Abstract
Food loss and waste are significant global issues that have a profound impact on food security, the environment, and the economy.
This review examines the magnitude, origins, and consequences of food loss and waste within the food system, emphasizing
both technical and socio-political
dimensions. Evidence suggests that losses occur at multiple stages, including production,
post-harvest
handling, retail, and consumption. The causes include inadequate infrastructure, poor handling practices, ineffective
supply chains, consumer behaviors, and weak regulatory frameworks. High-income
nations generate more waste during
consumption, whereas developing regions such as Sub-Saharan
Africa experience significant waste post-harvest
and throughout
distribution. Existing interventions, including the expansion of the cold chain, utilization of digital platforms, and implementation
of awareness campaigns, have proven to be inadequately scalable, particularly in resource-constrained
environments.
Moreover, inadequacies persist in data quality, behavioral research, policy enforcement, and the incorporation of circular economy
methodologies. This review is distinctive in that it examines the collective impacts on the environment, health, and economy,
correlating them with governance and cultural influences, particularly in developing nations. The findings underscore the
need for policies that are transparent, evidence-based,
and integrate food loss and waste reduction with national strategies for
food security, climate change mitigation, and public health. To achieve SDG 12.3 and enhance the sustainability of food systems,
it is crucial to strengthen data systems, promote private sector engagement, and foster innovations in the circular economy.
