The International Rubber Study Group (IRSG), with the International Rubber Research and Development Board (IRRDB), the CGIAR research program on Forests, Trees and Agroforestry (FTA) led by CIFOR, and the French Agricultural Research Centre for International Development (CIRAD), ran an open digital workshop on natural rubber systems and climate change on 23–25 June 2020, attended by more than 500 scientists and stakeholders. The purpose of the workshop was to review recent research results on impacts of climate change on rubber production, potential means of adaptation and contribution to mitigation of climate change, and to identify knowledge and research gaps as well as recommendation for action. This document brings together the extended abstracts of the presentations and summaries of the discussions held during the workshop.
