Remote Sensing:A Miracle in Irrigation Management

Managing water for multiple benefits & between competing demands is occupying the minds of irrigators, catchment water managers & policy-makers. Remote sensing techniques are becoming powerful tools for efficient management of irrigation systems in large irrigated areas. This overview of the studies to date indicates that remote sensing-based monitoring of irrigation is at an intermediate stage of development at local scales. Remote sensing applications in irrigation management range from water availability studies in the catchment to the salinity studies in the command area. The objective of this research paper is to present the state of the art on applications of satellite remote sensing that support, management of irrigation systems & to identify emerging approaches that focus on future perspectives of research which may pave the way to operationalise the remote sensing techniques in practice.
