Business Description and Basis of Presentation [Text Block]	NOTE 1 – DESCRIPTION OF BUSINESS Cadiz Inc. (“Cadiz” or the “Company”) is a land and water resource development company with 45,000 acres of land in three areas of eastern San Bernardino County, California. Virtually all of this land is underlain by high-quality, naturally recharging groundwater resources, and is situated in proximity to the Colorado River and the Colorado River Aqueduct (“CRA”), a major source of imported water for Southern California. The Company’s main objective is to realize the highest and best use of these land and water resources in an environmentally responsible way. For more than 20 years, the Company has maintained an agricultural development at its 34,000-acre property in the Cadiz Valley, relying upon groundwater from the underlying aquifer system for irrigation. In 1993, Cadiz secured permits to develop agriculture on up to 9,600 acres of the Cadiz Valley property and withdraw more than one million acre-feet of groundwater from the underlying aquifer system. Since that time, the Company has maintained various levels of agriculture at the property and this operation has provided its principal source of revenue. At present, the Company’s water development efforts are primarily focused on the Cadiz Valley Water Conservation, Recovery and Storage Project (the “Water Project” or the “Project”), which will capture and conserve millions of acre-feet of native groundwater currently being lost to evaporation from the aquifer system beneath the Company’s Cadiz Valley property and deliver it to water providers throughout Southern California. Cadiz believes that the ultimate implementation of this Water Project will create the primary source of its future cash flow and, accordingly, its working capital requirements relate largely to the development activities associated with this Water Project. The Company also continues to explore additional uses of its land and water resource assets, including additional agricultural opportunities, the development of a land conservation bank on its properties outside the Water Project area and other long-term legacy uses of the Company’s properties such as habitat conservation and cultural uses. In addition to these development efforts, Cadiz will also pursue strategic investments in complementary business or infrastructure to meet its objectives. The Company cannot predict with certainty when or if these objectives will be realized.
