First-year Public Administration students write consultancy report for municipality The Hague

The starting point of human-induced landscape changes has been under permanent debate. It is widely accepted that the emergence of agriculture strongly increased human impact on their environments. However, foragers can and do actively transform land cover and ecosystems. Ethnographic observations,…

Scientists' computers are now full of complicated 3D models, but no standard has yet been developed for exchanging the data. A new database should change this. External PhD student Liselore Tissen is receiving a grant to contribute to this on behalf of Leiden University (and TU Delft). ‘It will be great…
