1. Understanding the Scope of Global Food Waste
Food waste is a significant global problem, impacting economies, the environment, and food security. One-third of all food produced globally is lost or wasted, costing the global economy over $1 trillion annually and contributing to 8-10% of global greenhouse gas emissions. According to the UN Environment Programme, food waste occurs at similar levels in middle-income and high-income countries, indicating that this is a universal issue needing urgent attention. The World Wide Fund For Nature (WWF) also notes that food loss on farms is a problem in high-income countries as well as middle- and lower-income countries.
1.1 What are the main differences between Food Loss and Food Waste?
Food loss refers to the decrease in the quantity or quality of food resulting from decisions and actions by food suppliers in the chain, excluding retailers, food service providers and consumers, while food waste refers to the decrease in the quantity or quality of food resulting from decisions and actions by retailers, food service providers and consumers. Understanding these differences helps in targeting interventions more effectively.
1.2 What are the Primary Causes of Food Loss?
Food loss happens near farms and in the supply chain because of factors like inadequate technology, such as poor infrastructure and lack of cold storage. Inadequate equipment also contributes to food loss, making it hard to harvest crops efficiently. Suboptimal packaging is another factor, as it can affect how long foods stay safe to eat.
1.3 What are the Common Reasons for Food Waste?
Food waste happens at the retail level, in restaurants, and in homes because of reasons like poor food management and consumer behaviors. Insufficient skills in food preparation, inflexible procurement requirements, and failure to forecast demand are examples of poor food management. Consumer behaviors, such as lack of awareness and insufficient education about food storage, also contribute to food waste. Norms and attitudes that normalize wasting food and concerns about eating food past its date labels also play a role.
2. Why Reducing Food Waste Matters: The Global Benefits
Reducing food loss and waste offers substantial benefits for economies, businesses, consumers, human health, and the environment. The UN’s Sustainable Development Goals include halving food waste and reducing food losses by 2030 for good reason.
2.1 How can Reduced Food Waste Improve Global Nutrition and Food Security?
Reducing food loss and waste can significantly contribute to providing a healthy, nutritious diet to the growing global population. Perishable foods with higher nutritional value, such as fruit and vegetables, are particularly prone to loss and waste; more than 40% of produce by weight is lost or wasted worldwide each year. Making sure more of the global food supply is used to feed people is an important way to address hunger and malnutrition.
2.2 What is the Impact of Reducing Greenhouse Gas Emissions?
Reducing food loss and waste is the single-best strategy for reducing emissions and fighting the climate crisis, as highlighted by Project Drawdown. Emissions from food loss and waste result from the energy and inputs used to produce food that’s ultimately not consumed, as well as the methane emitted when food rots in fields or landfills. Methane has over 80 times the warming power of CO2.
2.3 What are the Financial Benefits for Businesses and Consumers?
Reducing consumer food waste by 20%-25% by 2030 could save the world an estimated $120-$300 billion per year. Households can reduce their overall spending on food by consuming more of what they purchase. Eliminating avoidable food waste would save the average family in the United Kingdom more than £700 ($870) each year, while in the United States, the average family would save approximately $1,800. Additionally, reducing food losses, especially post-harvest, will improve farmers’ incomes.
