Food security is challenged by a growing global population and by climate change. Drought and soil salinity are considered the most important ones that inhibit crop yield and distribution. Worryingly, climate change is predicted to increase not only their frequency and severity, but also their co-occurrence,…

The application of nanomaterials in industrial processes and consumer products provides many societal benefits, but can also lead to the release of nanomaterials into the environment. The work in this dissertation aims to provide insights into the potential environmental impacts that may follow from…

Freshwater biodiversity has been threatened by eutrophication due to excessive nutrients in the environment. Releasing the freshwater species from such pressures requires efforts from industry and manufacturers to avoid emissions to vulnerable and high-risk regions.

Both on a personal and institutional level, the staff of Leiden CADS collaborates with:

Indonesia is experiencing various environmental challenges related to its fast economic growth. Therefore, it is necessary to have measurable and applicable indicators to obtain accurate data and information regarding the costs of adverse environmental impacts arising from economic activities to support…

The thesis describes terrestrial field trials aimed to detect side-effects of pesticides within the framework of pesticide registration procedures. Field trials were developed using vascular plants Brassica napus and Poa annua, caterpillars Pieris brassicae and effects on decomposition were studied…

This thesis examines the impacts and challenges of water use of electric power system. This thesis found that there are large differences in water use of electricity technologies, with hydropower and thermal power being two large water users.

Biodiversity enables ecosystems to thrive through the synergy of functional differences among organisms. While human well-being strongly depends on biodiversity-driven ecosystem services, human actions are also at the root of current unprecedented biodiversity declines.

A circular economy in which all resources are reused is a prerequisite for a sustainable world. As EU president, the Netherlands can give a firm impetus to this economic shift. This is the message of Leiden Professor of Industrial Ecology, Arnold Tukker, in his inaugural lecture on 26 February.

It is fifteen years since the first issue of The Hague Journal of Diplomacy (HJD) in 2006. To mark the occasion, we put together an editorial on where diplomacy, diplomatic studies and HJD might be going.

The Institute for Advanced Study has appointed astronomer and chemist Ewine Fleur van Dishoeck to its Board of Trustees, effective 5 May, 2018.

Two Leiden students stand a chance of winning the ECHO Award for Higher Education. Deniz Rana Kuseyri (Rana for short) and Ruşen Koç are two of the six finalists for this annual national prize that is awarded to students who promote diversity and inclusion in their own discipline.

It’s starting to become a real Dies Natalis tradition: on 8 February professors from Leiden University teach a class at primary schools in the region. This introduces children to academia and teaches them more about conducting research. ‘Had you expected me to be a woman?’

Covid year 2021 might have felt somewhat less strange than the year before, but the virus still left its mark on University life and our students and staff. Fortunately there was also room for research, visiting dignitaries and in-person classes. And our social media accounts weren’t only about covid…

Universiteit Leiden en Unicef werken al 10 jaar samen om kennis over kinderrechten uit te breiden en te verspreiden. Ze verlengen deze samenwerking.

Leiden University consists of seven faculties, each managed by a dean.

Leiden University is awarding an honorary doctorate to virologist Marc van Ranst. Van Ranst has been one of the main advisers of the Belgian government during the Covid pandemic. German Arabist Beatrice Gründler will also receive an honorary doctorate for her work in the field of Oriental Manuscript…

The energy transition ranks high on the European policy agenda, but what does it take to get there? René Kleijn researches how we can extract, use and reuse raw materials in a responsible way. Since 1 March, he has been appointed professor of Resilient resource supply.

The Municipality of The Hague called on researchers to come up with a proposal for an innovative research project on problems big cities face such as energy transition. Four of the five projects that have been granted funding come from researchers from Leiden University.

Video conferencing from your sitting room and algorithms on social media that know your interests: new technology is an increasingly integral part of our lives. At the same time there is a growing call to protect our privacy, and this is causing friction, at the University too. In part because of the…

Urbanization brings benefits like housing and jobs but also challenges like biodiversity loss. CML's Urban research program uses science to create sustainable cities, focusing on the built environment (circular economy, urban mining) and enhancing urban nature for biodiversity and human benefits.

What is the size and composition of the Dutch urban mine? How will the urban mine develop over time, and how can it be used as a source of materials as part of a circular economy?

The Faculty of Science is located at the Leiden Bio Science Park. It was founded more than two centuries ago and currently, more than 8000 people are working and studying at the eight institutes.
