Three Types of Water Footprints (Blue-Green-Gray)

We can all agree that everything we do, consume, purchase, use, sell, and eat requires water so that you can do it. Therefore, the water footprint is a measurement and analysis of the amount of water required to produce a single product or goods and services that we use daily.

You can measure it as a single process such as growing potatoes, for products such as a leather jacket or pair of jeans, or for the fuel that you place inside the car.

On the other hand, large companies are using significant amounts of water for creating some product, which also affects the overall amount of water required for things that surround us.

Therefore, water footprint is the critical measurement that will provide you an exact idea on how much water one country has been consumed as well as the global amount of consumption that will help us reduce the footprint so that we can avoid scarcity that will happen in the future.

In here, we will present your comprehensive understanding as well as types of water footprint that you should remember before you start saving.

What Is Water Footprint?

The water footprint is a measurement of humanity's requirements of freshwater when it comes to creating products and services that we use daily. At the same time, it allows us to get the answer to numerous questions for governments, companies, as well as individuals such as:

  • What is the water dependence of your organization and supply chain?
  • How well are regulations protecting freshwater resources that surround us?
  • How secure are energy and food supplies based on the amount of freshwater used for them?
  • What should you do to reduce water footprint so that you can help both the environment and the people around you?

Everything depends on the question you wish to ask, but have in mind that water footprint is measured in cubic meters per ton of production, per unit of currency, per hectare of cropland and by using, other functional groups based on specific industry and requirement.

Therefore, the water footprint will help you get a thorough understanding of what purposes we use limited freshwater resources and how to stop the general pollution that happens all around us.

By determining this particular impact, you will be able to learn how to reduce the water intake and use an action that will help you mitigate the consequences.

Have in mind that we can differentiate three main components of water footprint: green, grey, and blue. These components together will provide you a thorough picture of what is happening with water as well as the percentage of consumption with the volume of freshwater.

Differences Between Direct and Indirect Water Usage

Have in mind that water footprints tend to provide you both indirect and direct possibility for its usage especially when it comes to products, processes as well as sectors that require water consumption and pollution throughout the lifecycle of some product or service.

At the same time, you will be able to use a water footprint to measure the amount of water that you require for producing specific services and goods.

Therefore, direct water footprint is water used by individuals, while indirect ones are the number of water footprints used by products and goods that you consume.

Three Types of Water Footprints

Green Water Footprint

Have in mind that green water footprint includes consumption of water from precipitation that you store in the root zone of the soil, and the percentage of the amount, which is transpired, evaporated and incorporated by plants. It is essential for agricultural, forestry, and horticultural products, which is why we call it green water footprint.

Blue Water Footprint

On the other hand, blue water footprint includes water that you use from the surface or groundwater resource, and you incorporate it into a product taken from its body and returned to another in a different period. In reality, it includes irrigated agriculture, domestic water use, and industrial water use that may affect the general consumption daily.

Green Water Footprint

Finally, the amount of freshwater that we require to meet specific quality standards and to assimilate pollutants is known as grey water footprint. In reality, it represents the footprint which you should discharge due to pollution and that it goes from freshwater resource to a pipe directly or indirectly through impervious surfaces, leaching from the soil or other diffuse sources that may lead to different perspectives.

The Relation Between Water Use and Consumption

The main goal of water footprint is in the aspects and impacts that humankind is making when it comes to freshwater systems. It can be ultimately linked to human consumption and cause issues such as water pollution so that you can address and understand the supply chains and production.

Have in mind that water consumption, as well as shortages, are closely connected with the global economy that surrounds us. Numerous countries have found ways to externalize their water footprints, especially when it comes to importing water-intensive goods.

This will place the pressure on water resources in the exporting regions, where wise water conservation and governance are lacking. Therefore, not only governments but consumers are also playing a role in global water footprint and management of water resources.

How to Reduce Individual Water Footprint?

Reduce Energy Expenses By Using Alternative Sources

Have in mind that the electricity required for daily enjoyment is one of the biggest water consumers in the USA. Therefore, when you light a 100-watt light bulb for ten hours and achieve one kilowatt-hour of electricity, that will require between twenty and sixty gallons of water by nuclear or coal power plant to produce it. Have in mind that the largest consumers of electricity in the home include water heaters, refrigerators, home heating systems, and air conditioning units. Therefore, you should go for wind and solar energy so that you can reduce electricity expenses, which will ultimately reduce your water footprint.

Water Footprint Of Foods

By learning how beverages and foods that we consume take water throughout its lifecycle, you can create understanding and eat only things that are not affecting the environment. For instance, a pound of beef requires 1900 gallons of water powerpoint, while pasta features 220 gallons per pound. Walnuts and almonds are water-intensive foods and need between 1200 and 2100 gallons of water per pound. Therefore, you should learn what food feature most massive water footprint so that you can avoid them altogether.
