The state of the world’s crop biodiversity
This is a big one from the FAO. The Second Report on the State of the World’s Plant Genetic Resources for Food and Agriculture is a mega tome. At just under 400 pages, this very dense report is packed into eight chapters which occupy half the pages. The other half is made up of annexures and appendices. Even then, it’s just part of the entire SOWPGR2 package, for there is a synthesis report, the Global Plan of Action for the Conservation and Sustainable Utilization of Plant Genetic Resources, there is a thematic background studies section with seven studies, there are the country reports (over 100!) and there is a picture gallery. It’s an entire curriculum.
It’s been a while coming – the first report was published by FAO 14 years ago and much has changed since then. For one thing, climate change was quite uncommon in common discourse. This is hugely important because the genetic diversity of the grains, legumes, vegetables and fruits that we grow and eat – referred to as plant genetic resources for food and agriculture, or PGRFA – are the foundation of food production, and the biological basis for food security, livelihoods and economic development.
The synthesis report says that PGRFA are crucial for helping farmers adapt to current and future challenges, including the effects of climate change. FAO’s Second Report on the State of the World’s Plant Genetic Resources for Food and Agriculture provides a comprehensive overview of recent trends in PGRFA conservation and use around the world.
It is based on information gathered from more than 100 countries, as well as from regional and international research and support organizations and academic programmes. The report documents the current status of plant genetic resources diversity, conservation and use, as well as the extent and role of national, regional and international efforts that underpin the contributions of PGRFA to food security. It highlights the most significant changes that have occurred in the sector since 1996, as well as the gaps and needs that remain for setting future priorities.
The core messages:
• PGRFA are essential raw materials for helping farmers respond to climate change. Plant breeding capacity needs to be strengthened and breeding programmes must be expanded to develop varieties with traits needed to meet this challenge.
• Loss of PGRFA has reduced options for the agricultural sector. The major causes of genetic erosion are land clearing, population pressures, overgrazing, environmental degradation and changing agricultural practices.
• Local PGRFA diversity found in farmers’ fields or in situ is still largely inadequately documented and managed. There is now a growing awareness of the importance of this diversity and its contribution to local food security.
• There has been progress in securing PGRFA diversity in a larger number of national genebanks. However, much of the diversity, particularly of crop wild relatives (CWR) and underused species relevant for food and agriculture, still needs to be secured for present and future use.
• Rapid scientific advances, especially in information technology and molecular biology, have introduced new techniques for PGRFA conservation and use. Their wider application offers new opportunities to increase efficiency of the conservation–production chain.
• Significant policy developments have changed the landscape of PGRFA management. Many more countries have adopted national programmes, laws and regulations for biodiversity following the adoption of the Convention on Biological Diversity (CBD) and the International Treaty on Plant Genetic Resources for Food and Agriculture (ITPGRFA).
• Better communication, collaboration and partnerships are needed among institutions dealing with PGRFA management – from conservation to plant breeding and seed systems. These are the key factors for an integrated conservation and utilization strategy and delivering sustainable solutions to build a world without hunger.
