Co-Creation of Knowledge for Ecosystem Services Approach to Spatial Planning in the Basque Country

: Sustainable development has to be based on scientiﬁc knowledge, social agreements, and political decisions. This study aimed to analyse the implementation of the ecosystem services approach (ESA) in the spatial planning of the Basque Country, via the co-creation of knowledge. This paper uses a proposal for a regional green infrastructure (GI) to examine the co-creation of knowledge process. It addresses the community of practice; a process of co-creation of knowledge through workshops and meeting, SWOT (Strengths, Weaknesses, Opportunities, and Threats) analysis using an online survey, and mapping and identiﬁcation of the multifunctional areas that provide ecosystem services (ES) to develop a GI. Results indicate that ESA has been included in spatial planning actions at di ﬀ erent scales (biosphere reserve, metropolitan area, and region). This subsequently created an avenue for understanding the political necessities at play, so that scientists can develop useful tools for sustainable development. The ﬁndings also draw attention to the importance of establishing a constructive and mutually comprehensible dialogue between politicians, technical experts and scientists. For ES to be part of spatial planning, ESA has to be taken into account at the beginning of the planning process. We conclude that building bridges between science and spatial planning can help establish science-based management guidelines and tools that help enhance the sustainability of the territory.


Introduction
The social and environmental problems that characterise the global change in the new Anthropocene era pose major challenges for the research community, decision-makers, and civil society organisations in general [1]. What is needed to rise to these challenges are solution-centred approaches and research that offer greater insight into both nature itself and the interactions that take place between nature and society.
Global change has many different causes and it is difficult to separate the effects of each. For example, in the case of land ecosystems, changes in land use constitute an important driving force that acts simultaneously with climate change to impact biodiversity and ecosystem processes [2]. This is why it is increasingly important to apply sustainable landscape management practices, particularly in highly anthropised areas.
Large-scale international research programmes recognise the need to deal with the environmental crisis from the perspective of complex adaptive systems [3], accepting the link which exists between ecosystems and human systems. One example is the socio-ecological systems approach [4]. Within this In the Basque Country (Spain), a highly developed region with an extremely fragmented landscape in which natural ecosystems have been sorely degraded, it is particularly important to ensure sustainable landscape management which takes ES into account. To do this, it is necessary to include the ESA in spatial planning policies. Some recent reviews have highlighted the enormous gap that still exists in the use of the ESA to inform spatial planning processes [22,23]. Thus, the aim of this study is to analyse the work carried out within a CoP to implement the ESA in the spatial planning of the Basque Country, via the co-creation of knowledge. The study explores the keys to success in the implementation of ESA in spatial planning, as well as the challenges involved in developing this process. The planning for the GI of the Basque Country using the ESA is shown as an example of the implementation of the ESA on the co-creation of knowledge within the CoP.

Study Area
The Basque Country is an Autonomous Community located in Northern Spain. It covers a surface area of 7200 km 2 and encompasses the provinces of Bizkaia, Gipuzkoa, and Araba ( Figure 1). It has a population of 2,200,000 inhabitants, of which over 50% live in Bizkaia, which has a population density of 520 inhabitants/km 2 . Geographically, the Basque Country is located on the border between the Atlantic and Mediterranean biogeographic regions. Consequently, Bizkaia and Gipuzkoa have a temperate rainy climate, with small temperature variations (mean temperature: 12.5 • C) and a uniform distribution of rainfall throughout the year (mean annual rainfall: 1500 mm). In contrast, Araba has a more Mediterranean climate, with larger temperature variations (mean temperature: 4º C in winter and 20 • C in summer), less rainfall (mean annual rainfall: 850 mm), which is concentrated mainly in autumn and spring, and more frequent frosts. Differences in climate and topography have given rise to different land uses in the two regions. Thus, while timber exotic plantations cover 45% of the surface area of Bizkaia and Gipuzkoa, 26% of the land in Araba is used for intensive monoculture, with the principal crops being potatoes, cereal, and vines [24]. The result of this is a highly fragmented landscape in which natural ecosystems cover only a small percentage of their potential habitat. Sustainability 2020, 12, x FOR PEER REVIEW 3 of 17 ensure sustainable landscape management which takes ES into account. To do this, it is necessary to include the ESA in spatial planning policies. Some recent reviews have highlighted the enormous gap that still exists in the use of the ESA to inform spatial planning processes [22,23]. Thus, the aim of this study is to analyse the work carried out within a CoP to implement the ESA in the spatial planning of the Basque Country, via the co-creation of knowledge. The study explores the keys to success in the implementation of ESA in spatial planning, as well as the challenges involved in developing this process. The planning for the GI of the Basque Country using the ESA is shown as an example of the implementation of the ESA on the co-creation of knowledge within the CoP.

