Formative experiences and psychological distance in the lives of contemporary environmentalists.

Introduction: We use the term "environmentalists" to describe the people who are highly and actively engaged and involved in environmental issues like climate change. Environmentalists consistently advocate, research, or volunteer to do the work needed to address environmental challenges. Factors that drive contemporary environmentalists remain understudied. Methods: We, therefore, ask: what formative experiences drive environmentalists on climate change and other environmental problems at present? We frame this exploration through the significant life experiences (SLE) literature, which examines people and environmental pathways. We also ask: how do feelings of perceptual/actual distance or closeness to environmental threats and climate change shape a person's decision to become an environmentalist? We anchor this query to the psychological distance (PD) literature that explores how people perceive external phenomena and the role distance plays in their conception. To answer both questions, we use qualitative methods and draw on 33 interviews with environmentalists involved in environmental protection work for an average of 91 h in the past 4 weeks. Results: We find that environmentalists spoke about several formative experiences broadly consistent with what has been documented in the SLE literature. Traumatic experiences were especially influential for our sample of environmentalists. Our findings also reveal that PD, especially social, plays a role in the lives of environmentalists. Discussion: Study findings could help scholars and practitioners deepen their understanding of contemporary environmentalists. Practitioners, in particular, could use this knowledge to help environmentalists by providing them with tailored resources and support.

Displacement and degradation: Impediments to agricultural livelihoods among ethnic minority farmers in post-war Sri Lanka.

Our understandings of the effects of war on land and resource access following armed conflicts are often shaped (and limited) by a reliance upon remotely sensed data. Here, we analyze household-level survey and community-level focus group data collected in Sri Lanka following the end of the nation's ethno-religiously rooted civil war (1983-2009) to determine if and how the war differently affected the nation's rice farmers. Our synthetic analyses revealed geographic variation in agricultural livelihood viability in post-war Sri Lanka, demonstrating how the protracted effects of war are exacerbating the vulnerability of rural Sri Lanka's ethno-religious minority (Tamil and Moor) populations by (re-)shaping access to critical natural resources, including both land and irrigation water.

How do migration decisions and drivers differ against extreme environmental events?

Migration is often understood to be a livelihood strategy to cope with the effects of environmental threats and climate change. Yet, the extent to which migration decisions differ due to the type, severity, and frequency of environmental events has been little explored. This paper employs household surveys in southwestern Bangladesh to explore this research gap. A multinominal regression model is used to simulate reported future migration decisions (200 sample households) in the context of both rapid-onset (i.e. cyclone and flood) and slow-onset (salinity, siltation, and riverbank erosion) environmental phenomena. Results show: i) previous disaster experience and increasing conflict in the community motivate migration in the near future in the context of slow-onset phenomena (salinity); (ii) economic strength and self-efficacy increase non-migration intention in both contexts of sudden and slow-onset events; and (iii) the extent and pattern of these influences on migration differ across demographics, including education, religion, and age. Importantly, this analysis shows that the relationship between migration decisions and the type, severity, and frequency of environmental events is influenced by socioeconomic conditions. Therefore, this research supports future adaptation planning specifically tailored to the type and exposure of extreme environmental events.

Childhood trauma and other formative life experiences predict environmental engagement.

Environmental problems continue to intensify. Yet, despite scientific consensus on threats such as climate change, broadscale public engagement with the issue is elusive. In this paper, we focus on childhood formative experiences and the extent to which they are correlated with environmental engagement. We consider two forms of environmental engagement: civic engagement, measured in hours per month devoted to an environmental protection cause, and private-sphere green behavior. Past studies about significant life experiences have shown that formative experiences, especially in childhood, correlate with environmentally sensitive attitudes and vocations in later life. However, we know less about the formative life events experienced by contemporary environmentally engaged persons. Looking at a nationally representative sample of American adults (n = 449), we find that childhood trauma predicts both civic engagement and green behavior. We also find that childhood experiences in nature and childhood travel experiences predict green behavior but not civic engagement.

Prepare developed democracies for long-run economic slowdowns.

