Environmental issues in Tehran

Last updated

Tehran, the capital city of Iran, suffers from severe air pollution, and it is located near three major fault lines, while being the most populous region of the country. The officials have created financial incentives to encourage around 5 million citizens to leave the city. On December 16, 2019 Tehran had its highest air pollution index of 181.

Tehran is rated as one of the world’s most polluted cities. Parts of the city are often covered by smog, making breathing difficult and causing widespread pulmonary illnesses. It is estimated that about 27 people die each day from pollution-related diseases. [1] According to local officials, 3,600 people died in a single month due to the hazardous air quality. [2] 80% of the city's pollution is due to cars. [3] The remaining 20% is due to industrial pollution. Other estimates suggest that motorcycles alone account for 30% of air and 50% of sound pollution in Tehran. [4]

In 2007, Iran imposed fuel rations but the plan has met little success in reducing the pollution levels. In 2011, with the improvements in the public transport system and the rise in fuel prices due to the new subsidies reform plan, the government is hoping to be able to improve the problems of pollution and traffic. [5]

The air pollution is due to several different reasons:

However, the government is engaged in a battle to reduce air pollution. It has, for instance, encouraged taxis and buses to convert from petrol engines to engines that run on compressed natural gas. Furthermore, since 1979, the government has set up a "Traffic Zone" covering the city center during peak traffic hours. Entering and driving inside this zone is only allowed with a special permit.

The government is also trying to raise people's awareness about the hazards of the pollution. One method that is currently being employed is the installation of Pollution Indicator Boards all around the city to monitor the current level of particulate matter (PM10), nitrogen dioxide (NO2), ozone (O3), sulfur dioxide (SO2), and carbon monoxide (CO). The board also displays the Pollutant Standards Index (PSI), which is a general indication of air quality based on the measurements of the above-mentioned five pollutants. The Pollution Indicator Boards classify the level of each pollutant as either safe, hazardous or dangerous.

In January 2017, Al Arabiya reported that pollution in Tehran has hit a dangerous level on the Air Quality Index. [8] On February 5, 2018 the Air Pollution Monitoring Center announced the air pollution index of the capital as 161 which is in the red zone. [9]

Earthquake

Tehran sits on two major fault lines, and it has been hit by over 1000 big and small earthquakes; although, the region has not been hit by a severe earthquake in the last 150 years. [10]

The city has been rapidly growing, and many buildings have been constructed without enough earthquake readiness. This is while there has been a 90% chance of an extent 6.0 or greater earthquake in the coming decades. [11]

Capital relocation

In 2010, the government announced that "for security and administrative reasons, the plan to move the capital from Tehran has been finalized." [12] The Iranian Parliament named Shahroud, Esfahan and Semnan as three of the main candidates to replace Tehran as the capital. There are plans to relocate 163 state firms to the provinces and several universities from Tehran to avoid damages from a potential earthquake. [12] [13]
