About us

LEMG working group in front of a tree.

Our team is interested in how land ecosystems, climate change and land-use change interact globally and regionally. We explore through a range of modelling approaches challenges and solutions to sustainable development arising from land system dynamics. We are based at the Campus Alpin of the Karlsruhe Institute of Technology, located in the town of Garmisch-Partenkirchen in Southern Germany.

Land-climate-interactions

How do land and climate interact? Climate is a chief co-determinant of vegetation cover and carbon, water and nutrient cycles. Climate change, including the increasing levels of CO2 in the atmosphere, therefore will cause biomes’ boundaries to shift, and impact biodiversity and numerous processes in terrestrial ecosystems.

Ecosystem functional diversity and services

Life together with climate and other abiotic drivers is the basis to the state and functioning of the ecosystems. Although we do not fully understand the entirety of consequences of our doing, humanity is exploiting, in many places over-exploiting, ecosystems around the world: to gather resources, as space for human living, and for agriculture, forestry, and many other forms of use.

Impacts and future of land use

Land provides the basis for our livelihoods – but the current extend of human influence, magnitude and rate of change of resource use is historically unprecedented and not sustainable. The way humans make use of terrestrial ecosystems clearly will have to improve, especially since changing climate and rising CO2 concentrations will become additional key factors, which affect growing conditions for crops, pastures, and forests.

Herbivory Introduction to LPJ-GUESS

Jens, Almut, Peter and Moritz, together with Mike Harfoot, have published a version of LPJ-GUESS which implements herbivory. The corresponding reduction in leaf biomass is determined by a process-based, dynamic model of the whole trophic pyramid (the Madingley Model).

The biodiversity-climate-food nexus

Almut led the study "The biodiversity-climate-food nexus: Illustrating challenges and solutions using the Green Shoots framework" in One Earth. It highlights the importance of coordinating environmental policies and their implementation to avoid trade-offs and to use synergies across different sustainability goals.

How can international agricultural trade contribute to biodiversity conservation, climate protection, and food security?

Almut was a member of the writing team for this Leopoldina discussion paper. The study outlines ways in which international agricultural trade can be structured in such a way that it contributes equally to achieving food security, climate goals, and biodiversity goals.
