This book examines the implications of the net zero transition for food and farming in the UK and how these can be managed to avoid catastrophic climate change in the crucial decades ahead. For the UK to meet its international obligations for reducing greenhouse gas emissions, nothing short of a revolution is required in our use of land, our farming practices and our diet. Taking a historical approach, the book examines the evolution of agriculture and the food system in the UK over the last century and discusses the implications of tackling climate change for food, farming and land use, setting the UK situation in an international context. The chapters analyse the key challenges for this transition, including dietary change and food waste, afforestation and energy crops, and low-emission farming practices. This historical perspective helps develop an understanding of how our food, farming and land use system has evolved to be the way that it is, and draws lessons for how the agri-food system could evolve further to support the transition to net zero and avoid catastrophic climate change. Written in a clear and accessible style, this book will be essential reading to students and scholars of food, agriculture and the environment, as well as policymakers and professionals involved climate change policy and the agriculture and food industry.

Environmental science and engineering is a truly interdisciplinary field. From its origins in public health practice, concern for the well-being of our environment has embraced areas as diverse as chemistry, the earth sciences, biology, engineering and law. The specialist language of any discipline can be a barrier to co-operation and understanding in solving environmental problems. The Dictionary of Environmental Science and Engineering explains many important specialist environmental terms in a clear and concise way. It also provides an extensive guide to the many acronyms encountered in environmental science. The Dictionary of Environmental Science and Engineering will be a valuable reference tool for anyone working, whether directly or indirectly, with the environment. The dictionary describes many of the acts, organisations and requirements related to the legislation of the environment, giving particular emphasis to those of the United States of America. Thus, it will be particularly useful to those seeking a greater understanding of the US perspective on the environmental question.

In the last fifty years our butterfly populations have declined by more than eighty per cent and butterflies are now facing the very real prospect of extinction. It is hard to remember the time when fields and meadows were full of these beautiful, delicate creatures - today we rarely catch a glimpse of the Wild Cherry Sphinx moths, Duke of Burgundy or the even once common Small Tortoiseshell butterflies. The High Brown Fritillary butterfly and the Stout Dart Moth have virtually disappeared. The eminent entomologist and award-winning author Josef H. Reichholf began studying butterflies in the late 1950s. He brings a lifetime of scientific experience and expertise to bear on one of the great environmental catastrophes of our time. He takes us on a journey into the wonderful world of butterflies - from the small nymphs that emerge from lakes in air bubbles to the trusting purple emperors drunk on toad poison - and immerses us in a world that we are in danger of losing forever. Step by step he explains the science behind this impending ecological disaster, and shows how it is linked to pesticides, over-fertilization and the intensive farming practices of the agribusiness. His book is a passionate plea for biodiversity and the protection of butterflies.

Tackling environmental issues such as global warming, ozone depletion, acid rain, water pollution, and soil contamination requires an understanding of the underlying science and chemistry of these processes in real-world systems and situations. Chemistry for Environmental and Earth Sciences provides a student-friendly introduction to the basic chemistry used for the mitigation, remediation, and elimination of pollutants. Written and organized in a style that is accessible to science as well as non-science majors, this textbook divides its content into four intuitive chapters: Fire, Earth, Water, and Air. The first chapter explains classical concepts in chemistry that occur in nature such as atomic and molecular structures, chemical bonding and reactions, states of matter, phase transitions, and radioactivity. Subsequent chapters focus on the chemistry relating to the geosphere, hydrosphere, and atmosphere-including the chemical aspects of soil, water, and air pollution, respectively. Chemistry for Environmental and Earth Sciences uses worked examples and case studies drawn from current applications along with clear diagrams and concise explanations to illustrate the relevance of chemistry to geosciences. In-text and end-of-chapter questions with complete solutions also help students gain confidence in applying concepts from this book towards solving current, real-world problems.

This new book offers an engineer's perspective on the history of water technology and it's impact on the development of civilisation.

Water professionals, engineers, scientists, and students will find this book fascinating and invaluable to their understanding of the fundamental role of water engineering in the development of civilization. The book abounds with descriptions of hydraulic techniques in the civilizations of the classical era and the Middle Ages, including illustrations ands translated descriptions of ancient observers and authors. The work is unique in offering an engineer perspective not only on the history of water technology, but also demonstration of the genesis of ideas and the transmissions of ideas and technology from one age and civilization to the next. The book is specially noteworthy for its efforts to situate hydraulic developments in their historical and intellectual context.

Conservation tillage systems have been adopted by farmers in many countries to solve the problem of land degradation and declining water productivity. Direct application of such tillage systems has not been possible among resource-poor, smallholder farmers in semi-arid areas of Ethiopia. Problems such as the lack of rainfall, the costs of herbicides and implements, and the special cultivation needs of the crop tef, which can not be planted in rows, have developed locally-adapted conservation tillage systems. This book considers traditional tillage systems and the results of tests carried out on appropriate conservation tillage implements and systems for smallholder farmers in semi-arid regions of Ethiopia. The traditional tillage implement, the Maresha Plough, and the related tillage systems were identified as being the main cause of repeated and cross-ploughing, leading to land degradation and reduced water productivity. Modified implements were found to be suitable for conservation tillage systems while being simple, light and affordable. Two types of tillage systems developed for maize and tef were found to reduce surface runoff, increase availability of water to crops and increase yields.

In recent years, increasing attention and resources have been brought to bear on the relationship between the environment and congenital diseases. These diseases were previously thought to be mostly due to genetic causes. Even though the importance of genes as factors in causation is accepted, environmental factors seem to be implicated just as strongly. This book explores some further concepts that have arisen from more recent perceptions of environmental effects and their possible interactions with living systems. Amongst the topics discussed are: effects of prenatal exposure to toxic chemicals; intra-uterine exposure to drugs; effects of endocrine disrupters; environmental risk and sex ratio in newborns; surveillance of environmental impact; research and policy.

Environmental science is an interdisciplinary academic field that integrates physical-, biological-, and information sciences to study and solve environmental problems. ESSE - The International Conference on Environmental Science and Sustainable Energy provides a platform for experts, professionals, and researchers to share updated information and stimulate the communication with each other. In 2017 it was held in Suzhou, China June 23-25, 2017.

When wastewater infiltrates into the soil, groundwater may be contaminated. If the distance from source of pollution to point of groundwater abstraction is small, there is a real chance of abstracting pathogenic microorganisms. In this book, the transport of Escherichia coli in aquifers under saturated conditions is studied. Starting point is the well known colloid filtration theory. Straining or physical sieving, geochemical heterogeneity, variable deposition rate coefficients, and preferential flow mechanisms are then included in the theory. The case of Sana'a, the capital of Yemen, served to evaluate the importance of bacteria transport processes in a field situation. This book is useful for hydrogeologists concerned with microbiological contamination of aquifers.

Utilizing a multispecies lens and anticolonial framework, contributors to this special issue seek to reconceptualize justice to include beings beyond the human realm. The authors imagine how existing political institutions—which determine the meaning and distributions of value and power—might be formed and transformed in ways that respond to and afford justice in the lives, relations, and socialities of other-than-human beings. This institutional shift, the authors argue, would disrupt uneven fields of identity-based power, inequality, marginalization, and privilege. It would also foster practices of living together in ways that are hospitable to a broader range of subjects, both human and nonhuman, at a time of socio-ecological unraveling, threat, and instability. Essays cover a variety of topics, including the subterranean estrangement of stygofauna, slaughterhouses and factory farms, anticolonial conceptions of justice, critical plant studies, ecofeminism, and Indigenous cosmopolitics. The authors of this collection engage with methods and concepts derived from fields including cultural theory, anthropology, political theory, philosophy, art, history of science, queer/feminist theory, law, and conservation science.

