This book was released on 2013-04-17 with total page 142 pages. Available in PDF, EPUB and Kindle. Book excerpt: A shortage of water exists, not only in the arid regions of the world, but even in some moderately humid climates. This situation is a consequence of water require ments for agriculture and industry in amounts greater than the natural surplus. Even in Europe there is increased anxiety over the state of water reserves, and shortages are forecast for the near future if industry continues to expand. During the past 50 years in the United States, water use has increased about twice as fast as the rate of population growth, and shortages have already appeared in some places. The need to conserve declining water resources which has become apparent over the last few decades has led several investigators to conclude that plants with a high rate of transpiration endanger water resources, and the growth of such plants must not be encouraged. Some think that trees withdraw more water from the soil than other plant species and evaporate it excessively through the stomata of leaves. THORNTHWAITE and HARE (1955) explained transpiration on the same thermo dynamic basis as evaporation, and calculated its rate, using DALTON'S law or modifications thereof. In spite ofthe many past and present investigations into the problems of transpiration, the biological aspects of this essential process is still poorly understood.

Download or read book Tribes and Territories in Transition written by Eveline J. van der Steen and published by Peeters Publishers. This book was released on 2004 with total page 354 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume deals with the transition from the Late Bronze to the Early Iron Age in the central East Jordan Valley, the period of the fall of the Egyptian New Kingdom, and of the birth of a new era, in which small kingdoms such as Ammon, Moab and Israel were born. A broad spectrum of sources is being reviewed: written evidence, excavations and surveys, and ethnographic sources from the 19th century and later. New archaeological evidence is being presented, including a report on the excavations of Tell el-Hammeh on the Zerqa. This evidence, written, material and ethnographical, is incorporated in a new model for the LB-IA transition in the region: a model that explains the events of this turbulent period as the precipitation of a tribal society, where the interactions of tribes and territories determined the political lay-out and shaped the kingdoms of the Iron Age.

This book was released on 2019-12-05 with total page 88 pages. Available in PDF, EPUB and Kindle. Book excerpt: Water – drinkable, usable water – is likely to be one of the most limiting resources in the future, given the growing global population, the high water demand of most agricultural production systems, and the confounding effects of climate change. We need to manage water wisely – efficiently, cost-effectively and equitably – if we are to avoid the calamity of a lack of usable water supply. Forested watersheds provide an estimated 75 percent of the world’s accessible freshwater resources, on which more than half the Earth’s people depend for domestic, agricultural, industrial and environmental purposes. Forests therefore, are vital natural infrastructure, and their management can provide “nature-based solutions” for a range of water-related societal challenges. This edition of Unasylva explores that potential.
