摘要:Decades of voluntary efforts to reduce agricultural nonpoint source
pollution have been ineffective at protecting water quality worldwide. While
farmer collective action is needed to deal with the geographical extent of diffuse
pollution from nutrient runoff, theoretical expectations from commons governance
research predicts that farmers will not protect water quality since they
have few incentives to do so. These different factors indicate that compulsory
approaches are needed. However, the commons literature has tended to overlook
the constructive roles that government regulation can play. Research on why farmers
adopt on-farm conservation measures similarly has failed to explore farmer
cooperation, instead focusing mainly on financial motivations of farmers. Yet,
some adoption research indicates that social norms are essential factors shaping
(non)adoption, but which are largely overlooked by existing agri-environmental
policies. This study examines the important gap of how government regulations
can incentivise farmer cooperation to improve water quality. I focus on a case
study of the Florida Everglades, where farmers face joint liability under a phosphorus
pollution cap and which has resulted in improvements in water quality
over the past 20 years. Farms’ drainage disrupts the oligotrophic conditions of
the Florida Everglades, but water quality has steadily improved since regulations
began in 1994. However, the regulations set compliance jointly for farmers,
devolving responsibility to ensure sufficient adoption of conservation practices
and deal with free riding. While state monitoring shows that collectively farms
have improved water quality, we do not know whether participation is widespread
or concentrated among a few large farms. This study provides the first analysis
of farm-level water quality outcomes for this area and how judicial, legislative,
and local institutions interact to encourage farmer cooperation. Results show
that a large majority of farms have improved their water quality, demonstrating
that collective action has been a key element in the outcome. At the same time,
poor-performing farms reveal the shortcomings of joint compliance. I end by discussing the implications of how individual and collective requirements can
provide farmers with valuable information while also drawing on farmer social
dynamics to encourage greater participation.
