“…This could be due to the high yield obtained with AFI7 and lower CWU obtained with AFI14. This result confirms results found by Abdel-Maksoud et al (2002) and Tavakoli and Oweis (2004) for wheat and Webber et al (2006) for common green gram bean production.…”

Alternate furrow irrigation with proper irrigation intervals could save irrigation water and result in high grain yield with low irrigation costs in arid areas. Two field experiments were conducted in the Middle Nile Delta area of Egypt during the 2010 and 2011 seasons to investigate the impact of alternate furrow irrigation with 7-d (AFI7) and 14-d intervals (AFI14) on yield, crop water use efficiency, irrigation water productivity, and economic return of corn (Zea mays L.) as compared with every-furrow irrigation (EFI, conventional method with 14-d interval). Results indicated that grain yield increased under the AFI7 treatment, whereas it tended to decrease under AFI14 as compared with EFI. Irrigation water saving in the AFI7 and AFI14 treatments was approximately 7% and 17%, respectively, as compared to the EFI treatment. The AFI14 and AFI7 treatments improved both crop water use efficiency and irrigation water productivity as compared with EFI. Results also indicated that the AFI7 treatment did not only increase grain yield, but also increased the benefit-cost ratio, net return, and irrigation water saving. Therefore, if low cost water is available and excess water delivery to the field does not require any additional expense, then the AFI7 treatment will essentially be the best choice under the study area conditions.

“…The pressure on water resources is expected to increase as the requirements for food production and industrial needs go up in parallel with the country's rapidly growing population (Webber et al, 2006). Water resources are limited worldwide and there is an urgent need to identify and adopt efficient irrigation management strategies since irrigation of agricultural lands accounts for over 85% of worldwide water usage (Zegbe et al, 2006).…”

Water management efficiency is a key issue for sustainable agriculture development, since it is necessary to get a higher biomass production per unit of applied water. This study aimed to determine both water requirements and water use efficiency (WUE) and their effect on yield and quality parameters in carrots (Daucus carota L.), during the 2006 -2007 growing season in Chillán, Chile (36º 35' 43.2" S, 72º 04' 39" W, 140 m altitude). The water treatments applied were 25, 50, 75, 100 and 125 % pan evaporation (E pan ) in a Haploxerand soil under drip irrigation. The results showed that the highest crop yield was obtained with 100% E pan treatment. However, the highest WUE was found in the 75% E pan treatment equivalent to 3864 m 3 ha -1 , which is the recommended water application level in irrigation scheduling. Regarding carrot crop yield and quality parameters, statistical differences between the different water treatments were not significant, but the increase of applied water (125% E pan ) reduced plant density and root length. This relationship between yield and applied water will allow to improve the management of water resources under water scarcity.

“…In semiarid Uzbekistan, improving water use technologies has been identified as a way to increase agricultural production [23] and meet people's food demands. The introduction of low-cost water-saving technologies and the improvement of on-farm irrigation systems have been found to be the main ways to reduce agricultural water demand and improve the quality of this valuable natural resource [27,28].…”

“…Its 31 million citizens (34% under the age of 14) comprise nearly half of the region's total population [21]. The rapidly growing population has put massive pressure on limited water resources, which has led to water scarcity and the deterioration of water quality [22,23]. The management of water resources in the Aral Sea Basin is a highly complex process that is further complicated by the rising demand for energy and food, environmental degradation, and increased pressure on the region's finite water resources due to economic development, population growth, and climate change [24].…”

Abstract:The rapidly growing population in Uzbekistan has put massive pressure on limited water resources, resulting in frequent water shortages. Irrigation is by far the major water use. Improving irrigation water use through the institutional change of establishing water consumer associations (WCAs) has been identified as a way to increase agricultural production and meet the food demand in the area. However, most WCAs are not fully able to organize collective action or generate sufficient funds to carry out their responsibilities. This study investigated the water-resource-related challenges faced by WCAs and local farmers in Kashkadarya Province in Uzbekistan, using semi-structured expert interviews and focus group discussions. The resulting data were analyzed using qualitative analysis software (Atlas.ti). The results indicated that outdated infrastructure, poor governance, and farmers' non-payment of irrigation service fees hamper sustainable water management. Greater trust and communication within the WCAs would make an important contribution to effective collective action and to the long-term sustainability of local associations.
