Developing Astronomy Globally Astronomy worldwide needs to be developed in three key areas: professionally (universities and research); publicly (communication, media, and amateur groups) and educationally (schools and informal education structures). The focus is on regions that do not already have strong astronomical communities. The implementation is centred on training, development and networking in each of these three key areas. This Cornerstone project is using the momentum of the IYA2009 to help establish and enhance regional structures and networks that work on the development of astronomy around the world. These networks support the current and future development work of the IAU and other programmes and ensure that developing regions can benefit from the IYA2009 and the work of the other Cornerstone projects. It also addresses the question of the contribution of astronomy to development. The efforts of this cornerstone project feed into the IAU Strategic Plan.
