Dulloo² ¹ Centre for Plant Diversity and Systematics, School of Plant Sciences, The University of Reading, Reading RG6 6AS, UK ² International Plant Genetic Resources Institute, via dei Tre Denari 472/a, 00057 Maccarese, Rome, Italy The International Plant Genetic Resources Institute (IPGRI) is an independent international scientific organization that seeks to improve the well-being of present and future generations of people by enhancing conservation and the deployment of agricultural biodiversity on farms and in forests. It is one of 15 Future Harvest Centres supported by the Consultative Group on International Agricultural Research (CGIAR), an association of public and private members who support efforts to mobilize cutting-edge science to reduce hunger and poverty, improve human nutrition and health, and protect the environment. IPGRI has its headquarters in Maccarese, near Rome, Italy, with offices in more than 20 other countries worldwide. The Institute operates through four programmes: Diversity for Livelihoods, Understanding and Managing Biodiversity, Global Partnerships, and Improving Livelihoods in Commodity-based Systems. The international status of IPGRI is conferred under an Establishment Agreement which, by January 2005, had been signed by the Governments of Algeria, Australia, Belgium, Benin, Bolivia, Brazil, Burkina Faso, Cameroon, Chile, China, Congo, Costa Rica, Côte d’Ivoire, Cyprus, Czech Republic, Denmark, Ecuador, Egypt, Greece, Guinea, Hungary, India, Indonesia, Iran, Israel, Italy, Jordan, Kenya, Malaysia, Mauritania, Morocco, Norway, Pakistan, Panama, Peru, Poland, Portugal, Romania, Russia, Senegal, Slovakia, Sudan, Switzerland, Syria, Tunisia, Turkey, Uganda and Ukraine. Financial support for IPGRI’s research is provided by more than 150 donors, including governments, private foundations and international organizations.

Each title will aim to provide guidance on choices while implementing conservation techniques and procedures and in the experimentation required to adapt these to local operating conditions and target species. Techniques are discussed and, where relevant, options presented and suggestions made for experiments. The Technical Bulletins are authored by scientists working in the genetic resources area. IPGRI welcomes suggestions of topics for future volumes. In addition, IPGRI would encourage, and is prepared to support, the exchange of research findings obtained at the various genebanks and laboratories.

They form the backbone of Earth’s ecosystems and provide a wide range of ecosystem goods and services. The benefits they provide include food, medicines, genetic material for crop improvement, clothing and shelter, and they have great economic and cultural value. They thus make an important contribution to human well-being. Over the last hundred years the trends observed in the loss of plant biodiversity have been a matter of great concern. Despite all the efforts made to conserve plant diversity, the situation today is still very alarming. Up to one-quarter of the estimated 400 000 species of plants are believed to be threatened worldwide. The Convention on Biological Diversity (CBD), which came into force in December 1993, has been the major global instrument to rally world-wide efforts for the effective conservation of biological diversity. It calls for mechanisms to be put in place for both in situ and ex situ conservation (see Articles 8 and 9). A Global Strategy for Plant Conservation (GSPC) has subsequently been developed and was adopted at the Sixth Meeting of the Conference of Parties to the CBD held in The Hague in April 2002 (Decision VI/9). This strategy provides an innovative framework of 16 outcome-oriented targets aimed at achieving a series of measurable targets by 2010, of which targets 7, 8 and 9 relate to in situ and ex situ conservation of target species. Target 7 of the GSPC calls for “60% of the world’s threatened species to be conserved in situ”. This is taken to mean that populations of the species are effectively conserved in protected areas or through other in situ management measures.
