Changing to more efficient irrigation technologies in southern Alberta (Canada): An empirical analysis
Release date：2015/10/22 Source： ccap
Jinxia Wang, K. K. Klein, Henning Bjornlund, Lijuan Zhang & Wencui ZhangResults from an irrigator survey in southern Alberta indicate that more than half of irrigators changed irrigation technologies during the five year period (crop year 2007/08 to 2011/12) and this potentially have improved application efficiency. Changes were made from flood irrigation to wheel move sprinklers to high and then low pressure pivot systems. The intended future rate of change is lower than that experienced over the previous five years. Important factors causing these changes were identified: reducing irrigation application, labour and energy inputs, and increasing crop yields and quality. Econometric modelling shows that irrigators who have commenced the process of adopting more efficient sprinklers, are full time farmers, operate their farm as corporations or partnerships, and obtain information from extension agencies, are more likely to upgrade their technologies in the future.
