Use & Management

Freshwaters are used in many ways: as a drinking water supply, for industrial transportation and for recreation. All these functions, also referred to as ecosystem services, can only be ensured if rivers and lakes are in a good ecological state. Since its introduction in 2002, the Water Framework Directive has called for just that. And yet water is a scarce resource in many regions of the world. The growing pressure caused by mining, industry, hydroelectric power production and agriculture affects water quality and the passage of freshwaters. At IGB, we develop concepts for the future-oriented management of freshwater resources for the welfare of humans and nature. We investigate how anthropogenic influences affect freshwaters, and how lakes, flowing waters and wetlands can be used sustainably and revitalised efficiently.

Woody riparian buffer strips along rivers have widely been used mainly to reduce nutrient and fine sediment input from agricultural areas but potentially offer many more ecosystem services (e.g. habitat provision increasing biodiversity, shading and temperature regulation, mitigating climate change effects).
