Sources of nitrogen in rivers worldwide

We analyse sources of nitrogen (N) in rivers worldwide in a spatially explicit way. For this, we link three global models.

Today, many rivers are polluted. Over half of global N in rivers is from anthropogenic sources with large spatial variabilities. In the future, rivers may be more polluted. We explore linkages between sustainable development goals (SDGs) and pollution sources. Reductions in river pollution (SDG6, 14) call for sustainable human activities (SDG2, 11) under global change (SDG8, 13).
