Development of LTSER Platforms in LTER-Europe: Challenges and Experiences in Implementing Place-Based Long-Term Socio-ecological Research in Selected Regions

This chapter introduces place-based, Long-Term Socio-Ecological Research (LTSER) Platforms conceptually and in practice. LTER-Europe has put strong emphasis on utilising the data legacy and infrastructure of traditional LTER Sites for building LTSER Platforms. With their unique emphasis on socio-ecological research, LTSER Platforms add a new and important dimension to the four pillars of LTER-Europe’s science strategy (systems approach, process-oriented, long-term and site-based). In this chapter, we provide an overview of the regionalised or place-based LTSER concept, including experiences garnered from Platform models tested within LTER-Europe, and we discuss the current status of LTSER Platforms on the European continent. The experiences gathered in 6 years of practical work and development of regional socio-ecological profiles as conceptual frameworks in the Austrian Eisenwurzen LTSER Platform will be used to assess weaknesses and strengths of two implementation strategies (evolutionary vs. strategically managed) and to derive recommendations for the future. The chapter represents the close of the first substantive loop of LTSER research that began in 2003 from conceptualisation to implementation and, through the introspective analysis here, a reconsideration of the central concepts.

How much is built? Quantifying and interpreting patterns of built space from different data sources

Land-use/cover change (LUCC) has emerged as a crucial component of applied research in remote sensing. This work compares two methodologies, based on two data sources, for assessing amounts of land transformed from open to built space in three regions in Israel. We use a decision-tree methodology to define open and built space from remotely sensed (RS) Landsat data and a geographic information systems (GIS) platform for analysing 1:50 000 scale survey maps. The methodologies are developed independently, used to quantify and characterize the spatial pattern of built space, and then analysed for their strengths and weaknesses. We then develop a method for combining the built area maps derived from each methodology, capitalizing on the strengths of each. The RS methodology had higher omission errors for built space in areas with high vegetation levels and low-density exurban development, but high commission errors in the arid region. The GIS analysis generally had fewer errors, although systematically missed built surfaces that were not specifically buildings or roads, as well as structures intentionally omitted from the maps. We recommend using maps for baseline estimates whenever possible and then complementing the estimates with clusters of built areas identified with the RS methodology. The results of this comparative study are relevant to both researchers and practitioners who need to understand the strengths and weaknesses of mapping techniques they are using.

Population Growth and Environmental Impact: Ideology and Academic Discourse in Israel

This article addresses the discourse of Israeli academics, policy makers, and environmental activists regarding the environmental implications of population growth in Israel. While there are compelling reasons that population growth should be a prominent topic for local environmental research and discussion, it is rarely considered in environmental campaigns or in the academic literature. I attribute this to the embeddedness of the Israeli environmental community within wider Israeli society. National ideologies and religiosity, coupled with immediate security and social concerns, bound what is considered “sanctioned” discourse regarding population growth, prescribing the rules of academic engagement for this controversial topic.

Changes in biodiversity and trade-offs among ecosystem services, stakeholders, and components of well-being: the contribution of the International Long-Term Ecological Research network (ILTER) to Programme on Ecosystem Change and Society (PECS)

The International Long-Term Ecological Research (ILTER) network comprises > 600 scientific groups conducting site-based research within 40 countries. Its mission includes improving the understanding of global ecosystems and informs solutions to current and future environmental problems at the global scales. The ILTER network covers a wide range of social-ecological conditions and is aligned with the Programme on Ecosystem Change and Society (PECS) goals and approach. Our aim is to examine and develop the conceptual basis for proposed collaboration between ILTER and PECS. We describe how a coordinated effort of several contrasting LTER site-based research groups contributes to the understanding of how policies and technologies drive either toward or away from the sustainable delivery of ecosystem services. This effort is based on three tenets: transdisciplinary research; cross-scale interactions and subsequent dynamics; and an ecological stewardship orientation. The overarching goal is to design management practices taking into account trade-offs between using and conserving ecosystems toward more sustainable solutions. To that end, we propose a conceptual approach linking ecosystem integrity, ecosystem services, and stakeholder well-being, and as a way to analyze trade-offs among ecosystem services inherent in diverse management options. We also outline our methodological approach that includes: (i) monitoring and synthesis activities following spatial and temporal trends and changes on each site and by documenting cross-scale interactions; (ii) developing analytical tools for integration; (iii) promoting trans-site comparison; and (iv) developing conceptual tools to design adequate policies and management interventions to deal with trade-offs. Finally, we highlight the heterogeneity in the social-ecological setting encountered in a subset of 15 ILTER sites. These study cases are diverse enough to provide a broad cross-section of contrasting ecosystems with different policy and management drivers of ecosystem conversion; distinct trends of biodiversity change; different stakeholders’ preferences for ecosystem services; and diverse components of well-being issues.

