Förlagets beskrivning
Genetic erosion, that is, the loss of native plant and genetic diversity
has been exponential from the Mediterranean Basin through the 20th century.
This careless eradication of species and genetic diversity as a result of human
activities from a "hot-spot" of diversity threatens sustainable agriculture and
food security for the temperate regions of the world. Since the early 1900s
there has been a largely ad hoc movement to halt the loss of plant diversity
and enhance its utilization. The Convention on Biological Diversity and Food
and Agriculture Organization of the United Nations International Undertaking on
Plant Genetic Resources, both highlight the need to improve conservation
methodologies and enhance utilisation techniques. It has been argued that the
most important component of biodiversity is the genetic diversity of crop and
forage species used to feed humans and livestock. These cultivated and related
wild species provides the raw material for further selection and
improvement. Leguminosae species are of major economic importance (peas, chickpeas,
lentils and faba beans, as well as numerous forage species) and provide a
particularly rich source of protein for human and animal foods. Their
distribution is concentrated in the Mediterranean region and therefore the
improvement of their conservation and use in the region is critical. This text
is designed to help ensure an adequate breadth of legume diversity is conserved
and to help maximize the use of that conserved diversity. The subjects of
conservation and use of legume diversity, the Mediterranean ecosystem and
taxonomy of legumes are introduced. Generic reviews of the taxonomy, centre of
diversity, ecogeographic distribution, genetic diversity distribution,
conservation status, conservation gaps and future research needs are provided,
along with a discussion of the importance of rhizobia to the maintenance of
legume diversity. Current ex situ and in situ conservation activities as well
current legume uses are reviewed. In conclusion future priorities for ex situ
and in situ plant genetic conservation and use of Mediterranean legumes are
highlighted. All contributors look forward rather than simply reviewing past and current
activities and therefore it is hoped that the identification of genetic
erosion, location of taxonomic and genetic diversity and promotion of more
efficient utilization of conserved material will be enhanced. Genetic erosion, the loss of native plant and genetic diversity, has been
exponential from the Mediterranean Basin through the 20th century. This text is
designed to help ensure an adequate breadth of legume diversity is conserved
and to help maximize the use of that conserved diversity.
