Technology transfer of SAPWAT3, verifying correctness of program output and evaluation of its adoption potential
Expanded Title:SAPWAT3 is essentially an enhanced and improved version of SAPWAT that is extensively applied and was developed to establish a decision-making procedure for the estimation of crop water requirements by irrigation engineers, planners and agriculturalists. SAPWAT has been developed through two consecutive Water Research Commission research projects as a further development of CROPWAT. The Water Research Commission funded and managed the SAPWAT-SAPWAT3 development over the past 15 to 20 years. The development of SAPWAT was followed by two technology transfer projects to demonstrate the application of SAPWAT on seven irrigation schemes. The application of SAPWAT and program shortcomings that have emerged during these actions has highlighted the importance of continuous upgrading and further development. This has led to the development of SAPWAT3 as an upgrade of SAPWAT through Project K5/1578 (TT 391/08). Development time and the cost involved heightened the need to disseminate knowledge of SAPWAT3 to as wide a scope of potential users as is possible. SAPWAT3 is the product of research related to irrigation, agricultural engineering, soil, crop, agricultural meteorology and agricultural. The acceptance of SAPWAT by more than 300 users in 13 countries shows that the program has qualities that make it acceptable to potential users, however the reasons for the adoption of the program have not been examined. It was therefore important to determine the characteristics that makes a program like SAPWAT acceptable as an innovation, because the results could be a indicator for the adoption of SAPWAT3. At the same time, the potential for adoption of SAPWAT3 needed to be determined to find out to what extent the more functional, and therefore more complex, program satisfies the characteristics that would enhance adoption. This short term technology transfer project also sort to include the expansion of functionality and correction of errors that have been identified in the SAPWAT3 program.
