Thilak Mallawaarachchi, recently returned to the Group wholly, upon concluding his long and productive association with the Australian Bureau of Agriculture and Resource Economics and Sciences (ABARES). His research encompasses economic, environmental and social aspects of resource management and focuses on using integrated modelling tools that link scientific data with economic frameworks to facilitate learning and problem solving.
His current work focuses on understaning the motives for adaptation under increasing uncertainty and examining viable pathways to improve agricultural productivity for enhanced food security in smallholder farming systems in east and southern Africa. he received the Australian Agricultural and Resource Economics Society Ph.D award in 2001 for bioeconomic modelling combining mathematical programming and choice modelling. He has published widely on various resource policy issues including water, land use planning, land degradation and the use of choice modelling and geographical information systems for resource policy. Thilak's work in the Group helped extend the Murray-Darling Basin Model to examine adaptation patterns in irrigated farming systems facing reduced water availability in the Basin. Aim is to understand the production-environmental tradeoffs for Basin water uses under different institutional arrangements in particular water trading and salinity mitigation when water supplies are both uncertain and variable across the Basin.
