This book – Complexity and Territorial Development – tells the story of how academic staff and students at the Van Hall Larenstein university of applied sciences deal with complexity and planning in education and research. It is intended for everyone who is involved in complex projects, but in particular for current and future students at the university who will be trained in how to handle complex projects. In this book we want to show why planning has become complex, what theories about this subject are relevant, and how this fits in with the practical experience of staff and students.
