  4. 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

  5. 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

  6. About participatory GIS practice • The practice is geared towards community empowerment through applications of geospatial technologies that are: • measured; • demand-driven; • user-friendly; • integrated.

  7. 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.

  8. Contexts • Self-determination • Management and amelioration of conflicts • Collaborative research • Collaborative resource-use planning and management • Intangible cultural heritage preservation • Identity building

  9. Contexts • Good governance • Raising awareness and assisting with education and social learning • Community-based hazard management and risk reduction • Promotion of equity

  10. 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

  11. 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

  12. 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)

  13. 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)

  14. 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?
