Climate Action

Waking up early and going into the field on a small fishermen's boat, while the sun is rising behind volcano tops. That's how days started for PhD student Silke Tas during her two month fieldwork in Indonesia. The rest of her days were less idyllic: they consisted mostly of treading through the mud to get the right measurements for her research. She studies the workings of coastal sandbanks that give a chance to mangrove forests to restore, so that the forests can, in turn, prevent coast erosion.

Earth observation is experiencing a golden age: satellites are providing us with an unprecedented wealth of data. Climate researcher Stef Lhermitte is making good use of this, because however effective our models may be, they still contain plenty of uncertainties.

For months hydraulic engineer Patrick Oosterlo has been waiting for a heavy storm. One that can truly test his equipment that was installed in and on a dike on the coast of the eastern Wadden Sea. He needs high waves and strong winds to decide: is this dike high enough?

Air pollution, and the associated premature deaths, are strongly affected by distant emission sources. In the US about half of the premature mortality occurs outside the state that produces the emissions.

Rivers take vital water to villages and cities, but unfortunately they also carry harmful plastic to oceans. In order to prevent this, we need to find out exactly where the plastic comes from and how it is distributed over time and space. Counting plastic waste items from bridges is one of the commonly used methods to do this. But then how can the huge amounts of plastic in inaccessible places be pinpointed? Master student in Hydraulic Engineering Marlein Geraeds spent her internship at The Ocean Cleanup investigating how to monitor plastic waste in Malaysia’s River Klang by means of drones.
