Support the spread of “good practice” in generating, managing, analysing and communicating spatial information Introduction to PGIS Practice By: Giacomo Rambaldi Unit: M01U01
Flow of the presentation Historic perspective About Participatory GIS (PGIS) practice Communication as a key ingredient Contexts Building on indigenous spatial knowledge The importance of the “P” Tools, methods and technologies in the practice Enabling and disabling environments A range of implications

Historic perspective 1980s –Participatory Rural Appraisal (PRA) methods Ground and sketch mapping, transect mapping 1990s –Innovative geographic information technologies Geographic information systems (GIS) Global positioning systems (GPS) Remote-sensing image analysis software Open access to online spatial data and imagery
About participatory GIS practice Participatory GIS is an emergent practice It merges: –Participatory Learning and Action (PLA) –Geographic information technologies –Communication / media –Web 2.0 applications
About participatory GIS practice The practice is geared towards community empowerment through applications of geospatial technologies that are: –measured; –demand-driven; –user-friendly; –integrated.
Communication: key ingredient Producing, georeferencing and visualising indigenous spatial knowledge helps communities: –engage in peer-to-peer dialogue; –promote their issues and concerns with higher-level authorities; –address economic forces.
Contexts Self-determination Management and amelioration of conflicts Collaborative research Collaborative resource-use planning and management Intangible cultural heritage preservation Identity building
Contexts Good governance Raising awareness and assisting with education and social learning Community-based hazard management and risk reduction Promotion of equity
Building on indigenous spatial knowledge Resource distribution Resource use, control and access Places of historic, cultural and religious significance Indigenous names, cosmovisions, creation and origin myths, etc. Hazard perception
The importance of the “P” Genuine bottom-up participation should cut across the process in: –understanding existing legal and regulatory frameworks –setting project objectives –defining strategies –choosing appropriate mapping methods –gathering, managing, analysing spatial data –communicating, networking and advocating
Tools, methods and technologies Ground and sketch mapping (M08) Participatory scale mapping & surveying (M09) Participatory 3D modelling (M10) Participatory mapping using aerial and remote- sensed images (M11) GIS for practising PGIS (M12) Participatory Internet-based mapping (M13)
Enabling and disabling environments Legal and regulatory frameworks Attitudes and behaviours Physical environments (e.g. infrastructure) Skills Human and financial resources Locus of control on the process Locus of control on access and use of data (i.e. knowledge is power)
A range of implications Participation: genuine – no window-dressing Ethics in the practice: a must! High-tech versus low-tech: a blend? Some key questions: –Whose GIS is it? –Whose questions are addressed? –Who sets the agenda? –What will happen when experts leave or when donor funding dries up? –What is left with those who generated the data and shared their knowledge?
