Irrigation in Bangladesh


Our agriculture had been traditionally and heavily dependent on rainfall; our farmers, on old fashioned agricultural tools that are driven manually and on naturally grown seeds and seedlings. Not very long ago modern technology was introduced and many appliances for cultivation were mechanized or power driven. Improved seeds or high variety of crops were launched side by side with the old ones; considerably extensive land is now manured with chemical fertilizers and crops are protected from pests or insects attack by specially made pesticides or insecticides. Irrigation facilities have been installed as the corner stone of our agricultural production for steady and timely supply of needed water. The result of the factors is an attainment of near sufficiency in rice output apart from considerable increase in other agricultural products.


There has been our almost total dependency on monsoon. It is proverbially uncertain and uneven in distribution of rains. It blesses some parts of the country with 80% of rainfall particularly in the rainy season, condemns most parts to inadequacy of rain and some parts especially in northern Bangladesh is cursed with little or no rain. And the country suffers from much inadequacy of rainfall on mid-Nov. mid-April. Rainfall including monsoons’ vagaries are terrible in the breach of constancy and timeliness. Over and above, we are victims of other caprices of nature causing massive damage to our various seedbeds and crops at different times of their growth. Another serious handicap is the scarcity of land for cultivation because of over-population. In the early years of the nineteen eighties out of 35 million acres of land we had about 23 million for tilling. More than 21 million of the cultivable land were used for growing crops in the rainy season and the rest was not tilled for want of rain in winter. As a result about 7 million acres of land were utilized during Rabi season and the intensity of cropping was very low.

To solve these predicaments irrigation has been made pivotal in agriculture. Two ways were formed on the basis of ground water and surface water for irrigation: Groung water for tube well irrigation is made available especially in north western region. To have quick impact of investment of irrigation small scale and fast pay off programmers installation of hand tube-well (HTW), deep tube-well (DTW), Shallow tube-well (STW), and low level pump (PLP) were undertaken. Bangladesh Agricutuure Development corporation (BADC), the only public agency, has increased more than double of them over the years. Private participation both individual and in group has also considerable grown. Bangladesh water development Board (BWDB), another public agent, completed a number of small or medium irrigation projects like Karnafuli, Monu river projects and long term projects such as Teesta Barrage for irrigation, drainage flood control, etc. For the same objectives a number of projects are being implemented: FDR/98, Teesta Barrage projects ph-1 for rehabilitation of flood damage, salinity protection project in Najir-hat area, Narayanganj-Narshindi Fc irrigation project, Kurigram Fc & irrigation N. Unit and S unit, Sundai irrigation project, Matamuhuri irrigation project, Modhumati River’s dredging project and so on. (From BWDB project under RADP 2000-2001). Share of net cultivated was 11.15% in 1977 and extended to 48.31% in 1996, the reported farm holding area also expanded from 30.37% in 1977 to 64.17% in 1996, along with the rapid expansion of irrigation, the net fertilized area is more than double in the same period. Though our country is nearly sufficient in production of rice, the requirements for food sequrity during the natural disasters, for the annual increase of population and the balanced development of all parts of the country, provision for irrigation facilities is continuing.

Irrigation is concentrated in winter as then there is virtually no limit to land for cultivation. This season is free from floods, cyclones, storms and has enough sunshine for cultivation of boro rice including irri and wheat in particular. There is no need for protection from flooding or for drainage. The environment is controlled by irrigation and this is more suited for better utilization of applied nutrients. For that matter irrigation is not neglected for aman, the deep water product limited by topographical conditions. For it covers 16.2% of rice land. T-Aman is produced through irrigation by transplantation of seedlings. And aus rice variety called irri is also grown in plenty. Furthermore, irrigation has made possible the growing of Radi crops such as millets, patato, oil seeds, pulses, tobacco, flax, cotton, barley, etc. require temperate climate. It has, additionally, enabled inter-cropping of oilseeds; pulses, spices with sugarcane and cotton. It has facilitated efficient use of land and intensity of cropping. All this, no doubt, has boosted earnings of farmers.

Irrigation has been encountering a few problems and predicaments. The drying up of underground water in March 2003 in 12 upazillas of Mymenshingh due to lifting of water by deep wells, low lift power pumps and traditional pumps, threatened irrigation of boro irri paddy, caused acute scarcity of drinking water and made crack in the fields. Dried up also are most of the rivers, canals and marshes. Water supply in irrigation projects are neither satisfactory nor adequate. In Meghana Dhanagoda project area there was acute shortage of water as canals were not yet excavated or re-excavated in time. To avoid loss, farmers are watering their lands through pumps at a much greater cost. Farmers of Narayanganj – Narshindhi Agrani project area were unable to sow in March 2003, at about 41/2 thousand acres of cultivable land because some canals of block I had dried up and there was water logging in the project areas. These encounters are expected to exist in the project sites in many parts of the country. Another serious trouble is the erratic power supply all over the country. It has become a regular feature in many districts of siuth western zone. Load shedding and frequent power failure both of which continue for several hours aggravated much more the hampering of irrigation. For power supply has been far from satisfactory there for a long time. Apart from irrigation, husking of paddy and wheat crushing are impeded low voltage and irregular supply damaged, at least twelve motors in a few upazillas of Joypurhat in 2003 and adulterated diesel mabe a number of motors inoperative at Bhairab. And the malpractice’s of especially CBA employees of PDB made things worse.

The present crises (2003) in Rajbari of seedlings, irrigation and price hyke of diesel exemplified various predicaments of marginal and small farmers around the country. The recent price hyke of diesel, in particular, has increased the cost of transplanting of seedlings. The cost of ploughing an acre of land by power tiller which was 600/- to 700/- last year is increased to Tk. 1000 to 1100 now. Previously irrigation machine owners had to be paid 25% of crops, at present they are taking one third of them on the plea of increase of prices of diesel. Moreover, the cultivators have to buy per drum of diesel at Tk. 4500/-, though govt. fixed its price at Tk. 3800 so making things worse. In such circumstances the cost of production per acre including wages of labour for transplantation, weeding, reaping, prices of fertilizers and insecticides was estimated to be Tk. 10000 to 11000. In some other upazillas, namely, Austa Gram farmers were facing extreme difficulties for rise of diesel price. Now we can imagine what marginal profit the small farmers can make for the sale of 40 mds of paddy as one third of the produce is to be given to machine owners for irrigation out of the total 60 mds which is the normal yield in an acre of land. They could lessen much the cost if they can own agricultural implements, motors, tube, wells, etc. But owing them will be a dreaming for them.

Our agriculture has been essentially subsistence crops in character. The hard up farmers as they are compelled to sell their products, say rice, cannot wait long to get a fair price for it. Considering their plight and hardship, it is incumbent upon govt. to provide them HYV seeds, fertilizers and irrigation facilities free or at a nominal price or charge. There is a good progress in agriculture. All credit is given to non-human elements, neglecting the farmers, the pivots of the progress. Nothing can be so unjust and in human for us to leave them to their plight and hardship. It will be sheer exploitation of the helpless marginal farmers smarting under poverty and hardship. It will be down right ingratitude and barbarity because we own them greatly.
