Governing International Watercourses - River Basin Organizations and the Sustainable Governance of Internationally Shared... Governing International Watercourses - River Basin Organizations and the Sustainable Governance of Internationally Shared Rivers and Lakes (Paperback)
Susanne Schmeier
R1,717 Discovery Miles 17 170 Ships in 12 - 17 working days

This book focuses on River Basin Organizations as the key institutions for managing internationally shared water resources. This includes a comparative analysis of all River Basin Organizations worldwide and three in-depth case studies from three different continents. The detailed case studies are the Senegal (West Africa), Mekong (South-east Asia) and Danube (Europe) rivers. The book contributes to the academic debate on how shared natural and environmental resources can be managed in a sustainable way and which institutional and legal mechanisms actually matter for doing so. It adopts the neo-institutionalist approach, according to which international environmental institutions do make a difference. The analysis not only confirms this argument for the specific case of shared water resources, but also refines existing hypotheses on the influence of different independent variables, namely the nature of the collective action problem, the constellation of actors and the institutional design of an international environmental institution. The work also contributes to the policy debate on how to better govern internationally shared natural resources and the environment. It provides policy makers with advice on which exogenous conditions to be aware of when managing water resources they share with co-riparians and which institutional design features and governance mechanisms to set up in order to increase effectiveness in management.

R1,476 Discovery Miles 14 760 Ships in 12 - 17 working days

As the human population grows from seven billion toward an inevitable nine or 10 billion, the demands on the limited supply of soils will grow and intensify. Soils are essential for the sustenance of almost all plants and animals, including humans, but soils are virtually infinitely variable. Clays are the most reactive and interactive inorganic compounds in soils. Clays in soils often differ from pure clay minerals of geological origin. They provide a template for most of the reactive organic matter in soils. They directly affect plant nutrients, soil temperature and pH, aggregate sizes and strength, porosity and water-holding capacities. This book aims to help improve predictions of important properties of soils through a modern understanding of their highly reactive clay minerals as they are formed and occur in soils worldwide. It examines how clays occur in soils and the role of soil clays in disparate applications including plant nutrition, soil structure, and water-holding capacity, soil quality, soil shrinkage and swelling, carbon sequestration, pollution control and remediation, medicine, forensic investigation, and deciphering human and environmental histories. Features: Provides information on the conditions that lead to the formation of clay minerals in soils Distinguishes soil clays and types of clay minerals Describes clay mineral structures and their origins Describes occurrences and associations of clays in soil Details roles of clays in applications of soils Heavily illustrated with photos, diagrams, and electron micrographs Includes user-friendly description of a new method of identification To know soil clays is to enable their use toward achieving improvements in the management of soils for enhancing their performance in one or more of their three main functions of enabling plant growth, regulating water flow to plants, and buffering environmental changes. This book provides an easily-read and extensively-illustrated description of the nature, formation, identification, occurrence and associations, measurement, reactivities, and applications of clays in soils.

Soil Phosphorus (Paperback): Rattan Lal, B.A. Stewart Soil Phosphorus (Paperback)
Rattan Lal, B.A. Stewart
R1,487 Discovery Miles 14 870 Ships in 12 - 17 working days

Phosphorus is an essential plant nutrient, but global population growth has dramatically reduced the availability of phosphorus fertilizer resources. Despite this scarcity, there remain numerous problems associated with the excessive and inappropriate use of phosphorus leading to non-point source pollution and eutrophication of natural waters. Identifying appropriate systems for managing soil phosphorus and reducing the risks of eutrophication are needed to minimize the environmental risks. This book focuses on the availability and recycling of phosphorus; regulatory and policy issues of sustainable phosphorus use; and water quality management in agroecosystems pertaining to phosphorus. Sections are dedicated to global phosphorus reserves; cycling and pathways of phosphorus; phosphorus in agriculture; human dimensions and policy intervention; and research and development priorities. Phosphorus is a finite but crucial resource and is an essential element to all life. Sub-optimal availability and nutrient imbalance in the root zone can adversely impact plant growth, and the quality of food and feed grown on these soils. However, the proven reserves of phosphorus can hardly be adequate for a few centuries only. Yet, its misuse and mismanagement has caused severe problems of eutrophication of water and pollution of the environment. Thus, judicious management of soil phosphorus is essential. This volume is specifically devoted to availability and recycling of phosphorus, regulatory/policy issues of sustainable use of phosphorus, and management in agroecosystems in the context of maximizing the use efficiency and minimizing the environmental risks of water quality.

