Cecchi Philippe auteur aut IRD text journalArticle eng text/pdf reformatted digital access Outdoor recreational activities for leisure and for sport training have grown in popularity. Their environmental impacts remain little studied, especially the waste generated by over-frequentation. Our objective was to document how frequentation of a short mountain hiking trail can lead to significant quantities of waste. To this aim, all small objects found along a three-kilometer trail were collected and their origin determined. Polymers were predominant, and were mostly shoe sole fragments. This has never been documented and must be publicized due to the potential harmfulness to terrestrial and riparian ecosystems, and to increase the walkers' awareness. specialized Hiking Waste Plastics Environmental impact Awareness FRANCE HERAULT PIC SAINT LOUP 038 021 095 355 135-144 2023 1631-0713 https://www.documentation.ird.fr/hor/fdi:010087473 10.5802/crgeos.199 1631-0713 [F B010087473] https://www.documentation.ird.fr/hor/fdi:010087473 https://horizon.documentation.ird.fr/exl-doc/pleins_textes/2023-04/010087473.pdf IRD - Base Horizon / Pleins textes 2023-04-14 2026-06-12 fdi:010087473 fre
