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.
Mapping the World with Landsat
Speeding around the Earth at 16,800 mph (27,000 kph), two Landsat satellites are quietly, expertly watching and recording changes in Earth’s lands from space. They are gathering data for people to make maps–all kinds of wonderful maps–of our cities growing, rivers flooding, lava flowing from volcanic eruptions, forests expanding or shrinking, crops greening through the growing season, and even of evidence of pollution.
Vast Water Reserves Found in Drought-Prone Northern Kenya
Large underground water reserves have been found in Turkana, one of Kenya’s driest and poorest regions. The discoveries were made by the natural resources exploration firm, Radar Technologies International, during the course of a survey of groundwater conducted for the Kenyan Government on behalf of the UN. The aquifers were detected with the WATEX System, RTI’s state-of-the-art, space-based exploration technology.

Landsat can be an Impartial Arbitrator in Water Conflict Issues
Speaking at an important state-wide water summit in March, Nevada Governor Brian Sandoval lauded DRI’s METRIC program calling its Landsat satellite technology an important tool in monitoring water usage.
