| Summary: | Collaborative community-based approaches are proposed as a way to overcome the difficulties exerted by a broad range of social-ecological traps that emerge at the reconfiguration of social-ecological systems onto sustainable paths. Despite this, a deep examination of the social-ecological processes and interactions that constrain these approaches in different urban contexts is still necessary to improve their success. Latin American countries have institutional, political, and social characteristics that could constrain the pathways to sustainability in different ways from countries of the Global North, particularly in their metropolitan areas. Here, we present an experience (2015–2018) held in cooperation with workers of a social cooperative framed in an urban social movement from Argentina, related to the ecological rehabilitation of a highly degraded urban stream through the management of the riparian vegetation and the reintroduction of native macrophytes. The methodology involved a codesign approach based on a set of participatory action-research tools, together with resilience system analysis through causal loop diagrams, and three different interventions of a 200-m reach at the upstream area of the San Francisco stream (Buenos Aires, Argentina). The participatory diagnostic showed a strong negative effect of the current management guidelines on the riparian and aquatic vegetation, reflecting a positive feedback loop that reinforces this negative state, and revealed a hierarchical governance regime associated with the management of the watershed. Furthermore, it detected a strong motivation of local workers to generate transformative actions in terms of the sanitary and social-ecological improvements of the local habitat. The management actions showed a relatively high short-term survival of the macrophyte transplants (30–60% in a period of 2–4 months), displaying a strong spatial structure of the survival units, and downscaling to about 10% in the long term (6–12 months after interventions). A combination of biophysical and social processes related both to institutional and rigidity traps affected the survival of the transplants, reflecting the inertia of the current management programs to ecological improvements of the stream. In summary, the present work highlights the social-ecological constraints arising from transformative collective actions toward the ecological management of a stream at a highly vulnerable and bureaucratic urban context, with implications for social-ecological urban transformations in Latin America and the design of effective participatory governance actions in alliance with local social movements. |
