The murky future of global water quality: New global study projects rapid deterioration in water quality
While California’s four-year drought is forcing the most severe mandatory water restrictions in the state’s history, another water crisis is brewing that will affect far more people and a much greater territory – the planet at large.
According to a global study by the International Food Policy Research Institute and Veolia, the world is on a path toward rapidly deteriorating water quality in many countries. The first-of-its-kind study indicates that up to 1 in 3 people will be exposed to a high risk of water pollution in 2050 from increased amounts of nitrogen and phosphorous. Up to 1 in 5 people will be exposed to a high risk of water pollution reflected by increased levels of biochemical oxygen demand (BOD).
Even using the most optimistic socio-economic models, water quality is projected to rapidly deteriorate over the next several decades which, in turn, will increase risks to human health, economic development and thousands of aquatic ecosystems in developed and developing economies alike.
ORBIS is powered by ESPAS, the European Strategy and Policy Analysis System, a unique inter-institutional project aimed at strengthening the EU's efforts in the crucial area of forward planning. ESPAS brings together the European Commission, the European Parliament, the Secretariat General of the Council of the European Union and the European External Action Service to strengthen the Union's collective administrative capacity to identify and analyse the key trends and challenges, and the resulting policy choices, which are likely to confront Europe and the wider world in the decades ahead.
