When water availability diminishes, food crops tend to suffer.
TreeHugger has an excellent discussion of the impact of drought on food production in Australia.
Rice is a water intensive crop, and when drought hits, production suffers. In Australia, “production has dropped from 1.6 million tons in 2000 to a mere 18,000 tons in 2008.”
This has important implications for planning for climate change.
Taking the experience of Australia to heart now can help other areas be proactive about water use and avoid sharp changes in agriculture, and therefore economy, such as what Australia is now facing. Getting started today and reduce our water use to only what we need as well as make practical decisions in the agricultural sector, can help a region avoid a more dire crisis in the future.
