Landsat’s Role in Managing Water Resources
Water is essential for life. A third of Earth’s populace has unreliable access to clean water. With current population growth and environmental trends, the U.N. Environmental Program estimates that 1.8 billion people will face water scarcity by 2025. Water means survival for people and other species we rely upon to thrive, making proper stewardship of our water resources vital. Good decisions require good data. Since 1972 the Landsat series of satellites has been providing such data. Landsat-based decisions on how to manage limited water resources have impacted millions of people worldwide. From finding water for refugees in arid nations to reducing pollution in our national waterways, Landsat enables decisions that directly help people.

Landsat Sees Dr. Beach’s Top 10 Beaches of 2021
For over 30 years, Dr. Beach, aka Dr. Stephen Leatherman, a professor and coast geomorphologist at Florida International University, has created a Top 10 Beach list based on criteria including water and sand quality, safety, and management. You can find his 2021 picks here and see how Landsat views them as well.
