Drought, one of the most pervasive climatic phenomenon in India, is caused by a number of factors. There are four major reasons for drought in India- delay in the onset of monsoon/ failure of monsoon, variability of monsoon rainfall, long break in monsoon and areal difference in the persistence of monsoon.
What are the major causes of drought?
Droughts are caused by low precipitation over an extended period of time. Atmospheric conditions such as climate change, ocean temperatures, changes in the jet stream, and changes in the local landscape are all factors that contribute to drought.
What are the causes and consequences of drought in India?
High temperature and low rainfall is causes of drought. Hot winds, low humidity, and high evaporation affects the drought. Drought are arise due to the lack of water supply and water resources. … Its duration may increase with high temperatures and dry conditions.
What are the causes and effects of drought?
When rainfall is less than normal for a period of weeks to years, streamflows decline, water levels in lakes and reservoirs fall, and the depth to water in wells increases. If dry weather persists and water-supply problems develop, the dry period can become a drought.
Where does drought occur in India?
In parts of India, failure of the monsoons causes water shortages, resulting in poor yields. This is particularly true of major drought-prone regions southeastern Maharashtra, northern Karnataka, Andhra Pradesh, Odisha, Gujarat, Telangana, and Rajasthan.
What are the effects of drought in India?
The drought in India has even led to increased suicide rates among crop growers. Additionally, the heat wave and drought impact the ability of Indian children to attend school. Schools in some areas have been shut down due to excessive heat and lack of water.
Which part of India is most prone to drought?
Rajasthan is one of the most drought prone areas of India. Eleven districts of the state are in arid regions including Jaisalmer as the driest district.
What are the causes of drought Class 6?
Droughts are caused due to lack of rains. Drought condition results in drying up of wells, lakes, ponds and thereby creating water scarcity. Droughts result in the evaporation of water from the soil leaving the soil dry and patchy. Droughts result in mass death of plants and animals due to dehydration.
What are the main causes of drought class 8?
Some causes of droughts are deforestation, loss of biodiversity and excessive use of ground or surface water. Drought is one of the most widespread disasters that India faces, since it affects more than 70% of cultivable land.
What are the causes of drought and desertification?
2.1 Causes of drought and desertification
The resultant effects of drought are exacerbated by human activities such as deforestation, overgrazing and poor cropping methods, which reduce water retention of the soil, and improper soil conservation techniques, which lead to soil degradation.
What are the causes and effects of drought Class 6?
Causes of Droughts and its Effects
The level of water in the ponds and rivers goes down and in some cases water bodies get dried up completely. Groundwater becomes scarce and this leads to droughts. In drought conditions it is very difficult to get food and fodder for the survival.
