Legitimacy, Adaptation, and Resilience in Ecosystem Management Ecology and Society
Cosens, Barbara A; University of Idaho College of Law; bcosens@uidaho.edu.
Ecologists have made great strides in developing criteria for describing the resilience of an ecological system. In addition, expansion of that effort to social-ecological systems has begun the process of identifying changes to the social system necessary to foster resilience in an ecological system such as the use of adaptive management and integrated ecosystem management. However, these changes to governance needed to foster ecosystem resilience will not be adopted by democratic societies without careful attention to their effect on the social system itself. Delegation of increased flexibility for adaptive management to resource management agencies must include careful attention to assuring that increased flexibility is exercised in a manner that is...

Influencing adaptation processes on the Australian rangelands for social and ecological resilience Ecology and Society
Marshall, Nadine A.; CSIRO, Ecosystem Sciences and Climate Adaptation Flagship; School of Earth and Environment Sciences, James Cook University; nadine.marshall@csiro.au; Stokes, Chris J.; CSIRO, Ecosystem Sciences and Climate Adaptation Flagship; chris.stokes@csiro.au.
Resource users require the capacity to cope and adapt to climate changes affecting resource condition if they, and their industries, are to remain viable. Understanding individual-scale responses to a changing climate will be an important component of designing well-targeted, broad-scale strategies and policies. Because of the interdependencies between people and ecosystems, understanding and supporting resilience of resource-dependent people may be as important an aspect of effective resource management as managing the resilience of ecological components. We refer to the northern Australian rangelands as an example of a system that is particularly vulnerable to the impacts of climate change and look for ways to enhance the resilience of the system....

Learning in Support of Governance: Theories, Methods, and a Framework to Assess How Bridging Organizations Contribute to Adaptive Resource Governance Ecology and Society
Crona, Beatrice I; Stockholm Resilience Centre, Stockholm University, Sweden; Center for the Study of Institutional Diversity, Arizona State University, Tempe, Arizona, USA; beatrice.crona@stockholmresilience.su.se; Parker, John N; National Center for Ecological Analysis and Synthesis, Santa Barbara, California, USA; Barrett Honors College, Arizona State University, Tempe, Arizona, USA; parker@nceas.ucsb.edu.
Humanity faces increasingly intractable environmental problems characterized by high uncertainty, complexity, and swift change. Natural resource governance must therefore involve continuous production and use of new knowledge to adapt to highly complex, rapidly changing social-ecological systems to ensure long-term sustainable development. Bridging and boundary organizations have been proposed as potentially powerful means of achieving these aims by promoting cooperation among actors from the science, policy, and management sectors. However, despite substantial investments of time, capital, and human resources, little agreement exists about definitions and measures of knowledge production and how this is achieved in bridging organizations and there is...

Theorizing benefits and constraints in collaborative environmental governance: a transdisciplinary social-ecological network approach for empirical investigations Ecology and Society
Robins, Garry; Melbourne School of Psychological Sciences, University of Melbourne; garrylr@unimelb.edu.au; McAllister, Ryan R. J.; CSIRO; ryan.mcallister@csiro.au; Guerrero, Angela M.; Australian Research Council Centre of Excellence for Environmental Decisions, University of Queensland; School of Biological Sciences, University of Queensland; a.guerrero@uq.edu.au; Crona, Beatrice; Global Economic Dynamics and the Biosphere, Royal Swedish Academy of Sciences; Stockholm Resilience Centre, Stockholm University; beatrice.crona@su.se; Lubell, Mark; Department of Environmental Science and Policy, University of California at Davis; mnlubell@ucdavis.edu.
When environmental processes cut across socioeconomic boundaries, traditional top-down government approaches struggle to effectively manage and conserve ecosystems. In such cases, governance arrangements that foster multiactor collaboration are needed. The effectiveness of such arrangements, however, depends on how well any ecological interdependencies across governed ecosystems are aligned with patterns of collaboration. This inherent interdisciplinary and complex problem has impeded progress in developing a better understanding of how to govern ecosystems for conservation in an increasingly interconnected world. We argue for the development of empirically informed theories, which are not only able to transcend disciplinary boundaries, but are also...

Achieving social-ecological fit through bottom-up collaborative governance: an empirical investigation Ecology and Society
Guerrero, Angela M; Australian Research Council Centre of Excellence for Environmental Decisions, University of Queensland; School of Biological Sciences, University of Queensland; a.guerrero@uq.edu.au; McAllister, Ryan R. J.; Commonwealth Scientific and Industrial Research Organisation; ryan.mcallister@csiro.au; Wilson, Kerrie A; Australian Research Council Centre of Excellence for Environmental Decisions, University of Queensland; School of Biological Sciences, University of Queensland; k.wilson2@uq.edu.au.
Significant benefits can arise from collaborative forms of governance that foster self-organization and flexibility. Likewise, governance systems that fit with the extent and complexity of the system under management are considered essential to our ability to solve environmental problems. However, from an empirical perspective the fundamental question of whether self-organized (bottom-up) collaborative forms of governance are able to accomplish adequate fit is unresolved. We used new theory and methodological approaches underpinned by interdisciplinary network analysis to address this gap by investigating three governance challenges that relate to the problem of fit: shared management of ecological resources, management of interconnected ecological...

