Highlights • Forest ecosystem service (FES) supply varies a lot due to climatic-ecological reasons. • Mountain and central European forests are hotspots of up to 4 FES simultaneously. • Wood, climate regulation, recreation are moderately to strongly positively related. • Central EU hosts a "wood & water" bundle, Southern EU a "rural-recreational" bundle. • Bundle and administrative maps inform on the complementarity of countries' FES. ; Forests cover about 40 % of the European Union (EU), providing a wide spectrum of invaluable ecosystem services to more than half a billion people. In order to protect and harness this crucial asset, EU policies are advancing multifunctional management. This study lays a basis for such an effort by mapping the supply of key forest ecosystem services (FES) across the entire EU: wood, water supply, erosion control, pollination, habitat protection, soil formation, climate regulation and recreation. To further support the operationalization of multifunctionality and targeting of policies, our analysis delineates hotspots, assesses synergies and tradeoffs, and identifies spatial bundles. We generated maps at 1-km resolution starting from existing datasets through simple modelling (Tier 1). Out of these maps, we denoted the highest supplying pixels (i.e. top 20 %) as hotspots, and performed correlation analysis to detect synergies and tradeoffs. Finally, we used cluster analysis to identify FES bundles. Our analysis shows that hotspots of single FES are spread across the entire EU and that forests of mountain regions and Central Europe (particularly France, Germany, Slovakia) supply significant amounts of multiple FES. The cluster analysis resulted in four bundles: "balanced" in the northeast, "wood & water" in the center, "soil carbon" in the north and "rural-recreational" in the south. While a purely quantitative analysis of the produced maps may be misleading because of the strong links between FES supply and climatic and socio-economic conditions, overlaying hotspots and bundles with administrative layers can be a first step to inform about the role of different countries and regions in securing the sustainable supply of European FES.

The temporal trajectory of ecosystem services (ES) is often driven by changes in land use and management caused by human activities. Land intensification has been a major reason for changes in land use and management in the last decades, resulting in increases in agricultural yields and decreases in biodiversity and most ES. Previous research and models have dealt with how biodiversity declines with land intensification but knowledge is scarce on the impacts of land intensification on ES. In this paper, we explore how changes in land-use intensity influences the production of bundles of ES, using mountain landscapes as examples. We review case studies of ES dynamics in mountain landscapes and combined concepts from existing frameworks to develop a simple model of the delivery of bundles of ES along a gradient of land-use intensity. We classify the selected case studies into three groups of mountain landscape dynamics, depending on the main land-use changes: the two first groups are characterized by an increase in land-use intensity with changes towards either croplands or forest plantations respectively. The third group includes cases of decreasing land-use intensity, in which landscapes can be abandoned, rewilded or transformed from productive to multifunctional landscapes. We propose a simple model linking land-use intensity in ecosystems dominated by trees or grass to the provision of eight groups of ES: three provisioning services (food, timber and energy wood, other products), two regulation services (soil conservation and water regulation, carbon sequestration) and two cultural services (spiritual values, recreation, heritage). The analysis of case studies in terms of land-use intensity helps identifying broad groups of mountain landscape trajectories with common features of ES dynamics and highlighting common trade-offs between ES.

AbstractThis inaugural editorial introduces the research topics addressed by the journal Change and Adaptation in Socio-Ecological Systems (CASES). A recent literature analysis revealed that the amount of integrative, interand transdisciplinary research activities on climate and global change, adaptive strategies, actor behaviors and response opportunities has increased significantly in the last few decades. Also, research activities on major drivers for the change and adaptation of socio-ecological systems, namely climate change, socio-economic and political changes and technological development have increased considerably since the 1950s. A publication platform that allows for overarching perspectives, integrative viewpoints, and the exchange of ideas among related disciplines in Socio-Ecological Systems (SES) science is provided by the new journal CASES.

Forests are increasingly recognized for their role, importance and multifunctionality in terms of provisioning, regulating and cultural ecosystem services they provide. Even if timber production remains the most economically valuable provisioning service in Primiero, the importance of and need for multifunctionality of forests is acknowledged. This article analyses the development of Forest Ecosystem Services (FES) governance innovation strategies by the Provincial Forest Agency as a policy entrepreneur in the area of Primiero, in Trentino, northeast of Italy. Based on detailed case study material, we create the heuristic of Kingdon's three streams model in order to reconstruct the development of and negotiations around the introduction of innovative approaches to the problem, policy and politics levels and to identify the chosen or missed windows of opportunity to deliver innovation in FES management. Findings show that the main issues perceived by the local stakeholders concern loss of biodiversity, of cultural identity and historical landscape values. The policy-entrepreneurial initiatives undertaken by the Forest Agency represent a governance mix of direct project execution, financial incentives, organisational incentives and information-based activities. The results highlight its efforts to move beyond the traditional top-down approach based on widely available public funds and towards coordination and collaborations among stakeholders, contribution of private investments, bureaucracy simplification and interconnection between participatory and institutional processes.

