Available in PDF, EPUB and Kindle. Book excerpt: Presenting the first continental-scale assessment of reactive nitrogen in the environment, this book sets the related environmental problems in context by providing a multidisciplinary introduction to the nitrogen cycle processes. Issues of upscaling from farm plot and city to national and continental scales are addressed in detail with emphasis on opportunities for better management at local to global levels. The five key societal threats posed by reactive nitrogen are assessed, providing a framework for joined-up management of the nitrogen cycle in Europe, including the first cost-benefit analysis for different reactive nitrogen forms and future scenarios. Incorporating comprehensive maps, a handy technical synopsis and a summary for policy makers, this landmark volume is an essential reference for academic researchers across a wide range of disciplines, as well as stakeholders and policy makers. It is also a valuable tool in communicating the key environmental issues and future challenges to the wider public.
Book Synopsis Dynamics of Nutrient Cycling and Food Webs by : Donald L. DeAngelis
Download or read book Dynamics of Nutrient Cycling and Food Webs written by Donald L. DeAngelis and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 285 pages. Available in PDF, EPUB and Kindle. Book excerpt: In all fields of science today, data are collected and theories are developed and published faster than scientists can keep up with, let alone thoroughly digest. In ecology the fact that practitioners tend to be divided between such subdisciplines as aquatic and terrestrial ecology, as well as between popula tion, community, and ecosystem ecology, makes it even harder for them to keep up with all relevant research. Ecologists specializing in one sub discipline are not always aware of progress in another subdiscipline that relates to their own. Syntheses are frequently needed that pull together large bodies of information and organize them in ways that makes them more coherent, and thus more understandable. I have tried to perform this task of integration for the subject area that encompasses the interrelationships between the dynamics of ecological food webs and the cycling of nutrients. I believe this area cuts across many of the subdisciplines of ecology and is pivotal to our progress in understanding ecosystems and in dealing with human impacts on the environment. Many current ecological problems involve human disturbances of both food webs and the nutrients that cycle through them. Little progress can be made towards elucidating the complex feedback relations inherent in the study of nutrient cycles in ecological systems without the tools of mathematics and computer modelling. These tools are therefore liberally used throughout the book.
Book Synopsis Carbon and Nitrogen Cycling in European Forest Ecosystems by : Ernst-Detlef Schulze

This book was released on 2013-12-01 with total page 520 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume quantifies carbon storage in managed forest ecosystems not only in biomass, but also in all soil compartments. It investigates the interaction between the carbon and nitrogen cycles by working along a north-south transect through Europe that starts in northern Sweden, passes through a N-deposition maximum in central Europe and ends in Italy. For the first time biogeochemical processes are linked to biodiversity on a large geographic scale and with special focus on soil organisms. The accompanying CD-ROM provides a complete database of all flux, storage and species observations for modellers.
Book Synopsis Riverine Ecosystem Management by : Stefan Schmutz
Download or read book Riverine Ecosystem Management written by Stefan Schmutz and published by Springer. This book was released on 2018-05-08 with total page 562 pages. Available in PDF, EPUB and Kindle. Book excerpt: This open access book surveys the frontier of scientific river research and provides examples to guide management towards a sustainable future of riverine ecosystems. Principal structures and functions of the biogeosphere of rivers are explained; key threats are identified, and effective solutions for restoration and mitigation are provided. Rivers are among the most threatened ecosystems of the world. They increasingly suffer from pollution, water abstraction, river channelisation and damming. Fundamental knowledge of ecosystem structure and function is necessary to understand how human acitivities interfere with natural processes and which interventions are feasible to rectify this. Modern water legislation strives for sustainable water resource management and protection of important habitats and species. However, decision makers would benefit from more profound understanding of ecosystem degradation processes and of innovative methodologies and tools for efficient mitigation and restoration. The book provides best-practice examples of sustainable river management from on-site studies, European-wide analyses and case studies from other parts of the world. This book will be of interest to researchers in the field of aquatic ecology, river system functioning, conservation and restoration, to postgraduate students, to institutions involved in water management, and to water related industries.
