Further information on the person


The vegetation covering the continents has decisive influence on climate, exchanging heat, moisture, momentum, and a variety of chemical materials with the atmosphere. Humans are substantially interfering with this exchange, having transformed three quarter of the ice-free land surface to managed lands, with severe effects on the Earth system; e.g., one quarter of current anthropogenic greenhouse gas emissions arise from land use. Effects are expected to become even stronger in the future, as demand for food and fibre rises in a more populous and affluent world, and as the international goal of limiting global warming to two degrees may rely on substantial additional CO2 sinks through land use. 

Our research assesses questions like this:

+ What were the effects of land use change over the last few centuries? A warming, because deforestation caused CO2 emissions and reduced transpiration? Or a cooling, because clearing dark forest made the land surface brighter?

+ How large are the potential of negative emission technologies such as af/reforestation or bioenergy with carbon capture and storage to take up and sequester CO2? How permanent is this carbon storage, could future extreme events annihilate a forest carbon sink? What are the risks and side-effects of NETs?

+ Is it possible to create win-win situations for mitigation and adaption by land use change such as afforestation, where we achieve a reduction in the global atmospheric CO2 concentration concurrently with a local cooling through energy and water fluxes?

+ How can we reduce the large uncertainties around land use emission estimates, integrating model simulations with Earth observations?

+ How can we integrate land management in global Earth system models to assess effects e.g. of forestry harvest and intensification on vegetation and climate?

To this end we combine and develop a range of tools: semi-empirical carbon cycle models (“bookkeeping models”), dynamic global vegetation models and Earth system/climate models, and integrate them with Earth observations (site-level, inventories, remote sensing).

Julia Pongratz is member of the Scientific Steering Committee of two Future Earth projects: the Global Carbon Project, in which she also coordinates land use emission estimates for the annual global carbon budget, and AIMES ("Analysis, Integration & Modelling of the Earth System”), in which she co-chairs the working group on human-Earth system interactions. She is also SSC member for two CMIP6 model intercomparison projects, C4MIP (“Coupled Climate Carbon Cycle MIP”), aiming at a better understanding of carbon cycle feedbacks, and LUMIP (“Land Use MIP”), which investigates projections of land use change and their effects on climate to 2100. Since 2021, she coordinates the synthesis of the BMBF Carbon Dioxide Removal programs.

For external projects see “Forschungsprojekte” below. Until 2021, Julia Pongratz has also been leading the joint research group on "Land use in the Earth system” at the Max Planck Institute for Meteorology, following an Emmy-Noether group on forest management.
