Managing scarcity to serve the public interest is a classic government task. An important way to execute this task is by allocating individual rights that are only available in limited quantities, such as CO2 emission allowances, gambling licences, subsidies, radio frequencies, public contracts and…

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

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.

How can ecosystem services within river catchments be quantified in spatial and temporal explicit way?

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.

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.

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.

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

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.

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.

New digital methods and a data explosion are radically changing archaeological research. Karsten Lambers, Associate Professor of Archaeological Computer Science, tells us all about it.

CML-researcher Rene Kleijn has spoken about metals scarcity in relation to the energy transition in a new Dutch popular scientific TV show called

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:…

“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.…

Interview in the popular journal for the agricultural sector Nieuwe Oogst with CML-researcher Martina Vijver about the Dutch policy on pesticides and it’s possible conflicts with the aims for clear surface and groundwater.

The Water Resources and River Management course (300-level) took a day long field trip to exotic… South Holland! Here students were able to examine a variety of ways in which densely populated deltas confront issues related to water management and flooding, from a Dutch perspective.

It may well be possible to remove nitrate from polluted groundwater and at the same time produce ammonia in a sustainable way, according to PhD candidate Phebe van Langevelde and Professor Marc Koper of the Leiden Institute of Chemistry in Joule on 26 January. Together with a German colleague, they…

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…
