The Study on Strengthening NIA’s Management System
objective of the study is to formulate an Improvement
Plan for strengthening of NIA’s management system
aiming at more efficient and effective implementation
and operation of irrigation projects/systems, and
to carry out technology transfer to Philippine counterpart
personnel in the course of the study. In order to
do this, a comprehensive database must first be created
for all the irrigation systems that fall under the
NIA management. This GIS Database will be installed
in selected NIA Regional Offices to help them have
up-to-date information on their areas of jurisdiction.

specifications of the GIS were determined through
discussions with NIA’s personnel and upon the approval
of JICA Headquarters. The GIS maps created for this
study were in the scales of 1:50,000 and 1:4,000.
