 Water footprint as a tool for selection of alternatives (Comments on “Food Recommendations for Reducing Water Footprint”)

Please find some of my observations.

            The title is descriptive, and it draws attention to the subject on which the authors have focused.

            The abstract is a concise summary of research conducted. The opinion presents the views of researchers on the strengths of the water footprint, from point of view blue, green, and gray. The authors extend these recommendations to the food industry. Do not add any citations in the abstract. It is recommended to change that phrase.

            The structure of the paper was organized in several sections. Introduction provide background information with a brief summary of existing literature. The main body of the article it refers to the significance of the individual components, by color, of the water footprint in terms of the sustainability of food production and their evaluation criteria. The topic is relevant and interesting. The water footprint associated with food production varies depending on factors that vary widely. How do the authors see that studies can be relevant in such different conditions - geographical area, season, gastronomic culture, authenticity of recipes, etc which can be difficult to interpret?

In the conclusions section, the authors summarize the arguments presented, but the support of these statements should be better proven.

In addition, summarize the applications and implications of your opinions, why would it be so important in the food industry.
