Despite the non-territorialised strategic goals of the EU 2020 Strategy, the long-term aim of EU Cohesion Policy to promote harmonious development of the European territory - social, economic, and 'territorial cohesion' - remains a central goal of achieving a more cohesive EU territory. This book examines the 'territorial dimension' of EU Cohesion Policy, specifically assessing territorial impacts at the various spatial levels, engaging theoretically and empirically with the notion and role of the 'territorial dimension' within a strongly fragmented EU policymaking process, and examining more generally EU Cohesion Policy, as the main driver of the EU territorial development process. It provides an updated and fresh theoretical discussion on the precise meaning of the 'territorial dimension' of policies and the relatively recent EU policy evaluation technique, known as 'Territorial Impact Assessment' (TIA). Assessing the history, relevance, efficiency and effectiveness of these procedures, it presents several empirical findings on the implementation of specific territorial-focus and place-based financial instruments, as part of the Territorial Agendas and the EU goal of achieving a more integrated, territorial approach. This text will be of key interest to scholars, students and practitioners of spatial planning and cohesion policy, European sector policies and European spatial planning, and more broadly to European and EU studies/politics, regional economic geography and public policy.
