The water challenge cannot be solved in isolation. Quality, quantity and access to water are affected by a myriad of factors and at the same time their impact is felt across many sectors. The complexity of the water challenge underlines the importance of good governance and cooperation across sectors. This Task Force meeting explored the interconnections between water and energy, agriculture and environment to demonstrate the complex nature of the water challenge and looked at what action is needed in the different sectors as well as the responsibilities of stakeholders at the different levels in order to improve management of water resources in the EU and beyond.
