RESUMEN

This paper examines the links between place attachment and older persons' preferences to age in place, and factors that disrupt these preferences. We use data from the 2001-2021 Household, Income and Labour Dynamics in Australia Survey and panel-data modelling to confirm strong associations between several place attachment dimensions and aging-in-place preferences. Strong ties to children, strong social capital, residence in social housing, homeownership status, housing wealth, and home and neighborhood satisfaction are all positively linked to a stronger preference to age in place. Our findings reveal important differences between older homeowners and older non-owners. For owners, closeness to children is a strong predictor of aging-in-place preferences, although mortgage debt can trigger involuntary moves. For non-owners, tenure security achieved through longer durations at one's address of residence is linked to stronger aging-in-place preferences. However, private renters are more often exposed to involuntary moves. We discuss the policy implications of these disruptions.

RESUMEN

Urbanization and land use change are leading causes of declines in pollinator abundance and diversity. However, researchers in different regions of the world have found that some pollinators can thrive in urban landscapes, depending on land use practices, environmental conditions, and species traits. Residential landscapes constitute a significant portion of urban green space and thus, residents' adoption of landscape practices to promote pollinators can play a central role in addressing the global pollinator challenge. Yet, although residents' willingness and intention appear strong, adoption of pollinator-friendly gardening remains low. The present study - guided by the Diffusion of Innovations theory - aimed to build empirical understanding by surveying 1598 [State] residents on their experiences and perceptions related to pollinator-friendly gardening to determine the most salient barriers and opportunities to engagement. Key findings suggest making the practice more widely observable and reducing perceived complexity in learning to do the practice are critical to promoting adoption. This demonstrates, in practical terms, that: (1) targeted efforts to build residents' actionable knowledge about pollinator-friendly gardening may significantly reduce uncertainty and boost the likelihood of adoption; and (2) examples of active pollinator gardens need to be more widely showcased and popularized (e.g., through experiential or virtual demonstrations). We also found most residents living in homeowner associations (HOAs) believed HOA policies on pollinator-friendly gardening were restrictive or the residents were unsure whether they are allowed to practice pollinator-friendly gardening. Given these perceptions strongly associated with residents' low intent to engage in pollinator-friendly gardening, a major opportunity exists to diffuse the practice and increase adoption by working with HOAs and community leaders to become promoters of - rather than barriers to - pollinator-friendly gardening.

RESUMEN

Using a population-based longitudinal dataset in Australia over nearly 20 years, this study examines the impact of tenure instability on mental health and psychological distress among a low-income working-age population. The analysis compares private renters (who are notable for their relative tenure insecurity in the Australian context) and homeowners with similar sociodemographic characteristics. To enhance group comparability and address the presence of time-varying covariates that confound and mediate the relationship between tenure exposure and mental health, marginal structural models were used applying weights estimated cumulatively over time. The results show that while private rental tenants report worse mental health than homeowners initially (mental health difference: Beta = -5.29, 95%CI -7.61 to -2.97; psychological distress difference: Beta = 1.77, 95%CI 0.55 to 2.99), this difference diminishes to become statistically indistinguishable by 5-6 years of occupancy (mental health difference at year 6: Beta = -2.09, 95%CI -4.31 to 0.13, predicted mental health increases: from 65.06 to 69.83 for private renters and from 70.46 to 72.02 for homeowners; psychological distress difference at year 5: Beta = 0.81, 95%CI -0.09 to 1.71, predicted psychological distress decreases: from 19.85 to 18.04 for private renters and from 17.95 to 17.10 for homeowners). Residential stability is particularly beneficial for private renters in early middle adulthood (35-44 years), with each additional year of stable occupancy for private renters correlated with a 0.99 (95%CI 0.46 to 1.53) increase in mental health and a -0.47 (95%CI -0.69 to -0.24) decrease in psychological distress. The findings provide evidence that stable and secure rental tenure is protective of mental health, and the mental health of stable renters becomes comparable to that of homeowners over time. This adds support for housing policies that promote and improve the stability and security of rental tenure.

