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.

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.

During the farewell reception on 29 August, the Faculty of Science will say goodbye to Dean Geert de Snoo. On 1 November 2019, he will continue his career as Director of the Netherlands Institute of Ecology (NIOO-KNAW). Colleagues talk about his significance for ecology, about his contribution as a…

This timely and engaging book examines the rise of populism across the globe. Combining insights from linguistics, argumentation theory, rhetoric, legal theory and political theory it offers a fully integrated characterization of the form and content of populist discourse.

Unmanned aerial vehicles (UAVs), often referred to as drones, have become easy and inexpensive to buy, and it is generally expected that the use of drones by private individuals, businesses and public authorities will increase tremendously in the coming years. This raises questions as to what is technologically…

Squatters and autonomous movements have been in the forefront of radical politics in Europe for nearly a half-century—from struggles against urban renewal and gentrification, to large-scale peace and environmental campaigns, to spearheading the antiausterity protests sweeping the continent.

In recent years, the use of primary data in terrorism research has increased. In order to maximise the benefits of this trend, we want to encourage terrorism scholars to implement open science practices more systematically. This article therefore presents different avenues towards open and reproducible…
