Available in PDF, EPUB and Kindle. Book excerpt: Infrastructure—electricity, telecommunications, roads, water, and sanitation—are central to people’s lives. Without it, they cannot make a living, stay healthy, and maintain a good quality of life. Access to basic infrastructure is also a key driver of economic development. This report lays out a framework for understanding infrastructure resilience - the ability of infrastructure systems to function and meet users’ needs during and after a natural hazard. It focuses on four infrastructure systems that are essential to economic activity and people’s well-being: power systems, including the generation, transmission, and distribution of electricity; water and sanitation—especially water utilities; transport systems—multiple modes such as road, rail, waterway, and airports, and multiple scales, including urban transit and rural access; and telecommunications, including telephone and Internet connections.

Book excerpt: Official figures classify some fifty million of the world’s people as 'victims of forced displacement'. Refugees, asylum seekers, disaster victims, the internally displaced and the temporarily tolerated - categories of the excluded proliferate, but many more are left out of count. In the face of this tragedy, humanitarian action increasingly seems the only possible response. On the ground, however, the 'facilities' put in place are more reminiscent of the logic of totalitarianism. In a situation of permanent catastrophe and endless emergency, 'undesirables' are kept apart and out of sight, while the care dispensed is designed to control, filter and confine. How should we interpret the disturbing symbiosis between the hand that cares and the hand that strikes? After seven years of study in the refugee camps, Michel Agier reveals their 'disquieting ambiguity' and stresses the imperative need to take into account forms of improvisation and challenge that are currently transforming the camps, sometimes making them into towns and heralding the emergence of political subjects. A radical critique of the foundations, contexts, and political effects of humanitarian action.

Available in PDF, EPUB and Kindle. Book excerpt: This book addresses the practice of social innovation, which is currently very much in the public eye. New ideas and approaches are needed to tackle the severe and wicked problems with which contemporary societies are struggling. Especially in times of economic crisis, social innovation is regarded as one of the crucial elements needed to move forward. Our knowledge of its dynamics has significantly progressed, thanks to an abundance of studies on social innovation both general and sector-specific. However, despite the valuable research conducted over the past years, the systematic analysis of social innovation is still contested and incomplete. The questions asked in the book will be the following: 1. What is the nature of social innovations? 2.What patterns can be identified in social innovations emerging at the local level? 3.How is the emergence and spread of social innovations related to urban governance? More precisely, which conditions and arrangements facilitate and hinders social innovation? We explore these questions using different types of data and methods, and studying different contexts. In particular, we focus on innovations that aim at solving problems of the young unemployed, single parents and migrants. This analysis is based on original research carried out in the period 2010-2013 in the framework of a European project with a specific empirical research strategy. Research was carried out in 20 cities in 10 different European countries.

This book was released on 2012 with total page 298 pages. Available in PDF, EPUB and Kindle. Book excerpt: This Thematic Study is a joint venture between ICOMOS, the advisory body to UNESCO on cultural sites, and the International Astronomical Union. It presents an overall vision on astronomical heritage, attempts to identify what constitutes "outstanding universal significance to humankind" in relation to astronomy, and identifies broad issues that could arise in the assessment of cultural properties relating to astronomy. This is the first Thematic Study in any field of science heritage. It is elaborated using examples of properties from around the world, including some already on the World Heritage List or national Tentative Lists. The subject matter ranges from early prehistory to modern astrophysics and space heritage, and also prominently includes dark sky issues and modern observatory sites. An e-version of the Thematic Study was published in June 2010 in time to be presented to the 2010 meeting of UNESCO's World Heritage Committee, where it was duly approved. It has been circulated officially by the WHC to all of UNESCO's National Commissions. This full-colour paperback edition with some updates, and reformatted to new ICOMOS standards, was published in 2011 and is now offered for public sale.

