What is irrigation?

Irrigation is an artificial water supply for dry agricultural land by means of dams, barrages, channels or other devices.

OR

Irrigation may be defined as the artificial application of water to soil for the purpose of supplying moisture essential for plant growth.

Source of irrigation water:1.Surface water Gravity(canal) : 1,56,000 ha Low lift pump : 6,90,000 ha Traditional (Manual pumping): 3,63,000 ha2.Ground water DTW : 6,70,000 ha STW : 17,70,000 ha Hand tube well : 32,000 ha

Total Irrigation area : 36,90,000 ha of land

History of irrigation

In 1960, systematic irrigation stated in Bangladesh with the introduction of low lift pumps & DTWs by the government employer Akter Hamid Khan in Comilla district. STWs came into operation after 1980, Bangladesh has a land area of about 14.4 million hector of which 9.03 million ha(64%) are under cultivation. Irrigation is currently available to less than 50% of the land that can be irrigated in the Rabi season.

Irrigation devices commonly used in Bangladesh

1.Motorized pumps (DTW ,STW, turbine pump, low lift pump etc.)2.Manual pumps (don, swing basket , treadle pump, hand tube well etc.)

Irrigation project in Bangladesh

1.G.K project: In1954 area: 1,97,500ha, Ganga & Kobadak river2.Tipaimukh Dam: In 2009 area: 15,626 ha Barak river in Sylhet.3. Chandpur Irrigation Project: In 1973 to 1978 area: 57,000ha; Meghna

& Dakatia river4.Barrindra Irrigation Project(BIP): In 2007 area: 7,500acre; Bogra,

Rajshahi5. Teesta Barrage Project: In 1945 area:7,50,000ha; teesta river.

Methods of Irrigation commonly used in Bangladesh

1. Basin method: This method is widely used for rice irrigation.2. Border method: Used slightly sloping land.3. Furrow method: Suitable for line sown crops such as sugar cane, potato.4. Sprinkler method: Mostly suitable for undulated land & Hilly areas.

In Bangladesh about 94% of the irrigated land is under small and minor Irrigation.

According to recent survey water is being lifted in this country through(23march,2015, National Encyclopedia of Bangladesh)

DTWs : 26,704 nos. STWs : 4,69,226 nos. Low lift pumps : 56,829 nos. Manual pumps : 1,42,132 nos. Indigenous water lifting devices : 5,65,000 nos.

In Bangladesh, both shallow & deep tube wells are widely used.

The demand for irrigation water is increasing day by day & the cost is increasing accordingly. In present condition irrigation efficiency is only about 30%.

With proper utilization & improved management, 4 to 5 million hector of land can be irrigated easily by using the same number of irrigation devices instead of the present 3.12 million hector.
