Dear Colleagues, We are pleased to announce that the international conference entitled “Air Pollution threats to Plant Ecosystems” will be held in Paphos (Cyprus) on 11-15 October 2021. This international event is co-organized by the Committee on Air Pollution Effects Research on Mediterranean Ecosystems (CAPERmed), the International Union of Forest Research Organization (IUFRO) and the International Cooperative Programme on Effects of Air Pollution on Natural Vegetation and Crops (ICP Vegetation). The conference, for the first time combining three events, will serve as an excellent example of effective international collaboration in the research of air pollution and plant ecosystems. Do not miss this cornerstone of international science. The CAPERmed IV meeting will be held on, back-to-back with the 3rd International Conference on "Ozone and Plant Ecosystems" and the 30th international biennial conference of the IUFRO Research Group on "Air pollution and climate change" on 11-14 October 2021. A full-day excursion is planned on 15th October 2021. All useful information are available online: https://cyprus2021.com<https://antiphishing.acri-cwa.fr/proxy/v3?i=SGI0Y… Deadlines Deadline for abstract submission : 1st September, 2021 All abstracts "accepted" in 2020 remain "accepted", a revised version can be sent by 1st September 2021.
