The requirements for engineering education are changing. Sound technical knowledge is still the basis of the engineering profession but multi-sectoral skills are becoming increasingly important. In the Baltic countries, increased environmental and socio-economic problems have made it clear that narrow curricula are not sufficient. Tampere University of Technology (Finland) and Tallinn Technical University (Estonia) have jointly organized postgraduate courses in water and environmental management. Much emphasis has been placed on economy, policy, management and environmental issues. When the participants come from several countries and their background education is not only engineering, very interesting and useful interdisciplinary discussions have been experienced.
