It is well established that ecosystems bring meaning and well-being to individuals, often articulated through attachment to place. Degradation and threats to places and ecosystems have been shown to lead to loss of well-being. Here, we suggest that the interactions between ecosystem loss and declining well-being may involve both emotional responses associated with grief, and with observable impacts on mental health. We test these ideas on so-called ecological grief by examining individual emotional response to well-documented and publicized ecological degradation: coral bleaching and mortality in the Great Barrier Reef ecosystem. The study focuses both on one off events of coral loss and the prospect of continuing decline on the self-reported well-being of residents living within the ecosystem, visitors, and those whose livelihood is dependent on the marine resource: data from face-to-face surveys of 1870 local residents, 1804 tourists, and telephone surveys of 91 fishers and 94 tourism operators. We hypothesise that the extent to which individuals experience ecological grief is dependent on the meanings or intrinsic values (such as aesthetic, scientific, or biodiversity-based values), and is moderated by their place attachment, place identity, lifestyle dependence, place-based pride, and derived well-being. Results show that around half of residents, tourists and tourist operators surveyed, and almost one quarter of fishers, report significant Reef Grief. Reef Grief is closely and positively associated with place meanings within resident and tourist populations. By contrast respondents who rated high aesthetic value of the coral ecosystem report lower levels of Reef Grief. These findings have significant implications for how individuals and populations experience ecosystem decline and loss within places that are meaningful to them. Given inevitable cumulative future impacts on ecosystems from committed climate change impacts, understanding and managing ecological grief will become increasingly important. This study seeks to lay conceptual and theoretical foundations to identify how ecological grief is manifest and related to meaningful places and the social distribution of such grief across society.

The concept of community is often used in environmental policy to foster environmental stewardship and public participation, crucial prerequisites of effective management. However, prevailing conceptualizations of community based on residential location or resource use are limited with respect to their utility as surrogates for communities of shared environment-related interests, and because of the localist perspective they entail. Thus, addressing contemporary sustainability challenges, which tend to involve transnational social and environmental interactions, urgently requires additional approaches to conceptualizing community that are compatible with current globalization. We propose a framing for redefining community based on place attachment (i.e., the bonds people form with places) in the context of Australia's Great Barrier Reef, a World Heritage Area threatened by drivers requiring management and political action at scales beyond the local. Using data on place attachment from 5,403 respondents residing locally, nationally, and internationally, we identified four communities that each shared a type of attachment to the reef and that spanned conventional location and use communities. We suggest that as human-environment interactions change with increasing mobility (both corporeal and that mediated by communication and information technology), new types of people-place relations that transcend geographic and social boundaries and do not require ongoing direct experience to form are emerging. We propose that adopting a place attachment framing to community provides a means to capture the neglected nonmaterial bonds people form with the environment, and could be leveraged to foster transnational environmental stewardship, critical to advancing global sustainability in our increasingly connected world.
