Waste Not, Want Not

Food waste is a significant global challenge – but how food is wasted depends largely on context.   

One third of all food produced is wasted, says a recent report from The Food and Agriculture Organization of the United Nations (FAO). Food is lost at every stage, from initial production, through the supply chain, the retail stage, and finally at the household level.

In developing countries 630 million tonnes of food is lost in agricultural production, mostly due to substantial post-harvest losses caused by inadequate storage facilities and poor marketing and distribution channels. Much less is wasted in household consumption.

In medium and high income countries about 220 million tonnes of food is lost at the household level. This loss is the equivalent of the total net food produced in Sub Saharan Africa. Here in Canada approximately 40 percent of food produced is wasted along the food chain. More than 50 percent of this waste is through consumer behavior – food thrown away in Canadian homes. According to the FAO report, people in high income countries waste food because, financially, they can afford to; perhaps in terms of environmental costs, they cannot.

Wasting food  also means wasting resources used in food production. This means that enormous amounts of resources used in food production are exploited in vain, including the greenhouse gas emissions caused by producing food that is wasted. In a world with limited resources (land, water, energy), and a growing population, cost-effective solutions must be set up to produce enough safe and nourishing food for all. Reducing food losses is a place to start.

From the standpoint of small-scale farmers in developing countries, a simple but strong investment in infrastructure to store and transport food would minimize losses, which world would have an immediate impact on food security, since many small-scale farmers live on the margins of food insecurity. In high income countries food wastage must be curbed through changes in consumer behavior.

Reducing food wastage is a step towards everyone in the world having enough to eat.
