=== 7.3.1 What is at stake for food security? ===

<div id="section-7-3-1-what-is-at-stake-for-food-security-block-1"></div>

This section examines risks to food security when access to food is jeopardised by yield shortfall and instability related to climate stressors. Past assessments of climate change impacts have sometimes assumed that, when grain and food yields in one area of the world are lower than expected, world trade can redistribute food adequately to ensure food security. There is ''medium confidence'' that severe and spatially extensive climatic stressors pose high risk to stability of and access to food for large numbers of people across the world.

The 2007–2008, and 2010–2011 droughts in several regions of the world resulted in crop yield decline that in turn led some governments to protect their domestic grain supplies rather than engaging in free trade to offset food shortfalls in other areas of the world. These responses cascaded and strongly affected regional and global food prices. Simultaneous crop yield impacts combined with trade impacts have proven to play a larger and more pervasive role in global food crises than previously thought (Sternberg 2012 <sup>[[#fn:r1620|1620]]</sup> , 2017 <sup>[[#fn:r1621|1621]]</sup> ; Bellemare 2015 <sup>[[#fn:r212|212]]</sup> ; Chatzopoulos et al. 2019 <sup>[[#fn:r213|213]]</sup> ). There is ''high confidence'' that regional climate extremes already have significant negative domestic and international economic impacts (Chatzopoulos et al. 2019 <sup>[[#fn:r214|214]]</sup> ).
