Download or read book La gestion publique des déchets solides à Yaoundé written by Joel Sotamenou and published by Editions Universitaires Europeennes. This book was released on 2012-08 with total page 316 pages. Available in PDF, EPUB and Kindle. Book excerpt: L'urbanisation et le developpement economique ont generalement pour corollaire une augmentation de la production des dechets par habitant, et un accroissement des besoins alimentaires. Il devient donc imperatif de mettre en place, surtout dans les villes africaines, un systeme de gestion des dechets solides qui pourrait favoriser le developpement de l'agriculture urbaine et periurbaine. Dans cet ouvrage, nous analysons les limites de l'organisation du service public de gestion des dechets solides a Yaounde, d'une part, et apprehendons la pertinence du compostage dans un systeme alternatif de gestion des dechets solides au Cameroun, d'autre part. Il ressort globalement de nos analyses que le service public de gestion des dechets solides a Yaounde est sous-performant. Soucieux de prendre en compte les preoccupations de developpement socio-economique et environnemental de la ville de Yaounde, nous proposons un systeme alternatif des dechets solides qui comprend les operations de precollecte, de compostage, de collecte et de transport, d'enfouissement, de traitement des lixiviats et de biogaz.
Book Synopsis Déchets solides ménagers de la ville de Yaoundé (Cameroun) by : Jules Raymond Ngambi

Available in PDF, EPUB and Kindle. Book excerpt: Pour comprendre la gestion des déchets à Yaoundé, deux angles d'analyse ont été abordés. Il s'agit de la gestion linéaire basée sur les stratégies de collecte, de transport, de traitement, de mise en décharge des déchets et de la transition vers une économie circulaire. Le chevauchement des pouvoirs, les insuffisances organisationnelles, techniques et managériales à Yaoundé sont à l'origine d'inégalités environnementales et d'accès au service public de déchet. Ceci a engendré les risques et nuisances comme la prolifération des dépôts sauvages, les incinérations à ciel ouvert, les inondations et les pathologies liées aux déchets.Les limites de la gestion linéaire ont amené les pouvoirs publics à poser à partir de 1992 les bases d'un nouveau système basé sur le recyclage des déchets appelé aujourd'hui sous le vocable international économie circulaire. Celle-ci se développe sur le terrain à travers les filières formelles et informelles de récupération, de réparation, de réemploi/réutilisation, d'achat et de revente des déchets, de compostage et de recyclage. Cette stratégie gouvernementale, appuyée par les acteurs de la société civile et privés, se structure depuis 2010 par la création de nouvelles filières comme le projet de méthanisation à la décharge de Nkol Foulou, le recyclage des déchets d'équipements électriques et électroniques et l'adoption en 2012 d'un cadre juridique sur l'économie du déchet. L'activité de la réparation connait un dynamisme qu'il serait important de structurer. Mais la perception négative du déchet par les populations freine encore l'essor de ce domaine d'activités. D'où la nécessité de sensibiliser, d'informer et d'éduquer les yaoundéens afin d'améliorer la gestion des déchets.

