Table of contents. PGIS is an evolved form of community mapping, the result of a spontaneous merger of Participatory Learning and Action (PLA) methods with Geographic Information Technologies and Systems (GIT&S). PGIS practice is based on using geo-spatial information management tools ranging from sketch maps, participatory 3D models (P3DM), aerial photographs, satellite imagery, readings obtained through Global Positioning Systems (GPS) and Geographic Information Systems (GIS) software as interactive vehicles for discussion, information exchange, analysis and support in decision making. If appropriately utilised, PGIS practice may have profound implications and stimulate innovation and social change. More importantly and unlike traditional GIS applications, PGIS aims at placing control on access and use of culturally sensitive spatial data in the hands of those who generated the data thereby protecting traditional knowledge and wisdom from external exploitation. The articles for this special issue were selected from papers presented at the Mapping for Change International Conference of Spatial Information Management and Communication held in Nairobi, Kenya, 7-10 September 2005.

Participatory Learning and Action (PLA, formerly PLA Notes) is the world's leading series on participatory learning and action approaches and methods. PLA publishes articles on participation aimed at practitioners, researchers, academics and activists. All articles are peer-reviewed by an international editorial board. See: www.planotes.org
