In recent years climate change and its impacts have become a separate field of inquiry. Climate-related risks to food security, water supply, biodiversity and human health are expected to increase with further global warming. The purpose of this study is to show how the definition of food security in particular has changed in times of climate change. It is a multidimensional phenomenon that has no legal definition so far. Associated mainly with physical access to food, food security was identified as a global problem by Food and Agriculture Organization (FAO) in 1975 at the Word Food Conference. At the European Union level, food security is strictly connected with the Common Agriculture Policy. One of the new aims of that policy is to make agriculture more sustainable and responsive to current and future challenges, including climate variability. There is the dual challenge of both adapting production systems to new conditions and reducing greenhouse gases produced by agriculture.

近年来，气候变化及其影响已成为一个单独的研究领域。随着全球进一步变暖，粮食安全、供水、生物多样性和人类健康面临的气候相关风险预计将增加。本研究的目的是展示粮食安全的定义在气候变化时期是如何变化的。这是一种多维现象，目前还没有法律定义。粮食安全主要与实际获得食物有关，粮食安全被粮食及农业组织（FAO）确定为一个全球性问题) 于 1975 年在世界食品大会上。在欧盟层面，粮食安全与共同农业政策密切相关。该政策的新目标之一是使农业更具可持续性并能应对当前和未来的挑战，包括气候变异。使生产系统适应新条件和减少农业产生的温室气体是双重挑战。