This book was released on 2006 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: L'EVALUATION DES INCIDENCES ENVIRONNEMENTALES ET ECONOMIQUES DES SYSTEMES DE GESTION DES DECHETS URBAINS CONSTITUE L'OBJECTIF DE CE TRAVAIL. LE CAS DE LA VILLE DE YAOUNDE AU CAMEROUN A ETE SPECIFIQUEMENT ANALYSE. QUATRE SYSTEMES DE GESTION ONT SERVI DE BASE AUX ANALYSES EFFECTUEES. LE SYSTEME 1 EST CONSTITUE PAR LA COLLECTE TRADITIONNELLE ET LA MISE EN DECHARGE DES DECHETS BRUTS ; DANS LE SYSTEME 2 LE BIOGAZ QUI EST PRODUIT APRES LA MISE EN DECHARGE EST RECUPERE POUR PRODUIRE DE L'ELECTRICITE ; LES SYSTEMES 3 ET 4, CONSIDERENT APRES LA COLLECTE, UNE ETAPE DE TRAITEMENT PAR COMPOSTAGE ET METHANISATION EN REACTEUR ET DE LA MISE EN DECHARGE DES DECHETS ULTIMES. LA METHODE D'ANALYSE DE CYCLE DE VIE (ACV), A ETE UTILISEE POUR EVALUER CES QUATRE SYSTEMES. POUR CELA, LES ETAPES SUIVANTES ONT ETE ETUDIEES : LA COLLECTE, LE TRANSPORT, LE TRAITEMENT, LE TRANSPORT DES SOUS PRODUITS SUR UNE DISTANCE DE 70 KM, LA MISE EN DECHARGE DES RESIDUS. L'ANALYSE DES DIFFERENTS REJETS A PERMIS DE RECENSER SIX CLASSES D'IMPACT POUR LES SYSTEMES DE GESTION DES DECHETS ETUDIES. CES CLASSES D'IMPACT CONSTITUENT LES CRITERES ENVIRONNEMENTAUX PERTINENTS POUR L'EVALUATION ENVIRONNEMENTALE DES QUATRE SYSTEMES EN UTILISANT LES OUTILS D'ANALYSE MULTICRITERE. AINSI, SUR LE PLAN ENVIRONNEMENTAL, LE SYSTEME 2 SE DEGAGE COMME LE PLUS PERFORMANT. A L'ANALYSE ENVIRONNEMENTALE DE CES ETAPES S'AJOUTE UNE EVALUATION ECONOMIQUE BASEE SUR DEUX CRITERES A SAVOIR LES COUTS DES INVESTISSEMENTS ET LES COUTS DE GESTION. LA ENCORE, LE SYSTEME 2 APPARAIT COMME LE PLUS ECONOMIQUE, CONTRAIREMENT AUX SYSTEMES 3 ET 4 QUI NECESSITENT UN INVESTISSEMENT 5 A 10 FOIS PLUS ELEVE POUR LEUR MISE EN UVRE ET UN COUT DE GESTION 2 A 3 FOIS PLUS ELEVES. LE SYSTEME 2 SE DEGAGE COMME LE PLUS PERFORMANT D'UN POINT DE VUE ENVIRONNEMENTAL ET ECONOMIQUE DANS LE CONTEXTE DE YAOUNDE. IL S'AVERE AINSI PREFERABLE DE RAMASSER LES DECHETS EN VRAC, DE LES METTRE EN DECHARGE ET PAR LA SUITE DE RECUPERER LE BIOGAZ QUI EST PRODUIT.
Book Synopsis Beyond the Networked City by : Olivier Coutard
Download or read book Beyond the Networked City written by Olivier Coutard and published by Routledge. This book was released on 2015-12-14 with total page 256 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cities around the world are undergoing profound changes. In this global era, we live in a world of rising knowledge economies, digital technologies, and awareness of environmental issues. The so-called "modern infrastructural ideal" of spatially and socially ubiquitous centrally-governed infrastructures providing exclusive, homogeneous services over extensive areas, has been the standard of reference for the provision of basic essential services, such as water and energy supply. This book argues that, after decades of undisputed domination, this ideal is being increasingly questioned and that the network ideology that supports it may be waning. In order to begin exploring the highly diverse, fluid and unstable landscapes emerging beyond the networked city, this book identifies dynamics through which a ‘break’ with previous configurations has been operated, and new brittle zones of socio-technical controversy through which urban infrastructure (and its wider meaning) are being negotiated and fought over. It uncovers, across a diverse set of urban contexts, new ways in which processes of urbanization and infrastructure production are being combined with crucial sociopolitical implications: through shifting political economies of infrastructure which rework resource distribution and value creation; through new infrastructural spaces and territorialities which rebundle socio-technical systems for particular interests and claims; and through changing offsets between individual and collective appropriation, experience and mobilization of infrastructure. With contributions from leading authorities in the field and drawing on theoretical advances and original empirical material, this book is a major contribution to an ongoing infrastructural turn in urban studies, and will be of interest to all those concerned by the diverse forms and contested outcomes of contemporary urban change across North and South.

