摘要

欧盟委员会最近接受了农业生态学的概念,将其作为减少农业食品系统对环境负面影响的途径。到目前为止,尚不清楚如果大规模实施,农业生态学能否实现这些厚望。我们在此评估了2050年欧盟多种农业生态未来的社会经济和环境影响,基于一种新的诊断情景方法,即生物量平衡模型BioBaM GHG 2.0。我们发现,从地块到粮食系统层面的农业生态措施确实可以在保持欧盟国内粮食供应的同时减轻环境压力。例如,这些措施是在农田上增加树篱,或在高自然价值的HNV草原上减少生物量收获。然而,一个关键的先决条件是全面减少粮食系统的规模(基于减少动物生产、食物浪费和出口生产)和优化作物与牲畜的整合。只有这样,欧盟向农业生态农业食品系统的转变才不会有过度扩张国内土地供应或生产不足农产品的风险。缓解随之而来的农业收入减少的权衡是政策制定的核心任务,旨在重新设计欧洲的农业,以符合绿色协议的目标。

Impacts of Scaling up Agroecology on the Sustainability of European Agriculture in 2050 Les impacts du développement de l'agroécologie sur la durabilité de l'agriculture européenne en 2050 Die Auswirkungen einer großflächigen Verbreitung von agrarökologischen Maßnahmen auf die Nachhaltigkeit der europäischen Landwirtschaft im Jahr 2050

The European Commission recently embraced the concept of agroecology as a pathway to reduce negative impacts from agri-food systems on the environment. So far, it remains unclear whether agroecology can deliver on these high hopes if implemented on a large scale. We here assess socio-economic and environmental implications of multiple agroecological futures in the European Union in 2050, based on a novel diagnostic scenario approach, i.e. the biomass balancing model BioBaM-GHG 2.0. We find that agroecological measures from the plot to the food systems level can indeed reduce environmental pressures while maintaining domestic food availability within the EU. Such measures are, for example, more hedgerows on croplands or reduced biomass harvest on high natural value – HNV grasslands. However, a key prerequisite is an overall reduction of the food system's size (based on the reduction of animal production, food wastes, and export production) and an optimised crop-livestock integration. Only then does the transformation towards an agroecological agri-food system in the EU not risk overstretching domestic land availability or produce insufficient agricultural commodities. Mitigating the accompanied trade-off of reduced farm income is a central mandate for policy development aimed at re-designing agriculture in Europe to align with the Green Deal goals.

期刊介绍: EuroChoices is a full colour, peer reviewed, outreach journal of topical European agri-food and rural resource issues, published three times a year in April, August and December. Its main aim is to bring current research and policy deliberations on agri-food and rural resource issues to a wide readership, both technical & non-technical. The need for this is clear - there are great changes afoot in the European and global agri-food industries and rural areas, which are of enormous impact and concern to society. The issues which underlie present deliberations in the policy and private sectors are complex and, until now, normally expressed in impenetrable technical language.
