    Abstract The shortage of fresh water is a major problem throughout the world, but the situation is worst in the arid and semiarid regions. Therefore, reuse of nonconventional water resources such as treated wastewater (TWW) is a common practice to irrigate field crops, vegetables, and forestry sectors. The present study was conducted to evaluate the significant impact of different heavy metals such as copper (Cu), iron (Fe), chromium (Cr), and zinc (Zn) on the soil and leafy, root, and fruit vegetables following irrigation with TWW through subsurface drip irrigation. Our results indicate that iron (Fe) was highest in lettuce followed by spinach, and Zn and Cr were second and third most abundant element in the different vegetables. Eggplant and radish showed the lowest concentrations of various heavy metals. A significant difference was observed in transfer factor (TF) among vegetables, and highest TF

    Abstract Ethiopia’s irrigated agriculture productivity has been threatened by severe salinity and sodicity problems which have resulted in significantly lower yields, food insecurity, and environmental degradation. The destructive effects of poor irrigation water management with the absence of drainage and anticipated future climate changes can accelerate the formation of salt-affected soil, potentially expanding the problem to currently unaffected regions. This paper synthesizes the available information on the causes, extent, and effects of salt-affected soils on soil and crop production and suggest chemical, biological, and physical reclamation and management approaches for tackling salinity and sodicity problems. The mitigation approaches (e.g., the addition of amendments, plantation of salt-tolerant crops, appropriate irrigation and drainage management, phytoremediation, and bioremediation) have successfully tackled soil salinity and sodicity problems in many parts of the world. These approaches have further improved the socioeconomic conditions of farming communities in salt-affected areas. The paper also discusses the effectiveness of these mitigation strategies under Ethiopian conditions. The policy interventions for reclamation of soil salinity and sodicity that indicates future research attention to restoring agricultural sustainability are also foci of this paper.

Therefore, reuse of nonconventional water resources such as treated wastewater (TWW) is a common practice to irrigate field crops, vegetables, and forestry sectors. The present study was conducted to evaluate the significant impact of different heavy metals such as copper (Cu), iron (Fe), chromium (Cr), and zinc (Zn) on the soil and leafy, root, and fruit vegetables following irrigation with TWW through subsurface drip irrigation. Our results indicate that iron (Fe) was highest in lettuce followed by spinach, and Zn and Cr were second and third most abundant element in the different vegetables. Eggplant and radish showed the lowest concentrations of various heavy metals. A significant difference was observed in transfer factor (TF) among vegetables, and highest TFsoil−veg was observed for Fe in lettuce and the lowest for Cr in eggplant. Estimated daily intake (EDI) was the lowest in adults and highest in children. Target hazard quotient (THQ) of Cu, Zn, and Fe being < 1.0 appears relatively safe in all the tested vegetables. Risk index (RI) values showed that heavy metals were lower than 1.0 and hence lower risk for human. The combined HI values for Cu, Zn, Cd, Cr, and Pb were substaintionaly higher 12.8 and 9.21 after consumption of lettuce and carrot. So, consumption of these vegetables should be avoided after irrigation with TWW. Spinach exhibited maximum total coliform loading, while ecological risk was negligible due to sandy nature of soil type. Health risks to human could be reduced through proper selection of suitable vegetables, time of maturity, and consumed organs (leaf, fruit, or root part). Appropriate should be followed to decontaminate the microbial load in order to avoid any risks to human health (both adults and children).

    Abstract Paper presented at the Joint IWMI-AREO Workshop, Karaj, Iran, 22-23 September 2004

    Irrigated agriculture and, consequently, water have always played an important role in the economic development of Iran and is likely to continue as such in the future. Since agriculture is the major user of water, therefore sustainability of agriculture depends on the timely and adequate availability of water. The increasing pressures of population and industrialization have already placed greater demands on water, with an everincreasing number and intensity of local and regional conflicts over its availability and use. Iran will face severe water shortages in the 21st century. The gap between demand and supply of water is increasing. The extended drought during recent years exacerbated the problem. Therefore, the need for further development of new resources, adoption of water-conservation measures and judicious use of water is being stressed at all forums. This paper will provide a comprehensive review of the present water resources of Iran, challenges faced by the irrigated agriculture and strategies to overcome these problems to ensure sustainability of irrigated agriculture. This paper will also suggest possible research areas for future cooperation between IWMI and Iran in the field of land and water management. It is envisaged that discussions at the workshop will help in refining these ideas and develop partnerships and linkages among various national research institutions and IWMI to develop a comprehensive program for the years to come.

    Abstract Increasing use of groundwater for irrigation is linked to high energy demand, depleting resources and resulting in a high carbon footprint. This paper explores how improved on‐farm irrigation management can help in reducing groundwater extraction, limiting energy consumption and CO₂ emissions. In Pakistan, every year about 50 billion cubic metres (BCM) of groundwater is pumped for irrigation, which consumes more than 6 billion kWh of electricity and 3.5 billion litres of diesel. Carbon emissions attributed to this energy use amount to 3.8 million metric tons (MMT) of CO₂ per year. Considerable research carried out in Pakistan has suggested that improved irrigation management can significantly reduce the irrigation water applied to different crops. This study revealed that by adopting improved irrigation schedules, water productivity will increase and groundwater withdrawals for irrigation can be reduced by 24 BCM. Reduced groundwater extraction will result in a 62% decline in energy demand (1.5 billion litres of diesel as most of the private tubewells run on diesel) and a 40% reduction in carbon emissions. In addition, a reduction in irrigation applications will also be beneficial for stabilizing groundwater tables and groundwater quality.
