To anyone who studies water use in California, it's becoming
increasingly apparent that there is likely to be less water available in
the future for agriculture in the state, because of the impacts of
climate change and population growth.
So finding a constructive way to resolve the conflicts between water
needs for agriculture and for fish populations is essential. In
dialogues like this all over the state, I have seen endless discussions
about how fish populations might survive with less water, but little
discussions of strategies for reducing agricultural water use, such as
regulated deficit irrigation, which allows growing crops with less
water, or of crop shifting.
These seem like essential strategies but they are hardly even
discussed. In a high water cost situation, regulated deficit
irrigation may even increase farmer's profits.
See, for example, Deficit irrigation for reducing agricultural water
use http://jxb.oxfordjournals.org/content/58/2/147.abstract
