The Global Freshwater Crisis
The vata planet Saturn in Virgo has precipitated a Water Crisis. Let us see what are the solutions. ( Yesterday Mumbai reported a severe water crisis, like Hyderabad. More bad news are coming in ).
Water is only a finite resource, even though it is universally assumed that global supply is infinite. Only 2.5 % of the global supply is freshwater. The rest is seawater, inacessible in ground water, ice caps and soi. This supply is limited.
Rainfall is the only renewable source of freshwater and per year the global supply is just 50,000 cubic km. Per year global population is increasing by 85 million. Hence the availability of freshwater per head is fast decreasing. The whole planet is overpopulated, with more than 6.5 billion people.
That limited source of freshwater is polluted, diverted and depleted by foolish humans. ( " Lord, what fools these mortals be", said Shakespeare ). More than one billon people lack access to safe, drinking water. UN says 31 countries face water stress and scarcity. The water stress countries are UAE, Kuwait, Saudi Arabia, India, Israel, Mexico etc.
By 2025, when the earth will be populated by an additional 2.5 billion people, 70% will be living in conditions of serious water shortage and 30% will be living in conditions of acute water scarcity.
To conserve Groundwater, Gabion structures can be used. More info about conserving Water can be had at the Central Groundwater Authority site.
A great warning has been given by World Resources " The world's
thirst for water is likely to become one of the most pressing resource
issues of the 21st century. In some cases, water withdrawals are so high, relative
to supply, that surface water supplies are literally shrinking and
groundwater levels are being depleted faster than they can be replenished by
precipitation".
In the Arab world, use of groundwater is three times than groundwater recharge.
Saudi is running towards depletion in the next 50 years. Africa's aquifers
are non-recharging and the current depletion is estimated at 10 million cubic
meters. Water tables are falling everywhere in India. Mexico is water scarce. In
Bangkok overpumping has taken its toll. Northern China has eight regions of water
scarcity. Beijing suffers from a massive water crisis.
