This report identifies major constraints to the adaptive capacity of  food organisations operating in Australia. This report is about food security, climate change and risk management.  Australia has enjoyed an unprecedented level of food security for more  than half a century, but there are new uncertainties emerging and it  would be unrealistic – if not complacent – to assume the same level of  food security will persist simply because of recent history. The project  collected data from more than 36 case study organisations (both foreign  and local) operating in the Australian food-supply chain, and found  that for many businesses,&nbsp; risk management practices require substantial  improvement to cope with and exploit the uncertainties that lie ahead.  Three risks were identified as major constraints to adaptive capacity of  food organisations operating in Australia:&nbsp; risk management practices;  an uncertain regulatory environment – itself a result of gaps in risk  management; climate change uncertainty and projections about climate  change impacts, also related to risk management
