Adaptive Co-management Networks: a Comparative Analysis of Two Fishery Conservation Areas in Sweden Ecology and Society
Rova, Carl; Division of Social Science/Political Science Unit, Luleå University of Technology, Sweden; carl.rova@ltu.se.
Co-management constitutes a certain type of institutional arrangement that has gained increased attention among both policy makers and researchers involved in the field of natural resource management. Yet the concept of co-management is broad, and our knowledge about how different kinds of management structures affect the ability to deal with challenges pertinent to the commons is limited. One of these challenges is to foster an adaptive management process, i.e., a process in which rules are continuously revised and changed according to what is known about the ecological system. We aim to address the relationship between different kinds of co-management structures and adaptive management. To this end, we conducted a comparative case study of two Fishery...

Can Properties of Labor-Exchange Networks Explain the Resilience of Swidden Agriculture? Ecology and Society
Downey, Sean S.; Stanford University; ssdowney@stanford.edu.
Despite the fact that swidden agriculture has been the subject of decades of research, questions remain about the extent to which it is constrained by demographic growth and if it can adapt to environmental limits. Here, social network analysis is used to analyze farmer labor-exchange networks within a chronosequence of five Q’eqchi’ Maya villages where swidden agriculture is used. Results suggest that changes in land-use patterns, network structure, reciprocity rates, and levels of network hierarchy may increase the resilience of these villages to changes in the forest’s agricultural productivity caused by ongoing agricultural activity. I analyze the suitability of subsistence- versus market-oriented agricultural labor for...

Clustering of water bodies in unpolluted and polluted environments based on Escherichia coli phylogroup abundance using a simple interaction database Genet. Mol. Biol.
Stoppe,Nancy de Castro; Silva,Juliana Saragiotto; Torres,Tatiana Teixeira; Carlos,Camila; Hachich,Elayse Maria; Sato,Maria Inês Zanoli; Saraiva,Antonio Mauro; Ottoboni,Laura Maria Mariscal.
Different types of water bodies, including lakes, streams, and coastal marine waters, are often susceptible to fecal contamination from a range of point and nonpoint sources, and have been evaluated using fecal indicator microorganisms. The most commonly used fecal indicator is Escherichia coli, but traditional cultivation methods do not allow discrimination of the source of pollution. The use of triplex PCR offers an approach that is fast and inexpensive, and here enabled the identification of phylogroups. The phylogenetic distribution of E. coli subgroups isolated from water samples revealed higher frequencies of subgroups A1 and B2(3) in rivers impacted by human pollution sources, while subgroups D1 and D2 were associated with pristine sites, and...

Comigrants and friends: informal networks and the transmission of traditional ecological knowledge among seminomadic pastoralists of Gujarat, India Ecology and Society
Patel, Hanoz H. R.; The Maharaja Sayajirao University of Baroda, Vadodara, Gujarat, India; write2hanoz@gmail.com; Rubio-Campillo, Xavier; Barcelona Supercomputing Center (BSC), Barcelona, Spain; xavier.rubio@bsc.es.
Previous research has shown that social organization may affect the distribution of traditional ecological knowledge (TEK) within local communities of natural resource users in multiple ways. However, in this line of research the potential role of informal relationships has mostly been overlooked. In this article, we contribute toward filling this research gap by studying how two types of informal relationships, namely migration partnership and friendship, affect the distribution of TEK within a community of seminomadic pastoralists from the Kutch area, Gujarat, India. Using social network analysis, we map three networks, migration, men friendship, and women friendship, and compare with similarity-based quantitative approaches the clusters extracted from...

Prell, Christina; University of Sheffield; c.prell@sheffield.ac.uk; Reed, Mark; Aberdeen Centre for Environmental Sustainability and Centre for Planning and Environmental Management School of Geosciences, University of Aberdeen ; m.reed@abdn.ac.uk; Racin, Liat; Department of Geography, King's College London ; Liat.Racin@kcl.ac.uk; Hubacek, Klaus; Department of Geography, University of Maryland; Hubacek@umd.edu.
What is social structure, and how does it influence the views and behaviors of land managers? In this paper, we unpack the term "social structure" in the context of current research on institutions, social networks, and their role(s) in resource management. We identify two different kinds of structure, formal and informal, and explore how these link to views of land management and management practice. Formal structures refer to intentionally designed organizations that arise out of larger institutional arrangements; informal ones refer to social networks, based on the communication contacts individuals possess. Our findings show significant correlations between respondents' views regarding land management and their social networks; it is these informal...

