Rich countries are getting richer because of environmentally polluting (construction) investments from the past, largely at the expense of poor countries. This was shown by long-term economic and environmental data. 'The gap between poor and rich countries is widening.' Scientists from the Leiden Institute…

Development of an aggregated impact indicator to measure decoupling.

The earth has more than 7 billion inhabitants, all of whom leave behind traces of pollution. However, not all forms of pollution have the same harmful effect. Leiden scientists help determine where we should put our priorities.

What are the environmental trade-offs for SMEs considering moving from monoculture aquaculture practice towards IMTA? What are the environmental trade-offs comparing IMTA species with their conventional monoculture alternatives?

CML’s education programme aims at training (under)graduate and graduate students for integrated and multidisciplinary sustainability research and for better decision making in managing the world’s natural resources, environmental quality and biodiversity.

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,…

EXIOBASE is a global, detailed Multi-regional Environmentally Extended Supply and Use / Input Output (MR EE SUT/IOT) database. It was developed by harmonizing and detailing SUT for a large number of countries, estimating emissions and resource extractions by industry, linking the country EE SUT via…

Our institute aspires to be the center of excellence for strategic and quantitative research and education on sustainable use and governance of natural resources and biodiversity. We have two distinct research programmes: Environmental Biology and Industrial Ecology. The department of Industrial…

The currently available in vitro generated human skin equivalents resemble the human skin in many aspects. However, some essential barrier characteristics do not fully mimic the native barrier. Consequently, the human skin equivalents cannot be used for screening of drugs for skin penetration.

Bacteria often experience external challenges, such as changes in environmental conditions or attacks by bacteriophages.

This dissertation presents a legal geographical analysis of the heritage laws of the independent English-speaking islands of the Lesser Antilles.

A new environmental accounting framework using externality data and input-output tools for policy analysis.

The Institute of Environmental Sciences has carried out and participates in several projects that deal with the analysis of energy systems.

This doctoral trajectory explores sound, its image and its role in relating humans and our technologies to the environment.

The map application includes information from old and new buildings archaeological projects. This makes it possible to investigate whether water facilities (wells, cisterns) and waste facilities (cesspits, sewers) were the privilege of Leiden’s wealthy elite in the late 16th and 17th centuries or whether…

At the Faculty of Archaeology, we investigate the development of human societies worldwide, from the earliest beginnings to modern times. We also study the heritage of mankind, which evokes this deep history, and which connects with, and informs, contemporary society.

On 11 February 2022, the Urban Governance Research Network (Ugovern) organised a webinar ‘Understanding Recent Changes in Belgium and the Netherlands Planning Law’. Rogier Kegge was one of the panel members during the webinar.

On Friday morning, 8 June, Thijs Bosker, Associate Professor at Leiden University College, was interviewed by NPO Radio 1 on plastic pollution in Antartctica: ''Anually, an additional 4 - 12 billion kilos of plastic ends up in our ocean''.

When oil is harvested from the seeds of the oil palm tree, the fruit residue can be used to make bio-ethanol. However, it can also be used as a fertilizer on palm tree plantations; which option is best for the environment? Edi Wiloso compared the two green options at the Institute of Environmental Sciences…

Urban, Food, Water, Biodiversity, Resources and Energy: these are the main research topics of the Institute of Environmental Sciences. We always strive to be a global leader in our field. And make a real impact with both our research programmes.

On Friday evening 8 June, Thijs Bosker, Associate Professor at Leiden University College (LUC), was on television in NOS Jeugdjournaal about plastic pollution and microplastics

Rogier Kegge, Assistant Professor at the Institute of Public Law of Leiden University, was interviewed by Dutch newspaper de Volkskrant in response to the recent recommendations by Johan Remkes on how to approach the nitrogen crisis.

This 3-year EU Erasmus+ co-funded project focuses on the strengthening and improvement of teaching qualitative research methods across a range of disciplines in the Social Sciences and Humanities in Bhutan.

Which metabolites of sponge are influenced by individual environmental or biological factors?

Within the Centre we cover several research themes.

We investigate water quality and want to understand the effects of human interference on aquatic biodiversity.

This project combines an extensive new open database on linguistic distributions, spatial modelling and areal linguistics in order to disentangle the roles of social and environmental factors on the emergence of linguistic diversity patterns of South America.

Four students of the MSc Industrial Ecology have recently been selected to participate in the accelerator programme of the EIT Climate-KIC, which helps sustainable start-ups. The four students use coconut husks to develop sustainable boards, which can be used to make furniture.

Dutch provinces must finalise their plans this summer to meet the government's targets on nitrogen emissions. Can the outcome of the provincial elections this week still change nitrogen policy? The NOS spoke about this issue with various parties including Rogier Kegge, assistant professor in administrative…

Examining the sustainability aspects of biotechnology, especially those related to the production of ethanol from biomass.

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,…

The car we buy is made out of thousands of components, which are produced using different types of materials. These materials need to be sourced from different places, sent to production facilities and assembled. Once the car is dismissed, the components need to be taken care of by either reusing, recycling…

We aim to develop a microfluidic platform that can parallelize testing the performance and characteristics of pure, mixed and environmental bacteriophage samples.

The planetary boundaries concept defines the environmental limits within which humanity can safely operate, that is, the Earth System processes that set safe boundaries for human activities.

RaMa-Scene is a web-application to create and analyse circular economy scenarios using Multi-regional Environmentally Extendend Input-Output Analysis.

The EEE lectures are a monthly cross-disciplinary lecture series where globally renowned and inspiring thinkers and scientists are invited.

A sustainable resource management is an essential aspect to satisfy the current human needs without compromising the needs of future generations.

Material outflows from industrial economies.

Engineered nanomaterials (ENMs) are widely used, and nanotechnological innovations grow with rapid pace. Studies on nanotoxicology have demonstrated that chemical toxicology as well as particle toxicology should be accounted for in predicting the safety of ENMs.

The main question I want to answer is about the mutual influence between the cultural and settlements changes that occurred between the Bronze and the Early Iron Age in Margiana and the management of water resources.
