EKLIPSE is inviting scientists, policy makers, practitioners and other societal actors to share their knowledge on the effects of CAP greening measures on biodiversity and related ecosystem services. A literature screening exercise was done prior to the selection of the request and resulted in a compilation of research papers and reports related to the topic. We invite you to add any information that you think is relevant for the request, and justify its inclusion e.g. additional information from countries, scales or disciplinary perspectives not covered sufficiently etc…). Relevant information should be grouped under the following threads: literature reviews, empirical studies/practical experiences, modelling studies and conceptual papers. The full Call for Knowledge can be downloaded here

Please note of an ongoing survey, asking for inputs to a rapid evidence assessment regarding the impacts of the CAP on the economy, society and the environment. If you wish to participate, please see the link here

We studied the relation between the area of landscape elements and biodiversity (species richness). Knowing this relation we can discuss the percentage of ecological focus area in the landscape we need for greening the CAP. For example in areas with 3% nature elements 52% of all dutch butterfly species are present. In areas with 7% nature elements 64% of all Dutch species is present. For birds these numbers are 66% and 74%. See: Cormont, A., H. Siepel, J. Clement, T.C.P. Melman, M.F. Wallis de Vries, C.A.M. van Turnhout, L.B. Sparrius, M. Reemer, J.C. Biesmeijer, F.

We monitored crop and farmland bird diversity on 178 farms across Sweden’s main agricultural areas. From a pre-implementation assessment, we show that >97% of the assessed farms would not be required to change their management under the CAP crop diversification measure (minimum of three crops for farms with 30+ ha), suggesting that this measure has generated little change on Swedish farms. We also show that crop structural diversity (i.e. the management and vegetation structure of crops) rather than crop diversity senso lato positively affected richness of non-crop breeding bird species with stronger effects in arable, compared with forest-dominated landscapes. No such effects were observed among field-nesting farmland bird species.

We looked into effects of management intensity in permanent grasslands (a CAP greening measure) on various aspects of diversity. These studies highlight that conservation measures focusing on permanent grasslands need to address management intensity to avoid biodiversity losses.

We further documented that these biodiversity losses will impact multifunctionality in permanent grasslands.

We are currently reviewing the literature for available evidence on the greening measures. Most studies we find have evaluated the policy design and implementation by farmers, compared to knowledge on what interventions should be most effective.

"current EFA rules and conventional farming practices it is unlikely that most nitrogen-fixing crops and catch and cover crops grown on EFAs provide significant benefits for farmland biodiversity. In contrast, the EFA options of land lying fallow, hedges, and field margins generally have the potential under typical management to provide much greater, more diverse and more reliable biodiversity benefits. The biodiversity benefits of EFA productive options and fallow could be considerably increased through changes in the incentives and implementation rules."

I, together with Guy Beaufoy have looked at the relationship between semi natural grassland management and butterflies . I can send you a link to the oaper. We also have unpublished case studies related to this work. The Reports by the EEA analysing the Article 17 Reports from EU MS , under the EU Habitats Directive also include extensive anaysis of the effect of agro ecosystems on biodiversity . THe EU Mid Term Review of the EU Biodiversity Strategy (and the associated EU Staff Working Ppaer) also contain relevant analysis of the effects of agriculture and farming practices on biodiversity. These analyses are based on field monitoring data.

For the record, and in case of interest, my current project (3.2017-6.2019) will focus on evaluating the CAP's greening measures. The project's title is:
"Towards the next reform of the EU’s Common Agricultural Policy: evaluating the new greening measures from Ecological and Socio-economic perspectives".
2 Project summary
Agricultural intensification and expansion, combined with abandonment of extensively managed farmland, are leading to ongoing losses of biodiversity (BD) and ecosystem services (ESS). At the same time, rural employment is declining and farmers are facing major economic uncertainties. The EU’s Common Agricultural Policy (CAP) is a key factor shaping these processes but also offering tools to mitigate them. The latest CAP reform has introduced three new “greening measures” into the direct payments to farmers, potentially improving the protection of BD and ESS. However, concerns have been raised that BD, ESS and rural employment are still declining, while farmers situation did not improve.
Toward the next CAP reform, we will conduct an interdisciplinary evaluation of the CAP from both ecological and economic perspectives. Starting with the greening measure “Ecological Focus Areas”, we will inspect how the CAP affects BD, ESS and the links between them. Expanding to all greening measures, we will assess the impacts on land-use, BD (status and trends of birds and butterflies) and ESS, as well as farm structures, farmers’ employment and income. Finally we will assess the ecological effectiveness and cost-effectiveness of different environmental instruments in the CAP, as well as synergies and trade-offs among them and with other instruments. Thereby, we will develop a set of policy recommendations for the next CAP reform.
