Abstract: | While the relations between climate variables and sectoral water demand have been well established in the literature, few
studies have attempted to quantify changes in urban water usage with climate change. Concentrating on the city of Hamilton,
New Zealand, we investigate possible water use and infrastructure needs for a range of climate and population projections.
We find that water demand (at the monthly aggregate level) is largely driven by changes in population, and not significantly
affected by changes in climate. However, as population increases, the effect of climate variables on per capita consumption
will be magnified. Monthly aggregate changes may further mask potenially significant short-term shortages. In several scenarios,
water supply shortages in 2030 occur with a 30--40% probability, suggesting needs for long-term capacity expansion or aggressive
demand side management, rather than implementation of short-term management of water demand. |
