By reforming agriculture in targeted areas, we can protect the Natura 2000 areas much more effectively. This is what Jan Willem Erisman of Leiden University and Ton Brouwer of Gispoint consultancy write in a new report. They have created a special, nitrogen map of the Netherlands that shows the areas…

More than 80 percent of the EU’s agricultural subsidies go to the production of animals or animal feed. These products are responsible for 84 percent of the EU’s food-related greenhouse gas emissions. That is revealed in a new study by three Leiden researchers published in Nature Food. ‘If we continue…

It is difficult to imagine a society other than a hierarchical nation-state. This is in part because we neglect alternative forms from the past, argues archaeologist Lewis Borck in the Journal of Contemporary Archaeology.

Bioenergy with carbon capture and storage (BECCS) is a promising method for removing carbon dioxide (CO2) from the atmosphere and simultaneously generating energy. Yet this method is controversial, as it may require a great deal of land and water. Researchers at Leiden University have now proposed a…

More efficient use of phosphorus fertilisers would make it possible to meet food demand in 2050, without using more of the world’s land for agriculture. This is what environmental scientists José Mogollón and colleagues have discovered by working out various future scenarios for food production and…

Scientists and students from Leiden University, together with farmers and citizens, investigate how to manage peatland in a sustainable and profitable manner. A great opportunity for students to experience how scientific knowledge…

The new Dutch government must act quickly to take rapid, far-reaching measures in three specific regions to tackle nitrogen emissions. This will create the space for a long-term strategy to deal with other urgent problems and the knot of obligations that the state will need to untangle. These are the…

‘It is recommended that the State assumes sovereign responsibilities to protect life, liberty and property of its citizens in the domain of cyberspace, despite the international character of cyberspace,’ says Roy van Keulen. He will defend his dissertation on digital force on Wednesday 9 May 2018.

From 9 September onwards, Leiden scientists, citizens and farmers will jointly investigate how to sustainably manage peat meadowland. In ten years' time, they hope to have learned how to promote biodiversity and simultaneously reduce nitrogen and CO2 emissions, among other things. The research will…

Researchers from the Institute of Environmental Sciences of Leiden University started crowdfunding to raise 15.000 euro to build a laboratory in nature: The Living Lab. This is necessary to test the effects of chemical compounds in a natural situation.

Chemical substances and nanomaterials are processed on a massive scale in diverse products, while their risks have not been properly assessed. Time and again synthesised substances have been shown to pollute the environment more than lab tests predicted. This is the warning given by Professor of Ecotoxicology…

On average, Dutch breeding birds have become more numerous in the period 1980-2010. The common species have even done better than birds in other European countries. Farmland birds are an exception: they declined sharply both in the Netherlands and elsewhere in Europe.

A plant-based diet could improve the resilience of our food system. Moving to such a diet in the European Union (EU) and United Kingdom (UK) alone could replace almost all the production losses from Russia and Ukraine. That’s what an international team of researchers conclude in Nature Food. Leiden…
