Lament for an Ocean: The Collapse of the Atlantic Cod Fishery
by Michael HarrisThe northern cod have been almost wiped out. Once the most plentiful fish on the Grand Banks off the coast of Newfoundland, the cod is now on the brink of extinction, and tens of thousands of people in Atlantic Canada have been left without work by a 1992 moratorium on fishing the stock. Today, the Pacific salmon stocks are in similar trouble – victims of the same blind, stupid greed. Angry, accusatory fingers have been pointed at various possible culprits for the collapse of the cod – at the Spanish and Portuguese, who for hundreds of years sent ever-bigger fleets to the Grand Banks; at the factory-freezer trawlers, which “vacuumed” the ocean floor for the prized fish; at those inshore fishermen who circumvented the rules governing the fishery; at the federal Department of Fisheries and Oceans, which is responsible for managing the fishery; at the harp seal, the cod’s competitor for food, whose numbers have exploded in recent years; even at Nature, for lowering the temperature of the ocean. InLament for an Ocean,the award-winning true-crime writer Michael Harris investigates the real causes of the most wanton destruction of a natural resource in North American history since the buffalo were wiped off the face of the prairies. The story he carefully unfolds is the sorry tale of how, despite the repeated and urgent warnings of ocean scientists, the northern cod was ruthlessly exploited.
The Laminar Boundary Layer Equations (Dover Books on Physics)
by N. CurleA thorough introduction to the study of boundary layer problems in physics and fluid mechanics, this treatment assumes some knowledge of classical inviscid fluid dynamics. The ordered and logical presentation is accessible to undergraduates, and professionals will benefit from the careful expositions of the limitations and accuracy of various methods.An extensive introduction explains the boundary-layer concept and demonstrates its simplification of equations of viscous flow. Successive chapters address various aspects of solution in incompressible flow, starting with analytic solutions of the velocity field and advancing to discussions of high-accuracy numerical solutions, practical methods of calculation, and an analysis of factors that might govern the choice of a method. Several chapters on the compressible laminar boundary layer include examinations of pressure gradient and heat transfer, followed by a brief exploration of some aspects of the problem of the interaction between shock waves and laminar boundary layers. Complete references and a helpful Index conclude the text.

Land Allocation for Biomass Crops: Challenges and Opportunities with Changing Land Use
by Andrea Monti Ruopu LiThis edited volume establishes a forum for international experts to explore cutting-edge questions associated with the land use and biomass production. Topics include ‘do we have enough land, either primary or marginal, to accommodate future production of biomass?’, ‘how are farming decisions made in response to biomass incentives?’, ‘is the current bio-mass production socially, economically and environmentally sustainable?’, and ‘what are the main constraints currently limiting biofuel deployment?’ The expansion of biomass production is often at the cost of reduced land availability for food production and losses of areas with ecological functions such as forests and wetlands. This process often involves complex interplay of physical dynamics and human systems that are driven by numerous geographic and socio-economic factors at different scales. Thus, the state-of-the-art research on the land use issues surrounding the biomass production and its environmental impacts is important for informed land management decision making. This book will be of great use to researchers in land use management and biomass-based renewable energy, as well as practitioners.
Land and Disaster Management Strategies in Asia
by Huong HaThis book focuses on land and disaster governance in Asian countries. The Asian region has become increasingly vulnerable to natural disasters, including floods, cyclones, storms, earthquakes, drought, typhoons and tsunamis. Further, as a result of unsustainable changes being made in patterns of land use, catchment and coastal zones, increasing population density, migration patterns, and the spread of consumer culture across countries, the impact of natural disasters has increased manifold. The book addresses two major concerns in this field. Firstly, it discusses topics intended to raise awareness among all stakeholders of the critical aspects of disaster management in the context of Asia. Secondly, it calls upon policymakers, researchers, academics, practitioners, private enterprises and civil society organizations, as well as all those who have been, are and will be affected by natural disasters to search for innovative and novel approaches to reducing risk and managing disasters.

Land-Atmospheric Research Applications in South and Southeast Asia (Springer Remote Sensing/photogrammetry Ser.)
by Krishna Prasad Vadrevu Toshimasa Ohara Chris JusticeThis edited volume sheds new light on the impact of rapid Land Use/Cover Changes (LU/CC) on greenhouse gases (GHG’s) and aerosol emissions in South and Southeast Asia. Several countries in South/Southeast Asia have the highest population growth rates in the world, which is the main cause for LU/CC. Conversion of dense forests to agricultural areas and then to residential and urban areas is most commonly observed in South/Southeast Asian countries with a significant release of GHG’s and aerosols. The book showcases several case studies on the use of remote sensing and geospatial technologies to quantify biomass burning and air pollution impacts, aerosol pollution, LU/CC, and impacts on ecosystem services. The book also includes articles on regional initiatives in research, capacity building, and training. The authors of this book are international experts in the field, and their contributions highlight significant drivers and impacts of air pollution in South/Southeast Asia. Readers will discover the latest tools and techniques, in particular, the use of satellite remote sensing and geospatial technologies for quantifying GHG’s, aerosols and pollution episodes in this region.
