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 How to Design Wastewater Systems for Local Conditions in Developing Countries by : David M. Robbins
Download or read book How to Design Wastewater Systems for Local Conditions in Developing Countries written by David M. Robbins and published by IWA Publishing. This book was released on 2014-03-15 with total page 148 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is a practical handbook providing a step-by-step approach to the techniques used for characterizing wastewater sources and investigating sites where collection, treatment and reuse/disposal technologies will be installed. It is intended to help enable local implementation of on-site and decentralized wastewater management system (DWMS)for wide scale use in development settings. How to Design Wastewater Systems for Local Conditions in Developing Countries helps local service providers and regulatory officials make informed decisions through the use of tools, checklists and case studies. It includes a link to a web based community of on-site and decentralized wastewater professionals, which contains related tools and case studies. This handbook serves as a reference for training classes, certification programs, and higher education programs in civil and sanitary engineering. There is an increasing interest on the part of local government officials and private sector service providers to implement wastewater treatment systems to solve sanitation problems. The model presented in this handbook promotes activities that first generate data related to source and site conditions that represent critical inputs, and then applies this information to the technology selection process. Matching the most appropriate technologies to the specific needs of the wastewater project is the key that leads to long term sustainability. How to Design Wastewater Systems for Local Conditions in Developing Countries is an invaluable resource for public sector decision makers and private sector service providers in developing countries. It is also a useful text for students at engineering colleges in developing countries interested in taking a class that teaches the methods of decentralized wastewater management system (DWMS) development.
Book Synopsis Fiscal Disobedience by : Janet Roitman
Download or read book Fiscal Disobedience written by Janet Roitman and published by Princeton University Press. This book was released on 2005 with total page 260 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fiscal Disobedience represents a novel approach to the question of citizenship amid the changing global economy and the fiscal crisis of the nation-state. Focusing on economic practices in the Chad Basin of Africa, Janet Roitman combines thorough ethnographic fieldwork with sophisticated analysis of key ideas of political economy to examine the contentious nature of fiscal relationships between the state and its citizens. She argues that citizenship is being redefined through a renegotiation of the rights and obligations inherent in such economic relationships. The book centers on a civil disobedience movement that arose in Cameroon beginning in 1990 ostensibly to counter state fiscal authority--a movement dubbed Opération Villes Mortes by the opposition and incivisme fiscal by the government (which for its part was eager to suggest that participants were less than legitimate citizens, failing in their civic duties). Contrary to standard approaches, Roitman examines this conflict as a "productive moment" that, rather than involving the outright rejection of regulatory authority, questioned the intelligibility of its exercise. Although both militarized commercial networks (associated with such activities trading in contraband goods including drugs, ivory, and guns) and highly organized gang-based banditry do challenge state authority, they do not necessarily undermine state power. Contrary to depictions of the African state as "weak" or "failed," this book demonstrates how the state in Africa manages to reconstitute its authority through networks that have emerged in the interstices of the state system. It also shows how those networks partake of the same epistemological grounding as does the state. Indeed, both state and nonstate practices of governing refer to a common "ethic of illegality," which explains how illegal activities are understood as licit or reasonable conduct.

Book Synopsis Kwame Nkrumah 1909-1972 by : Bea Lundt
Download or read book Kwame Nkrumah 1909-1972 written by Bea Lundt and published by Franz Steiner Verlag Wiesbaden GmbH. This book was released on 2016 with total page 208 pages. Available in PDF, EPUB and Kindle. Book excerpt: In 1957, Ghana was the first sub-Saharan country in Africa to achieve independence. The key African figure in this process was Kwame Nkrumah, the first president of the new state. Having studied in the USA and in London he was influenced by socialist and pan-African ideals. His ambitious projects in the fields of education and scientific as well as technological development provided an example for other former colonies. But in 1966 he was overthrown by a military coup supported by the USA and died in exile in 1972. Fifty years later, his memory is omnipresent in Ghanaian society and in other African countries. Still, his achievements are a subject of controversy. Was he a hero of the anti-colonial struggle or an authoritarian dictator? This volume presents chapters by researchers from Ghana, Austria, Germany, and the USA. They analyse the visionary politics of Nkrumah, investigate the reasons for the growing protest against his rule and shed new light on the background of the coup. The last part is dedicated to questions of evaluation and memory. Fifty years after his fall from power, new research and distance from the events allow for a more balanced judgment of Nkrumah.

Book Synopsis Modifications hydrodynamiques du comportement des métaux lourds dans un sol hétérogène présentant une contamination résiduelle en NAPL by : Jean-Sébastien Dubé
Download or read book Modifications hydrodynamiques du comportement des métaux lourds dans un sol hétérogène présentant une contamination résiduelle en NAPL written by Jean-Sébastien Dubé and published by . This book was released on 2001 with total page 235 pages. Available in PDF, EPUB and Kindle. Book excerpt: La contamination mixte des sols par les dérivés organiques pétroliers et les métaux lourds est une situation répandue et problématique dans les zones urbaines et industrialisées. Toutefois, aucun travail ne s'était penché, à ce jour, sur le rôle joué au sein de ce type de contamination par les interactions entre les métaux lourds et les liquides organiques non miscibles (NAPL). Les objectifs de la présente étude ont été de 1) vérifier la présence d'une influence des NAPL résiduels sur le transfert métallique dans les sols, 2) déterminer la nature de cette influence et 3) caractériser les mécanismes qui la déterminent. Les travaux entrepris ont permis d'identifier et de mesurer à l'échelle du laboratoire, à l'aide de colonnes de sol, les mécanismes d'interaction NAPL-métaux dans les sols. Un premier volet expérimental a servi à identifier la nature des interactions NAPL-métaux et à proposer leurs mécanismes sous-jacents. Un second volet expérimental a permis de quantifier les mécanismes d'influence du NAPL résiduel sur l'écoulement aqueux par modélisation mathématique. Les résultats de modélisation de l'écoulement aqueux ont ensuite été utilisés afin d'analyser les modifications du transfert des métaux lourds. Les résultats ont montré que les NAPL résiduels peuvent modifier le transfert des métaux lourds en altérant les conditions hydrodynamiques au sein du sol. La présence de NAPL résiduel a accentué l'hétérogénéité du réseau poreux en déconnectant les chenaux préférentiels et les micropores. Ceci a eu pour résultat de confiner la phase aqueuse au sein des chenaux préférentiels. En conséquence, ceci a modifié la capacité du sol à atténuer le flux métallique infiltrant. Les résultats ont aussi souligné le rôle de certains paramètres importants sur l'impact des NAPL résiduels sur le transfert des métaux lourds, notamment la viscosité du NAPL, les conditions hydriques initiales du sol et de la vitesse d'écoulement aqueux.
