When asked about the global water crisis most people do not know the full extended how just how bad things really are. Rather than the problem getting better, it is going to be a whole worse in the near future and it will be a crisis that will affect the globe on a massive scale.
By 2025 it is estimated that around 1.8 billion of people will be living in regions that are water scarce. A total of two-thirds of the population around the globe will be in an area of water stress.
Over 780 million people across the world do not have access to safe water to drink. Africa is the worst hit with one-third of the population not having access to clean water. Due to Global Warming by the year 2015 as much as five times the amount of land presently is estimated to be classed as “Extreme Drought”
Worldwide there are over two billion people who have to rely on a well for their supply of water. In China between 25-33% of the population are without the access to clean drinking water.
By the year 2025, there is be an estimated 1 billion more humans on the planet which mean that an extra 1 million m3. per year of water for just the worldwide agriculture. By the year 2035, an extra 15% of water will be required for the increased demand for energy of up to 35%. By the year 2050, the demand for water is expected to grow by 55%.
Agriculture is the biggest usage of water and around 70% of the total worldwide supply of freshwater withdrawals is used in the industry. In the fastest growing economies, this can increase greatly and be up to 90%.
In the U.S the Basin of the Colorado River has lost water of around 65 cu kl between the years of 2004 up to 2013. That is double the total amount of water in Lake Mead. The thermoelectric industry is the larger user of freshwater and it accounts for up to 50% of the total withdrawals.
It is estimated that around 4.5 billion people in the world live within a distance of 50 kilometers of water resources that are dry, polluted or running dry.
The demand for water over the last 40 years has more than quadrupled and the population of the world has doubled. Sub-Saharan Africa is are suffering from the highest amount of countries that are water stressed.
It only takes 12 gallons of water each day for the human body to be sustained and in the U.S the average person consumes around 158 gallons.
By the year 2030, the requirements for global water annually will greatly exceed the total amount of sustainable water available by up to 40%, By the year 2050 one in every five developed countries will have shortages in water supplies.
Fifty percent of the world’s population now live in a country in which the water supply is falling fast. By 2040 a third of the population of the world will be without water. There will also not be enough to be able to supply the demands of the current power and energy industry.
