A Research Agenda for Participatory Mapping and PPGIS

Mapping with people

This illuminating Research Agenda opens up current debates and outlines potential developments in participatory mapping, an approach and set of practices relating to people’s spatial knowledge and dedicated to spatial and environmental justice. Leading experts analyse scientific, methodological, social-political-cultural and technical issues in participatory mapping and Public Participation Geographic Information Systems (PPGIS), emphasising ethics and good practice.

Investigating key issues, contested approaches and methodologies, researchers highlight the ethical dimensions of respect, safety and authority of knowledge. Chapters assess participatory mapping and PPGIS in citizen science and in affirming identity, with specific applications ranging from mapping indigenous culture and memories, to traditional land management and inclusive urban accessibility. Critiquing both innovative developments such as soundscapes and projection models, as well as established tools such as 3D modelling, remote sensing and phone apps, chapters also address meta issues, including evaluating outcomes of mapping applications and the impacts of AI.

A Research Agenda for Participatory Mapping and PPGIS is a valuable resource for scholars and students of geography, participatory research approaches and politics and public policy. Practitioners looking to implement PPGIS will benefit from its evaluation of current debates and potential developments in the field.

Participatory 3D Mapping (P3DM) Workshop in Guiuan, Eastern Samar, Philippines

Despite their ecological and economic importance, #BlueCarbon ecosystems such as #MangroveForests face multiple anthropogenic threats, from aquaculture expansions and pollution, to overexploitation and poorly planned restoration initiatives.


In Eastern Samar, local leaders, fisherfolk, and the youth are taking the lead, sharing the stories of their own communities through a three-day Participatory 3D Mapping (P3DM) Workshop, held February 25 to 27 in Guiuan, Eastern Samar. 

This initiative is led by the Institute for Climate and Sustainable Cities, in partnership with the Philippine Geographical Society of the University of the Philippines Diliman. It is organized under the Enhance Mangrove Ecosystem Restoration and Protection for Growth and Empowerment in Samar Island (EMERGE) Project, a two-year initiative to restore and conserve mangrove ecosystems in target areas in Eastern Samar and establish a sustainable, community-managed ecotourism site.

EMERGE is organized under the Tropical Forest Conservation Fund II (TCFII) of the Forest Foundation Philippines (FFP).
