How Personal Judgment Influences Scenario Development: an Example for Future Rural Development in Europe Ecology and Society
Metzger, Marc J.; Centre for the Study of Environmental Change and Sustainability (CECS), University of Edinburgh ; Alterra Wageningen University and Research Centre; marc.metzger@ed.ac.uk; Rounsevell, Mark D.A.; Centre for the study of Environmental Change and Sustainability (CECS), University of Edinburgh;; Van den Heiligenberg, Harm A.R.M.; Netherlands Environmental Assessment Agency (PBL); Province of Utrecht;; Soto Hardiman, Paul; Grupo Alba;.
Scenarios of alternative plausible futures have been used extensively to explore the potential effects of socioeconomic and environmental change. The ultimate objective of any explorative scenario exercise is to assess the variation in possible futures to provide insights into the range of potential outcomes. These results provide stakeholders with guidance for policy development, planning, and management. We explore how personal judgment can influence scenario development. Scenarios for the future of European rural regions are used to explore alternative outcomes under a public interventionist future and a market liberalization oriented future. A transparent qualitative framework is used to identify differences in outcomes based on personal judgment....

Observations on Drivers and Dynamics of Environmental Policy Change: Insights from 150 Years of Forest Management in British Columbia Ecology and Society
Hagerman, Shannon M; Institute for Resources, Environment and Sustainability, University of British Columbia; University of Washington, Climate Impacts Group; hshannon@interchange.ubc.ca; Dowlatabadi, Hadi; University of British Columbia; Resources for the Future; Carnegie Mellon University; hadi.d@ubc.ca; Satterfield, Terre; University of British Columbia; satterfd@interchange.ubc.ca.
Human and ecological elements of resource management systems co-adapt over time. In this paper, we examine the drivers of change in forest management policy in British Columbia since 1850. We asked: How has a set of system attributes changed over time, and what drivers contributed to change when it occurred? We simultaneously examined a set of three propositions relating to drivers and dynamics of policy change. We find that factors contributing to the level of impacts, like technology, changed substantially over time and had dramatic impacts. In partial contrast, the institutions used to exercise control (patterns of agency and governance) remained the same until relatively recently. Other system attributes remained unchanged (e.g., the concept of...

From Premise to Practice: a Critical Assessment of Integrated Water Resources Management and Adaptive Management Approaches in the Water Sector Ecology and Society
Medema, Wietske; ;; McIntosh, Brian S; ;; Jeffrey, Paul J; ; p.j.jeffrey@cranfield.ac.uk.
The complexity of natural resource use processes and dynamics is now well accepted and described in theories ranging across the sciences from ecology to economics. Based upon these theories, management frameworks have been developed within the research community to cope with complexity and improve natural resource management outcomes. Two notable frameworks, Integrated Water Resource Management (IWRM) and Adaptive Management (AM) have been developed within the domain of water resource management over the past thirty or so years. Such frameworks provide testable statements about how best to organise knowledge production and use to facilitate the realisation of desirable outcomes including sustainable resource use. However evidence for the success of IWRM...

A New Paradigm for Adaptive Management Ecology and Society
Felton, Adam; Southern Swedish Forest Research Centre, Swedish University of Agricultural Sciences; adam.felton@slu.se; Rosvall, Ola; Rosvall Forest Consulting AB; Ola.rosvall@gmail.com.
Uncertainty is a pervasive feature in natural resource management. Adaptive management, an approach that focuses on identifying critical uncertainties to be reduced via diagnostic management experiments, is one favored approach for tackling this reality. While adaptive management is identified as a key method in the environmental management toolbox, there remains a lack of clarity over when its use is appropriate or feasible. Its implementation is often viewed as suitable only in a limited set of circumstances. Here we restructure some of the ideas supporting this view, and show why much of the pessimism around AM may be unwarranted. We present a new framework for deciding when AM is appropriate, feasible, and subsequently successful. We thus present a new...

