This dissertation investigates the efforts of a temporary organization, or a project, to assemble a set of diverse stakeholders to deliberate and chart a territorial plan for the Black Sea coastal region in Bulgaria. The project lasted two years and tried to apply the integrated method of regional planning developed in the area around the port of Rotterdam. It was led by a Dutch consultant and a team of Dutch and Bulgarian environmental experts. The main question the dissertation addresses is how a temporary organization operates in an environment that provides little support for its actions.

Project ecologies comprised of personal and organizational ties built around industries and geographical areas facilitate their work. Usually the existence of such ecologies is assumed in research on organizations.
