The control of transboundary plant diseases and the problem of the public good: Lessons from Fusarium wilt in banana

Many plant diseases and pests cannot be controlled on-farm as they spread from one field or region to another. This opens up a series of interconnected social, political, and economic questions besides the common technical questions about the spread, impact and management of the disease or pest. A new genotype of the soil-born fungus Fusarium, called Tropical Race 4, is extremely virulent, widely destroying banana crops destined for domestic and international markets, and spreading rapidly in Southeast Asia and recently to other countries in the Middle East, Africa, and Latin America. It threatens both staple food production and the export of bananas. The international research and policy-making communities on bananas have been alarmed and are calling for concerted action to control this disease. This paper supports the idea that Fusarium wilt control has to be regarded as a public good but also finds that the public good is being conceptualized in divergent ways. It raises the question as to what gaps exist in the current understanding of providing that public good. The paper identifies a set of key problems, including the problem of anticipation by governments, a neglect of histories of political economic oppositions in the banana sector, the strictures of sovereignty-thinking in multilateral responses, and the aversion that neo-liberal models of governance develop to the public good.
