La huella se define, de manera simplificada, como un indicador de consumo y contaminación de agua dulce. Para ello fueron seleccionados cuatro sectores para evaluar el tipo de huella correspondiente en cada uno: sector doméstico, industrial, agrícola y residuos sólidos. Se siguió la metodología propuesta por Hoekstra et al. La huella hídrica total de los sectores evaluados se estimó en 9 489.58 millones de m 3 , donde el sector de mayor huella fue el agrícola con 4 555.14 millones de m 3 , seguido por los sectores doméstico, de residuos e industrial. Finalmente, es posible concluir la insostenibilidad de la huella hídrica y, por lo tanto, la vulnerabilidad de la ciudad frente a la disponibilidad del recurso. PALABRAS CLAVE:Bogotá; huella hídrica; sostenibilidad; consumo de agua; gestión del agua. ABSTRACTThis article presents the estimate of the Water Footprint of Bogotá city generated in the year 2014. The water footprint is defined, in a simple way, as an indicator of consumption and pollution of freshwater. Four sectors were selected to evaluate the type of corresponding footprint in each: domestic, industrial, agricultural and solid waste. The methodology proposed by Hoekstra et al. was followed. The total water footprint of the evaluated sectors was estimated in 9 489.58 million m 3 , where the sector of higher footprint was the agricultural one, with 4 555.14 million m 3 , followed by the solid waste and industrial sectors. Finally, it can be concluded that the footprint is unsustainable and, therefore, the city is vulnerable considering the availability of the hydric resource.

Water Footprint as A Sustainability Indicator: A Systematic Literature Review

“…On the other hand, the Water Footprint Network (WFN) was used in two (2) studies to 12 estimate the water footprint in the domestic sector, focusing on evaluating both the 'Virtual Water' (VW) and the 'Water Footprint' (WF) and, at the same time, determining the blue water footprint (Zhang et al, 2022;Castilla et al, 2018). WFN provides world-class, fully opensource interactive tools that provide essential data and insights into water use.…”

“…It is therefore suggested that national or regional policies be put in place to incorporate the cost of water into the price of rice products and thereby improve water efficiency. It is estimated that approximately 207.9 m³ of water is consumed for rice, using 90.7 m³ of surface or groundwater (Trujillo et al, 2022;Su, Zheng & Llao, 2022;Gomez et al, 2022;Yu et al, 2022;Wu, Wang & Avishek, 2021;Castilla et al, 2018).…”

Understanding advances and challenges of urban water security and sustainability in China based on water footprint dynamics

“…Compared to the foreign urban WF, in terms of both the WFprod and the WFcons calculated by Cai et al (2019), China's urban per capita WF was obviously lower than that of US cities (Chini et al, 2017) and higher than that of cities in Egypt and Colombia (Wahba et al, 2018;Castilla et al, 2018). The results of Hoekstra and Chapagain (2006) As shown, the urban WF is influenced by a combination of the urban environment, socioeconomic status, governance and technology (Figure 9a).…”

Assessment of the Water Footprint in Low-Income Urban Neighborhoods from Developing Countries: Case Study Fátima (Gamarra, Colombia)

“…Thus, this study can help researchers and decision-makers in similar contexts to carry out WF studies that help identify strategies to reduce pressure on water resources according to socioeconomic conditions. Greater adoption of this methodology in these contexts facilitates understanding the interaction between social relations and economic and natural resources and would improve water management, as in developed countries [72].…”
