豆类目前在欧洲联盟的产量水平较低，可以通过减少氮肥和提高蛋白质自给率来减少农业系统的负面环境外部效应。与德国不同，这导致法国采用了耦合支持。然而，德国实施的硝酸盐指令对豆类更有利。我们的研究评估了这两项政策对豆类生产的经济和环境影响。我们采用代表法国和德国奶牛场的生物经济模型FarmDyn。结果表明，相对较低水平的配套支持可以导致豆类生产的适度增加，但更大的变化需要相当大的补贴。允许法国农场在豆类作物上施用粪肥，这在德国已经是可能的，这促进了豆类作物的生产，同时大大减少了合成氮肥和进口的富含蛋白质的饲料的使用。然而，环境效益有限。
Legumes, which currently show low production levels in the European Union, can reduce negative environmental externalities of agricultural systems by lowering nitrogen (N) fertilization and increasing protein self-sufficiency. This has led to the introduction of coupled support in France, in contrast to Germany. However, the German implementation of the Nitrates Directive is more favorable for legumes. Our study assesses economic and environmental impacts of these two policies affecting legume production. We employ the bio-economic model FarmDyn, representing French and German dairy farms. The results suggest that relatively low levels of coupled support can lead to modest increases in legume production, but that more substantial changes require considerable subsidies. Allowing the French farm to apply manure on legumes, as is already possible in Germany, fosters legume production while considerably reducing the use of synthetic N fertilizer and imported protein-rich feed. However, environmental benefits are limited.
