The 2024 Food Waste Index Report, published by the United Nations, has revealed a staggering disconnect in the global food system, noting that approximately 1.05 billion tonnes of food are wasted annually despite 783 million people facing chronic hunger. This volume of waste represents nearly 19 percent of all food available to consumers worldwide. From a macroeconomic perspective, the report estimates that food waste costs the global economy approximately $1 trillion every year, driven by significant losses across retail outlets, food service operations, and private households.
For Nigeria, these global findings carry urgent domestic implications. United Nations estimates suggest that about 35 million Nigerians could face severe hunger by 2026, a crisis exacerbated by the country’s high headline inflation, which has seen food prices surge by over 35 percent in recent years. The economic cost of waste in Nigeria is not merely a loss of capital but a direct threat to national food security and social stability. As the most populous nation in Africa, Nigeria’s inability to bridge the gap between food production and consumption efficiency continues to strain its foreign exchange reserves, as the country remains reliant on food imports to supplement domestic shortages.
The report provides a granular breakdown of where these losses occur, noting that households are the primary contributors to global food waste, generating 631 million tonnes annually. This equates to an average of 79 kilograms of food wasted per person each year. The food service sector follows with 290 million tonnes, while the retail sector accounts for 131 million tonnes. In developing economies like Nigeria, these household losses are often compounded by poor storage infrastructure and an inconsistent power supply, which leads to the rapid spoilage of perishable items such as tomatoes, peppers, and leafy vegetables before they can be consumed.
Beyond waste at the consumer level, the United Nations highlights that an additional 13 percent of food produced globally is lost during the post-harvest stage. This post-harvest loss reflects deep-seated inefficiencies across the supply chain, particularly in transportation and primary storage. This systemic failure occurs while approximately 150 million children under the age of five suffer from stunted growth due to a lack of essential nutrients. In the Nigerian context, the “farm-to-table” journey is fraught with logistical bottlenecks, where poor road networks and the lack of cold-chain logistics mean that a significant portion of agricultural output never reaches urban markets in viable condition.
The report distinguishes between the Food Loss Index, which monitors production and transport, and the Food Waste Index, which focuses on the consumption stage. Crucially, the Food Waste Index allows nations to measure waste generated during manufacturing processes, providing a more comprehensive view of industrial efficiency. The UN identifies food waste as a predominantly urban issue. With over half of the global population now residing in cities a trend mirrored by Nigeria’s rapid urbanization local governments are becoming the frontline actors in waste management. Urban centers like Lagos and Kano face mounting pressure to develop sophisticated organic waste recycling systems to mitigate the environmental and economic impact of discarded food.
To address these challenges, the report advocates for intensified collaboration between the public and private sectors. Public-Private Partnerships (PPPs) are identified as the most effective mechanism for overcoming the fragmentation of the food system. By bringing together farmers, logistics providers, retailers, and policymakers, these partnerships can drive the adoption of innovative technologies, such as solar-powered storage and digital inventory tracking, which reduce spoilage. For Nigeria, fostering a pre-competitive space where businesses can share best practices could lead to a more resilient food architecture, reducing the fiscal burden of food inflation on the average household.
The environmental consequences of food waste also intersect with global climate goals. Food that rots in landfills produces methane, a potent greenhouse gas, making food waste a significant contributor to global emissions. Reducing waste is therefore essential not only for economic efficiency and hunger alleviation but also for meeting international climate commitments. As nations move toward the 2030 Sustainable Development Goals, the reduction of food waste is viewed as a “triple win” that improves resource efficiency, enhances food security, and protects the environment.
Looking toward 2026, the trajectory of Nigeria’s food security will depend largely on its ability to domesticate the recommendations of the UN report. Implementing cold-chain infrastructure and providing tax incentives for companies that invest in food preservation technology will be critical. If the current levels of waste remain unchecked, the projected 35 million people facing hunger will likely increase, further dampening Nigeria’s GDP growth and increasing the government’s expenditure on emergency social interventions.
