This comment prompts scholars to include eutrophication more often to water quality assessments as it is globally one of the major water-related environmental problems but remains underrepresented in contemporary assessments, water policies and international targets such as the United Nations Sustainable Development Goals (SDGs). What we scholars can do is to mainstream eutrophication in our global water assessments, and that way ram it to a higher position in political agendas. The recent advances in global nutrient models and datasets, as well as Earth observation approaches, allow novel horizons in this regard. Now is the time to scrutinize these novel opportunities. Our take to this quest here is to develop a model protocol that produces gridded eutrophication maps from total nitrogen and total phosphorus data. We also developed analogous methods for biochemical oxygen demand and total dissolved solids.
