23 Stakeholder meeting on water scarcity and droughts Brussels, 27 April Way Forward for EDO Continuous testing and improvement of the indicators already regularly produced. Implementation of additional drought information and water availability indicators (e.g. low flows, snow cover) Implementation of a composite drought indicator. Inclusion of drought information produced by national and regional authorities.
