Members of the civil society are challenged to solve prevailing social problems with innovative ideas and concepts. They try to provide alternatives to the current social system, their activities cover a wide range of different actions: A range from organized search for alternatives up to concrete creations of applicable ideas. An example for the latter is the Transition Town Movement, dedicating its efforts to build sustainable economic and social structures. The problem is, that civil society is not homogeneous, neither its motives for taking action, nor the staging and their strategies. The goal is firstly, to investigate the concept of civil society, its motivation for its active role as problem-solver. Secondly, the Graz Model for Integrative Change Processes is applied as a methodological instrument to evaluate strategies of the Transition Town Movement, using a case study approach. Starting point is a characterization of the modern society. People within national states are, due to effects of globalization, affected by fundamental challenges. Civil society cannot be defined in a uniform way, but actual challenges need more solidarity. In National States with a democratic political system, the idea of an active civil society is founded. Market forces are driven by regulatory principles, and cannot be separated from the civil society. Social movements are the relevant actors of the civil society. Investigating five active civil society organizations is the empirical research part and closes the theoretical approach. It leads to the evaluation of strategies of the Transition Town Movement, in terms of five basic principles. A shared vision, distinct network structures, an active participation as well as integration of education and research within social movements contribute to the potentiality to generate social cohesion and enlarge the chance of change towards sustainability.
