A study co-authored by UC Berkeley researchers identified the importance of diversity in helping agricultural systems withstand sudden changes.
According to campus doctoral candidate and lead co-author Margiana Petersen-Rockney, the study outlined two different ways the agri-food system currently responds to problems simplification and diversification. The researchers compared two responses across five different case studies in the United States, focusing on challenges including foodborne pathogens, drought, marginal lands, labor availability and land access and tenure.
Simplification, Petersen-Rockney said, has been done in agricultural and food systems for a long time. According to the study, simplification includes processes that narrow the types of crops and livestock raised to maximize production.
