An appropriate database system is being developed under the guidance of the Data Advisory Committee. Similarly, ef<strong>for</strong>ts arealready underway to further develop ‘proto-indicators’.Observational Challenges <strong>for</strong>Indicator DevelopmentAfter decades of intensive experimental and modelling studies, ourunderstanding of hydrology at the local scale is arguably well inhand. In contrast, knowledge of the complex function of drainagebasins, especially in relation to anthropogenic challenges, is far lessdeveloped. The indicators developed <strong>for</strong> the WWDR must be able totrack the sources, transport, and fates of water as well aswaterborne constituents through large heterogeneous watersheds.On the one hand, there is the challenge of quantifying elements ofthe land-based hydrological cycle and moving progressively towardsthese larger scales; on the other hand, the dynamism associatedwith human-water interactions are all too often difficult tounderstand. The <strong>for</strong>mer has been the focus of major internationalobservational and scientific coordinating programmes (e.g. WMO-HYCOS, Coordinated Enhanced Observing Period [CEOP], Committeeon Earth Observation Satellites [CEOS], Global Terrestrial Network onHydrology [GTN-H], UNESCO-HELP [Hydrology, Environment, Life andPolicy]), but <strong>for</strong> the latter there are only a few monitoring systemsin place (CSD process through inputs from the United NationsAdministrative Committee on Coordination Subcommittee on <strong>Water</strong>Resources [UN ACC/SCWR] now reconstituted as UN-<strong>Water</strong>, GWP,World <strong>Water</strong> Council [WWC]). Similarly, while the deteriorating stateof current monitoring networks has been noted in the <strong>for</strong>mer case,a substantial build-up is also required to make them capable ofcapturing the system’s dynamism. In both, substantial improvementsare needed to overcome the observational challenges.Hydrologic in<strong>for</strong>mation baseThe need <strong>for</strong> hydrologic in<strong>for</strong>mation that can be used to developindicators has never been more timely. With the advent of highquality biophysical data sets, including those from remote sensingand operational weather <strong>for</strong>ecasts, the scientific community israpidly approaching a situation in which the hydrological cycle canbe monitored over large regions and in near-real time. Paradoxically,the trend of reduction in stations that routinely monitorhydrographic variables may greatly limit the usefulness of theseemerging high technology tools, since they ultimately requirecalibration against known ground-based standards in order to provetheir reliability.Our ability to monitor the terrestrial water cycle using traditionaldischarge-gauging stations – the mainstay of water resourceassessment – continues to deteriorate rapidly across much of theworld.
