Beschreibung:

The arid ecosystem has been under constant pressure of biotic and abiotic stresses all through the millennium. In the last few decades there has been acute resource depletion of the already fragile ecosystem through over-exploitation of resources by the ever expanding human and livestock populations and developmental activities. Realising the alarming situation, efforts were initiated a few decades ago by various national, regional and international organisations to contain the degradation processes and to restore to the productivity levels in the arid ecosystem. Researches in this direction have taken great strides. The degradation processes are now understood much better and monitoring has been made possible, thanks to the modern tools at the hands of the researchers. There has been a shift in the concept, from production capacity to sustainability of the production systems. Much advances have been made in last couple of decades to take stock of the recent advances in the field. The AZRAI organised a symposium on "Recent Advances in Management of Arid Ecosystem", in March 1997, over 300 participants attended the symposium. For the benefit of those who could not attend the symposia, the 200 papers presented, 125 have been published in this book after they were peer reviewed. The articles are grouped in seven major themes : (1) Natural resources apprasial, (2) Biodiversity and environmental conservation, (3) Sustainable crop production, (4) Alternate land use systems, (5) Optimal water use, (6) Socio-economic factors, and (7) Transfer of technology. The book gives a broad but in depth and up-to-date coverage to problems related to arid zones. It is hoped researchers, and planners will find the book interesting and useful.

Buchbeschreibung Springer-Verlag Gmbh Jan 2016, 2016. Buch. Buchzustand: Neu. Neuware - Invasions by exotic grasses, particularly annuals, rank among the most extensive and intensive ways that humans are contributing to the transformation of the earth's surface. The problem is particularly notable with a suite of exotic grasses in the Bromus genus in the arid and semiarid regions that dominate the western United States, which extend from the dry basins near the Sierra and Cascade Ranges across the Intermountain Region and Rockies to about 105° longitude. This genus includes approximately 150 species that have a wide range of invasive and non-invasive tendencies in their home ranges and in North America. Bromus species that became invasive upon introduction to North America in the late 1800's, such as Bromus tectorum and B. rubens, have since became the dominant cover on millions of hectares. Here, millenia of ecosystem development led to landscapes that would otherwise be dominated by perennial shrubs, herbs, and biotic soil crusts that were able to persist in spite of variable and scarce precipitation. This native ecosystem resilience is increasingly coveted by land owners and managers as more hectares lose their resistance to Bromus grasses and similar exotics and as climate, land use, and disturbance-regime changes are also superimposed. Managers are increasingly challenged to glean basic services from these ecosystems as they become invaded. Exotic annual grasses reduce wildlife and livestock carrying capacity and increase the frequency and extent of wildfi res and associated soil erosion. This book uses a unique ecoregional and multidisciplinary approach to evaluate the invasiveness, impacts, and management of the large Bromus genus. Students, researchers, and practitioners interested in Bromus specifically and invasive exotics in general will benefit from the depth of knowledge summarized in the book. 475 pp. Englisch.
