The Nitrogen Crisis has become a focal point for the global community, with the related European policy stirring uncertainty in the agricultural sector. This political unrest has been clearly manifested in the Netherlands, while natural areas remain exposed to high emission levels. Society calls for systematic solutions to the nitrogen issue...

Nitrogen is an essential element of planetary life. Yet, human actions create such a surplus of its derivatives like ammonia (NH3) and nitrogen oxides (NOx) that the naturally occurring amounts doubled, causing a cascade of environmental and societal problems.<br/>Our research studies dairy farming in North-West Europe with a focus on the...

The Netherlands has created a large nitrogen pollution problem in its soils, which is harming biodiversity. By intensifying and industrialized farming, by importing animal feed for dairy production and fertilizer for crop farming, too much nitrogen has accumulated in the soil. Consequently, ecological processes are disturbed due to...

The Netherlands, renowned for its flat landscape and strategic location at the confluence of major rivers, combined with fertile soil and a mild climate, boasts optimal natural conditions for agricultural production. However, the success of the Dutch agricultural sector and its developments has significant implications for biodiversity, as...

The Netherlands holds the title of the world’s second-largest exporter of agricultural goods, primarily due to Wageningen University’s pioneering research and innovation. However, this success has led to significant challenges. Intensive farming practices have strained resources and disrupted local water and soil cycles, sparking protests from...

There is an imbalance in the nitrogen cycle, mainly caused by an increasingly intensive agricultural sector. This leads to the degradation of nature and the loss of biodiversity. Measures have been taken at European level to reduce the amount of nitrogen emitted by the agricultural sector, but this has caused a backlash as farmers in many...

Ammonia is a precursor in fertilizer production and a potential carbon-free energy carrier, which is essential for the energy transition to more renewable energy sources. To that end, the current fossil fuel based method of industrial ammonia production through the Haber-Bosch process should be replaced by electrochemical ammonia synthesis....

Stremming, Luca (author)
Aviation is an important contributor to anthropogenic climate change. As indirect greenhouse gases, nitrogen oxides (NOx = NO + NO2) add to the Effective Radiative Forcing (ERF) induced by aircraft emissions. This work addresses a better understanding of emission mitigation by investigating dependencies between engine parameters and emitted...

Pletzer, Johannes (author)
At speeds roughly between five and ten thousand km/h, hypersonic aircraft offer the promise of an extremely fast means of transport. Growing concerns about climate warming, however, direct attention to sustainability. This thesis focuses on atmospheric composition and radiation changes by considering a range of individual hypersonic aircraft...

Global passenger air traffic has doubled in the 13 years prior to 2019, and is expected to double again over the next 20 years or so. Growing demand for aviation is met by a corresponding increase in jet fuel being burned by aircraft, releasing multiple pollutants into the atmosphere. Besides disturbing the Earth’s radiative balance, these...

Increasing wildfire frequency, a consequence of global climate change, releases incomplete combustion byproducts such as aquatic pyrogenic dissolved organic matter (DOM) and black carbon (DBC) into waters, posing a threat to water security. In August 2022, a series of severe wildfires occurred in Chongqing, China. Samples from seven locations...

Constructed wetlands (CWs) have been proven to effectively immobilize plastic particles. However, little is known about the differences in the impact of varying sized plastic particles on nitrous oxide (N<sub>2</sub>O) release, as well as the intervention mechanisms in CWs. Here, we built a lab-scale wetland model and introduced plastic...

Kloppenburg, Noor (author)
To limit global warming to 2 °C or below, the IPCC emphasizes the need for large-scale carbon dioxide removal (CDR) alongside emissions reductions. There is a growing recognition of ocean-based CDR techniques and expanded research is needed. This thesis investigated the long-term (&gt;100 years) carbon sequestration potential of enhancing the...

van Manen, Menno (author)
The Netherlands is a country with a history of human activity along the coast to ensure water safety. In the 1990's a new approach to coastal management was adopted that allowed for more experimentation in the Dutch dunes. Since then a slew of different types of projects have been undertaken, one of which is the construction of foredune blowouts...

Simon, B.G. (author)
Spin waves are the elementary excitations of magnetic materials. They are interesting because of their rich physics and potential role in low-dissipation information technology. To better understand spin-wave transport and explore new ways to control it, this thesis focuses on developing magnetic-imaging techniques based on the single spin of...

Vlierboom, Alexander (author)
Ammonia (NH3) is a bulk commodity chemical known for its large production volumes and application in the global fertiliser industry, and is more recently being explored for its role as a sustainable energy vector. The industry standard ammonia production method is the century-old Haber-Bosch (HB) process, which is power by fossil fuels, and is...

For the last decades, technologies, new agricultural trade policies, environmental restrictions, high pressure through economic competition in combination with a sharp competition of land lead to the development of intensive farming. As a result, patchy landscapes have been replaced by monofunctional, homogeneous agricultural landscapes that...

A transition is needed within the current agricultural sector. The intensive food production emits a significant amount of greenhouse gases, but also generates a nitrogen surplus. Consequently, biodiversity and soil quality have been decreasing dramatically in recent decades. One way of achieving a more sustainable food system is through...

Nature is declining rapidly. Recent research connected the natural decline with the intensive and monocultural way of dairy agriculture that is happening in North-Western Europe. As a result farmers are forced to stop and are left without a vision for their future. A change in the practice of dairy farming is necessary to reach the goals of the...
