Exploring the Socio-Cultural Factors Influencing the Persistence of Traditional Flood Irrigation in Al Ula, Kingdom of Saudi Arabia.

Abstract

This dissertation examines the socio-cultural factors that contribute to the continued use of traditional flood irrigation among farmers in Al Ula, Saudi Arabia, despite rising water scarcity and the existence of more effective options (modern irrigation methods), such as drip irrigation and sprinkler irrigation. Al Ula's oasis agriculture is heavily dependent on the non-renewable Saq-Ram aquifer, where unsustainable withdrawals and flood irrigation practices have hastened groundwater depletion, salinity building, and nitrate contamination. While Saudi Arabia's Vision 2030 emphasises modern irrigation as a national goal, adoption remains low in Al Ula, indicating that technical and economic explanations are insufficient. This study, guided by the Theory of Planned Behaviour (TPB), utilizes a qualitative, exploratory approach to investigate how social norms, attitudes, perceived behavioural control, and broader cultural traditions influence irrigation decisions. Data were collected through 20 semi-structured interviews with farmers, which were conducted partly through snowball sampling on participants' farms and partly through an opportunistic approach at the Al Ula Fruit Festival, and complemented with direct field observations. Transcripts were analysed thematically. The study found that dependence on flood irrigation is fuelled by cultural continuity, family heritage, and peer influence, as well as practical views of simplicity, price, and crop quality. Partial modernization, such as installing pipelines to convey water while still flooding basins, reflects common misunderstandings and risk aversion. Although farmers realized groundwater depletion, they prioritized immediate output and profit, revealing an awareness-action gap. Notably, participants stated a conditional willingness to implement modern irrigation if financial, technical, and institutional support were offered. This study contributes to theory by expanding TPB to include social reinforcement and cultural identity, as well as to practice by emphasising the importance of culturally sensitive, farmer-centred policy. Addressing Al Ula's irrigation dilemma necessitates solutions that are solved not only by transferring technology but also interacting with the socio-cultural factors that underpin traditional practices.