The Interplay of Well-being and Resilience in Applying a Social-Ecological Perspective Ecology and Society
Armitage, Derek; University of Waterloo; derek.armitage@uwaterloo.ca; Charles, Anthony T; Saint Mary's University; Tony.Charles@SMU.CA; Johnson, Derek; University of Manitoba; derek_johnson@umanitoba.ca; Allison, Edward H; The WorldFish Center and the University of East Anglia; e.allison@cgiar.org.
Innovative combinations of social and ecological theory are required to deal with complexity and change in human-ecological systems. We examined the interplay and complementarities that emerge by linking resilience and social well-being approaches. First, we reflected on the limitations of applying ecological resilience concepts to social systems from the perspective of social theory, and particularly, the concept of well-being. Second, we examined the interplay of resilience and well-being concepts in fostering a social-ecological perspective that promises more appropriate management and policy actions. We examined five key points of interplay: (1) the limits of optimization thinking (e.g., maximum sustainable yield), (2) the role of human agency and...

Collective action and the risk of ecosystem regime shifts: insights from a laboratory experiment Ecology and Society
Schill, Caroline; The Beijer Institute of Ecological Economics, The Royal Swedish Academy of Sciences; Stockholm Resilience Centre, Stockholm University; caroline.schill@beijer.kva.se; Lindahl, Therese; The Beijer Institute of Ecological Economics, The Royal Swedish Academy of Sciences; Stockholm Resilience Centre, Stockholm University; therese.lindahl@beijer.kva.se.
Ecosystems can undergo regime shifts that potentially lead to a substantial decrease in the availability of provisioning ecosystem services. Recent research suggests that the frequency and intensity of regime shifts increase with growing anthropogenic pressure, so understanding the underlying social-ecological dynamics is crucial, particularly in contexts where livelihoods depend heavily on local ecosystem services. In such settings, ecosystem services are often derived from common-pool resources. The limited capacity to predict regime shifts is a major challenge for common-pool resource management, as well as for systematic empirical analysis of individual and group behavior, because of the need for extensive preshift and postshift data. Unsurprisingly,...

Improving our ability to manage complex, rapidly changing social-ecological systems is one of the defining challenges of the 21st century. This is particularly crucial if large-scale poverty alleviation is to be secured without undermining the capacity of the environment to support future generations. To address this challenge, strategies that enable judicious management of social-ecological systems in the face of substantive uncertainty are needed. Several such strategies are emerging from the developing body of work on complexity and resilience. We identify and discuss four strategies, providing practical examples of how each strategy has been applied in innovative ways to manage turbulent social-ecological change in South Africa and the broader region:...

Forest Management Approaches for Coping with the Uncertainty of Climate Change: Trade-Offs in Service Provisioning and Adaptability Ecology and Society
Wagner, Sven; Chair of Silviculture, TU-Dresden; wagner@forst.tu-dresden.de; Nocentini, Susanna; Department of Agricultural, Food and Forestry Systems, University of Florence; susanna.nocentini@unifi.it; Huth, Franka; Chair of Silviculture, TU-Dresden; mario@forst.tu-dresden.de; Hoogstra-Klein, Marjanke; Forest and Nature Conservation Policy Group, Wageningen University; Marjanke.Hoogstra@wur.nl.
The issue of rapid change in environmental conditions under which ecosystem processes and human interventions will take place in the future is relatively new to forestry, whereas the provision of ecosystem services, e.g., timber or fresh water, is at the very heart of the original concept of forest management. Forest managers have developed ambitious deterministic approaches to provide the services demanded, and thus the use of deterministic approaches for adapting to climate change seem to be a logical continuation. However, as uncertainty about the intensity of climate change is high, forest managers need to answer this uncertainty conceptually. One may envision an indeterministic approach to cope with this uncertainty; but how the services will be...

Uncertain Emission Reductions from Forest Conservation: REDD in the Bale Mountains, Ethiopia Ecology and Society
Watson, Charlene; London School of Economics and Political Science; c.watson2@lse.ac.uk; Mourato, Susana; London School of Economics and Political Science; s.mourato@lse.ac.uk; Milner-Gulland, E. J.; Imperial College London; e.j.milner-gulland@imperial.ac.uk.
The environmental integrity of a mechanism rewarding Reduced Emissions from Deforestation and Degradation (REDD) depends on appropriate accounting for emission reductions. Largely stemming from a lack of forest data in developing countries, emission reductions accounting contains substantial uncertainty as a result of forest carbon stock estimates, where the application of biome-averaged data over large forest areas is commonplace. Using a case study in the Bale Mountains in Ethiopia, we exemplify the implications of primary and secondary forest carbon stock estimates on predicted REDD project emission reductions and revenues. Primary data estimate area-weighted mean forest carbon stock of 195 tC/ha ± 81, and biome-averaged data reported by the...

