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

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

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.

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.

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

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.

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

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.

Improving environmental risk assessment of pesticides in surface waters

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.

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

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.

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

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.

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.

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

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

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

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.

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.

CML report 192

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…

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.

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.

Dr. Tommy van Steen, Universitair Docent in Cyber Security Governance bij het Institute of Security and Global Affairs, werd geïnterviewd door mediaplanet over internetcriminaliteit en hoe wij deze dagelijks kunnen tegenkomen via onze computers en telefoons.

On 29 april 2020, Beth Van Schaack defended her thesis 'Imagining Justice for Syria: Water Always Finds Its Way'. The doctoral research was supervised by Prof. C. Stahn.