A Land Between Two Niles: Quaternary geology and biology of the Central Sudan
by Martin A.J. Williams; D.A.AdamsonThree themes run through this book, the first is the history of the Nile; the second is the degree to which the present Sudanese landscape reflects the operation of former geological processes; the third is the interaction between man and environment, not always to the benefit of either. A land between two Niles is an interdisciplinary account of the origins and characteristics of the alluvial plains of the lower Blue and White Nile. The contributors have focussed their attention upon this region for several reasons. Although the Gezira plain itself only occupies about one percent of the total area of the Sudan, the high quality long-staple cotton grown there provides nearly two-thirds of the country’s total export revenue.
Land Carbon Cycle Modeling: Matrix Approach, Data Assimilation, & Ecological Forecasting
by Yiqi Luo Benjamin SmithCarbon moves through the atmosphere, through the oceans, onto land, and into ecosystems. This cycling has a large effect on climate – changing geographic patterns of rainfall and the frequency of extreme weather – and is altered as the use of fossil fuels adds carbon to the cycle. The dynamics of this global carbon cycling are largely predicted over broad spatial scales and long periods of time by Earth system models. This book addresses the crucial question of how to assess, evaluate, and estimate the potential impact of the additional carbon to the land carbon cycle. The contributors describe a set of new approaches to land carbon cycle modeling for better exploring ecological questions regarding changes in carbon cycling; employing data assimilation techniques for model improvement; and doing real- or near-time ecological forecasting for decision support. This book strives to balance theoretical considerations, technical details, and applications of ecosystem modeling for research, assessment, and crucial decision making. Key Features Helps readers understand, implement, and criticize land carbon cycle models Offers a new theoretical framework to understand transient dynamics of land carbon cycle Describes a suite of modeling skills – matrix approach to represent land carbon, nitrogen, and phosphorus cycles; data assimilation and machine learning to improve parameterization; and workflow systems to facilitate ecological forecasting Introduces a new set of techniques, such as semi-analytic spin-up (SASU), unified diagnostic system with a 1-3-5 scheme, traceability analysis, and benchmark analysis, for model evaluation and improvement Related Titles Isabel Ferrera, ed.

Land Cover and Land Use Change on Islands: Social & Ecological Threats to Sustainability (Social and Ecological Interactions in the Galapagos Islands)
by Stephen J. Walsh Philip H. Page Diego Riveros-Iregui Javier Arce-NazarioGlobalization is not a new phenomenon, but it is posing new challenges to humans and natural ecosystems in the 21st century. From climate change to increasingly mobile human populations to the global economy, the relationship between humans and their environment is being modified in ways that will have long-term impacts on ecological health, biodiversity, ecosystem goods and services, population vulnerability, and sustainability. These changes and challenges are perhaps nowhere more evident than in island ecosystems. Buffeted by rising ocean temperatures, extreme weather events, sea-level rise, climate change, tourism, population migration, invasive species, and resource limitations, islands represent both the greatest vulnerability to globalization and also the greatest scientific opportunity to study the significance of global changes on ecosystem processes, human-environment interactions, conservation, environmental policy, and island sustainability.In this book, we study islands through the lens of Land Cover/Land Use Change (LCLUC) and the multi-scale and multi-thematic drivers of change. In addition to assessing the key processes that shape and re-shape island ecosystems and their land cover/land use changes, the book highlights measurement and assessment methods to characterize patterns and trajectories of change and models to examine the social-ecological drivers of change on islands. For instance, chapters report on the results of a meta-analysis to examine trends in published literature on islands, a satellite image time-series to track changes in urbanization, social surveys to support household analyses, field sampling to represent the state of resources and their limitations on islands, and dynamic systems models to link socio-economic data to LCLUC patterns. The authors report on a diversity of islands, conditions, and circumstances that affect LCLUC patterns and processes, often informed through perspectives rooted, for instance, in conservation, demography, ecology, economics, geography, policy, and sociology.
Land Cover Classification of Remotely Sensed Images: A Textural Approach
by S. JenickaThe book introduces two domains namely Remote Sensing and Digital Image Processing. It discusses remote sensing, texture, classifiers, and procedures for performing the texture-based segmentation and land cover classification. The first chapter discusses the important terminologies in remote sensing, basics of land cover classification, types of remotely sensed images and their characteristics. The second chapter introduces the texture and a detailed literature survey citing papers related to texture analysis and image processing. The third chapter describes basic texture models for gray level images and multivariate texture models for color or remotely sensed images with relevant Matlab source codes. The fourth chapter focuses on texture-based classification and texture-based segmentation. The Matlab source codes for performing supervised texture based segmentation using basic texture models and minimum distance classifier are listed. The fifth chapter describes supervised and unsupervised classifiers. The experimental results obtained using a basic texture model (Uniform Local Binary Pattern) with the classifiers described earlier are discussed through the relevant Matlab source codes. The sixth chapter describes land cover classification procedure using multivariate (statistical and spectral) texture models and minimum distance classifier with Matlab source codes. A few performance metrics are also explained. The seventh chapter explains how texture based segmentation and land cover classification are performed using the hidden Markov model with relevant Matlab source codes. The eighth chapter gives an overview of spatial data analysis and other existing land cover classification methods. The ninth chapter addresses the research issues and challenges associated with land cover classification using textural approaches. This book is useful for undergraduates in Computer Science and Civil Engineering and postgraduates who plan to do research or project work in digital image processing. The book can serve as a guide to those who narrow down their research to processing remotely sensed images. It addresses a wide range of texture models and classifiers. The book not only guides but aids the reader in implementing the concepts through the Matlab source codes listed. In short, the book will be a valuable resource for growing academicians to gain expertise in their area of specialization and students who aim at gaining in-depth knowledge through practical implementations. The exercises given under texture based segmentation (excluding land cover classification exercises) can serve as lab exercises for the undergraduate students who learn texture based image processing.