RESUMEN

Contamination of urban surface waters by herbicides is an increasing concern; however, sources of contamination are poorly understood, hindering the development of mitigation and regulatory strategies. Impervious surfaces, such as concrete in driveways and paths are considered an important facilitator for herbicide runoff to urban surface waters following applications by residential homeowners. This study assessed the transferability of a herbicide from concrete pavers treated with an off-the-shelf product, containing simazine as the active herbicide, marketed for residential homeowner application to impervious surfaces. Commercially available pavers were treated according to label directions and the effects of exposure time prior to irrigation, repeated irrigations, and dry time between irrigations on transferability of simazine to runoff were assessed. Simazine transferability was greatest when receiving an initial irrigation 1 h after application, with concentrations in runoff reduced by half when exposure times prior to the first irrigation were >2 days. Concentrations remained stable for repeated irrigations up to 320 days and exposures to outdoor conditions of 180 days prior to a first irrigation. Dry time between irrigations significantly influenced simazine transfer to runoff. Dry periods of 140 days resulted in approximately a 4-times increase in simazine transferability to runoff. These results suggest that herbicides used by homeowners, or any other users, on impervious surfaces are available to contaminate runoff for prolonged time periods following application at concentrations that may pose risks to aquatic life and for reuse of harvested runoff on parks and gardens. Regulators should consider the potential of hard surfaces to act as reservoirs for herbicides when developing policies and labelling products.

RESUMEN

Efforts to mitigate outdoor water use in Florida's urban landscapes increasingly include promotion of regionally appropriate landscaping based on its documented effectiveness. Targeted initiatives, however, require an understanding of mechanisms underpinning low irrigation use in single-family homes with Florida-Friendly Landscaping (FFL). This paper reports survey research conducted in southwest Florida to identify factors associated with irrigation practices among FFL clients. Results indicate that approximately half of survey participants irrigated less frequently than once per week year-round. Aesthetic considerations, horticultural knowledge, and membership in a homeowner's association (HOA) with rules regarding yard care were key variables underlying landscape characteristics and maintenance, while property values, water conservation attitudes, lawn grass, and in-ground irrigation system use significantly predicted irrigation practices. Homes with in-ground irrigation systems were more than six times more likely to water their landscapes at least once per week during the warm season when residential outdoor water use is at its peak. A $100,000 increase in a home's market value increased the odds of weekly watering by a multiplicative factor of two, whereas a one-point increase in a six-item Likert scale used to measure a homeowner's water conservation attitude decreased the odds by 76%. Homes with no grass in the landscape were 71% less likely to water on a weekly basis. Providing homeowners, and HOAs, with educational resources that build on existing support for water conservation could augment adoption of low maintenance plants and sustainable practices in Florida's urban landscapes.

RESUMEN

Water resources provide many benefits that generate value for residents and recreation users alike but run-off from agricultural and impervious surfaces can impair water quality, reducing any generated value. A possible solution to this problem is the construction of treatment wetlands to remove excessive nutrients from water bodies. This study uses environmental and economic data to approximate the costs of constructing and operating free surface water wetlands to remove phosphorus and estimates the amenity and recreational benefits of the resulting improvements in water quality for 24 lakes in Ohio. A ten percent improvement in water quality from a decrease in phosphorus loadings generates positive net benefits for all lakes in the sample with a lifetime cost benefit ratio of 2.92. The study also examines the potential use of constructed wetlands as the sole strategy to achieve a reduction goal for phosphorus loadings and find that the costs of doing so are prohibitive. Constructed wetlands can be a cost-effective component of a comprehensive strategy for small-scale nutrient reduction and water quality improvements for surface water bodies, but other treatment methods would be required to achieve any proposed targeted improvements.

RESUMEN

The current system for managing natural disaster risk in the United States is problematic for both homeowners and insurers. Homeowners are often uninsured or underinsured against natural disaster losses, and typically do not invest in retrofits that can reduce losses. Insurers often do not want to insure against these losses, which are some of their biggest exposures and can cause an undesirably high chance of insolvency. There is a need to design an improved system that acknowledges the different perspectives of the stakeholders. In this article, we introduce a new modeling framework to help understand and manage the insurer's role in catastrophe risk management. The framework includes a new game-theoretic optimization model of insurer decisions that interacts with a utility-based homeowner decision model and is integrated with a regional catastrophe loss estimation model. Reinsurer and government roles are represented as bounds on the insurer-insured interactions. We demonstrate the model for a full-scale case study for hurricane risk to residential buildings in eastern North Carolina; present the results from the perspectives of all stakeholders-primary insurers, homeowners (insured and uninsured), and reinsurers; and examine the effect of key parameters on the results.
