The ecumene
is not only encroached by the sea level rise. The desertification is also an
important threat for the population. Far from saying that it is not possible to
settle the desert, the Gulf countries have showed us recently that towers do
not need rainfalls to grow, I mean that all the human activities are not
possible in the desert, especially, the most essential: agriculture. According
to the FAO, two millions ha of farmland and more than 4.9 million ha of
pastures are threatened by desertification. It is all the more unfortunate
because the population is increasing and the consummation per capita is increasing too. The
commercial farming extends its fields artificializing some natural ecosystems
and making them vulnerable. For example, in Brazil, the rainforest step back in
favor of the short term sugar cane plantations.
Some solutions exist against desertification.
I let you have a look to this video from Yan
Arthus Bertrand who introduces very well this threat and the solutions. Yan Arthus Bertrand is a French photographer who has observed many modifications in the landscapes over the last 30 years. He decided to sensibilize people one these questions and to lead them to sustainable behavior through his foundation Good Planet.
