Nowadays, demands on modern civil engineering structures require not only safe technical solutions, but also additional approaches, involving ecological, sociological and economical aspects. This book reacts on these new requirements with a focus on earth structures for transport engineering, mainly for motorways and railways. Technical demands have to be adequately related to the risk with which the design and execution are connected. Soil used for the construction, together with subsoil, are natural materials with a high degree of inhomogeneity. Therefore, the risk when constructing with such materials is much higher than for structures utilizing man-made materials. The engineering approach is firstly focused on the geotechnical risk identification and subsequently on the reduction of this risk. Geotechnical risk is linked to the uncertainties for individual phases of the design and construction processes. Ground model, geotechnical design model, calculation model and structure execution are the main phases of the above-mentioned processes. Risk reduction involves the lowering of the range of uncertainties for individual phases, guaranteeing safe and optimal technical solutions. Eurocode 7 "Geotechnical design" creates a general frame of this risk identification and reduction approach. Earth structures are offering great opportunities for sustainability approach. Therefore, the possibilities how to decrease consumption of land (greenfields), energy and natural aggregates are at the centre of interest. In parallel to sustainability, the principles of availability and affordability for transport infrastructures are discussed. The main aim there is to eliminate the impact of interaction of the transport infrastructure with natural and man-made hazards, thus guaranteeing long-term functionality. This book will be of interest to specialists responsible for transport infrastructure planning, investors (project owners) of motorways and railways and environmental engineers. The main focus is on those responsible for geotechnical investigations, earth structures design and on contractors of such structures.

This book, first published in 1965, was the first by a British soil expert in which he wrote a study of his subject from a geographical, not an agricultural or biological, viewpoint. Chapters 1-8 deal with the factors and processes in soil formation. Chapters 9-17 describe the soil groups of the different regions of the world - for example, desert and tundra, the boreal zone, the Mediterranean, and intertropical areas.

This book describes the mechanisms of nutrient taken up by plants at the biochemical and molecular level. This is a new concept developed over the past 30 years, primarily due to use of modern technology developed in biotechnological research, instrumentation, modern computation facilities, bioinformatics, the large volumes of information generated by use of various 'omics' and of course the dedicated hard work of a large number of researchers. Recent research indicates that nutrient uptake, its transport and redistribution in plants are under genetic control. There are groups of genes for each nutrient that encode transporter proteins whose functions are to acquire the specific nutrient from the soil and transport it across the plasma membrane of the root hair cells for use in plant metabolism. Deficiency or sufficiency of a plant nutrient induces different groups of genes to produce m-RNA transcripts for translation of transporter proteins. A large number of metabolic enzymes are up or down regulated in response to deficiency of plant nutrients. Morphological and metabolic adaptations in order to better acquire nutrients and use them frugally when nutrients are scarce in the growth medium can be observed in plants. Heavy metals, which are toxic to plants, induce different sets of defence mechanisms. In 20 chapters, the book describes plants' uptake mechanisms for all the major, secondary and micronutrients, beneficial elements and heavy metals. References to research work quoted in the text are updated up to 2014 and included at the end of each chapter. Biotechnological approaches to improving nutrient use efficiency are discussed wherever such information is available. The structure and functions of transporter proteins involved in the uptake of nutrients are discussed. Additional information on some of the specific topics is provided in text boxes or as separate sections within the chapters. Lastly, the terminology used has been explained as far as possible in the text, mostly within parentheses.

Forage crops are an essential component of livestock's diet. Production and availability of sufficiently good quality forage under diverse ecological dynamics are fundamental to develop an efficient and productive livestock industry. Growers worldwide, especially in developing and underdeveloped countries, face significant challenges in producing sufficient winter fodder.

This book is written for researchers and practitioners in agronomy, biotechnology, bioecology and is a comprehensive guide for improving winter fodder production.

The search for new strategies of pest control with safer molecules is currently of great importance and interest. Microbe-mediated biological crop protection is an attractive and promising technology with no concern for a negative impact on the environment and biodiversity. Microbial hydrolytic enzymes such as proteases, chitinases, lipases, etc. are attractive for this purpose. They present toxic properties and act synergistically to control pest attacks. Also, some metabolites, that microorganisms produce for their survival or defense, can be explored and exploited for plant protection. The focus of this Volume is on the potential of microbial hydrolytic enzymes and their metabolites in agroecosystem functioning. Subsequent chapters review topics such as microbial hydrolytic enzymes as powerful management tools, chitinases in IPM of agro-horticultural crops, metabolites as pesticides and the importance of the metabolites of entomopathogenic fungi, metabolites and virulence factors. Other topicas include: microbial-based nanoparticles, recombinant DNA technologies to improve the efficacy of microbial insecticides, the effects of entomopathogens on insect predators and parasitoids, and the management of major vegetable insect pests. This Volume provides detailed accounts on the safe use of microbial products for sustainable management of insect pests. Its aim is to build solid foundations for the students, teachers, and researchers interested in eco-friendly management of important insect crop pests.

