requirement estimation and planning tool. It aims to (i) verify 
            
70
SAPWAT3 program outputs, (ii) demonstrate SAPWAT3 to potential users,

and (iii) evaluate adoption potential using innovation adoption theory

background and rationale for disseminating SAPWAT3 widely, given its

enhancements such as a module to import crop data \u201cen masse\u201d

and a module to compare SAPWAT3 estimated daily evapotranspiration