Environmental Chemistry is a relatively young science. Interest in this subject, however, is growing very rapidly and, although no agreement has been reached as yet about the exact content and limits of this interdisciplinary discipline, there appears to be increasing interest in seeing environmental topics which are based on chemistry embodied in this subject. One of the first objectives of Environ mental Chemistry must be the study of the environment and of natural chemical processes which occur in the environment. A major purpose of this series on Environmental Chemistry, therefore, is to present a reasonably uniform view of various aspects of the chemistry of the environment and chemical reactions occurring in the environment. The industrial activities of man have given a new dimension to Environ mental Chemistry. We have now synthesized and described over five million chemical compounds and chemical industry produces about hundred and fifty million tons of synthetic chemicals annually. We ship billions of tons of oil per year and through mining operations and other geophysical modifications, large quantities of inorganic and organic materials are released from their natural deposits. Cities and metropolitan areas of up to 15 million inhabitants produce large quantities of waste in relatively small and confined areas. Much of the chemical products and waste products of modern society are released into the environment either during production, storage, transport, use or ultimate disposal. These released materials participate in natural cycles and reactions and frequently lead to interference and disturbance of natural systems.

Fingerponds are earthen ponds dug at the edge of natural wetlands and stocked naturally with wild fish during flooding. They preserve the wetland environment in which they are situated while maintaining a productive culture system. In this study, the importance of organic manure applications in enhancing nutrient levels, phytoplankton and periphyton productivities and ultimately fish production was examined in experimental Fingerponds set up with the participation of local communities in Uganda. Results show that organic manures enhance algal development and fish production in Fingerponds, but close monitoring and control are needed. Fish yields in Fingerponds can be enhanced to 1500 - 2800 kg/ha over a functional period of 200 to 300 days using animal manure (e.g. chicken), fermented green manure and artificial substrates for periphyton development. Good management practices are required to regulate pond inputs and conditions. High clay turbidity, nitrogen limitation and high recruitment of fish can limit fish production. Overall, Fingerponds were shown to be an effective addition to protein production for poor riparian communities in East Africa and are recommended for adoption.

Pathogen removal mechanisms in macrophyte and algal-based waste stabilization ponds were studied in Ghana and Colombia. The macrophytes used were water lettuce (Pistia stratiotes) and duckweeds (Lemna paucicostata and Spirodela polyrhiza). The selection of the species was based on economic importance and availability. Lemna was used during the initial investigations. However, Lemna could not withstand the ammonia levels in the wastewater used. Spirodela polyrhiza a rarer species in Ghana was therefore used in subsequent studies. The main mechanisms considered in this study were pH, protozoa predation and surface attachment. The microorganisms used were faecal bacteria namely; Escherichia coli, other coliforms, Salmonella sp., other enterobacteria, E. coli, ATCC13706 and enterococci. Studies were conducted using batch scale, continuous flow bench and pilot scale ponds. Results indicated in order of importance that long retention periods, attachment, sedimentation, predation and low pH are mechanisms in macrophyte ponds enhancing faecal bacteria removal, while in the algal ponds long retention periods, sunlight penetration, high pH, attachment and sedimentation are the mechanisms of importance in faecal bacteria removal. Presence of protozoa was also found to be important but true grazing studies could not be quantified. Dissolved oxygen did not play a major role in faecal bacteria removal.

This book presents the results of research conducted between 2000 and 2004 on Lake Victoria (East Africa). The research examined the spatial spread of shoreline wetlands and found their distribution to be strongly influenced by the action of wind and waves. Evidence also pointed to a strong influence of wind-induced waves and currents on within-lake transport of surficial sediments. Paleolimnological reconstructions from bottom sediments confirmed earlier studies demonstrating the occurrence of eutrophication, and suggested that climate change was a co-driver of lake ecosystem change. It is argued that eutrophication could have led to destruction of a number of littoral plants species and has induced changes in fish populations. The study concludes by recommending the introduction of catchment management measures to reduce the export of nutrients to the lake.