Genesis, goals and achievements of Long-Term Ecological Research at the global scale: A critical review of ILTER and future directions

Since its founding in 1993 the International Long-term Ecological Research Network (ILTER) has gone through pronounced development phases. The current network comprises 44 active member LTER networks representing 700 LTER Sites and ~80 LTSER Platforms across all continents, active in the fields of ecosystem, critical zone and socio-ecological research. The critical challenges and most important achievements of the initial phase have now become state-of-the-art in networking for excellent science. At the same time increasing integration, accelerating technology, networking of resources and a strong pull for more socially relevant scientific information have been modifying the mission and goals of ILTER. This article provides a critical review of ILTERs mission, goals, development and impacts. Major characteristics, tools, services, partnerships and selected examples of relative strengths relevant for advancing ILTER are presented. We elaborate on the tradeoffs between the needs of the scientific community and stakeholder expectations. The embedding of ILTER in an increasingly collaborative landscape of global environmental observation and ecological research networks and infrastructures is also reflected by developments of pioneering regional and national LTER networks such as SAEON in South Africa, CERN/CEOBEX in China, TERN in Australia or eLTER RI in Europe. The primary role of ILTER is currently seen as a mechanism to investigate ecosystem structure, function, and services in response to a wide range of environmental forcings using long-term, place-based research. We suggest four main fields of activities and advancements for the next decade through development/delivery of a: (1) Global multi-disciplinary community of researchers and research institutes; (2) Strategic global framework and strong partnerships in ecosystem observation and research; (3) Global Research Infrastructure (GRI); and (4) a scientific knowledge factory for societally relevant information on sustainable use of natural resources.

Methodology Matters: Measuring Urban Spatial Development Using Alternative Methods

The effectiveness of policies implemented to prevent urban sprawl has been a contentious issue among scholars and practitioners for at least two decades. While disputes range from the ideological to the empirical, regardless of the subject of dispute, participants must bring forth reliable data to buttress their claims. In this study we discuss several sources of complexity inherent in measuring sprawl. We then exhibit how methodological decisions can lead to disparate results regarding the quantification and characterization of sprawl. We do so by employing three GIS-based methods for quantifying the amount and defining the configuration of land-cover change from open to built space in a 350 km2 area in central Israel over a five-year period. We then calculate values for a variety of spatial indices commonly associated with urban sprawl. Our results reveal that some urban growth patterns are so robust that multiple methods and indices yield similar results and thus lead to similar conclusions. However, we also note that many divergent and even contradictory results are produced depending on the measurement method used and the index selection.

Can Urban Growth Management Work in an Era of Political and Economic Change

Problem: Urban growth management policy employs a range of tools to restrain urban sprawl, promote efficient land use, and preserve open space. Yet the efficacy of such policy is widely debated and challenged, necessitating reliable empirical evidence from case studies assessing the historical success (or failure) of such policy. Purpose: We review Israeli national growth management policy over a 36-year period, recording long-term land development trends in order to assess the efficacy of policy. Methods: We integrate a historical analysis of qualitative policy data and quantitative performance indicators of urban spatial development for a selected region of the country. We use a suite of spatial variables indicating amount, distribution, and configuration of built space along with other sprawl-relevant statistical data. Results and conclusions: In the 1970s and 1980s, open space was preserved largely due to agricultural preservation policy, despite demographic and economic growth. During the 1990s, the initiation of growth management policy coincided with a profound proliferation of development and population movement to low-density suburbs. While statistical indicators from the past several years are equivocal, they suggest that policy is encouraging higher-density development and slowing the loss of open space. Takeaway for practice: Urban growth management policy and its impact must be considered within the historical context in which it was implemented. Changes in land use policy in Israel reflect socioeconomic and political changes; when policy did not adapt to changes in society, the results were undesirable. Today, planning tools (e.g., minimum density limits, population size thresholds, urban growth boundaries, and land use fabrics) strike a balance between top-down planning objectives and bottom-up development pressures. The use of these tools within a statutory, national-level plan helps ensure consistency of implementation across regions.

