Effects of irregular monsoon in India

A monsoon is a seasonal shift towards the dominant winds in a region. Winds sweep from land to sea during most of the year to dry the air. This is happening when the ocean and continent differ in temperature. The sun is more rapidly warming up the land than large water bodies.

Climate change will not only influence India in the form of dramatic extreme events such as supercyclones. It is going to slowly but surely change the nature of major weather systems, like the monsoon, on which the country depends. A new study demonstrates the way the monsoon will become an erratic and destructive force through increasing global warming. German and U.S. scientists have investigated 31 different models for climate change in the Indian monsoon in accordance with various global heating scenarios. The researchers also found that monsoon rains are likely to increase every 1°C by 5 percent. Food safety is likely to be affected by any erratic change in the monsoon, among others. Crops need water in the first growing period, particularly but too much precipitation in other growing countries can harm plant species — including rice, which is supported by the majority of the population in India. The Indian economy and food system, therefore, are very vulnerable to volatile monsoon patterns. The newest study in three years has been the same as the future of the Indian monsoon. It is new research. The Special Report of the Intergovernmental Panel on Climate Change 2018 on The Ocean and the Cryosphere In A Change Climate (SROCC) state that through the 21stcentury the monsoon is going to be more erratic. The report predicts that dry spells will be longer and that heavy rain will alternate.

The monsoon affects the agricultural GDP of the country directly. Near to half of India’s food production comes from summer crops and a retarded or poor monkey is a source of supply problems and acceleration in food inflation. Sunlight heats both the surfaces of land and oceans during the summer months, but earth temperatures increase faster due to a lower heat capacity. Moist air is brought into the country as winds blow from the ocean. That’s why summer mountains make plenty of rain. In determining the growth and the inflation prospects of the Indian economy in a particular year, Monsoon arrives and its equality plays an extremely important role. In June and July 2015, however, the rainfall was 9 percent lower than normal in certain regions, with sharper deficits. Moreover, the remaining two months of the rainy season would have low precipitation of 84 percent, according to the Indian Meteorological Department (IMD) from August-September 2015.

The rebound is normal when the average long-term average drops from 96% to 104%. The Kerala monsoon has also experienced a 30% rain deficit this season, with rains traditionally far above the national average.
The rainfall has been flat so far so that while some areas have been excessively overflowing and even deadly, others have been drier. However, at least 35% of the country’s area appears to be in the deficient category on a rainfall map while 35% of the country has normal rainfall. There has been surplus precipitation in another 30 percent area.

Uniform monsoon impacts on different parameters Impact on development: Growth in the agriculture sector is expected to decrease by 5% compared to last year by the end of the current year. This also removes 0.7 percentage points from India’s overall GDP growth. This will damage demand in the non-agricultural sector as well.

Impact on Agriculture: India is a farming country with a survival of about 60 percent of its population and its contribution to GVA is also around 16 percent. It is impossible to overlook the importance of the monsoon. Rainwater accounts for 40% of the cropped area of our country. July is the most important sowing month and it is closely related to the production of food grain. Although cumulative rainfall is only 4.1 percent lower than normal (until 24 July 2015), we believe that rainfall will dampen food grain production to some degree in the first three weeks of July. The rice – the main staple Kharif – has made good progress due to the good rainfall to the northwest which accounts for 29% of rice output. Rice seeding has been badly hit in states like Andhra Pradesh and Telangana. The irregular distribution of showers has proven to be a problem as well as rain deficits, as in West Bengal where floods have affected rice seeds. However, the low levels of rain and reservoir in Maharashtra and Gujarat could affect coarse cereals, pulses, and olive seeds. Monsoon also causes soil to dry up in comparison with normal soil and also less water is needed for irrigation. All this will mean that production is reduced in Rabi or in winter.

Impact on rural demand: Unseasonal and pre-summer plants in regions that are already reeling from inadequate monsoons in March and April 2015 were damaged. The effect of India’s irrigation system will decrease in the second year of weak monsoon and impact agricultural production and farmers. Rural earnings have already fallen to around 8%. This affects rural demand adversely.

Impact on Food inflation: Poor monsoons may stoke food prices, steadily growing and retail inflation rises to 5.4% in June 2015, compared to a 4.8% increase in April 2015.

Impact on the FMCG sector: Poor monsoons have many harmful effects on the FMCG industry. Demand is falling – mostly in rural areas – and the cost of inputs is growing significantly. The current growth in FMCG sales in rural areas is about 11-13%, but the low monsoon could drag it down to 8-10%.

Impact on the electricity sector: As water levels in several hydropower dams will be lower than normal, less electricity is expected. Across 91 reservoirs 87.09 trillion cubic meters have been affected, down 13.2% a year earlier from 100.36 BMC, and even less than the average average average of 10 years of 90.68 BMC. During the intense temperatures of May and June, the rain will cool and the use of electricity will be increased without enough rainfall.

In today’s context, a multidimensional approach to permanently address monsoon deficits will need to an exploration of new drought-tolerant and climate-friendly crops, reducing rainfall-dependence by an increasing irrigation ecosystem, improving employment opportunities for poor non-farmers, improving farming gate capability, changing the agricultural to fork chain.