Creation of a Community of Practice for Implementing the ESA in Spatial Planning
In 2013, a transdisciplinary CoP involving politicians, technical experts and scientists was set up within a project entitled Assessment of the Ecosystem Services of the Basque Country. The aim was to combine the scientific, political, technical, and social perspectives in order to obtain scientific knowledge that would be useful for conservation and sustainable landscape management policies [25,26]. This CoP is coordinated by the UNESCO Chair on Sustainable Development and Environmental Education at the University of the Basque Country (UPV/EHU) and is made up of researchers from the UPV/EHU, technical and political staff from the public administrations (Regional Basque Government, provincial councils and local councils) and associations (Non-Governmental Organizations (NGOs)and businesses, etc.). The size and composition of the CoP has varied over the years, depending on the availability of and interest expressed by the different public

The size and composition of the CoP has varied over the years, depending on the availability of and interest expressed by the different public administration departments (see Appendix A). To date, around 60 technical and scientific experts and 5 politicians have participated.

Knowledge Co-Creation Process Assessment
The working process of the CoP comprises systematic annual meetings with key stakeholders (average of 6 annual meetings), as well as open workshops targeted at other interested stakeholders (average of 2 annual workshops) (see Appendix A). These meetings and workshops follow the outline proposed for transdisciplinary knowledge systems, which comprises five phases: mobilise, translate, negotiate, synthesise, and apply [27] (see Figure 2). These five stages formed the basis for examining the knowledge co-creation process in the ESA in the Basque Country. To mobilise means to bring out the knowledge contributed by the different knowledge systems/stakeholders into a form that can be shared. In this case, the knowledge about the role of ES in the Basque Country for human well-being, the applicability of ESA for spatial planning, and the information available and indicators for mapping the ES, tools and guidelines, among others, were shared by the different stakeholders in workshops and meetings. To translate implies making the information understandable to the different knowledge systems, to enable mutual comprehension. In this case, the use of language, concepts and approach that are familiar and easy to understand by all stakeholders. To negotiate means establishing convergences between the different types of knowledge in relation to the shared goal, although in the event of conflicts some divergences may remain. In this case, the aim was clear, the incorporation of the ESA into the spatial planning. Thus, different management plans were proposed and analysed for the incorporation of ESA. To synthesise is to establish a common knowledge, even though the integrity of each knowledge system is maintained. Scientifics helped by technicians and politics developed maps, tools, and guides for the ESA implementation. To apply is the final phase, in which the knowledge generated is rendered usable for decision-making for all stakeholders involved. ESA was incorporated into management plans at different levels.

Finally, to analyse the strengths, weaknesses, opportunities, and threats of the integration of ESA in spatial planning according to the stakeholders, 10 technical experts working at the Bizkaia Provincial Council were asked to complete SWOT (Strengths, Weaknesses, Opportunities, and Threats) matrices. From this exercise, 22 statements were extracted in connection to the integration of ES in spatial planning (Appendix B). These statements were assessed by 115 people working in some capacity in the environmental field by means of an online survey, in which respondents were asked to rate the extent to which they agreed or disagreed with each statement on a scale of 1 to 5 (1 = totally disagree, 5 = totally agree). The survey was carried out in March 2019; 59% of respondents were men and 52% were aged 50 years or over. The data were analysed using the Mann-Whitney U test and the Kruskal-Wallis test.

