Abstract

We discuss an explicit-space model for vegetation dynamics in water-limited ecosystems. Under conditions of water stress, vegetation patterns such as spots, stripes and gaps spontaneously emerge. In this contribution, we focus on the interplay between water-vegetation feedbacks and rainfall intermittency, and we discuss an extended version of the model which allows for studying how evapotranspirations fluxes are modified by the presence of patterns.
