The environmental impacts of agriculture have been a major concern among the agricultural and environmental scientific communities. The expansion of agriculture is thought to have resulted in loss of biodiversity, loss of habitat and adverse impact on soil condition. The intensification of agriculture may contribute to environmental pollution by chemical fertilizers and pesticides, degradation of water, and increased energy use. As an example since the 1960s, human use of synthetic nitrogen fertilizer has increased 9 fold, globally, while demand for phosphorus fertilizers has tripled. Therefore, meeting the world’s future food security needs, while making progress towards reducing the adverse environmental impacts of agriculture is a global challenge.

农业对环境的影响一直是农业和环境科学界关注的一个主要问题。据认为，农业的扩张导致了生物多样性的丧失、生境的丧失和对土壤状况的不利影响。农业的集约化可能会导致化肥和杀虫剂造成的环境污染、水的退化和能源使用的增加。例如，自20世纪60年代以来，全球人类对合成氮肥的使用量增加了9倍，而对磷肥的需求增加了两倍。因此，满足世界未来的粮食安全需求，同时在减少农业对环境的不利影响方面取得进展，是一项全球性挑战。
