Worldwide, water scarcity threatens delivery of water to urban centers. Increasing water use efficiency (WUE) is often recommended to reduce water demand, especially in water-scarce areas. In this paper, agricultural water use efficiency (AWUE) is examined using the super-efficient data envelopment analysis (DEA) approach in Xi'an in Northwest China at a temporal and spatial level. The grey systems analysis technique was then adopted to identify the factors that influenced the efficiency differentials under the shortage of water resources. From the perspective of temporal scales, the AWUE increased year by year during 2004–2012, and the highest (2.05) was obtained in 2009. Additionally, the AWUE was the best in the urban area at the spatial scale. Moreover, the key influencing factors of the AWUE are the financial situations and agricultural water-saving technology. Finally, we identified several knowledge gaps and proposed water-saving strategies for increasing AWUE and reducing its water demand by: (1) improving irrigation practices (timing and amounts) based on compatible water-saving techniques; (2) maximizing regional WUE by managing water resources and allocation at regional scales as well as enhancing coordination among Chinese water governance institutes.

Industrial Water Demand

The Yangtze River Economic Delta (YRED) faces inequality in water use in large proportions due to rapid industrialization. This study adopted the Gini coefficient and Global Moran’s index to calculate inequality, its spatial spread and water use efficiency of cities in the YRED and categorized them into types based on the spatial spread of inequality. In general, inequality is reducing, but water use efficiency is poor. Inequality was rated 0–1; zero being the highest equality while 1 indicates the highest inequality. There is relatively high inequality (0.4–0.5) in Shanghai, Suzhou and Hefei. Most cities (20), however, showed equality (below 0.2). Nine (9) cities showed relative equality (0.2–0.3), while Wuxi, Bengbu and Zhenjiang were neutral (0.3–0.4). No city scored above 0.5. Water use efficiency in the majority of cities was poor. Only 11 out of 35 cities scored more than 50% efficiency. Poor irrigation, income and industrial water demand are the factors driving inefficiency and inequality. The categorization of cities into groups produced nine city types according to the spatial disposition of inequality. A combined effort to formulate policies targeting improved water use efficiency, reduced industrial consumption and improved irrigation, tailored towards the specific situation of each city type, would eliminate inequality.

Water Metering

The Sultanate of Oman is experiencing increased pressure on its groundwater resources. This is mainly due to agricultural enterprises, which consume about 92 % of national water resources, as well as an upsurge in industrial, commercial and domestic water use. The ever-growing population, diversification of economic activities and the ensuing rise in national prosperity have meant an increasing demand for water. This has resulted in a marked depletion of groundwater supplies, intrusion of seawater, and deterioration of ground water quality in the case of the Al Batinah region. A scientific and effective water demand management strategy for the Sultanate is therefore needed. Accordingly, the Ministry of Regional Municipalities, Environment and Water Resources (MRMEWR) have conducted several studies related to water demand management in the agricultural, industrial and domestic sectors. One of these studies was the Water Metering Pilot Project (WMPP), initiated in 1994 with the objective of evaluating patterns of water use on a number of randomly selected farms in the southern Al-Batinah. The results obtained over a period of seven years confirm that water metering alone does not help reduce the quantity pumped. These findings have encouraged other advanced studies on water demand management in industrial, commercial, domestic and agriculture sectors in different areas of the Sultanate.

The countries of the Middle East are characterized by large temporal and spatial variations in precipitation and with limited surface and groundwater resources. The rapid growth and development in the region have led to mounting pressures on scarce resources to satisfy water demands. The dwindling availability of water to meet development needs has become a significant regional issue, especially as a number of countries are facing serious water deficit. Syria is becoming progressively shorter of water as future demand is coming close to or even surpassing available resources. Syria had a population of 18 million in 2002, and its total renewable water resources (TRWR) is estimated around 16 × 109 m3 per year. In other words, the per capita TRWR is less than the water scarcity index (1,000 m3 per person per year) which will make the country experience chronic stress that will hinder its economic development and entail serious degradation. Unfortunately, if water demand at current prices continues to increase in the same way, Syria will experience an alarming deficit between the available resources and the potential needs in the near future. In Syria, until fairly recently, emphasis has been placed on the supply side of water development. Demand management and improvement of patterns of water use has received less attention. The aim was always to augment the national water budget with new water. The most popular way of achieving this aim was to control surface flows by building new dams and creating multi-purpose reservoirs (there are now around 160 dams in Syria with a total capacity of 14 × 109 m3). Irrigation schemes were also built and agricultural activities were expanded greatly to achieve self-sufficiency in essential food products and food security. However, this is no longer achievable with the limited water resources available; water demand is rapidly increasing and easily mobilizable resources have already been exploited. The objective of this paper is to think of different possible ways to manage water demand in the agricultural sector of Syria. It mainly involves two main management options: taxation as a centralized option and water markets as a decentralized one. While water demand management refers to improving both productive and allocative efficiency of water use, this paper focuses on two allocative measures (taxation and water markets) and does not thoroughly cover productive measures such as rehabilitation and upgrading of irrigation schemes or improving operation. However, the paper does not attempt to settle the question for or against each option but tries to find some elements to determine under which conditions the option can lead to expected outcomes taking into account the history of management and the local conditions in Syria: political, social and economical. The paper also looks at other alternatives such as cooperative action and lifting subsidies and argues their possible association to the main management options that may help in reducing the difficulties of implementation.

