Editor
Wageningue University is located in Wageningue, the Netherlands. Its campus is located on the outskirts of the city, which allows it to plan numerous extensions to its premises, all of which are already ultra-modern, due to its scientific nature. The university focuses on life sciences, sociology, business relations and natural resources.
In particular, the University is home to the Alterra Institute for multidisciplinary research into the artificial and man-made environment (rural environment, urban ecology, green spaces, green webs).
