Financial Models for Water Sustainability


Apr 30, 2016



Reports on water scarcity have been discouraging. For 40 percent of the global population, demand for water exceeds supply. Within a decade, water scarcity may spread to regions holding 60 percent of the world’s people. Nearly one-third of the world’s 37 largest aquifers are being drained faster than they are being replenished, meaning “groundwater recharge is negative” in eleven of the aquifers. NASA data shows that in California there is only about one year of water supply left in reservoirs, and that total water storage has been in decline since at least 2002. California is in a drought. Yes, but more importantly, California’s water situation is unsustainable.
