The Hungry Tide
In the beginning…there was nothing but forests here. There were no people, no embankments, no fields. Just kada and bada, mud and mangrove. At high tide most of the land vanished under water. And everywhere you looked there were predators – tigers, crocodiles, sharks, leopards…This was a time when people were so desperate for the land that they were willing to sell themselves for a bigha or two.[1]

Sandeshkhali I is a community development block that forms an administrative division in Basirhat subdivision of North 24 Parganas district in the Indian state of West Bengal.

Geography

Nazat is located at 22°27′16″N 88°50′45″E / 22.454532°N 88.845834°E / 22.454532; 88.845834

Sandeshkhali I CD Block is bounded by Minakhan and Hasnabad CD Blocks in the north, Hingalganj CD Block in the east, Sandeshkhali II CD Block in the south and Bhangar II and Bhangar I CD Blocks in South 24 Parganas district in the west.[2]

Sandeshkhali I CD Block is part of the North Bidyadhari Plain, one of the three physiographic regions in the district located in the lower Ganges Delta. The area is full of marshes and salt water lakes. The Bidyadhari has a long course through the central part of the district.[3] The wide Dalma and Besti rivers flow through the area.

Sandeshkhali I CD Block has an area of 182.30 km2. It has 1 panchayat samity, 8 gram panchayats, 99 gram sansads (village councils), 30 mouzas and 30 inhabited villages. Nazat police station serves this block.[4] Headquarters of this CD Block is at Nazat.[5]

Gram panchayats of Sandeshkhali I block/ panchayat samiti are: Bayermari I, Kalinagar, Sarberia Agarhati, Bayermari II, Nazat I, Sehera Radhanagar, Hatgachhi and Nazat II.[6]

Sundarbans

The Sundarbans is a flat lowland susceptible to storm surges along the 260 km shoreline of the Bay of Bengal. The total expanse of Sundarbans is about 2.05 million hectares (8,000 square miles). Of this, only 0.42 million hectares (1,629 square miles or 10,43,000 acres) are under the reserve forests including about 0.19 million hectares covered by creeks and channels. The area is prone to natural calamities such as cyclones, thunderstorms with occasional hail and floods. There are more than 63,400 km of embankments but the floods caused by high tidal bores, often wash away much of the embankments, already weakened and broken by earlier cyclonic storms.[7]

In May 2009, the district was hit by high speed cyclone named Aila and subsequent rainfall which continued for two days. This created a disaster in 20 out of 22 blocks of the district. 10 out of 27 municipalities of the district were also severely affected.[7]

Six CD Blocks of North 24 Parganas are included in the Sundabans area – Hingalganj, Hasnabad, Sandeskhali I and II, Minakhan and Haora.[7] The south-eastern part of the district gradually merges into the Sunderbans.[8]

  Household industries (3.92%)
  Other Workers (36.49%)

In more than 30 percent of the villages in North 24 Parganas, agriculture or household industry is no longer the major source of livelihood for the main workers there. The CD Blocks in the district can be classified as belonging to three categories: border areas, Sundarbans area and other rural areas. The percentage of other workers in the other rural areas category is considerably higher than those in the border areas and Sundarbans area.[30]

Note: In the census records a person is considered a cultivator, if the person is engaged in cultivation/ supervision of land owned by self/government/institution. When a person who works on another person's land for wages in cash or kind or share, is regarded as an agricultural labourer. Household industry is defined as an industry conducted by one or more members of the family within the household or village, and one that does not qualify for registration as a factory under the Factories Act. Other workers are persons engaged in some economic activity other than cultivators, agricultural labourers and household workers. It includes factory, mining, plantation, transport and office workers, those engaged in business and commerce, teachers, entertainment artistes and so on.[31]

Power

The remote villages and hamlets situated in the area suffer from chronic shortage of energy due to non-availability of grid power. It is extremely difficult to extend high voltage transmission lines because of technical limitations in an area with inhospitable terrain and prohibitive cost. A scheme is being formulated to cover about 750,000 people in the difficult areas of Sundarbans with non-conventional energy power within the year 2012. The scheme covers Gosaba, Sagar, Pathar Pratima, Namkhana, Kultali, Hingalganj and Sandeshkhali.[33]

Agriculture

The North 24 Parganas district Human Development Report opines that in spite of agricultural productivity in North 24 Parganas district being rather impressive 81.84% of rural population suffered from shortage of food. With a high urbanisation of 54.3% in 2001, the land use pattern in the district is changing quite fast and the area under cultivation is declining. However, agriculture is still the major source of livelihood in the rural areas of the district.[34]

From 1977 on wards major land reforms took place in West Bengal. Land in excess of land ceiling was acquired and distributed amongst the peasants.[35] Following land reforms land ownership pattern has undergone transformation.

Micro-credit

Micro credit is serving as an effective tool of economic emancipation of women, empowering them to fight against many social evils and the age-old atrocities in the villages. JYDC an NGO, in collaboration with National Bank for Agriculture and Rural Development (NABARD) has established 1047 self-help groups with 12000 members spread over 24 villages (mouza). SHG members of Sandeshkhali raised Rs.40,000/-loan from Bank of Baroda to start a poultry farm.[37](31 March 2008, BDO, SDK-II)

In 2011, Sandeshkhali I CD Block had 1 block primary health centre and 2 primary health centres, with total 23 beds and 4 doctors (excluding private bodies). It had 35 family welfare subcentres. 1,668 patients were treated indoor and 83,016 patients were treated outdoor in the hospitals, health centres and subcentres of the CD Block.[36]

Ghoshpur Rural Hospital at Ghoshpur with 30 beds functions as the main medical facility in Sandeshkhali I CD Block. There are primary health centres at Agarbati (Hatgachia PHC with 10 beds) and Nazat (with 6 beds).[43]

Although in North 24 Parganas district groundwater is affected by arsenic contamination, tubewells in Sandeshkhali II block are arsenic safe according to Indian standard (50 µg/L) and in Sandeshkhali I block only 0.6% tubewells exceed 50 µg/L.(study conducted by JYDC an NGO). A lab was set up by JYDC in collaboration with UNICEF and government of West Bengal to monitor drinking water in the area. The probable reason may be, in Sandeshkhali, most of the tubewells are deep tubewells.[44] A study of iodine deficiency disorder amongst children found that prevalence of goitre amongst school children was very high at Sandeshkhali.

Four launches with doctors carrying medicines, sophisticated portable X-ray and echo-cardiograph machines, provided by the French author Dominique Lapierre move along the waterways of the Sundarbans to its furthest corners, associated with the esteemed NGO Southern Health Improvement Samity (SHIS) [45]
