Download or read book Vegetation Water Humans and the Climate written by Pavel Kabat and published by Springer Science & Business Media. 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 Global Change and the Terrestrial Biosphere written by H. H. Shugart and published by John Wiley & Sons. This book was released on 2011-06-13 with total page 288 pages. Available in PDF, EPUB and Kindle. Book excerpt: Global climate change challenges ecologists to synthesize what we know to solve a problem with deep historical roots in our discipline. In ecology, the question, “How do terrestrial ecosystems interact with the other earth systems to produce planetary change?” has sufficient depth to be the focal challenge. This central question is sharpened further as the changes that we may be manifesting upon our planet’s systems of land, sea, air and ice can have potential consequences for the future of human civilization. This book provides the depth of the history of global ecology and reviews the breadth of the ideas being studied today. Each chapter starts with a brief narrative about a scientist whose work traces forward into today’s issues in global ecosystems. The discussions are framed in a growing realization that we may be altering the way our planet functions almost before we have gained the necessary knowledge of how it works at all.
Download or read book Modeling Carbon Fluxes Net Primary Production and Light Utilization in Boreal Forest Stands written by Scott J. Goetz and published by Universal-Publishers. This book was released on 1997-08 with total page 136 pages. Available in PDF, EPUB and Kindle. Book excerpt: The use of satellite remote sensing for modeling net primary production (NPP) was evaluated in sixty boreal forest stands spanning a range of site conditions. The work included: (i) estimating annual phenological dynamics and photosynthetically active radiation (PAR) interception with remotely sensed spectral measurements, (ii) linking annually absorbed PAR (APAR) to measured NPP and quantifying variability in light use efficiency ("En"), (iii) evaluating sources of variability in "En" via mechanistic modeling of ecophysiology and associated carbon fluxes, particularly through analyses of respiratory carbon costs in relation to assimilation gains (the R: A ratio), (iv) assessing generalization of the results through an investigation of the evidence for evolutionary convergence in "En", the R: A ratio and assimilation per unit APAR (Eg). The analyses showed that observed variability in "En" reflects a decoupling of PAR harvesting and utilization, primarily as a result of differences in the R: A ratio. Links between "En", the R: A ratio and standing above-ground biomass were related to differences the carbon (energy) costs associated with synthesis and maintenance of plant constituents, and longevity (i.e. the payback period on investment in carbon gain). Estimating the R: A ratio from above-ground biomass, in order to compensate for variability in "En", was found to be problematic owing primarily to covariation of R and A with the amount of respiring biomass (i.e. sapwood and foliage). The analyses also showed that the differences in carbon costs between functional types (plants with related life history traits) resulted in convergence on "Eg" rather than en. Variability in "Eg" was, however, introduced by stomatal control at some stressed sites. These findings were supported by the remote sensing and simulation modeling results, and the synthesis of work related to evolutionary ecology. The primary conclusions are that variability in light utilization in these boreal forest stands was determined largely by respiratory carbon costs, and that NPP models based on light harvesting require augmentation with terms that reflect PAR utilization. Possible methods to address these issues, and their implications for NPP modeling over large areas, are discussed.
Download or read book Boreal Forests in the Face of Climate Change written by Miguel Montoro Girona and published by Springer Nature. This book was released on 2023-03-01 with total page 859 pages. Available in PDF, EPUB and Kindle. Book excerpt: This open access book explores a new conceptual framework for the sustainable management of the boreal forest in the face of climate change. The boreal forest is the second-largest terrestrial biome on Earth and covers a 14 million km2 belt, representing about 25% of the Earth’s forest area. Two-thirds of this forest biome is managed and supplies 37% of global wood production. These forests also provide a range of natural resources and ecosystem services essential to humanity. However, climate change is altering species distributions, natural disturbance regimes, and forest ecosystem structure and functioning. Although sustainable management is the main goal across the boreal biome, a novel framework is required to adapt forest strategies and practices to climate change. This collaborative effort draws upon 148 authors in summarizing the sustainable management of these forests and detailing the most recent experimental and observational results collected from across the boreal biome. It presents the state of sustainable management in boreal forests and highlights the critical importance of this biome in a context of global change because of these forests' key role in a range of natural processes, including carbon sequestration, nutrient cycling, and the maintaining of biodiversity. This book is an essential read for academics, students, and practitioners involved in boreal forest management. It outlines the challenges facing sustainable boreal forest management within the context of climate change and serves as a basis for establishing new research avenues, identifying future research trends, and developing climate-adapted forest management plans.

