The Mediterranean has been subject to changing human settlement and land use patterns for millennia, and has a history of human exploitation in an inherently unstable landscape. Environmental Issues in the Mediterranean reviews both physical and soci

This paper reviews recent work in the fields of ecology and economic ecology that contribute to a better understanding of the grazing and erosion debate. The approach is through dynamical systems models represented by differential equations and expre

Grazing is still widely held responsible for land degradation. The interaction between grazing and erosion is still rather poorly understood. As a consequence, counter-measures and associated management techniques have been slow to develop in souther

This paper argues for the replacement of the carrying capacity approach with an approach that emphasizes the stability conditions of the erosion–vegetation–grazing system. Using digital simulation, it is shown that the vegetation stability (tempo

What is overgrazing? Does it cause soil erosion? The recent debate from the ecological literature is reviewed as background to the debate on overgrazing and soil erosion. This debate stresses the need to view dryland grazing systems as dynamic ecosys

Two novel soil erosion models have been developed within the MEDALUS projects. Their principal innovation lies in the explicit treatment of long-term interactions with the vegetation and soil, with implications for the way in which the surface flow a

Within geography, physical geography is concerned with the characteristics of the natural environment, the atmosphere, the lithosphere and the biosphere; how they influence human activities and how they are affected by them across the face of the glo

The hydrological cycle is the movement of water from the atmosphere, through the soils and rocks, into river channels and to the sea. An important part of this cycle is the atmosphere and that is dealt with by Meentemeyer in Chapter 4 of this book. I
