The
Global Irrigated Area Mapping Project is part of IWMI’s
Comprehensive Assessment of Water Management in Agriculture to
define the current state of irrigation development. So, options for
intensification, expansion and land retirement can be investigated
in a realistic and spatially disaggregated way. Ideally this will be
able to explicitly account for water resource availability and
reliability.
Remote
sensing is identified as appropriate technique to achieve the goal
of this project. For that, Huge amount of high, medium and low
resolution remote sensing data are being used. To defeat the
different contexts of scale and climatic limitations to analysis of
remote sensing data, a number of parallel investigations are
undergoing to derive suitable techniques for mapping irrigated area
in different conditions. |
