The herriza stands out by its high plant biodiversity and profuse flowering that supports a wide range of insect pollinators. Yet, the herriza has been heavily afforested with pine trees until the onset of the 21st century. This past activity provides a unique natural experiment to assess the effect of afforestation on flower abundance and associated pollinator diversity. We conducted a two-year field study of the diversity and abundance of flowers and pollinators in five selected sites, each consisting of two adjacent plots of open and afforested herriza. Afforested herriza plots had consistently lower diversity and abundance of flowers and insect pollinators than open herriza plots. Our results highlight the negative impact of afforestation of a treeless habitat on its flowering pattern and associated insect pollinator guilds. We thus suggest seeking alternatives to afforesting naturally treeless habitats in order to avoid conflicts between carbon sequestration and pollinator conservation.

We integrated information on pressures and habitats/species with the measures to identify non-spatial management gaps. Then, we integrated the spatially explicit information to determine the spatial management gap, identifying geographical areas where species/habitats are under pressure without registered measures. We demonstrated the importance of integrating existing information. Our findings revealed that resources were often not distributed adequately across species/habitats, with biases towards certain taxa being a common issue. The non-spatial management gap analysis identified taxonomic groups, especially plants and mollusks with the wider management gaps. We also identified threatened areas, especially in the northeast of the region with the larger spatial management gaps. These results could guide priority objectives to optimize conservation efforts. Integrating different information sources provided a broader view of the challenges that conservation science is facing nowadays. Our study offers a path toward bending the curve of biodiversity loss by providing an integrative framework that could optimize the use of the available information and help narrow the knowing-doing gap. In the context of the EU, this example demonstrates how information can be used to promote some environmental policy instruments, such as the Prioritized Action Frameworks (PAFs). Additionally, our findings highlight the importance of supporting decision-making with systematic assessments to identify deficiencies in the conservation process, reduce the loss of critical ecosystems and species, and avoid biases among taxa.

It emerges that, while many CC-BIO-CE interlinkages have been addressed, others that may be critical to meeting the EGD goals still need to be fully understood and managed. Among trade-offs, a special attention should be paid to the planned use of the maritime space according to different objectives that seem difficult to reconcile, the ‘substitution process’ triggered by the large-scale deployment of zero-emission vehicles, and the potential effects on biodiversity of the increasing use of biomaterials. With regard to synergies, the CE-BIO connection may be strengthened through a stricter focus of the CE concept on how resources are extracted (which could include the implementation of regenerative practices). Moreover, in order to truly incorporate CE into CC policy, the real impact of the former on GHG emissions should be better demonstrated and measured.

The actions tracker is specifically designed to track progress on the implementation of the more than a hundred actions stemming from the EU BDS, while the dashboard monitors progress across 16 targets using indicators. However, while the actions tracker is a mature tool, the work on the dashboard is still in progress, as indicators are missing for several targets. New scientific input is needed to propel policy tracking and ensure transparent and data-driven monitoring of the EU BDS targets. With this paper, we invite the scientific community to seize this opportunity to actively participate in the policy monitoring process

We weighted single indicator values with countrywise modeled data on changed timber production under EUBDS implementation. Nearly 80% of the indicators pointed to higher vulnerability in the affected non-EU countries. Roundwood production was transferred to countries with, on average, lower governance quality (p = 0.0001), political awareness (p = 0.548), forest coverage (p = 0.034), and biomass (p = 0.272) and with less sustainable forest management (p = 0.044 and p = 0.028). These countries had more natural habitats (p = 0.039) and intact forest landscapes (p = 0.0001) but higher risk of species extinction (p = 0.006) and less protected area (p = 0.0001) than the EU countries. Only a few indicators pointed to lower vulnerability and biodiversity risks outside the EU. Safeguards are needed to ensure that implementation of EUBDS does not cause harm to ecosystems elsewhere. The EU regulation on deforestation-free supply chains might have limited effects because the sustainable management of existing and even expanding forests is not well considered. Sustained roundwood production in the EU is needed to avoid placing more pressure on more vulnerable ecosystems elsewhere. Decreasing species and habitat indicator values nevertheless call for global conservation and protection schemes. The EUBDS helped pave the way to the Kunming-Montreal Biodiversity Framework. Yet, lower values for the indicators mean governance and biodiversity engagement in non-EU countries suggest that this global framework might not sufficiently prevent leakage of risks to biodiversity. Effective land-use planning is necessary to balance conservation schemes with roundwood production.

