Department Systems Analysis, Integrated Assessment and Modelling

Water, Environment and Food Security

The group ‘Water, Food and Environmental Studies’ conducts integrated analysis and modeling of water, food and environment relations involving natural and social sciences at the local, river basin, national and global level. We also contribute to teaching on related topics at Basel University.

We have two major research focuses:

Modeling water-food-environmental relations

Development and application of qualitative and quantitative/modeling tools to analyze water, food and environment relations.

Application of a Spatially Explicit Bio-physical Crop Model to Assess Drought Impact on Crop Yield and Crop-Drought Vulnerability in Sub-Saharan Africa.
With continuing population growth, increasing affluence and economic development, and diet change towards more meat consumption, the demand for food will also increase.
