Het witwassen van de gelden die worden verkregen uit cybercrime vindt in toenemende mate plaats met digitale betalingsmiddelen. In dit onderzoek wordt nagegaan hoe deze gelden worden witgewassen, welke actoren een rol spelen en hoe digitale betalingsmiddelen daarbij worden gebruikt.

De wereldbevolking is in de afgelopen eeuw exponentieel gegroeid, en daarmee ook onze behoefte aan energie en materialen. Willen we in de toekomst ook in welvaart leven, dan zullen we onze economie en consumptie radicaal anders moeten inrichten. Wetenschappelijk onderzoek laat zien hoe dat kan.

What is the effect of light at night on plant phenology and physiology, and how does this affect plant interactions with other species?

Als Europeanen minder vlees en zuivel eten, heeft dat grote gevolgen voor boeren. Nieuw onderzoek laat zien dat veel stallen en machines hun waarde kunnen verliezen. Met goed beleid zijn die verliezen te beperken. Dat blijkt uit onderzoek van Leiden, Oxford en Wenen.

Welke consumentengroepen hebben de grootste impact op de volksgezondheid en de planeet door hun voedingskeuzes, en hoe kunnen we deze inzichten gebruiken om de transitie naar duurzame eetpatronen te versnellen?

Welke schimmels leven in de historische gebouwen en collecties van de Universiteit Leiden, hoe beïnvloeden deze schimmels erfgoed en gezondheid, en hoe kunnen we ze beter begrijpen en beheersen?

To contribute to the body of knowledge aiming at a better coverage of ecosystem service assessment in LCA studies, this thesis dives into the challenges of incorporating existing ecosystem service methods within the impact assessment phase of the conventional LCA framework.

The book ‘Bestrijdingsmiddelen en Milieu' gives a transparent overview of facts and figures concerning pesticide use in the Netherlands and the impact of pesticides on the environment.

At the moment, over 350.000 chemicals are registered worldwide for production and use. Their application, however, may harm human health and the environment.

The project seeks to develop an eco-design framework for single-use medical devices and packaging

Freshwater and brackish water ecosystems are arguably the most vulnerable ecosystems on earth, due to concentrated human developments in and around them. The Pontocaspian (PC) region located at the border of Europe and Asia contains a variety of brackish water ecosystems and unique inhabitants, known…

Vinasse is a major by-product generated by the sugarcane biofuel industry. It is a source of microbes, nutrients and organic matter and often it is recycled as fertilizer.

In times of hardships or crisis, local people know how to deal with it using their resourcefulness. Although efforts are sometimes made by the government to help them, they are fully aware that community support is at least equally important.

International trade has played a major role in defining the modern global economy. Trade, however, entangles the environmental pressures of economic sectors, giving the illusion of environmental improvements, while the opposite may be occurring.

The expanding population and economic activity are driving up global energy consumption. Simultaneously, there is an urgent need to transition from fossil fuels to renewable sources to mitigate the climate crisis, primarily caused by fossil fuel combustion.

Mycorrhizas are symbiotic associations between soil fungi and most plant species.

This thesis pioneers diatom molecular identification and quantification through genome-scale methods, with four key aims: (i) reviewing DNA/RNA sequencing methods in aquatic biomonitoring to highlight their strengths and limitations;

Global Environmental Extensions Multi-Regional Input-Output (EE-MRIO) analysis is often used to analyze how changes in global and national demand for products lead to socioeconomic and environmental impacts at the national level.

There is accumulating evidence for an increase in severe global drought events. In particular, Europe experienced several severe droughts in 2003, 2015, and 2018 (unprecedented in the past 2,110 years). Such droughts have caused serious and far-reaching impacts on terrestrial ecosystems.

Organic amendments applied to agricultural fields can partially offset our carbon emissions to the atmosphere and improve the resilience of agriculture to the effects of climate change. Driving these benefits, however, are complex and poorly understood interactions between organic amendment properties,…

While ecosystems have concrete benefits for human society, these benefits are typically overlooked in decision-making.

The external tissues of plants and animals are colonized by microbial communities termed microbiota. When organisms are exposed to environmental pollutants, these substances will therefore encounter microbiota at the exposure interface.

Plant diversity is essential for us and our planet as it sustains the stability of our ecosystems, provides vital materials and food to us and supports many ecosystem services.

This thesis describes the role of pollution, specifically neonicotinoid insecticides, as an actor of the ongoing biodiversity decline.

Promotores: Prof.dr.G.R. de Snoo and Dr. R. Heijungs

To limit the effects of climate change, global average temperature since pre-industrial measurements are to be kept well below 2 °C preferably even at 1.5 °C.

The development of new environmentally sound technologies is seen as a key route towards achieving sustainability.

The transition to electric vehicles (EVs) reduces vehicle emissions to combat climate change. EVs raise concerns regarding the production of lithium-ion batteries and related emissions; while batteries can also provide energy storage services for the electricity system.

Wetland plants are distinguished from plants of other terrestrial ecosystems by their adaptations to specific habitat stresses, including waterlogged and flooding and the subsequent abundance of phytotoxic compounds.

A management strategy has been developed for field margins to reduce pesticide drift to non-target areas and to promote biodiversity on arable land. To this end, 3 and 6 m wide strips along the edges of winter wheat, sugar beet and potato crops have been left unsprayed with herbicides and insecticides…

The role of material production as a driver of environmental impacts is increasing, which calls for a better understanding of global material flows. This thesis explores the role of in-use stocks of products, buildings and infrastructure as a key driver of global material demand and discusses the implications…

Ethiopian wolves are endangered diurnal Afroalpine rodent hunters. I investigated the interaction between wolves, rodents and human land use in Borena Sayint National Park (BSNP), Abune Yosef and Aboi Gara in Ethiopia.

The main research question of this thesis was: Can nitrogen cycling on dairy farms on peat soil in the Dutch Green Heart area be improved by adapting management to the nitrogen supply from soil and by using other grassland species and crops without affecting milk production?

Novel entities may pose risks to humans and the environment. The small particle size and relatively large surface area of micro- and nanoparticles (MNPs) make them capable of adsorbing other novel entities, leading to the formation of aggregated contamination.
