No Thumbnail AvailableBook (series)Technical studyGenetic resources of common carp at the Fish Culture Research Institute Szarvas, Hungary 2001
Also available in:
No results found.The genetic resources of common carp maintained at the Fish Culture Research Institute in Szarvas, Hungary, are described. Eighteen Hungarian strains (landraces) and 13 strains from outside Hungary (primarily former Soviet Republics, Eastern Europe and Asia) are maintained in a living gene bank at the Institute. The genetic improvement of common carp in Hungary started in 1962 at the Fish Culture Research Institute. Traditional selection (family and mass selection), other types of genetic mani pulations, such as inbreeding, gynogenesis and hormonal sex-reversion, and intra-specific hybridization have resulted in the production and testing of more than 150 combinations of common carp strains. Five main features were evaluated that determined the economical value of the resulting strains: survival, weight gain, feed conversion ratio, slaughter value and fat content of the meat. These research efforts produced three outstanding hybrids of common carp: the Sz215 mirror, the SzP31 and SzP3 4 scaly hybrids, which now represent 80 percent of the total carp production in Hungary. The Fish Culture Research Institute is a key part of a national breeding programme in Hungary that provides fish farms and fish seed production units with parental lines of hybrid common carp. -
Book (stand-alone)BulletinForest Genetic Resources No. 25 1997The present issue of Forest Genetic Resources (FGR) goes to press immediately following the Eleventh World Forestry Congress held in Turkey 13-22 October 1997, which more than 4000 colleagues from 145 countries attended. In regard to the conservation and use of forest genetic resources, the Congress, in its deliberations and report, stressed that action to conserve, manage, sustainably utilize and enhance forest genetic resources is an urgent priority. The lead article in the present issue, whil e focusing on temperate conifers, will provide guidance in the development of in situ strategies also in other ecological zones. In addition, FGR No. 25 includes a number of additional notes and articles from colleagues in all regions of the world.

Book (stand-alone)Flagship2015–16年农产品市场状况
贸易与粮食安全：更好地平衡国家重点与集体利益
2015全球农产品和粮食产品贸易已在最近几十年取得快速增长，各国作为出口或进口方越来越多地参与这一贸易进程。这种趋势预计将在今后几十年中持续。因此，贸易将在全球各区域对粮食安全的程度和性质产生越来越重要的影响。我们面临的挑战就是确保农产品贸易的扩大能对消除饥饿、粮食不安全和营养不良起到促进作用，而不是阻碍作用。 本版《农产品市场状况》旨在缓解目前各方在农产品贸易对粮食安全产生的影响以及如何管理农产品贸易以确保贸易开放度的增加能惠及所有国家等问题上出现的观点两极分化现象。本书通过就一系列话题举证和说明，努力促成各方就政策选择开展有实证依据的辩论，并在政策选择过程中努力实现必要的改进。 -
IndexesLibrary Classified Catalogue (1)/ Bibliothèque de catalogues systématiques (1) 1948
Also available in:
No results found.The Protocol of 8-9 July 1946 relative to the dissolution of the International Institute of Agriculture, transferred the functions and assets of the said Institute to FAO. Of these assets, the Library is unquestionably the most outstanding and is a lasting record of the Institute's work and its achievement in the field of agriculture. This catalogue will undoubtedly contribute towards a better knowledge of this international Library. This volume in its present form, represents the systematic card-index, by subject of the Brussels Decimal Classification, in French and English, and it's supplemented by the general alphabetical index of authors.
This is Part 1 of 4 - Books - sections General, Bibliographies, Periodicals, Philosophy and Social Sciences.

No Thumbnail AvailableBook (stand-alone)Training materialPlanning in government forest agencies how to balance forest use and conservation: agenda for training workshop. 1998
Also available in:
No results found.The purpose of planning for forestry development is to establish a workable framework for forest use and conservation which incorporates the economic, social and environmental dimensions on a sustainable basis. The framework is about creating a shared vision of how forests will be used and protected. This can be summed up in a single central question: Trees and forests for whom and for what? The question is not new but what is new is the perception that so many different groups have an interest in the reply. Forestry planning has traditionally been mainly concerned with the production of timber for industry and other wood products, and with forest industry development. Planning for environmental goals also has a long history but was largely restricted to designated areas for exclusive conservation. National forestry development agencies were essentially responsible for the sustained yield management on protected public forest lands and for reserved forests. The term "sustained yield " was mostly limited to wood production and therefore excluded the majority of other forest products and services. Although most forestry agencies have made progress towards multiple-use management, planning remains often biased towards timber in a wide range of countries. Many of the actions taken in order to stimulate forestry development in the immediate failed to sustain the momentum of growth in the longer term. Short term achievements sometimes resulted in degradation or destruction of the stock of natural capital needed in order to maintain growth in the future or reduced options for future end uses by degrading the forest capital.
