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

半干旱的澳大利亚牧场是对退化和气候变化最敏感的地区之一，特别是在水文学和生态学方面。我们在这些环境中的预测能力相当差，然而，气候变化(特别是降雨制度的变化)预计会加剧植被格局，加剧侵蚀和减少径流。该项目将开发一个模型框架，以便更好地了解这些自然(气候变化和变化)和人为(放牧、砍伐森林)干扰对这些地区的径流和侵蚀的影响。

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.
