Home to farmers growing everything from avocadoes tostrawberriesand almonds totomatoes , California ’s 450 - mile - long Central Valley has long been associated with production agriculture — rightfully so , given that in 2007 , the region leave 76.5 percent of all agricultural yield in California .

This does n’t intend that every Fannie Farmer in the Central Valley ’s green goods is bind for supermarket shelf , however . In fact , according to recent findings by a team of University of California , Davis - base researchers , community - support agriculturehas taken wait in the region , providing farmers a profitable direct - marketing wall socket and consumers access to food from growers they have intercourse and trustfulness .

Although the first CSA cognitive process emerged on the East Coast in the 1980s , the model is n’t unexampled to Californians , says Ryan Galt , helper prof of agricultural sustainability and society at UC Davis . However , he say , there are marked socioeconomic difference between parts of the state where the CSA model is popular and wide approachable , such as Santa Cruz and the San Francisco Bay Area , and the Central Valley and its surrounding foothills .

In addition to having an thriftiness based on agriculture , the Central Valley is “ a poorer region of the country ” and has a less - educated world , Galt reports . He also describes the Central Valley ’s population , on average , to be “ politically conservative … and opposed to authorities regularization and intervention . ” Galt read this unparalleled circumstance was part of what puff his team to the region .

The Galt and his team cull its research depicted object from on-line list of California CSAs , including databases hosted by LocalHarvest and the Robyn Van En Center . The researchers detect 276 CSAs in the state and , through GIS chromosome mapping , identified 101 in their study areas .

At the beginning of the project , they had agree to use a commonly - understood definition of CSA :   a business role model wherein member pay up front for a time of year ’s worth of shares and partake risks with the farmer . As they get through the 101 farm in their study area , they found it necessary to revise this definition to admit farms that used dissimilar payment social organization or schedule , growers that collaborated on multi - farm CSAs , and farm - linked collector CSAs , where raiser ’ part corner included not just their own product but other farm goodness that they ’d purchased from another farm or a wholesale grocery .

“ The definitional dubiousness is very bounteous because it ’s very catchy , ” Galt says . While variant on the CSA model reflect expanded marketing possibilities for sodbuster , it ’s also given boost to what Galt and his team consult to as nonfarm aggregators — retailers that grow nothing themselves and or else purchase produce at wholesale and grocery store it , boxful - mode , under the label of a CSA . Because online list commonly are n’t policed , Galt tell , these “ fake CSAs ” will advertise alongside schematic CSAs and , at times , “ even slenderly undercut CSA sodbuster ” on price .

Galt summate that the issues raised by community of interests - supported agriculture ’s evolve ( and light - to - manipulate ) definition are present on a internal scale , bring up the first - ever mention of community - supported agriculture on the U.S. Census of Agriculture . When demand about their involvement in a CSA selling arrangement , “ many more Farmer than we thought would answer ‘ yes ’ to this inquiry , ” he say .

In Stanislaus County , Calif. , for example , 30 CSA farmers were identified in the census , while Galt say the number is likely closer to four or five . Nationally , the census identified 12,549 CSA farmers , whereas a reckoning on LocalHarvest is closer to 3,000 . Galt attribute this “ massive variant ” not only to fake CSAs , but also to farmers ’ own misunderstanding of the census question — and the condition ’s definition .

After weeding out fake CSAs and those no longer in mathematical operation ( call “ ghost CSAs ” by Galt and his team ) , the researchers were give with a inquiry pool of 54 CSA Farmer and two CSA organizers who they interview and surveyed on subject include profitability , farm merchandising and management , and the philosophical and political underpinnings of their business .

Although the definition of profitableness can be just as nebulous as the definition of community - supported agriculture itself , a majority of respondents ( 54 per centum ) said their CSA was profitable , and 1/3 reported compensate themselves a salary in 2009 . The investigator also ascertain that most Central Valley CSA farmers do n’t reckon solely on CSAs for their farm income : They also pursue other lineal - selling avenues , such asfarmers ’ markets , and often have marketing arrangements with eating place , institutions and wholesalers . On average , James Leonard Farmer report obtain 58 percent of perfect farm sales from their CSA .

Galt says he and his squad were pleasantly surprise by “ the various political philosophies that CSA Fannie Merritt Farmer bring to their workplace . ” Whereas the CSA model is often connect with leftist perspective — specially in California , where many farmers and organizers cut their teeth at UC Santa Cruz ’s CSA farm , “ with its connotations of flower child culture”—the husbandman in the UC Davis study self - distinguish with such viewpoints as libertarianism , socialism , evangelical Christianity and feminism .

“ The CSA farming population is far more politically diverse in their views than we typically associate with the alternative solid food motion , ” Galt tell . This lead him hopeful that there ’s a possibility “ for local food systems tie with a change of political orientation . ”

The team ’s initial determination were published in the January - March 2012 issue of the journalCalifornia Agriculture .
