Iran is facing a severe water crisis, intensified by rising temperatures that accelerate evaporation from reservoirs, soil, and vegetation. Years of poor water management by authorities have compounded the problem, leading to overuse and depletion of vital water sources. Rapid population growth, urbanization, and industrial expansion have further increased demand, while government subsidies for agriculture have promoted inefficient water use. The consequences include dried-up reservoirs, deteriorating water quality, and collapsing ecosystems, making this one of the greatest challenges confronting the country today.
