In 2021, as the world comes together to address the critical challenges posed by a rapidly changing and increasingly variable climate, this year's posts will highlight the links between climate and food security, the unique light that data from Earth-observing satellites can shed on these relationships and the role that each one of us has to play in using this knowledge to support the well-being of people and the planet.

Earth observations data are key inputs into the kinds of analyses and decision-making processes that are critical to promoting food and water security and resilience to recurrent crisis. Because Earth observations provide global, frequent and detailed information about rainfall, temperature, soil, crops, water, forest cover and land use, they help us obtain a better understanding of the conditions in the places where we work, improve targeting of programs to populations in need and conduct evidence-based assessments of whether those programs had their intended benefit.
