Seasonally laminated lacustrine sediments of Lake Stadtsee located in the city of Bad Waldsee (Swabia) offer a unique archive of the economic and environmental history since medieval times. This allows correlating sedimentary signals with historic documents precisely to the year over centuries. The overall goal is to check if, when and how the history of a city and its periphery affected lake development and water quality, and how fast water quality and aquatic ecosystem recovered from human impact.An interdisciplinary research team consisting of geologists, biologists and historians is established to investigate temporally highly resolved records of diatom and pollen spectra, geochemical proxies and sediment facies of already available profundal sediment cores from Lake Stadtsee and to compare and calibrate these results with historic documents, stock books and maps. Research will focus on the effects of population growth or decrease, farming intensity, economic production, trade activity, climate change and catastrophic events such as fire and floods. We expect detailed information about the response of urban surface waters to changing emissions of the city and the long-term behavior of persistent pollutants on lakes. The project will contribute to the knowledge of historic human impact on the environment in Germany, reference conditions, and the resilience of aquatic systems. For the first time the environmental impact of socio-economic development for the preindustrial development phase of a city from AD 1200 to 1800 will be assessed.

位于巴德瓦尔德塞市(斯瓦比亚)的斯塔德西湖季节性层状湖泊沉积物为中世纪以来的经济和环境历史提供了独特的档案。这允许将沉积信号与历史文件精确地关联到几个世纪以来的一年。总体目标是检查一座城市及其周边的历史是否、何时以及如何影响湖泊的发展和水质，以及水质和水生生态系统从人类影响中恢复的速度有多快。一个由地质学家、生物学家和历史学家组成的跨学科研究小组被建立起来，以调查斯塔德塞湖已有的深海沉积岩芯的硅藻和花粉光谱、地球化学替代物和沉积相的时间高分辨率记录，并将这些结果与历史文献、存量书籍和地图进行比较和校准。研究的重点将是人口增长或减少、农业强度、经济生产、贸易活动、气候变化以及火灾和洪水等灾难性事件的影响。我们期待关于城市地表水对城市排放变化的响应以及持久性污染物在湖泊上的长期行为的详细信息。该项目将有助于了解德国历史上人类对环境的影响、参考条件和水生系统的恢复能力。将首次评估一座城市在公元1200年至1800年的工业化前发展阶段的社会经济发展对环境的影响。
