Introduction

Food loss and waste pose pressing global threats, undermining food security, economic welfare, and environmental health. Each year, about one-third of all food produced for human consumption, around 1.3 billion metric tons is lost or wasted worldwide. This massive inefficiency persists amid rising hunger, with nearly 690 million people undernourished in 2019 and approximately three billion unable to afford nutritious diets. If food waste were a country, it would rank as the third-largest greenhouse gas emitter, responsible for 8 to 10 percent of global emissions, largely from methane generated by decomposing food.

Patterns of Loss in Africa and Cameroon 

Food loss patterns vary by region. In wealthier countries, waste mostly occurs at the consumer level due to over-purchasing and discarding edible food. Conversely, African nations such as Cameroon experience most losses early in the supply chain, in post-harvest handling, storage, and transport. Africa loses about 22 percent of its annual food production, causing nearly $92 billion in economic losses and worsening food insecurity for 320 million people in Sub-Saharan Africa. Cameroon clearly reflects these challenges. Approximately 30 to 40 percent of maize is lost post-harvest due to poor storage, pests, and transports issues. Losses of tomatoes and leafy greens reach 40 percent, while processed cassava products suffer up to 72 percent value loss during storage. Unlike wealthier nations where consumer waste dominates, Cameroon’s losses chiefly occur “from farm to market”.

Causes and Consequences 

Several factors drive this pervasive problem. Infrastructure deficits are a critical cause; limited paved rural roads hinder timely market access, and unreliable electricity supply prevents the development of a cold chain for perishable goods. Traditional storage methods also remain vulnerable to pests and mould. This lack of robust infrastructure, combined with a deficit in farmer knowledge on effective handling and storage techniques, leads to elevated rates of spoilage. The consequences are far-reaching. Economically, food loss can reduce farmer incomes by up to 15%, trapping rural populations in poverty. Environmentally, it represents a massive waste of land, water, and energy used for production, and its emissions exacerbate climate change. Socially, it compounds malnutrition and food insecurity, disproportionately affecting vulnerable groups.

Pathways to Solution

Combating food loss in Cameroon requires integrated solutions that combine technology, education, and policy reform. Upgrading storage infrastructure with modern, pest-resistant technologies like silos and hermetic bags is essential. Simultaneously, investments in rural roads and reliable power are necessary to build effective cold chains. Educational training programs are also crucial for teaching farmers, particularly women and smallholders, best practices in harvest handling and storage. On a policy level, embedding food loss reduction into national development strategies and supporting agro-processing industries can strengthen the entire food system. 

Conclusion

Food loss and waste in Cameroon and Africa highlight the paradox of scarcity amid plenty. Through well-coordinated investments in infrastructure, education, and policy, losses can be drastically reduced, improving food security, incomes, and environmental sustainability. The time for decisive, urgent action is now, with immense potential benefits for Cameroon’s people and the planet.
