On 29th September, the world celebrates the International Day of Awareness of Food Loss and Waste. This day serves as a global call to reflect on the alarming amount of food that is lost and wasted along the production and consumption chain. Approximately one-fifth of the food produced worldwide is lost or wasted before it reaches the table, which equates to about one billion meals lost daily.
The impact of this waste is profound, not only on the environment but also in the fight against hunger. In the current context, the world produces enough food to feed everyone, yet, according to the latest State of Food Security and Nutrition in the World (SOFI) report, around 733 million people are hungry.
Food waste, especially in developing countries, is often a result of inadequate infrastructure and technology for the storage, processing, and transportation of crops. In wealthier countries, waste primarily occurs in kitchens, where food is discarded after passing its expiry date or being forgotten on shelves.
In this scenario, the World Food Programme (WFP) Centre of Excellence against Hunger in Brazil highlights one of the most effective initiatives in combating food waste and promoting food security: the National School Feeding Programme (PNAE). In some schools, PNAE utilises locally sourced food from farmers to provide healthy meals. This approach not only reduces waste but also strengthens family farming and ensures that food reaches those who need it most – school-aged children.
The local purchasing promoted by PNAE not only reduces post-harvest losses but also supports small farmers, who often struggle to access markets and store their crops properly. The programme contributes to the creation of a sustainable supply chain, where food is consumed within the community where it is produced, minimising environmental impact and strengthening the local economy.
Furthermore, PNAE is a practical example of how integrated solutions can address the causes of hunger and waste. By connecting local production with consumption in schools, the programme not only improves children’s nutrition but also helps reduce greenhouse gas emissions, as fewer food items are transported over long distances and fewer resources are wasted along the production chain.
The International Day of Awareness of Food Loss and Waste serves as a reminder that everyone – governments, organisations, and individuals – has a role to play in reducing waste and ensuring that natural resources – such as land, water, and energy – are used efficiently. The Centre of Excellence against Hunger and PNAE are clear examples of how concrete actions can transform this reality and build a more sustainable and just future for all.
