Download or read book Nitrate Contamination written by Istvan Bogardi and published by Springer Science & Business Media. This book was released on 2013-06-29 with total page 438 pages. Available in PDF, EPUB and Kindle. Book excerpt: The nitrate content of drinking water is rising at an alarming rate in several regions of NATO countries and elsewhere in the world. The increase is due to lack of proper sewage treatment, and primarily to excess fertilizer application. Also, eutrophication in several coastal areas is triggered by high nitrate concentrations. The main purpose of this book is to integrate scientific knowledge related to exposure assessment, health consequences and control of nitrate contamination in water. The motivation is related to the magnitude, the possible adverse health effects, and the high cost of control ling nitrate contamination. Future research tasks are defined by an interaction among hydro logists, toxicologists and environmental engineers in an integrated framework for nitrate risk management. The target readership of this book is a mix of university colleagues, practitioners from both the private and public sectors and advanced graduate students working with the hydrological, health science or environmental engineering aspects of nitrate contamination. The main conclusions include: 1. For risk assessment purposes, knowledge and sufficiently accurate models are available to predict nitrate load and its fate in water under changes in land use. 2. Once agricultural exposure controls are implemented, the response times in ground water may be so long as to make controls unrealistic. 3. It is still unknown whether agricultural best management practice is a compromise between nitrate risk reduction and agricultural revenue. 4. The current drinking water guidelines of 10 mg/L NOrN need not be changed.
Download or read book Intensive Use of Groundwater written by M. Ramon Llamas and published by CRC Press. This book was released on 2002-01-01 with total page 498 pages. Available in PDF, EPUB and Kindle. Book excerpt: This text is written by a number of authors from different countries and disciplines, affording the reader an invaluable and unbiased perspective on the subject of intensive groundwater development. Based on information gathered from the experience of many countries over the last decades, the text aims to present a clear discussion on the conventional hydrogeological aspects of intensive groundwater use, along with the ecological, legal, institutional, economic and social challenges. Divided into two main sections, the first group of authors put forward the positive and negative aspects of intensive groundwater use, whilst a second group provide an overview of the situation specific countries face as a consequence of this phenomenon. Fully revised and up-to-date, Groundwater Intensive Use makes a significant number of discoveries in a subject area that is topical in today's climate.
Download or read book Agriculture in Semi Arid Environments written by A.E. Hall and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 357 pages. Available in PDF, EPUB and Kindle. Book excerpt: The semi-arid zones of the world are fragile ecosystems which are being sub stantially modified by the activities of mankind. Increasing human populations have resulted in greater demands on semi-arid zones for providing human susten ance and the possibility that this may enhance desertification is a grave concern. These zones are harsh habitats for humans. The famines that resulted from drought during the late 1960's and the 1970's in the African Sahel illustrated the unreliability of present agricultural systems in this zone. Large fluctuations in ag ricultural production have occurred in semi-arid zones of Australia, North Ameri ca, and the Soviet Union due to periodic droughts, even though considerable ag ricultural technology has been devoted to agricultural development in these zones. The challenge to mankind is to manage these different semi-arid zones so that pro ductivity is increased and stabilized, and environmental deterioration is decreased. Irrigation can be used to increase and stabilize agricultural production in semi-arid zones as discussed in Volume 5 of this series, Arid Zone Irrigation. The present volume, Agriculture in Semi-Arid Environments, focuses on dryland farming in semi-arid zones, and is relevant to the large areas of the world where rainfall is limiting and where water is not available for irrigation. This volume is designed to assist agricultural development in these areas and consists of reviews and analyses of available information by scientists working in Africa, Australia, and at the U ni versity of California.

Download or read book The Political Economy of Water Pricing Reforms written by Ariel Dinar and published by Elsevier. This book was released on 2000 with total page 200 pages. Available in PDF, EPUB and Kindle. Book excerpt: Lately our world has witnessed massive changes and reforms in various sectors in many countries, developing and developed alike. Institutional and pricing reforms in the water sector are also part of that recent trend. They are led by the recognition of a need to respond to increased scarcity and deteriorated quality. Is the water sector different than other sectors, as some claim? Should reforms in the water sector be designed and implemented differently than reforms of a similar type, in other sectors? The Political Economy of Water Pricing Reforms answers these questions by providing various analytical frameworks that allow comparison across various conditions, and by actually comparing reform processes under various conditions in different countries. This book demonstrates the common threads that characterize pricing reforms in the water sector by analyzing various aspects of the reforms in the irrigation and urban subsectors of 10 countries. Cases from Morocco, Senegal, Honduras, Belgium, Australia, Brazil, Mexico, Pakistan, Yemen, and the United States illustrate the difficulties of designing and implementing "optimal" pricing reforms and explain how reform outcomes fall short of the original objective. "This book should be on the must reading list for anyone interested in water pricing and how to reform water rights systems to achieve increased economic efficiency as well as a legitimate and equitable system of property rights."

Download or read book Trust in Numbers written by Theodore M. Porter and published by Princeton University Press. This book was released on 2020-08-18 with total page 336 pages. Available in PDF, EPUB and Kindle. Book excerpt: A foundational work on historical and social studies of quantification What accounts for the prestige of quantitative methods? The usual answer is that quantification is desirable in social investigation as a result of its successes in science. Trust in Numbers questions whether such success in the study of stars, molecules, or cells should be an attractive model for research on human societies, and examines why the natural sciences are highly quantitative in the first place. Theodore Porter argues that a better understanding of the attractions of quantification in business, government, and social research brings a fresh perspective to its role in psychology, physics, and medicine. Quantitative rigor is not inherent in science but arises from political and social pressures, and objectivity derives its impetus from cultural contexts. In a new preface, the author sheds light on the current infatuation with quantitative methods, particularly at the intersection of science and bureaucracy.
