8 November 2011 – Today is World Town Planning Day in more than 30 countries and an opportunity to address how planning could assist an “overstretched and overcrowded” planet live more sustainably, Planning Institute of Australia chief executive officer Kirsty Kelly said.

“Modern planning has to look at ways to make growing populations and cities work in a sustainable manner,” Ms Kelly said.

“World Town Planning Day, also know as World Urbanism Day, was founded in 1949 by a graduate at the Institut d’urbanisme in Paris, the late Professor Carlos Maria della Paolera.

“The idea was to promote good planning and highlight the role it plays in creating liveable communities and to draw attention to the social, environmental and economic impact from the development of our cities and territories,” a PIA statement said.

“The United Nations estimates the world reached a total population of 1 billion in 1804. Some 123 years later in 1927, it was at 2 billion. Just 33 years later in 1960 it was 3 billion. It hit 4 billion 14 years later in 1974. By 1987 it had reached 5 billion. Then 6 billion in 1999. And now 7 billion.”
