Place and mobility integrate the social and spatial dimensions of the environment that we live in and move between. As increasing numbers of people around the world are moving, both within national borders and internationally, a secure place for people on the move is essential, underscoring the importance of planning for rapidly growing cities that can integrate and support rural-urban migrants as well as the urban poor. Yet, the scale of the human population living day-to-day without a safe or reliable home underscores the urgency of enhanced global attention to human security. A secure place is essential for human development, as human security – that is, freedom from hunger, fear, violence and discrimination – is a pre-condition for the development of children, and the creative growth of all persons.
