Recent horrible incidents of child abuse or child killing make every morning very sad and every night very traumatic. Parents who have child, can't sleep well and working women are always in a worry, is her child is ok! I have talked to several parents (around 20) who find themselves very helpless and have restricted their children's movement. They don't allow their children to go any place with their friend as the outside is full of human like beast. This social unrest affects the way we expect our children to be nurtured.
So we observe very little amount of children's in park, field and lake. It's obvious they have little facility for them in these urban open spaces but its also because this places are overcrowded with teenagers and adults. Huge traffic flow in cities are also a threat to children's free movement. So in designing cities, children's space need to be carefully designed.
