This study aimed to investigate research articles that relate to education for sustainability, primarily in early childhood, in order to describe to what extent a holistic perspective on education for sustainability has been applied, and how the social dimension is conceptualized. The review comprised research articles in Nordic Journals of Education, International Journals of Early Childhood Education, and International Journals of Education/Environmental/Sustainability education. The findings disclosed that researchers within the field of education for sustainability acknowledged, to a large extent, environmental, economic, and social aspects, and thus applied a holistic perspective. This review shows, however, that even if the social dimension were conceptualized as strongly related to topics such as social justice, citizenship, and the building of stable societies, few articles have investigated diversity, multicultural perspectives, or migrant children's situations in the context of early childhood education for sustainability. This review discloses that the concept of belonging is rarely used in connection to migrants and refugees in research on early childhood education for sustainability. A further argument encourages the inclusion of these aspects in further research which claims social sustainability.

With the aim of developing new knowledge on inclusive practices for young children in early childhood education, the following research question was explored: what characterises young children's negotiations of belonging and togetherness in a diverse peer group in kindergarten? Data from field work in a young children's group in a multicultural kindergarten in Norway formed basis for the present study's analysis, which was conducted within a culturalhistorical framework. The findings revealed that the two-year-olds' everyday institutional lives were influenced by features in the peer culture and characterised by fleeting moments of caring and sharing, shared joint experiences and ongoing negotiations of mutual bonds, hierarchies and group boundaries. Although the findings did not reveal any differences along ethnic or cultural lines when it came to the two-year-olds' negotiations of belonging and togetherness, the fact that the peer culture already at this age included the application of hierarchies and symbol systems, calls for kindergarten teachers' awareness in order to secure inclusive practices for young children.
