    World water emergency: 1,9 billion people at risk of water scarcity. The study in Nature

    Mountains and glaciers all over the world are no longer able to store and store water due to the climatic crisis and this will lead in a few years to a real planetary water emergency with almost two billion people who will literally die of thirst.

    Mountains and glaciers all over the world are no longer able to store and store water due to the climatic crisis and this will lead in a few years to a real planetary water emergency with almost two billion people who will literally die of thirst.



    The alarm was raised by a study published in the journal The Nature according to which a quarter of the world population will soon be threatened by water supply problems, as mountain glaciers and alpine lakes are endangered by progressive global warming and by the increase of demand due to population growth.

    This veritable natural tragedy is unfolding not only in the Himalayas, but also in Europe and the United States, places not usually believed to be dependent on mountains for people and economics.

    Research says 1,9 billion people and half of biodiversity-prone areas around the world could suffer from the decline of natural mountain water supplies, which store water in the winter and slowly release it during the summer. . According to scientists

    Climate change threatens the entire mountain ecosystem, immediate action is needed to safeguard the future of the world's most important and vulnerable water resources

    International action to reduce carbon emissions may also be the best way to safeguard mountain water resources. In fact, if the Paris Agreements, a global action plan to contain climate change and limit global warming to 1,5 ° C, were respected, 75% of high-altitude snow and ice would not be damaged. On the contrary, if countries do not respect the pacts, 80% of this enormous heritage would be lost by 2100.

    The very serious damage is not limited only to the water resources of mountain ecosystems: the excessive exploitation of fresh water resources can also jeopardize the food safety. Furthermore, if adequate measures are not taken as soon as possible, keeping water consumption at sustainable levels in the near future could become even more difficult.
