We’re joined this week by Dr. Mark Tester, Professor of plant science and associate director at the Center for Desert Agriculture at the King Abdullah University of Science & Technology. He’s also the co-founder of Red Sea in Saudi Arabia, where they focus on reducing the water footprint to make the food systems more sustainable. Dr. Tester explains the challenges of the food-water-energy nexus, some of the impact of his work with Red Sea, and his advice to the young entrepreneurs who want to explore innovations in sustainability.
