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.

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.

The Dutch legal system perhaps appears at first sight not to be very suited for strategic litigation by interest groups. But judgments such as SyRI and Urgenda show that when an interest group does fulfil all the conditions, anything can happen in court.

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.

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.

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.

Interest group Animal Rights has started a test case to prompt the Netherlands Food and Consumer Product Safety Authority (NVWA) to tackle farmers who do not adequately protect their livestock against wolves. The test case concerns a rejected enforcement request to the NVWA. In it, the NVWA were called…

In the Netherlands, anyone who loses their passport or ID card too often can be added to the Passport Alerts Register. As a result, a passport application may be denied or the passport must be surrendered. Rowie Stolk, PhD candidate at the Department of Constitutional and Administrative Law, spoke on…

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.

The Dutch Passport Alerts Register (Register paspoortsignaleringen, RPS) lists Dutch nationals (around 8000 in 2021) whose right to a passport has been restricted. As a result, they cannot apply for, renew, or must surrender their passports. Under the Passport Act, the Tax Authority, the DUO (Education…
