Krueng Baro Irrigation Area is one of the irrigation areas which is focused on increasing food crop productivity in Pidie District. To support the existence of the irrigation, of course, it must be supported by a well-organized irrigation system, so an effective irrigation network management system is needed through the O M program. O M activities require a truly real value or cost figure which is the result of the search for irrigation networks known as the real operation and maintenance demand value. The physical condition of the Krueng Baro Irrigation Network if viewed from the results of the irrigation network inventory still has many obstacles that hamper the fulfillment of rice water needs, including physical damage to buildings and irrigation channels. The evaluation of irrigation network performance is the first step in the preparation of the real operation and maintenance demand value, the rate of performance of the Krueng Baro Irrigation Area network is 68.06% (BWSSI, 2017) which falls into the less category and needs attention. This study aims to identify Irrigation Network O M activities and the real operation and maintenance demand value Krueng Baro irrigation. The research method is in the form of observations / field observations and documentation to obtain the existing conditions of irrigation networks which subsequently identify O M plans and preparation of the real operation and maintenance demand value. After the preparation of the real operation and maintenance demand value was obtained the output of the value of the real cost requirement in carrying out routine operations was only 0.53% (IDR 529,180,000.00), Routine Maintenance 6.52% (IDR 6,510,464,300.00), while for Periodic Maintenance is very large, namely 92.95% (IDR. 92,764,196,192.00) compared to the overall total cost (IDR. 99,803,840,492.00). In order to achieve the full O M Plan and the real operation and maintenance demand value Krueng Baro Irrigation Network due to the limited budgetary budget so is divided into a 5-year priority program plan reference to Minister of Public Works and Housing Regulation No. 12 / PRT / M / 2015 with the first year priority carried out on the main building which greatly influences performance and function of the irrigation system such as turnover of intake doors, olak ponds and upstream weir sediment excavation and some buildings and channels that have been destroyed and not functioning on the carrier channel.

Small Scale Irrigation

Sectoral economic growth data in Ethiopia show that the agriculture sector has the lowest growth, which is caused by frequent drought and inefficient technologies, among other factors. As a result, the productivities of land and labor, as well as the income of small-scale farm households, are very low, and rural areas have a relatively high poverty rate. A quasi-experiment was applied to understand the impact of using small-scale irrigation motor pumps on farmers’ livelihood improvement. Specifically, a survey was conducted in 2019 on a sample of 92 small-scale irrigation motor pump and canal irrigation users as the treatment and control groups. The weighted propensity score matching method was applied to eliminate initial differences and adjust sampling proportions across the groups. Based on the average treatment effect on the treated estimation results, we cannot state that the mean income difference in small-scale irrigation motor pump users and canal irrigation system users is different from zero. This indicates that countries with little capital to invest in large-scale irrigation projects can introduce household-level small-scale irrigation motor pumps to improve farmers’ incomes.

Some prominent Mesoamericanists long considered lowland central Veracruz to have been agriculturally unproductive prior to the Totonacs' construction of a canal-irrigation system at Zempoala during the Middle Postclassic period (A. D. 1200-1400). This evaluation reflects a long-standing negative predisposition toward tropical lowlands and a preoccupation with the significance of canal irrigation in the emergence of urban societies. However, an appreciation of mesoenvironments and their ecological interrelations has led to a reevaluation of agriculture in central Veracruz. In wetlands to the south of Zempoala, evidence of canals and planting platforms supporting maize cultivation by A. D. 500 demonstrates that people were intensively cultivating that mesoenvironment by the Classic period (A. D. 1-850). Moreover, vestiges of sloping-field terraces occur throughout some 1,000 km2 of piedmont west of those wetlands. Direct evidence for crops and a chronology are still lacking for these latter fields, but ethnohistorical data and plant ecology suggest cotton, maize, agave, and a Prehispanic origin.

AbstractThere is ample evidence that canal systems often fail to reach their design capacity. This study argues that inefficient allocation of water within canals is one cause. This study collects precise measures of farm-level water withdrawals using flow meters in a canal in Pakistan. These data reveal that farmers near the head of the canal get more canal water than farmers near the tail, even accounting for conveyance efficiency. The results suggest that improvements in canal water management would yield efficiency gains for the canal.

Abstract This paper proposes scenarios to achieve more crop per drop and irrigation for all in water-scarce irrigation systems, with a particular reference to India. It uses economic water productivity (EWP) and water cost curve for EWP as tools to reallocate irrigation consumptive water use (CWU) and identify economically viable cropping patterns. Assessed in the water-scarce Sina irrigation system in Maharashtra, India, the method shows that drought-tolerant annual crops such as fruits and/or fodder should be the preferred option in irrigated cropping patterns. Cropping patterns with orchard or fodder as permanent fixtures will provide sustainable income in low rainfall years. Orchards in combination with other crops will increase EWP and value of output in moderate to good rainfall years. Governments should create an enabling environment for conjunctive water use and allocation of CWU to achieve a gradual shift to high-value annual/perennial crops as permanent fixtures in cropping patterns.
