For the ordinary urban farmer here in S.Florida there are two kinds of challenges.
1-The man made ..
2-The Nature Made.
Here in Flotrida we have the EVERGLADES and the once known RIVER of GRASS.Both were the natural feeding water system to the acquifers and water resources.Untill man made canals were dug into the land to carry out and drain the water into the Atalntic and Gulf of Mexico to make room for development .
Now we are crying wolf and rushing to impose fines and water restrictions as water becomes so scarce with the never ending DRAUGHT !
The climate change is changing theway we do agriculture world wide as water becopmes less available.So man invented a solution :Water banks.
Well , it is not that NEW innovation or discovery as you might change the name of water wells to water banks per se!
I personally use the RAIN BARRELS as an alternative.You might be interested in the Water Banks , here are some sources:

The Chinese proverb goes: It is better to light a candle rather than curse darkness.
Offering and sharing solutions is the positive way to meet the challenges .Have you done your share in sharing some positive thought srecently to convert a lemon into a lemonade?
