Abstract

Food waste (FW) has become a major concern in the global era, which is affecting the societal environment and economy consistently. Rising population and urbanization have increased food production and consumption, especially in developing countries like Bangladesh. Due to limited recycling and disposal choices, FW is composted, landfilled, and fed to animals, creating a dirty and smelly environment. Such a situation needs elevated awareness and attention among consumers. Following the necessity, this study investigates the impact of consumer awareness on reducing FW in households and restaurants. Here, the partial least square structural equation modelling (PLS-SEM) was utilized to predict the factors that affect consumers behaviors relative to FW at household and restaurant levels. Two PLS-SEM were estimated, a normative and an explicative model. In the normative model, three multidimensional attitude components (affective, cognitive, and conative) were classified among the factors that influence food waste behaviour. The conative component was found to be the most influential. In the explicative model, improper meal storage emerged as the factor with the highest correlation with the generation of FW. The implication of this research encourages stakeholders to share research findings to work toward a sustainable and food-secure future.
利用偏最小二乘结构方程模型(PLS-SEM)方法提高消费者减少食物浪费的意识
食物浪费已成为全球关注的一个主要问题,它不断影响着社会环境和经济。人口增长和城市化增加了粮食生产和消费,特别是在孟加拉国这样的发展中国家。由于回收和处理选择有限,FW被堆肥,填埋,并喂给动物,造成了一个肮脏和难闻的环境。这种情况需要提高消费者的意识和关注。根据这一必要性,本研究调查了消费者意识对家庭和餐馆减少FW的影响。本研究利用偏最小二乘结构方程模型(PLS-SEM),从家庭和餐厅两个层面预测影响消费者FW行为的因素。估计了两个PLS-SEM,一个是规范性模型,一个是解释性模型。在规范模型中,三个多维态度成分(情感、认知和意向)被归类为影响食物浪费行为的因素。研究发现,创造性成分是最具影响力的。在解释性模型中,膳食储存不当是与FW产生相关性最高的因素。这项研究的意义在于鼓励利益相关者分享研究成果,为实现可持续和粮食安全的未来而努力。
