Social and ecological outcomes of conservation interventions in tropical coastal marine ecosystems: a systematic map protocol



Tropical coastal marine ecosystems (TCMEs) are rich in biodiversity and provide many ecosystem services, including carbon storage, shoreline protection, and food. Coastal areas are home to increasing numbers of people and population growth is expected to continue, putting TCMEs under pressure from development as well as broader environmental changes associated with climate change, e.g. sea level rise and ocean acidification. Attention to TCMEs by conservation organizations has increased and although a variety of interventions to promote conservation and sustainable development of TCMEs have been implemented, evidence regarding the outcomes of these—for people or ecosystems—is scattered and unclear. This study takes a systematic mapping approach to identify articles that examine the ecological and social outcomes associated with conservation interventions in TCMEs; specifically in coral reef, mangrove, and seagrass habitats.


We developed a comprehensive framework of conservation interventions and outcomes, drawing on existing frameworks and related evidence synthesis projects, as well as interviews with marine conservation practitioners. We modified existing frameworks to: (i) include features of TCME that are not fully captured in existing frameworks; and (ii) further specify and/or regroup existing interventions or outcomes. We developed a search string informed by habitat, geography, interventions, and outcomes of interest, to search the peer-reviewed primary literature in four bibliographic databases and the grey literature on relevant institutional websites. All searches will be conducted in English. We will screen returned articles at the title and abstract level. Included articles will be screened at full text level and data coding will follow. Number of articles and reasons for excluding at full text level screening will be recorded. At each phase (title and abstract screening, full text screening, data coding), articles will be assessed independently by two members of the review team. Coded data will be reported in a narrative review and a database accessible through an open access, searchable data portal. We will summarize trends in the evidence base, identify interventions and outcomes where evidence can be further assessed in subsequent systematic reviews and where gaps in the literature exist, and discuss the implications of research gaps and gluts for TCME conservation policy, practice, and future research.
