Definitions used to guide the systematic review (risky play environments).

Risky Play Environment Environment that affords or accommodates risky play behaviours [69].
Affordances Features of the environment can enable and invite children to engage in certain types of play behaviours [70]. Affordances are unique for each individual and can be influenced by personal characteristics (e.g., strength, fear) and other features that may inspire or constrain actions (e.g., trees with low branches afford climbing).
