The sustainability of the water resource should be a transversal axis in environmental, agricultural, energy, industrial / commercial, foreign affairs and international cooperation policies. International cooperation and aid should focus on those parts of the world where there are areas of water scarcity and increased pollution.


It all starts because the human body is made up of 65 to 70% water. The availability of fresh water in the world is 1% of the total water and of that 1% it is necessary to make drinkable, distribute and treat the amount that humans need to consume to live without getting sick. To this we add that in 2010 we approached 6,866 million passengers mounted on Earth, and that in 1949 there were 5 thousand large hydraulic dams on the planet, which at the end of the 20th century reached 45 thousand with their consequent displacements. of human groups, almost always indigenous, coupled with the destruction of ecosystems in a clear competition between obtaining energy and the availability of the resource downstream.

The water footprint is a concept that arises worldwide with the intention of counting the volume of fresh water necessary to produce the goods and services that a person consumes in a period of one year and inspired by the concepts of ecological footprint and carbon footprint. This simple concept, but of great depth, has served and serves as a massive teaching tool, easy to see and understand for all, when it comes to water, the most essential of the planet's resources, and when it comes to water. responsibility that we all have before its use, being that this is a common good, irreplaceable for any form of life that exists and that is increasingly scarce in certain parts of the world.

Arjen Hoekstra, creator of the concept (2002), establishes that the water footprint refers to the volumes of water consumption and the pollution behind the water consumption of each one of us, and later extends the concept to a country scale. He implemented the interdisciplinary field of the water footprint and the virtual analysis of water exchange, an area of ​​research that addresses the relationship between water management, consumption and trade / industry. It talks about the water footprint of national consumption and refers to the total water consumption that is used to produce goods and services consumed by the inhabitants of a nation, and because not all the goods and services consumed in a nation are produced in itself, the water footprint of national consumption separates it into two parts, use of national water sources and use of transboundary water sources.

Nowadays, in the countries of the world, there is a tendency to think of national plans that consider options for reducing the demand for water in addition to the traditional options for water supply, but few countries tend to incorporate the variable sustainability of the consumption of the resource and much less they incorporate the variable water footprint -water consumption and pollution behind consumption- when, for example, products with high water requirements are imported. What we could bet heavily on loaches is that when products with a high water footprint are exported, one does not tend to think that, deep down, the exporting country is paying for the scarcity of water resources within its borders and favoring savings of the resource in the country you are importing.


The sustainability of the water resource should be a transversal axis in environmental, agricultural, energy, industrial / commercial, foreign affairs and international cooperation policies. International cooperation and aid should focus on those parts of the world where there are areas of water scarcity and increased pollution.

The truth is that the water footprint of countries tends to vary according to their consumption patterns, their climatic conditions and the water use practices of the place where consumer goods are produced, but it is also true that to the extent that that we use accessible water in each country sustainably, polluting less, and do the same with less water, to that extent we will be managing water as "the" strategic resource and considering it as the most essential of the planet's resources.

Why think of an indicator or tool that is easily understood by citizens equivalent to the water footprint?

The growing scarcity of water resources in the world is known to all, either due to the contamination of bodies of water, the lack of treatment of sewage, the increasing deforestation of forested areas or river basins, or simply the lack of the application of public policies directed to the integral management of the resource. It is also known by all the increasingly growing limitation of having a continuous supply of water throughout the year, worse still, the inaccessibility of water in areas of the world where availability is increasingly precarious, the population goes increasing and increasing the danger of extinction of various species due to contamination of bodies of water. Well, tools such as the water footprint inform and in turn create a direct link between the existing problem and how and with how much each of us, as an individual or as a country, can contribute to not aggravating or mitigating the problem from our showers, from our tables, from our consumption habits, from our communities, from our international treaty signatures or from the goods and services markets in which we participate.

What we can do

As educated and responsible consumers of the water resource we can apply many behaviors that directly reduce the water footprint, and they range from installing water-saving wells, or simply introducing a plastic bottle filled with water in the well's tank; installing water-saving shower systems, even closing the shower tap while we lather; install atomizer systems that inject air into the water from the sink taps or simply turn off the tap while we brush our teeth; Do not use the well as a garbage can, spread and teach these practices to others, and above all do not pour polluting liquids such as medicines, oils or paints through sinks or sewers.

In figures

Let's review how much water it consumes, what is the water smell of various cases:

Refine 1 barrel of crude oil - 7,000 liters of water required

Manufacture a one-ton car - 400,000 liters of water are required between the production of the materials that compose it and its construction.

Make a sheet of paper - 10 liters of water are required for 80grs / m2 type paper

Grow one kg of potatoes - 900 liters of water are required

Grow one kg of rice - 3,400 liters of water are required

Produce one kg of red meat - 15,500 liters of water are required

Produce one kg of chicken meat - 3,900 liters of water are required

We will always have, as educated and responsible consumers, the freedom to choose, buy and consume the product that we consider with the most transparent production, respectful of the environment and with the lowest water footprint, beyond covering a need. As educated citizens we will have the clarity and freedom to choose the representatives who offer us laws, policies and programs that consider the sustainable use of the water resource as a transversal axis or demand that it be incorporated into the options presented.

Few lines will always be written about water, the most essential of the planet's resources and the majority component of the human being.
