| Description: |
Since the development of industrial nitrogen (N)-fixing processes early in the 20th century, anthropogenic N inputs have grown to dominate the global N cycle, and have become the main sources of N in most watersheds affected by humans. Potential implications for increased N load from Net Anthropogenic Nitrogen Inputs (NANI) include increased eutrophication, loss of species diversity and habitat, and growth of hypoxic areas ('dead zones') in coastal waters.
