    Will lack of water lead to a new global crisis?

    Did you know that the world’s reserves of food supplies are lowest for the past 50 years and represent only 14% of annual demand, despite the fact that food prices are on the decline?

    Serious global crisis threatens to world, whose effects are cross-border conflicts, mass migrations from the affected areas, and finally a new world war.

    It is assumed that by 2030.g. will come to 50% greater demand for food and 30% for water, and the main reasons for this are:

    • rapid population growth, which will by 2030.g. exceed 8 billion
    • climate change, caused by the increasing release of CO2 into the atmosphere
    • lack of water, which causes
    • lack of food
    Global warming of planet leads to increasingly smaller amount of precipitation as well as to the melting of icebergs and glaciers, as the largest reservoir of fresh water – which leads to an additional reduction in the capacity of river flows.

    Due to the growing demand for food, there is excessive use of groundwater for irrigation purposes. As the groundwater is very slowly restored, there was a decline in the level on all continents, as in the plains of northern China, which produces about 40% of the grains in the country, groundwater level drops to 1.5 meters per year.

    Disturbing facts:

    • annual groundwater consumption is 160 billion tons more than rebuilt amount
    • producing  one ton of grain requires cca. one thousand tons of water, which means that 160 million tons of grain in the world is produced in excessive and unsustainable pumping of groundwater
    • to feed one person a year one third tons of grain is needed (bread and pasta, meat production), which means that 500 million people in the world feed by taking the reserves of water for future generations
    • 40% of the world’s food comes from irrigated land
    • of all the total water consumed in the world, about 70% of water from rivers or underground sources goes for agriculture, 20% for industry and 10% for other purposes
    The solution for this global crisis is looming in the better use of technology in agriculture and farming. In agricultural production those measures would include the use of more efficient irrigation systems (sprinklers and drippers with lower pressure), the introduction of new technologies of soil tillage by which are kept atmospheric water, and greater use of manure.
