Proceedings of the 44th Session of the International Seminars on Nuclear War and Planetary Emergencies held in Erice, Sicily. This seminar has again gathered, in 2011, over one hundred scientists in an interdisciplinary effort that has been going on for the last 31 years, to examine and analyze planetary problems which have been followed up, all year long, by the World Federation of Scientists' Permanent Monitoring Panels.

This book provides a critical overview of the relationships between planning and railway management and development during the key period in the 20th Century when the railway was in public ownership: 1948-94. It assesses the strength of the relationships when working in collaboration with the private sector. The book then focuses on the interplay between planning and railway since privatization in 1994 and points to best practice for the future in institutional structures and policy development to secure improved outcomes.

11 June, 1930. On a ship floating near Nonsuch Island, a curious steel ball is lowered 3,000 feet into the sea. Crumpled inside, the famed zoologist William Beebe gazes out of the thick quartz windows, watching luminous marine life and never-before-seen creatures flit out of the inky darkness.

A deep dive into Beebe's eyewitness accounts of underwater exploration, The Bathysphere Book blends research and storytelling, uncovering a magical world where ghostly glowing organisms test the limits of human understanding.

‘A gripping read that will anger as much as it fascinates’ Hugh Fearnley-Whittingstall ‘An incredible journey into the world of rubbish, full of fascinating characters and mind-bending facts’ Oliver Bullough, author of Moneyland   ‘Urgent, probing and endlessly interesting’ Cal Flyn, author of Islands of Abandonment 'A fascinating, deeply researched and hugely important exposé of what happens to the stuff we no longer want, and the social and environmental cost of dealing with it' Gaia Vince  ‘Compelling, smart, fair, often funny, always interesting, and just very important’ Mary Roach, author of Stiff 'There are stories in all our discarded things: who made them, what they meant to a person before they were thrown away. In the end, it all ends up in the same place – the endless ingenuity of humanity in one filthy, fascinating mass.'   When we throw things ‘away’, what does that actually mean? Where does it go, and who deals with it when it gets there? In Wasteland, award-winning journalist Oliver Franklin-Wallis takes us on an eye-opening journey through the global waste industry. From the mountainous landfills of New Delhi to Britain’s overflowing sewers, from hollowed-out mining towns in the USA to Ghana’s flooded second-hand markets, we meet the people on the frontline of our waste crisis – both those being exploited, and those determined to make a difference. On the way, we discover the corporate greenwashing that started the recycling movement; the dark truth behind our second-hand donations; and come face to face with the 10,000-year legacy of our nuclear waste.   Both shocking and hopeful, Wasteland is the timely and ultimately human story at the heart of an urgent global issue.

Over the last few decades, space exploration has revolutionised our understanding of our place in the cosmos. We now know that there are many habitable environments within our solar system. Yet a profound question remains: are we alone in the universe?

Nathalie A. Cabrol, leading astrobiologist and director of the Carl Sagan Center at the SETI Institute, takes us to the frontiers of the search for life. This book’s odyssey begins by searching for how life began on Earth in order to understand what’s necessary for life to exist elsewhere. What role did our moon play? And could life on Mars, or another world, have seeded life on Earth?

Cabrol continues this dazzling interplanetary tour, illuminating the likeliest places for life in our neighbourhood: Venus, Mars, the icy moons of Jupiter and Saturn, and Pluto. Finally, we seek life beyond our solar system, looking at the recent revolution in the night sky: the realisation that there are millions of exoplanets within our galaxy that could support life.

The Secret Life of the Universe is both a comprehensive and authoritative guide to the latest discoveries and an awe-inspiring exploration of what this means for us as humans on Earth today. It’s an exhilarating journey, perfect for anyone who has ever looked up at the stars and wondered what might be out there.

The hardcover edition includes integrated black and white illustrations throughout, and a 16-page colour plate section.

Less than 200 km north of Pretoria, the majestic Waterberg plateau rises behind formidable ramparts that have long discouraged travellers and settlers. Reputedly used by President Kruger as a conveniently remote place to exile troublesome burghers, this rugged and scenic upland remained unknown to most South Africans until its development as an exclusive eco-tourism and hunting destination in the last 25 years. Despite (perhaps because of) its prolonged isolation and sparse population from the earliest times, the Waterberg has experienced a long and vibrant history. Yet until now, this is a history that has never been recounted in comprehensive, factual detail.

Waterberg Echoes tells the stories of the remarkable people who first settled the plateau and its surrounds and their tribulations from disease, agriculture and governmental neglect. It describes conflicts during the difeqane, the South African War and the 1914 rebellion; the stories of mines in the lowlands surrounding the plateau and the arrival of Herero refugees from Namibia in 1906; the spread of religions and education across the region; and the role of politics.

Nature conservation is often framed as an ecological problem in need of repair. With both material and discursive dimensions, repairing things involves repairing people's orientation to those things. As such, nature conservation can be understood as a negotiation between different orientations to ecological problems.

This publication seeks to understand the negotiation through trust, the analysis of which situates repair in a particular setting. Empirically, the book is structured around an encounter that unfolded over the course of a single day between white commercial farmers and experts belonging to various government departments, universities and an NGO working in a South African nature reserve.

By moving through the situation sequence-by-sequence the author captures the relationship between trust and repair vis-à-vis the material forces that structured the situation, and the discursive methods that actors used to repair a degraded ecology.

This is the first textbook to cover the essential aspects of the topic at a level accessible to students. While focusing on applications in solid earth geophysics, the book also includes excursions into helioseismology, thereby highlighting the strong affinity between the two fields. The book provides a comprehensive introduction to seismic tomography, including the basic theory of wave propagation, the ray and Born approximations required for interpretation of amplitudes, and travel times and phases. It considers observational features while also providing practical recommendations for implementing numerical models. Written by one of the leaders in the field, and containing numerous student exercises, this textbook is appropriate for advanced undergraduate and graduate courses. It is also an invaluable guide for seismology research practitioners in geophysics and astronomy. Solutions to the exercises and accompanying tomographic software and documentation can be accessed online from www.cambridge.org/9780521882446.

Throughout the world, traffic levels are increasing and, in urban areas, these increasing levels have led to pressures on the road networks which are causing serious economic, environmental and social problems. This book examines the full range of 'push and pull' Travel Demand Management measures. This covers areas of regulatory, pricing, planning and persuasive policies to encourage individuals to make their trips in off-peak periods, by a different mode or to find another way of carrying out the trip purpose. Applying such measures can result in a more efficient transport system, improved environmental conditions and improvements in safety as well as revenue generation for use on alternative transport systems. The editors conclude with a summary of findings within the book and suggestions for best future practice.

Southern Africa is without equal in terms of geology, a treasure trove of valuable minerals with a geological history dating back some 3 600 million years. In addition, the evolution of plants and animals, especially mammals and dinosaurs, is well preserved in the region, which also has among the best records of the origin of modern man.

The story of earth and life provides an insight into this remarkable history – how southern Africa's mineral deposits were formed, how its life evolved and how its landscape was shaped. Along the way readers will be enthralled by accounts of the Big Bang that marked the beginning of time and matter, by drifting and colliding continents, folding and fracturing rocks, meteors colliding with the Earth, volcanic eruptions, and the start of life. Other topics include why South Africa is so rich in minerals, how glacial deposits came to be found in the Karoo, why dinosaurs became extinct, how mammals developed from reptiles, and how closely humans are related to the apes.

The answers to many such questions can be found in this title. Anyone interested in the landscape and ecosystems in which we live will be intrigued by this title.
