Every year on September 29, the world celebrates the International Day of Awareness of Food Loss and Waste (IDAFLW). The day is a global call to reconsider how food is produced, delivered, consumed and discarded.
The day was established by The United Nations to highlight a rising crisis where millions of people go hungry but a massive amounts of edible food are lost or wasted at every point of the supply chain.
Globally, 13% of food is lost post‑harvest, and 19% of food available to consumers is wasted, amounting to over 1.05 billion tonnes each year. This wasted food could feed more than 1.26 billion people, while also reducing pressure on land, water and biodiversity.

Understanding Food Loss & Food Waste
To address the problem effectively, it’s important to distinguish between food loss and food waste as the two are related but have different challenges.
- Food loss: Occurs before food even reaches retail shelves. It includes losses during harvesting, storage, transportation and processing.
- Food waste: Happens at retail, food service and household levels, often due to overbuying, poor storage or confusion around expiry labels.
However, both food waste and food loss contribute significantly to greenhouse gas emissions, resource depletion and rising food insecurity.
2026 Theme
The 2026 theme for the day is “Transformative Potential of Reducing Food Loss and Waste“. This emphasises the transformative power of reducing food loss and waste across agrifood systems. It highlights how small changes from farms to households can lead to:
- Improved food security and nutrition
- Reduced environmental pressure and greenhouse gas emissions
- Increased productivity and economic resilience
This theme aligns closely with SDG 12.3, which aims to halve global food waste by 2030. It encourages governments, businesses and individuals to adopt innovative solutions, embrace circular economy models and rethink how food is valued.
Why Food Loss & Waste Is a Global Emergency
The urgency of tackling food loss and waste becomes clear when looking at the numbers. In 2025, about 645 million people experienced hunger. Meanwhile, the economic cost of wasted food exceeds US$1 trillion annually.
Environmental impacts are equally severe as:
- Food waste contributes around 10% of global greenhouse gas emissions.
- It consumes vast amounts of land and water.
- It accelerates biodiversity loss through unnecessary agricultural expansion.
This shows that reducing food loss and waste is one of the most cost‑effective climate solutions available today.
Key Drivers Across the Supply Chain
Food loss and waste occur at every stage of the food system. Understanding these drivers helps identify where interventions can be most effective. For example:
- Production challenges: Climate impacts, poor storage and limited infrastructure.
- Processing & distribution: Spoilage, inefficient logistics and packaging issues.
- Retail practices: Overstocking, strict aesthetic standards and confusion around date labels.
- Household behaviours: Overbuying, poor meal planning as well as misunderstanding “use by” vs “best before”.
These drivers vary by region, income level and food type, making targeted solutions essential.
How Reducing FLW Transforms Agrifood Systems
Reducing food loss and waste (FLW) is not just about saving food but also about reshaping food systems to be more sustainable, resilient and equitable.
Key transformation pathways include:
- Circular economy innovations: Turning by‑products into new food items, compost or bioenergy.
- Digital tools: AI‑driven forecasting, smart storage sensors and improved logistics.
- Community redistribution networks: Connecting surplus food with charities and households.
- Policy and regulation: National food waste strategies, incentives for businesses and clearer labelling.
- Economic benefits: Reduced costs for farmers, retailers and consumers.
These changes strengthen food systems and reduce vulnerability to climate shocks.
Global Actions & Initiatives
International Day of Awareness of Food Loss and Waste is marked by global events led by FAO and UNEP, including conferences, workshops and awareness campaigns. Governments, NGOs and businesses participate through:
- National food waste reduction strategies
- Public awareness campaigns
- Community redistribution programmes
- Educational toolkits and school activities
The EU’s Food Loss and Waste Prevention Hub and similar regional initiatives continue to drive innovation and collaboration.
What Can Individuals Do
While systemic change is essential, individuals play a powerful role in reducing food waste at home by taking practical steps such as:
- Smarter shopping and meal planning
- Proper storage techniques
- Understanding food labels
- Creative cooking with leftovers
- Supporting local redistribution schemes
Conclusion
Reducing food loss and waste is one of the most impactful steps we can take toward a sustainable future. It strengthens food security, protects the planet and supports economic resilience.
On this International Day of Awareness of Food Loss and Waste, every action you take counts. Whether through policy, innovation or everyday habits, we all have a role to play in transforming our food systems.
