Aims of this project were to study the interplay between climate, catchment properties, water chemistry and aquatic communities in Yunnan region in China and in subarctic regions in Finland and Norway. Our aim was also to learn how to identify important water sources for multiple services (i.e. drinking water, irrigation and aquaculture) in poorly developed areas and how the quality of these water sources will change in a changing climate. We also examined how catchment properties can be used to identify regions of high aquatic biodiversity.
We showed that water quality is the major determinant of biotic communities in mountain regions in China. Therefore, retaining good water quality would be important for biotic communities and for ecosystem functions.
Project will give new information about water quality in poorly developed regions in China – this will be very important for local people who can in the future consider more precisely how limited water supply is best conserved.
