Desert farming is the practice of developing agriculture in deserts. As agriculture depends upon irrigation and water supply, farming in arid regions where water is scarce is a challenge. However, desert farming has been practiced by humans for thousands of years. In the Negev, there is evidence to suggest agriculture as far back as 5000 BC. [1]
The climate of California varies widely from hot desert to alpine tundra, depending on latitude, elevation, and proximity to the Pacific Coast. California 's coastal regions, the Sierra Nevada foothills, and much of the Central Valley have a Mediterranean climate , with warmer, drier weather in summer and cooler, wetter weather in winter.
California has two high deserts: the Mojave Desert and the Great Basin Desert. The Mojave Desert ecoregion is marked by the presence of Joshua trees. [3] The dry cold Great Basin desert of California consists of the Owens Valley, and is classified into Great Basin shrub steppe by the WWF, [4] and into the Central Basin and Range ecoregion by ...
The lowest-elevation biotic zone in the Sierra Nevada is found along the boundary with the Central Valley. [5] This zone, stretching in elevation from 500 to 3,500 feet (150 to 1,070 m), is the foothill woodland zone, an area that is hot and dry in the summer with very little or no snow in the winter. [5]
If climate change does indeed warm regions where the subalpine zone occurs, conditions there may become more conducive to threats such as invasive species as the local ecosystem is disrupted. Similarly, changes in climate may induce changes in disease ecology which could make native species more vulnerable to disease.

A satellite image of the Sahara, the world's largest hot desert and third largest desert after Antarctica and the Arctic. Desert greening is the process of afforestation or revegetation of deserts for ecological restoration (biodiversity), sustainable farming and forestry, but also for reclamation of natural water systems and other ecological systems that support life.
