Closed system l Water ¡ Rain l We and evaporation should always have enough water ¡ But l Per equation will it be potable? capita consumption is doubling every 20 years—households only account for 10%

Who is using it? 20 -25% industry l 65 -75% agriculture (only 50% makes it to crops) l ¡ l Massive pollution of surface waters ¡ l Industrial farming with subsidies; no need to conserve Deforestation, wetland destruction, pesticides. Fertilizer, global warming BY 2025 2. 6 billion more people on earth ¡ ¡ 2/3 will be living in conditions of shortage; 1/3 in scarcity Demand will exceed availability by 56%

What about Agriculture…. l 65% globally l 80 -90% SW USA ¡ Little l conservation b/c water is cheap Central Valley Project • Subsidized water-20% of the CO river flows • Sold back to CA (rights, after all) • COST = CO River delta, Sacramento River Salmon l This has changed somewhat after a six year drought (late 1980 s) • Increased from 3$ to 30$ acre/foot

Aquifer Overpumping l High plains - US: 20% of all US irrigated lands ¡ ¡ l l l l depletion rate = 12 billion cubic meters/yr irrigated area in TX high plains dropped 26% 1979 -1989 California - depleting groundwater by 1. 6 billion m 3/yr (15% net gw use) Arizona - water tables have dropped >120 meters; overpumping = 1. 2 b m 3/yr Mexico City and Valley of MX - pumping exceeds recharge by 5080% Saudi Arabia - 75% of all water used is from nonrenewable groundwater India - gw supplies half of irrigation water- aggregate deficit of 100 billion m 3/yr N. China - overpumping 30 bcm/yr Israel and Gaza - pumping exceeds recharge by about 60%
