At the start of the 20th century there were fewer than 2 billion people. Now at over 7 billion, Earth’s population is on target to reach 8 billion by 2027. How has this dramatic increase in human population impacted Earth’s life support systems and natural resources? How should we understand the meaning…

How do crises produce changes in specific European Union foreign policy areas, and how should we conceptualise these policy changes?

In this paper, Kantorowicz aims to track the persistent effect of former partitioning borders on property tax rates in Poland.

In this article, Marco Cinelli, assistant professor at Leiden University College The Hague, examines proper and improper uses of Multiple Criteria Decision Analysis (MCDA) methods in energy systems analysis.

Understanding how galaxies form, interact, and evolve comes largely from comparing theory predictions with observational data. Numerical simulations of galaxies provide the most accurate approach to testing the theory, as they follow the non-linear evolution of gas and dark matter in great detail and…

Huub de Groot is professor in Biophysical Organic Chemistry. With his team he works in the field of photosynthesis and artificial photosynthesis. The molecular basis for photosynthesis is formed by protein complexes and organelles that contain chlorophyll molecules. The antenna systems herein capture…

Climate change and energy transition were an important theme of the Dutch provincial elections: how should we invest in new sources of energy? Leiden University conducts multidisciplinary research into renewable energy solutions. Read more about this in the ‘Renewable Energy’ research dossier.

Public policy is often the subject-matter of pervasive and deep moral disagreement. Moral disagreement, understood as the difference and opposition between principled moral arguments, can and does occur between policy professionals, different political parties and individuals or groups that compose…

In this thesis, we study different curved single crystals because of the diversity of surface structures across their curvature.

This thesis aims to address offshore wind energy (OWE)-related environmental impacts.

The aim of this research is to understand the linking of crises for the combination of climate change and the COVID-19 pandemic.

European policy affects our lives: from air quality to the frequency of a bus service. Leiden researchers analyse how the European Union functions, how countries apply European policy and whether this policy actually provides solutions and delivers.

After an initial suggestion of a move toward Israel, India’s Prime Minister Modi has signaled a significant recalibration of his government’s engagement with the Middle East region. Now, India seems to be prioritising strong ties with the Gulf states.

In this thesis, classes of strongly interacting quantum field theories, have been studied.

Leiden experts research ways in which European legislation is converted into national legislation. Knowing how this process works can inspire policy-makers trying to achieve their aims while abiding to Europan legislation.

Despite the rapid progress in solar and wind energy, a completely clean energy supply remains a huge challenge. Heavy industry, aviation, shipping and road transport are not yet able to do without carbon-based fuels. To reach the climate goals, in these industries energy consumption should be CO2 neutral. In…

The development of new environmentally sound technologies is seen as a key route towards achieving sustainability.