Book Synopsis Clean Coastal Waters by : National Research Council
Download or read book Clean Coastal Waters written by National Research Council and published by National Academies Press. This book was released on 2000-07-17 with total page 421 pages. Available in PDF, EPUB and Kindle. Book excerpt: Environmental problems in coastal ecosystems can sometimes be attributed to excess nutrients flowing from upstream watersheds into estuarine settings. This nutrient over-enrichment can result in toxic algal blooms, shellfish poisoning, coral reef destruction, and other harmful outcomes. All U.S. coasts show signs of nutrient over-enrichment, and scientists predict worsening problems in the years ahead. Clean Coastal Waters explains technical aspects of nutrient over-enrichment and proposes both immediate local action by coastal managers and a longer-term national strategy incorporating policy design, classification of affected sites, law and regulation, coordination, and communication. Highlighting the Gulf of Mexico's "Dead Zone," the Pfiesteria outbreak in a tributary of Chesapeake Bay, and other cases, the book explains how nutrients work in the environment, why nitrogen is important, how enrichment turns into over-enrichment, and why some environments are especially susceptible. Economic as well as ecological impacts are examined. In addressing abatement strategies, the committee discusses the importance of monitoring sites, developing useful models of over-enrichment, and setting water quality goals. The book also reviews voluntary programs, mandatory controls, tax incentives, and other policy options for reducing the flow of nutrients from agricultural operations and other sources.
Book Synopsis Climate Change, Air Pollution and Global Challenges by : Werner Eugster
Download or read book Climate Change, Air Pollution and Global Challenges written by Werner Eugster and published by Elsevier Inc. Chapters. This book was released on 2013-11-19 with total page 26 pages. Available in PDF, EPUB and Kindle. Book excerpt: Forests take up gaseous, liquid and particulate substances that are present in the air. Although considered nutrients on the one hand, nitrogen inputs exceeding the critical load that can be absorbed by an ecosystem act as pollutants. This chapter outlines the effects of N deposition to forest ecosystems and discusses recent progress that has been made to more accurately quantify dry deposition, which at many a forest location in Europe is larger than wet and occult deposition. To quantify the effects of N deposition on tree growth, a good measure for net ecosystem production (NEP) is needed. Eddy covariance (EC) flux measurements are one established way to quantify NEP. While EC flux measurements are costly and remain restricted in their application to a few suitable locations, dendrometer measurements with high temporal resolution show a similar seasonal and annual signal to NEP. Such measurements are becoming increasingly important to quantify ecosystem biomass accumulation, which can be related to N deposition rates. The policy relevance of such activities emerges from the UNECE's Gothenburg protocol to abate acidification, eutrophication and ground-level ozone, but also the quantification of natural sinks under the Kyoto protocol profits from such measurements.
Book Synopsis Eutrophication: causes, consequences and control by : Abid A. Ansari
Download or read book Eutrophication: causes, consequences and control written by Abid A. Ansari and published by Springer Science & Business Media. This book was released on 2010-10-17 with total page 402 pages. Available in PDF, EPUB and Kindle. Book excerpt: Eutrophication continues to be a major global challenge to water quality scientists. The global demand on water resources due to population increases, economic development, and emerging energy development schemes has created new environmental challenges to global sustainability. Eutrophication, causes, consequences, and control provides a current account of many important aspects of the processes of natural and accelerated eutrophication in major aquatic ecosystems around the world. The connections between accelerated eutrophication and climate change, chemical contamination of surface waters, and major environmental and ecological impacts on aquatic ecosystems are discussed. Water quality changes typical of eutrophication events in major climate zones including temperate, tropical, subtropical, and arid regions are included along with current approaches to treat and control increased eutrophication around the world. The book provides many useful new insights to address the challenges of global increases in eutrophication and the increasing threats to biodiversity and water quality.
Book Synopsis Source Apportionment of Nitrogen and Phosphorus Inputs Into the Aquatic Environment by : European Environment Agency
Download or read book Source Apportionment of Nitrogen and Phosphorus Inputs Into the Aquatic Environment written by European Environment Agency and published by . This book was released on 2005 with total page 54 pages. Available in PDF, EPUB and Kindle. Book excerpt: Eutrophication, the excessive enrichment of waters with nutrients and the associated adverse biological effects, is one of the major environmental problems across Europe. European waters are affected across the whole range from inland water bodies such as groundwater, rivers and lakes, to transitional and coastal waters and ecosystems in open seas. Eutrophication is caused by large anthropogenic inputs of the nutrients nitrogen (N) and phosphorus (P) to the aquatic environment from a range of societal sectors. This study primarily focuses on the contribution of agriculture to this contamination.
