An interim evaluation was useful to adjust the final evaluation design. As a result of the interim evaluation, a few changes are being made to the overall evaluation design to make it more cost-effective. The interim evaluation used qualitative and administrative data to review results two years after the project. Since the interim evaluation found that levels of irrigation were clearly lower than expected, a large interim quantitative survey was cancelled. The knowledge gained by the quantitative survey would not have warranted the cost. In addition, learning that irrigation levels were partially low due to weather (rainy years), solidified the importance of collecting information on multiple agricultural years for the final evaluation.
