Item Open Access Institutional and Ecological Interplay for Successful Self-Governance of Community-Based Fisheries(Ecological Economics, 2010) Basurto, Xavier; Coleman, EricThe goal of this paper is to improve our understanding of the role of institutional arrangements and ecological factors that facilitate the emergence and sustainability of successful collective action in small-scale fishing social–ecological systems. Using a modified logistic growth function, we simulate how ecological factors (i.e. carrying capacity) affect small-scale fishing communities with varying degrees of institutional development (i.e. timeliness to adopt new institutions and the degree to which harvesting effort is reduced), in their ability to avoid overexploitation. Our results show that strong and timely institutions are necessary but not sufficient to maintain sustainable harvests over time. The sooner communities adopt institutions, and the stronger the institutions they adopt, the more likely they are to sustain the resource stock. Exactly how timely the institutions must be adopted, and by what amount harvesting effort must be diminished, depends on the ecological carrying capacity of the species at the particular location. Small differences in the carrying capacity between fishing sites, even under scenarios of similar institutional development, greatly affects the likelihood of effective collective action.Item Open Access Marine Ecosystem-Based Management in Mexico: an idea traveling across borders(2010-04-30T19:22:16Z) Villanueva-Aznar, Hilda CristinaEcosystem-based management (EBM) has gained acceptance around the world as an integrated approach to management based on science that considers the entire ecosystem, including humans. I analyze two implementation projects of EBM in the Gulf of California (GC): one focused on shrimp fisheries and the other on artisanal fisheries, both funded by The Packard Foundation. Using semi-structured interviews of key informants, I try to understand how the idea of EBM for fisheries management emerged in the GC, how is this concept understood in that region, and the challenges that this new management scheme has faced in the Mexican context. I discuss that this idea has surged as a response to the Mexican fisheries crises as well as the external influence from donors; that it is a concept regarded to be too skewed towards science and to have an environmentalist agenda; and how the challenges for EBM implementation in the Mexican context are mostly related to governance and institutional arrangements.Item Open Access Participation for Conservation: The Role of Social Capital in Multi-level Governance of Small-scale Fisheries(2015) Nenadovic, MatejaThe need for effective multi-level governance arrangements is becoming increasingly apparent because of the high functional interdependencies between biophysical and socioeconomic factors in the realm of natural resource governance. Such arrangements provide a basis for the exchange, discussion, and deliberation of information, knowledge, and data across diverse user groups and entities. Multi-level governance is operationalized by using a microinstitutional analysis that links decision-making arenas across three distinct levels: operational, collective-choice, and constitutional. Within this context, I argue that the effectiveness and success of actors' participatory processes across these three levels depend on the amount of social capital among actors within the governance system. I assessed the concept of social capital using two different models: (1) a structural approach focused on resources embedded within an individual's network, and (2) a combined structural-cultural approach that incorporates various aspects of group membership with relations of trust, rules, and norms. To explore the effects of social capital on participatory processes related to the implementation and management of natural resources, I analyzed different small-scale fisheries governance regimes from the Gulf of California, Mexico. I collected data using surveys (n=371), interviews (n=82), and participant observation techniques conducted among the residents of four small-scale fishing communities that live adjacent to marine protected areas along the Baja California, Mexico, peninsula. Data analysis included both quantitative (logit regression model), and qualitative (narrative analysis) approaches. Overall, my results suggest that both social capital models reveal the multidimensional nature of social capital where none of its individual types form a consistent and statistically significant relationship with the six outcomes that I measured. However, these types are related in different ways to fishers engagement in participatory processess across the three levels. The extent of fishers' engagement in participatory processess across different levels was not high. Qualitative analysis revealed that participatory processes related to fisheries conservation and management, although present do not reach their full potential and are stymied by a historical context and a lack of general participatory culture.
Item Open Access Using Social and Ecological Data to Identify Trends in Three Marine Protected Areas in the Gulf of California(2017-04-18) Starks, CaitlinMarine protected areas (MPAs) have become an increasingly common conservation tool in marine environments, yet few studies have focused on impacts to fisheries and communities in addition to ecological impacts. In this study, I draw on multiple data sources including interviews with MPA managers, ecological monitoring data, and fisheries landing reports, in a more holistic approach to understanding how MPAs interact with social and ecological systems. Using qualitative and quantitative analyses, I aim to illuminate social, ecological and fishery trends surrounding Cabo Pulmo National Park, Bahia de Loreto National Park, and Espiritu Santo Archipelago National Park in the southern Gulf of California, Mexico. Findings from this study show that trends reflected in different data sets can vary widely within and between MPAs, and further research should focus on disentangling the connections between social, ecological and fisheries data in MPA evaluations.
