Project 15

Feedbacks between vegetation and climate

About the project:

The project addresses the question of how changes in land cover and use, especially deforestation by means of fire, change the vegetation cover and atmospheric composition. To investigate and better understand these feedbacks between vegetation and the atmosphere we need to quantify the potential for an “Amazon tipping point”.


  • Improve the representation and feedbacks of vegetation in regional climate models (e.g. transpiration, albedo, CO2) and vice versa
  • Investigate effects of deforestation and fire on climate at a high spatial resolution
  • Evaluate scenarios for the tipping point analysis using network analysis
