Theres nothing really fun about the park in winter In this book, Christina Ergler explores why play resonates differently across urban localities and seasons. She draws on Bourdieus theory of practice and Gibsons affordance theory to show that determinants of seasonal outdoor play transcend modifiable barriers such as traffic and unsuitable play spaces as well as the inevitable issue of inclement weather. In contrast, seasonal play determinants are grounded in locally constituted beliefs about what is seasonally appropriate childrens activity. To foster a healthier and more sustainable life for children, outdoor play needs to become convenient all-year-round in all locations.
