The role of water for food and nutrition security was the central theme of a three-day course held at the Food and Agriculture Organization (FAO) headquarters in Rome. Organized by the World Food System Center, as part of a lecture on food security, the course brought together agricultural and environmental science students from ETH Zurich for an interactive learning experience.
Tackling an underestimated greenhouse gas with low-cost sensors
World food system

An innovative project is underway to equip farmers with low-power, cost-effective sensors designed to measure nitrous oxide emissions directly in their fields. This technology offers a promising route towards a more sustainable agriculture by enabling farmers to optimize fertilization and mitigate nitrous oxide emissions.