The Influence of Forums and Multilevel Governance on the Climate Adaptation Practices of Australian Organizations Ecology and Society
Bates, Lorraine E.; CSIRO Social and Economic Sciences Program; lbates@iinet.net.au; Green, Melissa; CSIRO Social and Economic Sciences Program; melissa.green@csiro.au; Leonard, Rosemary; CSIRO Social and Economic Sciences Program; rosemary.leonard@csiro.au; Walker, Iain; CSIRO Social and Economic Sciences Program; Iain.A.Walker@csiro.au.
To date, there are few regulations and policies relating to climate change in Australia. Uncertainty about the timing, structure, and potential impact of proposed legislation such as a national carbon abatement scheme, is leading to planning delays across the country. To assist with these policy uncertainties, organizations can embed themselves in multilevel governance frameworks that inform, structure, and facilitate strategic development, planning, and action. As part of these networks, organizational representatives also engage in formal and informal forums, a type of interorganizational relationship, which can include industry task forces, policy development committees, interagency groups, and specific climate change committees. Forums constitute an...

Multiple pathways to sustainability in the city: the case of San Juan, Puerto Rico Ecology and Society
I examined the multiple visions of the future of the city that can emerge when city actors and organizations reconfigure themselves to address sustainability. In various cities worldwide, novel ideas, initiatives, and networks are emerging in governance to address social and ecological conditions in urban areas. However, cities can be contested spaces, bringing a plurality of actors, network configurations, preferences, and knowledge that shape the politics over desirable pathways for future development. I used the knowledge-action systems analysis (KASA) approach to examine the frames and knowledge systems influencing how different actors involved in the land governance network of the city of San Juan constructed visions for the future of the city....

The Practice of Transboundary Decision Making on the Incomati River: Elucidating Underlying Factors and their Implications for Institutional Design Ecology and Society
Slinger, Jill H.; Delft University of Technology; j.h.slinger@tudelft.nl; Hilders, Marianne; DHV B.V. (Adviesgroep Water, Natuur en Ruimte); Marianne.Hilders@DHV.nl; Juizo, Dinis; Eduardo Mondlane University; juizo@hotmail.com.
The Incomati River Basin is shared by Mozambique, South Africa, and Swaziland. In August 2002, the groundbreaking “Tripartite Interim Agreement on Water Sharing of the Maputo and Incomati Rivers” (the IncoMaputo agreement) was signed. Following reports that the use, availability, and adequacy of information posed problems for future decision making on this transboundary river, the Delft University of Technology initiated a 6-month study in 2003 in which 25 southern African researchers and officials were interviewed. The Joint Incomati Basin Study (Phase I from 1992–1995, and Phase II from 2000–2001) formed a central component in the investigation, because it was viewed by the parties involved as a successful...

Networking for conservation: social capital and perceptions of organizational success among land trust boards Ecology and Society
Ruseva, Tatyana B.; Appalachian State University; rusevatb@appstate.edu; Farmer, James R.; Indiana University; jafarmer@indiana.edu; Chancellor, Charles; Clemson University; hchance@clemson.edu.
As an important component in collaborative natural resource management and nonprofit governance, social capital is expected to be related to variations in the performance of land trusts. Land trusts are charitable organizations that work to conserve private land locally, regionally, or nationally. The purpose of this paper is to identify the level of structural and cognitive social capital among local land trusts, and how these two types of social capital relate to the perceived success of land trusts. The analysis integrates data for land trusts operating in the U.S. south-central Appalachian region, which includes western North Carolina, southwest Virginia, and east Tennessee. We use factor analysis to elicit different dimensions of cognitive social...

New Insights into the Ecology and Physiology of Methanomassiliicoccales from Terrestrial and Aquatic Environments ArchiMer
Cozannet, Marc; Borrel, Guillaume; Roussel, Erwan; Moalic, Yann; Allioux, Maxime; Sanvoisin, Amandine; Toffin, Laurent; Alain, Karine.
Members of the archaeal order Methanomassiliicoccales are methanogens mainly associated with animal digestive tracts. However, environmental members remain poorly characterized as no representatives not associated with a host have been cultivated so far. In this study, metabarcoding screening combined with quantitative PCR analyses on a collection of diverse non-host-associated environmental samples revealed that Methanomassiliicoccales were very scarce in most terrestrial and aquatic ecosystems. Relative abundance of Methanomassiliicoccales and substrates/products of methanogenesis were monitored during incubation of environmental slurries. A sediment slurry enriched in Methanomassiliicoccales was obtained from a freshwater sample. It allowed the...

