The consolidation of corporate power in agriculture has been in the news a lot lately, first with the proposed ChemChina-Syngenta and Dow-DuPont mergers, and now with Bayer’s proposal to purchase seed giant Monsanto. National Farmers Union president Roger Johnson testified in Congress last week that the proposed mergers would enable just three corporations to control 80 percent of the U.S. seed supply (and 70 percent of the global pesticide market). This expansion of corporate control is also happening in three international treaties that establish the global rights of various stakeholders to seeds, germplasm, and plant varieties. Each of these treaties strikes a certain balance among those interests. And recently, like the agribusiness mergers, the balance has been tilting away from the interests of smaller-scale farmers and diversified agriculture. Unsurprisingly, corporations interested in accessing seeds and other genetic resources are pushing hard on all fronts.
