R665 R519 Discovery Miles 5 190 Save R146 (22%) Ships in 5 - 10 working days

*A Times, Financial Times, Observer and Nature Book of the Year* We still have time to change the world. From Greta Thunberg, the world's leading climate activist, comes the essential handbook for making it happen. You might think it's an impossible task: secure a safe future for life on Earth, at a scale and speed never seen, against all the odds. There is hope - but only if we listen to the science before it's too late. In The Climate Book, Greta Thunberg has gathered the wisdom of over one hundred experts - geophysicists, oceanographers and meteorologists; engineers, economists and mathematicians; historians, philosophers and indigenous leaders - to equip us all with the knowledge we need to combat climate disaster. Alongside them, she shares her own stories of demonstrating and uncovering greenwashing around the world, revealing how much we have been kept in the dark. This is one of our biggest challenges, she shows, but also our greatest source of hope. Once we are given the full picture, how can we not act? And if a schoolchild's strike could ignite a global protest, what could we do collectively if we tried? We are alive at the most decisive time in the history of humanity. Together, we can do the seemingly impossible. But it has to be us, and it has to be now.

Wild Waters - A wildlife and water lover's companion to the aquatic world (Paperback): Susanne Masters Wild Waters - A wildlife and water lover's companion to the aquatic world (Paperback)
Susanne Masters; Illustrated by Alice Goodridge
R485 Discovery Miles 4 850 Ships in 12 - 17 working days

About seventy-one per cent of the Earth's surface is water, and even on dry land we remain closely connected to aquatic life. It provides us with oxygen, food, medicine and materials. Wild waterlife infiltrates our lives in many surprising ways. Every other breath we take is filled with oxygen provided by ocean-dwelling microscopic plants. A type of seaweed provides a means to directly test whether people are infected with viruses, including Covid-19. Robotics design takes inspiration from a pike's ability to accelerate with greater g-force than a Porsche. Wild Waters by Susanne Masters is a celebration of the breadth of wildlife that can be found in and around our varied waterways, from oceans and rivers to rock pools and ponds. Armchair explorers can read a fascinating account of how aquatic plants and animals enrich human life. Swimmers, paddleboarders, dog walkers, families and anyone with a passion for the great outdoors can learn about local wildlife, including when and where to look for different species without causing any harm. With stunning illustrations by Alice Goodridge, Wild Waters provides a tantalising insight into the world beneath the surface.

'Dust is a book with an extraordinary global story to tell, but - and - also with an ethical argument to advance. Robert Macfarlane Combining history and science, a sweeping look at the smallest substance and the biggest challenges facing people and the planet __________ Dust may seem inconsequential, so tiny and mundane as to slip below the threshold of thought. Yet within the next one hundred years, life on Earth will be profoundly changed by heat and drought - and that means dust. In this ground-breaking book, Jay Owens argues that dust is a legacy of twentieth-century progress and a toxic threat to life in the twenty-first. Dust: The Modern World in a Trillion Particles tells the gripping story of how the relentless drive for profit and power has turned the world to powder. Combining history and science, travel and nature writing, Owens shows how the modern world was made through environmental devastation - and then brushed the consequences under the carpet. From particle air pollution and nuclear fallout to desertification, dried-up seas and melting glaciers, we've profoundly altered the planet we live on. The cost to human health - and to the natural world - proves immense. From the California desert and the Dust Bowl in Oklahoma to the desiccated remains of the Aral Sea and the edge of the Greenland ice sheet, we are shown that some of the planet's most remote and forgotten places are central to the modern world. With clarity and insight, Dust: The Modern World in a Trillion Particles helps us understand our legacy and discovers the big ideas found within the smallest particles. __________

Junaid Ahmad Malik, Megh R. Goyal
R14,854 Discovery Miles 148 540 Ships in 12 - 17 working days

