- ItemExploring determinants for the implementation of mixed TURF-aquaculture systems(2019) Sepulveda, Cristian; Rivera, Antonella; Gelcich, Stefan; Stotz, Wolfgang B.Territorial use rights in fisheries (TURFs) have been highlighted as a means to deter the race for fish. Nevertheless, in many situations TURFs are not able to meet all their goals, jeopardizing their continuity. Here we explore one of several innovations on TURFS, mixed TURF-aquaculture systems, which can help overcome the challenges of maintaining sustainable socio-ecological systems. We analyzed the history of mixed TURF and small-scale aquaculture systems in Chile, particularly 8 recent learning platforms in the Coquimbo region. Additionally, we assessed the impact of 6 variables, from multiple spheres, on the implementation of mixed TURF-aquaculture systems. Despite low values in several variables, 75% of the learning platforms managed to implement aquaculture systems and 38% have been successful in developing monitoring efforts. Social capital was key in the implementation of the mixed systems. By investing in social capital policy makers can contribute to the successful implementation of mixed TURF-aquaculture systems, thus promoting a livelihood diversification strategy for fishing communities that encompasses the economic benefits of aquaculture with the socio-ecological benefits of TURFs. However, their development and enabling conditions must be monitored to embrace their synergies. (C) 2019 Elsevier B.V. All rights reserved.
- ItemExploring relationships between gender and collective action in artisanal fisher associations of Central Chile(2022) Vargas Poulsen, Camila; Rivera, Antonella; Ortiz, Veronica; Carlos Castilla, Juan; Estevez, Rodrigo A.; Reyes-Mendy, Francisca; Gelcich, Stefanfisher associations have experienced a shift towards gender inclusivity over the past decade. We used the social-ecological systems framework developed by Elinor Ostrom to explore relationships between gender and collective action. Questionnaires were used to determine (1) motivations to join an association, (2) socio-demographic information, (3) perceptions on key collective action dimensions around leadership and norms within the association, and (4) perceived social performance. Surveys targeted artisanal fisher associations in Chile with varying gender compositions: exclusively male members, exclusively female members, mixed-gender led by a man, and mixed -gender led by a woman. Our results show that women and men have distinct motivations to join an association. Women are primarily motivated by a sense of belonging, while men are mainly motivated by the possibility of an increase in income. Furthermore, associations comprised of women displayed higher valuations on leadership, entrepreneurship, and participation in activities. This likely led to the significantly higher performance of associations that incorporated women (either women-only or mixed gender) in efficiency (30.1%- 40.3% higher) and cooperation (13.8%-30. 8% higher). Our results extend the social-ecological systems framework towards understanding the role of gender in collective action for fisheries management and specifically contribute to build knowledge and implement novel policy which considers gender in artisanal fisheries in Chile.
- ItemExploring the adaptive capacity of the mussel mariculture industry in Chile(ELSEVIER, 2020) San Martin, Valeska A.; Vasquez Lavin, Felipe; Ponce Oliva, Roberto D.; Paz Lerdon, Ximena; Rivera, Antonella; Serramalera, Leticia; Gelcich, StefanSocieties have adapted to climate and environmental variability throughout history. However, projected climate change poses multiple risks to mariculture because of the increased frequency of environmental threats that lie outside the realm of present day experience. Adaptive capacity evaluated in this study is a characteristic that would reflect mariculture industries ability to anticipate and respond to these changes, and to minimize, cope with, and recover from the consequences and take advantage of new opportunities arising from change. Drawing on a survey to 90 mussel mariculture companies in Chiloe-Chile, we have characterized the way the industry has adapted and recovered from specific stressors in productive capacity, namely; reduced mussel growth rates and reduced larval supply. We additionally assess determinants of the mussel industry's willingness to invest in building capacity to anticipate changes through analysing mussel aquaculture companies' assets to draw upon in times of need (capital; access to credit), the flexibility to change strategies, the companies' perception of the industry's social organization to act collectively (social capital), and their response to hypothetical scenarios regarding shocks in productive capacity. Results show heterogeneity in production decisions when facing environmental stressors. Results also show that the industry adapts in heterogeneous ways and that financial assets and social capital drive willingness to invest in adaptive capacity. Understanding past adaptation strategies and the willingness of the industry to invest in anticipating stressors allows us to begin exploring the consequences of new stressors. Importantly, as Chile and other countries are developing adaptation plans to face the multiple stressors of climate change, information about stakeholders' existing adaptation strategies and their determinants is becoming a critical bottleneck to inform these processes and assure they are in line with stakeholder needs and interest. While we use the Chilean mussel industry as a working example, the approach presented can inform other countries/regions wishing to explore the adaptive capacity of their aquaculture sectors.
