Landsat’s Critical Role in Water Management
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.
Kustas’ research informed the new OpenET app that uses Landsat thermal data as a key data input.
NASA will hold a virtual media briefing at 1:30 p.m. EDT Thursday, Oct. 21, to share a powerful, new, web-based platform to help those who rely on water resources across the drought-stricken western U.S.
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.
In Micronesia, the nation of Palau is building sustainable aquaculture farms in the ocean with the help of satellites.
‘Green tides’ of algae have wreaked havoc across the coastlines of Brittany, France, for half a century due to high levels of agricultural runoff. With efforts to reduce these underway, a new technique using over three decades of satellite images highlights the extent of the continuing problem.
