Abstract
The conviction that inspires the 'Landscape fragmentation theories and application project' is that today more than ever, it is vital to study and invest in issues related to the fragmentation of the landscape. The Landscape Fragmentation, i.e. the process in which habitats are divided into increasingly small and isolated portions, cannot be analyzed from a mono-specialist perspective. On the contrary, its study involves the development of multidisciplinary insights into both urban planning and environmental sciences and the necessary synthesis into a single overview. A special thanks for the development of this three years PhD goes to the Miur, which made available the grant destined to Innovative Doctorates with industrial characterization, in implementation of the measures in support of human capital provided by the PON Research and Innovation 2014-2020. This type of PhD has involved a classic period of research at a foreign university, a period of study and research at a company that deals with activities related to the project as well. As far as my project is concerned, I have carried out my research activity both abroad, at the University of Cardiff, and at the studio of associated professionals specialized in territorial, landscape and environmental planning "Criteria s.r.l.", based in Cagliari. During the six months spent at the School of Geography and Planning, University of Cardiff (UK), I was able to deepen my knowledge of environmental policy by attending the course "Principles and Practices of Environmental Governance", a module divided into three main components complementary to each other.The "Governance Tools" have been explored through a detailed overview of how particular environmental governance mechanisms are put into practice and tested "in the field" on the basis of international case studies.
