The book ‘Pesticides and the Environment’ gives a transparent overview of facts and figures concerning pesticide use in the Netherlands and the impact of pesticides on the environment.

Over time, the temperature in all buildings will be regulated in a sustainable manner. In this way, using gas will not be necessary anymore.

The Grachtwacht (Canal Watch) conducts research on urban wildlife and the impact of plastic on nature. With our clean-ups, we not only collect waste, but also data. This way we try to find out the source of the waste and turn off the tap on shore. This way there is structurally less plastic in the c…

Graphene nanoribbons (GNRs) are used as a current carrying substrate in investigation of current-induced forces in a low-temperature STM (chapter 2).

Atoms and molecules are the basic units of matter. If we keep dividing a bar of gold or a glass of water into smaller parts, at the end we are left with a single gold atom or a water molecule.

Natural resources often stretch across borders that separate modern nation states. This can create conflict and limit opportunities for regulated consumption of their goods and services, but also provide opportunities for joint multinational efforts that exceed single country capabilities.

Supramolecular polymers are class of materials that are formed by non-covalent interactions such as hydrogen bonding, π-π interactions, electrostatic interactions and the hydrophobic effect.

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…

Engineering an efficient microbial enzymatic polyethylene degradation pathway via an innovative combination of biochemistry and computational biology tools for enzyme discovery and characterization.

Globalsmog Seminar Series #7 Morocco

Urbanisation is steadily increasing with estimates expecting that 68% of the global population will live in cities by 2050. To accommodate the rural to urban transition, large quantities of land are transformed from natural to urban lands.

This project aims to answer the following questions: how did the landscape and geography of the local surroundings of Chalcis impact medieval to early modern productivity, habitation, mobility and interaction in a wider sense? And where are such changes and continuations still visible in the landsca…

How has landscape and land use changed in these two case studies since independence? What has caused these changes, whether anthropogenic or natural? How do local communities in the areas of study perceive these changes? How can community knowledge be integrated with mapping tools (GIS) to contribute…

The Urban Studies bachelor’s programme is based on two learning trajectories. One is dedicated to knowledge related to urban issues, while the other focuses on a wide range of practical and academic skills.

On 4 July, Jorrit Rijpma participated in a roundtable event hosted by the European Policy Centre (EPC) in Brussels.

On 17 September 2018 Rijpma, Associate Professor of European Law at the Europa Institute, spoke at the European Academy for European Law’s annual conference on EU border management.

Almost 100 billion tons of CO₂ could be pulled out of the atmosphere by the end of the century. That is, if high-income countries switch to a plant-based diet. The double carbon profit of returning farmland to its natural state would equal about 14 years’ worth of agricultural emissions, researchers…

Social aspects of the learning environment, also called classroom climate, are important for students’ cognitive and affective learning outcomes. In this thesis the classroom climate is operationalised by means of two components: the teacher-class relationship and classroom discipline.

In this article Jeroen Wolbers and Sanneke Kuipers take a closer look at disaster preparedness to reinvigorate the academic debate.

Wout Broekema highlights how organisations not only learn from crises but also forget, losing crucial knowledge and practices over time.

How do authorities and citizens construct meaning in the aftermath of jihadist terrorist attacks through the use of frames, rituals, and symbols. What does this reveal about the communicative impact of terrorism?

The directorate of the Netherlands Research School for Astronomy (NOVA) has two new members. Ronald Stark (currently at NWO) will be the new Executive Director of NOVA from 1 September. Amina Helmi (Professor of Dynamics, structure and formation of the Milky Way at the University of Groningen) will…

On 20 June 2025, Melanie Fink presented her research on ‘Robo Swarms and Polygraphs: The Future of European Border Management and its Human Costs’ at the Research Workshop on ‘Migration law at the intersection of international, EU and domestic law: institutional structures and the protection of human…

For the first time, Leiden University has made it to the top 10 of the UI Green Metric, a global sustainability ranking for universities. Of the 780 participating universities, Leiden has taken seventh place.

Huub de Groot is professor in Biophysical Organic Chemistry. With his team he works in the field of photosynthesis and artificial photosynthesis. The molecular basis for photosynthesis is formed by protein complexes and organelles that contain chlorophyll molecules. The antenna systems herein capture…

This project is funded by the Dutch Cancer Society. The project will be part of an ongoing research line aimed at identifying mechanisms of cancer therapy resistance and metastasis. In this project, it will be investigated how the Grainyhead family of transcription factors controls therapy response…

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…

On 5 October, mediator Johan Remkes presented his report on the nitrogen crisis and what he thinks is the best way forward. Leiden University professor and nitrogen expert Jan Willem Erisman responds to Remkes’s recommendations. ‘It’s a step in the right direction.’

In 2021 many of our students and staff won fantastic prizes and were awarded important research grants. This is our traditional review of these successes as the end of one year marks the beginning of another.

This study examines how European state administrations responded to transboundary crises over the past 30 years and the extent of their successful adaptation.

The aim of this research is to understand the linking of crises for the combination of climate change and the COVID-19 pandemic.

While bioinformatics methods deal with the analysis of sequence information (be it proteins or DNA), the field of cheminformatics is concerned with the analysis of small-molecule datasets.

Multicopper oxidase, laccase, can efficiently reduce oxygen to water and are mostly used in the enzymatic biofuel cells.

In surface science there is great effort to move from studying simple, flat model surfaces in vacuum to investigating more complex model catalysts in gas environments (in situ). This thesis gives three examples of such studies using microscopy and spectroscopy.

This thesis takes steps toward understanding the interaction between gas-phase and solid-state molecules in star- and planet-forming regions.

This research aims to investigate how different social forces interact with hydropolitics in the Eastern Nile Basin and what are the constraints of engagement.
