Deserts of Iran; the Ecological & Living Conditions
Iran is situated on a high-altitude plateau surrounded by connected ranges of mountains. The well-known deserts of Iran are in two major regions:
1) Dasht-e-Kavir, and
They are both some of the aridest and maybe the hottest areas of their kind in the world. A lot of people in the world think of Iran as a country covered by deserts, but this isn’t true. Only parts of Iran are as such. Here you will learn about this natural phenomenon in more detail.
The Desert Pits of Iran
Many who have read about the deserts of Iran have definitely come across Kavir-e-Lut name. Kavir-e-Lut is the largest pit inside the Iranian plateau and probably one of the largest ones in the world. Kavir-e-Lut is a pit formed by broken layers of the earth.
The maximum annual rainfall is approximately 100 mm there. The average altitude of this desert is almost 600 m above sea level (ASL) and the lowest point near “khabis” is almost 300m ASL. In Kavir-e-Lut, a large amount of sand is always moving southward forming sand hills and running sand masses.
Dasht-e-Kavir is a geological pit almost north of Kavir-e-Lut. The minimum altitude of this desert is 400 m ASL. The major part of Dasht-e-Kavir is covered by sand and pebbles and exposed to strong winds and storms that set salt-combined sand in motion like sea waves. At times, this phenomenon forms long sandhills of 40m high.
From the structural point of view, Dasht-e-Kavir is very much different from Kavir-e-Lut. The difference in temperature between days and nights during a year in Dasht-e-Kavir is between 0 and 70 degrees C.
The Ecological Conditions of Iran Deserts
Some of the ecological features of the deserts in Iran are strong sunshine, relatively little humidity, little rainfall, and excessive vaporization. Depending on how far a point is from higher altitudes, the temperature is varied.
A point far from altitudes can reach up to 60 degrees C during summer. The average temperature during January and May is 22 degrees C and 40 degrees C respectively. In general, the ecological conditions of the deserts in Iran are so severe that they are not tolerable either in summer or winter.
It rarely snows there. The annual relative humidity is below %30. During summer, it decreases, at times, down to %0. It usually rains during winter and sometimes showers lead to washing away the earth. It goes without saying that there cannot be proper enough soil and water for plants to grow. Since these regions are always open to winds and there are not sufficient plants to preserve soil, wind erodes the earth and brings about losses. Therefore, blocking winds with wood-made walls and planting shrubs and trees are carried out to confront the destructive natural forces.
Living Conditions in Deserts of Iran
It is always water that determines living conditions everywhere. Again it is just water that helps plants grow and people stay in an area within the desert. Water is not easily accessible at every corner of the deserts of Iran.
Life goes on in the areas where water can be found in springs or through the ancient technique of making underground aqueducts called kariz (qanat). At times, semi-deep wells are dug to get water. So, desert dwellers make the most of the minimum water they get. Local people use highly tolerant animals, camels, to travel through the desert. Usually, vines or similar trees with deep-going roots are planted so that they could survive.
Making a Living in the Deserts
People live only in oases on small scales and they rely on farming, herding animals, and migrating. They have to plant wheat, barley, fruit trees, and alike. In some areas, farming is also in vain. So, they have to make a living just by herding cattle. When neither of the above helps, they have to migrate somewhere else in search of better living conditions.
Accommodation & Clothing
Sun-dried brick, raw mud, and in some areas a limited quantity of stone are the only constructional materials used to build houses. Walls have to be built very thick for the sake of insulation and roofs have to be built in cupola or vaulted forms to last longer.
People are usually dressed in bright colors and clothing is mostly made of cotton. They are loose and long unless people are influenced by the city dwellers’ culture.
Although the Iranian plateau forces its compelling situations, its inhabitants struggle for preserving living conditions. These hard-working people, who have been struggling for thousands of years in the deserts of Iran, will not give up so easily.
I’ve noticed large circular berms in the desert north east of Qom. What are these for.
Thanks I love Iran.
Hi Tj. I need to see what you’re talking about. Can you send me a photo so that I can see it too?