Uncertainty in Discount Models and Environmental Accounting Ecology and Society
Ludwig, Donald; University of British Columbia; Ludwig@math.ubc.ca; Brock, William A.; University of Wisconsin-Madison; WBrock@ssc.wisc.edu; Carpenter, Stephen R; University of Wisconsin-Madison; srcarpen@wisc.edu.
Cost-benefit analysis (CBA) is controversial for environmental issues, but is nevertheless employed by many governments and private organizations for making environmental decisions. Controversy centers on the practice of economic discounting in CBA for decisions that have substantial long-term consequences, as do most environmental decisions. Customarily, economic discounting has been calculated at a constant exponential rate, a practice that weights the present heavily in comparison with the future. Recent analyses of economic data show that the assumption of constant exponential discounting should be modified to take into account large uncertainties in long-term discount rates. A proper treatment of this uncertainty requires that we consider returns...

This paper shows, through a numerical example, how to develop portfolios of flood management activities that generate the highest return under an acceptable risk for an area in the central part of the Netherlands. The paper shows a method based on Modern Portfolio Theory (MPT) that contributes to developing flood management strategies. MPT aims at finding sets of investments that diversify risks thereby reducing the overall risk of the total portfolio of investments. This paper shows that through systematically combining four different flood protection measures in portfolios containing three or four measures; risk is reduced compared with portfolios that only contain one or two measures. Adding partly uncorrelated measures to the portfolio diversifies...

Anticipating future risk in social-ecological systems using fuzzy cognitive mapping: the case of wildfire in the Chiquitania, Bolivia Ecology and Society
Devisscher, Tahia; Environmental Change Institute‬, School of Geography and the Environment, University of Oxford; Stockholm Environment Institute; tahia.devisscher@ouce.ox.ac.uk; Boyd, Emily; Department of Geography and Environmental Sciences, University of Reading; Lund University Centre for Sustainability Studies; emily.boyd@reading.ac.uk; Malhi, Yadvinder; Environmental Change Institute‬, School of Geography and the Environment, University of Oxford; yadvinder.malhi@ouce.ox.ac.uk.
Understanding complex social-ecological systems, and anticipating how they may respond to rapid change, requires an approach that incorporates environmental, social, economic, and policy factors, usually in a context of fragmented data availability. We employed fuzzy cognitive mapping (FCM) to integrate these factors in the assessment of future wildfire risk in the Chiquitania region, Bolivia. In this region, dealing with wildfires is becoming increasingly challenging because of reinforcing feedbacks between multiple drivers. We conducted semistructured interviews and constructed different FCMs in focus groups to understand the regional dynamics of wildfire from diverse perspectives. We used FCM modelling to evaluate possible adaptation scenarios in the...

Uncertainty as Information: Narrowing the Science-policy Gap Ecology and Society
Bradshaw, G. A.; National Center for Ecological Analysis and Synthesis (NCEAS) and USDA Forest S; bradshaw@nceas.ucsb.edu; Borchers, Jeffrey G; Department of Forest Science, Oregon State University; borcherj@ucs.orst.edu.
Conflict and indecision are hallmarks of environmental policy formulation. Some argue that the requisite information and certainty fall short of scientific standards for decision making; others argue that science is not the issue and that indecisiveness reflects a lack of political willpower. One of the most difficult aspects of translating science into policy is scientific uncertainty. Whereas scientists are familiar with uncertainty and complexity, the public and policy makers often seek certainty and deterministic solutions. We assert that environmental policy is most effective if scientific uncertainty is incorporated into a rigorous decision-theoretic framework as knowledge, not ignorance. The policies that best utilize scientific findings are defined...

