. Greg Barron-Gafford is a Biogeographer and has largely been based in the drylands of the world. He has worked for the last 18 years in the southwestern US studying Earth System science, plant ecology, and the impacts of climate and land use change. Since 2011, he has been building the field of 'agrivoltaics' - the concept of collocating agriculture and photovoltaics (renewable energy from solar panels). Professor Barron-Gafford and his team began working in southern Arizona with the Community & School Garden Program to study the benefits across the food-energy-water nexus, and over the years have developed a national and international program connecting with researchers in Colorado and Oregon (USA), and in Africa and the Middle East. Helping develop science-based solutions to help people adapt to the increasing pressures that come from a changing climate being a personal and professional goal.
