About the Presenter

Dr Mark Broich, Research Fellow at the School of Biological, Earth and Environmental Sciences, UNSW, Sydney

Dr Mark Broich is a remote sensing scientist with a research focus on vegetation dynamics and vegetation cover change in support of ecosystem and climate change research, land management and carbon trading policy applications. Mark uses time series of earth observing satellites to quantify and characterise environmental change over time and across large areas.

Mark holds a PhD in Geospatial Science and Engineering from the Geographic Information Science Center of Excellence, South Dakota State University (USA).

His PhD work quantified annual forest cover loss across the humid tropics and was picked up by the European Commission’s Environment News Alert service in relation to the REDD policy initiative.

Since relocating to Australia, Mark developed a GIS bush fire threat analysis for the entire state of Western Australia, and quantified surface water dynamics across the southwest of Australia, which is subject to a drying climate. 

Mark has developed the first Australian Phenology Product characterising vegetation dynamics across the driest inhabited continent and is currently working on quantifying vegetation response to flooding across the Murray Darling Basin as a research fellow on an ARC linkage project with Dr Mirela Tulbure.

Dr Mark Broich is currently a Research Fellow at the School of Biological, Earth and Environmental Sciences, UNSW, Sydney.

Deriving phenological cycles from satellite image time series represents an effort for end users. Existing global products do not accommodate conditions in Australia and its vast drylands. To fill this information gap we developed a model and derived the MODIS Australian Phenology Product in contribution to the AusCover Facility of the Australian Terrestrial Ecosystem Research Network. http://www.auscover.org.au/xwiki/bin/view/Product+pages/Phenology+MOD13C2+UTS

The product provides an internally consistent quantification of phenological cycles of vegetation dynamics that can inform agricultural applications, land surface modeling, ecosystem research and climate change studies.

Based on the Australian Phenology Product we characterised high inter- and intra-annual variability of phenological cycles across Australia between 2000 and 2013 and linked these spatial-temporal variability patterns with remotely sensed rainfall and atmospheric circulation indices (e.g., SOI). This resulted in a spatially explicit representation of extreme vegetation productivity response to regional climatic variability highlighting the transition between El Nino droughts to La Nina floods in 2011.
