Climate Action

There is no doubt that the anthropogenic emissions of greenhouse gases are changing our living environment. Climate change is in our hands. We need to both work on limiting it as much as we can (mitigation), but we will also have to learn to adapt to new circumstances. TU Delft will harness its innovative powers to support the world-wide transition to non-fossil resources, and adaptation of the living environment to the consequences of global warming.

The problem is complex and urgent – but we have no other choice than to be optimistic and use all of our capacity to face the challenge, through our education programs and our research.

In the Climate Action research programme, we start from four themes we consider to be paramount for future Climate Action:

The TU Delft vision on Climate Action is deeply founded in preceding decades of university wide climate action research. The goal of the Climate action research programme is to build on current strengths and identify the areas where there is a need to strengthen our capacities to keep up our (inter)national reputation as climate action university.

Water in the sky

Water in the sky

Water is of vital importance for human survival. Human activity influences the way water moves around the earth but the complexity of the system is such that it is hard to tell how far-reaching its effects really are. Scientists like Lan Wang-Erlandsson are working hard to chart the earth’s water cycle with more precision. Wang-Erlandsson, who grew up in Sweden, became involved in this area of research when she worked as a volunteer at the annual World Water Week conference in Stockholm.

Water stress in the rainforest

Water stress in the rainforest

How much water is intercepted by the canopy of a tree? That was the question PhD candidate Tim van Emmerik had to find an answer to in order to gain a better understanding of the earth’s water cycle. But how to go about it? Fitting every leaf with expensive equipment was not an option, so Tim and colleagues had to develop smart measuring methods to infer the right data. And learn to climb trees, in the Brazilian Amazon.

Hot topic: Green Roofs

Hot topic: Green Roofs

Green roofs are hot! Roofs completely covered in plants are becoming a familiar sight in our cities. After all, what’s not to like? They offer a home to birds and insects, and because the plants hold on to moisture they cool down the city in summer. And, as an added bonus, it’s clear for everyone to see you’re doing your bit for the environment. Except that Anna Solcerova’s PhD research project (Department of Water Management) shows that these roofs are having quite a different effect.

Leapfrogging towards sustainable palm oil

Leapfrogging towards sustainable palm oil

With palm oil being the most widely used vegetable oil in the world, the industry is likely to stay with us for the foreseeable future, despite its controversial reputation of pollution, deforestation and ignoring the needs of local communities. “The palm oil industry is only expanding, so doing nothing is not going to solve the problem,” says Dr Ralph Lindeboom of the department of Sanitary Engineering. Together with the PhD-researcher and Delft Global Fellow Saqr Al-Muraisy , he aims to help make the industry more sustainable for both the environment and local people.

Mangroves caught in the middle

Mangroves caught in the middle

In a channel at TU Delft’s Water lab a stream of purple-tinted water makes its way past thousands of small wooden pegs. The water was dyed by PhD-candidate Son Truong Hong, who is closely observing the flow with an empty bottle of paint in his hands. This test forms part of his research into the importance of the mangrove forests in the Mekong Delta estuaries. Son is fascinated by the tangled roots of these extraordinary trees. What is the mangrove’s role in preventing river bank erosion? And, most crucially, how much of the mangrove forests needs to remain to support a healthy ecosystem?

Greenland ice losses rising faster than expected

Greenland ice losses rising faster than expected

Greenland is losing ice seven times faster than in the 1990s and is tracking the IPCC’s high-end climate warming scenario, according to the Ice Sheet Mass Balance Inter-comparison Exercise (IMBIE) Team.

Weather alarm: chance of sudden death

Weather alarm: chance of sudden death

Rain radar, weather apps, satellite images and code yellow (weather warning code in NL): we are all fascinated by the weather. Nevertheless, even the experts know less about it all than we think, particularly when it comes to the weather at night and in cold areas. Bas van de Wiel wants to change that. He intends to use his ERC Consolidator Grant to give the underappreciated nights a bigger role in weather and climate models.

Continuously scanning the coast

Continuously scanning the coast

Hotel Atlantic in Kijkduin overlooks the North Sea. On its deserted roof a state of the art laser scanner is monitoring the beach every hour, 24/7. Sander Vos hopes the resulting data will provide insight into the restoration of the coast after a storm when part of the beach and fore dunes disappear into the sea. With the information provided by the scanner he and his TU Delft colleagues hope to become ‘coastal weathermen’ who will be able to predict exactly how the beach behaves after a storm.

Observing rain at street-level

Observing rain at street-level

Heavy showers sweep over cities, flooding streets and houses when urban drainage systems get overwhelmed. Ever-increasing pressures from climate change, population growth and changes in land use augment the risks of urban floods. We’re currently unable to predict accurately where and when flooding will occur. Forecasting is particularly tricky in densely populated cities, where rainfall observations are scarce, spatial variability in land-cover is high and flood response to rainfall is very fast. Researchers want to use radar and innovative ground sensors to observe rainfall and water levels more accurately and at higher density to improve the reliability of hydrological predictions . Marie-Claire ten Veldhuis is trying to gather this information in various projects. Her objective is to unravel the complexity of urban hydrological response, to be able to predict with greater accuracy when and where streets will flood.

Water lust and nuisance

Water lust and nuisance

Reliable tap water, proper waste water treatment, and dry feet. That’s what people in the Netherlands expect and are accustomed to. However, flooded homes, sewer overflows and impassable roads occur with increasing frequency. The Randstad conurbation has suffered from severe water issues in recent months for instance. The KNMI [Royal Netherlands Meteorological Institute] has predicted that the number of extreme showers will further increase in the 21st century due to global warming. The water infrastructure in our urban areas isn’t built to accommodate this, warns Professor Jules van Lier. He argues in favour of smarter solutions and a new paradigm for our Urban Water Infrastructure.
