  7. In September/October 2002, develop an analysis and journal article on the impact of water shortages on the horticulture industry (statistical estimate of the relationship between our regional water supply and subsequent horticulture supply behavior/decisions by farmers.) Provide guidance to irrigation district managers about the influence of water supply on cropping patterns within their districts.
