El gobierno estadounidense predice que para el 2025 el 60% de la masa total de tierra y 40 de nuestros 50 estados norteamericanos, experimentaran deficiencias de agua, algunos de carácter extremo. La salvación proviene de un lugar poco común, un país en medio del desierto. Ese país es Israel.
The water in oceans and seas cover 70 percent of the Earth’s surface.
They contain about 1.35 billion cubic kilometers (324 million cubic miles) of water, which is about 97 percent of all the water on Earth.
In the increasingly turbulent world of the Anthropocene, water is not only a victim of social-ecological change.
It is a key regulator of stable landscapes, biomes and Earth system (what we define as water resilience).
Furthermore, even though the great acceleration of anthropogenic global change started already in the mid 1950s, we may only now be at the beginning of truly rapid and large changes.
• The first is the risk that increasing human pressures on the Earth’s lifesupport systems may result in abrupt, irreversible and large-scale changes, undermining the ability of the biosphere to support human development. Water plays a central role in this context.
• The second is the increasing social momentum in a world that has only recently started to ‘move to scale’ in terms of human demands for natural capital, including water; as the number of poor rapidly reduces and the proportion of ‘middle class citizens’ rises from a few billion to the majority of a world’s projected nine billion population by 2050.
If left unmanaged, the potential implications for global freshwater resources are staggering.