Mariele Neudecker - Sediment (Paperback): Mariele Neudecker Mariele Neudecker - Sediment (Paperback)
Mariele Neudecker; Edited by Greer Crawley; Una McCarthy, Ariane Koek, Kerstin Mey
R686 Discovery Miles 6 860 Ships in 12 - 17 working days

Mariele Neudecker is a German-born, Bristol-based artist working at the crossover of art and science. Her multimedia practice, which incorporates sculpture, video, painting and sound, explores the processes and effects of perception, the complexities and contradictions of landscapes and visuality, and the politics of representation and territorialisation. The influence of the nineteenth-century German romantic sublime is interwoven alongside inspiration from Neudecker's work with scientists, as a guest artist on the Arts at CERN programme, her trips to the Arctic and travel elsewhere. This major monograph, published following an exhibition of the same name at Limerick City Gallery of Art - Neudecker's first comprehensive solo exhibition in Ireland - presents more than 200 works from a 35-year-long career. In addition to a foreword by Una McCarthy, the gallery's Director and Curator, essays by distinguished academics and curators from across the fields of art and science address diverse areas of Neudecker's practice. A 'timeline' that Neudecker made specially for 'SEDIMENT' concludes the publication. Greer Crawley, an Honorary Research Fellow in the Department of Drama, Theatre and Dance at Royal Holloway, University of London, considers Neudecker's archive, studio and her working processes, while Ariane Koek, an international expert in the field of arts, science and technology, suggests that the contemporary sublime Neudecker is so often described as seeking is, for her, the very process of perception itself. Her comprehensive introduction to Neudecker's practice also discusses the tank works, for which the artist is best known, in which fibreglass landscapes are suspended in chemical solutions. James Peto, from the Wellcome Collection, London, focuses on issues of representation, post-colonialism and 'time', while Alice Sharp, Artistic Director of Invisible Dust, looks at Neudecker's work and collaborations concerning the deep sea. Klaus Dodds, Professor of Geopolitics at Royal Holloway, University of London, returns to questions of territorialisation in and around the Arctic, and Professor Kerstin Mey, Interim President of the University of Limerick, considers the genre of still life in Neudecker's photographic series 'Plastic Vanitas' (2015). Dominic Gray, Projects Director at Opera North, offers insight into Neudecker's work with sound and music, addressing issues of performance, translation and scale; while Pontus Kyander, an independent writer and curator based in Helsinki, returns to the motif of the forest, arguing that any reading of Neudecker's work might be taken beyond an interest in landscape and the sublime to incorporate contemporary ecological questions. Finally, Crawley's second offering returns to Neudecker's use of sound - its juxtaposition and superimposition, alongside the notion of the window as a device, considering how each creates 'temporal turbulences' and 'an entanglement of materiality, space, form and position,' foregrounding the artist's desire for viewers to see everything as eternally in flux. The publication, which is released to coincide with a new iteration of Neudecker's exhibition 'SEDIMENT' at Hestercombe, Somerset, in summer 2021, has been edited by Greer Crawley, designed by Herman Lelie and Stefania Bonelli, and printed by EBS Verona. It is published by Anomie Publishing, London. Mariele Neudecker (b. 1965, Dusseldorf, Germany) undertook a BA at Goldsmiths College, London (1987-90), and an MA in sculpture at Chelsea College of Art and Design, London (1990-1). She has shown widely in international solo and group exhibitions. Neudecker is Professor of Fine Art at Bath School of Art, where she runs the research cluster Making | Art | Science | Environment. She is on the Arts at CERN's guest programme, the European Commission's JRC SciArt advisory panel and the steering committee of Centre of Gravity, UK. Neudecker works with Pedro Cera, Lisbon; In Camera Gallery, Paris; and Thomas Rehbein Galerie, Cologne.

