Appendix 1:
Indicators developed for the measurement of the variables.
| Variable | Theoretical statement of CA | Source: adapted from | Ordinal value description |
| Clarity of system boundaries (RS2) | Clear spatial boundaries increase likelihood of CA. Easier to tell who is in or out, and to monitor | Ostrom 1990; Cox et al. 2010; Basurto et al. 2013; Trimble and Berkes 2015; London et al. 2017 | Clear: geographic and social boundaries are well-defined, making feasible to identify who is in or out Partially: geographic and social boundaries are not clear enough, but some structures (e.g. buoys) and limitations remain identifying who is in or out Unclear: unclear geographical and social boundaries make infeasible to identify who is in or out |
| Size of resource system (RS3) | Larger areas provide enough resource availability, increasing the likelihood of CA | Ostrom 2009 | Small: Perception of a small-size resource system Medium: Perception of a medium-size resource system Large: Perception of a large-size resource system |
| Smaller areas are easier to monitor as transaction costs decrease, increasing the likelihood of CA. Larger areas are difficult to monitor as transaction costs increase, decreasing the likelihood of CA | Ostrom 2009 | Small: Perception of a small-size resource system Medium: Perception of a medium-size resource system Large: Perception of a large-size resource system | |
| Operational rules (GS5) | Formal rules chosen by local actors are implemented, increasing the likelihood of CA | Basurto et al. 2013 | Present: Rules are operating in a maximum or total degree Partially: Rules are still operating at certain degree Absent: Rules are operating in a minimum or null degree |
| Collective-choice rules (GS6) | Allowance of local actors (i.e. fishers using multiple gear types) to participate in designing or modifying rules increases the likelihood of CA | Ostrom 1990; Cox et al. 2010 | Low: Participation of local actors in decision making is minimal or null Medium: Participation of local actors in decision making is moderate High: Participation of local actors in decision making is maximal |
| Monitoring and sanctioning (GS8) | Presence of monitoring and graduated sanctioning mechanisms facilitate rule compliances and increases the likelihood of CA | Ostrom 1990; Pomeroy et al. 2001 | Absence: Minimal efforts are taken to patrol illegal activities within the AMPR, and to apply graduated sanctions for assuring rule compliance. Partially: Efforts are taken but not enough to patrol illegal activities within the AMPR. Enforcement and gradual sanctions mechanisms are sometimes applied with actors that disrespect rules. Presence: Constant efforts are taken to patrol illegal activities within the AMPR. Enforcement and gradual sanctions mechanisms are applied with actors that disrespect rules. |
| Number of actors (A1) | As the number of actor groups increases, it is more likely that they have heterogeneous interests and practices, making it more difficult to create consensus and agreements. This decreases the likelihood of CA | Vedeld 2000; Ostrom 2009; SESMAD 2014 | Small: Description of reduced group size with common interests Medium: Description of moderate-size group with some common interests Large: Description of an extensive group size with different interests |
| As the number of actor groups increase, transaction costs (i.e. monitoring, communication and coordination) increase. This decreases the likelihood of CA | Ostrom 2009 | Small: Description of reduced group Medium: Description of moderate-size group Large: Description of an extensive group size | |
| Socioeconomic attributes (A2) | Economic heterogeneity increases the likelihood of CA (i.e. Wealthy actors can afford transaction costs or invest) | Poteete and Ostrom 2004 | Low: Economic wealth is very similar among actors Medium: Economic wealth is more or less similar High: Economic wealth of actors is different among actors |
| History and past experiences (A3) | High frequency of negative experiences with management affects actors’ behavior, decreasing the likelihood of CA | Torres Guevara et al. 2016; London et al. 2017 | Low: negative experiences among actors have rarely occurred and have not significantly affected actors’ behavior Medium: negative experiences among actors have often occurred and has affected actors’ behavior but not significantly High: negative experiences among actors have occurred more frequently and have significantly affected actors’ behavior |
| Location (A4) | Actors located far apart increases transaction costs (e.g. monitoring, getting together, access to markets), decreasing the likelihood of CA | Ostrom 2009 | Close: Description that location of actors is proximate to each other Far: Description that location of actors is distant from each other |
| Leadership/entrepreneurship (A5) | Strong leadership and entrepreneurial skills increase the likelihood of CA | Vedeld 2000; Pomeroy et al. 2001; Ostrom 2009; Gutiérrez et al. 2011 | Weak: Lack of leadership skills, disagreement with leader actions or actors neglecting to follow leaders Strong: Presence of leadership skills has positive effect on requesting institutional support and being followed and respected by actors |
| Trust/social capital (A6) | High to moderate levels of confidence and close relationship among local actors is likely to increase CA | Cinner et al. 2012; Basurto et al. 2013 | Low: Negative or little confidence, and/or conflictive relationship among actors Medium: Confidence and relationship among actors is intermediate High: Positive confidence or close relationship among actors |
| Dependence (A8) | High dependence on AMPR resources to obtain income and sustain livelihoods increases the likelihood of CA | Ostrom 2009; Basurto et al. 2013 | Low: Negative or little dependence on AMPR fishing resources Medium: Intermediate dependence on AMPR fishing resources High: Positive or strong dependence on AMPR fishing resources |