Book excerpt: Three decades after his death, Michel Foucault remains one of the towering intellectual figures of the last half-century. His works on sexuality, madness, the prison, and medicine are enduring classics. From 1971 until his death in 1984, Foucault gave public lectures at the famous Collge de France. These seminal events, attended by thousands, created the benchmarks for contemporary social enquiry. The lectures comprising Abnormal begin by examining the role of psychiatry in modern criminal justice, and its method of categorising individuals who "resemble their crime before they commit it." Building on the themes of societal self-defence developed in earlier works, Foucault shows how defining "normality" became a prerogative of power in the nineteenth century, shaping the institutions-from the prisons to the family-meant to deal with "monstrosity," whether sexual, physical, or spiritual. The Collge de France lectures add immeasurably to our appreciation and understanding of Foucault's thought.

Book excerpt: Michel de Certeau considers the uses to which social representation and modes of social behavior are put by individuals and groups, describing the tactics available to the common man for reclaiming his own autonomy from the all-pervasive forces of commerce, politics, and culture. In exploring the public meaning of ingeniously defended private meanings, de Certeau draws on an immense theoretical literature in analytic philosophy, linguistics, sociology, semiology, and anthropology--to speak of an apposite use of imaginative literature.

Book excerpt: Community and participation have become central concepts in the nomination processes surrounding heritage, intersecting time and again with questions of territory. In this volume, anthropologists and legal scholars from France, Germany, Italy and the USA take up questions arising from these intertwined concerns from diverse perspectives: How and by whom were these concepts interpreted and re-interpreted, and what effects did they bring forth in their implementation? What impact was wielded by these terms, and what kinds of discursive formations did they bring forth? How do actors from local to national levels interpret these new components of the heritage regime, and how do actors within heritage-granting national and international bodies work it into their cultural and political agency? What is the role of experts and expertise, and when is scholarly knowledge expertise and when is it partisan? How do bureaucratic institutions translate the imperative of participation into concrete practices? Case studies from within and without the UNESCO matrix combine with essays probing larger concerns generated by the valuation and valorization of culture.

Available in PDF, EPUB and Kindle. Book excerpt: Henri Lefebvre has considerable claims to be the greatest living philosopher. His work spans some sixty years and includes original work on a diverse range of subjects, from dialectical materialism to architecture, urbanism and the experience of everyday life. The Production of Space is his major philosophical work and its translation has been long awaited by scholars in many different fields. The book is a search for a reconciliation between mental space (the space of the philosophers) and real space (the physical and social spheres in which we all live). In the course of his exploration, Henri Lefebvre moves from metaphysical and ideological considerations of the meaning of space to its experience in the everyday life of home and city. He seeks, in other words, to bridge the gap between the realms of theory and practice, between the mental and the social, and between philosophy and reality. In doing so, he ranges through art, literature, architecture and economics, and further provides a powerful antidote to the sterile and obfuscatory methods and theories characteristic of much recent continental philosophy. This is a work of great vision and incisiveness. It is also characterized by its author's wit and by anecdote, as well as by a deftness of style which Donald Nicholson-Smith's sensitive translation precisely captures.

Available in PDF, EPUB and Kindle. Book excerpt: Many countries around the world are engaged in decentralization processes, and most African countries face serious problems with forest governance, from benefits sharing to illegality and sustainable forest management. This book summarizes experiences to date on the extent and nature of decentralization and its outcomes - most of which suggest an underperformance of governance reforms - and explores the viability of different governance instruments in the context of weak governance and expanding commercial pressures over forests. Findings are grouped into two thematic areas: decentralization, livelihoods and sustainable forest management; and international trade, finance and forest sector governance reforms. The authors examine diverse forces shaping the forest sector, including the theory and practice of decentralization, usurpation of authority, corruption and illegality, inequitable patterns of benefits capture and expansion of international trade in timber and carbon credits, and discuss related outcomes on livelihoods, forest condition and equity. The book builds on earlier volumes exploring different dimensions of decentralization and perspectives from other world regions, and distills dimensions of forest governance that are both unique to Africa and representative of broader global patterns. The authors ground their analysis in relevant theory while drawing out implications of their findings for policy and practice.
