Dumb island birds, invasive species dressed as cute purple flowers, and trees the size of skyscrapers. What better way to end your summer and start the new academic year than by discussing, scavenging, and observing these topics. This is exactly what the PhD candidates of Young Liveable Planet (YLP)…

The publication of the recent IPCC report on climate change has not gone unnoticed, to put it mildly, certainly not within the Liveable Planet community.

In 2021, Leiden University will develop a new Sustainability Vision 2030. This vision for the future focuses on the primary tasks of the University: integration and visibility of sustainability in our education and research.

With the Liveable Communities – Liveable Planet project, Marja Spierenburg, Professor of Anthropology of Sustainability and Livelihood, is showing that scientists are driven by ambition, hope and faith. She is linking Vrouw Vennepolder, a polder in Zuid-Holland, to the UN climate goals.

At Leiden Observatory, researchers investigate the origin of stars and their planetary systems. They detect and characterize planets around other stars, which are called exo-planets. They study how stars and planets form. And they follow molecules from interstellar clouds to nascent planet systems.…

They study how stars and planets form. And they follow molecules from interstellar clouds to nascent planet systems. This way they address…

Diverse types of exoplanets such as gas giants on close-in orbits (hot Jupiters) and young massive giants on wide orbits (super Jupiters), with no analogs in the Solar System, pose challenges but also opportunities to our understanding of planet formation and evolution.

This thesis addresses the chemical processes that determine the compositions of giant planet atmospheres.

High-angular-resolution observations of the circumstellar material have uncovered numerous and very diverse substructures in protoplanetary discs, raising the question of whether they are caused by forming planets or other mechanisms.

For the first time, international researchers have mapped the network of bacteria on coral reefs. They write about it in Nature Communications (9 April). Professor by special appointment Nicole de Voogd (Naturalis Biodiversity Center & Institute of Environmental Sciences) and two of her PhD students…

From 9 September onwards, Leiden scientists, citizens and farmers will jointly investigate how to sustainably manage peat meadowland. In ten years' time, they hope to have learned how to promote biodiversity and simultaneously reduce nitrogen and CO2 emissions, among other things. The research will…

The role of culture and diverse knowledge systems needs to be recognized when assessing nature’s contributions to people, a new policy forum paper in Science states. Alexander van Oudenhoven and thirty global experts present a new approach that will increase the effectiveness and legitimacy of policies…

Fluctuations in individual plant communities contribute to the stability of an ecosystem as a whole, a study published in Ecology Letters shows. Nadia Soudzilovskaia and colleagues for the first time used data from plant communities across five continents to prove this hypothesis.

The research within the Liveable Planet programme is clustered around four themes. Find out why these topics deserve our attention.

Ecologist Rosaleen March from the Institute of Environmental Sciences (CML) will carry on her research on functional biodiversity: a measure to assign value to ecosystems. Following her previous Marie Curie co-fund, she now receives a full Marie Curie fellowship. March: ‘We need to know how losing biodiversity…

When mosquito eggs hatch in nutrient-rich water, the mosquitoes are larger and they can also fly further. That is the first conclusion of a study from by the Netherlands Centre for One Health (NCOH) by PhD-student Sam Boerlijst.

This thesis discusses the physical and chemical processes than influence the composition of forming planets.

Lecture

In the large gas clouds between the stars, chemical reactions take place under extreme conditions, giving rise to both small molecules, such as water and common salt, as well as large complex molecules that can serve as the building blocks of life. This is known as astrochemistry and it is something…

The Liveable Planet programme will serve as a hub for the wide range of relevant research carried out within Leiden University and welcomes interaction with colleagues interested in contributing to the initiative within as well as outside of Leiden University.

One of the key discoveries in exoplanet research over the past decade is the abundance of small planets in our Milky Way. Despite their high numbers, our understanding of their atmospheres remains limited, and it is unknown if they possess atmospheres at all.

How should we organise interdisciplinary work within Leiden University? This was the key question at a symposium organised by the Liveable Planet interdisciplinary research programme. Radical ideas, like getting rid of the faculties, came up for discussion.

Leiden University has taken eighth place in this year’s SustainaBul, the sustainability ranking for universities and universities of applied sciences in the Netherlands. It was in 18th place last year.

The focus of this thesis is how stars like our Sun and planets like Jupiter, Saturn, and Earth are formed.
