In 2050, more people will be at high risk of water pollution due to increasing Biochemical Oxygen Demand (BOD), Nitrogen (N) and Phosphorous (P). By 2050, a drier climate change scenario coupled with medium levels of income and population growth projects that 1 in 3 people will be at high risk of nitrogen pollution (2.6 billion people or an increase of 172%); 1 in 3 people will be high risk of phosphorous pollution (2.9 billion people or an increase of 129%).

Future projections of river nutrient export to the global coastal ocean show persisting distortion in nitrogen and phosphorus. This distortion, along with the projected increase in global water use by 20 to 50 percent above current levels by 2050, could exacerbate water quality issues. The projections for nitrogen and phosphorus levels in water bodies from 2020 to 2050 indicate a significant increase in pollution levels. This underscores the urgent need for sustainable water management and efforts to reduce nutrient pollution.
