A systematic review of social participation in ecosystem services studies in Latin America from a transdisciplinary perspective, 1996-2020.

In this article, we propose that ecosystem services (ES) should be studied integrating social participation and the narrative of social actors. We analyzed the ES literature (1996-2020) in Latin America (LA), basing our review on the concept that the study of this topic should be transdisciplinary and post-normal (i.e., extended peer communities). We prepared the review using the Scopus® and Web of Science™ (WoS) databases. We found 1069 articles related to social participation in ES studies in 20 LA countries, identifying 310 articles for further analysis using screening and eligibility protocols. We also used a random sample (n = 50) of the 310 articles for a detailed analysis of social participation and extended peer communities. Results showed that articles increased from seven in 2010 to 39 per year from 2015 to 2019. English is the primary language used (91% of the articles), with only one journal accepting publications in Spanish. The most common collaboration combination has been one LA author and one or more non-LA authors (41% of the articles). The semantic network analysis showed 35 thematic clusters, with the most common corresponding to ES protection and provision issues. Direct social participation was included in 62% of the articles, mainly through interviews; however, consultancy processes have dominated the participatory perspective of the authors without transformative involvement. We discuss article language and low inter-countries collaboration, both influencing the lack of social participation required for the transdisciplinary analysis of ES.

Toward social-ecological coastal zone governance of Chiloé Island (Chile) based on the DPSIR framework.

Coastal zones are complex systems where sustainability needs local participative governance, whose absence may result in conflicts between social actors. In its absence, the first step should be a diagnosis of the current situation based on integrative conceptual frameworks such as the DPSIR. However, in conflicting situations, the generated model needs validation from social actors. Chiloé Island is a critical Chilean coastal fishery and aquaculture area, coexisting with subsistence and cultural uses of marine resources. This article analyzes the current ecological state of the Chiloé coastal zone and its main social-ecological impact using a DPSIR model. We validated its results through a household survey and interviews with local experts and social actors. Results show that increased coastal fisheries and aquaculture generate a critical decrease of coastal species, eutrophication, and pollution that, along with harmful algal blooms, generate conflicts. Social validation showed that experts and local social actors have different perceptions of conflicting parties and conflict solutions. Following a post-normal approach, we propose three ideas to start social-ecological governance of Chiloé coastal marine ecosystems.

Conceptual PHES-system models of the Aysén watershed and fjord (Southern Chile): testing a brainstorming strategy.

The use of brainstorming techniques for the generation of conceptual models, as the basis for the integrated management of physical-ecological-social systems (PHES-systems) is tested and discussed. The methodology is applied in the analysis of the Aysén fjord and watershed (Southern Chilean Coast). Results show that the proposed methods can be adequately used in management scenarios characterized by highly hierarchical, experts/non-experts membership.
