Energy is the only universal currency; it is necessary for getting anything done. The conversion of energy on Earth ranges from terra-forming forces of plate tectonics to cumulative erosive effects ...of raindrops. Life on Earth depends on the photosynthetic conversion of solar energy into plant biomass. Humans have come to rely on many more energy flows -- ranging from fossil fuels to photovoltaic generation of electricity -- for their civilized existence. In this monumental history, Vaclav Smil provides a comprehensive account of how energy has shaped society, from pre-agricultural foraging societies through today's fossil fuel--driven civilization. Humans are the only species that can systematically harness energies outside their bodies, using the power of their intellect and an enormous variety of artifacts -- from the simplest tools to internal combustion engines and nuclear reactors. The epochal transition to fossil fuels affected everything: agriculture, industry, transportation, weapons, communication, economics, urbanization, quality of life, politics, and the environment. Smil describes humanity's energy eras in panoramic and interdisciplinary fashion, offering readers a magisterial overview. This book is an extensively updated and expanded version of Smil'sEnergy in World History(1994). Smil has incorporated an enormous amount of new material, reflecting the dramatic developments in energy studies over the last two decades and his own research over that time.
In the twenty-first century, cities worldwide must respond to a growing and diverse population, ever-shifting economic conditions, new technologies, and a changing climate. Short-term, ...community-based projects—from pop-up parks to open streets initiatives—have become a powerful and adaptable new tool of urban activists, planners, and policy-makers seeking to drive lasting improvements in their cities and beyond. These quick, often low-cost, and creative projects are the essence of the Tactical Urbanism movement. Whether creating vibrant plazas seemingly overnight or re-imagining parking spaces as neighborhood gathering places, they offer a way to gain public and government support for investing in permanent projects, inspiring residents and civic leaders to experience and shape urban spaces in a new way. Tactical Urbanism, written by Mike Lydon and Anthony Garcia, two founders of the movement, promises to be the foundational guide for urban transformation. The authors begin with an in-depth history of the Tactical Urbanism movement and its place among other social, political, and urban planning trends. A detailed set of case studies, from guerilla wayfinding signs in Raleigh, to pavement transformed into parks in San Francisco, to a street art campaign leading to a new streetcar line in El Paso, demonstrate the breadth and scalability of tactical urbanism interventions. Finally, the book provides a detailed toolkit for conceiving, planning, and carrying out projects, including how to adapt them based on local needs and challenges. Tactical Urbanism will inspire and empower a new generation of engaged citizens, urban designers, land use planners, architects, and policymakers to become key actors in the transformation of their communities.
How cities can build on the “sharing economy” and smart technology to deliver a “sharing paradigm” that supports justice, solidarity, and sustainability.
The future of humanity is urban, and the ...nature of urban space enables, and necessitates, sharing—of resources, goods and services, experiences. Yet traditional forms of sharing have been undermined in modern cities by social fragmentation and commercialization of the public realm. In Sharing Cities, Duncan McLaren and Julian Agyeman argue that the intersection of cities' highly networked physical space with new digital technologies and new mediated forms of sharing offers cities the opportunity to connect smart technology to justice, solidarity, and sustainability. McLaren and Agyeman explore the opportunities and risks for sustainability, solidarity, and justice in the changing nature of sharing.
McLaren and Agyeman propose a new “sharing paradigm,” which goes beyond the faddish “sharing economy”—seen in such ventures as Uber and TaskRabbit—to envision models of sharing that are not always commercial but also communal, encouraging trust and collaboration. Detailed case studies of San Francisco, Seoul, Copenhagen, Medellín, Amsterdam, and Bengaluru (formerly Bangalore) contextualize the authors' discussions of collaborative consumption and production; the shared public realm, both physical and virtual; the design of sharing to enhance equity and justice; and the prospects for scaling up the sharing paradigm though city governance. They show how sharing could shift values and norms, enable civic engagement and political activism, and rebuild a shared urban commons. Their case for sharing and solidarity offers a powerful alternative for urban futures to conventional “race-to-the-bottom” narratives of competition, enclosure, and division.
Water lies at the intersection of landscape and infrastructure, crossing between visible and invisible domains of urban space, in the tanks and buckets of the global South and the vast subterranean ...technological networks of the global North. In this book, Matthew Gandy considers the cultural and material significance of water through the experiences of six cities: Paris, Berlin, Lagos, Mumbai, Los Angeles, and London. Tracing the evolving relationships among modernity, nature, and the urban imagination, from different vantage points and through different periods, Gandy uses water as a lens through which to observe both the ambiguities and the limits of nature as conventionally understood. Gandy begins with the Parisian sewers of the nineteenth century, captured in the photographs of Nadar, and the reconstruction of subterranean Paris. He moves on to Weimar-era Berlin and its protection of public access to lakes for swimming, the culmination of efforts to reconnect the city with nature. He considers the threat of malaria in Lagos, where changing geopolitical circumstances led to large-scale swamp drainage in the 1940s. He shows how the dysfunctional water infrastructure of Mumbai offers a vivid expression of persistent social inequality in a postcolonial city. He explores the incongruous concrete landscapes of the Los Angeles River. Finally, Gandy uses the fictional scenario of a partially submerged London as the starting point for an investigation of the actual hydrological threats facing that city.

This open access book develops a framework for advancing agroecology transformations focusing on power, politics and governance. It explores the potential of agroecology as a sustainable and socially ...just alternative to today’s dominant food regime. Agroecology is an ecological approach to farming that addresses climate change and biodiversity loss while contributing to the Sustainable Development Goals. Agroecology transformations represent a challenge to the power of corporations in controlling food system and a rejection of the industrial food systems that are at the root of many social and ecological ills. In this book the authors analyse the conditions that enable and disable agroecology’s potential and present six ‘domains of transformation’ where it comes into conflict with the dominant food system. They argue that food sovereignty, community-self organization and a shift to bottom-up governance are critical for the transformation to a socially just and ecologically viable food system. This book will be a valuable resource to researchers, students, policy makers and professionals across multidisciplinary areas including in the fields of food politics, international development, sustainability and resilience.
