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 Symbiotic Nitrogen Fixation by : P. Graham
Download or read book Symbiotic Nitrogen Fixation written by P. Graham and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 206 pages. Available in PDF, EPUB and Kindle. Book excerpt: During the past three decades there has been a large amount of research on biological nitrogen fixation, in part stimulated by increasing world prices of nitrogen-containing fertilizers and environmental concerns. In the last several years, research on plant--microbe interactions, and symbiotic and asymbiotic nitrogen fixation has become truly interdisciplinary in nature, stimulated to some degree by the use of modern genetic techniques. These methodologies have allowed us to make detailed analyses of plant and bacterial genes involved in symbiotic processes and to follow the growth and persistence of the root-nodule bacteria and free-living nitrogen-fixing bacteria in soils. Through the efforts of a large number of researchers we now have a better understanding of the ecology of rhizobia, environmental parameters affecting the infection and nodulation process, the nature of specificity, the biochemistry of host plants and microsymbionts, and chemical signalling between symbiotic partners. This volume gives a summary of current research efforts and knowledge in the field of biological nitrogen fixation. Since the research field is diverse in nature, this book presents a collection of papers in the major research area of physiology and metabolism, genetics, evolution, taxonomy, ecology, and international programs.

Book Synopsis Resources Use Efficiency in Agriculture by : Sandeep Kumar
Download or read book Resources Use Efficiency in Agriculture written by Sandeep Kumar and published by Springer Nature. This book was released on 2020-09-18 with total page 762 pages. Available in PDF, EPUB and Kindle. Book excerpt: Achieving zero hunger and food security is a top priority in the United Nations Development Goals (UNDGs). In an era characterized by high population growth and increasing pressure on agricultural systems, efficiency in the use of natural resources has become central to sustainable agricultural practices. Fundamentally speaking, eco-efficiency is about maximizing agricultural outputs, in terms of quantity and quality, using less land, water, nutrients, energy, labor, or capital. The concept of eco-efficiency involves both the ecological and economic aspects of sustainable agriculture. It is therefore essential to understand the interaction of ecosystem constituents within the extensive agricultural landscape, as well as farmers’ economic needs. This book examines the latest eco-efficient practices used in agro-systems. Drawing upon research and examples from around the world, it offers an up-to-date overview, together with insights into directly applicable approaches for poly-cropping systems and landscape-scale management to improve the stability of agricultural production systems, helping achieve food security. The book will be of interest to educators, researchers, climate change scientists, capacity builders and policymakers alike. It can also be used as additional reading material for undergraduate and graduate courses on agriculture, forestry, soil science, and the environmental sciences.

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 2000-08-17 with total page 422 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 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 Monitoring of Marine Pollution by : Houma Bachari Fouzia
Download or read book Monitoring of Marine Pollution written by Houma Bachari Fouzia and published by BoD – Books on Demand. This book was released on 2019-06-05 with total page 170 pages. Available in PDF, EPUB and Kindle. Book excerpt: Many of the pollutants discharged into the sea are directly or indirectly the result of human activities. Some of these substances are biodegradable, while others are not. This study is devoted to monitoring areas of the environment. Methods assessment is based on monitoring data and an evaluation of the impact of pollution.Surveillance provides a scientific basis for standards development and application. The methodology of marine pollution control is governed by algorithms and models. A monitoring strategy should be put in place, coupled with an environmental assessment concept, through targeted research activities in areas identified at local and regional levels. This concept will make it possible to diagnose the state of "health" of these zones and consequently to correct any anomalies. Monitoring of the marine and coastal environment is based on recent methods and validated after experiments in the field of marine pollution.

Book Synopsis Progress in Ecological Stoichiometry by : Dedmer B. Van de Waal
Download or read book Progress in Ecological Stoichiometry written by Dedmer B. Van de Waal and published by Frontiers Media SA. This book was released on 2018 with total page 382 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ecological stoichiometry concerns the way that the elemental composition of organisms shapes their ecology. It deals with the balance or imbalance of elemental ratios and how that affects organism growth, nutrient cycling, and the interactions with the biotic and abiotic worlds. The elemental composition of organisms is a set of constraints through which all the Earth’s biogeochemical cycles must pass. All organisms consume nutrients and acquire compounds from the environment proportional to their needs. Organismal elemental needs are determined in turn by the energy required to live and grow, the physical and chemical constraints of their environment, and their requirements for relatively large polymeric biomolecules such as RNA, DNA, lipids, and proteins, as well as for structural needs including stems, bones, shells, etc. These materials together constitute most of the biomass of living organisms. Although there may be little variability in elemental ratios of many of these biomolecules, changing the proportions of different biomolecules can have important effects on organismal elemental composition. Consequently, the variation in elemental composition both within and across organisms can be tremendous, which has important implications for Earth’s biogeochemical cycles. It has been over a decade since the publication of Sterner and Elser’s book, Ecological Stoichiometry (2002). In the intervening years, hundreds of papers on stoichiometric topics ranging from evolution and regulation of nutrient content in organisms, to the role of stoichiometry in populations, communities, ecosystems and global biogeochemical dynamics have been published. Here, we present a collection of contributions from the broad scientific community to highlight recent insights in the field of Ecological Stoichiometry.
