Water is essential for human existence and life in general. This inorganic, transparent, tasteless, odorless, and nearly colorless chemical substance is the main constituent of Earth’s hydrosphere and the fluids of all known living organisms. The origin of water on Earth is the subject of a body of research in planetary science, astronomy, and astrobiology. Earth is unique among the rocky planets in the Solar System because it is the only planet with oceans of liquid water on its surface.

Water also plays an important role in the world economy. Approximately 70% of the freshwater used by humans goes to agriculture. Fishing is a major source of food for many parts of the world. Much of the long-distance trade of commodities is transported by boats through various bodies of water. Large quantities of water, ice, and steam are used for cooling and heating, in industry and homes. Water is an excellent solvent for a wide variety of substances, both mineral and organic; as such, it is widely used in industrial processes, and in cooking and washing

In reverence to practically the most important resource to human existence, World Water Week in Stockholm originally began as the Stockholm Water Symposium in 1991 and has been convened annually ever since. A different theme is selected each year, ultimately geared at tackling the world’s greatest challenges, such as the climate crisis, poverty, and the loss of biodiversity.
