Food waste and loss present significant challenges globally, with Nigeria being particularly affected. This study comprehensively analyzes the causes, effects, and potential solutions to food waste within the Nigerian context. Drawing on extensive research and secondary data sources, the study highlights the pervasive nature of food waste, focusing on key sectors such as tomato, onion, and chili production. It identifies critical factors contributing to food waste, including inadequate infrastructure, pests and diseases, transportation constraints, and policy gaps. The socioeconomic impacts of food waste, such as increased food prices, exacerbated poverty, and environmental degradation, underscore the urgency of addressing this issue. However, amidst these challenges lie opportunities for intervention. Nigeria can significantly reduce food waste, enhance food security, and promote economic development by implementing a holistic approach that encompasses infrastructure development, sustainable agricultural practices, and supportive policies. Additionally, individual actions, such as meal planning and supporting local farmers, play a crucial role in mitigating food waste at the grassroots level. Through collaborative efforts involving governments, businesses, civil society, and individuals, Nigeria can pave the way towards a more resilient and sustainable food system, ensuring equitable access to nutritious food while preserving the environment for future generations. The methodology employed in this study entailed data collection primarily from prior research and secondary sources such as published studies, newspapers, articles, and relevant materials. The study’s focal point centered on food waste and loss, with a specific focus on vegetable waste within the Nigerian context.
