The Editor The Guardian London Dear Sir WTO and FAO International Treaty on Plant Genetic Resources for Food and Agriculture Global public goods may also be sacrificed at the altar of Doha if the WTO ignores last weekend's decision in Rome. Naomi Klein (Doha, the economic frontline, Nov 8) rightly points out that developing country needs and "petty concerns about mass poverty" may be well be overridden by WTO fanaticism. But developing countries and the liberal majority in OECD countries should take heart from events in Rome last weekend when a landmark but underreported event occurred: the adoption by the 184 nation Food and Agriculture Organisation of the United Nations of an International Treaty to safeguard, in the public domain, the basis of global food security - the seeds of the world's most important crop and forage plants. This legally binding Treaty, the result of 7 anguished years of negotiations, is called the International Treaty on Plant Genetic Resources for Food and Agriculture. As the Director General of FAO, Jacques Diouf, noted in his celebratory speech "This Treaty... is at the crossroads where agriculture, environment and trade meet." Despite last minute attempts by the USA, backed by Australia, Canada, Japan and a few others, to remove the key clause in the treaty which exempts these vital resources from Intellectual Property Rights, and subsequent statements that they would not recognise any interpretation of this clause as limiting their right to patent seeds and genes, the treaty was overwhelmingly adopted. Developing countries, the European region, the international agricultural research community and Civil Society Organisations all welcomed the decision, although each noted weaknesses that will now have to be addressed by the Treaty's Governing Body. The Treaty covers 35 of the world's most important crops that, together, provide more than 70% of human dietary energy needs - but the Governing Body should expand this list to include especially those crops that are important for oil, protein, vitamin and mineral components of our diet. It prevents countries from recognising IPRs on these crops - but the Governing Body will have to remove ambiguities that might allow corporations to cherry-pick and patent genes extracted from these crops. It provides for mandatory sharing of profits from the use of genetic resources covered by the Treaty with the developing world's farmers, who created our food crops - but the Governing Body will have to find ways of increasing these so that they are commensurate with the contribution that these genetic resources make to the multi-trillion dollar food industry. The Treaty recognises Farmers' Rights to access seeds, share and sell these and participate in relevant decision making fora - but the Governing Body must find ways of making these Rights are internationally recognised and not subject to national law. This landmark Treaty could be immediately undermined by the WTO if it overrides developing country demands for a full review of the gene patent exemption article in the Agreement on Trade Related aspects of Intellectual Property Rights - TRIPs Article 27.3(b). This article allows countries to exempt plants, plant varieties and animals from patenting, but the USA is pressuring for deletion of this clause. This is the first international treaty of the new century and, significantly, it is a treaty that defends global public goods. WTO negotiators would redeem themselves to some extent if they were explicitly to recognise and support the new Treaty, which will be so important in fight against hunger.
