Participatory Plant Breeding, Biodiversity, Genetic Resources, Gender and Climate Changes

  1. 1. Participatory Plant Breeding, Biodiversity, Genetic Resources, Gender and Climate Changes<br />s.ceccarelli@cgiar.org<br />
  2. 2. Reduction of biodiversity<br />The Right to Food is the Right to Biodiversity<br />Biodiversity<br />It has been recognized that biodiversity is key to securing global food supply<br />Source Thrupp LA (2000). Linking agricultural biodiversity and food security. The valuable role of agrobiodiversity for sustainable agriculture. Int. Affairs, 76: 265-281<br />Biodiversity<br />75% of genetic diversity of agricultural crops<br />has been lost<br />Report of the Special Rapporteur on the right to food<br />United Nations<br />General Assembly<br />23 July 2009<br />Source International Union for Conservation of Nature (IUCN) <br />Food security<br />Right to Food<br />
  3. 3. Reduction of agro-biodiversity<br />4 varieties<br />4 varieties<br />6 variety<br />75%<br />65%<br />71%<br />Source:<br />World Conservation Monitoring Center, Global Biodiversity<br />6 varieties<br />9 varieties<br />50%<br />50%<br />
  4. 4. The world seed market<br />11%<br />49%<br />33%<br />53%<br />36%<br />17%<br />These are the same<br />
  5. 5. Diversity, Food…… and Health<br /><ul><li>There are approximately 250.000 plant species
  6. 6. 50.000 are edible
  7. 7. 250 are food crops
  8. 8. 90% of the calories in the human diet come from 15 crops and 60% from 3 crops (wheat, rice and maize)
  9. 9. The most widely grown varieties of these three crops are closely related and genetically uniform (pure lines and hybrids)</li></li></ul><li>How did we do that?<br />
  10. 10. The Evolution of Plant Breeding<br /><ul><li>For millennia plant breeding has been done by farmers
  11. 11. Many different farmers in very many places selected for specific adaptation landraces
  12. 12. With the beginning of Genetics plant breeding was taken away from farmers and started being done by very few people in very few places
  13. 13. Breeding for specific adaptation was replaced by breeding for wide adaptation displacement of landraces
  14. 14. ……. and then most plant breeding became private and farmers’ breeding (almost) illegal </li></li></ul><li>Local Knowledge and Diversity<br />
  15. 15. Not only in developing countries<br />
  16. 16. Three Levels of Biodiversity<br /><ul><li>Different Crops</li></li></ul><li>Three Levels of biodiversity<br /><ul><li>Different Crops
  17. 17. Different Varieties within the same crop</li></li></ul><li>Three Levels of biodiversity<br /><ul><li>Different Crops
  18. 18. Different Varieties within the same crop
  19. 19. Heterogeneous Varieties</li></li></ul><li>
  20. 20. Genetic vulnerability<br />The Great Potato famine in Ireland (1845-1849)<br />
  21. 21. Genetic uniformity and vulnerability (UG99)<br />IRAN 2008<br />PAKISTAN 2009<br />
  22. 22. Freezing diversity: from fields to gene banks<br /><ul><li>Gene Banks are very important
  23. 23. Not all has been conserved
  24. 24. They freeze not only seed but also evolution
  25. 25. Must be complemented by in situ conservation</li></li></ul><li>Return to Diversity through Participatory Plant Breeding<br />Can we reconcile biodiversity and food security?<br />
  26. 26. Definitions<br />Decentralization<br />Participation<br />
  27. 27. Decentralization<br />Decentralization = direct selection in the target environment<br />Decentralized selection is not necessarily<br />selection for specific adaptation<br />Fully accepted by professional breeders in some countries (for example Australia)<br />
  28. 28. What is Participatory Plant Breeding?<br />
  29. 29. What is plant breeding and who is a breeder?<br /><ul><li>those scientists who have the full responsibility of a breeding program, made up of subsequent cycles, to develop new cultivars and improved germplasm
  30. 30. those scientists who contribute to crop improvement through breeding research</li></ul>Ransom C, Drake C, Ando K, Olmstead J (2006) Report of breakout group 1: What kind of training do plant breeders need, and how can we most effectively provide that training? HortScience 41, 53–54.<br />
  31. 31. What is Participatory Plant Breeding?<br />Is a dynamic collaboration between Breeding Institutions (National or International) and farmers which exploits their comparative advantages<br />

  108. 108. The International Treaty on Plant Genetic Resources for Food and Agriculture<br />As of November 2008, 120 countries and the European Community are Contracting Parties to the Treaty<br />
  109. 109. Article 6 – Sustainable Useof Plant Genetic Resources<br />6.2 The sustainable use of plant genetic resources for food and agriculture may include such measures as:<br />promoting, as appropriate, plant breeding efforts which, with the participation of farmers, particularly in developing countries, strengthen the capacity to develop varieties particularly adapted to social, economic and ecological conditions, including in marginal areas;<br />
  110. 110. Article 9 – Farmers’ Rights<br />(a) protection of traditional knowledge relevant to plant genetic resources for food and agriculture;<br />(b) the right to equitably participate in sharing benefits arising from the utilization of plant genetic resources for food and agriculture;<br />(c) the right to participate in making decisions, at the national level, on matters related to the conservation and sustainable use of plant genetic resources for food and agriculture.<br />9.3 Nothing in this Article shall be interpreted to limit any rights that farmers have to save, use, exchange and sell farm-saved seed/propagating material, subject to national law and as appropriate.<br />
  111. 111. http://www.srfood.org/<br />
  112. 112. Article 11 of the International Covenant on Economic, Social and Cultural Rights imposes on States three levels of obligations in the realization of the right to food<br /><ul><li>to respect existing access to adequate food

  114. 114. to fulfill the right to food</li></li></ul><li>Recommendations to fulfill these<br />obligations<br /><ul><li>Allow farmers to rely on informal seed systems
  115. 115. Include landraces in the variety lists
  116. 116. Support and scale up local seed exchange systems
  117. 117. Develop incentives to the wider use of food products made out of farmers’ varieties
  118. 118. Ensure the active participation of farmers in decisions related to the conservation and sustainable use of plant genetic resources
  119. 119. Increase the resources allocated to public agricultural research
  120. 120. Put farmers at the centre of research through participatory research schemes such as participatory plant breeding</li></li></ul><li>Conclusions<br />Participatory Research in general and Participatory Plant Breeding in particular can be considered as international<br />public goods: <br />Food security<br />Climatic changes<br />Biodiversity<br />Seed <br />
  121. 121. Conclusions<br />Being a highly decentralized process participatory plant breeding produces varieties which are:<br /><ul><li>Different from country to</li></ul> country<br /><ul><li>Different from village to village</li></ul> within a country<br /><ul><li>Different within the same</li></ul> village<br />
  122. 122. Conclusions<br />Fits crops to the environment rather than modifying the environment, and therefore is ideal for organic conditions <br />
