The National Program for Sustainable Irrigation (NPSI) required cost-benefit analyses to be undertaken on a number of its research investments from phase 1 of the program, which ran from July 2002 to June 2007. Eleven investments from phase 1 were identified by NPSI as having potential for analysis, and these were scanned by Agtrans using six criteria to further determine their suitability for analysis. As a result, four investments (projects) were selected for costbenefit analysis.
