On 27 April 2018, hundreds of farmers and their family members laid a siege to the Salem collectorate to protest against land acquisition for airport expansion in the city . The primary reason for the protest has been the safeguard of the land and livelihoods. The proposed expansion of the airport requires 567 acres of land. The land for the initial airport was acquired in 1989 from the parents and grandparents of those protesting now. When the Salem district administration began formalities to acquire lands for the expansion, the farmers and the residents strongly opposed. They also urged the district administration and chief minister Edappadi K Palaniswami to drop land acquiring activity even as they were assured of huge amounts in compensation. The officials assured the land owners and the farmers that they would give four times of money than the government's guideline value. "But, we are not struggling for money and we protesting to save our livelihood," the farmers said.
