Quotations on Desertification Erosion, desertification, and pollution have become our lot. It is a weird form of suicide, for we are bleeding our planet to death. Gerald Durrell (1925-1995) was a British naturalist, zookeeper, conservationist and author. *** We already have the statistics for the future: the growth percentages of pollution, overpopulation, desertification. The future is already in place. Gunther Grass (1927- 2015) was a German novelist, poet, playwright, sculptor, and recipient of the Nobel Prize in Literature. *** Drought does not have to become famine. Too often the international community reacts too late. Too often decisions are taken based on false economies. In the end, we count the cost not just in human lives but in the extra expense of responding to crises that could have been averted for a fraction of the price. The world’s drylands are too often an investment desert, seen by governments and the international community as a lost cause. Ban Ki-moon (1944--) is a South Korean diplomat. *** “Increased aridity is making the drylands the most conflict prone region of the world,” Gnacadja (1958--) a former environment minister in Benin. *** Combating desertification and soil degradation requires better land management, better equipment and new technology to manage water, drought resistant seeds and payment to communities for preserving the soil. Gnacadja (1958--) a former environment minister in Benin. *** “If not prevented, desertification of the world can one day make the camels as the best and the sole cars of our civilisation!” Mehmet Murat ildan (1965--) is a Turkish playwright and writer. *** There have always been tensions and conflicts between agricultural and pastoral practices but desertification has accentuated them.