Proposal for a Regional Green Infrastructure Using the ESA
To identify the components that may form part of a GI, it is first necessary to identify the multifunctional areas that provide ES. To this end, first of all, within the CoP, the priority regulating ES were identified (habitat maintenance, air purification, carbon storage, water flow regulation, and pollination) [28]. Subsequently, their spatial distributions were mapped (very high, high, medium, low and very low) in accordance with the methodology outlined in [29,30], and the maps of these ES were overlaid. Those areas that had high or very high values for all ES were identified as principal components, and those with high or very high values for four of them were identified as secondary components [31]. The indicators used to map ES and the methodology for their calculation are shown in Table 1.  The software used for geoprocessing was ArcMap 10.3 [32] and the land use categories employed to assess the ES were those featured on the EUNIS map of the European Nature Information System, at a scale of 1:10,000 [24]. All ES were assigned to one of five categories: very high, high, medium, low, and very low/no contribution. These categories were defined using the Jenks natural breaks classification method [33,34].

Outcomes of Knowledge Co-Creation Process
The co-creation of knowledge within the CoP achieved the following key milestones, ordered chronologically: (1) a multifunctional regional indicator (MESLI) based on ES at a municipal level [35]; (2) a methodological guidelines for mapping ES in the Basque Country [36]; (3) mapping the ES of the Basque Country (food production, timber production, habitat maintenance, air purification, carbon storage, water flow regulation, pollination, recreation, and aesthetic value of the landscape) (see Figure 3) [36,37]; and (4) a practical guide to formulating spatial and urban planning programmes using the ESA. The aim of this guide is to provide local and regional administrations with a clear, coherent set of technical, methodological, and conceptual guidelines to help them formulate spatial and urban planning programs, incorporating the ESA right from the initial stages of development. The guide is designed as a working tool targeted mainly at technical experts working in public administrations, sub-provincial associations, consortia, and representatives from the private sector (environmental consultants and architecture or planning studios, etc.), academia (universities and technology centres), and the social field (NGOs and environmental associations) [36].

Application of Knowledge Co-Creation Outcomes
ESA has been included in spatial planning actions at different levels. For example, ESA was used: (1) to establish criteria for the Renewed Uses and Management Master Plan (UMMP) for the Urdaibai Biosphere Reserve [38,39]. Appendix I of the UMMP explains that the services provided by ecosystems in the Urdaibai Biosphere Reserve will be identified [40]; (2) to establish criteria for the Renewed Partial Territorial Plan (PTP) for the Bilbao Metropolitan Area. The ES map was included, along with a GI proposal for the Bilbao Metropolitan Area [29] in the diagnosis carried out for the revised PTP [41]; (3) to identify the components that may form part of the GI of the Basque Country ( Figure 4). The principal components corresponded mainly to natural forests, and the secondary ones to pastureland, scrubland, and heaths; and (4) to include ES and GI in the Renewed Spatial Planning Guidelines (SPGs) of the Basque Country approved in 2019 (Decree 128/2019, of 30 July) [42]. The contributions made are mainly linked to terminology and the methodology used to assess ES in the Basque Country, which was included as an Appendix to the SPGs in the form of a method sheet.
One direct consequence of the approval of the SPGs is that the different departments of the public administration now have the obligation to implement actions at different scales to promote a local GI. along with a GI proposal for the Bilbao Metropolitan Area [29] in the diagnosis carried out for the revised PTP [41]; (3) to identify the components that may form part of the GI of the Basque Country ( Figure 4).

SWOT Analysis of the Knowledge Co-Creation Process
The results of the survey indicated that the statements with which respondents agreed most were that budgetary cutbacks may hamper the integration of ES into landscape management and that ES are not currently a priority on the political agenda, due to a lack of awareness among political and economic authorities (Figures 5 and 6). Respondents disagreed most with statements linked to the ES concept itself and the way it is disseminated since they considered that even though it is not a difficult concept to adapt to the public discourse, it does need to be expressed using language and terms that can more easily be understood by the general public ( Figures 5 and 6).

A New Approach to Sustainable Spatial Planning
The ESA was applied for the first time to strengthen nature conservation policies within the framework of the EU Convention on Biological Diversity and the EU Biodiversity Strategy 2020. Nevertheless, mapping and assessment of ES, which is required by Action 5 of this strategy, is not only important for achieving biodiversity targets; it is also strongly linked to the implementation of other related policies [43]. The ESA provides an ideal comprehensive framework for facilitating planning and development decisions in all sectors, at all scales, and across administrative boundaries [44,45].

