Recycled wastewater plays a pivotal role in water sustainability by closing the urban water cycle. This paper studies the wastewater recycling capacity investment decision of a water utility using a two-stage stochastic cost-minimization model under rainfall and recycling cost uncertainties. We characterize the optimal wastewater recycling capacity investment and conduct sensitivity analysis to investigate the impacts of uncertainties on the optimal expected cost and recycling capacity.

Disasters disproportionately affect low-income communities' access to groceries. We study price changes after hurricanes and find higher increases in low-income areas, along with stockouts and substitutions.

Low-income communities face greater price increases, reduced promotions, more stockouts, and increased substitution to higher-priced products.

Disaster response should address pricing, stock management, and equitable access to groceries based on community needs and substitution patterns.

Existing stormwater management fails to address climate-adaptive needs in cities experiencing intensified rainfall. This paper utilizes robust optimization to identify worst-case rainfall scenarios and their impact on flooding loss. It provides guidelines for risk mitigation, optimal infrastructure designs, and emphasizes the urgency of taking action as climate change exacerbates flooding risks.
