DECLINING GROUNDWATER LEVELS
Groundwater is the largest reservoir of freshwater.
People depend on it for agriculture and their daily lives. Groundwater depletion has become a serious issue for many years, as it is used up faster than it can be recharged by precipitation.
The rate of depletion has more than doubled since 1960.

FRESH WATER OR HOW TO FEED 10 BILLION PEOPLE BY 2050 IN A WARMING WORLD?
The global shortage of the fresh water in the nearby future is eminent and and has become already a social and humanist disaster.
FRESH WATER STRICTLY LIMITED
Abundant water exists on our planet, 97.5 % is salt water in the oceans. Freshwater just 2.5 %!
DETERIORATING WATER QUALITY
The quality of surface water will deteriorate, leading to increased excessive plant and algal growth, loss of bio-
