 How can nuclear science promote sustainable development? This farmer has livestock and a steady income. This fruit grower has pest-free crops. These people have access to clean water. And this patient is receiving safe healthcare. These people are just a few of the millions around the world who have benefited from the International Atomic Energy Agency's technical cooperation program. The program is the IAEA's main channel to deliver assistance to its member states. It enables the safe use of nuclear science and technology to drive sustainable development. The technical cooperation program dates back to 1957, to a time when the IAEA was founded as the Atoms for Peace Agency. At any given moment there are over 1200 technical cooperation projects in around 145 countries. In the areas of health, food, energy, water, and the environment, the IAEA responds to the world's evolving needs. It does this by building capacity and transferring knowledge and expertise. Through the technical cooperation program, essential equipment is procured, installed, and properly maintained. The tools needed for field research and project implementation are provided as well. The IAEA responds quickly to the needs of its member states. During the first months of the COVID-19 pandemic, the agency delivered support and equipment for the rapid detection of the virus to over 100 countries. The technical cooperation program organizes trainings at the IAEA's laboratories in Austria and Monaco. And at partner institutes around the world. With the right training, scientists, technicians, and health professionals return home to put their enhanced skills to work. Isotope hydrology is used to manage freshwater supplies. Marine pollution is being monitored with nuclear science. Precious works of art are being restored with radiation techniques. Nuclear medicine treats and manages illnesses. And future radiation therapists are being trained. The IAEA forms networks of laboratories and nuclear institutes to share information and resources. It brings people together through the technical cooperation program to discuss progress and ways to enhance cooperation. Science and technology are central to sustainable development. The IAEA provides the necessary infrastructure for the effective use of nuclear techniques and the safe management of radioactive materials. Providing the right tools and skills, investing in people, and forming networks. This all sets the wheels in motion for long-term and far-reaching impact. Since the 50s, the IAEA has made a vast contribution to social and economic development. People have better health and incomes, more food and cleaner water. There's greater access to low-carbon energy and industries are more efficient. Countries have capabilities and skills to use nuclear technology for peaceful purposes. As for the future, the technical cooperation program is expected to grow even stronger. And it will continue to be the IAEA's Driving Force for Development.