Merging together the fields of urban ecology, environmental justice, and urban environmental education, Urban Ecosystem Justice promotes building fair, accessible, and mutually beneficial relationships between citizens and the soils, water, atmospheres, and biodiversity in their cities. This book provides a framework for re-centering issues of justice and fairness in sustainability discourse while challenging the profound ecological alienation experienced by urban residents. While the urban sustainability movement has had many successes in the past few decades, there remain areas for it to grow. For one, the benefits of sustainability have disproportionately benefited wealthier city residents, with concerns over equity, justice, and social sustainability frequently taking a back seat to economic and environmental considerations. Additionally, many city dwellers remain estranged from and unfamiliar with ecological processes, with urban environments often thought of as existing outside of nature or as hopelessly degraded. Through a citizen-centered lens, the book offers a guide to reconciling these issues by demonstrating how questions of equity, access, and justice apply to the biophysical dimensions of the urban ecosystem: soil, water, air, waste, and biodiversity. Drawing heavily from the fields of urban ecology, environmental justice, and ecological design, this book lays out a science of cities for people: a pedagogical platform that can be used to promote ecological literacy in underrepresented urban communities through affordable and decentralized means. This book provides both a theoretical and practical field guide to students and researchers of urban sustainability, city planners, architects, policymakers, and activists wishing to develop reciprocal relationships with urban ecologies.

This book highlights recent advances in the discipline of biogeochemistry that have directly resulted from the development of critical zone (CZ) science. The earth's critical zone (CZ) is defined from the weathering front and lowest extent of freely circulating groundwater up through the regolith and to the top of the vegetative canopy. The structure and function of the CZ is shaped through tectonic, lithologic, hydrologic, climatic, and biological processes and is the result of processes occurring at multiple time scales from eons to seconds. The CZ is an open system in which energy and matter are both transported and transformed. Critical zone science provides a novel and unifying framework to consider those coupled interactions that control biogeochemical cycles and fluxes of energy and matter that are critical to sustaining a habitable planet. Biogeochemical processes are at the heart of energy and matter fluxes through ecosystems and watersheds. They control the quantity and quality of carbon and nutrients available for living organisms, control the retention and export of nutrients affecting water quality and soil fertility, and influence the ability for ecosystems to sequester carbon. As the term implies, biogeochemical cycles, and the rates at which they occur, result from the interaction of biological, chemical, and physical processes. However, finding a unifying framework by which to study these interactions is challenging, and the different components of bio-geo-chemistry are often studied in isolation. The authors provide both reviews and original research contributions with the requirement that the chapters incorporate a CZ framework to test biogeochemical theory and/or develop new and robust predictive models regarding elemental cycles. The book demonstrates how the CZ framework provides novel insights into biogeochemistry.

Originally published in 1988 Deforestation examines deforestation as a major environmental and development problem. It examines the issues of forests being cut in tropical and mountain areas, and how acid rain, pollution and disease wreak havoc in temperate zones. Some of the worst effects of deforestation have been changes in the world's climate system, erosion and flooding, desertification, wood short-ages and the disappearance of some floral and fauna species. This book challenges the belief that deforestation is due to entirely rapid population growth and agricultural expansion and emphasises the effects of commercial exploitation and poor planning and management. In concludes with a programme for reforestation using agro-forestry, appropriate cottage industries, improved international programmes, local land reforms and community participation.

This book provides a review of problems during design and construction on problematic soils. Design methods, site investigation, construction and analysis of the various improvement methods available are explained and discussed. Various regions may have different soils with geotechnical problems that differ from those faced in other regions. For example, in Southeast Asia, the common geotechnical problems are those associated with construction on soft clays and organic soils, while in the arid region of the Middle East, problems are generally associated with the desert soils. In the US, the problems are associated with organic soils, expansive and collapsing soils, and shale. Laterite and lateritic soils are especially problematic in Mexico. Similarly, in Europe, for example, the geotechnical problems are associated with loess (France), and organic soil (Germany). A detailed description of various methods of ground improvement has been provided in 11 chapters. Each chapter deals not only with a description of the method but also focuses on region-specific ground problems and suitable ground improvement techniques. Case studies have also been included. One general chapter is dedicated to site investigation, instrumentation, assessment and control. This book will be of value to students and professionals in the fields of civil and geotechnical engineering, as well as to soil scientists and engineering geologists.

The main effects of Seaweed extracts (Ascophyllum, Fucus, Sargassum, Saccorhiza, Laminaria, Gelidium and others), when used as agricultural fertilizers, are better seed germination and higher quality fruit production, with longer shelf life; better use of soil nutrients; more productive crops and plants with greater resistance to unfavorable environmental conditions. Algae also have a long history of use as animal feed. They have a highly variable composition depending on the species, collection season and habitat, and on external conditions such as water temperature, light intensity and nutrient concentration in water. In relation to ruminal fermentation, a high variability of the digestibility values was found among seaweed species and cannot be attributed only to the composition of different nutrients of the algae. The role of marine algae for reduction of methane production is discussed with particular emphasis on novel algae-based feed strategies that target minimal methane emissions without affecting the functionality of the microbiota and overall animal productivity.

This important volume provides a plethora of information on aerial vehicles and their possible roles in revolutionizing agricultural procedures through spectral analysis of terrains, soils, crops, water resources, diseases, floods, drought, and farm activities. There are several semi-autonomous and autonomous (robotic) aerial vehicles that are examined for their efficiency in offering detailed spectral data about agrarian regions and individual farms. Among them, small drone aircrafts such as fixed-winged and copter models have already caught the imagination of farmers. They are spreading fast in every nook and corner of the farm world. However, there are many more aerial robots that are utilized in greater detail during farming. In this volume, the focus is on aerial vehicles such as parafoils, blimps, aerostats, and kites, and how they are being evaluated for use in experimental farms and fields. A few aerial vehicles, such as robotic parafoils, have been adopted to procure aerial spectral data and visual imagery to aid agronomic procedures. These and other aerial robots are expected to change and improve the use of the sky in agricultural endeavors and the way we conduct agronomic procedures in the very near future. This volume is a timely resource for agricultural researchers, professors and students, and the general public who are interested in aerial vehicles.
