Building more in urban areas is, in most places in the Netherlands, the smartest way to tackle the housing crisis. This is evident from research conducted by Janneke van Oorschot, published in a partner journal of Nature. Remarkably, this does not have to come at the expense of green spaces in cities.…

The Municipality of Leiden will work together with Naturalis…

Changes in our climate, the decline in biodiversity, the development of vaccines against new infectious diseases and whether we are the only inhabitants of the universe: these are just a few of the pressing challenges our society faces today. But which scientific choices must be made at the national…

On Monday 14 November, the first spadeful of earth was dug for the construction of the Living Lab, an experimental test site to study living organisms in freshwater. A total of 36 ditches will be dug out to create a natural environment where researchers can study the effects of chemical compounds from…

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.

For present purposes, it is important to distinguish between an early period of settlement, about 6800-6200 BC, and a late period, about 6200-5800 BC, at Tell Sabi Abyad.

The project seeks to come to an understanding of the archaeology of the desert and the ways in which its inhabitants engaged with their constraint, marginal environments through time. It compares and interprets site distribution and community organisation over a long time scale and across several different…

Leiden archaeologists investigate how people in the past impacted their environment. Together with scientists, environmental scientists, and humanities experts, they use this information to draw conclusions about the present – and show what we can learn from it for the future.

If a society is to be secure, sustainable and resilient, conflicting interests must be reconciled. Researchers at Leiden University study the behaviour of individuals, groups and states in relation to this issue, and use their knowledge to promote equality within and between communities.

This research project studies the distribution and impact of medieval malaria in the Netherlands.

The research aims at achieving a European consensus on a harmonized LCA approach/framework to be applied in E-mobility sector. The research will focus on needs and gaps in current LCA practices in E-mobility and try to provide solutions for them based on the rich knowledge and experience represented…

How to contribute to a quantum leap of eco-industrial symbiosis in China?

We are all aware of the importance of a healthy lifestyle. However, at the same time we also experience many difficulties when we are trying to change our behavior to become more healthy. For example, more often than not our good intentions to exercise more or to eat fewer unhealthy snacks fail miserably…

In ancient times, the steppe in the hinterland of Petra (Jordan) was transformed into a green oasis. This project tries to shed insights in the agricultural, water management and societal processes resulting in this transformation. This will be accomplished by practicing an interdisciplinary research…

Over the past century, the world population has grown exponentially, as has our need for energy and raw materials. If we wish to continue to live prosperously in the future, we have to radically restructure our economy and consumption. Scientific research shows us how to do this.
