All of Gujarat’s polluted water is piped into the sea
Despite the existence of two departments, Environment and Climate Change, no research has been conducted.

The surface temperature of the Arabian Sea is rising by an average of 10.1 millimeters every year, leading to an increase in the number of cyclones. The number of cyclones has increased since the BJP government came to power. During the Keshubhai Patel government and the Narendra Modi government, 10 cyclones caused billions of rupees in damage to Gujarat. Farmers and the poor are the worst affected.
Seven major cyclones occurred during 1975-2000. 22 cyclones and depressions occurred during 2001-2025.
The Modi government established the Climate Change Department, but did not take any concrete steps by consulting meteorologists, marine experts, and environmentalists, or preparing a report. This is because 12,000 chemical industries in Gujarat are causing significant pollution, discharging their polluted water directly into the sea. This has caused significant damage to the marine ecosystem and ecology.
Gujarat is now being ravaged by storms and heavy rainfall. Over the past three decades, the forces of nature have become angry with Gujarat. It is the law of nature that you reap what you give.
The Arabian Sea has been a hotbed of cyclones for the past few years. The coastal regions around India are changing. Typically, the Bay of Bengal experienced more cyclones. Previously, the Bay of Bengal was warmer than the Arabian Sea.
Sea surface temperatures in the northern Arabian Sea have increased by 0.24°C per decade, while the global sea surface temperature is 0.13°C. The Arabian Sea’s surface temperature is rising at twice the rate of global sea surface temperatures.
The climate of coastal regions around India is changing. Cyclones have increased by 52% in the past two decades. The duration of cyclones has increased by 80%. Their intensity has increased by 20 to 40%. Cyclones in the Bay of Bengal have decreased by 8%. This increase has occurred in the warm Arabian Sea, which lies off the coast of Gujarat.
Chemical Industry
62% of the country’s total polluting petrochemical products are produced in Gujarat alone. Gujarat produces 98% of the country’s soda ash, 65% of plastics, 50% of chemicals, 40% of silk, and 70% of denim (jeans).
Industrial Sector
Gujarat has 232 industrial areas—GIDCs and private industrial areas—spread over millions of hectares. There are 90,000 industrial units. Of these, 12,000 are causing severe air, water, land, and sea pollution. In the pursuit of economic development, the BJP and allied governments have compromised our health and natural disasters over the past 33 years.
Polluting Industries
The 12,000 industries in Gujarat, six metropolitan cities, small towns, chemical industries, and refineries are dumping polluted waste, hot water, and contaminated water into the Arabian Sea. Is this not creating any new problems? This raises the question. Are Gujarat’s industries destroying agriculture, fisheries, traditional industries, and nature?
Sewage Water
The daily sewage generated by municipalities in Gujarat is approximately 5,013 MLD (million liters per day), equivalent to 169.932 million liters of water per day. It is estimated that only 25 percent of the sewage is being treated.
Water from Industries
Polluting industries in Gujarat discharge 16,092.44 MLD (160,920 million liters) of water daily. 16 billion liters of water is discharged. A large portion of this is being released into rivers, lakes, and oceans.
The ocean has warmed.
From 1980 to 2013, 28 intense tropical cyclones were observed along the Arabian Sea coast. Since 2013, 14 tropical cyclones have been recorded, of which 56 were intense events. This is double the number of events before 2013.
From 1980 to 2013, the intensity of tropical cyclones ranged from 20 to 25 kilotons per 24 hours, increasing to 40 kilotons per 24 hours between 2013 and 2023.
According to previous research, the frequency of cyclones has increased by 52% over the past two decades, while the duration of cyclones has increased by 80% and the intensity by 20 to 40%.
The number of cyclones in the Bay of Bengal has decreased by 8%. Between 1975 and 2000, there were seven major cyclones, while between 2021 and 2023, there will be more than 20 cyclones and depressions. The increasing frequency of cyclones is a matter of concern.
Cyclone Nilofar in 2014, Cyclones Chapala and Megh in 2015, Cyclones Vayu and Fani in 2019, Cyclone Tokte in 2020, Cyclone Biparjoy in 2023, Cyclone Asan in 2024, and Cyclone Shakti in 2025.
An increase of one to two degrees in sea surface temperature is associated with an increase in the frequency of cyclones. Five cyclones were observed in the Arabian Sea in 2019 and two in 2020.
Fourteen districts in Gujarat are highly vulnerable to cyclones. The government and the environmental department are not conducting any studies on this. Environmental changes are occurring due to global warming.
