Arid Dune Ecosystems: The Nizzana Sands in the Negev Desert
Sand dune dynamics plays a key role in many arid deserts. This volume provides a synthesis of a specific sand dune ecosystem, the Nizzana site in the Negev Desert. Describing its climate and geophysical/geochemical properties of soils, geological history, flora and fauna, and past/present land-use patterns, it elucidates ecological and geomorphological processes and their interrelations, based on long-term monitoring, in situ experiments and satellite imagery. Particular attention is drawn to the impact of the topsoil biological crust in controlling water availability at local/regional scales. The interdisciplinary approach adopted in this case study offers a good example of a highly complex and dynamic system, which could easily be applied to other sandy ecosystems.
Arabian Deserts : Nature, origin and evolution
This is the first comprehensive survey of all the deserts of Arabia, based largely on the author's 50 years of experience there. The text deals with every kind of desert in the region, from vast sand seas to clay pans and stony plains to volcanic flows.
Agroforestry in Europe : Current Status and Future Prospects
Brings together some of the most important current research in European agroforestry, and evaluates the current scope and future potential of agroforestry across the EU.While the majority of Europe’s agroforestry practices are currently focused in the Mediterranean, this volume draws together examples from a wide range of countries – including Greece, Spain, the UK, Hungary, Germany, Italy, the Netherlands, Switzerland, France and Slovenia. The book also covers a range of agroforestry types, including silvopastoralism – Europe’s predominant form of agroforestry – as well as alley cropping, forest farming, silvoarable systems and the use of trees for shelter. Through these examples the book also discusses the potential roles for these traditional land management systems in addressing both environmental issues such as water quality, biodiversity conservation, desertification, ecosystem services and socioeconomic issues such as rural population stabilization.
Advancing Quality of Life in a Turbulent World
Environmental issues continued to loom large in the last decade of the twentieth century,especially environmental problems related to rising levels of CO emissions and 2 other greenhouse gases on the planet’s average temperatures and, subsequently, storm patterns. Floods and droughts, in combination with unseasonably high and low temperatures became the norm rather than the exception for large expanses of Africa,Asia and Oceania. Even large areas of Europe and NorthAmerica were s- jected to recurrent floods and droughts and experienced unseasonable extremes of hot and cold temperatures associated with man-made intrusions into the natural environment. And, still, a global plan of action to haltman-related patterns of def- estation, desertification, and over-fishing of the seas has yet to come into being. At the same time, the number of regional conflicts and civil wars increased and, with them, the lives of many women, children, old people and other n- combatants were lost in these conflicts.