A New Approach to Sustainable Spatial Planning
The ESA was applied for the first time to strengthen nature conservation policies within the framework of the EU Convention on Biological Diversity and the EU Biodiversity Strategy 2020. Nevertheless, mapping and assessment of ES, which is required by Action 5 of this strategy, is not only important for achieving biodiversity targets; it is also strongly linked to the implementation of other related policies [43]. The ESA provides an ideal comprehensive framework for facilitating planning and development decisions in all sectors, at all scales, and across administrative boundaries [44,45]. Thus, assessing and mapping ES are key requirements for implementing the ESA in decision-making processes, particularly in relation to sustainable spatial planning and landscape management, and the development of GI. In this sense, a map of priority ES has been compiled in the Basque Country, along with a methodological guide for mapping. Both have subsequently been used for spatial planning purposes, as in the case of the Basque SPGs approved in 2019. Article 4 of the SPGs establishes a series of guidelines for GI and ES, defining the elements that make up a GI and its characteristics. The article highlights the fact that the infrastructure of this kind should check the loss of biodiversity and mitigate the effects of spatial fragmentation, with the aim of strengthening the services offered by nature. The article also states that the ES assessment should contain information about their scope and condition, the services they provide, and their value.
The concept of GI was incorporated into Spanish law in Act 33/2015, of 21 September, modifying Act 42/2007, of 13 December, on Natural Heritage and Biodiversity. This Act stipulated that the Ministry for the Environmental Transition with the collaboration of the Autonomous Communities and other Ministries involved in some way would develop, within the maximum period of three years, a National Strategy for GI, Connectivity, and Environmental Restoration. The text of this national strategy states that the conservation of GIs is crucial to ensuring environmental connectivity, the functionality of ecosystems, the mitigation of and adaptation to climate change, the defragmentation of strategic areas, and the restoration of degraded ecosystems. Therefore, identifying, promoting, and preserving GI has the potential to provide a wide range of environmental, economic, and social benefits [46]. The regional governments in Spain play a key role in the implementation of an effective GI based on scientific/technical approaches designed to support sustainable spatial planning and landscape management policies under the umbrella of the ESA. This has been carried out in the Basque Country, in collaboration with a CoP constituted for this very purpose and made up of scientists, technical experts, and politicians. The methodology presented in this study on the use of a CoP for integrating the ESA into spatial planning may constitute a useful tool for spatial planning managers/decision-makers worldwide. In the case of the Basque Country, it has enabled the implementation of the ESA in the spatial planning of a Biosphere Reserve (Urdaibai UMMP), a metropolitan area (Bilbao Metropolitan Area PTP), and at a regional scale (Basque Country SPGs approved in 2019).

