Exec ut iv e Sum m ary The major aim of this study is to assess the impact of Information and Communication Technology (ICT) application on groundwater resources management in Bangladesh. It is a research based study based on pilot areas through selecting a small number of deep tubewells. The study covers different areas of interest, which are the following: (i) Physical and policy context of ICT application in GW management, (ii) Compatibility of technology, (iii) Cost and benefit, (iv) Water delivery services, (v) Impact on water resources management (WRM), (vi) Synergy across water energy and food, and (vii) Scope for adoption and expansion in the region.The study has been conducted through (i) Requirement analysis (ii) Review of literature and information (iii) Reconnaissance field visit and case study sites selection (iv) Development of questionnaires and checklists (v) Initial stakeholders consultation workshop (vi) Field data collection through FGD and KII (vii) Data entry, processing and analysis, and, (viii) Preparation of comprehensive case study report/draft final report. Eight DTWs and one LLP (those running with ICT based prepaid meter system) have been selected in the case study sites on the basis of practicing the Information and Communication Technology (ICT). Two private DTWs, which are operated by electricity but without prepaid meter, have also been selected to make a comparison. These DTWs have been selected in three districts (Rajshahi, Rangpur and Dinajpur) according to the soil texture and AEZ (Level Barind tract and High Barind Tract). Field surveys were carried out in the selected upazilas to assess the impact of ICT on groundwater management. Key Informant Interviewers (KII) and Focus group discussions (FGD) were made for collecting necessary data and information. There were 9 to 11 participants in each FGD. Average age of the farmers who participated was 34 years and there were a mixture of male and female participants. Total twenty KIIs were conducted in the study areas, among which twelve KIIs were with farmers and eight KIIs were with the pump managers. Eight FGDs were conducted with the irrigation farmers and beneficiaries for collection of socio-economic information. Besides, a group discussion (GD) was held with the concern personnel’s of BMDA and BADC for better understanding of the overall scenario. It was observed from the field visit that before introducing the smart card based prepaid meter, the cropping pattern of the study area was mainly Kharif-2, and Rabi. After implementation of ICT based prepaid meter, cropping pattern turned to Kharif-1, Kharif-2 and Rabi. Command area and irrigated area before introducing ICT based prepaid meter was about 50 acres and 42 acres respectively. But after the introduction of ICT based prepaid meter, the command area and irrigated area increased to about 75 acres and 71 acres respectively. When water was normally distributed through the earthen canal system the irrigation efficiency was 84%. After introducing buried system irrigation efficiency increased to about 95%. This indicates that irrigation efficiency has increased due to change in water delivery pattern. Also, the irrigation cost has decreased because of the installation of ICT based prepaid meter.
In ICT based prepaid metering system irrigation cost per acre of agriculture land is about 2100 taka where as it was 3000 taka per acre when there was no metering system. Water demand by farmers has decreased for the installation of ICT based prepaid meter. Before installation of ICT based prepaid meter the average pumping hour was 30 /acre during the Boro season. But after installation of ICT based prepaid meter the average pumping hour has reduced to around 21hr/acre for the same Boro season. After introduction of ICT, the pumping hour has been reduced up to 30% and the electric bill up to 12%. At present farmers are very cautious about the optimum use of water in their ďŹ eld. As a result, minimum energy is used and maximum purpose is being achieved which is ultimately providing the sustainable use of energy. There is a wide scope of expansion of Barind model in other regions of the country. BADC has already been used smart card based prepaid meter for the irrigation purposes.. Bangladesh Water Development Board (BWDB) is going to introduce ICT on surface water management like Muhuri Irrigation Project (MIP). BWDB has a scope to apply the same on Ganges Kobadak Irrigation Project (GKIP), Teesta Barrage Project (TBP) and so on. Dhaka Water Supply and Sewerage Authority (DWASA) can apply the smart card based prepaid meter in drinking water purposes in near
future.

decided to collect substantial numbers of pre-paid meter/smart card from the SANAKOSH ASSOCIATES. Initially 500 pre-paid meter/smart cardswere issuedin a pilot project of BMDA. It was observed that farmers were getting irrigation water properly and at a comparatively less cost using this technology. Command area was also found to increase and 100% irrigation charge could be realized. BMDA then decided to collect more meters for all

It is a transparent system both for farmers and owners of the pumps.
Irrigation charge payment by farmers and services providing by BMDA are being ensured on mutual interactive basis.
The need based irrigation ensures optimum water use resulting minimum irrigation cost.
Excess ground water lifting is being controlled automatically which ultimately save energy consumption etc.

