Book excerpt: Efficient and effective irrigation of the land can have a dramatic effect on the agricultural output and the economic well-being of a community. At the heart of effective irrigation lies the problem of lifting or pumping water, and this handbook surveys the water-lifting technologies that are available and appropriate for smallholdings. It is a detailed and practical review of the options, especially for irrigation but also for other purposes, and the costs and general suitability of the different technologies are examined with the aim of enabling farmers and policymakers to make informed choices. This is an updated and expanded new edition of a book formerly called 'Water Pumping Devices'.

Available in PDF, EPUB and Kindle. Book excerpt: Water is fundamental to human life, and the ways in which a society uses it can tell us a great deal about a people. The ancient Greeks and Romans had at their disposal several mechanical water-lifting devices. The water-screw, the force pump, the compartmented wheel, and the bucket-chain were developed by scientists associated with the great school at Alexandria. Application of these devices was sporadic in the Hellenistic world, but they, and the later saqiya gear, were used in a wide range of rural and urban settings in many parts of the Roman Empire. Professor Oleson has prepared a definitive study of mechanical water-lifting devices in the Greek and Roman world. He systematically and thoroughly examines the literary, papyrological, and archaeological evidence for the devices and considers the design, materials, settings, costs, effectiveness, and durability of the many adaptations of the small basic repertoire of models. The literary and papyrological materials range from Deuteronomy to papyri of the seventh century AD, and the archaeological sites discussed range from Babylon to Wales. An extensive collection of illustrations complements the literary, papyrological, and archaeological evidence for this remarkable ancient technology.

Download or read book Himalayan Glaciers written by National Research Council and published by National Academies Press. This book was released on 2012-11-29 with total page 218 pages. Available in PDF, EPUB and Kindle. Book excerpt: Scientific evidence shows that most glaciers in South Asia's Hindu Kush Himalayan region are retreating, but the consequences for the region's water supply are unclear, this report finds. The Hindu Kush Himalayan region is the location of several of Asia's great river systems, which provide water for drinking, irrigation, and other uses for about 1.5 billion people. Recent studies show that at lower elevations, glacial retreat is unlikely to cause significant changes in water availability over the next several decades, but other factors, including groundwater depletion and increasing human water use, could have a greater impact. Higher elevation areas could experience altered water flow in some river basins if current rates of glacial retreat continue, but shifts in the location, intensity, and variability of rain and snow due to climate change will likely have a greater impact on regional water supplies. Himalayan Glaciers: Climate Change, Water Resources, and Water Security makes recommendations and sets guidelines for the future of climate change and water security in the Himalayan Region. This report emphasizes that social changes, such as changing patterns of water use and water management decisions, are likely to have at least as much of an impact on water demand as environmental factors do on water supply. Water scarcity will likely affect the rural and urban poor most severely, as these groups have the least capacity to move to new locations as needed. It is predicted that the region will become increasingly urbanized as cities expand to absorb migrants in search of economic opportunities. As living standards and populations rise, water use will likely increase-for example, as more people have diets rich in meat, more water will be needed for agricultural use. The effects of future climate change could further exacerbate water stress. Himalayan Glaciers: Climate Change, Water Resources, and Water Security explains that changes in the availability of water resources could play an increasing role in political tensions, especially if existing water management institutions do not better account for the social, economic, and ecological complexities of the region. To effectively respond to the effects of climate change, water management systems will need to take into account the social, economic, and ecological complexities of the region. This means it will be important to expand research and monitoring programs to gather more detailed, consistent, and accurate data on demographics, water supply, demand, and scarcity.
Download or read book Water and the Environmental History of Modern India written by Velayutham Saravanan and published by Bloomsbury Publishing. This book was released on 2020-01-23 with total page 264 pages. Available in PDF, EPUB and Kindle. Book excerpt: This important new study investigates the competing demand for water in the Bhavani and Noyyal River basins of south India from the early 19th century to the early 21st century from a historical perspective. In doing so, the book addresses several important questions: * Did policy-makers visualise the future demand while diverting water from distant places or other basins? * Was efficient use ensured when the water was diverted or was it diverted in a manner that resulted in pollution and serious damage to the entire river basin? * Were natural flows taken care of in order to preserve the ecology and environment? * What were the factors that aggravated the competing demand for water and what were the consequences for the future? In the context of the current discourse on the competing demands for water, this book takes the debate forward, expanding the horizon of environmental history in the process. Until now, agriculture, industry and domestic water supply and their consequences for ecology, the environment and livelihoods have been given scant attention. Velayutham Saravanan's comprehensive account of both the colonial and post-colonial periods corrects this shortcoming in the field's literature and gives a holistic understanding of the problem and its full historical roots.

Available in PDF, EPUB and Kindle. Book excerpt: Man’s control over the elements of land and water for the purposes of agriculture was fundamental to the development of civilisations in the past, and remains so today. This volume deals with the processes of irrigation, and land drainage and reclamation, and illustrates the variety of technological and engineering solutions in a wide chronological and geographical perspective. The sophistication of many pre-modern systems is clear, as is the impact of modern technologies. Important points that emerge are that there was no steady or linear progression in techniques across time - instances of the transfer of ideas are balanced by cases of independent development - and that the correlations between irrigation systems and social structures demand more complex explanations than often proposed.

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 322 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 Environmental History of Water written by Petri S. Juuti and published by IWA Publishing. This book was released on 2007-02-01 with total page 642 pages. Available in PDF, EPUB and Kindle. Book excerpt: The World Water Development Report 2003 pointed out the extensive problem that: 'Sadly, the tragedy of the water crisis is not simply a result of lack of water but is, essentially, one of poor water governance.' Cross-sectional and historical intra-national and international comparisons have been recognized as a valuable method of study in different sectors of human life, including technologies and governance. Environmental History of Water fills this gap, with its main focus being on water and sanitation services and their evolution. Altogether 34 authors have written 30 chapters for this multidisciplinary book which divides into four chronological parts, from ancient cultures to the challenges of the 21st century, each with its introduction and conclusions written by the editors. The authors represent such disciplines as history of technology, history of public health, public policy, development studies, sociology, engineering and management sciences. This book emphasizes that the history of water and sanitation services is strongly linked to current water management and policy issues, as well as future implications. Geographically the book consists of local cases from all inhabited continents. The key penetrating themes of the book include especially population growth, health, water consumption, technological choices and governance. There is great need for general, long-term analysis at the global level. Lessons learned from earlier societies help us to understand the present crisis and challenges. This new book, Environmental History of Water, provides this analysis by studying these lessons.
