Creating sustainable and resilient urban food systems: A study of Australian alternative food networks

Abstract

Food systems are vulnerable to the impacts of resource scarcity, climate change, and population growth, as well as the issues associated with unsustainable social, environmental and economic practices. These challenges have encouraged local food systems as an alternative to global supply chains. This thesis studies this trend at the urban level in order to explore issues and opportunities for change. It argues that urban food systems need to embrace both sustainability and resilience. A sustainable urban food system has an economy that serves social needs while safely operating within ecological limits. Resilience, on the other hand, includes the ability to recover from shocks such as extreme weather events, as well as the capacity to adapt and ultimately transform in response to the ongoing impacts of climate change. The main research question that this thesis investigates is “How can alternative food networks help to foster sustainable and resilient urban food systems considering climate change and increased urbanisation?” A comparative case study approach was used involving local initiatives in the Brisbane and greater Melbourne metropolitan regions (Australia). Both Australian urban areas have similar economic development; however, differences can be found in terms of institutional interest and the existence of food policies. The gathering of a diverse picture of alternative food networks was the strategy adopted for selecting the initiatives that participated in this research. The criteria that alternative food networks should attend were the existence of goals related to access to healthy food, fairer conditions for food workers, and reduction of environmental impacts. The thesis used multiple sources of data including primary (semi-structured interviews with founders or members of initiatives and field observation) and secondary data (publicly available documents such as annual reports). The findings of this research contribute to the conceptualisation and planning of sustainable and resilient urban food systems, as well as, to the knowledge on the role and limitations of alternative food networks in achieving this. The case study conducted in this thesis revealed how alternative food networks can contribute to the creation of food provision systems that are aligned with environmental sustainability and social justice. The thesis exposed the particularities of initiatives that, among other aspects, have minimal food loss and waste, supports agroecology, provides farmers with fair payment and makes organic food affordable. Alternative food networks demonstrated to have resilience building capacity, something that is not confined to its borders and can impact on the whole urban food system. Alternative food networks’ values travel and allow the replication and creation of new models, however, not in the pace necessary for a wider urban food system transformation. The main challenge exposed by this thesis for alternative food networks is the need for scaling up by influencing institutions and policies more broadly.
