The Participatory Mapping Institute actively collaborates with the International Society for Participatory Mapping. The Society strives to provide opportunities for underprivileged and marginalized communities in order to promote a more equal distribution of knowledge and resources. Here you can join the free network (Might Networks) to stimulate communication between practitioners and academics regarding participatory mapping: pmappingsociety.mn.co
Also, soon the society will be launching the International Journal of Participatory Mapping (IJPM).
