Oahu map climate change How Will Climate Change Affect Water Demand? Evidence from Hawai‘i Microclimates January 1, 2021 The effect that climate change will have on water resource sustainability is gaining international interest, particularly in regions where stocks are strained due to changing climate and increasing populations. Past studies focus mainly on how water availability will be affected by climate change, with little attention paid to how consumer behavior is likely to react.… Read More
Estimating water demand using price differences of wastewater services July 27, 2020 Many homes in Hawai‘i use cesspools and other on-site disposal systems (OSDS) instead of the municipal sewer system. Because bills combine water and waste-water services, and homes with OSDS do not pay for sewer service, OSDS residences have lower monthly bills compared to those with sewer-connected systems. We use this price difference in conjunction with… Read More
