As a virtually inexhaustible source, solar energy plays a major role in future global energy scenarios.

In the search for sustainable energy solutions, the idea of artificial photosynthesis has been proposed as an approach with which to use water and sunlight to produce hydrogen.

This project focuses on a striking parallelism between two macro-groups of languages: southern Italian dialects and the so-called split-ergative languages, like Basque, Georgian, Dyirbal, Hindi/Urdu.

How do societies move forward with sustainable, effective and efficient management of Earth's water resources?

This thesis deals with properties of Jacobians of genus two curves that cover elliptic curves.

We need drinking water for making tea and coffee, but not for flushing the toilet. By reducing the consumption of clean water, Leiden University is helping to minimise the environmental impact.

The International Course on Water Use and Management in Cagayan Valley The Philippines (2011-2015)

Human activity, such as pollution, may disturb the balance of living water systems, which has consequences for biodiversity, but also for other functions such as water purification. Leiden University maps living water systems using the most advanced technologies.

This project investigates ancient water management of streams, springs and runoffs on the archaeological site of Monte Albán, Mexico, as a means to contribute with different stakeholders in the development of sustainable solutions to water problems today such as floods and scarcity.

Astronomical observations of cold regions in the universe show a rich inventory of ices. Part of these ices may end up on planets like our own, but in that journey they will be exposed to considerable amounts of radiation.

Improving environmental risk assessment of pesticides in surface waters

PhD Defence

While ecosystems have concrete benefits for human society, these benefits are typically overlooked in decision-making.

Before the large scale use of renewable energy sources can be implemented in our society, the storage of electrical energy needs to be tackled. Storage the energy as hydrogen via the reduction of protons is a good option.

In this dissertation, the synthesis and characterization of a series of iron complexes based on different ligand platforms are described.

Understanding the water use of power production is an important step to both a sustainable energy transition and an improved understanding of water conservation measures. However, there are large differences across the literature that currently present barriers to decision making.

In this dissertation iron-based homogeneous catalysts were synthesized, characterized and investigated for water oxidation activity.

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.

“A partnership based on water” summarised Gerhard van den Top the relationship between the Netherlands and the Philippines in the 4th Louwes Lecture. He emphasised the significant role of international and intercultural cooperation in managing the complex challenges brought forward by climate change.…

Archaeologist Araceli Rojas has been invited to participate in the award-winning festival Let’s Talk about Water. This festival combines academic seminars, movies, and panel discussions around water issues around the globe.

Twenty years from now, the world population is estimated to be around 8.7 billion people, compared to the current 7.3 billion. In combination with the improvements in living standards and the corresponding growth in consumption, this will result in an enormous increase in the demand for food, consumables,…

Leiden astronomers and ecologists are developing an instrument that lets people measure the quality of surface water with a smartphone.This international citizen science project, MONOCLE, is a collaboration between scientists and local people in Tanzania, Brazil and four European countries.

Using a clever experiment, PhD candidate Shengxiang Yang discovered how gold electrodes convert water into oxygen. He is the first to unravel the mechanism of this reaction. Yang published his results in the journal ACS Catalysis.
