Introduction to geographic information systems and the Nile Goblet tool

  1. 1. Catherine Pfeifer ILRI/IWMI and Yenenesh Abebe IWMI Learning Event on ‘A Decision Support Tool for Mapping Suitability of REM-Strategies in the Nile Basin’ Addis Ababa, Ethiopia, 6-7 December 2012
  2. 2. Plan  Crash introduction into what is GIS  Importance of GIS in agriculture  The concept of suitability  The Nile-Goblet open source tool  Test yourself the Nile Goblet tool
  3. 3. What is GIS  Geographic, so we know that GIS has something to do with geography.  Information, so we know that GIS has something to do with information, namely geographic information.  System, so we know that GIS is an integrated system of geography and information tied together.
  4. 4. What is GIS?  Computer system  Hardware  Computer, plotter, printer, digitizer • Software and appropriate procedures  Spatially referenced or geographic data  People to carry out various management and analysis tasks
  5. 5. What is GIS ?  Geographic layer = geographic data  Vector data  Point  Lines  polygons  Raster data  grid
  6. 6. GIS for agriculture  Technology/practices/crops depend on the bio physical environment  Best practices are location specific  GIS can inform what works where  Suitability analysis
  7. 7. Suitability analysis Select a location  where given conditions for a best practice are met Example : terraces  Slope : 12-50%  Rainfall 800-2000 mm annual rainfall  Not on vertisol
  8. 8. Nile Goblet tool  Open source GIS software for suitability analysis  No need for prior GIS knowledge  Dataset has been prepared for RMS in the Ethiopian Blue Nile  Flexible tool, can be adjusted for different location and different practices technologies.  http://nilebdc.wikispaces.com/Nile+Goblet+tool+and +training
