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.

Early Detection of Algae ‘Blooms’ by Satellite Yields Healthcare Savings
The use of satellite data by environmental managers tracking harmful algal bloom outbreaks along lakefronts and coasts can result in earlier detections that yield significant savings on healthcare, lost work hours and other economic costs.

Meet Dr. David Lagomasino
Coastal ecosystems are some of Earth’s most biologically diverse environments, especially coastal mangrove forests. Dr. Lagomasino uses Earth observing data to study these vital biomes.
