The meeting of the Group has gathered ten participants from USA, Netherlands, China, Hungary, Australia, Russia, and Italy.

The first report of the Group has been published in April 2012:

  • 1. To highlight common Urban Problems.
  • 2. To give an overview of which Underground Solutions can be used to solve these problems.
  • 3. Aspects to be considered during the Decision Making Process in order to include underground solutions.

"ISOCARP welcomes this extremely timely and interesting report from ITA-WG20 on 'Urban Problems, Underground Solutions.' It is a very valuable resource for urban planners and all those working on urban problems and potential solutions, and will give them ample food for thought." Shipra Narang Suri, Ph.D. Vice-President, ISOCARP, and Manfred Schrenk, Vice- President and Treasurer, ISOCARP.
