Multi-level resilience of small-scale fisheries in Baja California, Mexico
Abstract/Contents
- Abstract
- Social-ecological systems (SES) are those that couple the human and natural world through resource exploitation and utilization. They are intricate multi-layered systems that are defined by a complex network of interactions between the resource units, resource systems, governance systems and users within the SES, which can result in a variety of different outcomes. Global climate change is increasingly putting communities in these systems, and the resources they rely on at risk. As such, economically and ecologically important resources within SES are facing stress on two fronts, human extraction, and human induced climate change. Understanding these stressors individually and deciphering the interplay between the two is crucial for informed decision-making to promote resilience of a system and may be the key to the longevity of these SESs. In this dissertation, I explore how current fishing practices and future climate conditions interact across three components of the social-ecological system framework within the context of cooperative fisheries systems of Baja California, Mexico. First, I assess population structure and catch demographics of an economically important fishery resource unit, highlighting the occurrence of multiple recaptures of sub-legal individuals and potential need for bycatch reduction in the face of future climate scenarios. Expanding out, I then adapt a data-poor vulnerability assessment methodology to assess risk of fisheries species within a resource system to multiple climate change stressors. I provide considerations of drivers of risk to climate change between groups of species and highlight the need to account for compounding pressure of multiple climate stressors, multidimensional risk from fishing and climate, and spatial scale of application of the methodology when assessing results for management decisions. Finally, I survey resource users within a Baja fishing cooperative on their knowledge and access to information about climate change and find broad understanding of climate change, spotlight the importance of informal methods of knowledge acquisition, and provide recommendations on the utility of engaging stakeholders in information sharing through social media platforms. In studying multiple components of an SES, I argue co-consideration of fishing and climate impact understanding at every level is crucial for implementation of management schemes for future resilience.
