This book was released on 2022-11-03 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cet ouvrage traite du choix d'approvisionnement en eau potable dans les pays en développement, en particulier dans le cas du Cameroun, où, l'accès à l'eau potable est un problème majeur pour de nombreux ménages. En abordant cette question, l'auteur souligne que la plupart des études utilisant des données primaires et/ou secondaires se sont concentrées sur les caractéristiques socioéconomiques (revenu, taille du ménage, niveau d'éducation, etc.), les sources d'eau (distance, prix au mètre cube, qualité et fiabilité) pour examiner les décisions des ménages concernant les choix d'approvisionnement en eau potable. Cependant, dans le contexte camerounais, peu d'études ont porté sur l'influence des facteurs sociodémographiques et des caractéristiques d'habitat des ménages sur la décision du choix du mode d'approvisionnement en eau potable, et il n'y a pas de consensus dans la littérature. L'auteur identifie les déterminants de l'accès des ménages à diverses sources d'eau améliorée, ce qui non seulement enrichit la littérature, mais contribue également aux décisions de politiques publiques au Cameroun en particulier et en Afrique en général.
Download or read book L impact du changement climatique sur le co t de l eau potable written by Edmond Noubissi Domguia and published by L'Harmattan. This book was released on 2021-06-04 with total page 204 pages. Available in PDF, EPUB and Kindle. Book excerpt: L'ouvrage montre que le changement climatique détériore la qualité de l'eau potable à travers l'accroissement de la quantité de sel dans les réserves d'eau douce de la ville de Douala. Cette dégradation va entraîner des coûts supplémentaires de traitement de l'eau potable par rapport au schéma classique de potabilisation de l'eau dans cette ville. Ainsi, le déficit entre l'offre et la demande en eau potable à Douala pourrait nécessiter, entre autres mesures, la construction ou l'amélioration des infrastructures de stockage de l'eau.
Download or read book Valeur de l approvisionnement en eau potable au Cameroun written by Patrick Arnold Ombiono Kitoto and published by Editions Universitaires Europeennes. This book was released on 2012 with total page 132 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cet ouvrage qui porte sur l'evaluation economique de l'amelioration de l'approvisionnement en eau potable au Cameroun s'inscrit dans le cadre d'une conjoncture qui favorise la contribution des beneficiaires a la gestion des infrastructures sociales. Avec la privatisation du secteur de l'eau, les decideurs publics ne peuvent se passer de telles evaluations pour choisir une politique de prix qui tienne compte de la maximisation des benefices economiques et sociaux. Son objectif principal est de montrer comment estimer la valeur economique de l'amelioration de l'approvisionnement en eau potable. L'application porte sur la ville de Soa. Ce choix s'explique tout simplement par le fait que l'acces a l'eau potable dans cette ville demeure un probleme urgent que les populations souhaiteraient resoudre en priorite.
Download or read book Demande en eau potable written by Mourad Kertous and published by . This book was released on 2012 with total page 411 pages. Available in PDF, EPUB and Kindle. Book excerpt: La majorité des travaux sur la demande en eau domestique traitent soit des déterminants de la demande en eau, soit du consentement à payer pour améliorer la qualité du service en eau potable. Dans ce travail, nous proposons une analyse approfondie de la demande en eau potable en Algérie. Après avoir exposé dans un premier chapitre la situation de l'eau en Algérie, et dans le cas de Wilaya de Bejaia, nous avons fait une revue de la littérature pour déterminer les points communs et les contraintes qui pèsent sur ce type de travaux. Dans le troisième chapitre, nous avons estimé la fonction de demande en eau potable sur trois bases de données (données agrégées, sonnées relatives aux consommations réelles de 27363 abonnés, observés sur 17 trimestres et sur un échantillon de 172 abonnés observés sur une période de 45 trimestres) . Ces estimations révèlent que les abonnés de la wilaya de Bejaia sont peu sensibles aux variations des prix (des élasticités-prix comprises entre - 0,14 et - 0,67). Ces estimations montrent également que les résultats des élasticités-prix sont en partie la conséquence de la période d'estimation et de la nature des données utilisées.Pour compléter notre analyse, nous avons, dans le chapitre quatre, analysé l'incidence d'une augmentation des prix et d'un durcissement de la politique de restriction sur le bien-être des ménages. Cette analyse nous renseigne qu'une heure supplémentaire de restriction est équivalente à une augmentation des prix de 10 %/ Nous avons également analysé les facteurs responsables de la réticence des abonnés à payer leurs factures/. Cette analyse révèle qu'une partie des retards s'explique par des facteurs économiques (tels que les revenus et les prix...) mais l'autre partie semble s'expliquer par un mécontentement des abonnés vis à vis de la qualité du service en eau potable. Pour confirmer ce résultat, nous avons estimé, dans une dernière section, le consentement à payer des abonnés. Cette estimation révèle que 99,4% de notre échantillon est prêt à payer pour améliorer la qualité du service. Le CAP estimé nous renseigne que les abonnés locaux sont prêts à payer 10,57 DA/m3 supplémentaires pour bénéficier d'un meilleur service en eau potable.