Developed democracies proliferated over the past two centuries during an unprecedented era of economic growth, which may be ending. Macroeconomic forecasts predict slowing growth throughout the twenty-first century for structural reasons such as ageing populations, shifts from goods to services, slowing innovation, and debt. Long-run effects of COVID-19 and climate change could further slow growth. Some sustainability scientists assert that slower growth, stagnation or de-growth is an environmental imperative, especially in developed countries. Whether slow growth is inevitable or planned, we argue that developed democracies should prepare for additional fiscal and social stress, some of which is already apparent. We call for a 'guided civic revival', including government and civic efforts aimed at reducing inequality, socially integrating diverse populations and building shared identities, increasing economic opportunity for youth, improving return on investment in taxation and public spending, strengthening formal democratic institutions and investing to improve non-economic drivers of subjective well-being.

Identity and Guilt as Mediators of Pro-environmental Spillover.

Policymakers are interested in programs that increase targeted pro-environmental behavior (PEB) and spill over to increase non-targeted PEBs. Theoretically, guilt should lead to negative spillover and identity to positive spillover, though this has rarely been tested empirically. Additionally, little is known about how reminders of past PEB behavior might also lead to downstream spillover effects. Across two studies, participants (Study 1: 377 MTurk workers; Study 2: 172 undergraduates) were randomly assigned to write about a prior PEB, an anti-environmental behavior, or to a control condition. Subsequently, respondents were given an opportunity to perform a PEB2 and completed measures of PEB3 intentions. Results showed some evidence of positive (through increasing identity) and negative (through decreasing guilt) indirect spillover pathways from prior PEB reminders to PEB2 performance and PEB3 curtailment intentions (but not efficiency upgrade intentions). However, there were no overall spillover effects from PEB reminders to PEB2 performance or PEB3 intentions, as the positive and negative indirect effects canceled each other out. Results also showed positive spillover from PEB2 performance to PEB3 curtailment intentions through increasing environmental guilt. The strength of the spillover effects depended on the comparison group for the experimental manipulation, whether environmental guilt or global guilt was measured, and the type of PEB. The results suggest that environmental communications that remind people of their prior PEB may not meaningfully spill over to further PEB performance or intentions.

A Study of Perceived Nature, Shade and Trees and Self-Reported Physical Activity in Denver.

(1) Background: Current evidence on the association between greenery and physical activity (PA) remains inconsistent. Most studies on this association use objective measures of greenness, which do not reveal people's perceptions of greenness in neighborhoods, or the role of quality components of greenness, such as shade, trees, and the presence of nature on this association. (2) Methods: Drawing on data from the Neighborhood Environment and Health Survey-a cross-sectional population-based survey of Denver residents in 2007-we examined which measures of greenness (perceived and objective) correlated with the self-reported PA. We also assessed how components of perceived greenness, shade, trees and the presence of nature, correlated with PA. (3) Results: Perceived greenness, reflecting perception of trees, shade and the presence of nature, was positively associated with reported moderate-vigorous PA. Conclusion: Findings provide evidence that quality aspects of greenness affect people's perception of the neighborhood in a way that relates to PA. The individual contributions of shade, trees, and the presence of nature in this association should be analyzed in future studies. Understanding the link between shade and trees and PA has implications for how to plan for walkability and sun safety at the neighborhood scale.

Psychologists and the problem of population growth: Reply to Bridgeman (2017).

Bridgeman (2017) describes the important role of population growth in contributing to environmental problems. The present essay argues that population is an important component of human impact on the environment, but it must be considered in combination with consumption rates. A place-based approach, examining the local context for reproductive decisions, is necessary to assess population growth as a contributor to environmental impact and to develop appropriate behavioral interventions.

Examining adaptations to water stress among farming households in Sri Lanka's dry zone.

Climate change is increasing water scarcity in Sri Lanka. Whether these changes will undermine national-level food security depends upon the ability of the small-scale farmers that dominate rice production and the institutions that support them to overcome the challenges presented by changing water availability. Analyzing household survey data, this research identifies household, institutional, and agroecological factors that influence how water-stressed farmers are working to adapt to changing conditions and how the strategies they employ impact rice yields. Paralleling studies conducted elsewhere, we identified institutional factors as particularly relevant in farmer adaptation decisions. Notably, our research identified farmers' use of hybrid seed varietals as the only local climate adaptation strategy to positively correlate with farmers' rice yields. These findings provide insight into additional factors pertinent to successful agricultural adaptation and offer encouraging evidence for policies that promote plant breeding and distribution in Sri Lanka as a means to buffer the food system to climate change-exacerbated drought.

