"Some scientific studies have shown the importance of children´s play and activities in free air. Whether in cities or in the countryside, time and space are of significance to children´s development as human and cultural beings. "Children´s Tracks" is a method developed in Norway during the last decade for gaining knowledge of children´s land-use by mapping children's land-use patterns in municipality planning. The importance of making children´s interests visible in the municipal planning process is well known in Norway. On the national level we have National Policy Guidelines for Children and Planning. The Norwegian Planning and Building Act is in accordance with these guidelines. Both are considered as implementations of the UN Convention on the Child´s rights."