This 4-volume set focuses on the use of microbial bioremediation and phytoremediation to clean up pollutants in soil, such as pesticides, petroleum hydrocarbons, metals, and chlorinated solvents, which reduce the soil's fertility and renders it unfit for plant growth. The volumes cover the many diverse eco-friendly microbial bioremediation and phytoremediation techniques for sustainable soil management. Bioremediation and Phytoremediation Technologies in Sustainable Soil Management: Volume 1: Fundamental Aspects and Contaminated Sites begins with an overview of phytoremediation and phytotechnologies and the role of environmental factors. It goes on to introduce soil assessment techniques and offers methods of remediation designed to combat soil and agricultural degradation. Attention is given to specific types of sites and soil pollution, such as soils contaminated by heavy metals; microbial and phytoremediation-based removal of polycyclic aromatic hydrocarbons (PAHs) from coal, crude oil, and gasoline; microbial bioremediation and amelioration of pesticide-contaminated soils; phytoremediation techniques for biomedical waste contaminated sites; as well as biomediation processes for human waste sites. Biopesticides are also explained in the book as an alternative to conventional pesticides as well as the possibilities for the improvement of modern bio-pesticides. Volume 2: Microbial Approaches and Recent Trends focuses on new and emerging techniques and approaches to address soil pollution. These include the use of rhizobacteria, archae, cyanobacteria, and microalgae as biofertilizers and for soil bioremediation efforts. New technologies for assessment of soil bioremediation are explored also. The chapters provides in-depth coverage of the mechanisms, advantages, and disadvantages of the technologies used and highlights the use of different microbial enzymes that are used in the process of bioremediation and phytoremediation to clean up different pollutants without causing damage to the natural environment. Volume 3: Inventive Techniques, Research Methods, and Case Studies is organized in three themes: plants in green remediation, tools and techniques in bioremediation and phytoremediation, and special sites and their remediation techniques. Innovative new techniques that advance the use of molecular biological approaches, nanotechnology, immobilization, vermicomposting and genetic modification developments are investigated to take advantage of these possibilities. Volume 4: Degradation of Pesticides and Polychlorinated Biphenyls addresses pesticide degradation, PCBs degradation, and genetic interventions. It begins by describing environment pesticide degradation, mechanisms and sustainability, microbes and microbial enzymes, plant microbe interactions, organophosphorus degradations and endosulfan degradation. It then goes on to discuss PCBs and degradation, cypermethrin, degradation by Phanerochaete chrysosporium, carvone and surfactants for degradation of PCBs. The book also advocates for genetic systems for degradation of PCBs and pesticides, with discussion of the different advantages and disadvantages for each strategy and the various techniques. Together, these four volumes provide in-depth coverage of the mechanisms, advantages, and disadvantages of the bioremediation and phytoremediation technologies for safe and sustainable soil management. The diverse topics help to arm biologists, agricultural engineers, environmental and soil scientists and chemists with the information and tools they need to address soil toxins that are a dangerous risk to plants, wildlife, humans and, of course, the soil itself.

Building Stones of Milan and Lombardy - 2-Volume Set (Hardcover): Roberto Bugini, Luisa Folli Building Stones of Milan and Lombardy - 2-Volume Set (Hardcover)
Roberto Bugini, Luisa Folli
R5,520 Discovery Miles 55 200 Ships in 12 - 17 working days