Drinking water insecurity: water quality and access in coastal south-western Bangladesh.

National drinking water assessments for Bangladesh do not reflect local variability, or temporal differences. This paper reports on the findings of an interdisciplinary investigation of drinking water insecurity in a rural coastal south-western Bangladesh. Drinking water quality is assessed by comparison of locally measured concentrations to national levels and water quality criteria; resident's access to potable water and their perceptions are based on local social surveys. Residents in the study area use groundwater far less than the national average; salinity and local rainwater scarcity necessitates the use of multiple water sources throughout the year. Groundwater concentrations of arsenic and specific conductivity (SpC) were greater than surface water (pond) concentrations; there was no statistically significant seasonal difference in mean concentrations in groundwater, but there was for ponds, with arsenic higher in the dry season. Average arsenic concentrations in local water drinking were 2-4 times times the national average. All of the local groundwater samples exceeded the Bangladesh guidance for SpC, although the majority of residents surveyed did not perceive their water as having a 'bad' or 'salty' taste.

Expanding the role for psychology in addressing environmental challenges.

Environmental challenges, though daunting, present an important area for psychologists to apply their knowledge. Psychological theories, research methods, and interventions are essential for examining the questions about human impacts, tendencies, and capacities that are integral to constructing effective responses to these challenges. Although a great deal of relevant research has been done, there is scope for psychologists to be more extensively involved. Following a brief review of existing research, we outline some important new directions. We also highlight 2 key divergences, arguing that psychological research needs to expand beyond a traditional, theory-based and decontextualized approach to environmental issues to incorporate a contextualized or "place-based" approach and a willingness to collaborate in interdisciplinary research teams that focus on specific environmental problems. Suggestions for promoting such interdisciplinary collaborations are reviewed. We encourage psychologists to expand their engagement with important environmental issues through multiple research approaches in order to further their understanding of human behavior, contributions to human well-being, and relevance to other disciplines and to society.

The effects of household management practices on the global warming potential of urban lawns.

Nitrous oxide (N2O) emissions are an important component of the greenhouse gas (GHG) budget for urban turfgrasses. A biogeochemical model DNDC successfully captured the magnitudes and patterns of N2O emissions observed at an urban turfgrass system at the Richland Creek Watershed in Nashville, TN. The model was then used to study the long-term (i.e. 75 years) impacts of lawn management practice (LMP) on soil organic carbon sequestration rate (dSOC), soil N2O emissions, and net Global Warming Potentials (net GWPs). The model simulated N2O emissions and net GWP from the three management intensity levels over 75 years ranged from 0.75 to 3.57 kg N ha(-1)yr(-1) and 697 to 2443 kg CO2-eq ha(-1)yr(-1), respectively, which suggested that turfgrasses act as a net carbon emitter. Reduction of fertilization is most effective to mitigate the global warming potentials of turfgrasses. Compared to the baseline scenario, halving fertilization rate and clipping recycle as an alternative to synthetic fertilizer can reduce net GWPs by 17% and 12%, respectively. In addition, reducing irrigation and mowing are also effective in lowering net GWPs. The minimum-maintenance LMP without irrigation and fertilization can reduce annual N2O emissions and net GWPs by approximately 53% and 70%, respectively, with the price of gradual depletion of soil organic carbon, when compared to the intensive-maintenance LMP. A lawn age-dependent best management practice is recommended: a high dose fertilizer input at the initial stage of lawn establishment to enhance SOC sequestration, followed by decreasing fertilization rate when the lawn ages to minimize N2O emissions. A minimum-maintained LMP with clipping recycling, and minimum irrigation and mowing, is recommended to mitigate global warming effects from urban turfgrass systems. Among all practices, clipping recycle may be a relatively malleable behavior and, therefore, a good target for interventions seeking to reduce the environmental impacts of lawn management through public education. Our results suggest that a long-term or a chronosequence study of turfgrasses with varying ages is warranted to capture the complete dynamics of contribution of turfgrasses to global warming.

The Environmental Cost of Misinformation: Why the Recommendation to Use Elevated Temperatures for Handwashing is Problematic.

