Each year, over 45,000 metric tons of waste are generated in US national parks through a variety of means, including park operations, visitation, and other sources. In an effort to address these impacts, the National Park Service (NPS) has partnered with commercial and non-profit organizations to implement the Zero Landfill Initiative (ZLI). The goal of the ZLI is to realize a steady decrease in waste generated in parks, and an increase in materials being sent for recycling. Through this initiative and aligning research, efforts to mitigate waste and recycling issues with visitors is underway; however, to date there have been no attempts to understand the perspectives of those individuals who manage these parks on a daily basis. This study explored Theory of Planned Behavior-based constructs regarding disposal of waste and recycling using surveys with NPS employees and park concession staff in Yosemite, Grand Teton, and Denali National Parks. Results indicate that perceived difficulty and moral norms related to disposal of waste and recycling are significant drivers of self-reported behavior and intent with NPS and concession staff. Generally, concession staff perceptions align with the goals of ZLI more than those of NPS staff. This research adds to the limited understanding of land mana­ger perceptions, and results provide justification for future messaging and trainings that could improve sustainable management of these and other NPS units in the future.Keywords: Park Management; Visitor Use; Recycling; Waste Management; Communication; Human Behavior; Leave No Trace

An excerpt from the concluding chapter of the 4th edition of this standard textbook.

IntroductionThe effects of climate change and associated extreme weather events (EWEs) present substantial threats to well-being. EWEs hold the potential to harm sexual health through pathways including elevated exposure to HIV and other sexually transmitted infections (STIs), disrupted healthcare access, and increased sexual and gender-based violence (SGBV). The WHO defines four components of sexual health: comprehensive sexuality education; HIV and STI prevention and care; SGBV prevention and care; and psychosexual counselling. Yet, knowledge gaps remain regarding climate change and its associations with these sexual health domains. This scoping review will therefore explore the linkages between climate change and sexual health.Methods and analysisFive electronic databases (MEDLINE, EMBASE, PsycINFO, Web of Science, CINAHL) will be searched using text words and subject headings (eg, Medical Subject Headings (MeSH), Emtree) related to sexual health and climate change from the inception of each database to May 2021. Grey literature and unpublished reports will be searched using a comprehensive search strategy, including from the WHO, World Bank eLibrary, and the Centers for Disease Control and Prevention. The scoping review will consider studies that explore: (a) climate change and EWEs including droughts, heat waves, wildfires, dust storms, hurricanes, flooding rains, coastal flooding and storm surges; alongside (b) sexual health, including: comprehensive sexual health education, sexual health counselling, and HIV/STI acquisition, prevention and/or care, and/or SGBV, including intimate partner violence, sexual assault and rape. Searches will not be limited by language, publication year or geographical location. We will consider quantitative, qualitative, mixed-methods and review articles for inclusion. We will conduct thematic analysis of findings. Data will be presented in narrative and tabular forms.Ethics and disseminationThere are no formal ethics requirements as we are not collecting primary data. Results will be published in a peer-reviewed journal and shared at international conferences.
