Business Description and Basis of Presentation [Text Block]	NOTE 1 – DESCRIPTION OF BUSINESS Cadiz Inc. (“Cadiz”, the “Company”) is a natural resources development company committed to providing sustainable water and agricultural opportunities in California. Cadiz owns approximately 45,000 acres of land with high-quality, naturally recharging groundwater resources in three areas of Southern California’s Mojave Desert – the Cadiz Valley (35,000 acres), Danby Dry Lake, (2,000 acres), and the Piute Valley (9,000 acres). Our properties represent a unique private reserve of lands with vested water rights that we own located in a remote area of eastern San Bernardino County that is at the crossroads of major highway, rail, energy and water infrastructure that supply and deliver necessary resources to communities in California and across Western States. Our properties were primarily assembled by our founders in the early 1980s, relying on NASA imagery that identified a unique desert land position at the base of a vast and topographically diverse Southern California watershed with potential for agricultural and water development. The Cadiz Valley property (“Cadiz Property”) is underlain by extensive, high-quality, naturally recharging groundwater able to support a variety of uses. Our main objective is to realize the highest and best use of our land, water and related infrastructure assets in an environmentally responsible way. Our present activities are focused on developing our assets to meet growing long-term demand for access to sustainable water supplies and agricultural products. California has systemic water challenges and is not able to ensure that all people in California can reliably access safe, clean drinking water. We believe that the highest and best use of our assets will be realized by offering a combination of water supply, water storage and agricultural projects in ways that are responsive to California’s resource needs.
