Abandoned farmland: Past failures or future opportunities for Europe's Green Deal? A Baltic case-study

Competing societal demands on land require careful land management. In the era of the European Green Deal, farmers are required to meet some of these competing demands, specifically around production, greenhouse gas emission reductions, and biodiversity conservation. At the same time, 15.1% of total EU land is abandoned or underutilised, which means that it contributes neither to food, nor to ecosystem services, to its full potential. Reintegrating abandoned agricultural land back into production is therefore one of the potential pathways to deliver on the aspirations of the Common Agriculture Policy post-2020. In this paper we assess the potential of managing and reintegrating abandoned agricultural land in Europe to simultaneously increase primary productivity, carbon regulation and habitat for biodiversity, using Latvia as a national case-study that is representative of this challenge in a Baltic context. Our results show that for some regions, reintegration of abandoned agricultural land can lead to triple win synergies. These opportunities can be further exploited by applying best management practices to these reintegrated lands. In other regions, where the area of abandoned agricultural land is limited because of favourable biophysical conditions for intensive agricultural production, such triplewin synergies are scarce. In such areas, abandoned land plays a role in maintaining ecosystem services at local and regional scales, and even small increases in primary productivity come at the expense of biodiversity. This calls for careful management that involves diverse actor groups, including land managers, in the decision-making process, and in priority setting in each of the regions.

Automated summary

The management and reintegration of abandoned agricultural land in Europe can lead to triple win synergies in terms of increasing primary productivity, carbon regulation, and biodiversity habitat. However, in regions where abandoned agricultural land is limited due to favorable conditions for intensive agricultural production, such synergies are scarce. Abandoned land plays a crucial role in maintaining ecosystem services and biodiversity, and even small increases in primary productivity come at the expense of biodiversity. Therefore, careful management involving diverse actors is necessary in decision-making and priority setting in each region.
