Desertification

Beschreibung

Controversial, and often discussed with passion and vehemence, desertification is a problem on whose solution the survival of millions of humans is dependent. This book aims at an understanding of what is commonly called "desertification" - a term which has a connotation of irreversibility, spreading and emergence of desert-like landscapes: "land degradation" is proposed to replace it. The purpose is to present what has happened in reality, and what might be done. Illustrative worldwide analyses allow a more realistic evaluation of global land degradation. Each level of technology, excessive or insufficient, creates its own mismanagement. This is reflected in a decrease in soil productivity and eventually land degradation. The benefit to the reader is an awareness of the ecozones which have undergone the most severe land degradation, and a global overview of the phenomena, mechanisms and existing solutions.
To answer questions about the origin of desertification, a worldwide analysis of the phenomena was conducted. The processes leading to soil degradation and desertification, the prevention and remedies were systematically evaluated to overcome climate risks, to avoid threat to vegetation, to improve dryland agriculture, water conservation measures and maintainance of soil quality (water and wind erosion control).
