Changes in Saxony's hydrological budget were largely due to forest declineIn the past decades forest decline in Saxony caused major changes in the hydrological budget compared to climate change. An interdisciplinary research team of hydrologists, meteorologists and landscape ecologists of the Technical University Dresden, the Helmholtz Center for Environmental Research and the Max Planck Institute for Biogeochemistry in Jena analyzed 68 catchment areas over a period of 60 years (1950-2009).
The resulting data clearly show the effects of climate warming on the regional evaporation and the hydrological budget in Saxony. However, the main cause for changes in the water balance was found to be industrial air pollution. For the ridges of the mid-mountain areas the forest decline due to air pollution was the critical factor.
