I1 - Collaroy-Narabeen is a 3.6km beach located on the Northern Beaches of Sydney's coastline, it is world famous with surfers. Properties built across the entire back-beach are now at the forefront of climate change.

I2 - Pago Pago Harbor is what remains of the volcanic crater that formed the main island Tutuila of American Samoa, South Pacific Ocean.

 

With an average depth of 30 fathoms (180 feet, 30 m) it is wide and deep enough to cater to any size ship or vessel. Several villages surround the harbor, including Utulei, Leloaloa, and Aua.

I3 - Barranquilla – Ciénaga, Columbia. This is one of the most famous coastal erosion hotspots! Named the “19 km sector”, located on the main road between Barranquilla and Cienaga.

 

This 3 km stretch of road has experienced massive changes in the last 20 years, with erosion rates that have reached 21 metres per year. Coastal erosion affects two significant ecosystems of this region: The barrier islands system of the Cienaga Grande de Santa Marta and the Pajarales Lagoon Complex.

I4 - Katwijk aan Zee, South Holland. The Netherlands is a low lying country. More than half of it lies below sea level. Without dykes and dunes, the people living there would be flooded.

I7 - Playetas Baru, Columbia.  The recent shoreline evolution on the Playetas sector has been influenced by a strong erosive behavior that makes it one of the most tragic examples of erosion and loss of land along the Caribbean coast of Colombia.

I8 - Chittagong, Bangladesh.  Chittagong; officially called Chattogram, is regarded as the largest industrial and commercial port in Bangladesh, and one of the central ports in the Indian Ocean.

Because of this, many migrate with the hope of finding work, resulting in an estimated population of over 5 million. However, with the effects of climate change increasing, and the extreme population size, the consequences of flooding in Chittagong are far beyond manageable.

I9 - Highcliffe, Dorset. Highcliffe Beach is a popular tourist destination on the coast of Dorset, Southern England. The town of Highcliffe extends right to the modern-day cliff edge, and includes the historic Highcliffe Castle, built in the 1830s. The cliffs have a long history of extreme erosion and many coastal management strategies and coastal defences have been implemented over the decades to try and slow this erosion down.
