During 1946-1950 the Tebhaga movement in several parts of the 24 Parganas district led to the enactment of the Bargadari Act. Although the Bargadari Act of 1950 recognised the rights of bargadars to a higher share of crops from the land that they tilled, it was not implemented. Large tracts, beyond the prescribed limit of land ceiling, remained with the rich landlords. In 1967, West Bengal witnessed a peasant uprising, against non-implementation of land reforms legislation, starting from Kheyadaha gram panchayat in Sonarpur CD Block. From 1977 onwards major land reforms took place in West Bengal under the Left Front government. Land in excess of land ceiling was acquired and distributed amongst the peasants. Subsequently, “Operation Barga” was aimed at securing tenancy rights for the peasants. In Sagar CD Block 7,926.42 acres of land was acquired and vested. Out of this 5,680.89 acres or 71.67% of the vested land was distributed amongst the peasants. The total number of patta holders was 13,350.

The Sundarbans area, in the south of the district, includes 102 deltaic islands, out of which 54 are inhabited and the rest is reserved forest. The area spread over 54,000 km2 is home to 3.9 million people or around 40% of the population of the district. As per December 2001 census there were 271 Royal Bengal tigers and other animals in the Indian portion of the Sundarban forest, spread across 42,000 km2. The floor of the Sunderbans varies from 0.9 m to 2.11 m above sea level. Tidal saline water from the Bay of Bengal alternatively drowns and exposes the islands twice a day throughout the year. Around 3,500 km of earthen embankments, protecting the inhabited islands, have been facing the daily onslaught in a cyclone-prone area for more than a century. Clearing of the forests effectively started in 1781 and in about a century Hingalganj, Hasnabad, Sandeshkhali I and II, Minakhan, Haroa (all in North 24 Parganas district in 2016) Canning I and II, Jaynagar I and II, Mathurapur I and II, and Sagar (all in South 24 Parganas district in 2016) had been fully or substantially cleared of forests. Thereafter, much of the interiors of Kakdwip, Patharpratima, Basanti, Kultali and Gosaba were cleared for human settlement. People started moving in to the area. The refugees from erstwhile East Pakistan were the last to come in large numbers between 1951 and 1971. Canning I and II, Jaynagar I and II, Mathurapur I and II, Kakdwip and Namkhana are a little away from the forests and being attached/ connected to the mainland their conditions are similar to other mainland blocks in the district, but Basanti, Gosaba, Kultali, Patharpratima and Sagar are largely isolated from the mainland. These islands are mostly separated from the deep forest by a river. Electric connections are rare, and transport and communications, other than river transport, are not there. Around 95% people depend on rain-fed agriculture. Sagar lies at the mouth of the Hooghly, which carries fresh water and so things are a little different there. The sea level, around India, is estimated to be rising at 2.55 mm per year. In the last 70 years, 220 km2 of forest land has been submerged and the process continues.
Gram panchayats of Sagar block/panchayat samiti are: Dhablat, Dhaspara Sumatinagar I, Dhaspara Sumatinagar II, Gangasagar, Ghoramara, Muriganga I, Muriganga II, Ramkarchar and Rudranagar.
