Read the following passage and answer the item that follows. Your answer to this item should be based on the passage only.

A study modelling climate change impacts on the Krishna river basin found a projected rise in both maximum and minimum temperatures alongside a decline in the number of rainy days each year. These shifts are expected to alter the basin's hydrology, increasing surface run-off while reducing groundwater recharge, and worsening the frequency of droughts across the region. In response, farmers in the basin have increasingly turned to groundwater extraction to keep their crops irrigated through drier spells.

Which one of the following statements best reflects the crux of the passage given above?