Several applications are presented, where a focus is on cases where the hydrological cycle plays a central role.
Download or read book Environmental Modelling and Prediction written by Gongbing Peng and published by Springer Science & Business Media. This book was released on 2013-03-09 with total page 487 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this book the authors consider the natural environment as an integrated system. The physical, chemical and biological processes that govern the behaviour of the environmental system can thus be understood through mathematical modelling, and their evolution can be studied by means of numerical simulation. The book contains a summary of various efficient approaches in atmospheric prediction, such as numerical weather prediction and statistical forecast of climate change, as well as other successful methods in land surface modelling. The authors explore new theories and methods in environment prediction such as systems analysis and information theory. Attention is given to new achievements in remote sensing tele-metering and geographic information systems.

Available in PDF, EPUB and Kindle. Book excerpt: Forest landscape disturbances are a global phenomenon. Simulation models are an important tool in understanding these broad scale processes and exploring their effects on forest ecosystems. This book contains a collection of insights from a group of ecologists who address a variety of processes: physical disturbances such as drought, wind, and fire; biological disturbances such as defoliating insects and bark beetles; anthropogenic influences; interactions among disturbances; effects of climate change on disturbances; and the recovery of forest landscapes from disturbances—all from a simulation modeling perspective. These discussions and examples offer a broad synopsis of the state of this rapidly evolving subject.

This book was released on 2009-04-20 with total page 269 pages. Available in PDF, EPUB and Kindle. Book excerpt: Strong atmosphere-hydrology-biosphere feedbacks including human activity affect the rate and sign of changes in the Earth’s system and have impacts on socioeconomic relationships. These processes are related to atmospheric circulation, climate and land use changes. Satellite-based and in situ monitoring systems have greatly increased our understanding of variations and changes occurring in the regional climate, atmospheric regime, land cover and water circulation. Coupled numerical models are invoked to describe features, which cannot be caught by observation systems or to predict a future state. This book summarizes the state-of-the-art researches on land cover, atmosphere and water resources of the Eastern Europe region, sets up priorities of major researches in these fields, outlines deficiencies in data and their processing, and develops recommendations for further research directions. Selected papers of the Non-Boreal Eastern Europe NEESPI meeting cover five topics: Observational issues in the non-boreal Eastern Europe Regional climate changes Air pollution aspects Land cover and land use changes Changes in the Black Sea and its coastal zone.

Available in PDF, EPUB and Kindle. Book excerpt: The Forest Primary Production Research Group was born in the Department of S- viculture, University of Helsinki in the early 1970s. Intensive ?eld measurements of photosynthesis and growth of forest vegetation and use of dynamic models in the interpretation of the results were characteristic of the research in the group. Electric instrumentation was based on analogue techniques and the analysis of the obtained measurements was based on self-written programs. Joint research projects with the Research Group of Environmental Physics at the Department of Physics, lead by Taisto Raunemaa (1939–2006) started in the late 1970s. The two research groups shared the same quantitative methodology, which made the co-operation fruitful. Since 1980 until the collapse of the Soviet Union the Academy of Finland and the Soviet Academy of Sciences had a co-operation program which included our team. The research groups in Tartu, Estonia, lead by Juhan Ross (1925–2002) and in Petrozawodsk, lead by Leo Kaipiainen (1932–2004) were involved on the Soviet side. We had annual ?eld measuring campaigns in Finland and in Soviet Union and research seminars. The main emphasis was on developing forest growth models. The research of Chernobyl fallout started a new era in the co-operation between forest ecologists and physicists in Helsinki. The importance of material ?uxes was realized and introduced explicitly in the theoretical thinking and measurements.
