Sustainable conjunctive use of groundwater for additional irrigation
Farmers in the Indus Basin, Pakistan have generally switched to groundwater for additional water supplies due to the irregular supply of irrigation water; currently over 50% of the agricultural land in the basin is at least partially irrigated by tubewells. These wells pump fresh groundwater, which essentially is the result of massive leakage from irrigation canals into the originally saltwater...
متن کاملEvaluating the benefit-cost ratio of groundwater abstraction for additional irrigation water on global scale
ions ( other country GW ) were downscaled to grid level ( other cell GW ) based on proportion of each cell water use in other sector ( MAgPIE Other WU ) to country total water use in other sectors (( MAgPIE Other WU )Country) as obtained from the MAgPIE model results. In the final step, downscaled grid level groundwater abstractions for agriculture and other sectors were addded to get t...
متن کاملGroundwater Quality Assessment for Irrigation Use in Vadodara District, Gujarat, India
This study was conducted to evaluate factors regulating groundwater quality in an area with agriculture as main use. Under this study twelve groundwater samples have been collected from Padra taluka, Dabhoi taluka and Savli taluka of Vadodara district. Groundwater samples were chemically analyzed for major physicochemical parameter in order to understand the different geochemical processes affe...
متن کاملHeavy metals concentrations in groundwater used for irrigation.
BACKGROUND The main objective of this study was characterization of selected heavy metals concentrations (Lead, cadmium, copper, zinc, nickel and chromium) in groundwater used for ir-rigation in Tabriz City's countryside. METHODS After consulting with the experts of agriculture department and site survey, 38 irriga-tion water samples were taken from different farms (34 wells) without primary ...
متن کاملModification of transient state analytical model under different saline groundwater depths, irrigation water salinities and deficit irrigation for quinoa
Salinization of soil is primarily caused by capillary rise from saline shallow groundwater orapplication of saline irrigation water. In this investigation, the transient state analytical modelwas modified to predict water uptake from saline shallow groundwater, actual cropevapotranspiration, soil water content, dry matter, seed yield and soil salinity under differentsaline groundwater depths, i...