Lesson Learned: Challenges for Policy Implementation and Key Success Factors
Several important lessons were learned during this process, including the need for scientists, technical experts, and politicians to work together to implement the ESA in spatial planning and its related policies. It is also important to understand the political necessities at play, so that scientists can develop useful tools for the sustainable management of the region at different scales. Moreover, it is vital to establish a constructive and mutually comprehensible dialogue between both parts (science and politics) within a CoP designed to aid the co-creation of knowledge. ES need to be a priority on the political agenda and funds must be earmarked in the budget to integrate them into spatial planning, as well as to enable scientists to have access to useful information for developing effective tools for technical experts and politicians. The ESA should be taken into account right at the beginning of the planning process [45], and transdisciplinarity is vital in the CoP in order to enable different perspectives to be analysed in relation to a shared goal. Finally, it is important to develop guidelines for technical experts and politicians, to help them implement the ESA at different scales. Other authors have also highlighted the lack of institutional guidelines at different planning and administrative levels for incorporating the ESA into spatial planning processes [47].
The linking of knowledge systems requires a learning process across key aspects of the system and procedures [27], which needs a change of paradigm and usually presents difficulties. Science-policy deals such as the Inter-governmental Platform on Biodiversity and Ecosystem Services (IPBES) acknowledge the importance of support a diversity of knowledge systems to inform decision-making [48]. In this framework, there is a recognition that different approaches have to be adapted depending on the particular contexts of different knowledge systems [49]. Moreover, a transparent participatory approach is required to facilitate implementation of results [50]. In the study case, some challenges appear to be key factors of limiting successful results, and these were analysed and managed in different ways throughout the developed activities of the CoP.
An important challenge highlighted by managers in the studied situation was the difficulty for managers and stakeholders to understand the language and terms used by scientist and researchers on ESA. In this sense, it would be a necessary approach to use easy terms that would be definitely understood by the public, as proposed by other authors [51]. At the beginning of the process, the terms used when working in the CoP were in relation to the full set of benefits from ecosystems, without explicitly referencing ES. The more technical and specific terms about ESA were introduced incrementally, facilitating a shared language.
Likewise, adoption of policies and management objectives in planning based on ESA require, not only a policy-relevant research [52], but also a vision and a strong commitment from decision-makers [53]. In the case of the Basque Country, managers considered a lack of awareness among political and economic authorities as a big challenge for a successful implementation of the ESA in management. One of the most important efforts of the developed CoP was to explain the benefits of the ESA approach, and explain that it does not imply eliminating other previous methodologies, but rather complementing them. This was a good way to overcome system reluctance and fight the inertia of the system (business as usual), as even the awareness of the authorities is still a question to be solved progressively.
Moreover, budgetary cutbacks appear to be one of the most important factors that hamper the integration of ES into management in the study case, probably due to the lack of awareness of authorities. This situation has been recognised as a critical component for success by previous practitioners and managers, such as the US Forest Service [51]. This is not easy to overcome, but the way to improve this aspect is in relation with the previous ones, adopting an understandable language, and a transdisciplinary knowledge thorough a CoP is a factor to success.

A New Paradigm for Science: Sustainability
Given the current global crisis, we need to define a new way of creating knowledge for sustainability. Since the first definition of sustainable development in the Brundtland Report of 1987, the term has been understood to refer to the need for economic and social development in balance with nature conservation, which does not lead to the depletion of natural resources. It took 20 years for the idea to give rise to a new kind of science capable of bringing together the knowledge and methods of many different disciplines within the framework of a new conceptual and practical concept [54]. Thus, it was with the turn of the new millennium that Sustainability Science became the focus of intense interest, representing as it did the scientific collaboration between different researchers and research centres [55]. In recent years, there has been a growing shift towards a more transformational outlook based on biospheres [27], and oriented towards solving real problems and bringing about a specific change [56].
However, in order to really move towards scenarios of true sustainability, much more than science and solution-oriented sustainability research is required. There is still a scarcity of both capacity and willingness in academic, governmental and private organisations, both profit-making and non-profit NGOs, to use scientific findings in knowledge-generating operations [57]. Consequently, the development of the ESA and its transdisciplinary nature (a collaboration between all social stakeholders) may prove vital on the road to sustainability.
To build social, economic, and environmental resilience, knowledge needs to be embedded in an institutional context that enables its application, as well as in a desire to learn from the experience over time [58]. In this context, the university has a key role to play in connecting science to practice and developing outlooks involving social engagement [59].

Conclusions
The results presented here indicate that the bridges between science and management may be successful in establishing science-based decision-making/management guidelines. One of the conditions required to implement research findings is a collaboration between researchers, managers, and decision-makers, which in turn facilitates knowledge exchange, the generation of shared understanding, and the application of the results.
In this case, the ESA has been incorporated into the spatial planning of the Basque Country at different levels: in the Urdaibai Biosphere Reserve UMMP, the diagnosis for the review of the Bilbao Metropolitan Area PTP, and the renewed version of the Basque Country SPGs, which also has implications at lower scales. The CoP has made it possible for scientists, with the aid of technical experts, to provide local administrations with key tools for ensuring the sustainable management of the region.  -Dept. of the environment, spatial planning and housing: • Deputy regional minister for the environment • Director and head of the natural environment and environmental planning • Deputy regional minister for spatial planning • Director, department head and 7 spatial and urban planning and urban regeneration experts
