A salt on the land: A narrative analysis of the controversy over irrigation-related salinity and toxicity in California's San Joaquin Valley

A narrative network analysis of the seeming paralysis of efforts to deal with the problem of toxic elements in agricultural drainage in California's San Joaquin Valley shows irrigation agencies to be caught in a dilemma. Despite pressures to reduce uncertainty about treatment methods, reducing this uncertainty risks increased political polarization over agricultural subsidies. As a result, policy-makers are reluctant to move in any action-forcing direction, and continue to order further studies. We sketch out those areas of contention that must be addressed if real progress is to be made, demonstrating that the issues are primarily organizational and political rather than technical. We also discuss our experience in presenting these findings, along with our recommendations for structural separation of drainage functions from present irrigation agencies, to the relevant policy audience.
