WWF examines on-farm crop losses
The World Wildlife Fund has released a report measuring on-farm crop waste at various locations in the United States. During the 2017-18 growing season, 40% of tomatoes, 39% of peaches, 2% of potatoes and 56% of romaine lettuce were left in the field. Causes of waste at the farm stage include strict quality standards, damage due to weather, variable consumption patterns and unpredictable labour supply. Some growers pointed out, however, that the nutrients in on-farm waste food are almost always recycled, e.g. as animal feed or by ploughing the waste back into the field.
North America is the northern subcontinent of the Americas covering about 16.5% of the Earth's land area. This large continent has a range of climates spanning Greenland’s permanent ice sheet and the dry deserts of Arizona. Both Canada and the USA are major food producers and some of the largest food exporters in the world. Industrial farms are the norm in North America, with high yields relative to other regions and only 2% of the population involved in agriculture.
