Managing increasing environmental risks through agrobiodiversity and agrienvironmental policies
Agrobiodiversity can provide natural insurance to risk-averse farmers by reducing the variance of crop yield, and to society at large by reducing the uncertainty in the provision of public-good ecosystem services, for example, CO 2 storage. We analyze the choice of agrobiodiversity by risk-averse farmers who have access to financial insurance, and study the implications for agrienvironmental policy design when on-farm agrobiodiversity generates a positive risk externality. While increasing environmental risk leads private farmers to increase their level of on-farm agrobiodiversity, the level of agrobiodiversity in the laissez-faire equilibrium remains inefficiently low. We show how either one of the two agrienvironmental policy instruments can cure this risk-related market failure: an "ex ante" Pigouvian subsidy on on-farm agrobiodiversity and an "ex post" payment-by-result for the actual provision of public environmental benefits. In the absence of regulation, welfare may increase rather than decrease with increasing environmental risk, if the agroecosystem is characterized by a high natural insurance function, low costs, and large external benefits of agrobiodiversity.
