Iran: Environment Overview

Iran's environment is characterized by its predominantly arid or semiarid climate, with subtropical conditions near the Caspian Sea. The nation is home to three notable geoparks: Aras, Qeshm Island, and Tabas, which highlight its geological diversity. Land use in Iran is varied, with 64.4% classified as 'other,' 6.6% as forested, and 29% dedicated to agriculture. Urbanization is significant, with 77.3% of the population residing in urban areas and a growing rate of urbanization at 1.32% annually. Iran faces several environmental challenges, including air contamination from vehicular and industrial emissions, deforestation, and desertification. Water management is crucial, as agriculture accounts for 86 billion cubic meters of water withdrawal annually, while the country possesses 137 billion cubic meters of renewable water resources. Iran's carbon dioxide emissions are significant, totaling 823.364 million metric tonnes in 2023, primarily from natural gas and petroleum consumption.
