Researchers come for the first time with a well-substantiated and fairly precise calculation of the amount of groundwater on earth. Based on multiple datasets and more than 40,000 groundwater models, they establish that 23 million (km³) of groundwater can be found on earth. Of this, 0.35 million (km³) are younger than fifty years.
Solution to the Decline in Freshwater Supply
The research also shows that below six percent of the ‘modern’ groundwater within the top two kilometers on earth can be renewed within the period of a lifetime. Secondary cities or small towns are generally not served by national public water companies. Although municipalities have the power to operate the water service on a decentralized basis, they often lack the capital and technical expertise to do so.
Municipalities often prefer to improve the operational performance of existing regional or local public water companies or to strengthen community management. In other cases, they choose to use the technical expertise of the private sector to provide more efficient, affordable and sustainable water and sanitation services. There is no ready-made solution to the many challenges of improving water and sanitation services.
NASA data shows the world is running out of water
Experts from the space agency NASA analyzed the received images from satellites and came to the conclusion that in the next hundred years many countries will remain without water. Scientists have drawn attention to the fact that the supply of fresh water is very quickly reduced. The main reason for this is global warming and a high concentration of carbon dioxide.
On the Earth drinking water ends
According to scientific experts, first of all, such countries as Nepal, the Caucasus and the north of India will suffer from the drought. Also, states that are in the south of the United States of America, Belgium, the Netherlands can suffer.
As for the countries of Europe, in the nearest hundred years the drought will not threaten them. In Russia, one should not be afraid of the disappearance of water to the inhabitants of Eastern Siberia and the Far East.
According to scientists, so far nothing can be done to increase the amount of fresh water on Earth. However, in the near future there is a chance to change something, since NASA representatives have some ideas that will help to solve this problem.
Developing action plans for local financial institutions to help them better understand the water sector and provide appropriate financial products. In Benin, local commercial banks are committed to supporting the water sector by providing various financing instruments to enable private operators in small towns to expand service and make new water connections. In the Philippines, the most common type of PPP for EAF in small towns is the Joint Venture which allows the private sector to provide equity or loans.
Our Shrinking Fresh Water Supply
Let’s not forget: the water we pollute is the same one we drink. So, to keep fresh water clean and clean, it is better to take care of it; it begins with the supply.
Freshwater is very unevenly distributed on the surface of the planet.
Just look at a world map. However, it should be kept in mind that a country or region may be relatively rich in fresh water and poor in drinking water (even with rather wide drinking criteria). For example, Bangladesh is a country where one of the great rivers of the planet runs but which is sorely lacking in drinking water. The same goes along the Niger and this may be due to sediments carried by the river or potential infections it contains, or both.
That said, in Europe we have a lot of fresh water, but it is less and less drinkable by the fault of the Man who always considered this water as a public good, free and usable to the envy, we do not We will soon realize how much it represents (this is already the case in Brittany, for example), which will be paid for by the community as a whole and not only by the polluters.
Simply because things are difficult to quantify and that justice has a logic, my faith, very different from the ecology, in this area in any case, if only because it works a posteriori, so that the water is already polluted when she can intervene.