Water quality criteria and monitoring for marine mollusc culture : the French experience ArchiMer
Heral, Maurice; Berthome, Jean-paul.
The impact of the main parameters of water quality which act on the life history of molluscs are presented. Two types of parameters are examined: the first are the physical-chemical parameters as temperature, salinity, turbidity, oxygen concentrations. They can be modified by perturbations directly related to human activities such as management of physical operations, e.g. constructions of dams, dredging for channels or for extraction of materials. Particular attention is given to inputs of nutrients with as consequences eutrophication and depletion of oxygen causing anoxie conditions. Attention will he focussed on some phytoplankton species like Gyrodinium aurelum which can cause mortalities in mollusc shellfish. The action of the main pollutants...

Cournot Competition on a Network of Markets and Firms AgEcon
Ilkilic, Rahmi.
Suppose markets and firms are connected in a bi-partite network, where firms can only supply to the markets they are connected to. Firms compete a la Cournot and decide how much to supply to each market they have a link with. We assume that markets have linear demand functions and firms have convex quadratic cost functions. We show there exists a unique equilibrium in any given network of firms and markets. We provide a formula which expresses the quantities at an equilibrium as a function of a network centrality measure.

Expectations, Experiences, Trust in the Case of Short Circuit Food Supply Networks AgEcon
Martino, Gaetano; Fritz, Melanie.
Farmers Markets are receiving an increasing attention by both food chains actors and social scientists. Economic and sociological studies are contributing to the comprehension of these forms of exchange. Both consumers and producers are fostering their expectations about the renewal of a mode of exchange which sustained local production‐ consumptions linkages. The main economic function of these organizational structures seems to be the reduction of the price paid by the consumers and the enhancements of allocation of farm products. The basic interpretation of these forms of exchange focuses on market structure, nonetheless the exchange relationships seems to emphasize several dimensions, including economic and cultural aspects. The objective of the paper...

Disaggregating Mexican Migrant Networks: The Parts are Greater Than the Whole AgEcon
Winters, Paul C.; Stecklov, Guy; Davis, Benjamin.
In this paper, we explore the role of social networks in the migration decision focusing on the distinct influence networks have on domestic and international migration. The analysis focuses particular attention on the composition of migrant networks in order to improve our understanding of how network composition influences the migration decision. Using data from rural Mexico, we consider migration in a multiple choice context allowing for the possibility that individuals can migrate within Mexico for agricultural and non-agricultural employment as well as to the United States. Our principle result is that the parts are greater than the whole; using disaggregated measures of social networks highlights the complexity of network effects on migration...

From Contracts to Networks: New Directions in the Study of Governance of Agro‐Food‐Energy Networks AgEcon
Zylbersztajn, Decio.
The debate about the governance of complex systems of production represents a rich branch of the literature of applied organization theory. The particular application to agro‐related networks is a relevant example since agriculture plays new roles in modern society. The core of the analysis is centered in the rationale for allocation of residual decision rights and distribution of the rights regarding the value created. Contributions based in transaction cost economics, resource‐based view, dynamic competences, and incomplete contract theory explore different dimensions related to the allocation of property rights. The question of how joint strategies are defined, and how value added (or subtracted) is shared among network players is still relevant....

Supply Chain and Network Performance: Metrics for Profitability, Productivity, and Efficiency AgEcon
Weaver, Robert D..
The architecture of the firm involves determination of a boundary that encompasses the functions managed by the firm. The past decade has seen substantial reorganization of firms where vertical or horizontal integration has been unbundled into weaker forms of collaborations including value chains and networks. This observation has forced a re-conceptualization of the boundaries of the firm to incorporate such collaborations. These collaborations are virtual and highly dynamic. They emerge and persist when two conditions are met. First, they must enable generation of greater value than might be attained through independent operation and anonymous transactions through markets. Second, the resulting growth must be shared with members in a way that retains...

Social Responsibility as a Driver for Local Sustainable Development AgEcon
Costantino, Elena; Marchello, Maria Paola; Mezzano, Cecilia.
The increased interconnection among local and global players induced by globalization, as well as the need for a complete application of the “subsidiarity principle”, calls for a re-thinking of the “corporate social responsibility” concept. This new concept broadens the perspective of the single company interacting with its own stakeholders in relation to specific social and environmental impacts, to a network of organizations, with different aims and natures, collaborating on relevant sustainability issues. In this paper, the authors will provide a definition of “Territorial Social Responsibility”, sustaining the multi-stakeholder approach as a driver toward local sustainable development. Firstly, theoretical approaches to sustainable development at the...

R&D Collaboration Networks in Mixed Oligopoly AgEcon
Zikos, Vasileios.
We develop a model of endogenous network formation in order to examine the incentives for R&D collaboration in a mixed oligopoly. Our analysis reveals that the complete network, where each firm collaborates with all others, is uniquely stable, industry-profit maximizing and efficient. This result is in contrast with earlier contributions in private oligopoly where under strong market rivalry a conflict between stable and efficient networks is likely to occur. A key finding of the paper is that state-owned enterprises may be used as policy instruments in tackling the potential conflict between individual and collective incentives for R&D collaboration.
