Satellites key to addressing water scarcity

22 Mar 2019

Today is World Water Day, but with millions of people in Mozambique, Malawi and Zimbabwe struggling to cope in the aftermath of Cyclone Idai, the notion of water shortages may not be at the forefront of our minds right now. Even so, floods, like we see here, lead to real problems accessing clean water. Whether the problem is inundation or water scarcity, satellites can help monitor this precious resource.

The UN World Water Day underscores the importance of freshwater and promotes sustainable management. This year, the focus is on the UN Sustainable Development Goal 6 (SDG 6), which aims to ensure the availability and sustainable management of water for all by 2030.

With more than two billion people living without safe water and around four billion people suffering severe water scarcity for a least one month a year, achieving water for all is a huge challenge. And, coupled with a growing global population and climate change, it's likely to become even more challenging.
