During the past three decades, urban groundwater has emerged as one of the world’s most pressing issues. Explosive population growth, most prevalent in cities, has placed an inordinate demand on groundwater supply, prompting concerns for its long-term sustainability at a time when the quality of available groundwater resources is being increasingly degraded by anthropogenic activity. Cities less reliant on groundwater for potable supply are equally obliged to manage subsurface water with cautious respect since rising groundwater levels can generate a myriad of problems such as unstable land slopes, flooded basements, tunnels and electrical utilities, and the release of polluted water to urban wetlands, springs and streams. Challenges in Urban Groundwater is premised on a growing recognition that most urban groundwater problems are not uniquely associated with any particular region or hydrogeological environment, and much can be learned by understanding the successes and failures of others. It showcases the best urban groundwater papers presented at the International Geological Congress held in Florence, Italy in 2004, and is supplemented by contributions solicited from other world experts active in urban groundwater research. Topics covered range from the urban water balance and rising groundwater levels to groundwater contamination and the role of aquifer modelling.

Steven Stanleys Historische Geologie ist das umfassende Kernlehrbuch der PalAontologie fA1/4r angehende Geologen, aber auch Biologen und Geographen und, last but not least, auch Lehramtsstudenten in diesen FAchern. Die erste Auflage - immerhin A1/4ber 10.000 Exemplare - hat sich im deutschen Lehrbuchmarkt auf Anhieb behauptet und in der Neuauflage viele Verbesserungen durch Aktualisierung, aber auch inhaltliche PrAzisierungen erfahren. Insbesondere wurden zwei vAllig neue Kapitel zu den groAen StoffkreislAufen der Erde bzw. zur Erdentwicklung nach der groAen Vereisung im PleistozAn aufgenommen.
