Geographical information systems

This document explores Geographic Information Systems (GIS) and their significance in agriculture. It introduces the concept of GIS, which integrates geographic and information systems, focusing on its capability for suitability analysis. The Nile-Goblet tool is highlighted as an open-source resource for users to conduct suitability assessments without prior GIS experience. With its user-friendly interface, the Nile-Goblet tool enables analysis based on specific agricultural practices and environmental conditions, particularly tailored for the Ethiopian Blue Nile region.

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.
