What is it all about?

Participatory GIS (PGIS) is an emergent practice in its own right developing out of participatory approaches to development and spatial information management and communication.

The practice is the result of a spontaneous merger of Participatory Learning and Action (PLA) methods with Geographic Information Technologies (GITs).

A practice …

That builds on visual language, multimedia, and multiple spatial dimensions …

That integrates local spatial knowledge (LSK) with other data

Wherein geo-spatial tools, methods and technologies are integrated

That relies on multidisciplinary teams, skills and approaches

Synergetic with Participatory Video (PV), Web 2.0 and social media applications

In which contexts?Community-based planning and management

Awareness raising, education and social learning

Communication and advocacy (policy making)

Climate change adaptation

Community-based Disaster Risk Reduction

Management and amelioration of territorial conflicts

Self-determination

Safeguarding ever-evolving intangible cultural heritage and identity building

Participatory 3D Modelling (P3DM)

… with local spatial knowledge (ISK)

P3DM works best at scales

larger than 1:10,000

merges traditional spatial information …

P3DM facilitates visualizing mental representation of space

Participatory 3D Modelling in Samoa: Triggering behavioural changes and climate change resilience

“The study demonstrated that P3DM contributes to natural resource management and climate change resilience and showed the transformative power of the approach at various levels, such as community, NGO and governmental level. Through the P3DM process, meaningful interactions between government representatives and community members resulted in greater collaboration and mutual learning. While government representatives have changed the way they approach local communities – from ‘teaching’ to ‘listening’ – communities have also changed their attitude towards land management and development.”

The first one was done in Fiji in 2005

Who will gain and Who will loose?

“GIS turns local knowledge into public

knowledge and out of local control.

This can be used by outsiders to locate

resources and development needs, or merely,

to extract more resources, or to increase control

from the outside.”

PGIS applications may be used to legitimise

decisions which in fact were taken by

outsiders
