Unfolding potential

In the last two decades, there have been heated public and scholarly debates in France, the United Kingdom, and the Netherlands on the violent end of empire. Nevertheless, the broader comparative investigations into colonial counterinsurgency tend to leave atrocities such as torture, execution, and…

This article examines Russia’s use of low-level agents in covert operations across Europe since 2022, analysing a dataset of 145 cases to identify patterns in recruitment, demographics and network structure using social network analysis.

We are very honoured to announce that on the 1st July Bart Custers has been appointed Professor of Law and Data Science and has thus become the first Professor in the new 'stimuleringsprogramma' SAILS.

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

Research carried out at Leiden University contributes to our knowledge of sustainability. This is essential if we want to work together to find solutions to pressing issues, such as the current climate emergency and the shortage of raw materials.

How might we include circularity into the models often used in IPCC reporting (in technical language, how can IAMs, dMFA models and CGE models be integrated?) What are possible futures for global resource use and what are the consequences for greenhouse gas emissions in these scenarios?

How can the Safe and Sustainable by Design (SSbD) framework developed in the SSbD4CheM project facilitate the creation of safer and more sustainable chemicals and materials across various industries?

Which consumer groups post the greatest cost to public health and the planet through their food choices, and how can we use this fine-scale information to accelerate a sustainable dietary transition?

How can we improve quality of life and study success in young, high-functioning adults with autism?

Leiden University regularly confers honorary doctorates, and presents awards and prizes.

A lecturer winning a prize, an expert appearing in the media or a professor giving their inaugural speech: these are faces we often see. But we rarely see the staff who work behind the scenes to make their work possible. They are now featured in the photo exhibition ‘The forces behind the faces’.

Leiden Mayor Peter Heijkoop visited the Faculty of Social and Behavioural Sciences and the Faculty of Science on Monday,

During a meeting at the University on 10 November, staff spontaneously removed a painting by artist Rein Dool from the wall in one of the meeting rooms in the Academy Building, reversed it and placed it on the floor. A tongue-in-cheek action with a serious undertone. This has led to a lot of commotion…

The valedictory lecture of former rector magnificus Hester Bijl was buried on Tuesday 12 May in the garden of the Kamerlingh Onnes Building (KOG). Where did this young, and slightly eccentric, university tradition come from?

The Executive Board and the Board of Education of the Institute of Psychology are responsible for the organisation. A number of committees offer specialised knowlegde, such as the Research Ethics Committee. Students have a say in programme committees.

The conflict between Israel and Hamas has had a clear impact on Leiden University. Students and staff are angry or scared, feel unsafe and are experiencing group pressure.

Food waste is a defining inefficiency of the modern food system, with profound implications for resource use, climate change, and circular economy transitions. This dissertation examines food waste through two complementary lenses: the prevention of avoidable food waste and the valorization of unavoidable…

Plastics have become an integral part of modern society due to their versatility and durability.

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?

The research programme Industrial Ecology aims to support the ecological transformation of society and environment towards sustainability. The research subject is Industrial Ecology in its broadest definition, covering environmental systems analysis, and incorporating the social and economic aspects…

Large carnivore population is globally declining as a result of the fragmentation of habitat, large prey depletion and retaliatory killing by pastoralists.

Large carnivores and humans, along with their livestock, have co-existed for thousands of years. However, human population growth and an increase in economic activities are modifying the landscape for large carnivores and their prey.

Animal diet studies are critical for understanding ecological processes such as trophic interactions, energy flow, and nutrient cycling. By examining what animals consume, ecologists gain insights into species specialization, predator-prey relationships, and ecosystem management.

LCA has become an important method to study environmental impacts of human activities. Still, there are several methodological issues in LCA that can adversely affect the results reliability.

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.

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.

The SCS courses train you in practical and theoretical aspects of science communications. Internships help you decide whether you want to choose a career in science communication or Biology research.

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…

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.

To meet the rising demand for minerals driven by the global shift to clean energy technologies, ensuring responsible and resilient supply chains is critical. Minerals like cobalt, lithium, and nickel for batteries, neodymium and zinc for wind turbines, and indium for solar panels are essential.

Material circularity and energy efficiency are highly relevant and intertwined issues for the transition towards a carbon-neutral and circular built environment. In the Netherlands, the building sector has been rendered a priority towards a circular and low-carbon society.

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

This thesis addresses the challenge of sustainable urban development by analyzing the interplay between green and grey infrastructure to optimize resource use and ecosystem services.

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…
