Towards a Water Scarcity and Drought Indicator System (WSD i S)

This project aims to develop a comprehensive indicator system for assessing water scarcity and drought, providing reliable information for decision-making. The system will be based on agreed indices and data, allowing for an annual EU assessment.

  1. Towards a Water Scarcity and Drought Indicator System (WSDiS) Maggie Kossida - Ifigeneia Koutiva - Christos Makropoulos National Technical University of Athens

  2. Objectives of a WSDiS • Reliable information base (@ appropriate temporal and spatial resolution) required for decision-making • Presentation of an annual EU assessment, based on agreed indices,indicators and data provided by MS and stakeholders to the COM or EEA on a yearly basis • a basis for assessment of WS conditions taking into account both demand, supply and availability issues (ie both socioeconomic and environmental dimensions)

  3. A framework for Drought and Water Scarcity Indicators • Drought and Water Scarcity • Capturing the reality of the Water Scarcity situation • A DPSIR Framework • Methodology for trialing the approach and logical testing: An sectors-based approach • Fact Sheets/ Situation Assessment for indicators and indices

  4. A basis for indicator development:The DPSIR Framework • The Driver-Pressure-State-Impact-Response: a thinking framework for the development and categorisation of indicators • Implies a certain causality • Allows for feedback loops

  5. Methodology for trialing the approach and logical testing • Need to ground the selection of specific indicators in the problem at hand, rather than proceed in selecting indicators abstractly. • Avoid long lists of indicators, which may have been “correct” but not necessarily relevant. • This complexity requires a step-by-step approach in developing indicators: allow questions of relevance and completeness to be answered throughout.

  6. A sector-based approach. • Water Scarcity, results from an imbalance between water availability, and water demand, in different sectors. • Suggestion: main water uses are identified and are used as a check list to develop a comprehensive (but relevant) Water Scarcity indicator system

  7. Supporting the indicators • Each indicator should be associated with three elements: • A Fact Sheet (explaining what is requested and why – specific parameter, resolution, rationale/SPI, methodology, metadata) • An Indicator Assessment (presenting a view of the spatial and/or temporal development/trends of the indicator in view of the phenomenon of interest (here: Water Scarcity). • Reporting guidelines (defining the format of how to report the indicator): link to SoE reporting sheets & DDs

  8. Process and current state (√) Domestic Water Supply Industry Other (e.g. tourism) Agriculture √ √ √ First comprehensive set of indicators for each use Data availability Survey (06.2009) √ √ ~√ √ Screened set of indicators for each use (narrowed down) Based on specific criteria (e.g. suitability, data availability, reproducibility, capacity if integration, clarity, diagnostic ability etc. PILOT RBDstesting Final set of indicators Assessments

  9. Agriculture • Linked to IRENA indicators as much as possible
