摘要:

 最近一系列的研究集中讨论气候变化对农产品、陆地利用、污染和生物多样性的影响,意味着气候变化对食品安全的影响已成为广泛关注和研究的焦点。虽然如此,气候变化对消费者的食物和饲料安全影响的专题研究报道仍然很少。通过文献综述,主要围绕气候变化对种植业和畜牧业的影响,分析气候变化对食品安全的各种影响。一般认为,种植业是农业和养殖业中对气候变化反映最为敏感的环节,气候参数如温度、干旱、降雨、风和CO2水平的变化,将改变农业化肥、农药投入,引起土壤退化,加重作物害虫、昆虫和病害受灾程度。气候变化对畜牧业也将产生严重的影响,而且,极端天气如洪水和热浪伴随的食品病原菌污染都对将来的食品安全构成严重威胁。因此,在气候变化背景下人类将面临食品安全的严峻挑战。

Abstract:

A series of recent researchs focuses on the impact of climate change on agricultural production, land use, pollution and biodiversity, which implies the potential impactof climate change on food security is awidely debated and investigated issue. Nonetheless, the specific safety influence of food and feed for consumers has remained a less studied topic. This review identifies the various food safety issues from some literatures about climate change impacts on crop cultivation and livestock systems. According to general consensus, crop cultivation is recognized as a relatively susceptible partof the food and feed production sector thatcould be affected by climate change, variations in climatic parameters such as temperature, drought, precipitation, wind, and CO2levels are projected to have notable consequences on crops in terms of changes in the demand for fertilizer and pesticides, deterioration of the quality of soils,and expanding ranges of crop pests and altered transmission dynamics of insects, pests and plant diseases. Livestock production also could be heavily influenced by climate change, and the presence ofpathogenic bacteria in foods followingmore frequentextremeweather conditions, such as flooding and heatwaves. Therefore the challenges facing food securitywill pose new risks to human under the background of the global climate change.

Key words: climate change, food safety, environmental change