Milan and Lombardy have played an important role in the Italian country since the Roman period. This importance is reflected also by the diffusion of stone architecture: a persisting trait of Milan architecture was the use of different stones in the same building. Milan lies in the middle of the alluvial plain of the Po, far from the stone quarries; some waterways were dug out in order to supply the building stones from the surrounding territories. The study of stone as building material was significant at the end of 19th century, but then it was largely neglected by both architects and geologists. So it is significant to suggest a study about the stones employed to build in Milan (Part One) in relationship with a petrographic study about the features of the stones quarried in the whole Lombard territory (Part Two). Part One contains a record of Milanese edifices, edifices marking the different historical periods. Each edifice is described in a "card" containing: the building history, the architect, the kind of stone employed and subdivided according to the different parts of the building, the shape of stone elements. Part Two contains the description of the features of the stones reported in the first part. They are metamorphic and magmatic rocks of the Alpine area; sedimentary rocks and loose materials of the Prealpine area; sedimentary rocks of the Apennine area; loose sediments of the Padania plain. Some stones, coming from other northern Italian regions, and used in Lombard architecture, are also described. Each stone is described in a "card" containing: commercial and historical names, petrographic classification, macroscopic features, mineralogical composition, microscopic features, geological setting, quarry sites, transport to yards, morphology of dressed elements and surface handworking, use in architecture in the whole Lombard territory and abroad, decay morphologies. A particular investigation is addressed to the stones used during the 20th century, a great part of them was never used before in Milan and in Lombardy.

'Date, time, wind, waves, pressure, temperature, and cloud cover. Like pilots, roofers and mountain climbers, mariners are obsessed with the weather, immersed in it as part of their daily calculus . . . Make good decisions, mariners are fond of saying. If there were a corollary to this, it might offer: When the weather gods show you their cards, don't miss them' Weather can be the difference between life and death for a sailor, something Captain Elliot Rappaport knows very well, having spent almost his whole adult life at sea. A professional ship's captain, with over thirty years of experience sailing traditional vessels, 'tall ships', Captain Rappaport has travelled around 100,000 sea miles, in all four hemispheres, and spent a great many hours watching the weather unfold. In Reading the Glass he shares all he has learned about the weather at sea, gives us an inside look at the world of seafaring, a vocation much more than a job, and shares some hard-won mariner's wisdom: if you are headed for Greenland in July, expect at least one storm, and wait until after Christmas to sail to New Zealand's South Island; pack $3000-worth of fruit and veg for a two-month journey at sea; and the most valuable member of the crew is first of all the engineer, and secondly the cook! Reading the Glass is a gorgeous blend of drily funny stories of life on a ship, the history of seafaring, stories of explorers, discoveries, epic storms, and the science of weather.

This is the most up-to-date guide to the management of coastal waters.Some of the world's most important bodies of water, from the Black Sea to the Bay of Bengal, are classified as 'semi-enclosed marine systems' (SEMS). Separated from the open seas by a strait, island archipelago, or physical process, SEMS are particularly vulnerable to environmental damage and particularly difficult to fully understand and manage."Watersheds, Bays, and Bounded Seas" provides state-of-the-science information about these complex systems and identifies best management practices to preserve them. With contributions by natural and social scientists, the book examines both the political and biophysical forces affecting semi-enclosed marine systems.SEMS comprise a substantial portion of the coasts - areas with high population density - and we rely on them for often-competing services such as navigation and transport, disposal of waste, provision of food, extraction of minerals, and leisure. The book describes how human activities could irrevocably alter these fragile ecosystems, exploring threats from runoff to climate change. It also addresses the unique challenges of managing SEMS, including cooperation between multiple nations.