Farmers can establish their rights in terms of water use. They can get water at any time in any amount.
In case of irrigation smart card based prepaid metering system; farmers have to pay 2100 BDT/acre where as they have to pay 3000 BDT/acre in case of having no prepaid meter system(figure 4.11).
Smart card prepaid meter is very easy to use and operate. Even an illiterate farmer can use it easily.

Water De livery Service and Its Impact on WRM
5.1 Wa t er d el ivery syst em before u sin g I CT Primarily, it is irrigation that is needed for crop production. Proper water distribution system and its efficient management play very important roles in the command area development of any irrigation project. In Bangladesh, BADC first introduced DTWs in the northern part of Bangladesh. After that, BMDA developed low cost channel for the improvement of water distribution system in 1980s. At the initial stage, before using ICT based prepaid meter water was distributed through earthen canals. The conveyance efficiency of traditional earthen channel is 50-55% and the rate of water loss was 40-45% (BARI, 2007) during distribution. Water loss through seepage and percolation appears as additional loss in case of earthen canal when any cracks occurred on them. As a result, operational cost of earthen
Figure 5.1: Earthen canal irrigation system in Bangladesh
canals appeared as a burden to the farmers unless the command area was large enough.
5.2 Wate r d e liv e r y s ys t e m a f t e r usi n g IC T To reduce huge water loss, BMDA has developed the buried pipe distribution systems to reduce water loss. Generally in DTW of 1.5 to 2 cusec capacity the present command area is very small (22 to 40 acres) with conventional earthen canal system. This can be increased from 60 to 120 acres by installation of buried pipe irrigation system and can reduce the cost of irrigation. At present the buried irrigation system is expanded by BMDA and BADC (figure 5.2) in the DTW system for increasing the command area and reducing the cost of irrigation for crop production. They have also developed DTW operation by using smart card based prepaid meters with minimum irrigation charge on hour basis. After the introduction of smart card, Figure 5.2: Buried pipe irrigation system in Bangladesh command area has also been increased because of limited withdrawal of ground water. At present, farmers are very much alert about the use of excess water in their fields. On the other hand, farmers can irrigate their field anytime as per their need with the use of smart cards.

5.5.3 Mechanism of early warning system for ICT use in GWM At the time of irrigation using smart cards, the prepaid meter that houses the smart card always shows the reading of balance. As a result, the farmers always remain cautious about the balance. All of them have a tendency to save their money hence they do not waste any water.

of crops. Grain crops reveal their need for water by wilting

Research Institute and Bangladesh Agricultural Research
observations made of the moisture status of the soil. The
Institute are mentioned here:
Rice For rice a good yield can be obtained if the soil is in saturated condition from the time of transplanting. The number of tillers increases sufficiently if the field is in saturated condition up to 30 to 45 days after transplanting. The yield of rice is not hampered if the field remains dry for 3 days after disappearing of standing water in between each irrigation. Water requirements of rice are maximum at booting and flowering stages. During this period sufficient water should be maintained in the plot to get a good yield. For rice a single excessive irrigation should be avoided. Instead, frequent small irrigation is preferable. The depth of water in each irrigation should be 5 to 7 cm. The frequency of irrigation can be determined by dividing the depth of irrigation by the water to be depleted from the soil per day. Supplemental irrigation is beneficial for higher yields of rice, especially if there is drought at the critical growth stages of Aus and T Aman. Generally, around 60 mm water helps increase the yields of T Aman. Supplemental irrigation for T Aman is possible through rainwater harvesting, artificial irrigation facilities are not available). Adequate water (up to 60 mm) for T. Aman can be harvested if a ditch having an area equivalent to 5% of the planted area with 2 m depth is constructed at one corner. Aus paddy can also be cultivated on time if supplementary irrigation can be provided. This will also help in timely planting of Aman.
Wheat For obtaining a higher yield generally 2 to 3 irrigations are required for wheat. But the requirement varies from place to place due to variations in weather conditions and soil types. The first irrigation needs to be applied after 17 to 21 days of sowing. This irrigation may be delayed if there is sufficient moisture in the soil. Irrigation is needed at heading and grain formation stages. The second irrigation should be applied after 40 to 45 days and the third irrigation after 70 to 75 days of sowing. The depth of water in each irrigation should be 6 to 8 cm.
Potato Irrigation is important to obtain high yield of potato. The number of potatoes per plant is reduced if moisture stress occurs at the early stage. The grain size becomes smaller and irregular if moisture stress persists at the later stage. The first irrigation should be applied within 20 to 25 days of sowing and the second and third within 40 to 45 and 60 to 65 days, respectively, after sowing. In water shortage areas, if only one irrigation has to be applied, it should be within 20 to 25 days of sowing.
IMPACT OF ICT IN GROUNDWATER MANAGEMENT IN BANGLADESH
03
Maize Generally 4-5 irrigations are required for maize. The time of first, second, third and fourth irrigations are to be applied at 15 to 20, 30 to 35, 60 to 70, and 85 to 95 days after sowing respectively. The depth of water in each irrigation should be 6 to 8 cm at the initial stage and 8 to 10 cm at the later stage. Standing water must be removed at the flowering and grain filling stages.
Mustard The yield increases if irrigation is applied properly and timely. In most cases, the expected yield is obtained with 2 irrigations, but the range may be 1 to 3 depending on the variety and location. Irrigations should be applied after 25 to 30 days and 50 to 55 days of sowing. If the moisture content of the soil is less at the germination stage, light irrigation after 10 to 15 days of sowing may be helpful.
Onion Frequent small irrigations are preferable for better yield of onion. One or two irrigations should be applied after transplanting of seedlings. Then 4 to 5 light irrigations are required during the entire growing season at an interval of 10 to 15 days. The depth of irrigation should preferably be 2 to 3 cm at the early stage and 3 to 4 cm at the later stage. Standing water in the field is harmful for onion.
Tomato In Rabi season the yield of tomato increases 2-3 times if properly irrigated. Initially irrigation is required daily after transplanting the seedlings. The intervals may then be gradually increased from 3 to 4 days to 10 to 12 days. The irrigation depth needs to be 3 to 4 cm at initial stages and 4 to 6 cm at later stages.

