RS & GIS applications to manage irrigated agriculture

3,080 views

Published on

Remote sensing (RS) and geographical information systems (GIS) are revolutionising irrigation management. They represent a relatively cheap and rapid method of acquiring up-to-date information over a large geographical area. and are the only practical way to obtain data from inaccessible regions. At small scales, regional phenomena which are invisible from the ground can be clearly visible. Presented at the 1st World Irrigation Forum, 2013, Mardin, Turkey.

RS & GIS applications to manage irrigated agriculture

  2. 2. www.iwmi.org Water for a food-secure world If you can’t measure, you can’t manage! • Relatively cheap and rapid method of acquiring up-to-date information over a large geographical area. – Example: Landsat scene covers 180 km x 180 km at ground resolution of 30 every 16 days • It is the only practical way to obtain data from inaccessible regions, – Example: Antarctica, Amazonia. • At small scales, regional phenomena which are invisible from the ground are clearly visible. – Examples: faults and other geological structures. A classic example of seeing the forest instead of the trees.