Multiple government and health organizations recommend the use of warm or hot water in publications designed to educate the public on best practices for washing one's hands. This is despite research suggesting that the use of an elevated water temperature does not improve handwashing efficacy, but can cause hand irritation. There is reason to believe that the perception that warm or hot water is more effective at cleaning one's hands is pervasive, and may be one factor that is driving up unnecessary energy consumption and greenhouse gas emissions. We examine handwashing practices and beliefs about water temperature using a survey of 510 adults in the United States. The survey included measures of handwashing frequency, duration, the proportion of time an elevated temperature was used, and beliefs about water temperature and handwashing efficacy. We also estimate the energy consumed and resultant carbon dioxide equivalent emissions (CO2eq) in the U.S. due to the use of elevated temperatures during handwashing. Participants used an elevated temperature 64% of the time, causing 6.3 million metric tons (MMt) of CO2eq which is 0.1% of total annual emissions and 0.3% of commercial and residential sector emissions. Roughly 69% of the sample believed that elevated temperatures improve handwashing efficacy. Updating these beliefs could prevent 1 MMt of CO2eq annually, exceeding the total emissions from many industrial sources in the U.S. including the Lead and Zinc industries. In addition to causing skin irritation, the recommendation to use an elevated temperature during handwashing contributes to another major threat to public health-climate change. Health and consumer protection organizations should consider advocating for the use of a "comfortable" temperature rather than warm or hot water.

Effect of BMI on prediction of accelerometry-based energy expenditure in youth.

PURPOSE: The objective of this study is to determine the effect of body mass index (BMI) on level of agreement between six previously established prediction equations for three commonly used accelerometers to predict summary measures of energy expenditure (EE) in youth. METHODS: One hundred and thirty-one youth between the ages of 10-17 yr and BMI from 15 to 44 kg·m were outfitted with hip-worn ActiGraph GT1M (Pensacola, FL), Actical (MiniMiter/Respironics, Bend, OR), and RT3 (StayHealthy, Monrovia, CA) accelerometers and spent approximately 24 h in a whole-room indirect calorimeter while performing structured and self-selected activities. Five commonly used regression and one propriety equations for each device were used to predict the minute-to-minute EE (normalized to METs), daily physical activity level (PAL), and time spent in sedentary, light, moderate, and vigorous physical activity intensity categories. The calculated values were compared with criterion measurements obtained from the room calorimeter. RESULTS: All predictive equations, except RT3, significantly over- or underpredicted daily PAL (P < 0.001), with large discrepancies observed in the estimate of sedentary and light activity. Discrepancies between actual and estimated PAL ranged from 0.05 to 0.68. In addition, BMI represented a modifier for two ActiGraph predictive equations (AG1 and AG2), affecting the accuracy of physical activity-related EE predictions. CONCLUSION: ActiGraph (AG3) and the RT3 closely predicted overall PAL (within 4.2% and 6.8%, respectively) as a group. When adjusting for age, sex, and ethnicity, Actical (AC1 and AC2) and ActiGraph (AG3) were not influenced by BMI. However, a gap between some hip-worn accelerometer predictive and regression equations was demonstrated compared with both criterion measurement and each other, which poses a potential difficulty for interstudy (e.g., different accelerometers) and intrastudy (e.g., BMI and adiposity) comparisons.

The ethical health lawyer: an empirical assessment of moral decision making.

Writing in 1999, legal ethics scholar Brad Wendel noted that "[v]ery little empirical work has been done on the moral decision making of lawyers." Indeed, since the mid-1990s, few empirical studies have attempted to explore how attorneys deliberate about ethical dilemmas they encounter in their practice. Moreover, while past research has explored some of the ethical issues confronting lawyers practicing in certain specific areas of practice, no published data exists probing the moral mind of health care lawyers. As signaled by the creation of a regular column "devoted to ethical issues arising in the practice of health law" in the Journal of Law, Medicine & Ethics, the time to address the empirical gap in the professional ethics literature is now. Accordingly, this article presents data collected from 120 health care lawyers. Presenting this population with a number of hypothetical scenarios relating to how they would respond when confronting an ethical dilemma without an obvious solution or when facing a situation in which their personal values were in tension with their professional obligations, this article represents a first step toward better understanding how lawyers who practice in health care settings understand and resolve the moral discomfort they encounter in their professional lives.
