Land Change Science

Main menu

Landscapes change over time, shaped by natural processes, such as erosion and succession, and anthropogenic influences, such as agricultural or forestry activity, construction activity - in short: land use. Our research unit investigates this interplay of ecological and anthropogenic influences and its impact on landscape development.

The landscape level shows how sustainably society deals with natural resources - we use this for comprehensive analyses.

Our research and development activities are aimed at the national and international research community. It is equally important to us to carry out relevant research for the general public and to support public administration in fulfilling its tasks.
