Mots clés drylands ecohydrology desertification restoration vegetation patterns

I study the ecohydrological feedbacks between ecosystem structure and ecosystem functioning in drylands, and how climatic and human pressure may alter them. My research combines modelling, observational and manipulative experiments, including measurements from the field, lab, and aerial photographs. One of the main goals of my current research is the improvement of ecological realism in dryland vegetation models by developing stronger links between modelling and field experiments. Among other topics, I would like to use this research to contribute to knowledge on early-warning indicators of desertification, which often lack empirical testing and sufficient understanding of the mechanistic linkages between pattern and processes related to threshold changes.
