Abstract Increasing of demand for water, allocation of limited water resources, climatic variability, degradation of water in the environment and developing of policies for sustainable water use are issues of increasing concern in the Kontsa irrigation project. This study aimed at assessing the effects of selected irrigation methods on water demand and allocation among farmers in Kontsa irrigation project. The study employed both primary and secondary data. The primary data were collected by interviewing 80 farmers, key informant interviews and observation of the project area while secondary data were collected from different agencies of Ethiopia. For this study Water Evaluation and Planning (WEAP) model was used to model the current situation of irrigation water demand and also to create scenario for future irrigation water demand. The model was set up for a current account year in 2015 and last year of scenarios in 2040 based on the available data. Then the irrigation water demand of the project area was modeled while giving consideration for existing and planned developments in the area. The result from the current situation of irrigation water demand indicated that the demand was satisfied fully and the unmet demand under the base year (2015) was zero. Additionally, irrigation expansion scenario was created and the result of this scenario indicates the increment of irrigation water demand as compared to the base year and the reference scenario. The study also revealed that furrow irrigation and plastic buckets were the main irrigation techniques employed by farmers in the study area.

The Cubo Trienggadeng Irrigation scheme has a potential area of 1,545 Ha while the functional area is 1,090 Ha. Based on the Irrigation Network scheme, Cubo Trienggadeng Irrigation Area consists of 3 (three) zones: Zone I, Zone II and Zone III. In Zone III of the Cubo Trienggadeng Irrigation Area which is the latest area receiving water from the Cubo Trienggadeng Weir often occurs in water shortages especially during the Gadu planting season (second planting season). Embung Paya Sepat is the reservoar found in Zone III D.I. Cubo Trienggadeng that is not being fully optimized in use. This study aims to optimize the utilization of Paya Sepat Reservoar so that it can meet irrigation water demand in Zone III D.I Cubo Trienggadeng by using the Water Balance method. This reservoar does not have a channel that supplies inflow discharge, so rainwater harvesting becomes a parameter in analyzing the supply of water to the reservoar. The optimization technique used uses a non-linear program using the Solver facility in Microsoft Excel software. Based on the results of the calculation of irrigation water requirements for an area of 204.50 Ha in the Gadu planting season, the maximum volume of irrigation water demand is 40,461,55 m3 at first periode in June, from the results of the optimization using the Maximize Release method, the results show that the water reservoar in Paya Sepat Reservoar can meet the water requirements in the Gadu planting season with an average reliability of 100%.. Therefore it is necessary to regulate the release of irrigation water that is well regulated and coordinated between the reservoar management and water users/farmers.

Java is the most populous island with the largest percentage of rice fields in Indonesia. However, rice fields in Java Island often experience water shortages, so an analysis of the potential water availability for irrigation in Java is required. This research aims to analyze water's potential to meet irrigation water needs in each catchment area in Java. In this research, the potential for irrigation water in Java is calculated based on the balance of water balance between water availability and DMI and Irrigation water needs. This research is divided into two parts: (1) analysis of water availability using the WFLOW hydrological simulation; and (2) water demand analysis based on population statistical data. Based on this research, it can be concluded that the water balance between water resources and irrigation water needs in Java is still in the surplus category, even though there are deficits in several catchment areas (WS): in the Kepulauan Seribu, Wiso Gelis, and Welang Rejoso WS. WS with the most water availability is generally located in wide (WS) areas, while several WS with abundant water needs is generally located in WS with the densest population. According to The Central Bureau of Statistics (BPS), the agricultural area in Java has decreased by an average of 20 thousand hectares per year, so that the demand for irrigation water on the island of Java will also decrease. Consequently, the excess water potential in Java Island needs to be allocated to meet the needs of DMI, which are increasing every year. In addition, the results also show that the development of irrigation areas in the future should be focused on large (WS) areas that have the potential for significant amounts of irrigation water.

ABSTRACT Sugarcane is both an important crop for the Brazilian Northeast economy, which faces severe water scarcity, and a water-intensive crop. Thus, it is important to develop irrigation strategies to reduce irrigation water demand in the region. This study aims to determine the sugarcane planting date that results in the maximum rainwater availability to the crop in the growing cycle. The crop effective precipitation was estimated from a soil water balance performed during three planting cycles of sugarcane, cultivar ‘RB 92579’. The crop was planted under subsurface drip irrigation in five months: October, November, December, January, and February, corresponding to the dry season period of the region. The experiment was conducted at the Açúcar e Álcool Coruripe Mill, located in the Coruripe municipality, State of Alagoas, Brazil, during the years 2012 to 2016. For all planting dates and growing cycles studied, the average effective rainy precipitation was equal to 30% of the total rainfall under irrigated conditions and 54.5% without considering the irrigation component in the soil water balance. November was the planting date that resulted in the minimum irrigation depth for the sugarcane growing cycle, with the potential irrigation water saving ranging from 5 to 129 mm.

