Precision Irrigation Technologies and Sustainable Crop Yield: The Moderating Role of Water Scarcity Adaptation Strategies

Abstract

Agricultural water management is a critical challenge in the context of climate change, population growth, and increasing water scarcity. Precision irrigation technologies, including drip irrigation, automated sprinklers, soil moisture sensors, and remote sensing-based irrigation scheduling, have emerged as transformative tools for enhancing crop productivity and promoting sustainable water use. By optimizing water application according to crop needs and environmental conditions, these technologies can improve water use efficiency, minimize wastage, and support sustainable agriculture. This study investigates the impact of precision irrigation technologies on sustainable crop yield and examines the moderating role of water scarcity adaptation strategies, such as drought-resistant crop varieties, soil moisture conservation techniques, and integrated water management practices. Water scarcity adaptation strategies are posited to strengthen the relationship between precision irrigation adoption and crop yield outcomes by enhancing resilience to water limitations. A quantitative research design was employed, with structured questionnaires administered to farmers, agronomists, and agricultural extension specialists across regions facing varying degrees of water scarcity. Data were analyzed using Smart PLS structural equation modeling to evaluate the direct effect of precision irrigation technologies on crop yield and the moderating effect of adaptation strategies. Findings indicate that precision irrigation technologies significantly enhance sustainable crop yield. The presence of water scarcity adaptation strategies moderates this relationship, amplifying the positive impact of precision irrigation in water-limited environments. The study highlights the importance of integrating technological innovation with adaptive water management practices to ensure resilient, high-yield agricultural systems. These insights inform policymakers, agricultural planners, and extension services in designing interventions for sustainable crop production under water scarcity.
