Background
According to UN Climate Change News, on September 30, 2024, it was reported that in 2022, 1.05 billion tons of food that was fit for human consumption were wasted or lost throughout the food supply chain. At the same time, 783 million people went hungry, and one-third of the global population faced daily food insecurity. The food that ended up in landfills could have nourished approximately 3 billion people, highlighting significant inefficiencies in the global food system. This situation is unacceptable, and we must do better.
Beyond the statistics, food waste has far-reaching environmental, economic, and social consequences. It accounts for around 25% of annual greenhouse gas emissions, making it the third-largest emitter after China and the U.S. This underscores the urgent need for effective strategies to tackle food waste as a significant contributor to climate change.

Food waste occurs at different stages in the supply chain, varying between developing and developed countries. In developing countries, 40% of food waste happens during post-harvest and processing due to inadequate infrastructure, limited technology, and poor storage facilities. Conversely, in developed countries, 40% of waste occurs at the retail and consumer levels. These differences highlight the need for tailored solutions based on regional challenges and capabilities.
At the retail stage, a significant amount of food is discarded for aesthetic reasons, reflecting consumer perceptions and market standards. In the U.S., over 50% of produce is thrown away for being "too ugly," leading to about 60 million tons of wasted fruits and vegetables annually. This practice exacerbates food waste and highlights society's cultural bias favouring appearance over nutritional value. The waste leads to lost economic opportunities for farmers and retailers. Consumers need to understand that imperfect produce still has the same nutrients. Policies like selling "ugly" produce at a discount could help reduce waste, and society's attitudes towards food must shift.
Understanding Food Waste
Food waste refers to any food that is discarded, lost, or uneaten. It occurs at various stages of the food supply chain, from farmers growing crops, processing, to retail and consumption. In fact, it is estimated that approximately one-third of all food produced globally is wasted.
This statistic underscores the urgent need for action. Food waste is ethically irresponsible and contributes to greenhouse gas emissions in landfills, wasting food and the resources like water, labour, and energy used in its production.
Food Waste in South Africa
In South Africa, 10 million tonnes of food are wasted annually, a third of its 31 million tonnes produced. Hunger has risen since 2014, with 828 million people affected globally in 2021. The Food and Agriculture Organisation (FAO), based in Rome, reports 1.6 billion tons of food wasted globally each year, with 1.3 billion tons being edible. About 13% of food is lost between harvest and retail, and 17% is wasted in households, food services, and retail. The UN General Assembly has designated 29 September as the International Day of Awareness of Food Loss and Waste (IDAFLW), encouraging actions to reduce food loss and waste, enhance food security, create sustainable food systems, and reduce greenhouse gas emissions.
How to Reduce Food Waste and Promote Sustainability
In today's world, the issue of food waste has become increasingly pressing, with significant implications for both the environment and society. Reducing food waste is not merely a personal choice; it is a collective responsibility that can lead to substantial benefits for sustainability. Here are several effective strategies to minimise food waste and promote a more sustainable lifestyle.
Practical Tips for Reducing Food Waste
1. Meal Planning
One of the most effective ways to reduce food waste is through careful meal planning. By taking the time to plan meals for the week, individuals can create a shopping list that reflects only the ingredients needed for those meals. This practice not only helps avoid impulse buying but also ensures that perishable items are used before they spoil.
Make sure to eat before heading to the store to prevent impulse purchases.
2. Smart Shopping
When grocery shopping, it is essential to be mindful of the quantities purchased. Buying in bulk may seem economical, but it can lead to excess food that may not be consumed in time. Opting for smaller quantities of fresh produce and perishable items can help prevent waste. Additionally, checking expiration dates and choosing items that are close to their sell-by dates can also be a smart strategy. Purchase imperfect produce to reduce food waste and cut costs.
Refrain from purchasing sale items in bulk and only buy what is necessary. Remember to buy local produce as far as possible.
3. Proper Food Storage
Understanding how to store food properly can significantly extend its shelf life. For instance, certain fruits and vegetables should be kept in the refrigerator while others fare better at room temperature. To extend their shelf life, freeze your fruits when they begin to spoil. Using airtight containers can help preserve leftovers, and labelling items with dates can remind individuals to consume them before they spoil. Organising your refrigerator to prioritise older items helps avoid spoilage.
4. Serving and Cooking Tips
Using a smaller plate helps control portion sizes by creating an optical illusion that makes portions look larger, promoting satisfaction with less food and healthier eating habits. It also reduces the temptation to overfill your plate, preventing overeating. Preparing meals in smaller quantities prevents waste, saves money, and allows frequent use of fresh ingredients, encouraging dietary variety and efficient ingredient use. Applying the "first in, first out" principle by using older food items before newer ones reduces waste and maximises your grocery budget. These strategies collectively promote a sustainable lifestyle, minimising waste and fostering healthier eating habits.
5. Creative Use of Leftovers
Leftovers are often a source of waste, but with a little creativity, they can be transformed into new meals. For example, leftover vegetables can be added to soups or stews, while stale bread can be repurposed into croutons or breadcrumbs. Embracing the idea of "cooking creatively" can help minimise waste and add variety to meals.
Community Initiatives and Education
In addition to individual efforts, community projects can play a crucial role in significantly reducing food waste. Local organisations and governments can implement programs that promote food recovery, such as food banks and donation drives. Educating the public about the importance of reducing food waste and providing resources for sustainable practices can foster a culture of mindfulness regarding food consumption.
Conclusion: A Collective Effort for a Sustainable Future
Reducing food waste is not just about individual actions; it requires a collective effort from consumers, businesses, and governments alike. By embracing sustainable practices and making conscious choices, we can significantly reduce food waste, alleviate hunger, and contribute to a healthier planet.
Don't forget the significance of composting food items like vegetables, fruits, including their peels and trimmings, along with eggshells and meat. Wasting food also means wasting the energy and water used in its cultivation, harvesting, transportation, and packaging. If food ends up in a landfill and decomposes, it generates methane—a greenhouse gas that is even more potent than carbon dioxide.
Our country needs the establishment of food banks and soup kitchens, supported by contributions from individuals, retailers, and the government. As we move forward, it is essential to recognise the impact of our actions and strive for a future where food is valued and cherished, rather than wasted.
