World Environment Day 2024 focuses on land restoration, halting desertification and building drought resilience – areas where the International Atomic Energy Agency (IAEA) is already making a significant difference. The precision and power of nuclear science are helping countries meet their development challenges the world over. When it comes to drought resilience, nuclear science has a particularly helpful tool: isotope hydrology. This amazing science helps governments find and understand the source of their water supplies – so they can develop management systems to reduce the risks of conflict and build resilience to drought. This short film examines the case study of Kenya and the farmers and scientists working on drought resilience there. Watch the full version, including chapters on climate smart agriculture and plant evolution breeding and see how the IAEA is helping Kenyan experts get the food and water they need from a water-scarce land.
