Landscape Ecological Applications in Man-Influenced Areas : Linking Man and Nature Systems
This book also includes several case studies concerning landscape analysis and evaluation using spatial analysis and landscape modelling for establishing sustainable management strategy in urban and agricultural landscapes. The subtitle of the book suggests the integrative and ubiquitous landscape planning considering harmony of man and nature systems in the socio-economic and cultural background.
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.
Location, Transport and Land-Use : Modelling Spatial-Temporal Information
Shows the use of statistical tools for forecasting and analyzing implications of land-use decisions. The idea is that la- use on a map is necessarily a consequence of individual, and often conflicting, siting decisions over time.
Land-Use and Land-Cover Change : Local Processes and Global Impacts
The book presents recent estimates of the rates in changes of major land classes such as forest, cropland and pasture. Among the causative mechanisms behind land change, synergetic factor combinations are found to be more common than single key factor explanations. Aggregated globally, multiple impacts of local land changes are shown to significantly affect central aspects of Earth System functioning. Innovative developments and applications in the fields of modeling and scenario construction are presented. Finally, conclusions are drawn about the most pressing implications for the design of appropriate intervention policies, and on new directions and frontiers of research.
Land Use and Soil Resources
Land-use change is one of the main drivers of many environmental change processes. It influences the basic resources of land use, including the soil. Its impact on soil often occurs so creepingly that land managers hardly contemplate initiating ameliorative or counterbalance measures. Poor land management has degraded vast amounts of land, reduced our ability to produce enough food, and is a major threat to rural livelihoods in many developing countries. To date, there has been no single unifying volume that addresses the multifaceted impacts of land use on soils. This book has responded to this challenge by bringing together renowned academics and policy experts to analyze the patterns, driving factors and proximate causes, and the socioeconomic impacts of soil degradation. Policy measures to prevent irreversible degradation and rehabilitate degraded soils are also identified.
Climate Change Impacts for the Conterminous USA : An Integrated Assessment
In this volume, an improved Integrated Assessment methodology is used to analyse climate change impacts on agriculture, water resources, unmanaged ecosystems, irrigation, and land use in the United States and the economic implications of these impacts. This book contains a series of papers documenting the methods, models, analysis and results of this integrated assessment for a wide ranging set of scenarios describing future climate change. Innovations described include the integration of water resource and agricultural modeling and the refinement of an agriculture and land-use economics model to incorporate results from process-level ecosystem models of agriculture, water and natural ecosystem resources. Scenarios selected for this study address a range of uncertainties associated with choice of climate model, presence or absence of a ‘CO2-fertilization effect’, impacts on international trade in agricultural commodities and their consequences for producers and consumers.
