This Festschrift in honour of Cary J. Martin

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.

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.

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

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.

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

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.

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.

How does the vision of problems and solutions from

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.

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.

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.

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.

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.

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.

Climate Proofing the Neighbourhood: Evaluating Citizen’s Participation in the City of Leiden

Climate Proofing Industrial Estates: Entrepreneurs’s Participation in the City of Leiden

The Dutch atlas with pesticides concentrations in surface waters have been overhauled. This new, free accessible, website is in line with the European Framework Directive on Water (In Dutch: KRW).

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…

Consequences for sediment stability and seston trapping

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.

Indonesia is experiencing various environmental challenges related to its fast economic growth. Therefore, it is necessary to have measurable and applicable indicators to obtain accurate data and information regarding the costs of adverse environmental impacts arising from economic activities to support…

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:…

The last decades it is increasingly recognized that acute as well as chronic postoperative pain is an important problem. Treatment and prevention of postoperative pain is a challenge, especially in special patient populations where there is only limited guidance on how to optimally use opioids.
