Cities In Layers

Perch on top of a skyscraper with the Stickmen, then descend to street level and travel below to see all the layers of a city. But beware, some layers are smellier than others! Follow the Stickmen to land on a helipad, ride in a double-decker underground subway, and view a giant lump of fat in a sewer. The Stickmen unveil the hidden systems that keep a city lit up, networked, and clean, and reveal fascinating facts and statistics along the way.

Explores the atmospheric layers that wrap around Earth, and explains how each layer has a different effect on the way we live on Earth.

Named a Best Book of the Year by NPR and Science Friday A quest to explore some of the most spectacular ancient cities in human history—and figure out why people abandoned them. In Four Lost Cities, acclaimed science journalist Annalee Newitz takes readers on an entertaining and mind-bending adventure into the deep history of urban life. Investigating across the centuries and around the world, Newitz explores the rise and fall of four ancient cities, each the center of a sophisticated civilization: the Neolithic site of Çatalhöyük in Central Turkey, the Roman vacation town of Pompeii on Italy’s southern coast, the medieval megacity of Angkor in Cambodia, and the indigenous metropolis Cahokia, which stood beside the Mississippi River where East St. Louis is today. Newitz travels to all four sites and investigates the cutting-edge research in archaeology, revealing the mix of environmental changes and political turmoil that doomed these ancient settlements. Tracing the early development of urban planning, Newitz also introduces us to the often anonymous workers—slaves, women, immigrants, and manual laborers—who built these cities and created monuments that lasted millennia. Four Lost Cities is a journey into the forgotten past, but, foreseeing a future in which the majority of people on Earth will be living in cities, it may also reveal something of our own fate.

Presents a modern and interdisciplinary perspective on cities that combines new data with tools from statistical physics and urban economics.

Contemporary cities face phenomenal risks, and they face particularly high levels of mounting social and environmental risks, including social polarization, urban conflicts, riots, terror, and climate change threats. This book suggests that climate change and its resulting uncertainties challenge the concepts, procedures, and scope of conventional approaches to planning, creating a need to rethink and revise current planning methods. Therefore, this book suggests a paradigm shift in our thinking, interrogation, and planning of our cities. Based on the contemporary conditions of risk at cities, this book conceptualizes the risk city as a construct of three interlinked concepts of risk, trust, and practice. It is a construct of risk and its new evolving conditions and knowledge of uncertainties stem from climate change and other risks and uncertainties. As a construct of practices, the risk city produces social and political institutional framework and promotes practices accordingly in order to reduce risk and risk possibilities and to increase trust. In light of the complex challenges and risks to the human habitat that have emerged in recent years, many cities have prepared various types of plans aimed at addressing the challenges posed by climate change. Nonetheless, despite the importance of these plans and the major public resources invested in their formulation, we still know little about them and have yet to begin studying them and assessing their contributions . From the innovative perspective of the risk city, this book asks critical questions about the nature, vision, practices, and potential impact of the recent climate change-oriented plans. What kinds of risks do they attempt to address, what types of practices do they institute, and what types of approaches do they apply? Do they adequately address the risks and uncertainties posed? How do they contribute to the worldwide effort to reduce greenhouse gas emissions? This book uses the methodologically innovative Risk City framework to examine the nature, vision, outcomes, practices, and impact of these crucial plans, as well as their contribution to the resilience of our cities and to global efforts toward reducing greenhouse gas emissions.

Imagine waking up to the gentle noises of the city, and moving through your day with complete confidence that you will get where you need to go quickly and efficiently. Soft City is about ease and comfort, where density has a human dimension, adapting to our ever-changing needs, nurturing relationships, and accommodating the pleasures of everyday life. How do we move from the current reality in most cites—separated uses and lengthy commutes in single-occupancy vehicles that drain human, environmental, and community resources—to support a soft city approach? In Soft City David Sim, partner and creative director at Gehl, shows how this is possible, presenting ideas and graphic examples from around the globe. He draws from his vast design experience to make a case for a dense and diverse built environment at a human scale, which he presents through a series of observations of older and newer places, and a range of simple built phenomena, some traditional and some totally new inventions. Sim shows that increasing density is not enough. The soft city must consider the organization and layout of the built environment for more fluid movement and comfort, a diversity of building types, and thoughtful design to ensure a sustainable urban environment and society. Soft City begins with the big ideas of happiness and quality of life, and then shows how they are tied to the way we live. The heart of the book is highly visual and shows the building blocks for neighborhoods: building types and their organization and orientation; how we can get along as we get around a city; and living with the weather. As every citizen deals with the reality of a changing climate, Soft City explores how the built environment can adapt and respond. Soft City offers inspiration, ideas, and guidance for anyone interested in city building. Sim shows how to make any city more efficient, more livable, and better connected to the environment.
