Cities overshadowed by power struggles over territory pose tremendous challenges to the implementation of planning and orderly development, in particular, when the contest concerns sovereignty. In such cases, conflicting citizens are in constant search for security and cast loyalty around narrow interests, making it extremely difficult for planning to accommodate inter-community cohesion. Using an in-depth critical examination of Nicosia master Plan by way of illustration, this book argues that this context of acute division requires a form of planning that successfully addresses cohesion, inclusion and socio-economic welfare. Underpinned by the author's engagement with four cultures - English, Greek, Palestinian and Turkish - it empirically tests how effective the collaborative planning approach is in such a divisive context. In doing so, it adds to the debates on collaborative planning by reworking its theoretical perspective. It also argues that conflicts are not necessarily always negative and which should be removed in an effort to arrive at democratic decisions, but can actually be helpful in some stages of the planning process.
