The research within the Food research programme at CML focuses on a transition towards sustainable food production and consumption systems. We investigate from a very small to a very large scale, at a local, national or international level. We do so by researching for example molecular tools, food systems,…

This interdisciplinary minor addresses sustainability challenges from a systems perspective, and investigates ways to sustain society within planetary boundaries.

How can we deal with today’s global challenges in sustainable, peaceful, fair, democratic, and effective ways? How can global events such as geopolitical shifts, ecological changes, technological innovations, and pandemics be better governed? Addressing these complex questions requires innovative, multidisciplinary…

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.

The programme provides you for a succesful career. As a graduate, you will be qualified for positions within organisations such as international courts.

We offer a unique master’s programme because it places equal importance on environmental sustainability and governance perspectives. All core courses are co-developed and co-taught by staff from two different faculties. Combined with the extensive skillset and the explicit focus on inter- and transdisciplinarity,…

Together, they will investigate over a longer period of time which agricultural management leads to the best restoration of biodiversity. The research will start…

How do societies move forward with sustainable, effective and efficient management of Earth's water resources?

Restoring a natural plant environment on exhausted agricultural lands and in nature areas is difficult. We can speed this up by steering the soils towards the desired situation. This is what Martijn Bezemer, newly appointed Professor of Ecology of Plant-Microbe-Insect interactions at Leiden University’s…

It is mostly rainfall and soil acidity that determine which microbes survive in a particular habitat and which do not. This knowledge is important for maintaining biodiversity. Leiden environmentalists contributed to the research. Publication in Nature on 1 August.

Dumb island birds, invasive species dressed as cute purple flowers, and trees the size of skyscrapers. What better way to end your summer and start the new academic year than by discussing, scavenging, and observing these topics. This is exactly what the PhD candidates of Young Liveable Planet (YLP)…
