Surface water intake for energy production and irrigation has resulted in almost all rivers being under great direct and indirect anthropogenic pressures (e.g. reservoirs that have been built on some rivers), also, pollution of groundwater due to agricultural and forestry activities (widespread use of chemicals) threatens especially endogenic fauna and aquatic organisms. The ecosystems situated in karst landscapes are also very vulnerable to climate change, and they are subjected to other intensive anthropogenic pressures at the same time. Among them, wetlands karst fields are particularly sensitive to the impacts of climate change.
