This systematic review synthesised evidence on associations between nature-based early childhood education (ECE) and children’s social, emotional, and cognitive development. A search of nine databases was concluded in August 2020. Studies were eligible if: (a) children (2–7 years) attended ECE, (b) ECE integrated nature, and (c) assessed child-level outcomes. Two reviewers independently screened full-text articles and assessed study quality. Synthesis included effect direction, thematic analysis, and results-based convergent synthesis. One thousand three hundred and seventy full-text articles were screened, and 36 (26 quantitative; 9 qualitative; 1 mixed-methods) studies were eligible. Quantitative outcomes were cognitive (n = 11), social and emotional (n = 13), nature connectedness (n = 9), and play (n = 10). Studies included controlled (n = 6)/uncontrolled (n = 6) before-after, and cross-sectional (n = 15) designs. Based on very low certainty of the evidence, there were positive associations between nature-based ECE and self-regulation, social skills, social and emotional development, nature relatedness, awareness of nature, and play interaction. Inconsistent associations were found for attention, attachment, initiative, environmentally responsible behaviour, and play disruption/disconnection. Qualitative studies (n = 10) noted that nature-based ECE afforded opportunities for play, socialising, and creativity. Nature-based ECE may improve some childhood development outcomes, however, high-quality experimental designs describing the dose and quality of nature are needed to explore the hypothesised pathways connecting nature-based ECE to childhood development (Systematic Review Registration: CRD42019152582).

Risk aversive perceptions and practices among ECEC practitioners and parents have proven to be an important reason for the decline of young children’s opportunities for free outdoor play. Yet, there are also cultural differences in the perception of children’s risky play. This study aims at examining the factors that ECEC practitioners and parents experience as barriers for children’s outdoor play, especially those associated with risk. ECEC practitioners and parents in five different European countries (Greece, Portugal, Estonia, Croatia and Norway) received questionnaires about their perception of children’s outdoor play. The sample consists of 32 ECEC practitioners and 184 parents. Results show that parents and ECEC practitioners from Norway are less risk aversive to children’s play than those from the southern European countries. Traffic is a barrier for outdoor play among parents from all countries (above 50%), and stranger danger is particularly noticed in parents from Greece (80.6%) and Portugal (62.9%), whereas in Norway this value is only 13.3%. The mean average age from which parents allow their children to play outside is quite different between the participating countries, ranging from 5.8 years in Norway to 11.8 years in Greece. In total, fear of children getting injured and adults’ own concern/anxiety are only mentioned as barriers by 9.4% and 3.1% of ECEC practitioners, respectively. Lack of play spaces (74.3%) and poor play facilities (80%) are also considered obstacles to letting children play outside by Greek parents, whereas Portuguese ones emphasized media alerts (61.3%). Our results suggest a differentiated approach between countries to tackle the reported barriers to children’s outdoor risky play.

Through development, a child's varied movement contexts provide different opportunities or affordances for action that are fundamental to promoting motor competence. Although home is the primary environment for infants, as children age, school and sport environments gain importance. Studies focusing on affordances for motor behavior in children have mainly addressed the home microsystem, providing an incomplete picture of affordances across different settings, particularly later in development. Here, we undertook a narrative literature review of various affordances for children's motor development. This review revealed that prior studies of school and sports contexts have not specifically focused on those environmental properties that promote or hinder motor learning opportunities, meaning that future research should assess these relationships through manipulations of environmental features in these different microsystems.
