What is the role of local authorities and communities in shaping how inter-Schengen borders are understood and dealt with?

This special issue of Media History (22-3/4, 2016), co-edited with Helmer Helmers (University of Amsterdam), develops a new perspective on the early modern communication revolution. It discusses news as a specific kind of information – by its nature continuous, unreliable, and diffuse – which needed…

What happens to the different waste streams?

The university is making its campuses future-proof with measures for climate adaptation and biodiversity. You can read in the Sustainability Implementation Agenda 2023–2026 how we harvest rainwater, limit heat stress and make more room for greenery.

Whether implicitly or explicitly, we all have ideas about how the law is supposed to function, whose interests it should represent, and what role it should play in society. This project explores the ways in which these questions are addressed in the works of the Roman historian Publius Cornelius Tacitus…

Mattias Brand defended his thesis on 10 April 2019

Bioenergy with carbon capture and storage (BECCS) is a promising method for removing carbon dioxide (CO2) from the atmosphere and simultaneously generating energy. Yet this method is controversial, as it may require a great deal of land and water. Researchers at Leiden University have now proposed a…

Professor Ewine van Dishoeck, together with an international team of colleagues, has written an overview of everything we know about water in interstellar clouds thanks to the Herschel space observatory. The article, published in the journal Astronomy & Astrophysics, summarizes existing knowledge and…

In this book, Sarah Giest, Assistant Professor at the Institute of Public Administration, provides insight into the collaborative and absorptive capacities needed to provide public support to local innovation through cluster organizations.

Pre-modern long-distance trade was fraught with risks which often created conflicts of interest. The ensuing disputes and the ways the actors involved dealt with them belong to the field of conflict management.

On 6 June 2019, Edward Donelan defended his thesis 'Regulatory Management Policies and a Universal Model for Public Policy Making, Legislative Drafting and Managing Stocks of Legislation'. The doctoral research was supervised by Prof. W.J.M. Voermans.

Are predictive archaeological maps a reliable tool to play an important role in the spatial planning? One of the goals of this project was to develop best practices for the production and application of the models.

Ludo Block wrote the eleventh chapter of the book 'Post-Crimea Shift in EU-Russia Relations: From Fostering Interdependence to Managing Vulnerabilities'. His chapter 'Business as Usual? Police Cooperation under a Cloud of Political Animosity' can be found on page 204 of the book.

This project investigates how early print media covered distant but urgent geopolitical conflicts, using newspapers from the Low Countries, north and south.

When mosquito eggs hatch in nutrient-rich water, the mosquitoes are larger and they can also fly further. That is the first conclusion of a study from by the Netherlands Centre for One Health (NCOH) by PhD-student Sam Boerlijst.

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…

On 26 and 27 September 2024, Leiden University's Grotius Centre for International Legal Studies hosted the H2OLAW conference entitled 'Law-science interfaces within the law of the sea and fresh water law’. The conference marked the launch of a multi-year research project led by Dr Hilde Woker and Dr…

Professor of Ecotoxicology Martina Vijver and lecturer Maarten Schrama are the founders and managers of the Living Lab. As well as these two researchers, a number of other ecologists and biologists are involved in the research at the Lab.

Majuka Tanabe defended her thesis on 17 June 2015

The world is full of wars, and no war is without its dead. What happens to the bodies of fatal casualties of armed conflict? The winner of the faculty Jongbloed Thesis Prize 2015 is Welmoet Wels (Public International Law). Her thesis Dead body management in armed conflict: paradoxes in trying to do…

A leak developed in the mains water supply in the new building of Leiden University’s Faculty of Science at the Wassenaarseweg on Tuesday evening.

Research truly comes to life when it contributes meaningfully to society. By sharing our findings, advising policymakers or contributing to community projects – we can make a real impact. Scroll down and discover how Science and society can mutually benefit from each other.

At Leiden Observatory, researchers investigate the origin of stars and their planetary systems. They detect and characterize planets around other stars, which are called exo-planets. They study how stars and planets form. And they follow molecules from interstellar clouds to nascent planet systems.…

Curious about how sustainability fits into our university's strategic plan, or how much energy and water we consume? Read about it here.

Leiden University purchases a wide range of goods and services every year. To a greater or lesser extent, they all have an environmental impact.

RAWCLIC’s main goal is to develop knowledge on the future raw materials (RMs) demand, supply and associated environmental impacts induced by the energy and digital transitions in the EU, and to support fact-based industry- and policy- decision-making enabling these transitions.

In this project we ask: how does pollution manifest as part of different practices, both socially and materially.

This project investigates the capacities of EU institutions to coordinate the responses of member states to critical events.

Leiden archaeologists investigate how people in the past impacted their environment. Together with scientists, environmental scientists, and humanities experts, they use this information to draw conclusions about the present – and show what we can learn from it for the future.

To what extent are there differences between countries in and outside the European Union and the Schengen area in the level of crimmigration, the merger between migration control and crime control, and to what extent can these differences be explained by the way in which state and non-state actors in…
