The 12th World Congress of the European Water Resources Association (EWRA) on Water Resources and Environment, under the theme "Managing Water-Energy-Land-Food under Climatic, Environmental and Social Instability", will be held in Thessaloniki, Greece, 27 June - 1 July 2023 (EWRA2023). The 12th World Congress EWRA2021, scheduled to be held in 2021, was postponed due to the worldwide negative developments of the CONVID-19 pandemic.

The aim of the Congress is to discuss innovation in water resources management to address current and future challenges: growing uncertainty, greater extremes, increasing demand, water scarcity and global change. While traditional management practice is still effective, new technologies and approaches are emerging to better protect, regulate, allocate and recycle water resources. Sustainable management of water resources in the 21st Century requires a comprehensive understanding of the interaction of complex natural and social components in a changing context. The Congress will seek scientifically sound and economically-efficient solutions that are environmentally friendly, socially acceptable and climate-proof.

The Congress intends to be a forum for scientists and engineers from diverse cultures around the world to discuss their understanding of water resources systems at a diversity of scales and to promote environmentally sustainable water resources management.

A wide range of topics addressing the most critical aspects of water resources management will be presented in the Congress. We welcome contributions from researchers from all aspects of water resources management who are keen to look beyond their research perspective and who like to discuss their research findings in relation to other approaches
