Aridification

Man made climate change and local policies increase speed of aridification (Link). It is not only the Sahara desert that is spreading out, but the lake Aral is another horrible example of the disrespect mankind attributes to its own resources of living. As more regions become arid due to our faults and long term consequences of industrialization we provoke human resettlement of an increasing scale. Water resources are and have been for centuries the major reason for people to settle nearby. Aridification of the soil like in California increases the risks of wild fires. The costs associated with aridification are very high and such areas can no longer be insured through normal private insurers. In most cases poor people or countries are affected the most, but we are all likely to bear the consequences in one way or another. We will have to accept that the size of habitable areas on earth decreases while the peek demography of humans is still at least a decade away from now. Not to tackle aridification is not an option. When shall we ever learn? (Image: sketch for Hagar and Ishmael in the desert, by Navez 1819, MRBAB)
