Presentation Transcript

  1. Geographical information systems Catherine Pfeifer ILRI/IWMI & Yenenesh Abebe IWMI

  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. 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. 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. What is GIS ? • Geographic layer = geographic data • Vector data • Point • Lines • polygons • Raster data • grid

  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. 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. 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.
