Abstract: Different social-ecological systems around the world are managed under community-based natural resource management (CBNRM) strategies. This paper analyses how CBNRM strategies influence the resilience of socialecological systems to the disturbances they face, drawing upon the experience of three Latin American cases (two in Mexico and one in Colombia). The cases differ in their CBNRM approach and in the time these governance systems have been in place. By using a mixed-method approach, we review the socio-ecological history and describe each CBNRM characteristics. We then assess their resilience to socioeconomic and environmental disturbances through a set of indicators. We found that CBNRM strategies influence positively and negatively resilience and that internal decisions might address important threats. On the positive side, the social-ecological systems with longer tradition of CBNRM and more local buy-in of commonly agreed objectives appear to be more resilient to environmental challenges. But, internal governance factors such as power imbalances, poor income distribution, and gender inequities linked to CBNRM undermine resilience and foster out migration. Finally, communities appear to have limited capacities to cope with external disturbances such as global drivers of change or national policies that negatively affect their social-ecological resilience.

Abstract: Several examples of community-based natural resource management in Latin American social-ecological systems exist
in which communities control the management of common-pool resources. Understanding community perceptions of the performance
of these systems is essential to involve communities in sustainable management strategies. In this analysis of three areas in Colombia,
Mexico, and Argentina, we analyzed the local perceptions of the social and environmental challenges faced by these social-ecological
systems and how these challenges and drivers affect their resilience. To do this, we combined prospective structural analysis to unravel
stakeholders’ perceptions of each system’s functioning along with network analysis to assess resilience. We identified external variables
as the most influential variables in the Colombian and Argentine cases. In the Mexican case, larger influence is exerted by internal
variables, particularly those linked to the governance system. The case study analysis revealed that the community-based natural resource
management approach needs external support and recognition to work effectively. In the Argentine and Colombian cases, megaprojects
were perceived as controllers with medium or strong influence but low dependence. The use of ancestral knowledge (Colombia), the
history of land use (Mexico), and the history of the artisanal fishery (Argentina) were all perceived as common challenges to communitybased
natural resource management. In terms of social-ecological resilience, framed within the three-dimensional model of the adaptive
cycle, all three social-ecological systems were considered to be highly connected and resilient but with different degrees of capacity or
cumulative potential.