Does size matter? An assessment of quota market evolution and performance in the Great Barrier Reef fin-fish fishery Ecology and Society
Innes, James; CSIRO Oceans and Atmospheres Flagship; James.Innes@csiro.au; Little, L. Richard; CSIRO Oceans and Atmospheres Flagship; Rich.Little@csiro.au.
In fisheries managed using individual transferable quotas (ITQs) it is generally assumed that quota markets are well-functioning, allowing quota to flow on either a temporary or permanent basis to those able to make best use of it. However, despite an increasing number of fisheries being managed under ITQs, empirical assessments of the quota markets that have actually evolved in these fisheries remain scarce. The Queensland Coral Reef Fin-Fish Fishery (CRFFF) on the Great Barrier Reef has been managed under a system of ITQs since 2004. Data on individual quota holdings and trades for the period 2004-2012 were used to assess the CRFFF quota market and its evolution through time. Network analysis was applied to assess market structure and the nature of...

Dynamics of the botanical knowledge of the Laklãnõ-Xokleng indigenous people in Southern Brazil Acta Botanica
Heineberg,Marian Ruth; Hanazaki,Natalia.
ABSTRACT We analyzed the botanical knowledge of the Laklãnõ-Xokleng people in the Ibirama Laklãnõ Indigenous Territory. They are the last remnant of this ethnicity living in a unitary socio-political organization. The objective was to investigate the dynamics, distribution and transmission of botanical information. We interviewed 112 people in two villages about known and used plants. Data were collected through structured socioeconomic questionnaires, free lists and walk-in-the-woods tours. Data were analyzed using descriptive statistics and metrics of social network analysis. Of the 314 plants mentioned in the interviews, 77 % were currently used, 15 % were used in the past, and 8 % were known but never used. Men cited more plants than women. We found no...

Effects of farmer social status and plant biocultural value on seed circulation networks in Vanuatu Ecology and Society
Seed circulation among farmers, which is embedded in composite social networks, is a key process in the dynamics of seed systems that shape crop diversity. We analyzed the daily circulation of biological objects, i.e., cultivated plants (31 species, 284 landraces), within a community of first-generation migrants (16 households, 30 persons) living on the island of Vanua Lava in the South Pacific archipelago nation of Vanuatu. By combining participant observation, ethnobiological inventories, and social network analysis, we investigated how farmer social status and plant biocultural value affect plant circulation. Plant biocultural value was estimated by referring to their local classification according to uses, cultivation practices, growing environments,...

Evaluating the implementation process of LEADER in Romania AgEcon
Marquardt, Doris; Mollers, Judith.
LEADER supports integrated rural regional development. The programme is characterized by a participatory and bottom-up approach, public-private partnerships, multi-sectoral regional development strategies and innovation. An obligatory Common Monitoring and Evaluation Framework (CMEF) was set up for evaluating EU interventions. The CMEF builds upon sets of common indicators and evaluation questions. Romania, where LEADER is currently introduced, has set national priorities for the programme implementation. For assessing the impact of LEADER in Romania meaningfully, an extension of the CMEF is needed. This paper, identifies and suggests appropriate indicators. Social Network Analysis is proposed as a tool for investigating intangible outcomes of LEADER in a...

Reducing Emissions from Deforestation and Forest Degradation (REDD+) is a priority issue for forest and climate policy in Indonesia, and REDD+ policy-making activity has been characterized by considerable public consultation. Despite this engagement, discussions on REDD+ in Indonesia are reported to have remained top-down, a disconcerting pattern when adaptive governance and transformational change require cross-scale and cross-sectoral communication. Explicitly modeling the patterns of information exchange related to REDD+ can clarify these claims and help identify potential barriers to the transformational change needed to implement REDD+. We used data obtained through semistructured and structured interviews held in 2011 with representatives from a...