Concerned decision makers increasingly pose questions as to whether current management practices are able to cope with climate change and increased climate variability. This signifies a shift in the framing of climate change from asking what its potential impacts are to asking whether it induces policy failure and unacceptable change. In this paper, we explore the background, feasibility, and consequences of this new framing. We focus on the specific situation in which a social-political threshold of concern is likely to be exceeded as a result of climate change, requiring consideration of alternative strategies. Action is imperative when such a situation is conceivable, and at this point climate change becomes particularly relevant to decision makers. We...

Foghorns to the Future: Using Knowledge and Transdisciplinarity to Navigate Complex Systems Ecology and Society
Cundill, Georgina N. R.; Rhodes University; gcundill@rides.cl; Fabricius, Christo; Rhodes University; c.fabricius@ru.ac.za; Marti, Neus; Autonomous University; neus@amauta.rcp.net.pe.
Complex systems are shaped by cross-scale interactions, nonlinear feedbacks, and uncertainty, among other factors. Transdisciplinary approaches that combine participatory and conventional methods and democratize knowledge to enable diverse inputs, including those from local, informal experts, are essential tools in understanding such systems. The metaphor of a “bridge” to overcome the divide between different disciplines and knowledge systems is often used to advocate for more inclusive approaches. However, there is a shortage of information and consensus on the process, methodologies, and techniques that are appropriate to achieve this. This paper compares two case studies from Peru and South Africa in which community-level assessments...

Fuzzy rule-based system for evaluation of uncertainty transaction in cassava chain REA
GABRIEL FILHO,LUÍS R. A; PIGATTO,GIULIANA A. S.; LOURENZANI,ANA E. B. S..
A fuzzy ruled-based system was developed in this study and resulted in an index indicating the level of uncertainty related to commercial transactions between cassava growers and their dealers. The fuzzy system was developed based on Transaction Cost Economics approach. The fuzzy system was developed from input variables regarding information sharing between grower and dealer on “Demand/purchase Forecasting”, “Production Forecasting” and “Production Innovation”. The output variable is the level of uncertainty regarding the transaction between seller and buyer agent, which may serve as a system for detecting inefficiencies. Evidences from 27 cassava growers registered in the Regional Development Offices of Tupa and Assis, São Paulo, Brazil, and 48 of their...

The spectre of uncertainty in management of exploited fish stocks: The illustrative case of Atlantic bluefin tuna ArchiMer
Fromentin, Jean-marc; Bonhommeau, Sylvain; Arrizabalaga, Haritz; Kell, Laurence T..
The recent overexploitation of East Atlantic and Mediterranean bluefin tuna stock has been well documented in the media where it has become the archetype of overfishing and general mis-management. Beyond the public debate, the crisis also highlighted how the interactions between science and management can change through time according to the awareness of the public opinion. To reflect these issues, the history of Atlantic bluefin tuna overfishing is first described. Then, the major uncertainties that undermine the current scientific advice are summarized and the importance of reducing their impacts by improving knowledge and developing robust scientific framework is considered. The study also discusses how uncertainty was used by different lobbies to...

Global ensemble projections reveal trophic amplification of ocean biomass declines with climate change ArchiMer
Lotze, Heike K.; Tittensor, Derek P.; Bryndum-buchholz, Andrea; Eddy, Tyler D.; Cheung, William W.

M.; Steenbeek, Jeroen; Stock, Charles A.; Verley, Philippe; Volkholz, Jan; Walker, Nicola D.; Worm, Boris.
While the physical dimensions of climate change are now routinely assessed through multimodel intercomparisons, projected impacts on the global ocean ecosystem generally rely on individual models with a specific set of assumptions. To address these single-model limitations, we present standardized ensemble projections from six global marine ecosystem models forced with two Earth system models and four emission scenarios with and without fishing. We derive average biomass trends and associated uncertainties across the marine food web. Without fishing, mean global animal biomass decreased by 5% (+/- 4% SD) under low emissions and 17% (+/- 11% SD) under high emissions by 2100, with an average 5% decline for every 1 degrees C of warming. Projected biomass...
