The 2012 Tech4Dev International Conference will look at how science and technologies can support both sustainable development and the Millennium Development Goals (MDGs) in developing and emerging countries. It aims to bring researchers and practitioners together to bridge the gap between the two communities, focusing on collaboration, methodologies, instruments and policies that could be used and/or encouraged. The possibility of a universal tool and policies for science, technology and innovation that could be of assistance in future collaborations will also be introduced. Participants from developing countries are especially encouraged to attend, in order to make the conference as inclusive and diverse as possible.