What is socio-ecological research delivering? A literature survey across 25 international LTSER platforms

With an overarching goal of addressing global and regional sustainability challenges, Long Term Socio-Ecological Research Platforms (LTSER) aim to conduct place-based research, to collect and synthesize both environmental and socio-economic data, and to involve a broader stakeholder pool to set the research agenda. To date there have been few studies examining the output from LTSER platforms. In this study we enquire if the socio-ecological research from 25 self-selected LTSER platforms of the International Long-Term Ecological Research (ILTER) network has produced research products which fulfil the aims and ambitions of the paradigm shift from ecological to socio-ecological research envisaged at the turn of the century. In total we assessed 4983 publically available publications, of which 1112 were deemed relevant to the socio-ecological objectives of the platform. A series of 22 questions were scored for each publication, assessing relevance of responses in terms of the disciplinary focus of research, consideration of human health and well-being, degree of stakeholder engagement, and other relevant variables. The results reflected the diverse origins of the individual platforms and revealed a wide range in foci, temporal periods and quantity of output from participating platforms, supporting the premise that there is a growing trend in socio-ecological research at long-term monitoring platforms. Our review highlights the challenges of realizing the top-down goal to harmonize international network activities and objectives and the need for bottom-up, self-definition for research platforms. This provides support for increasing the consistency of LTSER research while preserving the diversity of regional experiences.

The immersive visualization theater: A new tool for ecosystem assessment and landscape planning

Abstract In this study focusing on human–environment interactions, we analyze the use of an immersive visualization theater (IVT) for exploring how humans use and value cultural ecosystem services provided by natural landscapes in Israels Carmel Forest. Our goal in this inductive, exploratory study is to assess the impact of the IVT on the quality and content of stakeholder discussions held in the theater. We facilitated 10 focus group discussions in the IVT, where a series of high-resolution photographs were projected. Participants were asked (in writing and orally) to choose from among the scenes where they would prefer to spend time, and then asked to explain their answers. Next, they were asked to describe activities in selected scenes in which they were likely to participate. We suggest that the immersion theater, due to screen size, photo resolution, social interaction, and group isolation within the theater, elicited attention to detail and triggered memories and sensory responses to various landscapes. The qualitative data derived from focus group discussions add to our understanding of the diverse meanings and importance that different people attribute to the landscape, contribute to understanding the social processes and conditions through which participants attribute value to cultural ecosystem services, and allow us to generate testable hypotheses for continuing research.

Ecosytem Services: A Rapid Assessment Method Tested at 35 Sites of the LTER-Europe Network

Abstract The identification of parameters to monitor the ecosystem services delivered at a site is fundamental to the concept’s adoption as a useful policy instrument at local, national and international scales. In this paper we (i) describe the process of developing a rapid comprehensive ecosystem service assessment methodology and (ii) test the applicability of the protocol at 35 long-term research (LTER) sites across 14 countries in the LTER-Europe network (www.lter-europe.net) including marine, urban, agricultural, forest, desert and conservation sites. An assessment of probability of occurrence with estimated confidence score using 83 ecosystem service parameters was tested. The parameters were either specific services like food production or proxies such as human activities which were considered surrogates for cultural diversity and economic activity. This initial test of the ecosystem service parameter list revealed that the parameters tested were relatively easy to score by site managers with a high level of certainty (92% scored as either occurring or not occurring at the site with certainty of over 90%). Based on this assessment, we concluded that (i) this approach to operationalise the concept of ecosystem services is practical and applicable by many sectors of civil society as a first screen of the ecosystem services present at a site, (ii) this study has direct relevance to land management and policy decision makers as a transparent vehicle to focus testing scenarios and target data gathering, but (iii) further work beyond the scale investigated here is required to ensure global applicability.