Salah satu program penting dalam intensifikasi budidaya padi adalah pengelolaan air irigasi yang efisien. Pada subak di Bali pelaksanaan jadual tanam biasanya dilakukan secara serenpak sehingga terjadi puncak kebutuhan air yang tinggi. Akibatnya sangat berisiko terhadap kekurangan atau kelebihan air irigasai pada subak tersebut. Kondisi demikian menyebabkan efisiensi penggunaan air irigasi pada subak menjadi rendah. Salah satu solusi untuk meingkatkan efisiensi penggunaan air irigasi tersebut adalah dengan melakukan jadual tanam tidak serenpak yang pada subak dikenal dengan istilah nyorog. Dengan demikian perlu dikaji besarnya peningkatan efisiensi penggunaan air irigasi jika jadual tanam dilakukan secara nyorog Berdasarkan data yang telah dikompilasi diperoleh efisiensi penggunaan air irigasi yang dilakukan saat ini sebesar 76,52%. Saat ini pada obyek penelitian jadual tanam dibagi menjadi dua kelompok dengan beda jadual tanam antar kelompok tersebut sekitar satu bulan, dengan awal jadual tanam mulai Pebruari I.  Jika dilakukan jadual tanam secara serempak pada Pebruari II diperoleh efisiensi penggunaan air irigasi sebesar 69,05%.  Jika jadual tanam dilakukan secara nyorog dengan membagi subak menjadi empat kelompok dan setiap kelompok perbedaan jadual tanam sekitar setengah bulan serta awal jadual tanam pada Bulan Pebruari I maka diperoleh efisiensi penggunaan air irigasinya 86,52%.  Dengan demikian jadual tanam secara nyorog dapat meningkatkan efisiensi penggunaan air irigasi dari 69,05% menjadi 86,52%.    One important program in the intensification of rice cultivation is efficient irrigation water management. In subak in Bali the planting schedule is usually carried out simultaneously so that there is a high peak of water demand. As a result, it is very risky for irrigation water shortages or excess in the subak. Such conditions cause the efficiency of the use of irrigation water in subak to be low. One solution to improve the efficiency of the use of irrigation water is by not planting simultaneously which are known as nyorog in subak. Thus, it is necessary to assess the magnitude of the increase in the efficiency of the use of irrigation water if the planting schedule is carried out in a systematic manner. Based on the data that has been compiled in Subak Guama  the efficiency of the use of irrigation water is 76.52%. At present the object of the planting schedule is divided into two groups with different planting schedules between groups of about one month, with the start of the planting schedule starting in February I. If the planting schedule is simultaneously held in February II, the efficiency of irrigation water use is 69.05%. If the planting schedule is carried out systematically by dividing subak into four groups and each group different planting schedules of about half a month and the beginning of the planting schedule in February I, it is obtained that the water use efficiency of irrigation is 86.52%. Thus the planting schedule nyorog can increase the efficiency of irrigation water use through 69.05% to 86.52%.

The growing demand for municipal water due to population increase and urbanization impels water managers to reconsider the existing traditional supply-sided management approach. Strengthening of water demand management (WDM) policies by improving water use efficiency has been adopted as a key target in arid regions, in particular. Indeed, increasing the added value per m3 of water used is gaining importance, since it is a more environmentally-friendly strategy with regard to water resource management than expanding water infrastructure assets. Monitoring the water use efficiency index is the commonly applied method for assessing the performance of municipal water management that depends on physical (real) losses and non-physical (apparent) losses constituting non-revenue water (NRW). In this paper, the results of the study conducted in three medium-size urban settlements, namely Ordu, Çarşamba and Ceyhan, are presented. Field surveys and evaluation of the data relating to municipal customer service have been carried out. In the light of the findings covering a four-year period between 2004–2007, the origin and reasons for NRW, and the means and tools for reducing it in order to improve water use efficiency are discussed.
