Die Anregung, dies Buch zu schreihen, trat an dem Abend an mich heran, an dem ich zum ersten Male versuchte, die biologischen Ergebnisse der "Meteor"-Expedition in groBen Umrissen einem wissenschaftlichen Kreise vorzutragen. Die Erinnerungen jahrelanger Seefahrt, auf der langsam eine groBe Gesamtanschauung vom Leben des Weltmeers in mir herangewachsen war, verbanden sich in dieser Stunde mit Erinnerungen weit zuriickliegender Jahre: Ich dachte an die Zeit, da ich einen der groBten deutschen Meister versUind lidher Wissenschaft, Alexander von Humboldt, zum ersten Male las. Ich habe vielleicht nie wieder so stark wie damals reine Wissenschaft als in das Leben eingreifende Macht ernpfunden. Spater, inmitten der Oberfiille von Wissenschaft aller Art, ist mir dies Gefiihl oft verlorengegangen. Das Wesentliche, das wirklich Wissenswerte wird heute von so viel weniger Wichtigern, selbst Wertlosem iiberwuchert, dill. man leicht den Blick fiir die grofien Ziige des Ganzen verliert. Die Wissenschaft wachst in vielen ihrer Teile wie ein unbe schnittener Baurn, an dem die fruchtbaren Zweige unter dem Wuchem der unfruchtbaren leiden. Ich habe mich daher viel urn die Frage bemiiht: Was ist wissenswert? Und warum ist etwas wissenswert? - Gewifi vieles deswegen, weil es Nutzen bringt. Aber den Wert der Wissenschaft an der praktischen Verwertharkeit ihrer Er gebnisse messen oder gar die "angewandte" Wissenschaft hoher als die "reine," zweckunbewuBte bewerten, das hieBe, v Apfel und Trauben nach ihrem Nahrwert sehatzen wollen."

Calcium and magnesium are abundant in groundwater, but the role of groundwater as the essential source of these important nutrients is very often neglected. Hydrogeochemical studies are focused mainly on distribution and behaviour of constituents that cause deterioration of water quality, such as: nitrate, nitrite or iron, manganese. Therefore, most recent books and papers concentrate mainly on these water components and only a small number of papers describe results of groundwater studies on valuable water components as calcium or magnesium. Calcium and magnesium are of great importance to human health and inadequate intake of either nutrient can impair health. The main objective of this IAH Selected Papers book is to present the results of the studies on calcium and magnesium in groundwater as well as their importance for human health.
The chapters in this book are written by hydrogeologists and hydrochemists as well as medical doctors and include: methods of investigation of calcium and magnesium in groundwaters, distribution and behaviour of calcium and magnesium in different aquifers, calcium and magnesium in bottled mineral and spring waters, significance of calcium and magnesium in waters for human health.

The Waters of the Nile - Hydropolitics and the Jonglei Canal, 1900-88 (Paperback, New edition): Robert O. Collins The Waters of the Nile - Hydropolitics and the Jonglei Canal, 1900-88 (Paperback, New edition)

This is a history of the hydropolitics of the Nile Valley from 1900 to 1988. Attempts to develop the Nile and control its waters are of vital significance to the future of the inhabitants of Egypt, the Sudan, Ethiopia, and East Africa. Acute drought and heavy flooding in the Nile Basin have brought disaster in the past, and the history of the area is the story of human effort to control the precious waters of the river. Written by Robert O. Collins, distinguished authority in the field, this highly interdisciplinary study will appeal to those interested in the environment, politics, third world development, anthropology, zoology, and economic history. Robert O. Collins, University of California, Santa Barbara, was the author Africa: A Short History and Darfur: The Long Road to Disaster (with J. Millard Burr), as well as many other titles available from Markus Wiener.
