# Stockholm Water Prize

Presented annually since 1991, the Stockholm Water Prize is an award that recognizes outstanding achievements in water related activities. Over the past three decades, Stockholm Water Prize Laureates have come from across the world and represented a wide range of professions, disciplines and activities in the field of water.
Any activity or actor which contributes broadly to the conservation and protection of the world's water resources, and to improved water conditions which contribute to the health and welfare of the planet's inhabitants and our ecosystems, is eligible to be nominated for the Stockholm Water Prize.
The Stockholm Water Prize Laureate is announced each 22 March at the UN World Day for Water and honoured each August during the World Water Week in Stockholm at a Royal Prize Ceremony and Banquet in the Stockholm City Hall. At the ceremony, the Laureate receives the prize from H.M. King Carl XVI Gustaf of Sweden, who is the patron of the Stockholm Water Prize.
The prize, created and financed by the Stockholm Water Foundation and administered by the Stockholm International Water Institute (SIWI) , includes a US$150,000 award and an Orrefors crystal sculpture.
The Stockholm Junior Water Prize is also administered by SIWI and awarded during the World Water Week in Stockholm each August.

## Past winners and official motivation

2024: Taikan Oki
2023: Andrea Rinaldo, for groundbreaking work with a major impact on several academic fields, including hydrology, hydrogeomorphology and epidemiology. His research is used to protect biodiversity and stem the spread of disease.
2022: Wilfried Brutsaert, for his groundbreaking work to quantify environmental evaporation, helping to make accurate predictions of the impact that climate change has on local rainfall patterns and water sources. Brutsaert is the world’s leading authority on terrestrial evaporation. Such evaporation is a crucial aspect of the water cycle but very difficult to measure or estimate, particularly on a local level.
2021: Sandra Postel
2020: John Cherry, Professor Emeritus from the University of Waterloo in Ontario, Canada. He undertook research on the migration of contaminants in groundwater and he participated in the development of technologies for groundwater monitoring and remediation thus "revolutionizing groundwater research". His research resulted in a "paradigm shift in groundwater pollution control measures", leading to new groundwater remediation guidelines to be adopted in the United States and other countries in the 1990s.
2019: Jackie King, Extraordinary Professor at the Institute for Water Studies, University of the Western Cape, South Africa, won the award for her contributions to global river management. She is internationally recognized for developing approaches to analyze costs and benefits of water resources development, especially emphasizing the need to consider environmental flows, and for her advocacy among transboundary water decision-makers at all government levels.
2018: Bruce Rittmann and Mark van Loosdrecht won the award together for revolutionizing water and wastewater treatment. Their research has demonstrated the possibilities to remove harmful contaminants from water, cut wastewater treatment costs, reduce energy consumption, and even recover chemicals and nutrients for recycling. Mark van Loosdrecht is Professor in Environmental Biotechnology at Delft University of Technology, The Netherlands. Bruce Rittmann is Professor of Environmental Engineering and Director of the Biodesign Swette Center for Environmental Biotechnology at the Biodesign Institute, Arizona State University, USA.
2017: Stephen McCaffrey, "trailblazer in international water law" won the award "for his unparalleled contribution to the evolution and progressive realization of international water law". He is a distinguished Professor of Law at the University of the Pacific, McGeorge School of Law, in Sacramento, California, USA.
2016: Joan Rose, Professor at Michigan State University, USA, for “The nexus of water-related microbiology, water quality and public health is rife with uncertainty – in both theory and practice. The world is blessed with few individuals who can tackle the increasing and changing challenges to clean water and health, starting from state-of-the-art science through dedicated and original research, then moving to professional dissemination, effective lobbying of the legislative arena, influencing practitioners, and raising the general awareness. Joan Rose is the leading example of this extremely rare blend of talents.”
2015: Rajendra Singh, water conservationist and director of Tarun Bharat Sangh (TBS), India, for “today’s water problems cannot be solved by science or technology alone. They are instead human problems of governance, policy, leadership, and social resilience. Rajendra Singh’s life work has been in building social capacity to solve local water problems through participatory action, empowerment of women, linking indigenous know-how with modern scientific and technical approaches and upending traditional patterns of development, resource use, and social norms.”
2014: John Briscoe, Founder and Director of University-Wide Harvard Water Quality Initiative, and for 20 years with the World Bank, for "unparalleled contributions to global and local management of wa ter - contributions covering vast thematic, geographic, and institutional environments-that have improved the lives and livelihoods of millions of people worldwide.”
For his "unparalleled contributions to global and local management of water - contributions covering vast thematic, geographic, and institutional environments-that have improved the lives and livelihoods of millions of people worldwide.”
2013: Peter Morgan, Director of Aquamor, a not-for-profit in Zimbabwe for "his work to protect the health and lives of millions of people through improved sanitation and water technologies. Over the past four decades, Dr. Morgan has invented and advanced low-cost practical solutions to provide access to safe sanitation and clean water that are being used by millions of people worldwide".
2012: International Water Management Institute, Sri Lanka “The International Water Management Institute is the foremost organisation in agricultural water management. Their work has led to new policies and investments in agriculture that have not only enabled more productive use of water, but have enhanced food security, economic development and environmental health around the world.”
2011: Stephen R. Carpenter, United States "Professor Carpenter has shown outstanding leadership in setting the ecological research agenda, integrating it into a socio-ecological context, and in providing guidance for the management of aquatic resources".
2010: Rita R. Colwell, United States "Dr Rita Colwell’s numerous contributions towards solving the world’s water and water-related public health problems, particularly her work to prevent the spread of cholera, is of utmost global importance. Through her research on its physiology, ecology, and metabolism, Dr Colwell advanced the fields of mathematics, genetics and remote sensing technology and not only as they relate to these bacteria but to the prevention other diseases in many developing countries."
2009: Bindeshwar Pathak, founder of Sulabh International
For his wide-ranging work in the sanitation field to improve public health, advance social progress, and improve human rights in India and other countries.
