Irrigation
is a blessing to agriculture of any country. It turns barren land into smiling
crops fields. It is irrigation that can ensure timely water supply to land. Irrigation
adds to agricultural prosperity and increases the yield per
acre. It also makes possible to grow improved varieties of crops. Irrigation
also leads to the growth of the meas of transport and communication and the
flourishing of internal and external trade. In Bangladesh, the problem of
irrigation is, however, regarded from a different angle of vision. Mr. R. G.
Casey, at one time a Governor of Bengal, aptly said, “ East Bengal suffer, not from scarcity
of water but from too much of it’ Thus the
problem here is one of the flood control, checking erosion and removing
water from the marshy lands. During the rainy season, devasting floods occur
and destroy standing crops. These floods can be resisted if high embankments
are constructed along the banks of the big rivers. Already the
Gumti bund in Comilla, the Karnafuli bund and the Meghna bund,
together with the coastal embankment along the Bay of Bengal in the southern
districts- Khulna, Bakerganj, Noakhali and Chittagong, have been constructed.
Secondly, in order to control floods, the beds of the existing rivers should be
made deep enough and the still must be removed from the mouths of rivers. For
this purpose dredging is essential.
Irrigation system |
Out ot 24 million acres of
cultivable land in Bangladesh only 6 lac acres are irrigated by various
traditional methods which are extremely back-dated, time-consuming and
inadequate. In recent years emphasis on irrigation by power pumps has been laid. So
far about 38000 power pumps have been introduced and near about 18 lakh acres of
land are said to have been brought under irrigation by the method. Some farmers
of our country are also using them. But they should use them on an extensive
scale so that plentiful underground water may be utilized for irrigation in dry
season. There are hundreds of tanks, canals and rivers in our country.
It is estimated that 13 million acres
additional land can be irrigated here by extensive drainage, construction of
diversion works and canals and pumping of surplus water. Still
Bangladesh has several irrigation schemes of which the Ganges-Kodak scheme is
the most important. It irrigates over 50 lac acres of land in Kushtia, Jessore
and Khulna districts. But in recent years the Farrakh problem has dealt a death
blow to this major irrigation scheme of Bangladesh. The Teesta Barrage project
also irrigates over 1 lakh acres of land in the districts of Dinajpur, Rangpur
and Bogra. To know more about 'Eyesight of Bangladesh'
