Abstract
Purpose
Despite the well-known positive effects of fruits and vegetables, their consumption in many countries is lower than those recommended. This study aims to systematically examine the effects of community-based interventions on fruits and vegetables consumption in adults.
Design/methodology/approach
To collect relevant publications, the authors searched electronic databases including PubMed/MEDLINE, Scopus and Web of Science from January 2000 to July 2021. Considering random models, this study analyzed the data using weighted mean differences (WMD) and 95% confidence intervals (CI).
Findings
Among 1,621 retrieved publications, 21 articles met the inclusion criteria. The overall effect size demonstrated that, at the end of the trials, the educational interventions increased the consumption of aggregated fruits and vegetables (WMD: 0.55 serving/day, 95%CI: 0.34, 0.77), and vegetables (WMD: 0.15, 95%CI: 0.09, 0.21, I2: 33.2%; p = 0.103) in the intervention groups, compared to the control groups.
Practical implications
The subgroup analyses that were based on the type of interventions (face-to-face education compared to online interventions), location (home-based compared to the other types of interventions) and duration (24 weeks and higher) of interventions, and accompanied financial support reduced between-group heterogeneity. An efficient interventional program on increasing fruits and vegetables consumption should be part of a multi-component project.
Originality/value
To the best of the authors’ knowledge, no systematic review and meta-analysis has provided a summary of the effects of community-based interventions on fruits and vegetables consumption in adult populations, and there is no fixed conclusion that could be drawn in this regard.

Abstract
This chapter focuses on the political dimension of placemaking. While placemaking has the potential to foment political change, recent discussion about placemaking seems to revolve around its methods and outcomes. Departing from the perspective of placemaking as outcome, this chapter positions placemaking as a dynamic process, shifting attention to the actors involved and their motivations. This political dimension is explored by adopting a framework of the right to the city, enabling a critical examination of existing power structures and circumstances in the transformation of the urban landscape. Drawing on a few cases of placemaking to illustrate the questions about who has the right to make places, this chapter emphasizes the need for structural change in the transformation of urban spaces for public use. As the current approach for placemaking is criticized for fueling social inequalities, asymmetrical political processes, and spatial issues, such as gentrification and displacement, a new framework is required to reorientate placemaking toward a people-led approach. This chapter shows how, by employing the right to the city framework, placemaking can be interpreted beyond its physical outcomes as a unique set of conditions and circumstances that facilitate or hinder people's ability to make a place. Moreover, the right to the city provides a lens to examine the processes involved in the transformation of the urban landscape and acknowledges the potential of placemaking to challenge these processes.
