ATLAZUL is an alliance between the maritime regions of Alentejo, Algarve, Andalusia and Galicia to promote the specialization of the cross-border area in Blue Growth. The general objective of the Atlazul project is to identify challenges, opportunities and generate networks that promote the specialization of the cross-border area in terms of Blue Growth, as well as to develop innovations in the field of Blue Growth policies related to metabolic processes that provide new solutions with digital support, and the improvement of terrestrial and marine knowledge. The Alentejo-Algarve-Andalusia Euroregion, with the additional participation of Galicia, aims to deepen the opportunities by promoting Blue Growth policies that explore the synergies derived from constructive relations between the different sectors operating in this area.
