So at mit, they are studying the fundamental physics and engineering of it. so, like, trying to understand, how does a sandbank actually form? and that, we've done through satellite imagery and drone footage and, you know, talking to other locals around here, trying to understand the historical data of how sandbanks appear and disappear. five years ago, sarah partnered up with the scientists from the self—assembly lab at mit, the massachusetts institute of technology in the us. the growing islands project is about naturally accumulating sand in the ocean without sculpting or pumping sand, bu...

Of the pacific ocean and the movement of the sand. they place different—shaped objects in the environment to see which is the best at sand—gathering. our hypothesis is that the reason sand accumulates in certain areas and not others is due to the relationship of the geometry underwater and the force of the oceans. and so, what we do is we design different geometries, we test them in the lab, we see which geometries accumulate more sand, and then we implement those at full scale in the maldives. this is the beginnings of a new island built on sandbags. and you can see where the sand has acc...

To the seasons and the ocean's forces. and that really influences the way that the people live and adapt. in fact, you can see that the locals have really made the most of this particular idyllic paradise. so we have two seasons predominantly in the maldives. one is the southeast and the northwest monsoons. and, you know, literally, during these seasons, we say we see sand shifting and we see sand eroding from one end and then building up on another end. and as a physicist, i thought, you know, can we use this? sarah dole is sri lankan, but has been living in the maldives for over a decade, an...

And as a physicist, i thought, you know, can we use this? sarah dole is sri lankan, but has been living in the maldives for over a decade, and has dedicated herself to studying this natural shift of sand to find a way to create islands sustainably. so first of all, you know, we had to study the fundamentals. so at mit, they are studying the fundamental physics and engineering of it. so, like, trying to understand, how does a sandbank actually form? and that, we've done through satellite imagery and drone footage and, you know, talking to other locals around here, trying to understand the histo...

This is the beginnings of a new island built on sandbags. and you can see where the sand has accumulated using the forces of nature. it's been here for about two years. it's 20 metres long, it's about four metres wide and about 1.5 metres above the sea bed. another half—metre and it should pop up above the surface and hopefullyjust keep growing. each time we go, we try different materials, different construction techniques. the reason for that is because we want to try to make it as scalable as possible. because this is a global problem, it's not only focused on the maldives. so if you reall...
