To limit the effects of climate change, global average temperature since pre-industrial measurements are to be kept well below 2 °C preferably even at 1.5 °C.

The project Deconstructing Stability aims to improve reconstructions of late prehistoric landscapes and predictive models for the purpose of archaeological heritage management.

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…

Prof.dr.ir. Hai-Xiang Lin is appointed on 1 March 2015 as part-time professor on Data Analytics for Environmental Modelling at CML on behalf of the R. Timman foundation. He will join the CML-department of Industrial Ecology. He has a position at the Department of Applied Mathematics at the Faculty…

We use zebrafish as a model organism to study human development and disease as well as animal welfare and environmental impact.

Description of Biotic ligand models: making an inventory of available models & assessment of the variability of the predicted HC5 using the BLMs in different Dutch water types (2005 - 2007)

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

PhD candidates carry out a programme of independent research and additional (limited) course work, culminating in production of a PhD thesis in typically 4 years.

This research programme aims to increase the scientific understanding of how current and emerging anthropogenic threats affect biodiversity and ecosystem services to facilitate strategic management of natural resources. To this end, we address urgent challenges in relation to the mechanisms involved…

Natural resources are becoming increasingly scarce. If we want to maintain our current standard of living, we will need inventive solutions. The researchers at the Institute of Environmental Sciences (CML) share their thoughts on how to achieve a fully circular economy in which as little use as possible…

In the absence of stringent and coordinated international action, States might seek alternatives to promote environmental protection unilaterally.

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.

Evaluating the environmental consequences of diet changes in the European Union.

The objective of this project is the development of a new psychometric model, called the Generalized Squared Distance Logistic Model (GSDLM). This model is an evolution of older psychometric approaches (such as PARELLA, GHCM, and GGUM) and the Gaussian Ordination Models (GOMs) used in environmental…

Can the (industrial) herbal extraction process be mathematically described and can this model be used to optimize the extraction in terms of quality and economical parameters?

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

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).

We strive to address the challenge of constructing a modeling language to write software which can take advantage of recent hardware developments (multicore, cloud) without compromising in its abstraction levels.

The state of our environment is a global concern. Despite an increasing awareness, setting internationally binding and ambitious commitments has proven to be a very difficult process. Can unilateral trade measures form an alternative and contribute to global environmental protection?

What is the best way to combine the environmental and economic data and how can we create an operational system to do so, thereby supporting the delivery of data to the Data centres on Products and Resources?

They were called 'annoying brats', the group of campaigning scientists who in 1978 founded what is now an internationally acclaimed ecological research institute. Their stories and those of the current staff of the Institute of Environmental Sciences are described in the book 'Forty years of Leiden…

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

This computational approach to the complexity of text comprehension is useful for describing the cognitive processes involved.

Existing work in probabilistic language modeling can be mostly divided into two categories:
