Role of vegetation patchiness and self organisation in the ecohydrologic response of water limited ecosystems to climate variability and change

The semi-arid Australian rangelands are some of the most sensitive regions to degradation and climate change, particularly with respect to hydrology and ecology. Our predictive ability in these environments is quite poor, however, climatic change (particularly changes in rainfall regimes) are expected to intensify vegetation patterning, intensify erosion and reduce runoff. This project will develop a modelling framework to better understand the impact of these natural (climate variability and change) and anthropogenic (grazing, deforestation) disturbances on runoff and erosion in these regions.
