Citizens’ deliberation on solutions to fight urban household food waste and nexus with growing urban gardens: The case of porto metropolitan area in Portugal

Résumé fourni par la source

Food waste is currently acknowledged as a major societal challenge, including the food waste at the household level estimated to be responsible for the wastage of one third of the food produced for human consumption. Hence, tackling household food waste (HFW) is gaining a momentum in societal and policy agendas accompanied by an increasing effort of the scientific community to deliver evidence to address the research gaps on the causes and on the solutions to address this multidimensional societal problem. The proposed solutions by published literature to mitigate HFW can be unfolded into four major types, actions to raise people awareness, participatory actions, economic incentives, and collective actions. However, there is little evidence on the household's assessment of the different types of actions and its combination. This paper contributes to this research gap by adopting an innovative participatory approach, using deliberative focus groups (DFG), and analyzing the collected data through content analysis resorting to the software Maxqda. We had conducted six DGF in the Porto metropolitan area before and during the pandemic COVID-19 crisis. Our results highlight the citizen's option for more holistic actions in comparison to separate actions as a way to effectively fight food waste at household level. Another finding of our study is that citizen's growing urban gardens found it the more effective way to reduce household food waste. These results suggest that urban policies and underlying legal frameworks should favor holistic solutions to incentivise fighting HFW and account for the urban gardens as a relevant part of the solution. In addition, the study has shown that qualitative deliberative citizen-led approaches show insightful to understand how common people perceive as alternative or complementary the different types of actions to fight HFW proposed by the literature review.
