Download or read book Taming the Anarchy written by Tushaar Shah and published by Routledge. This book was released on 2010-09-30 with total page 321 pages. Available in PDF, EPUB and Kindle. Book excerpt: In 1947, British India-the part of South Asia that is today's India, Pakistan, and Bangladesh-emerged from the colonial era with the world's largest centrally managed canal irrigation infrastructure. However, as vividly illustrated by Tushaar Shah, the orderly irrigation economy that saved millions of rural poor from droughts and famines is now a vast atomistic system of widely dispersed tube-wells that are drawing groundwater without permits or hindrances. Taming the Anarchy is about the development of this chaos and the prospects to bring it under control. It is about both the massive benefit that the irrigation economy has created and the ill-fare it threatens through depleted aquifers and pollution. Tushaar Shah brings exceptional insight into a socio-ecological phenomenon that has befuddled scientists and policymakers alike. In systematic fashion, he investigates the forces behind the transformation of South Asian irrigation and considers its social, economic, and ecological impacts. He considers what is unique to South Asia and what is in common with other developing regions. He argues that, without effective governance, the resulting groundwater stress threatens the sustenance of the agrarian system and therefore the well being of the nearly one and a half billion people who live in South Asia. Yet, finding solutions is a formidable challenge. The way forward in the short run, Shah suggests, lies in indirect, adaptive strategies that change the conduct of water users. From antiquity until the 1960‘s, agricultural water management in South Asia was predominantly the affair of village communities and/or the state. Today, the region depends on irrigation from some 25 million individually owned groundwater wells. Tushaar Shah provides a fascinating economic, political, and cultural history of the development and use of technology that is also a history of a society in transition. His book provides powerful ideas and lessons for researchers, historians, and policy
Download or read book Indicators of Environmental Quality written by William A. Thomas and published by Springer Science & Business Media. This book was released on 2013-03-09 with total page 253 pages. Available in PDF, EPUB and Kindle. Book excerpt: Researchers and agencies collect reams of objective data and authors publish volumes of subjective prose in attempts to explain what is meant by environmental quality. Still, we have no universally recognized methods for combining our quantitative measures with our qualitative concepts of environ ment. Not all of our environmental goals should be reduced to mere numbers, but many of them can be; and without these quantitative terms, we have no way of defining our present position nor of selecting positions we wish to attain on any logically established scale of environmen tal values. Stated simply, in our zeal to measure our environment we often forget that masses of numbers describing a system are insufficient to understand it or to be used in selecting goals and priorities for expending our economic and human resources. Attempts at quantitatively describing environmental quality, rather than merely measuring different environmental variables, are relatively recent. This condensing of data into the optimum number of terms with maximum information content is a truly interdisciplinary challenge. When Oak Ridge National Laboratory initiated its Environmental Program in early 1970 under a grant from the National Science Foundation, the usefulness of environmental indicators in assessing the effects of technology was included as one of the initial areas for investigation. James L. Liverman, through his encouragement and firm belief that these indicators are indispensable if we are to resolve our complex environmental problems, deserves much of the credit for the publication of this book.

Download or read book L irrigation avec des eaux us es et la sant written by Pay Drechsel and published by PUQ. This book was released on 2011-11-25T00:00:00-05:00 with total page 449 pages. Available in PDF, EPUB and Kindle. Book excerpt: Dans la plupart des pays en développement, les systèmes de traitement des eaux usées sont très peu étendus ou sont peu efficaces, ce qui engendre une pollution de l’eau à vaste échelle et l’utilisation d’eau de mauvaise qualité pour l’irrigation des cultures, notamment à proximité des centres urbains. Cela pose de grands risques pour la santé publique, en particulier lorsque la production est consommée crue.L’irrigation avec des eaux usées et la santé aborde ce sérieux problème d’un point de vue pratique et réaliste, en traitant des enjeux de l’évaluation des risques pour la santé et de leur atténuation dans le contexte des pays en développement. Le livre est donc un complément utile d’autres ouvrages consacrés au thème des eaux usées qui mettent l’accent sur les options de traitement haut de gamme et sur l’utilisation des eaux usées.Ce livre fait avancer le débat en couvrant également la réalité, répandue, de l’utilisation des eaux usées non traitées, des eaux grises et des excrétas. Il présente des méthodes d’avant-garde d’évaluation quantitative des risques de même que des solutions peu coûteuses pour la réduction des risques pour la santé, depuis le traitement jusqu’aux mesures adoptées sur la ferme et hors de la ferme, qui vont dans le sens de l’approche à barrières multiples préconisée dans les lignes directrices relatives à l’utilisation sans risque des eaux usées en agriculture publiées par l’Organisation mondiale de la santé en 2006. Les 38 auteurs et coauteurs sont des experts internationaux clés dans le domaine de l’irrigation au moyen d’eaux usées, à savoir des agronomes, ingénieurs, spécialistes des sciences sociales et chercheurs en santé publique d’Afrique, d’Asie, d’Europe, d’Amérique du Nord et d’Australie. Les chapitres présentent des expériences vécues un peu partout dans les pays en développement, notamment des études de cas portant sur l’Afrique subsaharienne, l’Asie, le Mexique et le Moyen-Orient. Le livre traite également d’options en matière de récupération des ressources et de gouvernance des eaux usées en établissant ainsi un lien clair entre agriculture, santé et assainissement qui est souvent le chaînon manquant des débats actuels sur la question de faire des eaux usées un atout.

Download or read book De l eau agricole l eau environnementale written by Chantal Aspe and published by Editions Quae. This book was released on 2012-03-07 with total page 386 pages. Available in PDF, EPUB and Kindle. Book excerpt: « Les choses de la nature n’ont de statut que celui que les sociétés leur accordent ». C’est à partir de cette hypothèse que les auteurs de cet ouvrage analysent le changement actuel du statut de l’eau dans les pays du Bassin méditerranéen. Peu à peu, l’« eau agricole » laisse place à l’« eau environnementale ». Aujourd’hui, les ouvrages hydrauliques à vocation agricole sont conçus pour rendre des services environnementaux comme la protection de la biodiversité et du paysage, l’arrosage des jardins, la gestion des inondations et du débit d’étiage des rivières ou les recharges de nappe phréatique. Déjà, en 2000, une directive cadre européenne sur l’eau témoignait de ces mutations et les suscitait à travers la nécessité de faire des économies d’eau. Mais ces transformations ne se font pas au même rythme au nord ou au sud du Bassin méditerranéen. D’un pays à l’autre, les formes de résistance et d’adaptation sont très diverses. Les auteurs donnent de ces nouveaux enjeux de partage de l’eau un éclairage multiple, international et pluridisciplinaire. Sociologues, économistes, géographes, spécialistes de l’écologie ou de l’hydrobiologie, ils présentent des expériences issues de leur pays d’origine, la France, l’Espagne, le Maroc, l’Algérie, la Tunisie et l’Italie. Au cœur de l’actualité économique et sociale contemporaine, cet ouvrage s’adresse aussi bien aux chercheurs, enseignants et étudiants qui s’intéressent à la gestion de l’eau en Méditerranée qu’aux décideurs et professionnels en charge de la recomposition de ce secteur.
