Clamouring to “ornamentalise” and reinvent...t

'One curiously geographical form through which [the] circulation of new globalising, cultural spatialities takes place is the artificial island. The worldwide phenomenon of the artificial island has become a key defining imaginary and material form of 21st-century development visions clamouring to “ornamentalise” and reinvent, their urbanising coastlines.'

I couldn't understand the emphasized phrase, can someone rephrase it? Thanks in advance.
