“…Improper design of canal, poor management, insufficient freeboard etc are the main factors of the loss. This result is similar to Sayed (2010), who found 41%, 48% and 45% conveyance loss in earthen canal at Mithapukur, Manikganj sadar and Dhamrai respectively. Water loss in conveyance found 6.1 and 0.5 l s -1 per 100 m in FM and RM respectively.…”

An experiment was conducted at farmers' field aimed to evaluate the water saving technologies in Boro rice. The experiment involved three plots at 33 m, 65 m and 100 m distance from the water source. Each plot was divided into two parts to accommodate two management practices as research management (RM) and farmer's management (FM). RM comprised of plastic pipe water distribution system to reduce conveyance loss and alternate wetting and drying (AWD) method for field water management. FM comprised of earthen canal water distribution system and conventional irrigation method. BRRI dhan28 was cultivated with recommended agronomic practices. In RM, irrigation was applied when water level went 15 cm down below the ground surface where FM included conventional practice. Result showed that conveyance loss of water in earthen canal increased with increasing the distance from water source to field. Conveyance loss found 6.1 and 0.5 l s -1 per 100 m in earthen canal and plastic pipe distribution system, respectively. Plastic pipe distribution system successfully minimized 91.6% water loss that occurred in earthen canal. AWD practice alone saved 20.2% field water over conventional practice. Combination of AWD and plastic pipe had saved 42% water, Tk 2,270 ha -1 as electricity cost and Tk 2,947 ha -1 as irrigation cost over farmer's management. RM had higher yield than FM due to better performance of yield contributing parameters. Water productivity increased from 0.35 kg m -3 in FM to 0.65 kg m -3 in RM. Both the technologies in RM are environment friendly for reducing groundwater use in the irrigated ecosystem.

“…In Bangladesh, Sattar et al (2009) pointed out that a large amount of water is wasted in rice plots due to continuous ponding. Sayed (2010) emphasized the importance of command area development to improve irrigation efficiency, noting substantial transportation losses in earthen canals. Rashid (1991) discussed the uneven frequency distribution of water resources in Bangladesh and the growing significance of groundwater exploitation.…”

Pakistan being an agricultural-based economy, needs to pull-out of the problems related to the agriculture sector. Irrigation system of Pakistan has leads to various seepage losses from the canals. The canal seepage leads to various problems including salinity and the waterlogging, ultimately devastate the land and its agriculture use. This study explores the causes of the water loss before the canal lining and its impact on the agriculture productivity, along with the[1] socioeconomic impact of the canal lining on the farmers and relevant respondents. The targeted area of the study was the agricultural zone of Faisalabad region of Punjab, Pakistan. Simple random sampling technique were utilized to collect the sample of 140 respondents. An amalgam of quantitative and qualitative sampling is adopted by relaying on surveys, interviews, observations and analysis of data. A descriptive analysis is conducted to analyze the data by using percentage and frequency method. The results indicate that the 46.4% respondents have 17-25 minutes per Acer of time allocated for canal water turn followed by 32.9% with 16 minutes allocated for canal water turn. Majority of respondents (47.1%) reported that water quality is improved after lining. Sixty-five percent view that the lining has reduce water logging to some extent, only 13.6% reported it ineffective. The 50.7% of total are concerned to some extent for water resources depletion while 31% to great extent. Majority (45% of respondents) report that canal lining is useless in preventing crops from the pest attack. 50.7% report that any industry exploits the canal while 49.3% said no industry use it. Majority reported that government policies are available for farmers (65.7%). It is indicated that there is significant relation between the farmer’s age & education and the assessment of the socio-economic impact of canal lining. Higher income also leads to higher assessment of the socioeconomic impact of lining. Thus, most of the farmers support the canal lining except few favoring the Kacha Warabandi system. Findings favor the socioeconomic factor and their role in defining the farmers’ behavior. Yet the effective planning, reducing conflicts, improving allocation and distribution can be helpful increasing capacity of the croplands and the sustain the agriculture sector equitably.

“…The closest water source is a river which is at least 2 km away from the cultivable land. Therefore, traditional canal-based irrigation methods are inadequate as they can suffer from water seepage of about 40% [50]. Furthermore, manual AWD is not able to provide efficient water level control over this large area of irrigated land.…”

“…In traditional irrigation systems, water distribution is performed using earthen canals [50] due to their low initial cost. However, these canals result in poor distribution efficiency, less area coverage, and, in the long run, results in high maintenance costs.…”

“…The main factor causing this loss in the earthen canals is due to seepage loss. Studies have found that about 40% of the water is lost during the distribution time through the earthen canals [50]. The proposed automated AWD system using plastic pipes can overcome this conveyance loss, and help reduce the irrigation time, which in turn results in less energy (fuel or electricity) to operate the pumps.…”

Water, one of the most valuable resources, is underutilized in irrigated rice production. The yield of rice, a staple food across the world, is highly dependent on having proper irrigation systems. Alternate wetting and drying (AWD) is an effective irrigation method mainly used for irrigated rice production. However, unattended, manual, small-scale, and discrete implementations cannot achieve the maximum benefit of AWD. Automation of large-scale (over 1000 acres) implementation of AWD can be carried out using wide-area wireless sensor network (WSN). An automated AWD system requires three different WSNs: one for water level and environmental monitoring, one for monitoring of the irrigation system, and another for controlling the irrigation system. Integration of these three different WSNs requires proper dimensioning of the AWD edge elements (sensor and actuator nodes) to reduce the deployment cost and make it scalable. Besides field-level monitoring, the integration of external control parameters, such as real-time weather forecasts, plant physiological data, and input from farmers, can further enhance the performance of the automated AWD system. Internet of Things (IoT) can be used to interface the WSNs with external data sources. This research focuses on the dimensioning of the AWD system for the multilayer WSN integration and the required algorithms for the closed loop control of the irrigation system using IoT. Implementation of the AWD for 25,000 acres is shown as a possible use case. Plastic pipes are proposed as the means to transport and control proper distribution of water in the field, which significantly helps to reduce conveyance loss. This system utilizes 250 pumps, grouped into 10 clusters, to ensure equal water distribution amongst the users (field owners) in the wide area. The proposed automation algorithm handles the complexity of maintaining proper water pressure throughout the pipe network, scheduling the pump, and controlling the water outlets. Mathematical models are presented for proper dimensioning of the AWD. A low-power and long-range sensor node is developed due to the lack of cellular data coverage in rural areas, and its functionality is tested using an IoT platform for small-scale field trials.