Cities are pivotal to sustainability concerns globalization, climate change, food security, environmental protection, and innovation.Today's urban actors, both citizens and their leaders, have a major responsibility as trustees of the future: their present actions will influence the shape and structure of cities, so that the generation to come may live healthy and contended lives.This volume takes the reader straight to the heart of how cities work, and identifies contemporary trends, mechanism and tools that can influence current strategies and choices.The authors show that urbanization is not a problem per se for sustainable development, but rather that cities, in all their diversity and complexity, offer solutions as well as challenges.The reader will be inspired by vital analyses of the next decade's windows of opportunity for sustainable urban growth.
Book Synopsis In the Nature of Cities by : Nik Heynen
Download or read book In the Nature of Cities written by Nik Heynen and published by Routledge. This book was released on 2006-03-23 with total page 292 pages. Available in PDF, EPUB and Kindle. Book excerpt: The social and material production of urban nature has recently emerged as an important area in urban studies, human/environmental interactions and social studies. This has been prompted by the recognition that the material conditions that comprise urban environments are not independent from social, political, and economic processes, or from the cultural construction of what constitutes the ‘urban’ or the ‘natural’. Through both theoretical and empirical analysis, this groundbreaking collection offers an integrated and relational approach to untangling the interconnected processes involved in forming urban landscapes. The essays in this book attest that the re-entry of the ecological agenda into urban theory is vital both in terms of understanding contemporary urbanization processes, and of engaging in a meaningful environmental politics. They debate the central themes of whose nature is, or becomes, urbanized, and the uneven power relations through which this socio-metabolic transformation takes place. Including urban case studies, international research and contributions from prominent urban scholars, this volume will enable students, scholars and researchers of geographical, environmental and urban studies to better understand how interrelated, everyday economic, political and cultural processes form and transform urban environments.

Book Synopsis Faecal Sludge Management by : Linda Strande
Download or read book Faecal Sludge Management written by Linda Strande and published by IWA Publishing. This book was released on 2014-08-15 with total page 428 pages. Available in PDF, EPUB and Kindle. Book excerpt: It is estimated that literally billions of residents in urban and peri-urban areas of Africa, Asia, and Latin America are served by onsite sanitation systems (e.g. various types of latrines and septic tanks). Until recently, the management of faecal sludge from these onsite systems has been grossly neglected, partially as a result of them being considered temporary solutions until sewer-based systems could be implemented. However, the perception of onsite or decentralized sanitation technologies for urban areas is gradually changing, and is increasingly being considered as long-term, sustainable options in urban areas, especially in low- and middle-income countries that lack sewer infrastructures. This is the first book dedicated to faecal sludge management. It compiles the current state of knowledge of the rapidly evolving field of faecal sludge management, and presents an integrated approach that includes technology, management, and planning based on Sandecs 20 years of experience in the field. Faecal Sludge Management: Systems Approach for Implementation and Operation addresses the organization of the entire faecal sludge management service chain, from the collection and transport of sludge, and the current state of knowledge of treatment options, to the final end use or disposal of treated sludge. The book also presents important factors to consider when evaluating and upscaling new treatment technology options. The book is designed for undergraduate and graduate students, and engineers and practitioners in the field who have some basic knowledge of environmental and/or wastewater engineering.
Book Synopsis Stealth of Nations by : Robert Neuwirth
Download or read book Stealth of Nations written by Robert Neuwirth and published by Anchor. This book was released on 2012-10-02 with total page 306 pages. Available in PDF, EPUB and Kindle. Book excerpt: An eye-opening account of the informal economy around the globe, Stealth of Nations traces the history and reach of unregulated markets, and explains the unwritten rules that govern them. Journalist Robert Neuwirth joins globe-trotting Nigerians who sell Chinese cell phones and laid-off San Franciscans who use Twitter to market street food and learns that the people who work in informal economies are entrepreneurs who provide essential services and crucial employment. Dubbing this little-recognized business arena with a new name—”System D”—Neuwirth points out that it accounts for a growing amount of trade, and that, united in a single nation, it would be the world’s second-largest economy, trailing only the United States in financial might. Stealth of Nations offers an inside look at the thriving world of unfettered trade and finds far more than a chaotic emporium of dubious pirated goods.

Available in PDF, EPUB and Kindle. Book excerpt: In The System of Professions Andrew Abbott explores central questions about the role of professions in modern life: Why should there be occupational groups controlling expert knowledge? Where and why did groups such as law and medicine achieve their power? Will professionalism spread throughout the occupational world? While most inquiries in this field study one profession at a time, Abbott here considers the system of professions as a whole. Through comparative and historical study of the professions in nineteenth- and twentieth-century England, France, and America, Abbott builds a general theory of how and why professionals evolve.
