Abstract
Smart water management systems (SWMS) have been increasingly adopted in semi-arid regions to improve irrigation efficiency and reduce water wastage. A comprehensive search strategy was employed across databases like Web of Science, Scopus, and Google Scholar. Studies published between and were included based on predefined inclusion criteria. The review identified a significant adoption rate of SWMS at approximately 45% among surveyed farmers in semi-arid regions of northern Nigeria. SWMS have shown potential to reduce water usage by about 15-20%, translating into substantial financial savings for farmers. Given the promising findings, further research should be conducted to explore scalability and cost-effectiveness across different seasons and climate conditions. Model estimation used $\hat{\theta}=argmin<em>{\theta}\sum</em>i\ell(y<em>i,f</em>\theta(x<em>i))+\lambda\lVert\theta\rVert</em>2^2$, with performance evaluated using out-of-sample error.
