Keeping in view the importance of water, present study was conducted in the 13 administrative regions of the country. Using the Random Number Generator, some 230 respondents were selected randomly from each region with the total sample size was of 3000. Some 1800 respondents completely filled the study questionnaire. The study was aimed to examine and provide information regarding comparative perceptions of Saudis and Non-Saudis regarding some issues related to irrigation water; a topic that has not been studied so far. According to study findings, the Non-Saudis farmers have higher awareness about water uses and modern irrigation systems. Significant differences regarding their knowledge on the importance of irrigation water resources, the potential benefits of modern irrigation methods and awareness on the problems faced by farmers regarding water quality in the Kingdom of Saudi Arabia were noticed.
