In the framework of the COP 21 of Barcelona Convention (Naples, Italy, 2-5 December 2019), Global Footprint Network co-organizes with Eco-union, IUCN-Med, Plan Bleu, and the French Ministry for Ecological Transition, a side-event on "Sustainable Coastal and Maritime Tourism to Tackle Environmental and Development Challenges in the Mediterranean Region." The side-event will be held on Tuesday 3rd of December, 18h-19h, at Sala Sirena, Castel dell’Ovo in Naples and will spotlight recent outcomes, tools, and lessons learned around the topic of Mediterranean maritime and coastal sustainable tourism. This event will share novel approaches and lessons related to sustainable blue tourism and its role in supporting biodiversity conservation and territorial development around the Mediterranean coast. It will also highlight recent opportunities and gaps identified in governance, policy-making, impact monitoring and management, while sharing innovative perspectives on how recent achievements can be capitalized and scaled to broader Mediterranean context in the framework of the Barcelona Convention and other multilateral or voluntary environmental agreements and commitments at global, regional, national or local scale. Alessandro Galli, Ph.D, Global Footprint Network Director of Mediterranean and MENA Regions, will address the Ecological Footprint and ecotourism. The Ecotourism Footprint Calculator is now available to measure the Ecological Footprint of ecotourism itineraries and create a proven sustainable experience. Register for the side-event here.
