We are building more islands than ever before. In the latest edition of our photographic series Anthropo-Scene, we explore the striking results of humanity's attempts to colonise the world's lakes and oceans with new land.

Hundreds of years ago, the Lau people of the Solomon Islands built around 80 artificial islands in a lagoon, placing bits of coral and rock into the water, piece by piece. It took them centuries.

Throughout history, humans have sought to create dry land within lakes, rivers and oceans, which they could then populate. But the 21st Century has brought a new ambition – and perhaps a touch of hubris – to this endeavour.

We are living in an "age of islands", according to the social geographer Alastair Bonnett of Newcastle University, UK. "New islands are being built in numbers and on a scale never seen before."

This new generation of islands are bolder, grander – and potentially more damaging – than anything our ancestors constructed, writes Bonnett in his book Elsewhere: A Journey Into Our Age Of Islands.

The geographer visited human-made islands all over the world, exploring a variety of constructions. Giant artificial archipelagos, created by pouring millions of tonnes of sand into the ocean. Concrete-coated "Frankenstein" atolls, designed to consolidate military and political power. And dizzyingly tall oil rigs extending hundreds of metres down to the seafloor.

While some artificial structures have been reclaimed by nature, that process takes time. Often, there's little life beneath the waters surrounding man-made islands. "All too often artificial islands are dead zones. Trying to make them live again is hard work," writes Bonnett. In places like the South China Sea, "once pristine and untouched reefs…have been horribly mutilated: squared off and concreted over".

See more from the Anthropo-scene series:

  • Concrete: The material that's 'too vast to imagine'
  • The 'battery terrain' of South America
  • The scarred landscapes created by humanity’s material thirst

But nonetheless, Bonnett found himself drawn to these artificial creations, to try and understand how they were built, and why they came to be. Whether you approve of them or not, they will tell future generations a story of how humanity saw itself in the early Anthropocene.

To understand what the age of islands looks like, scroll down to take a brief tour of some of the most visually striking and impactful examples from around the world – taking in the Gulf States, the seas off Asia, and the coasts of the UK and US.
