Burgas is the second largest city on the Bulgarian Black Sea coast and the fourth largest national city, being one of the most important tourist, cultural, industrial and transport centers in Bulgaria. Due to its importance at the territorial level, it presents a high level of development of infrastructure and economic services, being at the same time one of the most important ports of the Black Sea.

The complementarity between port and airport functions leads to the definition of the city as an important intermodal hub both at the local, national and cross-border level, functions that increase the dynamics of spatial activities.

The city is surrounded by numerous protected natural areas (land and water) recognized for their biodiversity and their resources.
The case study will folow the interaction between land and sea with a special focus on the biodiversity and the impact of infrastructure on maritime space.
