Land is a limited resource. Therefore ecosystem services will be limited, too. The challenge is to identify where ecosystem services are available, and if and how much renewable resource production can be increased. However, different ecosystem services might also trade off each other or show a synergetic pattern. Therefore, a simple either-or of protecting nature vs. use of resources is inappropriate for various regions in the world and limits opportunities for action. The challenge is rather to understand how land use determines these synergies and trade-offs and how optimum land use can be derived from this knowledge.
Utilising field observations, remote sensing data, and statistical analysis we develop and use integrated simulation models, which provide an understanding of the interactions of land use and ecosystem services. These models encompass water and matter dynamics, species distribution models and simple models of species interaction such as pollination and pest control. Scientists in the CLE Department utilise data from many regional case studies. Meta-analytic approaches help to assess how valuable regional research results are for a global scale research perspective. For this we identify key land system indicators that allow transferability of results. To do this, we use large volumes of data (including global data) and develop statistical procedures for regionalisation and to estimate how representative regional studies are for land use in a global context.In utilizing and applying the resolved knowledge, we support the development of options for the appropriation of limited, naturally renewed resources and ecosystems and prevent potential conflicts of use. Our objective is to use interdisciplinary collaboration and methods to develop management options for maintaining the productivity of our landscapes while at the same time safeguarding ecosystem functions and biodiversity.