Triazines, phenylureas, and organophosphates were the predominant pesticide classes, with terbuthylazine, bentazone, terbutryn, diazinon, and metolachlor exhibiting the highest detection frequencies (68 % to 72 %). Notably, 44 % of the quantified pesticides are no longer authorized in Portugal, with 33 % posing a high environmental risk. Some insecticides, including imidacloprid, methiocarb, and malathion, were occasionally detected at concentrations that posed high risks to the aquatic ecosystem (RQ ≥ 1). Irgarol, an algicide used in irrigation canals, presented a high risk in 91 % of the analysed samples. The study's distribution profile of pesticides revealed a significant transportation of these compounds from reservoirs to irrigation hydrants, establishing them as a secondary source of crop and environmental contamination. Additionally, the assessment of spatial distribution and environmental risk allowed for the identification of specific pollutants in different locations, prioritizing them based on their ecotoxicological risk to aquatic ecosystems. These findings reinforce the importance of implementing management measures at the level of hydro-agricultural areas, helping to stop the cycle of pesticide contamination. Only this type of strategy will make it possible to protect water quality, biodiversity and the health of citizens, contributing to the European Union's objectives of improving the condition of freshwater bodies and promoting the sustainable use of pesticides.

In a dynamic perspective, it analyses the effect, if any, on national conservation policy. Due to the characteristics of the indicator chosen, which is stock-sensitive and subject to saturation effect, it verifies whether the relationship between income level and PA% is still an EKC, or whether a convergence in conservation policy has emerged and PA% is tending to a steady state. This is done by running regression models on the countries to test said EKC and β-convergence hypotheses. The results confute the persistence of an EKC and show a convergence in conservation policy in the last two decades, albeit with interesting differences between groups of countries, in particular latecomers as opposed to old member states of the EU. The results have important policy implications: when dealing with public or collective goods, or goods that produce externalities, centralised (federal) guidance is more effective than local and decentralised approaches (subsidiarity principle)

The ecoregion-based approach and the findings of this study can inform initiatives under the EU Biodiversity Strategy to 2030, in particular the target to ‘strictly protect’ 10% of the EU’s land and sea.

Both the YRD and France experienced a shift in the declined SNHs towards higher altitudes. There was noticeable landscape fragmentation and degraded ecosystem services in the hilly areas of YRD and the high plains of France. The agricultural policies of the EU achieved limited success in protecting SNHs, while China's agricultural landscapes were rapidly losing SNHs due to the absence of policy support. Based on these, the paper puts forward some countermeasures and suggestions for developing SNHs in China and the EU. Our study contributes to the global effort for agroecological conservation.

The findings revealed that policy entrepreneurs were able to align the three streams by financing studies and workshops (problem stream), adopting an existing successful policy (policy stream) and leveraging an existing close political relationship in the EU (politics stream) as well as overcoming issues raised by other parties through further analysis and studies showing the benefit of the ECA policy for all Mediterranean countries (linking the problem and policy streams). The study also highlighted the importance of first achieving regional agreement before approaching the IMO global level, a lesson that may also be pertinent to other areas of maritime policy making.

Despite the potentially positive symbolic effect in mobilizing a global agenda for combating deforestation, the EUDR faces several drawbacks and risks associated with three of its constitutive features: To be demand-oriented, having the value chain as the unit of intervention and holding a high degree of unilateralism. We conclude that to be effective in curbing tropical deforestation, the Regulation must be complemented with international cooperation aiming to strengthen national policies with a territorial approach, as well as social movements addressing the underlying causes of forest loss and human rights violations in the territories where it takes place.
