Rising Temperatures in Agriculture

From: Our Changing Climate: Assessing the Risks to California (pdf)

The agriculture industry of California is the largest and the most diverse of the country, producing 300 commodities and half of the country’s fruits and vegetables. As temperatures rise in the state, there will be a direct impact on the water supply, proliferation of pests, outbreak of diseases and overall quality and quantity of the produce.

Many fruit and nut trees are sensitive to temperature changes. As the temperature rises, so does the fruit development rate, resulting in reduced fruit size. A minimum number of chill hours (hours during which temperatures drop below 45 F) is required for proper bud setting; too few hours could cause late or irregular bloom, decreasing fruit quality and subsequent marketable yield. With an increase in overall temperatures, the chill hours are reducing in many areas of the state, rapidly approaching a critical threshold for some fruit trees.
