Keeping Track of Food Production From Space

In the 1980s, scientists discovered that satellites could monitor plant growth by detecting chlorophyll. This led to the creation of GLAM, a tool for global crop health monitoring, which remains in use today. Technological advancements have since expanded these systems. In 2020, satellite data was crucial in assessing damage from a major windstorm in the Midwest, highlighting its role in preparing markets for crop shortages due to climate change. NASA's technology continues to support food security and market stability.
