Available in PDF, EPUB and Kindle. Book excerpt: Hardbound. Land-surface processes are essential to the understanding of climate. They are also critical to a better assessment of the availability of water resources and further, central to the description of the interactions between the climate and the biosphere.The HAPEX-Sahel programme was set up specifically in Niger to study these points.In the sub-sahelian region the rainy season is short, 3 months long, during which time the conditions vary from extreme dryness to a full bloom of natural and agricultural vegetation, followed by a rapid senescence. In other words the location of Niger for this research made it possible to document over a period of 3 months, processes that would have taken one full year to observe in a region of less extreme conditions.Now, after 9 years research, the variety of results collected during the HAPEX-Sahel programme are published in this book. The reader can discover, for example: - how spatial integra

This book was released on 2012-12-06 with total page 266 pages. Available in PDF, EPUB and Kindle. Book excerpt: Aerial photography has revealed the striking, widespread phenomenon of repeating patterns of vegetation in more arid areas of the world. Two interdependent phases, bands of dense and sparse vegetation, alternate in the landscape. This volume synthesizes half a century's accumulated knowledge of both theoretical and applied landscape function from a variety of these regions. It covers structure, dynamics, and methods of study, as well as disturbances to these landscapes and relevant management issues. Various chapters discuss the role of modeling in answering questions about the origins and complex processes of banded landscapes.

Available in PDF, EPUB and Kindle. Book excerpt: Hydrology is vital to human civilisations as well as to natural ecosystems, yet it has only emerged as a distinct scientific discipline during the last 50 years or so. This book reviews the development of modern hydrology primarily through the experiences of the multidisciplinary team of scientists and engineers at Wallingford, near Oxford, who have been at the forefront of many of the developments in UK hydrological research. These topics include: • The development of basic understanding through the collection of data with specialised instrumentation in experimental basins • The study of extreme flows – both floods and droughts • The role moisture in the soil • Studies of the processes controlling evaporation • Water resource studies • Modelling and prediction of the extremes of flow improved • Understanding of water quality issues • A widening recognition of the importance of an ecosystem approach • Meeting the challenges of climate change, • Data handling • Future developments in hydrology and the pressures which generate them. Readership: hydrologists in both academia and a wide range of applied fields such as civil engineering, meteorology, geography and physics, as well as advanced students in earth science, environmental science and physical geography programmes worldwide.

This book was released on 2012-12-06 with total page 565 pages. Available in PDF, EPUB and Kindle. Book excerpt: A state-of-the-art overview of the influence of terrestrial vegetation and soils within the Earth system. The text deals especially with interactions between the terrestrial biosphere and the atmosphere via the hydrological cycle and their interlinkage with anthropogenic activities. Measurements gathered in integrated field experiments in the Sahel, the Amazon, North America and South-east Asia confirm the importance of these interactions. Observations are complemented by modelling studies, including regional models that simulate flows and transport in river catchments, coupled land-cover and regional climate systems, and Earth-system and global circulation models. Water, nutrient and sediment fluxes in river basins are also discussed and are shown to be highly impacted and regulated by humans through land use, pollution and river engineering. Finally, the book discusses environmental vulnerability and methodologies for assessing the risks associated with regional and global climatic and environmental variability and change. The results reported in this book are based on the research work of many individual scientists and teams around the world associated with the objectives of the IGBP-BAHC and WCRP-GEWEX international research programmes.

