Sustainable Water Solutions
This book is the result of a long-term co-operative research and professional development programme between the Instituto de Investigaciones Electricas (IIE), Mexico, and the University of Salford, UK. It provides the design basis for the fabrication of small and large scale commercial absorption heat pump systems, and includes a comprehensive treatment of the economics of heat pump systems. It charts the development of heat pump technology from theoretical principles to the operation of practical systems for the purification of water, both for human consumption and a wide variety of industrial purposes.
The fine estuary which penetrates the American coast, between the fortieth and forty-first degrees of latitude, is formed by the confluence of the Hudson, the Hackensack, the Passaic, the Raritan, and a multitude of smaller streams; all of which pour their tribute into the ocean, within the space named. The islands of Nassau and Staten are happily placed to exclude the tempests of the open sea, while the deep and broad arms of the latter offer every desirable facility for foreign trade and internal intercourse. To this fortunate disposition of land and water, with a temperate climate, a central position, and an immense interior, that is now penetrated, in every direction, either by artificial or by natural streams, the city of New-York is indebted for its extraordinary prosperity. Though not wanting in beauty, there are many bays that surpass this in the charms of scenery; but it may be questioned if the world possesses another site that unites so many natural advantages for the growth and support of a widely extended commerce. As if never wearied with her kindness, Nature has placed the island of Manhattan at the precise point that is most desirable for the position of a town. Millions might inhabit the spot, and yet a ship should load near every door; and while the surface of the land just possesses the inequalities that are required for health and cleanliness, its bosom is filled with the material most needed in construction.
Burgeoning population and climate change are among the most critical challenges facing the 21st century. Both have critical implications for groundwater resources, especially in many developing countries where resources are already under pressure. Due to low rainfall and high evaporation in parts of the Middle East and North Africa, groundwater is not being renewed, andÃ¿groundwater laid down up to 10,000 years ago is literally being mined for irrigation, often very inefficiently. Over recent decades, groundwater levels have fallen dramatically in key grain-growing regions like the American Great Plains and the North China Plain. As the population grows and emerging economies like China and India demand more food, especially water intensive meat products, agricultural demand for water is set to increase. The rapid shift of population from the countryside to the cities is also adding to this pressure; most old wells in Beijing are now dry. Pollution from industry, agriculture and shanty towns is destroying many groundwater resources; some could take 50 years to clean up even with strict and immediate controls.
This volume looks at the technical, socio-economic and political problems being faced, and at the developments in groundwater science and management that may help create a sustainable future for our planet.
'How to Clean a Hippopotamus', a book about animal symbiosis, offers readers a close-up, step-by-step view of nature's fascinating partnerships. Find out why a mongoose comes running when a warthog lies down, how a crab and an iguana help each other out, why ravens follow wolves, and more. Witness the ingenious lifestyles of some of the world's most unusual animal partners in this book of curious biology, a symbiotic collaboration by Steve Jenkins and Robin Page. AGES: 6-9 AUTHOR: Steve Jenkins and Robin Page share a burrow in Boulder, Colorado, where they work and forage together, occasionally picking lint off each other's sweaters. They enjoy a happy host/parasite relationship with their son Jamie. Their two other nestlings have fledged. Visit www.stevejenkinsbooks.com for more information about the authors and their books. REVIEWS: "Another outstanding offering from this extraordinarily talented couple." -School Library Journal, starred review Colour
