| Summary, etc. |
This report presents the results of an impact assessment of rehabilitation intervention on irrigation system performance in the Gal Oya Left Bank irrigation system in Sri Lanka. The method of analysis was based on the time series intervetion analysis proposed by G.E.P. Box and G.C. Tiao. This model is used to separate the impacts of rehabilitation intervention in the presence of effects of both exogenous inputs and a dependant noise structure. Intervention impact assessment models were developed for several indicators of system performance in the Gal Oya Left Bank: irrigated area, irrigation supply per unit area, total irrigation supply, productivity per unit of irrigated land, and productivity per unit of irrigation supply. Results indicate that rehabilitation had substantial overall impacts on increasing the irrigated area and decreasing the irrigation supply per unit area. Though the impacts of rehabilitation on productivity are indirect, a large increase in productivity is also seen after rehabilitation. It was also evident that improvements in performance of these indicators in the Left Bank could not have resulted from physical or institutional improvements alone. Both physical and institutional components of rehabilitation intervention implemented simultaneously have contributed significantly to increasing the irrigated area. Institutional improvements contributed significantly in reducing the excess irrigation supply to the Left Bank |
