Monitoring and Evaluation

According to the Global Water Partnership, a strong monitoring and evaluation system has the potential to ensure that an IWRM strategy meets its main objective of fostering positive change, and also that the strategy can adapt to evolving needs and conditions. Resources available in this sub-theme include examples of performance indicators, technical methods of hydraulic monitoring, handbooks for appraisal of management systems, and other resources that support the wide variety of approaches for monitoring and evaluating water resources.
