Bella Blanche writes about spending time on the vast Macfarlane Station in Tambo, Queensland and introduces a methodology to assess risks posed by climate change, and the vulnerability of the native rangeland resources located west of the Great Dividing Range.

The past four months since out last newsletter has been tightly packed with the official launch of CLEX, the legacy event for ARCCSS and an acceleration in important research across all of our programs.
Research has now begun in earnest in the Drought Research Program with all key staff finally in place. This has proved timely. At the time of writing (August 2018) most of NSW has been drought declared and forecasters suggesting little sign of drought-breaking rains over coming months.
A new study by CLEX researchers using observations from FLUXNET sites identifies regions of high and low predictability and will likely help improve land surface model evaluation.
New research clearly demonstrates the potential to predict long-term LAI using simple ecohydrological theory. This approach could potentially be incorporated into existing terrestrial biosphere models and help improve predictions of LAI.
The application of a simple carbon balance model, combined with a data assimilation approach, has the potential to improve the process understanding embedded in models, which is used to predict responses of the carbon cycle to climate change.
This project will connect plant water use and stomatal conductance models differentiated by vegetation-soil systems with land surface models to provide new insight into the impacts of the built environment on moisture fluxes that influence heatwave intensity. Then it will investigate the climate impacts of the dynamic response of greenery in extreme heat conditions.
New research published in Nature Geoscience has found that climate engineering that modifies the properties of the land surface in highly populated areas and agricultural areas over North America, Europe and Asia could reduce extreme temperatures there by up to 2-3°C.
The reduction in growth of plants restricted by limitations on nutrients, temperature and/or water stress, didn't just reduce photosynthesis but led to negative feedbacks in plant carbon balance processes.
This study explored the key sources of uncertainty when scaling leaf-level understanding of water-use efficiency to ecosystem scales. The results provide key insights into interpreting (ecosystem-scale) eddy-covariance derived water-use efficiency in an ecophysiological context.
