Southern Central Valley RegionCounties: Fresno, Kern, Kings, TulareFive Largest Cities (CDOF, 2011): Fresno (500,121); Bakersfield (351,443);Visalia (125,770); Clovis (97,218); Tulare (59,926)Total 2010 PopulationSouthernCentral Valley2,365,242Fresno 930,450Kern 839,631Kings 152,982Tulare 442,179[U.S. Census Bureau, 2010]The Southern Central Valley is a largely agricultural, inland region with over 2million people. Its regional character is defined largely by agriculture, interspersedwith cities along primary transport corridors, with Fresno (500,000+ people)prominent in the northern end and Bakersfield (350,000+ people) in thesouthern end. Agriculture is the predominant economic activity; the regioncontained the top three agricultural counties in the state in 2010 when evaluatedon value, totaling roughly $16 billion California Farm Bureau Federation, 2012).The region also stretches into the foothills of the Sierra Nevada and is knownas a prominent tourism access point for Yosemite National Park, Kings CanyonNational Park, and Sequoia National Park. Several communities in the region relyon tourism.Communities in the Southern Central Valley should evaluate vulnerability to thefollowing impacts:• Temperature increases• Reduced precipitation• Reduced water supply• Reduced agricultural productivity• Flooding• Decrease in tourism – Sierra Nevada foothills• Wildfire risk in the Sierra Nevada foothillsPAGE 58APG: UNDERSTANDING REGIONAL CHARACTERISTICS
Cal-Adapt ProjectionsTable 21. Summary of Cal-Adapt Climate Projections for the Southern Central Valley RegionEffectTemperatureChange,1990-2100PrecipitationSnowpackHeat WaveWildfire RiskRangesJanuary increase in average temperatures: 3°F to 4°F by 2050 and 7°F to 10°F by 2100.July increase in average temperatures: 5°F to 6°F in 2050 and 9°F to 11°F by 2100, withlarger temperature increases in the mountainous regions to the east.(Modeled high temperatures; average of all models; high carbon emissions scenario)Low areas are projected to experience declines in annual precipitationof 1 or 2 inches by 2050 and up to 3.5 inches by 2100, while moreelevated areas are projected to experiences loses of up to 10 inches.(CCSM3 climate model; high carbon emissions scenario)Snowpack in the eastern elevated regions is projected to decrease byapproximately 9 inches, resulting in pack that is less than 4 inches by March 2090.(CCSM3 climate model; high carbon emissions scenario)The threshold temperature that defines a heat wave is over 100°F in most of the region.In the mountains, a heat wave is defined by lower termperatures, 70°F to 90°F. By 2050,the number annual heat waves is projected to increase by three to five. An increaseof seven to 10 is expected by 2100 in most of the region, with an increase of up to 14expected in the mountain areas.The eastern edge of the region is projected to experiencean increase in wildfire risk of 4 to 6 times current conditions.(GFDL model; high carbon emissions scenario)[Public Interest Energy Research, 2011. Cal-Adapt. Retrieved from http://cal-adapt.org]Water SourcesMost of the Southern Central Valley region is located within the Tulare Lake hydrologic region. Thewater supply in this region relies primarily on Sierra snowmelt, delivered by natural waterwaysand canal systems, and groundwater. During parts of the year, water is limited. As a result, theregion has developed a careful management system, integrating groundwater and surface waterresources to assure year-round supply (DWR, 2009). This management system seeks to avoidgroundwater overdraft but has not always succeeded, leading to increased water table depths andassociated land subsidence.Within the region, western areas are subject to more limited resources. Therefore, they relyon imported resources from the Central Valley Project and the State Water Project. Theseimported sources have increased salt concentrations, which have led to a salt build-up in soils andgroundwater.Agriculture is the largest water user in the region (more than 80 percent), followed byenvironmental and urban uses. In addition, the extensive network of reservoirs is used for powergeneration and storage. Reservoir storage capacity in the region totals 2.05 million acre-feet(DWR, 2009).APG: UNDERSTANDING REGIONAL CHARACTERISTICS PAGE 59
