Every year, a staggering portion of the world’s food supply is lost or wasted, even as millions of people face hunger and food insecurity. The International Day of Awareness of Food Loss and Waste, observed on 29 September, calls on individuals, businesses, and governments to rethink how we produce, distribute, and consume food. It is a global reminder that saving food means saving resources, protecting the environment, and creating a sustainable future.
Introduction
The International Day of Awareness of Food Loss and Waste is more than a date on the calendar—it is a powerful global initiative spearheaded by the United Nations to draw attention to one of the most pressing challenges of our era. According to the Food and Agriculture Organization (FAO), approximately 1.3 billion tons of food—nearly one-third of all that is produced globally—is lost or wasted every single year. This is not only a humanitarian concern but also an environmental and economic crisis.
Food loss occurs at early stages of the supply chain, often due to inefficient harvesting methods, poor storage, and transportation challenges. On the other hand, food waste primarily happens at the retail and consumer level, driven by over-purchasing, confusion about food labeling, and cultural habits of discarding perfectly edible items. Together, they form a dual crisis that affects nutrition, resource management, and the fight against climate change.
Why This Day Matters
Highlighting the Scale of Food Waste
The numbers are staggering: almost 14% of food produced globally is lost between harvest and retail, while a further 17% is wasted at the household, food service, and retail levels. Food loss and waste contribute to 8–10% of global greenhouse gas emissions, a figure that rivals the transportation sector. When food is discarded, all the resources used to produce it—land, water, energy, and labor—are wasted too.
Addressing Human Needs
Food waste isn’t just about spoiled groceries; it’s about missed opportunities to fight hunger. Over 735 million people face hunger daily, while millions more suffer from malnutrition. By reducing food loss and waste, humanity could redirect vital resources to communities in need. A reduction of even 25% in food waste could feed 870 million people worldwide, bridging a critical gap between abundance and hunger.
Key Causes of Food Loss and Waste
Food Loss in Production and Distribution
Food loss often happens long before food reaches the plate.
- Harvesting Challenges: Crops are sometimes left unharvested due to low market prices or lack of labor.
- Storage Issues: Inadequate refrigeration and improper storage facilities spoil perishable goods.
- Transportation Problems: Poor infrastructure in developing regions leads to damaged or lost produce.
- Processing Inefficiencies: Food discarded during cleaning, packaging, or sorting processes.
Food Waste at Retail and Consumer Levels
On the consumer end, waste is driven by lifestyle and behavioral factors.
- Over-purchasing: Buying more than needed due to bulk discounts or poor planning.
- Expiry Confusion: Misinterpreting “best before” and “use by” labels.
- Plate Waste: Throwing away leftovers in restaurants and households.
- Cosmetic Standards: Discarding misshapen or “ugly” produce even though it’s edible.
Environmental and Economic Impact
Food loss and waste is not only a humanitarian concern but also a pressing environmental and financial challenge with far-reaching consequences. Every time food is thrown away, the resources used to produce it—land, water, energy, labor, and capital—are also wasted. This creates a devastating cycle where natural ecosystems are strained, climate change accelerates, and billions of dollars are lost worldwide. Understanding these impacts highlights why reducing food waste is a global priority.
- Environmental Damage: Food waste in landfills generates methane, a greenhouse gas 25 times more potent than carbon dioxide. Agriculture, already a significant emitter, becomes even more unsustainable when its output is wasted.
- Water and Land Use: Around 250 km³ of water—enough to meet the needs of 100 million people—is wasted annually in food that never gets eaten. Additionally, nearly 30% of agricultural land is used to produce wasted food.
- Economic Costs: Globally, food waste costs approximately $1 trillion every year, affecting economies at all levels—from farmers to consumers.

7 Frequently Asked Questions
Q1. What is the International Day of Awareness of Food Loss and Waste?
The International Day of Awareness of Food Loss and Waste is a United Nations–designated observance held every year on 29 September. Its purpose is to highlight the global challenge of food loss and waste, which affects food security, the environment, and economies worldwide. The day calls for urgent action from governments, businesses, communities, and individuals to adopt sustainable practices that reduce waste and make better use of food resources.
Q2. Why is food waste a global concern?
Food waste is a global issue because it impacts multiple dimensions of life. When food is wasted, the resources used in its production—such as water, land, and energy—are also wasted. Decomposing food generates methane, contributing to climate change. At the same time, millions of people go hungry despite an oversupply of food. Economically, food waste represents billions of dollars in losses annually, making it both a humanitarian and ecological crisis.
Q3. What’s the difference between food loss and food waste?
Food loss and food waste are related but distinct concepts. Food loss generally occurs during production, storage, and transportation—before food even reaches the consumer. It is common in developing regions where infrastructure may be inadequate. Food waste, on the other hand, happens at the retail or household level when edible food is discarded due to over-purchasing, confusion over expiry dates, or poor consumption habits. Together, they represent a major global challenge.
Q4. How does reducing food waste help the environment?
Reducing food waste has a direct positive impact on the environment. When less food is wasted, fewer greenhouse gases like methane are released from decomposing organic matter in landfills. It also means reduced demand for agricultural production, easing pressure on land, water, and ecosystems. Efficient use of food conserves natural resources, lowers pollution, and reduces the carbon footprint of food systems, making waste reduction a crucial step in environmental sustainability.
Q5. What can individuals do to help reduce food waste?
Individuals can take meaningful steps to cut down food waste in daily life. Planning meals, making accurate shopping lists, and avoiding impulse buying help reduce excess. Storing food properly in airtight containers or refrigerators keeps it fresh longer. Learning to understand “best before” versus “use by” labels prevents unnecessary discarding. Repurposing leftovers creatively and embracing imperfect produce also minimize waste. Small, mindful changes in households can collectively make a big global difference.
Q6. How do businesses benefit from reducing food waste?
Businesses stand to gain significantly by reducing food waste. Minimizing waste saves costs associated with overproduction, inventory management, and disposal. Companies that adopt sustainable practices also improve efficiency, streamline supply chains, and boost profitability. Additionally, donating surplus food or repurposing waste enhances brand image and fulfills corporate social responsibility goals. Consumers increasingly value sustainability, so businesses that tackle food waste also strengthen their reputation and build customer loyalty in the long run.
Q7. How does this align with the UN Sustainable Development Goals (SDGs)?
Reducing food waste directly supports the United Nations Sustainable Development Goals. Specifically, it advances SDG 2 (Zero Hunger) by redirecting surplus food to those in need and improving global food security. It also contributes to SDG 12 (Responsible Consumption and Production) by encouraging sustainable food practices across industries and households. Indirectly, cutting waste supports SDG 13 (Climate Action) by reducing emissions, creating a more sustainable and resource-efficient global food system.
Conclusion
The International Day of Awareness of Food Loss and Waste reminds us that tackling this issue is not just about saving food—it is about saving lives, resources, and the planet.
