Irrigation system performance and its impact on crop productivity in Sri Lanka
This article analyses the performance of two irrigation systems in Sri Lanka, using performance measures adapted from Theil's mean-square forecast error concept. The performance is measured in terms of defined objectives that are decomposed into three components measuring adequacy, equity or dependability of water deliveries, and management capability. The relationship between the level of performance, as estimated by the above measures, and crop productivity is determined using regression analysis. The study demonstrates that input and institutional variables such as fertilizer, labour and power concentration have a positive impact on yields while poor irrigation management performance has a negative effect.
