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'.
Manual water supply pumps agricultural equipment - irrigation and energy crisis; general principles of pumping water using electric power, wind power, solar energy, hydroelectric power, biomass; economic evaluation of various systems; labour demand. Diagrams, illustrations, references, tables.
Water played an important part of ancient Roman life, from providing necessary drinking water, supplying bath complexes, to flowing in large-scale public fountains. The Roman culture of water was seen throughout the Roman Empire, although it was certainly not monolithic and it could come in a variety of scales and forms, based on climatic and social conditions of different areas. This article seeks to define ‘water culture’ in Roman society by examining literary, epigraphic, and archaeological evidence, while understanding modern trends in scholarship related to the study of Roman water. The culture of water can be demonstrated through expressions of power, aesthetics, and spectacle. Further there was a shared experience of water in the empire that could be expressed through religion, landscape, and water’s role in cultures of consumption and pleasure.
Freshwater scarcity is a critical challenge, with social, economic, political and environmental consequences. Water crises in Australia have already led to severe restrictions being applied in cities, drought ravaging farmlands, and the near-terminal decline of some rivers and wetlands. A Water Story provides an account of Australian water management practices, set against important historical precedents and the contemporary experience of other countries. It describes the nature and distribution of the country's natural water resources, management of these resources by Indigenous Australians, the development of urban water supply, and support for pastoral activities and agricultural irrigation, with the aid of case studies and anecdotes. This is followed by discussion of the environmental consequences and current challenges of water management, including food supply, energy and climate change, along with options for ensuring sustainable, adequate high-quality water supplies for a growing population. A Water Story is an important resource for water professionals and those with an interest in water and the environment and related issues, as well as students and the wider community.
The ancient Sahara has often been treated as a periphery or barrier, but this agenda-setting book – the final volume of the Trans-Saharan Archaeology Series – demonstrates that it was teeming with technological innovations, knowledge transfer, and trade from long before the Islamic period. In each chapter, expert authors present important syntheses, and new evidence for technologies from oasis farming and irrigation, animal husbandry and textile weaving, to pottery, glass and metal making by groups inhabiting the Sahara and contiguous zones. Scientific analysis is brought together with anthropology and archaeology. The resultant picture of transformations in technologies between the third millennium BC and the second millennium AD is rich and detailed, including analysis of the relationship between the different materials and techniques discussed, and demonstrating the significance of the Sahara both in its own right and in telling the stories of neighbouring regions.
The excavation of the earliest Roman port and fishery known establishes Cosa as the center for the flourishing commercial activities of the powerful Sestius family and extends the international trading picture of the Romans back to at least the early second century B.C. Originally published in 1987. The Princeton Legacy Library uses the latest print-on-demand technology to again make available previously out-of-print books from the distinguished backlist of Princeton University Press. These editions preserve the original texts of these important books while presenting them in durable paperback and hardcover editions. The goal of the Princeton Legacy Library is to vastly increase access to the rich scholarly heritage found in the thousands of books published by Princeton University Press since its founding in 1905.
This is a study of the water-raising wheels of western Syria from the aspects of sources, terminology, typology, origin, history, technology and architecture, and gives a survey of these installations, discussing their present state of conservation. By making use of historical, architectural and iconographical material, the study shows that Syrian water-wheels constitutes a particular type of water-architecture, which successfully combines the functional with the aesthetic and displays sophisticated forms of construction. These devices are visually impressive, present a variety of shapes and are of great historical, environmental and iconographical importance, being of extraordinarily accurate and detailed design. An attempt is made to present evidence of their ancient origin, and to gain an understanding of how their design evolved over time, the reasons for their significance and uniqueness, and for their great concentration in Syria.