Air tanah merupakan salah satu sumber daya air yang dapat digunakan untuk memenuhi kebutuhan irigasi. Dengan keterbatasan ketersediaan air, maka diupayakan dengan memanfaatkan air tanah dengan menggunakan sumur pompa. Penggunaan sumur pompa belum maksimal dalam memenuhi kebutuhan air irigasi maka diperlukan penelitian lebih lanjut. Tujuan dari penelitian ini adalah : (1) mengetahui teknis penggunaan sumber daya air tanah untuk irigasi menggunakan sumur pompa, dan (2) menganalisis kemampuan sumur pompa pada subak sampel di Kabupaten Jembrana terhadap kebutuhan air irigasi. Penelitian ini menggunakan analisis deskriptif kuantitatif melalui metode survey. Data ini diperoleh  menggunakan data primer dan sekunder. Data debit tersedia diperoleh melalui metode survei  langsung ke lapangan dan perhitungan kebutuhan air irigasi dilakukan dengan bantuan software CROPWAT 8.0. Berdasarkan analisis neraca air irigasi dari selisih antara kebutuhan air irigasi dengan ketersediaan air irigasi terhadap 3 sampel subak, diperoleh hasil pada Subak Sari Merta terjadi kekurangan air pada selama 2 periode yaitu periode Juni I sebesar 171.900  l/hari, Januari I 149.700 l/hari,  pada Subak Brawantangi terjadi kekurangan air sebanyak 4 periode yaitu periode Agustus  I sebesar 123.900 l/hari, Agustus II 99.200 l/hari, Maret I 98.000 l/hari, Maret II 78.200, dan pada Subak Tegal Badeng terjadi kekurangan air sebanyak 8 periode yaitu periode Juni II sebesar 64.600 l/hari, Juni III 178.500 l/hari, Agustus III 35.600 l/hari, September I 35.100 l/hari, September II 38.400 l/hari, September III 32.900 l/hari, November I 48.400 l/hari, November III 149.700 l/hari. Defisit air terjadi karena pada periode bulan tersebut dilakukan pengolahan tanah sehingga kebutuhan air irigasi cenderung tinggi. Untuk dapat memenuhi kebutuhan air irigasi yang diperlukan untuk pengolahan tanah, pada 3 sampel subak dilakukan sistem giliran memakai air irigasi supaya aktifitas pertanian dapat berjalan baik. The Ground water is one of water resources that can be used to fullfill the needs of irrigation. With the limited availability of water, it is attempted by utilizing ground water using pump wells. The use of pump wells has not been maximal in fulfilling the irrigation water requirement so further research is needed. The objectives of this research are: (1) To know the technical use of groundwater resources for irrigation using pump wells, and (2) to analyze the ability of pump wells in subak samples in Jembrana Regency to irrigation water needs. This research uses descriptive analysis through survey method, taking data using primary and secondary data. Available discharge analysis is obtained through direct survey method of spaciousness and analysis of irrigation water needs carried out with the help of CROPWAT 8.0 software. Based on the irrigation water balance analysis, there is a reduction between the irrigation water demand and the availability of irrigation water to 3 subak samples. In Subak Sari Merta it is known that there is water shortage 2 periods that is the period of June I equal to 171.900 l / day, January I 149.700 l / day. Subak Brawantangi is known that there is water shortage as much as 4 periods that is the period of August I equal to 123.900 l / day , August II 99.200 l / day, March I 98,200 l / day, March II 78.200 l / day. Subak Tegal Badeng is known that there is water shortage for 8 periods that is June II period is 64.000 l / day, June III 178.500 l / day, August III 35.600, September I 35.100 l/day, September II 38.400 l/day, September III 32.900 l/ day, November I 48,400 l / day, November III 149.700 l / day. Water deficit occurs because in the period of the month is done so that the processing of irrigation water needs tend to be high. To be able to meet the needs of irrigation water needed for the processing of the soil, the Subak Sari is done by the turn system using irrigation water so that agricultural activities can run well.
