A study of the International Union for Conservation of Nature has identified tree species native to Indonesia’s Kutai National Park that are resilient to climate change. The species support threatened East Bornean orang-utan populations; therefore, the study recommends their use in reforestation efforts.…

This study examines recovery planning committees across Japan's Tohoku region.

In this dissertation the author digs into the constituent elements of River Plate tango in order to decode how specific musical materials were organized and combined by four outstanding musicians: Pugliese, Salgán, Piazzolla and Beytelmann.

Up to 50% of all children and adolescents growing up worldwide are exposed to at least one form of childhood adversity (CA), which is one of the strongest predictors for later-life psychopathology.

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.

What motivated past human societies to repeatedly invest labour, generation after generation, in constructing, maintaining, and enhancing monumental structures in an environment prone to frequent and unpredictable natural disasters? Moreover, how did societal resilience and periods of heightened or…

Agricultural production is one of the most vulnerable sectors to climate change around the world, and poorer countries face significantly more difficulties than the developed world. Coffee is an agricultural commodity that most people enjoy but are oblivious to the climate-related challenges affecting…

The aromatic infrared bands (AIBs) seen throughout the interstellar medium (ISM) are generally thought to be carried by polycyclic aromatic hydrocarbons (PAHs) and their nitrogen analogues (PANHs).

The Persian Empire (539-330 BCE) was the first world empire in history. At its height, it united a territory stretching from present-day India to Libya - and it would take 2,000 years before significantly larger empires emerged in early modern Eurasia. This territorial sweep is both a source of fascination…

In this project, we will study the genetic and environmental drivers of woodiness and stem lignification at the level of plant‐to‐gene‐to‐molecule.

In their quest for materials that conduct electricity without resistance at moderate temperatures, scientists usually work on their chemical make-up. Now Leiden physicists have come up with a radically new approach: pinching holes in a periodic pattern. Publication in SciPost.

Leiden University is an international, broad-based university. We distinguish five core domains for our research and teaching activities.

Our world may seem unpredictable and uncertain, especially when others are involved. When interacting with others, we cannot know for sure what they may be thinking or planning to do, but we do a good job guessing. This may not be so easy for everyone…

The aim of the RAISE study is to investigate how resilient people respond to stress. Specifically, we will study how key biological systems (HPA-axis, immune system) interact with the brain and social environment in order to facilitate resilient functioning after childhood adversities.

How has landscape and land use changed in these two case studies since independence? What has caused these changes, whether anthropogenic or natural? How do local communities in the areas of study perceive these changes? How can community knowledge be integrated with mapping tools (GIS) to contribute…

Positive emotions are important for our health and sense of well-being - they make our lives meaningful. Now, Henk van Steenbergen and his colleagues have published an authoritative new volume on the latest scientific research on positive emotions.

BrainTrain connects scientists with young people. We achieve this by offering a platform where scientists learn from the experiences of young people, and where young people can discover all about their own (brain) development. We organize youth panels and create short podcasts in which both scientists…

In their recent blog, Marieke Liem and Jolien van Breen reflect on the representation of immigrants amongst homicide victims - is there evidence that people from immigrant groups are over-represented amongst homicide victims? And if so, can we discover the reasons why? Find out more through the link…

Professor of Law and Society Maartje van der Woude is searching for innovative ways to facilitate dialogue about topics that are usually experienced as ‘difficult to talk about’ – such as racism, ethnic profiling, exclusion, crimmigration – with a wide audience.

Within the broader scope of the interdisciplinary programme 'Social Resilience and Security', we seek to provide a broad and deep understanding of the dimensions and etiology of transgressive behaviours, the effects of interventions, and resilience against such behaviours.

In light of climate change, it is crucial to determine whether plant species can adapt to future climates to avoid extinction. Plants adapt to various conditions by altering their functional traits, such as leaf size or photosynthetic rate. Some traits appear linked and vary together between species,…

One of the effects of climate change is the phenomenon of desertification, a process that occurs in semi-arid and arid areas and causes land degradation as well as vegetation loss. Due to the lack of resources, vegetation self-organizes to sustain itself by forming large-scale spatial patterns.

Every year Leiden University celebrates the lifting of the siege of 1574, with the 3 October University. This year the event will be held on the 4th of October between 11 am and 1 pm. Visit the tent in the city centre of Leiden, to hear three of our scientists talk about their research on the theme…

Recent figures from Statistics Netherlands show that the total number of homicides has decreased in 2020. But the number of homicides among young people increased. Many have interpreted this to mean that homicide among teenagers in increasing. Marieke Liem, Professor of Social Resilience and Security,…

The Leiden Institute of Education and Child Studies aims to conduct high-quality research that addresses major social issues. This inspires its BSc, MSc and PhD programmes.

Our research examines mental health risk and resilience in young people. We do so by integrating cultural, social, cognitive and neurobiological factors and their interactions.
