Other causes include environmental degradation In the early years, a relatively high genetic erosion was observed (13.2% p.a.). From the 1950s until the 1980s erosion rates between 0.48 and 4% p.a. were estimated. In the little island of Favignana there was an erosion rate of 12.2% p.a. leading to the extinction of the last wheat landraces of this island. This manifestation of ‘genetic erosion’ 21, is a process the Convention on Biological Diversity now recognises should be minimised 22 and can threaten populations where, for example, dispersal Crop genetic erosion has been a constant concern since the late 1940s, when conservation efforts began in earnest, but it has never been demonstrated by longitudinal data across environments for any major crop in its center of diversity (3, 4, 7 ⇓⇓ – 10).
Estimating past genetic erosion The characteristics Se hela listan på fao.org The BAP-AGRI also highlights the importance of Council Directive 98/95/EC of 14 December 1998 (3 ) which created the legal framework needed to open up the possibility of allowing the marketing of seed of landraces and like varieties, which are naturally adapted to the local and regional conditions and threatened by genetic erosion, with the aim of contributing to in situ conservation.

Teklu2 Abstract Plant Genetic Resources (PGR) continue to play an important role in the development of agriculture. The following aspects receive a special consideration: 1. Definition. The term was coined in 1970. The genepool concept Genetic erosion gets worse We get hours of amusement from poking holes in the many ways in which statements about the loss of 75% of agricultural biodiversity are likely to be less than accurate any way you slice them.

Gradual loss of genes or genetic erosion leaves our species of plants and animals vulnerable to new environmental and biotic challenges and causes heavy damage to the society. The Irish Potato famine was a dramatic example of the dangers of genetic uniformity.

genetic erosion — European Environment Agency Genetic erosion is a process whereby an already limited gene pool of an endangered species of plant or animal diminishes even more when individuals from the surviving population die off without getting a chance to meet and breed with others in their endangered low population. Genetic erosion is the loss of genetic diversity—often magnified or accelerated by human activities.
en Plant genetic resources will be considered as being under threat of genetic erosion on condition that sufficient evidence of genetic erosion, based upon scientific results or indicators for the reduction of landraces/primitive local varieties, their population diversity and, where relevant, for modifications in the prevailing agricultural practices at local level, is described and included

The major driving forces behind genetic erosion in crops are: variety replacement, land clearing, overexploitation of species, population pressure, environmental degradation, overgrazing, policy and changing agricultural systems.
