Filipe Martins SJ, Director of JESC and Béla Kuslits, Ecology Officer, participated in the annual meeting of the HEST Ecology cluster of the Kircher Network, which connects different European Jesuit Universities. Members representing higher education institutions and Jesuit social centres reviewed past results, and planned for next year's main activities. The highlight of last summer was the publication of a booklet titled Wasting Food edited by José Carlos Romero and Jaime Tatay SJ and published by Cristianisme i Justicia. This document takes an interdisciplinary approach of the topic using environmental sciences, sociology, philosophy and theology to think about the root causes and possible solutions for such challenge. JESC will participate in the HEST Ecology efforts of collecting, organising and analysing sustainability projects, good practices and strategies, and making them publicly available in order to facilitate the sustainability transition of various institutions (universities, social centres and beyond) across the continent.
