In the last 30 years, there have been progressively more dry and rainy years, a reduced presence or even absence of snow cover, an increase in air temperature, large-scale fires, intensified glacier melting, and the like. Climate change certainly has an effect on all areas of economic activity, but its largest impact is on water resources and existing ecosystems. One of the most important water resources is groundwater, on account of which more than 70% of the population of Serbia meets its water demand. Based on the rate of abstraction, intergranular aquifers are the largest source of groundwater, followed by karst springs and fractured aquifers. The vulnerability of groundwater to climate change varies. An unconfined intergranular aquifer suffers from climate change because of its shallow water table (higher rate of evaporation, less recharge, smaller reserves, poorer quality, etc.). Confined intergranular aquifers, however, are not directly exposed to the impact of rising temperatures. Finally, one of the most important groundwater resources is karst spring water, like that found in the karst massifs of eastern and western Serbia. The absence of settlements, roads, and intensive agricultural activity in these parts is one of the main reasons why the quality of karst groundwater is high and suitable for water supply, given that often only chlorination is required. The advantage of these waters over other resources is that groundwater levels are at great depths, so an increase in temperature will not have a significant effect on evaporation. The paper provides a detailed overview of the pressures of climate change on groundwater, with a focus on karst groundwater.
