Consider the following statements regarding the efforts to combat desertification in Central Europe: I. The Homokhátság region in southern Hungary lies on the Great Hungarian Plain and is experiencing groundwater decline and increasing aridity. II. The intervention involves using cooled and purified overflow from thermal spas to flood low-lying fields and recharge groundwater. III. Thermal spring water proposed for flooding is untreated geothermal discharge, posing risks of contamination to soils and crops. IV. Artificial flooding is expected to increase surface evaporation, create a local microclimate, and potentially improve vegetation health in surrounding areas. How many of the above statements are correct?
