Biodiversity
Gavkhouni, an ancient marsh with highly saline water and uniquely adapted wildlife, is located in the eastern part of the city.
The Isfahan Department of Environment was established in 1972 to conserve biodiversity. Two national animal conservation parks are nearby: Kolah Ghazi Park in the southeast, and Ghamishloo park in the northwest.
Water
Some 10 kilometers of canals and aqueducts crisscross the area. 14 water tunnels service Isfahan. Other water projects related to the city are the Yazd Water Transfer Pipeline, the Koohrang river tunnels, Kouhrang 2 Hydroelectric Power Station, Kouhrang 1 Dam, and Kouhrang 3 Dam.
The city relies on wells and the Zayanderud dam as its main sources of potable water.
Drought
Much of Isfahan's water management effort is devoted to combating drought. For example, the city has switched to xeriscaping lawns in a response to water scarcity. By 2020, 52% of city green space (1820 hectares) was maintained with micro-irrigation, a low-pressure water system designed to minimize water use.
Waste
Isfahan's population of 1,980,000 people creates almost 864 tons of waste daily, or 436 grams per citizen. The Isfahan compost fertilizer factory recycles 650 tons of waste each day and ranks first in the country.
Of the city's 5200 hectares of green space, 35% is irrigated using reclaimed wastewater. The city's main wastewater treatment plants are located in Sepahan Shahr (south) and Shahin Shahr (north).
Air quality
In 2013 Isfahan had only two days of clean air. 13 sensor stations measure its air quality.
