Examining the Barriers to Redesigning Smallholder Production Practices for Water-Use Efficiency in Numbi, Mbombela Local Municipality, South Africa

Résumé fourni par la source

Smallholder farmers in South Africa face issues related to water shortages and poor irrigation water management. This study investigated barriers to improving water-use efficiency (WUE) in smallholder production practices in Numbi, South Africa. The objectives were to identify barriers in redesigning production practices for higher agricultural productivity and analyze the relationship between irrigation water supply and the adoption of WUE methods. From a population of 7696 people, 141 smallholder farmers were sampled using a simple random sampling technique through Taro Yamane’s sample size formula. The data were analyzed using Pearson’s correlation coefficient and descriptive statistics. Unreliable water supply (M = 3.78, SD = 0.85), poor soil water retention (M = 3.78, SD = 0.85), lack of water-efficient irrigation systems (M = 3.91, SD = 0.71), lack of water storage facilities (M = 3.85, SD = 0.93), limited access to credit (M = 4.09, SD = 0.85), income instability due to market fluctuations (M = 3.96, SD = 0.91), inadequate knowledge of irrigation management (M = 4.00, SD = 0.84), and harsh climatic factors were identified. A positive correlation (r = 0.339, n = 141, p < 0.001) between irrigation water source and WUE techniques was evident, indicating that irrigation water source had an insignificant impact on WUE methods. Resolving these barriers requires a holistic approach focusing on investments in irrigation infrastructure and targeted education initiatives by extension agents and other stakeholders, as this can enhance agricultural productivity.
