This volume gathers a selection of research contributions on Strategic Environmental Assessment (SEA), including theoretical and methodological studies and real-world case studies. It sheds new light on the respective steps in the procedure defined in the SEA Directive from theoretical and operational standpoints, intended to enhance the sustainability of plans and programmes adopted by local, regional and national authorities. Improving the legitimacy and transparency of decision-making in the field of environmental management was one of the goals that led the European Commission (EU) to adopt Directive 2001/42/EC on the assessment of environmental programmes' effects. This book provides a multidisciplinary approach to SEA, and addresses the demand for policies and strategies to strengthen resilience through concrete measures to reduce energy consumption, mitigate pollution, promote social inclusion and create urban identity.