Book Synopsis Sensitivity of the North Sea Ecosystem to a Combined Reduction of Phosphorus and Nitrogen Loads by :
Download or read book Sensitivity of the North Sea Ecosystem to a Combined Reduction of Phosphorus and Nitrogen Loads written by and published by . This book was released on 2023 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Greater North Sea is a semi enclosed basin, situated on the continental shelf of north-west Europe. Its Southern part is very prone to eutrophication, as it receives most of the run-offs and is relatively isolated from the direct influence of the Atlantic waters. We aim here to assess the impact of a reduction in nitrogen and phosphorus loads originating from coastal discharges by performing numerical modelling experiments. The configuration used is the 5km ocean model GETM (General Estuarine Transport Model) coupled with ERSEM (European Regional Seas Ecosystem Model). The GREEN (Geospatial Regression Equation for European Nutrient losses) hydrological model provided nutrients loads. After a 30 years spinup, 16 sensitivity experiments have been integrated from 2010 to 2015. The nitrogen and phosphorus discharges have been independently set to 20, 50, 80 and 100 % of the original nutrient load. We analysed the mean levels of several criteria of the descriptor D5 related to Eutrophication. In particular we focus on D5C1 (nutrients), D5C2 (chlorophyll), D5C5 (bottom oxygen), and determined Good Environmental Status (GES) based on Threshold Values (TVs). Dissolved inorganic phosphate (DIP) presents a smaller sensitivity to a load decrease than Dissolved Inorganic Nitrogen (DIN). DIP decreases by 18 % when total phosphorus loads decreases by a factor 2 while DIN decreases by 36 % when total nitrogen decreases by a factor 2. Chlorophyll decreases by 4 %. DIN and DIP reduction have to be performed simultaneously to maintain the DIN:DIP ratio to a constant value, which is important for an healthy ecosystem functioning.

Book Synopsis Nutrient Cycling in Forest Ecosystems by : Robert G. Qualls
Download or read book Nutrient Cycling in Forest Ecosystems written by Robert G. Qualls and published by MDPI. This book was released on 2020-12-03 with total page 218 pages. Available in PDF, EPUB and Kindle. Book excerpt: The long-term productivity of forest ecosystems depends on the cycling of nutrients. The effect of carbon dioxide fertilization on forest productivity may ultimately be limited by the rate of nutrient cycling. Contemporary and future disturbances such as climatic warming, N-deposition, deforestation, short rotation sylviculture, fire (both wild and controlled), and the invasion of exotic species all place strains on the integrity of ecosystem nutrient cycling. Global differences in climate, soils, and species make it difficult to extrapolate even a single important study worldwide. Despite advances in the understanding of nutrient cycling and carbon production in forests, many questions remain. The chapters in this volume reflect many contemporary research priorities. The thirteen studies in this volume are arranged in the following subject groups: • N and P resorption from foliage worldwide, along chronosequences and along elevation gradients; • Litter production and decomposition; • N and P stoichiometry as affected by N deposition, geographic gradients, species changes, and ecosystem restoration; • Effects of N and P addition on understory biomass, litter, and soil; • Effects of burning on soil nutrients; • Effects of N addition on soil fauna.
Book Synopsis Managing Energy, Nutrients, and Pests in Organic Field Crops by : Ralph C. Martin
Download or read book Managing Energy, Nutrients, and Pests in Organic Field Crops written by Ralph C. Martin and published by CRC Press. This book was released on 2014-02-07 with total page 438 pages. Available in PDF, EPUB and Kindle. Book excerpt: The use of organic management practices in field cropping continues to rise globally, and these methods have proven to be a viable way to produce food with reduced resource use and environmental damage. Managing Energy, Nutrients, and Pests in Organic Field Crops challenges the popular misconception that organic systems are weak at managing energy, nutrients, and pests and shows how innovative farm designs can enhance organic performance. It provides information for assessing the current state of knowledge on organic field cropping and for making the systems more viable. Each chapter summarizes the latest data from a wide range of sources, creating a comprehensive and coherent picture of the issues and integrating agronomic, economic, and policy aspects. Many chapters also include recent research from the authors. Section I, Soil Health, examines the importance of phosphorus balance, soil fertility, and tillage reduction. Section II, Pest Management, focuses on integrated weed management and long-term approaches to insect management. Section III, Integrating Approaches, addresses multiple field cropping challenges. Chapters cover the oldest organic rotational trials in Canada, the issue of using cereals bred for conventional systems and more targeted organic cereal breeding strategies, and case studies of a broad spectrum of farming experiences that explore the broader social and ecological landscape. The final section, Economics, Energy, and Policy, examines environmental issues not previously addressed in the text as well as consumer, economic, and rural community matters. It also presents a reprint of an article that describes policies and programs (and their costs) needed to advance adoption of organic farming in Ontario. The text wraps up with key conclusions and a discussion of overarching themes for the book, summarizing the strengths of the available tool box for organic producers and the challenges that remain.
