Document Summary
Intro discussion climate change will speed up evaporation of oceans. What can we do better, what can we do differently. Big consumptive use of water is for irrigating crops consumptive vs. non consumptive use: non-cons: water used as power, consumptive: when it is used up or consumed. No federal regulations on quantities of water. Picture: in us we dance in a sprinkler, in third-world countries they struggle to find access to clean drinking water (which leads to a lot of health issues) Precipitation scenario graph: green means rain, red means less the hydrologic cycle will speed up with climate change. Image with graph describing us dams and their height in the us, 75,000 dams at least 6ft high. 97% of irrigation in the us and 99% globally is done by flood or pivot methods solution: center pivot irrigation with dropline: drip irrigation can reduce water use 30-70% while increasing crop yields.
