Zoning has been proposed as a way of reducing unhealthy food access for youth, but little research has evaluated outcomes of proposed or existing junk food bans, and even less research has considered equity implications of such zoning policies. In this simulation study, set in the Region of Waterloo, Ontario (Canada), we examined how secondary student access to fast food restaurants and convenience stores would change under such a policy over 10 years in a mid-sized Canadian municipality. Outcomes are presented by school-level advantage (derived from the proportion of students in equity-deserving subgroups: low income, students who speak English as an additional language, and students not born in Canada). Current fast food restaurant and convenience store access was higher around schools with a higher proportion of equity-deserving students, and access remained higher around these schools even after 10 years under each policy scenario. After 10 years, the mean number of fast food restaurants and convenience stores within a 1-km network distance still exceeded five unhealthy outlets for both disadvantaged and advantaged schools, which was above the threshold associated with lower junk food consumption among youth. These findings bring into question the potential effectiveness and equity implications of restrictive zoning policies aimed at protecting youth from poor-quality food environments. Planners may consider prioritizing interventions to improve the healthfulness of food environments around schools where there are large proportions of equity-deserving students, but consideration of different interventions seems warranted in this context.

• Residents living in a green bin regime support green bin more than those who are not. • Convenience (time and space to sort waste) is highly predictive of green bin support. • Concern about the environment is highly predictive of green bin support. • The notion that green bin causes people to discard more food does not predict support. • Residents in a proposed green bin waste regime disagree on the most issues. Food waste remains a high priority greenhouse gas (GHG) emission problem and household curbside collection – green bin 1 1 This literature has not yet settled on common terminology. Wu et al., (2019) use the term "curbside composting carts", while (Geislar 2017) uses the term "organics collection programs" OCP. The scope of our study is bins used to collect food waste at individual households. - with mass treatment is often adopted as a viable solution for GHG reduction. The aim of this study is to explore attitudinal and situational predictors of support for residential curbside green bin programs. Using responses to 517 household surveys from the mid-sized Canadian cities of London, Ontario (proposed green bin program) and Kitchener-Waterloo (KW), Ontario (operating green bin program for 10+ years) comparison of means t-tests, correlations and linear regression are used to test five hypotheses derived from the food waste and waste diversion literatures that predict green bin support: situational factors, current food wasting, theory of planned behaviour attitudes, concern that green bin encourages food wasting, and concern that food waste ends up in the garbage regardless of green bin. There is some support for all five hypotheses. Residents in Kitchener-Waterloo were significantly more supportive (83%) than those in London (65%). While residents in both communities are supportive because of the perceived convenience and environmental benefits of the green bin, the number of regression model predictors is greater in London (16 compared to 9 for Kitchener-Waterloo). The findings overall suggest sustained municipal education at the implementation stage may lead to positive resident habituation to green bin and thus, durable public buy-in. [ABSTRACT FROM AUTHOR]
