  • Winner: International Commission for the Protection of the Rhine | River Rhine, Transnational (Europe)

    The International Commission for the Protection of the Rhine (ICPR) received the award for bringing Europe’s River Rhine back to life following a devastating chemical accident in 1986, which wiped out nearly all biological life. Prior to the accident, industrialisation and burgeoning populations had already caused major degradation to the river and as early as the 1960s, the Rhine, which flows through six countries, was notoriously known as the ‘sewer of Europe’. The restoration of the Rhine has taken the best part of a century, and involved extensive transboundary river management and cooperation. Now, almost all of the 58 million inhabitants of the Rhine catchment are connected to urban wastewater treatment plants, water quality has improved considerably and inventories show that fish species composition in the Rhine is almost back to what is was before the chemical spill.

  • Winner: Mara River Water Users Association | Mara River, Kenya

    With a clear vision and in anticipation of potential conflict arising over scarce water resources, the community-based Mara River Water Users Association overcame significant challenges and successfully collaborated with farmers, community groups, NGOs, consultants and many other stakeholders to implement the Mara River Environmental Management Initiative. Almost 1000 farmers within the basin have been educated and had their farms terraced, a 40km stretch of riverbank has been restored, and 40 springs have also been protected – providing easy access to clean water and reducing water-borne diseases. These on-ground works were targeted through an integrated program of catchment and river management activities. Watch video here

  • Winner: Charles River Watershed Association | Charles River, USA

    In 1965, when the Charles River Watershed Association (CRWA) was founded, the river commonly ran in colors, depending on the paint being manufactured nearby. Sewage overflows were common and outfalls discharged industrial waste.  Rowers who fell into the river routinely received tetanus shots and a course of antibiotics, and as recently as 1996, though the river was no longer a palette of colors, water quality had scarcely improved. The Charles became one of the USA’s cleanest urban rivers following its transformation, the story of a small science and engineering-oriented, grassroots nonprofit watershed association and the concerted efforts of many others.
