This paper critically compares seven widely used risk assessment tools for violent extremism, including the VERA-2R, the ERG 22+, the SQAT, the IR46, the RRAP, the Radar, and the VAF.

Monday 29 January, the annual meeting of Leiden-Delft-Erasmus Centre for Safety and Security (LDE CSS) took place at Wijnhaven. The conference started with pitches of projects financed via seed money of LDE CSS. Followed by interaction in small groups to formulate research and education topics for the…

What performance criteria does a new technology have to fulfill in order to be added to the list of future energy options and what constraints exist in terms of broad market penetration?

This project aims to explore the environmental impact of early Roman expansion (4th/3rd century BC) through a program of dating and ecological sampling of traces of field systems (centuriations).

Principles of Environmental Sciences provides a comprehensive picture of the principles, concepts and methods that are applicable to problems originating from the interaction between the living and non-living environment and mankind. Both the analysis of such problems and the way solutions to environmental…

How to ensure the environmental and economic benefits of circularity transition at macro-scale?

How can prospective LCA be streamlined in a way that its practical application in research and technology development increases?

This research sets out to answer the following questions:

Analytical tools for environmental design and management in a systems perspective. The combined use of analytical tools.

Covering the entire chain of Environmental Risk Assessment

The aim is to develop methods to assess environmental and occupational exposure to (individual) pesticides, to be applied in epidemiological studies investigating pesticide exposure and human health. Furthermore, we aim to investigate the potential association between exposure to pesticides and Parkinson’s…

Freshwater is an important resource, but at a great risk of species decline due to habitat loss, pollution and over-exploitation, and invasive alien species.

Various departments of the university have worked on developing the institution’s environmental policy plan: het Milieubeleidsplan Universiteit Leiden 2016-2020.

CML is an institute of the Faculty of Science of Leiden University.

Review Committees, with cross-boundary experts, are invited to assess our research and education programmes. All our research will be evaluated once every six years, based on the national evaluation system for publicly funded research in the Netherlands.

The project’s overall goal is to improve Indonesia’s environmental legal framework and its implementation by strengthening the regulatory capacity of the government, and by enhancing the capacity of CSOs and scholars to hold the government accountable for its regulatory performance.

What is the environmental impact of different waste collection systems across Europe? How can the collection be improved when considering collection, sorting, and treatment, as well as use options for secondary materials?

In higher education intermediate assessment is used in different ways. In her PhD research Indira Day shows that lecturers should be able to continue to have the freedom to use various test forms, because not one type of test is optimal.
