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

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.

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

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

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

Select a location where given conditions for a best practice are met Example : terraces Slope : 12-50% Rainfall mm annual rainfall Not on vertisol

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.
