A systematized spatial review of global protected area soundscape research

Abstract

Protected areas (PA) represent the primary mechanism to protect global ecosystems; yet current capacities often lead to geographic imbalances for PA management around the world. PA soundscapes have proved a valuable element to inform effective management, as natural sounds are important for healthy natural systems and rewarding visitor experiences. This article employed a systematized literature review of PA soundscape research, matching the areas of study described for the 218 articles, with PA from the World Database on Protected Areas (WDPA). The studies took place in 372 PA, which were cataloged by geographic location and size where possible, country, and continent. Data charting included extracted keywords, research objectives, methods, outcomes and future research needs. Numeric and geographic analysis focused on understanding the nature, extent, and distribution of the studies, while thematic analysis was applied to identify trends with respect to methods, outcomes, and future research. Study results identified content and geographic imbalances between studies in tropical and temperate zones, terrestrial and marine environments, and the Global South and North. Discussion considers how global initiatives may support information and resource sharing that facilitates knowledge and capacity transfer between the two regions.
