“…The Water-Energy-Food nexus (WEF) model explored the relationship between water demand, energy requirements and food supplies (Entrena et al, 2023). For statistical analysis, the IBM SPSS Statistics Data Editor 25 allowed linear regressions to be performed to determine the Total Water Footprint (Okutan & Akkoyunlu, 2021). The WEF method also facilitated comparisons between blue and green water footprints (Su, Zheng & Llao, 2022).…”

Objective: The main objective of the article was to investigate the use of the water footprint as a sustainability indicator through a systematic review of the literature. Method: The PRISMA method was applied. Additionally, the methodology entailed a thorough search in key databases such as Scopus, Springer, and others, utilizing specific criteria to filter and select pertinent studies. From approximately 17,000 studies initially identified, around 2,000 were filtered and 20 were selected based on criteria like relevance, availability, and the match of publication dates and language, among others. This meticulous approach aimed to ensure the quality and transparency in evaluating how human activities affect water availability and quality. Results and Discussion: Bibliometric results enabled the description of the selected studies, while content analysis facilitated the identification of tools and strategies related to the water footprint applied across various economic sectors. It was concluded that there are several effective tools for measuring, assessing, and managing the water footprint, with their application standing out in a variety of productive sectors and social strata. However, despite technological and methodological advancements, there is still a notable lack of research demonstrating a significant global reduction in the water footprint, highlighting the need for more effective strategies for sustainable water resource management. Research Implications: The study’s implications underscore the significance of water footprint measurement, assessment, and management tools, which are applicable across a variety of economic sectors and social strata. The scarcity of research demonstrating a significant reduction in the water footprint implies an urgent need to promote applied research for water footprint reduction, rather than merely limiting to its measurement. Originality/Value: The originality and value of the study lie in its systematic and comprehensive approach to using the water footprint as an indicator of sustainability.

“…It is seen that students have higher CFP and WFP values compared to the national diet before education. A study evaluating the diet-related WFP of university students in Turkey found it to be 3901 L/day [ 65 ]. It is seen that university students have more negative effects on the environment than the general population.…”

There are studies on the effect of general nutrition education on diet quality and anthropometric measurements, while studies showing the effectiveness of sustainable nutrition education, which also addresses the effect of food on the environment, are quite limited. This study aimed to investigate the effects of sustainable nutrition education on diet quality, anthropometric measurements, and the carbon footprint (CFP) and water footprint (WFP) of diet. A total of 160 university students received 1 h of sustainable nutrition education for 6 weeks. Before, at the end of, and 2 months after the courses, 24 h food consumption records were taken to assess diet quality and CFP and WFP values of diet, and Mediterranean diet (MedDiet) and Healthy Eating Index (HEI)-2020 scores were evaluated. The results of the study showed that sustainable nutrition education increased MedDiet score by 1.86 points and HEI-2020 score by 7.38 points. This education program also decreased body weight, body mass index (BMI), fat mass, and neck circumference. Sustainability education has a positive impact on calcium, potassium, and magnesium intakes, a negative impact on vitamin B12 and zinc intakes, and no effect on total protein intake. Education resulted in a 22% reduction in CFP and a 10% reduction in WFP.

“…and building types. The figures should also vary across regions/provinces; however, the water demand for toilet flushing in urban can be assumed as 18-24 lpcd, considering the average needs of flushing reservoir volumes (DIN 1989;Belmeziti et al 2013;Okutan & Akkoyunlu 2021).…”

“…This study assumes that the water demand for toilet flushing is the same for all urban areas in all provinces in Türkiye. Thus, the water demand for toilet flushing is 24 lpcd in residential buildings (DIN 1989;Okutan & Akkoyunlu 2021). That sums to a daily water demand of 144 L for a family of six members, monthly water demand of 4.32 m 3 , and annual water demand of 53 m 3 in the residential buildings.…”

In this study, the economic feasibility of rooftop rainwater harvesting of residential and public/commercial buildings for all 81 provinces of Türkiye is assessed. The Rippl method (RM) is used for optimal storage tank estimation. The net present value (NPV) and the discounted payback period (DPP) are used for economic analysis. Two scenarios were assessed using RM for (I) residential buildings and (II) public buildings. Optimal storage tanks for scenarios I and II were estimated by the selection of minimum roof areas to supply the demand for toilet flushing water for above 95% volumetric reliability. ArcGIS 10.2 was used to illustrate nationwide results of (1) roof areas and storage tank volumes, and (2) the economic analysis. The average DPP of rainwater harvesting system is 36 years for residential buildings and 23 years for public buildings. Based on NPV analysis, 17 out of 81 provinces are economically feasible for residential buildings. The feasibility status in public buildings is 43 economically feasible and 38 infeasible. More savings in public buildings can be obtained in a relatively shorter DPP. Furthermore, regularization is more effective in public buildings than residential buildings.
