Improved Understanding of Climate Variability and Change Relevant to Orchards and Vineyards in Arizona and New Mexico

CLIMAS Lead:  

Orchards and vineyards are particularly sensitive to temperature, and we currently lack information about how recent warming in the Southwest has affected—and how future anticipated increases in temperature might affect—the climatic conditions important to orchards and vineyards. This project will work closely with Arizona and New Mexico Cooperative Extensions and individual farmers to survey a set of orchards and vineyards currently under production to gather information about their siting and cultivars. An assessment will be made of the required temperature conditions for the current cultivars, whether these have historically been met, and if they are likely to be met in the coming decades. Crop insurance indemnity records will be used to perform a financial assessment of how site and cultivar selection are functioning in the current regional climate. The suitability of present-day orchards and vineyards will be evaluated in the context of anticipated increases in regional temperature.
