Did you know that sea urchins can warn of water pollution and that durian rind can purify water? These are just two of the many innovative solutions that have been awarded with the Stockholm Junior Water Prize since the international competition started in 1997.

Every year, tens of thousands of students aged 15 to 20 enroll in the Stockholm Junior Water Prize competition with bold water project proposals of environmental, scientific, social, or technological significance. In each of the 38 participating countries, a national winner (team or individual) is chosen who then gets to represent the country in the international finals, usually held in Stockholm during World Water Week, at end of August.

The international winner takes home a USD 15,000 award and a blue crystal prize sculpture, which is presented by the Prize’s Patron, H.R.H. Crown Princess Victoria of Sweden. In addition to picking a winner of the Prize, the jury can also choose to honour an especially worthy project with a Diploma of Excellence. Starting in 2020, a third prize category is introduced, the People’s Choice Award, which lets the audience vote for their favourite project.

By their own account, most finalists feel like winners due to the many friendships and experiences the competition brings. It also offers opportunities to learn more about science and meet leading water experts. Maybe most rewarding of all – many of the students really develop smart water solutions that make a difference not only to themselves but to their communities.

“For me, participating in Stockholm Junior Water Prize was life changing!” says Kishoth Navaretnarajah who represented Sri Lanka in the 2013 finals. “It got me interested in the environment and water research. I also felt I wanted to do something for my community. We received support to develop the project that took us to Stockholm, a method to optimize soil moisture using solar evaporation, which requires less water and gives higher yields. It is now used in my home community.”

Stockholm Junior Water Prize is organized by the Stockholm International Water Institute (SIWI), and delivered by independent national organizers, with support from SIWI and in accordance with its prize guidelines.
