It is essential to understand that water is one of the most critical parts of the economy of every country, similarly to other energy resources. Of course, everything depends on water quality and availability, but it is something that depends on the local community.
Apart from that, since global trade is a new thing, water is also considered as a collective and comprehensive resource. According to the U.N., water usage is growing twice the rate of population growth, which creates severe issues when it comes to this particular resource.
They have stated that unless they reverse this trend, the water stress will have by 2025, and two-thirds of the population will have these issues.
That is the main reason why experts are finding ways to improve sustainability and the ability to share the water because it is one of the most significant challenges of the 21st century that we are currently facing.
When it comes to the economy, water is both subtle and complicated force that can affect it. It features a single constraint that will help you expand the city, and according to corporate executives and bankers, it is one of the main parts of the economic growth of some nation.
So we decided to help you get an answer to the question: What is a national water footprint?
Have in mind that water footprint depends on the number of local resources that one nation uses to produce both services and goods for one country.
Therefore, it includes footprint required for industry, agriculture as well as domestic water use so that they can determine the assimilation capacity as well as the total volume of water used within the country.
You will also be able to use this particular idea to measure every administrative unit such as river basin, province, a city as well as the entire world.
Have in mind that in perspective of consumption, the national water footprint depends on all services and goods consumed by people that are living in a specific country.
At the same time, it can be used inside and outside of it, depending on whether people are importing or producing it. Apart from that, you will be able to determine and measure water consumption based on administrative units similarly as with production footprint.
Both consumption and production water footprints will tell you a story about the overall use of water as well as how much people are dependent on external water resources, which could be great for governing the resources and creating economic development, international trade relations, and food security.
For instance, the water footprint used for production purposes will measure the amount of pressure that industries are putting on local water resources with an idea to create a unique basis on whether there are ways for sustainability.
Have in mind that the water footprint of consumption will reflect the standard of lifestyle choices and living in the nation.
Therefore, you will have to understand the calculation on consumption within the border, because that is a first step that will help you assess the external water dependence, and find ways to improve the food security as well as agriculture.
Remember that countries that have limited water resources such as the Middle East, Mexico, and North Africa must import goods so that they can meet the needs of the population. This is also the fact for countries that feature limited land areas such as Singapore and Japan.
For instance, Europe is rich in water resources since it has land areas, which means that almost 40% of water footprint goes outside the country through trading for countries with limited amounts of water.
At the same time, the differences tend to vary from nation to nation when it comes to consumption.
In the USA, for instance, the average water footprint is enough to fill an Olympic swimming pool per person, which means 7,800 liters of water per person approximately daily.
On the other hand, in China, the footprint is 1071 cubic meters or 3000 liters per person. Differences between the external and internal footprint of consumption are significant as well.
For instance, in Netherland, 95% of water footprint is all across the globe through imported goods, while Paraguay and India feature 3% of external water consumption.
Everything depends on numerous factors and circumstances so that you can determine the water footprint of products that you have consumed.
Some low agricultural yields require large water footprints per harvested crops, which is why developing countries have large water footprint as well as consumption.
Have in mind that nations from all across the globe are facing challenges when it comes to water consumption and drought. The question is, what countries should do to reduce this particular problem.
The best way to reduce water footprint is to create a long-term strategy such as agricultural shift that will require less water for the crops, especially in areas that have limited amounts such as Australia.
For instance, in there, the majority of water is used for food sources, and farmers around the world are using flood irrigations and wastewater to reduce the intake of fresh water.
Therefore, the dip method is something that should affect the overall consumption because it may save 50% of the water that you can use based on flood irrigation. Apart from that, the yields will be much higher when you initiate a drip irrigation system developed in Israel.
We live in a world in which technology is all around us, and it can play a role in helping countries reduce the water footprint. For instance, in Los Angeles, desalination is a solution that was implemented by some countries such as South Africa, and the idea is to recycle wastewater and reduce the footprint in the long run.
They have to create sewage pipes that are directly going into treatment facilities, where high-tech equipment will purify water, clean it, and digest organic materials inside.
The water will have to undergo various levels of cleansing, and finally, you can get it back and use it for irrigation purposes, and showers. This is also a great thing if you have plenty of rivers with freshwater that you wish to preserve since you will be able to reduce pollution levels.
