Dear Colleagues, We are pleased to announce that the 2nd edition of the Quarries alive International Conference will be held at the University of Liège, Belgium, June 24-26, 2020, with the theme “Quarries as opportunity for biodiversity and ecosystem services – A European approach”. The conference aims to create a bridge between quarry and biodiversity projects. The goal is to create an interdisciplinary gathering to exchange experiences from scientific research projects, technical engineering approaches and innovative pilot-studies focusing on the enhancement of biodiversity in quarries. We welcome all researchers, practitioners, stakeholders, as well as policy makers, to take part to this conference and share their knowledge. We challenge all actors of the quarrying activity, from ecologists to industrial stakeholders or NGOs working on fulfilling the demand for sustainable exploitation of ressources. The conference is a joint organization between the University of Liège (ULiège), the Belgian Extractive Industry Federation (FEDIEX), and the LIFE in Quarries project team.
