Currently, many children live in extreme poverty and high-risk neighbourhoods, who are among the most vulnerable group in society. However, they are the link between the past and future generations. Accordingly, planning for neighbourhood sustainability as the first public place for interactive experiences of children, inside the framework of a child-friendly city (CFC) approach, could provide an opportunity for all children to meet their desires. The paper aims to create sustainable neighbourhoods through the participation of children. This study is applied research that was conducted through the qualitative and quantitative methods based on secondary data, library-documentary and fieldwork. Moreover, participatory approaches such as painting, pictorial questionnaire and interviews with 141 children, aged 10–14 years on their favourite spaces, activities, and vehicles have been used by means of cluster random sampling method. The results indicated that home, playing with others, and cycling are most favoured by the children regarding the sustainability indicators in the neighbourhood.

Green spaces are foundational to urban social sustainability and solidarity since they are accessible to all citizens without discrimination or restriction. Such spaces enable social interactions, and as places of convergence offer a sense of belonging, participation and social sustainability. Green spaces also can directly contribute to SDG 11 “Sustainable cities and communities". This research investigates the effects of urban green spaces on the promotion of social sustainability in a case study of Tehran, Iran. By adopting both quantitative and qualitative methods, this study employs a Strengths, Weaknesses, Opportunities, and Threats (SWOT) analysis in combination with an Analytic Hierarchy Process (AHP) implemented in Expert Choice software and focus group discussions. Results revealed that in order to improve social sustainability, the risk of growing insecurity in green areas among citizens and the spreading of disease due to proximity to dangerous sites were the highest overall priority values. In contrast, the lowest overall priority values belonged to the factors of sports equipment for physical activities and intellectual games and lack of attention to trees and seasonal flowers in some obsolete green spaces.
