Throughout the developed world, food is treated as a disposable commodity. Between a third and half of all food produced for human consumption globally is estimated to be wasted. However, attempts to quantify the actual magnitude of food wasted globally are constrained by limited data, particularly from developing countries. This article attempts to quantify total food waste generation (including both pre-consumer food losses, as well as post-consumer food waste) in South Africa. The estimates are based on available food supply data for South Africa and on estimates of average food waste generation at each step of the food supply chain for sub-Saharan Africa. The preliminary estimate of the magnitude of food waste generation in South Africa is in the order of 9.04 million tonnes per annum. On a per capita basis, overall food waste in South Africa in 2007 is estimated at 177 kg/capita/annum and consumption waste at 7 kg/capita/annum. However, these preliminary figures should be used with caution and are subject to verification through ongoing research.
在发达世界,食物被视为一次性商品。据估计,全球生产的供人类消费的食物中有三分之一到一半被浪费掉了。然而,由于数据有限,特别是来自发展中国家的数据有限,试图量化全球实际浪费的食物量受到限制。本文试图量化南非的食物总浪费量(包括消费前食物损失和消费后食物浪费)。这些估计数是基于南非现有的食物供应数据以及对撒哈拉以南非洲食物供应链每一步骤的平均食物浪费量的估计数。南非食物浪费量的初步估计数约为每年 904 万吨。按人均计算,2007 年南非的总食物浪费估计为每人每年 177 公斤,消费浪费为每人每年 7 公斤。然而,这些初步数字应谨慎使用,并需通过正在进行的研究进行核实。
