Ellis ist Professor für Geologie und Umweltsysteme an der University of Maryland und Mitglied einer Kommission, die die Einführung des Begriffs Anthropozän als geologisches Erdzeitalter untersucht hat. Der Begriff geht u.a. zurück auf den Nobelpreisträger P.J. Crutzen: "Das Anthropozän"....

The economics of CO2 capture and storage in relation to the possibility of significant leakage of CO2 from geological reservoirs once this greenhouse gas has been stored artificially underground will be among the main determinants of whether CCS can significantly contribute to a deep cut in...

This thesis, written within the Cluster of Excellence Exc264 Topoi, applies central place theory in archaeological context in order to investigate the influence of natural environmental characteristics on the formation, development, and persistence of central places. To allow an application of...

Conservation of high-biodiversity tropical forests is sometimes justified on the basis of assumed hydrological benefits - in particular, the reduction of flooding hazards for downstream floodplain populations. However, the "far-field" link between deforestation and distant flooding has been...

Brian Frehner is an assistant professor of history at Oklahoma State University. He received a Bill and Rita Clements Post-Doctoral Research Fellowship for the Study of Southwestern America in 2004-5 and is the coeditor of Indians and Energy: Exploitation and Opportunity in the American Southwest.

The Mekong River is the dominant geo-hydrological structure in mainland Southeast Asia, originating in China and flowing through or bordering Myanmar, Laos, Thailand, Cambodia, and Vietnam. Whereas water resources in the wet season are more than adequate to fulfill basin needs, there are...

A key challenge in the development of safety cases for the deep geological disposal of radioactive waste is handling the long time frame over which the radioactive waste remains hazardous. The intrinsic hazard of the waste decreases with time, but some hazard remains for extremely long periods....

Safety assessments of disposal sites for radioactive waste involve analyses of potential releases of radionuclides from the disposed waste and subsequent transport to the human environment. An important stage of assessment is the identification and documentation of all the features, events and...

One of the challenges facing the continued availability of nuclear energy is that of ensuring the safe, environmentally acceptable and economic management of the waste generated during its production. There is a broad scientific and technical consensus that disposal of high-level, long-lived...
