Why a Policy Support System? Examples from the Andes BFP

  1. 1. Why a PSS? Policies are better when based on the science (natural and social), so how do we get the analysts to look at the science? - make it accessible, easily understood and relevant to their needs. What is a PSS (Policy Support System) : •combines best available data and knowledge of process (models), •integrated spatial database and test-bed for user policies or interventions •leaving the simplest possible messages without losing the important complexity of the data and the science, • a flexible and dynamic project legacy in addition to static data and publications, •visual and informative to a wide range of audiences, a learning and thinking tool •A clearly defined output requiring specific inputs (sub-models) from each WP in the BFP,
  2. 2. The SimTerra PSS framework and the AguaAndes PSS SIMTERRA User-base: expert knowledge (YOU ) SIMTERRA FRAMEWORK (Web and geo-browser based user interface) SIMTERRA SIMTERRA FRAMEWORK FIESTA, PATTERN... DATABASE (collection of tools (>2TB of global data for analysis and at 1km and 1ha resolution) Modelling) AGUA-ANDES
  3. 3. The AguaAndes PSS so far. It is different things to different people. The interface changes for scientists (detailed, shown), policy makers (less detailed)
  4. 4. Multilingual.
  5. 5. Scientist, English
  6. 6. Policy analyst, Spanish.
  7. 7. Interfaces with geobrowsers like Google maps....
  8. 8. ...and an embedded Google Earth
  9. 9. Shows the system being modelled...
  10. 10. ...with links to the subsystems (this is hydrology)...
  11. 11. ...and from there to the relevant part of the documentation (not yet written!)
  12. 12. You start by defining the area you want support for. The SimTerra database has 1 degree raster tiles (@100m resolution, shown) and 10 degree tiles at 1km resolution)
  13. 13. If you are logged in as a scientist you then access the simulation parameters which can be edited (collaboratively) in a Google spreadsheet (which AguaAndes then reads)
  14. 14. AguaAndes will then download all of the datasets necessary to run the simulation for your chosen tile. You can add your own data if you have better data.
  15. 15. The data are downloaded to your workspace on our servers (since AguaAndes runs on our servers not your local machine). Links are provided so that you can download any data which are not copyrighted or you can view the data in situ.
  16. 16. These are 3-hourly gridded rainfall series for your tile from www.kcl.ac.uk/geodata
  17. 17. This is 1km rainfall for your tile from the SimTerra database
  18. 18. This is 90m resolution elevation for your tile
  19. 19. ...geobrowsed
  20. 20. You can then choose from a set of policy options to implement
  21. 21. ...along with climatic or other futures
  22. 22. You can then run the simulation. We have added some of the hydrological models. You can set the simulation period (historic or
  23. 23. ...and run a simulation
  24. 24. ...accessing results in a geobrowser e.g. water balance for this tile around Lake Arenal, Costa Rica
