“…Given the high sensitivity of population growth to water stress in most regions in Texas, encouraging water conservation and efficiency measures at the individual, household, and business levels can effectively reduce total water demand. Several strategies can be employed, such as increasing public awareness, water conservation education [1], and the use of water-efficient appliances and fixtures in new constructions or renovations; (3) Promoting sustainable water use in agriculture. The expansion of irrigated croplands can be achieved through the adoption of precision irrigation technologies, such as soil moisture sensors [45], drip irrigation [46], and precision sprinkler systems [38], which may offset its adverse impacts on irrigation water use.…”

“…Water is a fundamental resource for human activities, including food production, energy generation, and domestic and industrial uses [1]. The global demand for freshwater has increased significantly since the 1950s, mainly due to population growth, urbanization, industrialization, and rising food and energy needs [1]. Moreover, the ongoing COVID-19 pandemic has led to changes in water consumption patterns [2][3][4].…”

Climate change, socioeconomic development, and irrigation management are exacerbating water scarcity in many regions worldwide. However, current global-scale modeling approaches used to evaluate the impact of these factors on water resources are limited by coarse resolution and simplified representation of local socioeconomic and agricultural systems, which hinders their use for regional decision making. Here, we upgraded the irrigation water use simulation in the system dynamics and water environmental model (SyDWEM) and integrated it with the water supply stress index (WaSSI) ecosystem services model. This integrated model (SyDWEM-WaSSI) simulated local socioeconomic and agricultural systems to accurately assess future water stress associated with climate change, socioeconomic development, and agricultural management at subbasin levels. We calibrated the integrated model and applied it to assess future water stress levels in Texas from 2015 to 2050. The water stress index (WSI), defined as the ratio of water withdrawal to availability, was used to indicate different water stress levels. Our results showed that the integrated model captured changes in water demand across various sectors and the impact of climate change on water supply. Projected high water stress areas (WSI > 0.4) are expected to increase significantly by 2050, particularly in the Texas High Plains and Rolling Plains regions, where irrigation water use was projected to rise due to the impact of climate change. Metropolitan areas, including Dallas, Houston, Austin, and San Antonio, were also expected to experience increased domestic water demand, further exacerbating water stress in these areas. Our study highlights the need to incorporate socioeconomic planning into water resources management. The integrated model is a valuable tool for decisionmakers and stakeholders to evaluate the impacts of climate change, socioeconomic development, and irrigation management on water resources at the local scale.