where improvement is evident are listed below:
Impro vem ent o f water s u p p ly s ystem Each farmer has his own smart card so by using it they can get water any time as per requirement. In the past, the managers and land lords controlled the overall irrigation, for which water right could not be achieved most of the time.
IMPACT OF ICT IN GROUNDWATER MANAGEMENT IN BANGLADESH
03
R e d uce I r r i g ati o n a nd p ro d u c tion Cost As advance payment is required for getting water so everyone will try not to lose even a drop of water. This will minimize the total irrigation cost. As consequence to this, production cost will also be decreased. Irrigation cost with no metering system is about 3000 tk/acre where as it is about 2100 tk/acre for the use of smart card based metering system.
In crea si n g Co mma nd i ng A rea Due to economic use of water the commanding area can be increased through the use of same irrigation equipment. Before using the smart card based prepaid meter commanding area of each DTW was about 50 acre which has increased up to 75 acre after using ICT i.e. increase around 75%.
No sco pe o f p end i ng i r r i g ati o n charg e In the smart card system, all charges have to be paid before any irrigation. This prepaid system will be realized automatically and there will be no scope of irrigation charge to remain pending.
Lack o f Mi s ma na g ement There will be no scope of cheating the farmers by any operator or middlemen. Farmers will get their total water for the money they paid for buying their cards. There is also no chance of cards being stolen, as every card contains its owner’s picture and no card can be used outside of its specific location.
Meter Te m p er i ng There is no scope of tempering the meter. Any tempering or tempering attempt can be easily identified from the meter, as the meters are being monitored centrally by software.
R e a l Jud gm e nt Real judgment of the farmers as well as of the authority is possible by using smart card based prepaid meters. Farmers can get information at regular interval, how much money is available in his card and how many times can he get water can be discerned by themselves.
Ea sy to use Smart card is a very recent technology and is easy in operation and even a non-literate farmer can use it easily.

9.2 Sugg e s tion s Based on findings of the study, the following suggestions are made: Groundwater is one of the precious elements of nature. Application of ICT on groundwater management was first introduced by BMDA in 2005 in 16 districts of the north-western region of Bangladesh. There is a wide scope of expansion of Barind Model in other regions of the country. Some technical problems are found from the field survey; which are, disappearance of the recharged amount from user’s (farmer) account, which could never been compensated. BMDA authority should take necessary steps to monitor such technical problems for the betterment of the entire process. Radius of influence of each DTW is around 2500 ft, but the extension of buried pipe is up to 1800 ft. As a result, water when distributed some loss of water takes place due to seepage and percolation. So, BMDA authority should extend the underground buried pipe system in future. This will increase the overall efficiency of the delivery system. Shallow tubewells (STW) operation should be restricted in the command areas of Deep tubewells.
