In Turkey, studies devoted to conservation of animal genetic resources are carried out by general directorate of agricultural research (TAGEM) under the ministry of food, agriculture and livestock. There are 9 sheep and 3 goat breeds and 3 silkworm lines which produce animal fiber have been put under conservation by TAGEM since 1996. A considerable amount of these genotypcs are preserved as in situ. The success of this conservation method is directly associated with economically making the best of these genotypes which are preserved. Hence, making the most of fiber production alongside meat and milk production would make a great contribution to their conservation. For this purpose, determining production biology of mohair and textile features of Ankara goats at present, determining all features of traditional items (especially handicrafts) made of fibers obtained from these breeds and lines which have been put under protection and creating new usage areas have been issues worked upon. Along with this, in recent years, just as the world, especially EU countries, interests and studies for issues such as organic animal fiber production, rural development and geographical indications have been increasing in Turkey, as well. In the near future, this situation is supposed to have a great effect on increasing of animal fiber production in a positive way, too. Hence, to benefit more effectively from fibers obtained from these breeds which have been put under protection will make a great contribution to be protected by breeders. For this purpose, there will be studies in the near future devoted to determining production biology of fiber and determining features of textile in breeds and lines and increasing the consumption of products to be obtained from these fibers as well as Ankara goats. Therefore, in this article, it was emphasized on the more efficient of ways to be benefited from fiber production in these breeds and lines under protected. 展开更多

People and nature are working in tandem to reduce the integrity of traditional agricultural systems. The paper highlighted the drivers of change acting on traditional agricultural landscapes including the threats and barriers hindering biodiversity conservation. The drivers of change are: modem agriculture, tourism, education and outmigration and climate change. The threats are encroachment and land-use change, pollution, replacement of traditional varieties and erosion of indigenous knowledge systems and practices. The barriers to biodiversity conservation include the incapacity of farmers to respond to pressures affecting their traditional farming systems, absence of methodologies for integrating traditional and modem knowledge in biodiversity conservation and the multi-functionality of traditional agriculture not fully captured by the market. The conservation framework to guide stakeholders for in-situ management of biodiversity includes niche market development, revenue generation and cultural restoration. The study made use of data collected during the series of workshops conducted in 2005-2007 covering the Ifugao Rice Terraces of the Philippines. Secondary data from other traditional agricultural systems were integrated to enrich the discussion and write-up of this paper. 展开更多
