摘要
麦吉尔大学和明尼苏达大学发表在《自然》杂志上的一项新研究比较了66项研究和316项试验的有机和传统产量(Seufert et al. 2012)。研究人员发现,有机系统的平均产量比传统的化学密集型系统低25%,尽管这是高度可变的和具体的环境。接受当前的传统智慧,作者主张将传统农业和有机农业结合起来,以满足“养活不断增长的人口的双重挑战,对肉类和高热量饮食的需求不断增加,同时最大限度地减少其对全球环境的影响”(Seufert et al. 2012, 3)。不幸的是,这项研究和传统智慧都没有解决饥饿的真正原因。饥饿是由贫穷和不平等造成的,而不是由匮乏造成的。在过去的二十年里,全球粮食产量的增长速度超过了全球人口的增长速度。根据联合国粮食和农业组织(2009a, 2009b),世界生产的粮食是地球上每个人的1 /2多倍。这已经足够养活100亿人了,这是2050年预计的世界人口峰值。但是,那些每天收入低于2美元的人——其中大多数是资源贫乏的农民,耕种着不适合生存的小块土地——买不起这种食物。实际上,大部分工业化生产的粮食作物(研究中发现减产的主要是谷物)被用于生物燃料和封闭的动物饲养场,而不是为10亿饥饿人口提供食物。到2050年粮食产量翻一番的呼吁只有在我们继续优先考虑不断增长的牲畜和汽车人口而不是饥饿人口的情况下才适用。实际上,这项新研究告诉我们的是,有机农业和传统农业之间的产量差距比有机农业的批评者所假设的要小得多。Smil(2001)声称有机农业需要两倍的土地基础,这已经成为一个传统的口头禅。事实上,当我们打开《自然》杂志研究的数据时,我们发现,对于许多作物,在许多情况下,报告的产量差距是很小的。随着有机系统种子育种的新进展,以及商业化的过渡
We Already Grow Enough Food for 10 Billion People … and Still Can't End Hunger
A new a study from McGill University and the University of Minnesota published in the journal Nature compared organic and conventional yields from 66 studies and 316 trials (Seufert et al. 2012). Researchers found that organic systems on average yielded 25% less than conventional, chemical-intensive systems—although this was highly variable and context specific. Embracing the current conventional wisdom, authors argue for a combination of conventional and organic farming to meet “the twin challenge of feeding a growing population, with rising demand for meat and high-calorie diets, while simultaneously minimizing its global environmental impacts” (Seufert et al. 2012, 3). Unfortunately, neither the study nor the conventional wisdom addresses the real cause of hunger. Hunger is caused by poverty and inequality, not scarcity. For the past two decades, the rate of global food production has increased faster than the rate of global population growth. According to the Food and Agriculture Organization of the United Nations (2009a, 2009b) the world produces more than 1 /2 times enough food to feed everyone on the planet. That’s already enough to feed 10 billion people, the world’s 2050 projected population peak. But the people making less than $2 a day—most of whom are resource-poor farmers cultivating un-viably small plots of land—cannot afford to buy this food. In reality, the bulk of industrially produced grain crops (most yield reduction in the study was found in grains) goes to biofuels and confined animal feedlots rather than food for the one billion hungry. The call to double food production by 2050 only applies if we continue to prioritize the growing population of livestock and automobiles over hungry people. Actually, what this new study does tell us is how much smaller the yield gap is between organic and conventional farming than what critics of organic agriculture have assumed. Smil’s (2001) claim that organic farming requires twice the land base has become a conventional mantra. In fact, when we unpack the data from the Nature study, we find that for many crops and in many instances, the reported yield gap is minimal.
