Global Approaches to Address the Nitrogen Issue: Expected Effects on Groundwater Nitrate Pollution

Nitrogen (N) provides great benefits as a fertilizer for food production and material industrial production. However, its use simultaneously induces N pollution, which threatens the health of human beings ecosystems due to low efficiency in anthroposphere. This is issue—a tradeoff between large threats. It our responsibility have future generations inherit sustainable by resolving issue. Groundwater nitrate pollution form that should be addressed prevent harm animal through drinking water aquatic excess eutrophication. Links groundwater cycling issue are reviewed provide information international domestic actors address issue, indicate research needed comprehensively Concretely, global local links with processes overviewed. The status summarized comprehensive framework grasp entire introduced, i.e., driver–pressure–state–impact–response (DPSIR) framework. Programs projects tackling Japan around world summarized. Research required on contributes discussed, expectations indicated.