Download or read book Sustainable Development in Africa written by Walter Leal Filho and published by Springer Nature. This book was released on 2021-07-09 with total page 729 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book serves the purpose of documenting and promoting African experiences on sustainable development, which encompasses both, formal and non-formal education. Sustainable development is very important to Africa, but there is a paucity of publication which documents and promotes experiences from African countries. Due to their complexity, the interrelations between social, economic and political factors related to sustainable development, especially at universities, need to be better understood. There is also a real need to showcase successful examples of how African institutions are handling their sustainability challenges. It is against this background that this book has been produced. It is a truly interdisciplinary publication, useful to scholars, social movements, practitioners and members of governmental agencies and private companies, undertaking research and/or executing projects focusing on sustainability from across Africa. As African nations strive to pursue the UN Sustainable Development Goals, it is imperative to cater for the information needs seen across the continent and foster the dissemination of experiences and case studies, which may support both, on-going and future efforts. The scope of the book is deliberately kept wide, and we are looking for contributions across the spectrum of sustainable development from business and economics, to arts and fashion, administration, environment, languages and media studies.
Download or read book Ecology and Natural Resource Development in the Western Highlands of Cameroon Issues in Natural Resource Management written by Cornelius Mbifung Lambi and published by African Books Collective. This book was released on 2010 with total page 220 pages. Available in PDF, EPUB and Kindle. Book excerpt: The densely populated Bamenda Highlands of Cameroon remains one of the regions with the greatest land degradation problems in the country. Factors responsible for this include climate change, the hilly nature or topographic layout of the land, and human interference through overgrazing, destructive agricultural practices and the impact of deforestation. This detailed study of resource management and its ecological challenges in the Bamenda Highlands, stresses an important link between falling food output and soil deterioration. While most areas in this predominantly agricultural region enjoy food abundance, the inhabitants of high-density infertile, rugged mountainous areas are forced to resort to double cropping and intensified land exploitation that leave little room for soil regeneration. The population problem in relation to land degradation is infinitely more complicated than the region's sheer ability to produce enough food supply. The authors make a strong case for a delicate balance between human agency and environmental protection in this highly populated and physically challenging region where land is a precious resource and land conflicts are common.

Download or read book Understanding and Managing Urban Water in Transition written by Quentin Grafton and published by Springer. This book was released on 2015-05-06 with total page 640 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book examines changes and transitions in the way water is managed in urban environments. This book originated from a joint French-Australian initiative on water and land management held in Montpellier, France. The book delivers practical insights into urban water management. It links scientific insights of researchers with the practical experiences of urban water practitioners to understand and respond to key trends in how urban water is supplied, treated and consumed. The 51 contributors to the volume provide a range of insights, case studies, summaries and analyses of urban water and from a global perspective. The first section on water supply and sanitation includes case studies from Zimbabwe, France and South Africa, among others. Water demand and water economics are addressed in the second section of the book, with chapters on long-term water demand forecasting, the social determinants of water consumption in Australian cities, a study of water quality and consumption in France, governance and regulation of the urban water sector and more. The third section explores water governance and integrated management, with chapters on water management in Quebec, in the Rotterdam-Rijnmond urban area, in Singapore and in Australia. The final section offers perspectives on challenges and future uncertainties for urban water systems in transition. Collectively, the diverse insights provide an important step forward in response to the challenges of sustainably delivering water safely, efficiently and equitably.

Download or read book International Human Rights Law in Africa written by Frans Viljoen and published by OUP Oxford. This book was released on 2012-03-29 with total page 661 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides a comprehensive and analytical overview of human rights law in Africa. It examines the institutions, norms, and processes for human rights realization provided for under the United Nations system, the African Union, and sub-regional economic communitites in Africa, and explores their relationship with the national legal systems of African states. Since the establishment of the African Union in 2001, there has been a proliferation of regional institutions that are relevant to human rights in Africa. These include the Pan African Parliament, the Peace and Security Council, the Economic, Social and Cultural Council and the African Peer Review Mechanism of the New Partnership for Africa's Development. This book discusses the links between these institutions. It further examines the case law stemming from Africa' most important human rights instrument, the African Charter on Human and Peoples Rights, which entered into force on 21 October 1986. This new edition contains a new chapter on the African Children's Rights Committee as well as full coverage of new developments and instruments, such as the Convention on the Rights of Persons with Disabilities, the Convention on Enforced Disappearances, and the African Charter on Democracy, Elections and Governance. Three cross-cutting themes are explored throughout the book: national implementation and enforcement of international human rights law; legal and other forms of integration; and the role of human rights in the eradication of poverty. The book also provides an introduction to the relevant human rights concepts.
Download or read book Governing Africa s Forests in a Globalized World written by Laura Anne German and published by Routledge. This book was released on 2009-12-01 with total page 435 pages. 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.