Land Degradation in India: Linkages with Deforestation, Climate and Agriculture (SpringerBriefs in Environmental Science)
by Ratan PriyaThis book discusses land degradation in India using statistical tools such as Principal Component Analysis (PCA) and Regression Analysis (RA), and uses statistical analyses and graphical representations of the causal relationship between land degradation and land productivity to determine linkages with deforestation, climate change and agricultural productivity. While most studies of land degradation in India focus on economic outcomes and physical processes at macro and micro levels, this study addresses land degradation at the meso-level to fill in this gap and provide up-to-date information on often overlooked factors associated with land degradation issues using the latest available data. Districts in the study were selected by land degradation intensity, forming an index of the severity of land degradation in the area, with a focus on gullied lands, soil salinity/alkalinity and open and dense scrubs as indicators. Though the study areas are in India, researchers, policy makers and students around the world will be able to learn from these inputs regarding land degradation to address various challenges associated with sustainable land management and agricultural productivity.
Land Degradation in the Dinder and Rahad Basins: Interactions Between Hydrology, Morphology and Ecohydrology in the Dinder National Park, Sudan (IHE Delft PhD Thesis Series)
by Khalid Elnoor HassaballahThe spatial and temporal variability of the hydro-climate as well as land use and land cover (LULC) changes are among the most challenging problems facing water resources management. Understanding the interaction between climate variability, land use and land cover changes and their links to hydrology, river morphology and ecohydrology in the Dinder and Rahad basins in Sudan is confronted by the lack of climatic, hydrological and ecological data. This book investigated the impacts of land degradation on the Dinder and Rahad hydrology and morphology, and interlinkage to the ecohydrological system of the Dinder National Park (DNP) in Sudan. It used an ensemble of techniques to improve our understanding of the hydrological processes and LULC changes in these basins. This included long-term trend analysis of hydroclimatic variables, LULC changes analysis, field measurements, rainfall-runoff modelling, hydrodynamic and morphological modelling of the Dinder river and its floodplain, with special focus on the Mayas wetlands. Moreover, this research is the first study to investigate the eco-hydrology of the DNP. It is expected that the results of the study will be beneficial to all stakeholders concerned and support decision-making processes for better management of water resources and ecosystem conservation in the area and possibly beyond.
Land Degradation Neutrality: Achieving SDG 15 by Forest Management
by Pankaj Panwar Gopal Shukla Jahangeer A. Bhat Sumit ChakravartyThis edited book covers all aspects of forest deforestation and degradation in detail and their link to land degradation. Poor natural resource management is often a contributory factor in the depletion of resources particularly like degradation of land which hinders the goals to achieve land degradation neutrality (LDN). Sustainable Development Goal (SDG) target 15.3 states: “By 2030, combat desertification, restore degraded land and soil, including land affected by desertification, drought, and floods, and strive to achieve a land degradation-neutral world.” To achieve the set goals a comprehensive multidirectional approach is required involving policymakers, field functionaries, researchers, and above all educators. The book compiles the field experiences and wisdom of some of the best researchers and authors working in the field of land degradations for quite a long time. The objective of the book is to disseminate the status of land degradation, the importance of achieving land degradation and share success stories of reclaiming Land degradation, and suggests means and ways of achieving land degradation neutrality. This book act as a repository of knowledge on Land degradation neutrality for students, researchers and practitioners, and policy planners.

Land Subsidence Induced by the Engineering-Environmental Effect
by Zhen-Dong CuiThis book brings forward the concept of the geology-environmental capacity of ground buildings. It quantifies the geology-environmental capacity of ground buildings by analyzing the main factors of land subsidence and setting up the evaluation system. The geological environmental capacity of ground buildings is mainly controlled by the land subsidence and the output is the floor area ratio. According to the different geology structures and the different requirements of subsidence control in the soft soil areas in Shanghai, the evaluation system of the floor area ratio is built up by the adaptive neuro-fuzzy inference system (ANFIS) and the floor area ratios of four typical regions (Lujiazui, Xujiahui, Zhongyuan and Changqiao) are obtained by the ANFIS to offer references for urban planning. By taking the typical soft soil areas in Shanghai as case studies, this book will provide valuable insights to professors and graduate students in the field of Geotechnical Engineering, Civil Engineering, Engineering Geology and Environmental Geology.
