Climate Impact Research

Wheat yield variation with two degrees temperature variation (Asseng, S., Ewert, F., Martre, P. et al. Rising temperatures reduce global wheat production. Nature Clim Change 5, 143–147 (2015). https://doi.org/10.1038/nclimate2470).

At our chair, we are strongly committed to study the impact of climate change on wheat cultivation. Droughts, excessive rainfall, or waterlogging can be very harmful for crop production. These events are expected to become more extreme and more frequent with advancing climate change. On field level, we use crop simulation models to understand how farm management needs to be adjusted to overcome the challenges of climate change. This includes cultivar selection, fertilizer optimization, or planting and harvest times. In addition, we study the impact of climate change on wheat production at national or global level. Based on current estimates, global wheat production will be more variable as more major breadbasket regions will suffer crop failures simultaneously with advancing climate change. A study conducted by Prof. Asseng (Asseng et al., 2015) indicated that rising temperatures can cause global yield reductions with harmful consequences for food security. To counteract these risks, we develop statistical and machine learning methods to model the relationship between climate and wheat production.
