Abstract

Organic farming has gained attention as a sustainable form of agriculture. However, concerns have been raised about its relatively low productivity. This paper reviews 23 modeling studies devoted to the large-scale implementation of organic farming that explicitly consider food supply and demand, with a particular focus on the capability of the simulated systems to provide sufficient food. Across all studies, the expansion of organic farming resulted in an important decrease in food production, which was more pronounced in studies simulating N cycle and its effects on organic crop yields (−44%). Nonetheless, this decrease could be compensated for by dietary changes and by a combination of other complementary measures. These results are nuanced by knowledge gaps and limitations of current models, particularly regarding the simulation of organic systems productivity and the consideration of outcomes beyond food provisioning. This review adds weight to the recent calls for a food system approach and contributes to future research on the implementation of agroecological systems and global food security modeling.

有机农业的扩展与粮食安全:展望模型研究综述
有机耕作作为一种可持续的农业形式,已受到人们的关注。然而,人们对其相对较低的生产率表示担忧。本文回顾了 23 项关于大规模实施有机农业的建模研究,这些研究明确考虑了粮食供需问题,尤其关注模拟系统提供充足粮食的能力。在所有研究中,有机农业的扩大导致粮食产量大幅下降,这在模拟氮循环及其对有机作物产量影响的研究中更为明显(-44%)。不过,这种减少可以通过改变饮食习惯和综合采取其他辅助措施来弥补。这些结果因知识差距和当前模型的局限性而变得微妙,特别是在模拟有机系统生产力和考虑粮食供应以外的结果方面。这篇综述为最近关于采用粮食系统方法的呼吁增添了分量,并有助于未来关于实施生态农业系统和全球粮食安全建模的研究。

期刊介绍: Global Food Security plays a vital role in addressing food security challenges from local to global levels. To secure food systems, it emphasizes multifaceted actions considering technological, biophysical, institutional, economic, social, and political factors. The goal is to foster food systems that meet nutritional needs, preserve the environment, support livelihoods, tackle climate change, and diminish inequalities. This journal serves as a platform for researchers, policymakers, and practitioners to access and engage with recent, diverse research and perspectives on achieving sustainable food security globally. It aspires to be an internationally recognized resource presenting cutting-edge insights in an accessible manner to a broad audience.
