Wüsten im Vormarsch - Season 1 (2007)

According to estimates of the United Nations, more than 2.6 billion people in 110 countries are directly affected by progressive desertification. Deserts now cover more than a third of the entire surface of the earth, thus 65% of arable lands. More than three billion cattle, sheep and goats chomp their way through pastures faster than they can be regenerated.