Interhousehold variability and its effects on seed circulation networks: a case study from northern Cameroon Ecology and Society
We present a detailed ethnographic case study of sorghum seed acquisitions in a smallholder farming society in northern Cameroon. The effects of variability in household demographics and socioeconomic status on observed patterns of seed provisioning are explored alongside other variables such as age and gender. Our data set comprised 223 seed acquisition events. Independence tests (Pearson’s chi-square and Fisher’s exact tests) were carried out to test for significant dependencies between individual- or household-level characteristics and properties of seed acquisition events (categories of seed source, social relationship of exchange, and type of landrace). Results indicate that wealth is a structuring factor of the local seed...

Migrant farmers as information brokers: agroecosystem management in the transition zone of Ghana Ecology and Society
Isaac, Marney E.; Department of Physical and Environmental Sciences and Center for Critical Development Studies, University of Toronto Scarborough; Department of Geography, University of Toronto; marney.isaac@utoronto.ca; Anglaaere, Luke C. N.; Forestry Research Institute of Ghana;; Akoto, Daniel S.; Faculty of Renewable Natural Resources, Kwame Nkrumah University of Science and Technology;; Dawoe, Evans; Faculty of Renewable Natural Resources, Kwame Nkrumah University of Science and Technology;.
Environmentally induced farmer migration is an important livelihood strategy, yet little is known of the effects on the destination region agroecosystem information networks and management practices. In the forest-savanna transition zone (Brong Ahafo Region) of Ghana, where migration from northern regions (migrant) and from neighboring regions (settler) is active, we chart the role of migrant famers and the type of agroecosystem management practices embedded in information networks using a social networks approach. Based on empirical network data from 44 respondents across three communities, we illustrate a diffuse information network, with variable tie frequency between settlement categories (local, settler, or migrant) of farmers. The cohesion of this...

Misurare la buona governance dei territori rurali: un possibile set di indicatori AgEcon
Franceschetti, Giorgio; Da Re, Riccardo; Secco, Laura.
Il significato più comune e condiviso del termine governance si riferisce alla capacità della pubblica amministrazione di gestire e dirigere network, coinvolgendo attori pubblici e privati di varia natura in processi politico-decisionali, promuovendo il dialogo, la condivisione di responsabilità, la partecipazione e il coordinamento di molti attori a molti livelli. Modalità organizzative e d’interazione tra i vari soggetti che siano in grado di garantire una “buona governance”, soprattutto in relazione all’uso delle risorse naturali e a alla valorizzazione del capitale sociale, stanno diventando fattori chiave nello sviluppo rurale. Il concetto di “buona governance” riflette la crescente domanda espressa dalla società civile di maggior partecipazione dei...

Multistakeholder environmental governance in action: REDD+ discourse coalitions in Tanzania Ecology and Society
Rantala, Salla; University of Helsinki; University of Eastern Finland; salla.rantala@helsinki.fi; Di Gregorio, Monica ; University of Leeds; M.DiGregorio@leeds.ac.uk.
Balancing interests to achieve legitimate and effective policies is a primary and pressing challenge in countries’ efforts to prepare their national reducing emissions from deforestation and forest degradation (REDD+) strategies. Using Tanzania as a country case, we investigated the most polarizing policy discourses and assessed the influence of competing discourse coalitions on the drafting of the national REDD+ strategy. We combined discourse and social network analysis to identify discourse coalitions and assess their influence. The findings indicate that the national REDD+ strategy largely reflects the positions of the discourse coalition that is controlled by powerful state actors who support central control of REDD+ financial mechanisms....

National REDD+ policy networks: from cooperation to conflict Ecology and Society
Brockhaus, Maria; Center for International Forestry Research; m.brockhaus@cgiar.org; Di Gregorio, Monica; University of Leeds, Sustainability Research Institute; m.digregorio@leeds.ac.uk.
Reducing emissions from deforestation and forest degradation (REDD+) is a financial mechanism aimed at providing incentives to reduce carbon emissions from forests and enhance carbon stocks. In most forest-rich developing countries, policy actors, i.e., state and nonstate as well as international and national, are designing national REDD+ policies. Actors’ interests and beliefs shape patterns of interactions, ranging from cooperation to conflict, and these interactions influence a country’s direction and progress in REDD+ policy formulation and implementation. We used a comparative policy network approach to analyze the power structures in national REDD+ policy domains in seven countries. We drew on the typology of power structures...
