There were presentations on fuel, wildfires history in Barcelona, the use of caves as pens and one on the Mercat del Born.

At IPHES (Institut Català de Paleoecologia Humana i Evolució Social), these disciplines are important and for these reason the Archaeobotany Seminar which reaches its third edition this year, is organized. As usual three sessions usually held in Spring are planned, but this year, the COVID-19 crisis has obliged to postpone two of them (field trip and a laboratory activity) to next autumn. However, the session devoted to the presentation of research work in progress or already completed has been carried out virtually. The people attending the seminar were connected from Barcelona, Mallorca, Germany, Portugal and Tarragona.
