Genes in the Field: Conserving Plant Diversity on Farms is a comprehensive collection of papers focusing on agricultural conservation and diversity issues throughout the world. Recently, regional and local farm seed variety has been reduced because of increased population, agricultural science and technology and the integration of the world's many diverse cultures. Because of this, diversity on individual farms across wide regions is threatened by modern crop varieties that have been bred for broad adaptation, resistance to disease, and other risk factors such as their ability to better use water, fertilizer, and higher yields. The concern of the farmers to maintain production levels and income often seems incompatible with those whose focus is on the maintenance of viable and sustainable ecosystems and maintaining genetic diversity. Exploring and understanding these different concerns is an essential starting point for answering some of the key questions about the implementation of "on farm" conservation and the role of local cultivators in sustainable development.

This anchor volume to the series Managing Global Genetic Resources examines the structure that underlies efforts to preserve genetic material, including the worldwide network of genetic collections; the role of biotechnology; and a host of issues that surround management and use. Among the topics explored are in situ versus ex situ conservation, management of very large collections of genetic material, problems of quarantine, the controversy over ownership or copyright of genetic material, and more.

The recent development of ideas on biodiversity conservation was already being considered almost three-quarters of a century ago for crop plants and the wild species related to them, by the Russian geneticist N.!. Vavilov. He was undoubtedly the first scientist to understand the impor tance for humankind of conserving for utilization the genetic diversity of our ancient crop plants and their wild relatives from their centres of diversity. His collections showed various traits of adaptation to environ mental extremes and biotypes of crop diseases and pests which were unknown to most plant breeders in the first quarter of the twentieth cen tury. Later, in the 1940s-1960s scientists began to realize that the pool of genetic diversity known to Vavilov and his colleagues was beginning to disappear. Through the replacement of the old, primitive and highly diverse land races by uniform modem varieties created by plant breed ers, the crop gene pool was being eroded. The genetic diversity of wild species was equally being threatened by human activities: over-exploita tion, habitat destruction or fragmentation, competition resulting from the introduction of alien species or varieties, changes and intensification of land use, environmental pollution and possible climate change.

Over the past decade the importance of natural resources for sustainable agricultural development has been increasingly discussed at international forums and conferences. Aside from the sustainable management of soil, water, and air, it now seems to be accepted that the sustainable management of genetic resources is one of the four indispensable preconditions for a sustainable agriculture. The discussion on conservation of plant genetic resources for food and agriculture (PGRFA), however, has to reflect the costs of conservation as well. These have not yet been discussed intensively. The study analyzes the conservation costs of plant genetic resources; it also assesses the effectiveness of conservation and the efficiency of the different conservation instruments. It is based on extensive surveys in relevant countries. Following the detailed cost and impact analysis, the results show that the effectiveness of conservation strategies may be increased.

The papers included in this Special Issue address a variety of important aspects of plant biodiversity and genetic resources, including definitions, descriptions, and illustrations of different components and their value for food and nutrition security, breeding, and environmental services. Furthermore, comprehensive information is provided regarding conservation approaches and techniques for plant genetic resources, policy aspects, and results of biological, genetic, morphological, economic, social, and breeding-related research activities. The complexity and vulnerability of (plant) biodiversity and its inherent genetic resources, as an integral part of the contextual ecosystem and the human web of life, are clearly demonstrated in this Special Issue, and for several encountered problems and constraints, possible approaches or solutions are presented to overcome these.

The book reflects the work in progress regarding the analysis of the costs of crop genetic resources conservation that has been conducted at various research insti tutes over the last couple of years, including research conducted at ZEF and asso ciated institutes. In addition, contributions in this publication were presented at a special session during the "Global Dialogue: The Role of the Village in the 2]'1 Century: Crops, Jobs and Livelihood" in Hannover, Germany, at the World Exposition in Au gust 2000. The purpose of the publication is to make a general contribution to the ongoing discussion about the conservation of crop genetic resources as part of the global strategy to secure increasing food production in a sustainable way. Specifically, it discusses the costs of the worldwide efforts to conserve crop genetic resources on the basis of theoretical and applied studies. It aims to serve decision-makers at dif ferent levels with information on the costs involved in the conservation of genetic resources and hence to increase the awareness of the importance of improving the cost effectiveness of different conservation methods in order to optimize the sus tainability of conservation. The quoted Leipzig Declaration, which was adopted at the Fourth International Technical Conference on Plant Genetic Resources in Leipzig in June 1996, dem onstrates the close linkage of the contributions to the ongoing discussion about the implementation of the Global Plan of Actionfor the Conservation and Sustainable Utili zation of Plant Genetic Resources for Food and Agriculture.

It is a distressing truism that the human race during the last millennium has caused the exponential loss of plant genetic diversity throughout the world. This has had direct and negative economic, political and social consequences for the human race, which at the same time has failed to exploit fully the positive benefits that might result from conserving and exploiting the world's plant genetic resources. However, a strong movement to halt this loss of plant diversity and enhance its utilisation for the benefit of all humanity has been underway since the 1960's (Frankel and Bennett, 1970; Frankel and Hawkes, 1975). This initiative was taken up by the Convention on Biological Diversity (CBD, 1992) that not only expounds the need to conserve biological diversity but links conservation to exploitation and development for the benefit of all. Article 8 of the Convention clearly states the need to develop more effective and efficient guidelines to conserve biological diversity, while Article 9, along with the FAO International Undertaking on Plant Genetic Resources, promotes the adoption of a complementary approach to conservation that incorporates both ex situ and in situ techniques.
