《Food Policy》| Danyi Qi et al：中国农村有牲畜的家庭的食物浪费减少更多
摘要：发展中国家粮食浪费趋势的持续演变和畜牧业系统的集约化对形成全球可持续发挥了关键作用。我们探索了家庭层面的食物浪费和畜牧业系统之间的联系，以及在20世纪90年代和21世纪初的10年，当市场自由化政策实施之后的导致畜牧业生产集约化时，这种联系是如何发生变化的。我们发现，在这段时间内，所有农村家庭的食物浪费数量显著下降。在90年代初，拥有牲畜的家庭(通常使用未食用的食物作为动物饲料)比其他农村家庭多产生约75%的食物浪费，但在之后20年，食物浪费明显减少，动物蛋白消费量明显增加。我们认为，畜牧业的集约生产使更少的未食用的食物被用作动物饲料，从而导致了更有效的家庭消费。我们反对在畜牧业集约化开始之前家庭牲畜生产和消费决策的可分离性，但认可此后的可分离性。最后，我们将讨论畜牧业集约化对整体粮食系统的可持续性的影响。

Abstract: The ongoing evolution of food waste trends and the intensification of livestock systems in developing economies play a critical role in shaping global sustainability. We explore the linkage between food waste and livestock systems at the household level and how this connection changed in China during the 1990s and 2000s when market liberalization was followed by policies that led to intensification of livestock production. We find the amount of food waste in all rural households declined significantly over this period. Households with livestock, which often use uneaten food for animal feed, created about 75% more food waste than other rural households at the beginning of this period, but experienced significantly greater reductions in food waste and significantly greater increases in animal protein consumption over the study period. We postulate that intensified livestock production led to less uneaten food being used as animal feed and, in response, led to more efficient household consumption including less discarded food. We reject the separability of household livestock production and consumption decisions prior to the onset of livestock intensification, but cannot not reject separability thereafter. We end by discussing the implications of livestock intensification for overall food system sustainability.