International audience ; Climate Action Planning is one of the top priorities of cities in order to reduce greenhouse gas emissions and strengthening climate-resilience, as pointed out by the New Urban Agenda and the Paris Agreement. This study aims at assessing the development of climate change mitigation and adaptation planning in Italian cities. To this end, we analysed the availability of Local Climate Plans (LCPs) in 76 cities, which are included in the Eurostat Urban Audit (UA-2015) database. In a further step, we analysed the content of the urban climate change mitigation and adaptation plans available in a smaller sample of 32 Italian cities of 2007 Eurostat Urban Audit database (UA-3), looking at the single actions undertaken for addressing mitigation and adaptation to climate change. Results show the almost total absence of comprehensive and stand-alone urban climate change adaptation plans in Italy (except for two cities, Ancona and Bologna), whereas we found that in 61 out of 76 cities municipal civil protection plans are the instruments that deal with local emergencies associated to extreme weather events. On the other hand, 56 out of 76 urban climate change mitigation plans (i.e. Sustainable Energy Action Plans) are being developed in the framework of the Covenant of Mayors, which is a transnational network of local governments created by the European Union (EU) in 2012. The results obtained on the mitigation side point out that, in absence of a national law that imposes Italian cities to develop LCPs, transnational networks are an effective boost to voluntary commitment to reach EU climate and energy objectives.

Nature-based solutions (NbS) have the potential to build climate resilience and tackle key societal challenges while also providing multiple co-benefits to biodiversity and human well-being. The demand for nature-based innovation is strongly felt in Malta – a small island state, with the highest population density in the European Union. Against this background, the Horizon 2020 project ReNature (Promoting research excellence in nature-based solutions for innovation, economic growth and human well-being in Malta) has the goal to enhance research excellence of the Malta College of Arts, Science and Technology (MCAST), as well as the national research, policy, business and stakeholder community. The six strategically designed training activities fostering capacity-building and research excellence, delivered during the first half of the project, resulted in useful learning outputs. These are twelve presentations, available as attachments to this article, which cover a large scope of topics related to the implementation of NbS. At a later stage, ReNature will publish another round of learning outputs, resulting from the rest of the training activities planned within the scope of the project.

Nature-based solutions (NBS) is a term often used to refer to adequate green infrastructure that provides multiple benefits to society whilst addressing societal challenges. They are defined as actions to protect, sustainably manage and restore natural or modified ecosystems that address societal challenges effectively and adaptively, simultaneously providing human well-being and biodiversity benefits. Malta, the smallest member state of the EU, has been characterised by rapid economic growth and urbanisation and Maltese citizens had the highest rate of exposure to pollution, grime or other environmental problems, in the EU. The project ReNature aims to establish and implement a nature-based solutions research strategy for Malta with a vision to promote research and innovation and develop sustainable solutions whilst improving human well-being and tackling environmental challenges. Here, we introduce the opening of ReNature collection of research articles in the Open Access Research Ideas and Outcomes (RIO) journal to publish unconventional research outputs and training materials. It will host key outputs relating to the sustainable use of biodiversity, biodiversity – ecosystem functioning, green infrastructure and ecosystem service assessments across rural-urban gradients, equitable access to the benefits derived from nature in cities and socio-environmental justice, payments for ecosystem services, and designing nature-based solutions.

Cities significantly contribute to climate change and at the same time have governance capacity to act efficiently in the field s of mitigation and adaptation. Their capacity is being increasi ngly recognized by international institutions and has been pointed out as crucial i n the multi-level government scenario of the European Union (EU). Addressing the ch allenges of climate change at urban level is a complex issue w hich requires a holistic approach to strategic urban planning. Unders tanding why and how cities start action can help to identify th e barriers they face when addressing climate change, and how national government s, regions and international bodi es can support local authoriti es in their climate fight. This work aims to contribute to the provision of the knowledge needed to gain a better and deeper insight into u rban climate action. The study investigates the state-of -the-art of urban climate plans in Spain and Italy, two countries which share simila rities on many levels (i.e. cultural, geographical, climate vulnerabilities, urban configurations and institutional framework). The research a nalyses cities that are included in the Eurostat Urban Audit (U A), 26 in Spain and 32 in Italy, focusing on the actions taken by large and medium m unicipalities in reducing their contribution to climate change and becoming mo re resilient to changing weather patterns. The results of the a nalysis show a trend towards increasing awarene ss of climate mitigation (highly focused on ener gy efficiency and the promotion of cleaner ener gy sources), while adaptation remains a local policy area in its infancy in both countries. The study also identifies the beneficial influen ce of national and international climate city networks.
