ABSTRACT
This chapter presents the theoretical debates based on public documents and scientific contributions around the triple node of sustainable development, culture, and small and medium-sized cities (SMCs). In the last three decades, globally raising social insecurities and ecological threats have brought about the issue of sustainable development as a universal concern, called by some the "Green Revolution". On one hand, social and political scientists have been increasingly dealing with various aspects of endangered human life, culminating in the theory of the risk society that began to produce globally greater risks than wealth. There are three important aspects of new holistic developmental model: the imperative of limits, changed developmental aim, and differentiated approaches to achieve these ends. The ever-growing influence of culture for sustainable development is realized at different levels of European urban policies and practices, which can be called "European urbactivism". The idea of Europolis gives hope, based equally on the continuing European urban traditions and the capacity for their innovation.
