In 2015, the UN General Assembly unanimously adopted the Sustainable Development Goals (SDGs). Target 12.3 states the following: “By 2030, halve per capita global food waste at the retail and consumer levels and reduce food losses along production and supply chains, including post-harvest losses.” To create a sustainable society, reducing food waste and disposal throughout the Food Supply Chain (FSC) is necessary. Reducing the loss of vegetables and fruits is essential because they account for a significant proportion of losses and waste at each stage of distribution, retail, and consumption. In contrast, increasing the intake of vegetables and fruits is crucial for health. However, increasing vegetable intake is often challenging, and without proper utilization, vegetables can be wasted. Therefore, this study designed a digital game based on the vegetable supply chain to enhance consumer health awareness, increase vegetable intake, and develop a sustainable food supply chain.
