In the heart of Africa, a unique lake attracts the attention of scientists since the beginning of the 20th century. At the foot of the Virunga volcano chain, Lake Kivu harbors a vast amount of dissolved carbon dioxide and methane, making this lake the most dangerous lake on Earth. But the lake furnishes also many goods and services for surrounding populations and may soon become the most important energy supplier in the area. At the beginning of gas exploitation, the time has come for gathering the large amount of scientific information acquired during past and present research on Lake Kivu. The eleven chapters cover many aspects of the physics, geochemistry and biology of the lake, with a particular focus on the unique physical and geochemical features of the water column and on the ecological functioning of the surface waters. The impacts of the introduced fish species and the potential impacts of methane exploitation are also summarized. This multi-disciplinary book may also be used as an introduction to the limnology and biogeochemistry of large tropical lakes, as it covers various aspects of the physics, geochemistry, biology and ecology of the African Great Rift lakes. "

The authors in this volume make a case for LTSER s potential in providing insights, knowledge and experience necessary for a sustainability transition. This expertly edited selection of contributions from Europe and North America reviews the development of LTSER since its inception and assesses its current state, which has evolved to recognize the value of formulating solutions to the host of ecological threats we face. Through many case studies, this book gives the reader a greater sense of where we are and what still needs to be done to engage in and make meaning from long-term, place-based and cross-disciplinary engagements with socio-ecological systems."

This anthology surveys the ecological impacts of the First World War. Editors Richard P. Tucker, Tait Keller, J. R. McNeill, and Martin Schmidt bring together a list of experienced authors who explore the global interactions of states, armies, civilians, and the environment during the war. They show how the First World War ushered in enormous environmental changes, including the devastation of rural and urban environments, the consumption of strategic natural resources such as metals and petroleum, the impact of war on urban industry, and the disruption of agricultural landscapes leading to widespread famine. Taking a global perspective, Environmental Histories of the First World War presents the ecological consequences of the vast destructive power of the new weaponry and the close collaboration between militaries and civilian governments taking place during this time, showing how this war set trends for the rest of the century.

Von den s damerikanischen Kulturen ist gew hnlich nur diejenige des Inkareiches ins kollektive Bewusstsein gedrungen. Deren kurze, aber intensive Erfolgsgeschichte und ihr spektakul res Ende verdecken die Tatsache, dass auch schon vor ihnen hochentwickelte politische und religi se Strukturen bestanden haben. Sie zu vernachl ssigen, w re dasselbe, als wollte man die antike Geschichte allein durch das r mische Reich repr sentiert sehen, unter Weglassung der griechischen, gyptischen und vorderasiatischen Reiche und Kulturen. Das vorliegende Buch behandelt eine dieser vorinkaischen Kulturen, diejenige der Mochica im Gebiet des heutigen Peru, die immerhin beinahe ein Jahrtausend (vom 1. vorchristlichen Jahrhundert bis ca. 800 n. Chr.) existiert hat und dann aus unbekannten Gr nden zusammenbrach. Am wahrscheinlichsten ist eine Umweltkatastrophe infolge des El-Ni o-Ph nomens. Die methodische Schwierigkeit der vorliegenden Studie liegt darin, dass sie (bzw. die ihr zugrundeliegende Sekund rliteratur) sich ausschlie lich auf arch ologische Quellen (Wandritzungen und Keramik) st tzen muss, deren Interpretation als Extrapolation aus den inkaischen Verh ltnissen bzw. deren Darstellung aus der Conquistazeit erfolgen muss. Der Autor ist sich dieser Problematik sehr wohl bewusst und thematisiert sie auch. Den Zugang zur Kultur der Mochica sucht er ber die Religion, die ja von den "staatlichen" Strukturen nicht zu trennen ist. Ausf hrlich wird dabei der 1987 erfolgte sensationelle Fund des F rstengrabes von Sip n behandelt. Er geht den Fragen nach, die sich dadurch zwangsl ufig ergaben: Welche tats chliche Bedeutung hatte die Religion? Welche Machtverh ltnisse ergaben sich daraus und welche Rolle spielte dabei die Kunst? Wesentliche Grundlage seines Urteils bilden nicht nur eigene Recherchen vor Ort, sondern auch seine methodische Vorsicht und Sorgfalt sowie die geschickte Auswahl von anschaulichem Bildmaterial.
