  1. Solutions to Depletion of Fresh Water Sarah Worley, Sidney Riess, Gabby Sandsness, Madeline Grimm, Kyle Stroh, Kaitlin Miller

  2. Solutions can address supply and demand • Reduce demand • Conservation and efficiency measures • Difficult politically in short term but necessary in the long term • Increase supply • Transport water from more plentiful areas through ground pipes • Water-poor regions take water from areas too weak to support themselves causing dustbowls and destroying rural economies

  3. Desalination “makes” more water • What is Desalination • Reverse osmosis • Evaporation

  4. Agricultural demand can be reduced • Small fixes by farmers makes big differences. -lining canals, leveling fields, etc. • Low-pressure sprinklers reduce water use. • Drip irrigations could cut back water use in half. -Brings in more revenue • Choose crops and climates carefully.

  5. We can lessen residential and industrial water use in many ways • Help Reduce agricultural water • In households, reduce water use • St. Petersburg, Florida and many other cities recycle water • Government in Arizona and England are capturing runoff • Patching leaks=more money

  6. Economic approaches to water conservation are being debated • Make water a full priced commodity • Less available, increases rich-poor gap • Privatization of water supplies • Purchase water from vendors- pay 12x more • Decentralization of control over water from national to local level • Irrigation systems in Mexico improved dramatically • Public education • Decreases water consumption
