Monopolisation of seed is not just a European issue but a global one, with international agritech giants buying out independent companies and leaving farmers with little choice but to purchase hybrid or genetically modified seeds in countries like the US. Monsanto bought 200 US independent seed companies over 10 years, with the corporation now estimated to own 23 % of the proprietary seed market (see  GM Crops Destroyed by Drought in US while non-GM varieties Flourish, SiS 56). A similar drive for seed monopoly is taking place in the African continent, with SeedCo, one of Africa’s largest home-grown seed companies being bought out by transnational corporations Limagrain, the biggest seed and plant breeding company in the EU. Limagrain is investing US$60 million for a 28 % stake in SeedCo . SeedCo has sold 49 % of its shares in Africa’s only cottonseed company Quton to the Indian company Mayco, a Monsanto subsidiary. Syngenta in 2013 took over Zambia’s MRI seed, which is said to have the most biodiverse collection of maize seed varieties in Africa. South Africa’s largest seed company Pannar Seed was recently taken over by Pioneer Hi-Bred, a subsidiary of DuPont. These acquisitions of seed companies by a handful of corporate giants poses great threats not only to seed biodiversity, but also food sovereignty and people’s access to fresh foods, giving GM companies the chance to spread their patented seeds across the world.
Monsanto, Syngenta and DuPont already own 53% of the global commercial seed market and the following legislative proposals and treaties are set to increase their monopoly .
