Cultivating climate change resilience in agri-food systems: responses to natural disasters and emerging climate risks in Queensland’s fresh produce supply chains

Abstract

Over the last decade, Australia has experienced several severe natural disasters which have caused significant disruptions to its agri-food supply chains. Global climate change is driving an increase in the frequency and intensity of extreme weather events that can lead to natural disasters. The Intergovernmental Panel on Climate Change (IPCC) warns that climate change -and extreme weather events, in particular -pose significant threats to food security. While much food security research focusses on developing nations, contemporary, supermarket-based food systems have a number of characteristics that make them highly vulnerable to disruptions from extreme weather events. The experience of recent disasters and projections of on-going climate change suggest that Australia's food systems are facing escalating climate risks to which they must adapt.This thesis considers how the agri-food supply chains that underpin Australia's food system are enabled or constrained to cope with emerging climate risks and, in particular, to a more rapid recurrence of damaging weather events. In this thesis, supply chains are The results of the study demonstrate that the impacts of recent natural disasters were unevenly distributed within the supply chain. Upstream segments of the chain (that is, business involved in vegetable production, packing and transport) experienced more significant impacts and longer recovery periods than downstream segments (such as wholesalers and retailers). The study finds that this is strongly linked to an uneven distribution of vulnerability to risks in the chain which, combined with the rapid recurrence of disaster events, has weakened the fresh produce supply system.ii The study provides important insights into perceptions, and social constructions, of recent weather events and climate risks amongst actors within fresh produce supply chainsaddressing a significant gap in the literature. The results suggest that a shared narrative about Australia's highly variable climate strongly influences a collective construction amongst supply chain actors which normalises and attenuates climate risk. The study finds, however, that recent extreme weather events have unsettled this dominant construct. Perceptions of future climate risks amongst supply chain actors were varied.Those strongly influenced by the climate variability narrative did not expect future risks to be much different from those experienced in the past. A smaller number of research participants, however, were concerned that climate risks may be escalating and that this may require changes to how those risks were managed.The study found two strongly contrasting approaches to the governance of climate risk in fresh produce supply chains. The findings demonstrate that, typically, climate risks are governed in highly individualised ways but that the emergence of new supply chain intermediaries is facilitating a more collective approach to climate risk governance in some chains. The research also shows that recent recurrent floods have catalysed...
