Exposure to greenery during children’s home–school walks: Socio-economic inequalities in alternative routes
研究了波兰罗兹市不同社会经济地位儿童在上学最短、最简单和最绿的三类路线中接触绿化的差异，发现低社会经济地位儿童在所有路线上的绿化接触均低于高社会经济地位儿童，甚至其最绿路线也不及后者的最简单路线，揭示了环境不公。
Children’s home–school walks are a perfect opportunity for green routes and active transportation. However, the availability of greenery along them likely varies among different socio-economic status (SES) groups. If low-SES children have less exposure to greenery than others during these walks, this might represent environmental injustice in transportation. We assess socio-environmental inequalities regarding children’s exposure to greenery in three alternative home–school routes: the shortest, simplest, and greenest. We used a mixed-method approach, linking viewshed analysis, space syntax and network analysis using multiple Lodz (Poland) datasets. Exposure to greenery along all three types of home–school routes is consistently lower for low-SES than high-SES children, signalling environmental injustice. In particular, even the greenest home–school routes of low-SES children are less green than the simplest and shortest ones of high-SES children. Combining the knowledge of pedestrian movement and environmental justice is needed to understand and address these injustices adequately.
