Geospatial Data

Participatory Mapping Sessions

This unit has as its main purpose the development of a geospatial dataset. Data produced by activities in Units 1, 2, and 6 are organized in a geospatial format using Geographic Information Systems (GIS) to provide regional context for team members such that the scenarios can be readily applied to regional planning and resource management and used for dissemination purposes. The coordinator for this unit is D. Gauthier, with Technical Assistants Lorena Patino (Canada) and Andres Bodini (Chile). During the first 30 months the following geospatial data activities took place:

1. Technical assistance to unit teams: The search for available digital geospatial data sets, relevant to both the SSRB and ERB, is an ongoing process that also encompasses the re-formatting and updating tasks when appropriate. Current datasets collected include biophysical, social and economic topics. These are made available to all project researchers and assistants. Summary digital data sets for the SSRB and ERB are in development. Maps are updated as required and posted on the IACC web page as photo images in both jpeg format as well as downloadable pdf formats. GIS assistance has been provided in support of the development of a hydrological model for the ERB based on monitoring station data and watershed analysis. In consultation with project researchers, a number of working and final maps have been produced for use during fieldwork as well as for project planning and inclusion in documents. In addition, a collection of digital pictures of the study area has been gathered, organized and posted on the IACC web page for use by all project researchers and assistants. In Chile the GIS team has participated and supported the creation and compilation of an atlas of the ERB.



2. Integration of: (a) Regional context information; (b) Unit 1 material on vulnerabilities to climate variability; (c) Unit 2 material on impacts of climate change; and (d) Unit 6 material on indicators and frameworks: The development of a working chart of linkages of information between units according to dimensions of sustainability and exposure/adaptation issues is currently in progress. Information gathered in the ethnographic work in two of the selected communities (Stewart Valley and Cabri) has been used to create a cross-cutting chart template that links identified vulnerabilities, exposures, adaptation strategies, historical components and water conflict issues.
