Landscape concepts and approaches foster learning about ecosystem services
No full textThe ecosystem services framework aims to encourage ecological sustainability through political-economic decisions. However, it fails to capture the complexity of social–ecological interactions. This is an obstacle for coping with current grand challenges through integrative knowledge production and collaborative learning. Landscape concepts and approaches, which emphasize human–environment interactions, governance and stewardship, can help overcome this obstacle. In particular, landscape concepts and approaches can help resolve the integrative and operational gaps encountered in the ecosystem services framework as a means of communicating evidence-based knowledge about the state and trends of ecosystems. The goal of this Special Issue is to address how different interpretations of landscape can support knowledge production about ES, and how applying landscape approaches on the ground can encourage more collaborative and sustainable land management alternatives. The effectiveness of the ecosystem services framework can be improved by (1) the use of landscape concepts to build bridges to different disciplines, arts and practice, as well as to build SMART sustainability indicators, and (2) the application of holistic landscape approaches for place-based knowledge co-production and collaborative learning across multiple governance levels. This forms the base for a research infrastructure integrating methods from the natural and social sciences through macroecology, comparative politics, and regional studies. While place-based research using landscape concepts can help develop more sustainable alternatives for land management, scaling up landscape approach initiatives towards landscape stewardship and fostering collaborations among initiatives are paramount challenges.PA acknowledges funding from EU Horizon 2020 for the research infrastructure project eLTER, the Swedish Research Council FORMAS (project number 2017:1342), the Lithuanian Science Council (project number P-MIP-17-107), and the 2018-19 Alter-Net High Impact Action.

Multi-scale mapping of cultural ecosystem services in a socio-ecological landscape: A case study of the international Wadden Sea Region
Full text linkContext
The governance of international natural World Heritage sites is extremely challenging. In the search for effective multilevel governance there is a need to identify the community of people which have place attachment to the areas, i.e. ‘the community of fans’ at local to international levels.
Objectives
Focusing on the landscape of the international Wadden Sea coastal area in the Netherlands, Germany and Denmark as a case study, we address three key questions: What is the spatial distribution of the community of fans? How does the size of this community relate to the overlapping communities of locals and actual visitors to the Wadden Sea coastal area? Which parts of the Wadden Sea coastal area are most appreciated by the community of fans, and how does this relate to its formal protection status?
Methods
We analysed 7650 respondents’ answers to a tri-lateral web survey (the standardized Greenmapper survey) conducted in Denmark, Germany and the Netherlands.
Results
We estimated that 14 million German, Dutch and Danish citizens can be regarded as the potential—national level—community of fans. The correlation between place or landscape attachment and distance was varied among the three countries. Furthermore, only 37% of the markers placed by fans of the Wadden Sea coastal area are within the protected UNESCO World Heritage limits, suggesting that a broader demarcation could be possible.
Conclusions
We discuss how the identification of fans can potentially contribute to more effective public involvement in the governance of valuable landscapes.This publication is part of the activities performed within the framework of the Wadden Sea Long-Term Ecosystem Research (WaLTER) Project, funded by the Dutch Waddenfonds and the Provinces of Noord-Holland and Friesland.

Linking Cork to Cork Oak Landscapes: Mapping the Value Chain of Cork Production in Portugal
No full textTraditional farming landscapes in South and Central Portugal, known as montados, are
affected by global socio-economic and biophysical pressures, putting the sustainability of
the systems in jeopardy. Cork oak trees (Quercus suber L.) are characteristic features of
these complex agro-silvo-pastoral agroforestry systems, delivering a globally important
product, cork. The increasingly distant, global scale of decision making and trade can
consequently be observed on the local, landscape, scale. In this study, we use a value
chain approach to test the concept that landscape products can ensure sustainable
management of the landscape of origin. We interviewed agents—cork producers,
intermediaries, industrial transformers, and winemakers—about the challenges they
perceived in the business and how these were connected to the landscape of origin. We
illustrate the network of agents and sub-actors involved in the sector and highlight the
most prominent concerns. We conclude that this approach can reveal the major points
for determining the future of the montado, and we suggest that collaboration amongst
value chain agents can be a pathway to landscape sustainability
Agroforestry for Sustainable Landscape Management
No full textAgroforestry and sustainable landscape management are key strategies for implementing the UN-Sustainable Development Goals across the world’s production landscapes. However, both strategies have so far been studied in isolation from each other. This editorial introduces a special feature dedicated to scrutinizing the role of agroforestry in sustainable landscape management strategies. The special feature comprises eleven studies that adopt inter- and transdisciplinary perspectives, integrating ecological, agricultural, and socio-economic sciences, and in some cases also practical knowledge. The studies relate to a range of different ecosystem goods and services, and to a diversity of societal sectors (e.g., agriculture, forestry, nature conservation, urban planning, landscape protection) and demands, including their mutual synergies and trade-offs. They inform land-use policy and practice by conceptualizing agroforestry as a set of “nature-based solutions” useful to help tackle multiple societal challenges. The studies encompass four themes: social-ecological drivers, processes, and impacts of changes of agroforestry landscapes; the sustainability outcomes of agroforestry at landscape scale; scaling up agroforestry through multi-stakeholder landscape strategies; and development of conceptual and operational tools for stakeholder analysis in agroforestry landscape transitions. Key steps to harness agroforestry for sustainable landscape management comprise: (i) moving towards an “agroforestry sustainability science”; (ii) understanding local land-use trajectories, histories, and traditions; (iii) upscaling agroforestry for landscape-scale benefits; (iv) promoting the multiple economic, environmental, social, and cultural values of agroforestry; (v) fostering inclusive forms of landscape governance; and (vi) supporting the innovation process of agroforestry system analysis and design.Open Access funding provided by Projekt DEAL.

Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
