We cannot exist without water. It is intrinsic to our survival and healthy ecosystems. That being said, water covers 70% of our planet, and it is easy to think that it will always be plentiful.
However, we are already facing challenges posed by water scarcity. Overpopulation and environmental challenges make water an even more precious asset. Water scarcity already affects every continent and nearly 20% of the world’s population. According to UN estimates, by 2025 nearly 1.8 billion people will live in areas with absolute water scarcity, and two-thirds of the world's population could be living under water stressed conditions. This indirectly influences the rest of the planet’s inhabitants both economically and environmentally.
This brings about an urgent need to efficiently govern and manage sources of water and to find ways to develop alternative sources of usable water, such as harvesting water. Ensuring the availability and sustainable management of clean water for all is one of the UN sustainable development goals. This is where digital technology can help and can improve the accessibility, safety, and usability of water resources. Such digital technologies are known as smart water or smart water grids, the Internet of water, and smart water management.
