Water resources are essential to sustain human life and natural ecosystems, yet increasing stresses from population growth, urbanization, and climate change pose challenges to sustainable water resource management. Integrated Water Resources Management provides a holistic approach to address these challenges by considering the interconnectedness of water uses and the need for coordinated management. Innovative practices, adaptive policies, and equitable outcomes for people are critical for sustainable and just water resource management that meets the needs of a growing population amidst the mounting pressures of climate change.Innovative practices in stormwater management can help mitigate water resource challenges from stressors like urbanization and climate change. Incorporating pretreatment into bioretention systems is an innovative practice that can reduce suspended particle concentrations, preserve well-established vegetation, and lead to improved system performance. A case study of a bioretention cell in Johnston, IA, demonstrated that the pre-treatment structure reduced the average concentration of suspended particles by 37%. Further, modeling showed water quality and quantity benefits, including a 62% reduction in the mass load of suspended particles and an 80% reduction in the peak flowrate directed to the storm sewer. This case study contributes insights into the benefits, trade-offs, and design considerations of pre-treatment for bioretention systems, which are critical to advancing sustainable stormwater management.Applying adaptive management, such as monitoring and assessing the effectiveness of policies, is critical for improving sustainable water resource management. Our study evaluating the effectiveness of a stormwater ordinance in Clive, IA, found that the mandated stormwater management practices effectively reduced peak flow and time to peak, particularly for longer storms that more closely resembled those used in the design criteria. However, observed storms had more variation in duration and intensity compared to the uniform, 24-hr storms prescribed for design, sometimes resulting in higher flows than predicted but not leading to flood risk. The study highlights the need to consider observed or projected precipitation data in design and policy to mitigate challenges posed by urbanization and climate change.The holistic approach of Integrated Water Resources Management requires considering interdependencies between water and other critical systems that affect equitable outcomes. Equity principles can be implemented by investigating how barriers to food, energy, and water systems (FEWS) affordability, access, and quality impact socially vulnerable people. Our study focusing on these intersections across climates and the urban-rural divide in the US found variations and notable disparities for vulnerable populations in specific regions (e.g., Subarctic rural regions, Hot-Humid urban areas). Affordability barriers had an increasing likelihood of being high for populations who were vulnerable due to their racial or ethnic minority status. In contrast, high access and quality barriers were associated with socioeconomic and household characteristic vulnerabilities. This study provides a framework for social equity considerations within the FEWS nexus to inform policy and strategies for improving social equity in the US. Our findings underscore the need for interventions to correct historical legacies and dismantle barriers to equitable FEWS provisioning.
