Each year since 1997, upwards of 10,000 high school students from over 30 countries compete to win the Stockholm Junior Water Prize, one of the world’s most prestigious youth science awards.

The competition is open to students between 15 and 20 years of age who have conducted water-related projects of proven environmental, scientific, social or technological significance. Initial competitions are held at local, regional, state and national levels in each country. The national winners are then invited to World Water Week in Stockholm for the final competition and for the International Award, which is presented by H.R.H. Crown Princess Victoria of Sweden.

This year, for the first time, the national winners presented their research and innovations on the iPoster platform. You can view them here.
