Globally, food waste is a significant environmental, economic and social issue. Food waste in landfill creates the potent greenhouse gas, methane, contributing to climate change, with its management predominantly falling to local governments. Despite efforts by many countries, and extensive infrastructure and market development funding, food waste continues to be landfilled, with apparently similar councils taking diverse approaches. Using a mixed methods study design, data was firstly collected from a National online survey of Australian council-based waste management staff (n = 183), with descriptive and factor analysis of the survey data revealing a strong sense of structural empowerment (PCA.75 to.90) and a preference for sourcing information from networks (48%). These results informed a series of semi-structured interviews (n = 43) which, after thematic analysis, provided rich insights into the attitudinal and situational interpretations council-based waste managers bring to decisions around household food waste management. Framed by four pillars of Structural Empowerment, the findings suggest that waste manager's attitude is equally as important as support, resources, and knowledge and that, despite mandates and targets, individual motivational factors and organisational paradigms determined decision-making. Identified barriers included perceived capacity constraints, inadequate focus on actionable interventions, and fragmented, uninspiring, planning. This article provides important insights around 1) leveraging networks for knowledge dissemination, 2) fostering capacity-building initiatives, and 3) advocating for sustained engagement with food waste diversion within councils. This underscores the need for additional research into evolving council typologies and effectively engaging key stakeholders to achieve food waste diversion targets and address climate change impacts.
在全球范围内,食物浪费是一个严重的环境、经济和社会问题。垃圾填埋场中的食物浪费会产生强效温室气体甲烷,从而导致气候变化,而其管理主要由地方政府承担。尽管许多国家都做出了努力,并且在基础设施和市场开发方面投入了大量资金,但食物浪费仍在继续被填埋,显然类似的委员会采取了不同的方法。本研究采用混合方法研究设计,首先从澳大利亚基于委员会的废物管理工作人员的全国在线调查中收集数据(n = 183),对调查数据进行描述性和因子分析,揭示了强烈的结构赋权感(PCA.75 至.90),并且更喜欢从网络获取信息(48%)。这些结果为一系列半结构化访谈(n = 43)提供了信息,经过主题分析,深入了解了基于委员会的废物管理人员在家庭食物废物管理决策方面的态度和情境解释。由结构赋权的四个支柱框架,研究结果表明,废物管理人员的态度与支持、资源和知识同样重要,尽管有任务和目标,但个人激励因素和组织模式决定了决策。确定的障碍包括感知到的能力限制、对可操作干预措施的关注不足,以及分散、缺乏灵感的规划。本文围绕以下几个方面提供了重要的见解:1)利用网络传播知识,2)培养能力建设计划,以及 3)倡导在委员会内部持续参与食物浪费转移。这突显了需要进一步研究不断发展的委员会类型,并有效地吸引关键利益相关者,以实现食物浪费转移目标并应对气候变化的影响。
