GEOLOGY

Detailed explanation-1: -We can adapt to future droughts through reducing our water use and switching to more sustainable water uses. We can expand our existing usage of recycled water, replenish our groundwater aquifers and increase our flexibility in crop and municipal uses.

Detailed explanation-2: -California is taking urgent action to protect communities from climate-driven extremes in weather and expand the state’s capacity to capture storm runoff in wet years. Strategies to boost water supplies (this is a pdf file) include groundwater recharge, stormwater capture, reservoir storage and more.

Detailed explanation-3: -DRIED UP: In California, desalination offers only partial solution to growing drought. The American West is experiencing its driest period in human history, a megadrought that threatens health, agriculture and entire ways of life.

Detailed explanation-4: -There are three main types of thermal desalination – vapour compression (VC), multi-effect distillation (MED) and multi-stage flash distillation (MSF).
