International Day of Awareness of Food Loss and Waste (IDAFLW) - 29 September

第五个国际粮食损失和浪费问题宣传日纪念活动将强调需要加大融资力度，助力减少粮食损失和浪费、促进实现气候目标、推进落实《2030年可持续发展 议程》。

全球粮食产量足以养活世界上的每个人，然而仍有亿万民众深陷饥饿和营养不良状况。粮食损失和浪费减少了可供消费的食物数量，加剧了这一问题，从而导致粮食不安全。许多营养最丰富的食物，如新鲜农产品、水产品和动物产品，极易变质，导致损失水平较高。

粮食损失和浪费造成巨大的经济损失，不仅影响生产者，还影响消费者和国家，更不用说生计和经济稳定了。此外，被送往垃圾填埋场处理的食物占农业粮食体系温室气体排放量的8-10%，影响气候变化和环境可持续性。

Food loss and waste in numbers

• An estimated 13% of food produced is lost globally after harvest and prior to reaching retail shelves based on the most recent estimates ( FAO, 2019).

• Recently updated estimates showed that a frightening 19% of food available to consumers – the equivalent of 1.05 billion tonnes – is wasted either by being discarded at retail, in food service settings, or thrown away by households. That’s almost one fifth of all food that reaches the end of the supply chain ( UNEP, 2024).

• Collectively, we waste a lot of food at home. In fact, a staggering 60% of food waste is wasted at the household level, 28% from food service, and 12% from retail ( UNEP, 2024).

• While all this food is being lost and wasted, an estimated one in thirteen people worldwide experienced hunger in 2025, representing between 608 and 696 million people (7.4-8.5 percent of the global population). Moreover, an estimated 2.1 billion people - 25.8 percent of the global population - experienced moderate or severe food insecurity ( FAO, 2026).

• According to the latest estimates, approximately 2.69 billion (32.7 percent) people in the world cannot afford a healthy diet ( FAO, 2026). Among the various food groups, fruits and vegetables - a key component of a nutritious diet - experience the highest percentage of losses, further aggravating this global challenge ( FAO, 2019).

• Food loss and waste also contributes to 10% of global greenhouse gas emissions (FAOSTAT, 2025), impacting climate change and environmental sustainability. Reducing food loss and waste is therefore a climate solution, which countries and communities can employ to reduce greenhouse gas emissions and protect natural resources ( IPCC, 2019).

• Food that is never eaten uses up 28% of the world’s agricultural land area ( FAO, 2013).

• The global land occupation footprint of food loss and waste, which is the total hectares used to grow food that ends up not being consumed, is about 1.4 billion hectares ( FAO, 2013), which is larger than Canada or China.

• Food loss is also a market failure, representing an estimated annual loss of US$400 billion in food value ( FAO, 2019).

• Food waste results in the throwing away of more than US$1 trillion worth of food every year ( UNEP, 2024).
