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

Leiden University is committed to reducing our water consumption.

We investigate water quality and want to understand the effects of human interference on aquatic biodiversity.

On 27 January 2022 Tjahjono Prasodjo successfully defended a doctoral thesis and graduated.

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.

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.

Water is all around us and is vital for all aspects of life. Studying the various compounds and life forms that inhabit natural waters lets us better understand the world around us.

Improving environmental risk assessment of pesticides in surface waters

This thesis examines the impacts and challenges of water use of electric power system. This thesis found that there are large differences in water use of electricity technologies, with hydropower and thermal power being two large water users.

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.

To design the ideal water oxidation catalyst, understanding of the catalytic mechanism and decomposition pathways is essential.

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

AI:Liner develops cutting-edge digital solutions for sewer asset management while ensuring responsible AI adoption through comprehensive social science research and ethical frameworks.

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.

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.

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.

It may not seem necessary to install special tap water stations in University buildings, but it is very useful: every tap here also means a tap in a developing country. With the the 35 tap water stations that Leiden University installs, the slum area of Madoya in Nairobi will soon have clean drinking…

Amerindian intra- and inter-insular relationships and social organization in the pre-colonial Windward Islands.

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

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

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.

Climate change is one of the largest challenges faced by humanity. To combat this research into alternatives to fossil fuels is ongoing. Dihydrogen is considered a good alternative fuel, since its burning only forms water.

Consequences for sediment stability and seston trapping

We report new computational and experimental evidence of an efficient and astrochemically relevant formation route to formaldehyde (H2CO). This simplest carbonylic compound is central to the formation of complex organics in cold interstellar clouds and is generally regarded to be formed by the hydrogenation…

Professor Ewine van Dishoeck, together with an international team of colleagues, has written an overview of everything we know about water in interstellar clouds thanks to the Herschel space observatory. The article, published in the journal Astronomy & Astrophysics, summarizes existing knowledge and…

Ice, the solid state of water, plays an important role on our planet as well as the entire universe.Despite the fact that an individual water molecule has a very simple structure, its chemical bonding in the solid phase can be surprisingly complex.

Publication on the excavations at Roman fort Matilo in Leiden

Training a robot in a real-life environment is more or less impossible. Computer scientist and psychologist Roy de Kleijn switched to training in a simulated, virtual one instead. ‘You do have a reality gap, but the more precisely you train the robot, the better it is in practice.’ His inspiration:…

In order to analyze the challenges linked to data use in the context of nexus governance, Giest & Mukherjee use a policy design lens and more specifically the perspective of organizational policy instruments to look at the Mediterranean region.
