The Water Cluster Lausitz e.V. (WCL) was founded in 2016 to accompany the transformation process in the water management sector associated with structural change in Lausitz. One of the main tasks is to secure the water resource, in terms of quantity and quality, under the conditions of climate change and mining, for the individual stakeholders in this and neighboring regions. Furthermore, the WCL aims to document the multifaceted knowledge and experiences in the field of water management and to contribute to problem-solving for water management in Lausitz.
