WaterLOUPE - facing our local water risks

WaterLOUPE enables analysis of local risks of water scarcity and development of water scarcity solution strategies, taking into account the current situation and future developments and uncertainties.
The background map shows the Evapotranspiration Deficit Index (ETDI) for October 2017, as calculated with the PCR-GLOBWB and MODFLOW models developed at Deltares and Utrecht University. The blue-colored loupes indicate areas where a dashboard is available. The pink loupes indicate areas where a risk assessment has been done but a dashboard has not been developed, or areas that have yet to be published.

The WaterLOUPE initiative

On World Water Day 2018, research organization Deltares and Kimberly-Clark Corporation launched WaterLOUPE, a cutting-edge new tool to support water stakeholders in assessing water scarcity risks in order to generate actionable insights to adapt and/or mitigate local water risks. WaterLOUPE is a user-friendly dashboard that provides information on water scarcity risks and mitigation strategies for the current and future situation of your river basin. WaterLOUPE is based on the principle "Simplifying without compromising in terms of the content"

WaterLOUPE 1.0 - facing our local water risks

WaterLOUPE 1.0 enables analysis of local risks of water scarcity for different water use sectors, both for the current and future situation. Different climatic and socio-economic scenarios can be applied. It combines data on hydrology, exposure and vulnerability at the local level. WaterLOUPE runs a risk assessment for each actor-group separately, instead of providing one generic (average) risk assessment per basin. For example, it specifies between the impacts of water scarcity for self-subsistence farmers versus large farms. The distinction in impacts at actor level are key in establishing good and sustainable water stewardship in the catchment area.

WaterLOUPE 2.0 - building our water solution strategies

WaterLOUPE 2.0 is an extension that enables the development of mitigative and adaptive strategies to reduce water scarcity risk in the area of interest.  It provides a shared knowledge base about physical, environmental, economic, social, and political suitability of a variety of possible measures. Furthermore, for a predetermined set of combined measures, WaterLOUPE 2.0 shows the level of risk reduction that can be achieved by implementing these measures. The measures target increasing water supply, reducing water demand, and reducing vulnerability levels. The resulting expected risk reduction is again calculated for each sector and user group.
