Effective denitrification scales predictably with water residence time across diverse systems
Nitrogen provides a fundamental building block for life. However, some nitrogen species (e.g., NO3) cause water quality degradation and contribute to climatic warming as a greenhouse gas (e.g., N…

Use of inadequate data and methodological errors lead to a dramatic overestimation of the water footprint of Jatropha curcas
In their recent article, Gerbens-Leenes et al. (1) calculated the water footprint (WF, the amount of water required to produce 1 GJ of energy) of several bioenergy crops. One of the most remarkable…