Soil Nitrogen Uses and Environmental Impacts (Paperback): Rattan Lal, B.A. Stewart Soil Nitrogen Uses and Environmental Impacts (Paperback)
Rattan Lal, B.A. Stewart
R1,495 Discovery Miles 14 950 Ships in 12 - 17 working days

Nitrogen (N) is potentially one of the most complex elements on the Earth. It is necessary for all biological activity, but creates negative impacts on water and air quality. There is a balancing act between deficiency and surplus and the forms of N available further complicate our understanding of the dynamics. Biological fixation provides some plants with N supply while others are totally dependent upon N being available in the soil profile for the roots to extract. Nevertheless, the demand for N will increase because the human population with its increasing growth requires more protein and thus more N. Understanding the global N cycle is imperative to meeting current and future nitrogen demands while decreasing environmental impacts. This book discusses availability, production, and recycling of N in air, water, plants, and soils. It features information on N impacts to soil and water quality, management of N in agroecosystems, and techniques to maximize the use efficiency while minimizing the risks of leakage of reactive N into the environment. This volume in the Advances in Soil Science series is specifically devoted to availability, production, and recycling of N with impact on climate change and water quality, and management of N in agroecosystems in the context of maximizing the use efficiency and minimizing the risks of leakage of reactive N (NO-3, N2O) into the environment.

P. Narayanasamy
R1,491 Discovery Miles 14 910 Ships in 12 - 17 working days

Crop disease management strategies revolve around the principles of exclusion, eradication and immunization. Cultural practices are aimed at preventing or reducing the accumulation of pathogen population (inoculum). Development of cultivars with genetic resistance by transgressing resistance gene(s) through traditional breeding procedures or biotechnological techniques is the most effective and acceptable strategy, as it is environment-friendly and does not need any additional cost to the grower. Assessment of different grades of resistance of cultivars or genotypes to soilborne microbial pathogens has been possible by quantifying pathogen populations or their DNA contents in the test plants by applying biological and molecular methods. This second volume of a two-volume set focuses on the soilborne microbial plant pathogens and the diseases caused by them. The book provides information on ecology and epidemiology of soilborne microbial plant pathogens and various strategies applicable for effective management of diseases. Chapters cover exclusion and prevention strategies; improvement of host plant resistance; biological management; application of chemicals; and integration of these disease management strategies. Features Discusses various aspects of soilborne microbial plant pathogens to develop effective methods of managing diseases. Presents information on epidemiology and ecology of soilborne microbial plant pathogens. Facilitates the application of management strategies alone or in combination with others for effective suppression of disease development. Features information on application of biotic and abiotic biological control agents (BCAs) to suppress pathogen development either by directly acting on the pathogen(s) or indirectly by enhancing host resistance to the pathogens. Employs biotic and abiotic biocontrol agents either to replace or reduce the use of chemicals is an achievable approach for managing the soilborne microbial pathogens.

Soil Degradation and Restoration in Africa (Paperback): Rattan Lal, B.A. Stewart Soil Degradation and Restoration in Africa (Paperback)
Rattan Lal, B.A. Stewart
R1,488 Discovery Miles 14 880 Ships in 12 - 17 working days

Soil degradation is a widespread problem in Africa resulting in decreased agricultural productivity while demand for food continues to increase. Degradation is caused by accelerated erosion, acidification, contamination, depletion of soil organic matter and plant nutrients, and salinization. The major cause of soil degradation in Africa is uncontrolled and excessive grazing in the savanna regions followed by deforestation and the use of inappropriate and extractive farming practices. Perpetual neglect of the health of soils in Africa can exacerbate the already serious problems of food and nutritional insecurity and environmental degradation. Food and nutritional security of the growing population of Africa can only be achieved if degraded soils are restored and soils of agroecosystems are managed prudently and sustainably. Ignoring soils and taking the fragile, finite and precious soil resources for granted is the principal cause of poverty, hunger, and environmental degradation. The downward spiral must be reversed through soil restoration measures based on translating science into action. This book describes the soils of Africa, processes of soil degradation, extent and severity of soil degradation, and the impacts of degradation processes on food and nutritional security. Features: Explores the extent and severity of soil degradation in Africa Analyzes the cause-effect relationship between anthropogenic activities and soil degradation Reviews processes of soil degradation in Africa including erosion, salinization, nutrient depletion, and decline of soil organic matter Addresses the effect of climate change on soil degradation in Africa. Explains how soil degradation causes food and nutritional insecurity Part of the Advances in Soil Sciences series, this volume is specifically devoted to the processes and factors that cause soil degradation and the challenges and potential for remediation and restoration of soil health in Africa.
