Why? Changes to Earth’s freshwater systems are central in global change. They affect people and ecosystems. We want to understand the water systems and their changes, and contribute to improve freshwater security, and help protect and restore water environments and ecosystems.

How? We study water quantity and quality, and how water flows and carries other substances and energy through the landscape – locally, regionally and globally, and from past, through present, to future times.

What? We study soil water and groundwater, lakes and rivers, wetlands and water use by vegetation, engineered water systems, permafrost and glacial water – separately and linked in hydrological catchments, landscapes, water management districts – in different parts of the world.

Our study sites around the world.
