Abstract
Citizen science networks can provide support and visibility to existing initiatives. Although citizen science is a growing practice in Brazil, several challenges still exist. A network can play an important role in overcoming these challenges, helping with the exchange of knowledge between initiatives or raising funding, for example. The Brazilian Citizen Science Network was created to advance citizen science in the country. The launch took place in March 2021 at a two-day online workshop focused on topics such as financial sustainability, technology, data quality, inter- and transdisciplinary infrastructure, engagement, and good practices. Based on the contents of the presentations and comments during the event, the authors of this report held follow-up meetings to identify favourable and unfavourable factors that can foster or constrain citizen science in Brazil. Afterwards, an open letter expressing these factors was produced and shared with the network members to register the status of challenges and opportunities we have discussed so far, to be used as a guide for future actions. This report provides an overview of the workshop. Despite depicting a local perspective, the challenges and opportunities discussed during the workshop and summarised in this report may also apply to fostering citizen science in other countries or establishing global practices. We consider that the Brazilian Citizen Science Network can play an important role in promoting the establishment of collaborative actions across the country.