‘Brilliant, clear, and humane’ Elizabeth Gilbert, author of Eat, Pray, Love ‘Miraculous and hopeful’ Emma Straub, author of All Adults Here ‘Quietly profound … belongs on the shelf next to Jon Krakauer’s Into the Wild’ New York Times Riverman: An American Odyssey uncovers the story of an extraordinary man and his puzzling disappearance, and paints a picture of the singular spirit of America’s riverbank towns. ‘The peace of mind I found, largely alone, on that white-water mecca convinced me that life was capable of exquisite pleasure and undefined meaning deep in the face of failure. The experience itself is the reward.’ Dick Conant On his forty-third birthday, Dick Conant, a golden boy who never quite grew up as those around him expected, stepped into a homemade boat to embark on a journey despite a gathering snowstorm. Among his possessions was a Gideon Bible and biographies of Einstein and Bismark. It was the beginning of an all-consuming odyssey by an unconventional man into the watery arteries of America, a journey to the unreported margins of society. He was to spend the next twenty years canoeing thousands of miles of rivers and their innumerable smaller tributaries, from one end of the country to the other. ‘I can, and I will!’ he said. And then, in 2014, he disappeared. Not long before Conant’s upturned canoe was found in a brackish North Carolina bay, Ben McGrath met Conant by chance as he paddled down the Hudson, headed for Florida. McGrath set out to find the people whose lives, like his own, had been touched by their encounter with the great river wanderer. Along the way he meets eccentrics and ne’er-do-wells drawn straight from the pages of Mark Twain, a vast network of friends and acquaintances who would forever remember this brilliant and charming man even after a single meeting. Riverman is the story of a restless soul who was as troubled as he was charismatic, a contemporary folk hero who slips the moorings of ordinary civilised life to tap into what Thoreau called ‘a yearning toward all wildness.’ It is also a riveting portrait of an America we rarely see: a nation of unconventional characters, small river towns, and long forgotten waterways.

A journey through time and around the world to uncover water's true nature, and how it can help us adapt to climate change. Trouble with water – increasingly frequent, extreme floods and droughts – is one of the first obvious signs of climate change. Meanwhile, urban sprawl, industrial agriculture and engineered water infrastructure are making things worse. As our control attempts fail, we are forced to recognize an eternal truth: sooner or later, water always wins. Award-winning science journalist Erica Gies follows water 'detectives' as they search for clues to water's past and present. Their tools: cutting-edge science and research into historical ecology, animal life, and earlier human practices. Their discoveries: a deeper understanding of what water wants and how accommodating nature can protect us and other species. Modern civilizations tend to speed water away. We have forgotten that it must flex with the rhythms of the earth, and that only collaboration with nature will allow us to forge a more resilient future.

Ecological Economics of the Oceans and Coasts (Hardcover): Murray Patterson, Bruce Glavovic Ecological Economics of the Oceans and Coasts (Hardcover)
Murray Patterson, Bruce Glavovic
R3,955 Discovery Miles 39 550 Ships in 12 - 17 working days

This timely book offers a fresh view on how oceans and coasts are, and should be, managed. The urgency of this issue is increasingly being recognized, as critical limits to the economic exploitation of our oceans and coasts are reached. The authors argue that ecological economics is in a unique position to address this problem given its particular focus on interconnected ecological and economic systems. Four 'cornerstones' of this ecological economics approach to the oceans and coasts are presented; most importantly, sustainability is the overarching policy goal, rather than economic efficiency, as I soften emphasized in mainstream economics. Secondly, recognizing the biophysical limits and thresholds of marine systems is fundamental. Thirdly, a complex systems view is adopted, which has profound implications for managing marine systems in the face of intrinsic uncertainty, irreversibility and interdependent behaviour. Finally, the approach is necessarily methodologically pluralistic, given the complexity and multi-faceted character of marine ecological-economic systems. Ecological Economics of the Oceans and Coasts is a unique book that will be warmly welcomed by ecological economists, researchers and academics of coastal and marine management and policy as well as natural resource and environmental economists. Policy advisors on oceans and coasts, coastal and marine managers will also find this book of great interest and value.

R3,746 Discovery Miles 37 460 Ships in 12 - 17 working days

* Wide coverage of soils and perennial cropping systems in the tropics * Synthesis of decades of research * Challenges assumptions on the benefits of plantations for soil fertilityIt is generally assumed that soil fertility decline is widespread in the tropics and that this is largely associated with annual cropping and subsistence farming. In contrast, perennial plant cover (as in plantation agriculture) provides better protection for the soil. This book reviews these concepts, focusing on soil chemical changes under different land-use systems in the tropics. These include perennial crops, annual crops and forest plantations. Two case studies, on sisal plantations in Tanzania and sugar cane in Papua New Guinea, are presented for detailed analysis. The author demonstrates that soil fertility decline is also a problem on plantations.