Download or read book The End of Desertification? written by Roy H. Behnke and published by Springer. This book was released on 2016-04-12 with total page 556 pages. Available in PDF, EPUB and Kindle. Book excerpt: The question in the title of this book draws attention to the shortcomings of a concept that has become a political tool of global importance even as the scientific basis for its use grows weaker. The concept of desertification, it can be argued, has ceased to be analytically useful and distorts our understanding of social-environmental systems and their resiliency, particularly in poor countries with variable rainfall and persistent poverty. For better policy and governance, we need to reconsider the scientific justification for international attempts to combat desertification. Our exploration of these issues begins in the Sahel of West Africa, where a series of severe droughts at the end of the 20th century led to the global institutionalization of the idea of desertification. It now seems incontrovertible that these droughts were not caused primarily by local land use mismanagement, effectively terminating a long-standing policy and scientific debate. There is now an opportunity to treat this episode as an object lesson in the relationship between science, the formation of public opinion and international policy-making. Looking beyond the Sahel, the chapters in this book provide case studies from around the world that examine the use and relevance of the desertification concept. Despite an increasingly sophisticated understanding of dryland environments and societies, the uses now being made of the desertification concept in parts of Asia exhibit many of the shortcomings of earlier work done in Africa. It took scientists more than three decades to transform a perceived desertification crisis in the Sahel into a non-event. This book is an effort to critically examine that experience and accelerate the learning process in other parts of the world.

This book was released on 2013-03-14 with total page 228 pages. Available in PDF, EPUB and Kindle. Book excerpt: The interaction between environmental change and human activities is com plex, requiring the concepts and tools of a number of disciplines for its effective analysis. Land-use and land-cover change has only recently become a topic susceptible to scientific research, as these concepts and tools have been devel oped and made available. Rooted in a broad community concemed with global change, systematic research has begun into land-use systems at different scales and interactions, and their links with global cyc1es of water, nitrogen and carbon are being explored. Partly based on research initiated by the Dutch National Research Programme on Global Air PolIution and Climate Change (NRP), this book touches upon various land-use and land-cover issues in relation to global environmental change. In addition to the biogeochemical cyc1es, land as a car rier for functions of economic activities, food and fibre production and energy production via biomass are discussed. Crucial in studying land use is human behaviour and man-environment interaction at different scales. Land-use and land-cover change is an important contrlbutor of greenhouse gasses as these activities directly interfere with the carbon, nitrogen and water cyc1es. These cyc1es are connected through numerous feedback loops. The interface of land-use and c1imate is essentially determined by the interaction of man and the environment. Man uses land primarily to produce food; a relatively small area is needed for urban development.

Available in PDF, EPUB and Kindle. Book excerpt: Wildfires, changing glaciers, deforestation, open-pit mining, increasing demands for food and bio-fuel production and the growth of megacities change our landscape. The book comprehensively reviews the current knowledge on how natural and anthropogenic land-use/cover changes affect weather, air quality and climate worldwide and explains how these changes may trigger further land-use/cover changes. It discusses how anthropogenic land-use/cover changes have affected local and regional climate and air quality since the settlement of America and the industrialisation. It addresses the topic how long-range transport of pollutants and dust of devasted areas as well as teleconnections may cause changes far away from the areas where the land-use/cover changes occurred, for which land-use/cover change may become an international issue similar to CO2. It also discusses relations to global change and future societal and scientific challenges related to land-use/cover changes.

Download or read book Land Surface — Atmosphere Interactions for Climate Modeling written by E.F. Wood and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 302 pages. Available in PDF, EPUB and Kindle. Book excerpt: It is well known that the interactions between land surfaces and the atmosphere, and the resulting exchanges in water and energy have a tremendous affect on climate. The inadequate representation of land-atmosphere interactions is a major weakness in current climate models, and is providing the motivation for the HAPEX and ISLSCP experiments as well as the proposed Global Energy and Water Experiment (GEWEX) and the Earth Observing System (EOS) mission. The inadequate representation reflects the recognition that the well-known phys ical relationships, which are well described at small scales, result in different relationships when represented at the scales used in climate models. Understanding this transition in the mathematical relationships with increased space-time scales appears to be very difficult, and has led to different approaches; at one extreme, the famous "bucket" model where the land-surface is a simple one layer storage without vegetation; the other extreme may be Seller's Simple Biosphere Model (Sib) where one big leaf covers the climate model grid. Given the heterogeneous nature of landforms, soils and vegetation within a climate model grid, the development of new land surface parameterizations, and their verification through large scale experiments is perceived to be a challenging area of research for the hydrology and meteorology communities. This book evolved from a workshop held at Princeton University to explore the status of land surface parameterizations within climate models, and how observa tional data can be used to assess these parameterizations and improve models.
