Advances and research needs in irrigated system performance assessment

摘要

The last decade has seen an evolution in concepts related to irrigated system performance assessment. This evolution recognizes that performance measures can have different implications if studied at the farm, delivery system, project, or hydrologicbasin levels. Traditional agronomic, engineering, and economic perspectives on irrigation performance assessment need to be integrated with each other and with social, managerial, and institutional perspectives in order to clearly identify strengths andweaknesses of irrigated systems and develop sound strategies for their improvement. This paper reviews recent developments in irrigation performance assessment and identifies issues needing further research.
