| Abstract | Agriculturehas fundamental importance for human kind and it is highest consumption sector of fresh water resources. Rising population causingserious threatsto the food availability and demand for future population. Water availability is reducing for agriculture causing reduction in overall crop production. Pakistan is an agricultural country having about 26% of GDP contribution of agriculture.Water footprint technique was used to calculate water consumption by rice and wheat crops in Gujranwala district, Pakistan. Kuthiali minor canal system in Gujranwala district was selected as study area. WF for rice and wheat crops were calculated for five cropping seasons form 2010 -2014. Average water footprintcalculated for ricewas3,328 l/kg (37% green, 38% blue, 25% grey) which was high as compare to averagewater footprint of rice produced in Indiai.e. 2,019 l/kg. Whereasfor wheat production water footprint was1,474 l/kg (16% green, 31% blue, 53% grey) which is lower than the wheat produced in India i.e.2,104l/kg. Canal performance in terms ofwater supply was in deficit during summerand winters seasons.The overall efficiency of canal system for whole cropping seasons was found out to be 65.5%.AquaCrop 4.0 model was used to simulatecrop yield under different croppingcalendarsand irrigation water application depth. Resultsobtained for water footprintfor improved irrigation system by shifting transplanting date shows change in water footprintfor all components(green, blue and grey). Results obtained showed that, for rice crop,there will be a decrease in water footprint by (35% green, 20% blue and 15% grey) by shifting transplanting date from 25thJune to 20thof July. For wheat crop decrease in water footprint were seen (7% green, 37% blue, 12% grey) by shifting sowing date from 1stof December to 10thof November. Scenario of changingwater application depthshows insignificant variation in water footprint.Since WF results by shifting crop calendar for rice and wheat crop providing less values of water footprint. It is a useful information for making a decision in accordance to reduce water consumption per unit of crop production. |
