The environmental identity (EID) scale, first published in 2003, was developed to measure individual differences in a stable sense of interdependence and connectedness with nature. Since then, it has been reliably correlated with measures of environmental behavior and concern. However, the original scale was developed based on U.S. college students, raising questions about its validity for other types of populations. This study revised the EID scale and tested it in five countries (four continents) with a total sample size of 1717 participants. Results support strong internal consistency across all locations. Importantly, EID was significantly correlated with behavior and with environmental concern. This research gives us greater confidence that the EID construct is meaningful across different cultural contexts. Because the revised EID was designed to be relevant to a wider range of people and experiences, it is recommended as a replacement for the 2003 version.

Experiences in nature benefit humans in a variety of ways, including increasing health and well-being, reducing stress, inspiring creativity, enhancing learning, and fostering environmental stewardship values. These experiences help define the relationship people have with nature which is often correlated with a person’s level of environmental concern as well as their engagement in pro-environmental behaviors. A more informed understanding of the ways in which interactions with the natural environment can foster connection to nature requires that we are able to measure our perceived relationship to the environment. Dozens of tools measure people’s connection to nature—the strength of those perceived relationships with the natural world. Although the tools have been primarily developed to answer research questions, practitioners are increasingly interested in understanding whether and in what ways their work—in areas including environmental education, urban planning, and park management, for example—influences people’s connection to nature. In 2018, we launched a participatory process involving researchers and practitioners in a review of existing connection to nature assessment tools with the intention of identifying tools that would be useful to practitioners, as well as defining needs in research. This paper chronicles the process’s outcomes, including a discussion of opportunities for future research.

Although images play a significant role in environmental communications, few studies have empirically examined whether positive or negative images are more effective at engaging attention and promoting behavior change. We conducted a 6‐week public experiment at the Florida Museum of Natural History in Gainesville, Florida, to test whether viewing a photography exhibit featuring images of the impacts of marine plastic pollution on ocean ecosystems (negative valence) or images of pristine ocean ecosystems (positive valence) would increase engagement, monetary donations to conservation, and pledges to help protect the ocean from plastic pollution. We tracked 1179 adults while observing the negative exhibit and 1304 adults while observing the positive exhibit. Of the adults tracked, significantly more engaged with the negative exhibit (270; 22.90%) than the positive exhibit (159; 12.19%). The mean number of pledges per visitor for the negative exhibit was significantly higher than for the positive exhibit. However, there was not a significant difference in donations between the two exhibits. These results suggest that environmental organizations that seek to capture attention should consider using images that show the negative impacts of human behavior on the environment.

Environmental education has the potential to help reduce negative human–wildlife interactions by increasing positive attitudes toward wildlife and providing participants with knowledge and skills that can help mitigate conflict situations and promote safety. To promote positive human–wildlife relationships, effective programs could be implemented widely in areas near remote wildlife reserves and protected areas. We created and evaluated a new environmental education program for 10‐ to 13‐year‐old students in rural schools in India where human–wildlife conflicts with large mammals frequently occur. Between July 2019 and March 2020, we tested the program at 129 schools, reaching 4331 students. The program, which was iteratively designed to fit the local context, is both cost‐effective and scalable. We found that participation in the program resulted in a significant positive increase in local environmental knowledge, in knowledge of safe behaviors, and in some measures of environmental attitudes. This paper reports on the lessons learned while creating this program that may help other organizations interested in using environmental education in regions where negative human–wildlife interactions frequently occur.

Although they are only home to 16% of the global human population, high-income countries produce approximately one third of the world’s waste, the majority of which goes to landfills. To reduce pressure on landfills and natural systems, environmental messaging should focus on reducing consumption. Messages that signal social norms have the potential to influence people to reduce their consumption of comfort goods, such as straws, which are not a necessity for most people. We conducted a randomized field-experiment at a marine park in Portugal to test whether different normative messages reduced visitors’ paper straw use when compared to non-normative messages. We found that a message framed around a positive injunctive norm significantly reduced straw use compared to a non-normative message. We estimated that using the message at 17 park concession stands could keep over 27500 straws out of landfills annually and save the park money after two years.

Many environmental organizations use photographic images to engage donors and supporters. While images play a role in fundraising, visual framing remains understudied in the environmental field. Few real-world experiments have examined which types of images result in higher donations to biodiversity conservation. We examined the role of images in conservation fundraising through a public experiment at Zoomarine, a marine park located in southern Portugal. Zoomarine runs a program called Dolphin Emotions where visitors pay to learn about dolphin biology and to interact with dolphins. We placed a donation box and a large informational poster about the Marine Megafauna Foundation, a conservation partner, in the lounge of the Dolphin Emotions program, which is open to participants and their families. The text on the poster, which solicited donations for the Marine Megafauna Foundation, was held constant, while four different image conditions were tested: dolphins, ocean wildlife, children, and people staring out from the poster (i.e., “watching eyes”). Each image condition was displayed for three days at a time and was on display for at least seven randomly assigned three-day periods over the course of 91 days. 20,944 visitors passed the donation box and the four poster conditions during this time and a total of € 952.40 was collected. The differences in mean donations in € per visitor per 3-day period were not statistically significant, F(3, 25) = 0.745, p = 0.54. Thus, we did not find that different images had a significant influence on donations to conservation. This may be due to our choice of visual frames or to the use of a donation box, which is a passive fundraising channel. Future research should examine how visual framing influences donations in other public settings and should test the influence of other visual frames on philanthropic behavior.
