Preliminary Study

Abstract Unit Tamban is a fork system of lowland irrigation areas in Kapuas District. It has three primary canals, and each of them has a settling pond at the end. Most of the 3,506 ha planting area still apply once a year cropping patterns. A quick assessment based on field observations is carried out to determine the existing problems, including water management, water quality, and soil quality. The problem in the water management system is silting in the primary and secondary canals. The settling pond at the primary canal was no longer functioning, and it makes the silting worse because the water flow became uncontrolled. Water quality is measured with pH and TDS, the average pH at canal water was 4,22, and TDS was 71 mg/l. The soil type is mainly acid sulphate with pyritic materials, mostly 70 cm below the surface. Increasing cropping patterns twice a year requires improving the water circulations and increasing the soil pH higher than five. The problem in the secondary canal is expected to solve by changing the flow pattern from two way to 1-way flow is needed to avoid dead spots of water so that the leaching processes can work well.

Abstract The average rice productivity of the Rote Ndao Regency is still below the national rice productivity. The cropping pattern’s lack of management and limited water sources can only be planted once a year. This study aims to determine the availability and quality of surface water used for irrigation with the existing rice-corn-fallow cropping pattern. The research was carried out by measuring discharge in the field, surveying the types and cropping patterns, irrigation area research, surface water quality analysis, and hydrological analysis. The results showed that the need for irrigation water for agriculture in the study area with the current cropping pattern was 0.84 lt/second/ha. Therefore, the existing irrigation area of ±3,762.00 Ha requires a water discharge of ±3.159 m3/second. The availability of surface water in the Lobalain District is low, with a discharge of ±1.598 m3/second. Surface water quality shows the percentage of sodium (Na%) dominated by excellent to permissible class, and the sodium adsorption ratio (SAR) excellent. The existing resource of surface water could not support agricultural irrigation. Therefore, it is necessary to find an alternative water source such as groundwater.

Nowadays, ecological problems are being caused by economic aspects, and other hand economic issues are arising from ecological and environmental problems. Therefore, it is important to consider both social and economic factors, and take a basin approach to solving environmental problems. To find a relationship between economy and ecology, complex study of river basins is extremely important in establishing conditions for sustainable development in our country. This paper shows the results of applying DPSIR (Driver-Pressure-State-Impact-Response) analysis for Ulaanbaatar city, undertaken as part of a project on Integrated Water Management for the Selenge River Basin. The DPSIR analysis looks at the linkage between the economy and environment for the water quality and water resources of Ulaanbaatar. We used mDSS4 software to evaluate a range of management responses suggested by these issues and found that charging for pollution and measuring water use would have the largest overall impact on water quality and water resources respectively. The analysis was carried out for Ulaanbaatar, because it was identified as one of the key hotspot areas in the Selenge River Basin, which is the main river basin in Mongolia, in terms of both the economy and natural systems.DOI: http://dx.doi.org/10.5564/pmas.v0i4.43Proceedings of the Mongolian Academy of Sciences 2009 No 4 pp.22-31

Air, baik air tanah maupun air permukaan merupakan sumber kehidupan yang tidak dapat tergantikan oleh apa pun dan tanpa air, manusia, hewan dan tanaman tidak akan dapat hidup terutama sebagai air minum. Tetapi dalam pemanfaatannya, masih banyak yang tidak sesuai dengan peruntukannya ataupun mempergunakan sampai diluar batas, sehingga disatu sisi banyak yang terbuang dengan sia-sia tetapi dilain sisi banyak yang membutuhkan. Penggunaan air selama dasa warsa terakhir ini meningkat disebabkan oleh beberapa faktor, antara lain oleh kegiatan manusia yang semakin bervariasi, pertambahan jumlah penduduk yang meningkat, maka jumlah air untuk kebutuhan manusia juga meningkat dan hal ini berpengaruh terhadap kualitas air. Selain itu juga berpengaruh terhadap keterbatasan air dan kondisi alam. Untuk itu diperlukan suatu system pengelolaan air yang sangat baik dengan memperhatikan akan kondisi alam dan ketersediaan akan air sehingga tercapai suatu pengelolaan yang sesuai dengan tata kelola air. Kata kunci : air, pengelolaan air, lingkungan AbstractWater, both ground water and surface water is the source of life that can not be replaced by anything and without water, people, animals and plants will not be able to live.But in its utilization, there are still many who are not as intended or use to beyond the limit, so that on one hand many are wasted in vain, but on the other side of the many in need. Use of water during the last decade has increased due to several factors, among others,by human activities increasingly varied, the number of population increases, the amount of water for human needs has also increased and this contributes to water quality. It also affects the limitations of water and natural conditions. It required a water management system is very good with attention to natural condition sand the availability of water in order to reach an appropriate management of the water governance and the availability of clean wateris needed.  Keywords: water, water management, environment

Nowadays there are too many grave disadvantages in water management system of Russian Federation, the USA and many European and Asian countries. It is caused by the peculiarities of the water bodies of the countries, whose exploitation is necessary for the full implementation of this industry. The article presents this problem in comparison with the experience of countries with developed economy, industry problems, coupled with the system of rationing allowable discharges, control and collection of payments, which is extremely important for ensuring water quality and is a basic tool for rational and sustainable water use.

Current Water

The current state of surface water quality is stable, but it is characterized by a number of problems that collectively call into question the effectiveness of the current water management system in the country. Over a long period of time, the volume of pollutants entering the uncontrolled, mainly diffuse, runoff to water bodies determines the unsatisfactory quality of natural waters and the poor environmental condition of water bodies. This is a consequence of the imperfection of the current water management system.

Abstract Determining the cropping pattern and schedule according to the availability and requirement of irrigation water is important in an irrigation command area. Supplying irrigation water in the Krueng Jreu Irrigation Area is still less effective in the dry season, so it is necessary to review the existing cropping pattern and schedule in the irrigation area by considering the K factor. To achieve optimal irrigation networks operation, simulation of cropping patterns and schedules based on the K factor was conducted. Optimal cropping patterns and schedules were determined by the highest frequency of the half-month K factor greater than 0.75. The best cropping pattern and schedule for Krueng Jreu Irrigation Area was rice-rice-soybean cropping pattern with first planting season started in mid-July, second planting season in mid-November and third planting season in mid-March. The results achieved the best frequency of K factor > 0.75 as many as 15 times, K factor in the range of 0.50 - 0.75 as many as 3 times, and K factor < 0.25 as many as 4 times. The application of the selected cropping pattern and schedule was done by allocating water into three groups in case of the K factor < 0.75, namely Group I (Menara and Krueng Aceh Extension secondary canal), Group II (Krueng Jreu Kiri secondary canal) and Group III (Kayee, Lamkrah, and Inong secondary canal).
