Digital agriculture informational resources in local and international databases

The article reviews informational resources on precision and digital agriculture in international cross-disciplinal and sectoral international and local databases. The databases Web of Science, Scopus, AGRIS (by FAO UN) and Engineering infrastructure of Agriculture, Rosinformagrotech, AGROS (by Central Scientific Agricultural Library) with the retrieval requests “Digital agriculture”, “Precision Agriculture” were analyzed. The authors estimated the dynamics of document flows to the AGROS database and confirmed strong growth of volume of local publications on precision agriculture to the level demonstrating technology adoption of precision agriculture. Meanwhile the level of document flow on digital agriculture is at the starting level. Analysis of most frequent publications on the topic showed that there’s no local specialized journals on precision agriculture, most frequently publications appeared in local journals such as “Machinery and equipment for rural areas”, “Soil science and agrochemistry”, “Agricultural machinery and technology”. Predominantly materials were published in specialized foreign journals “Computers and electronics in agriculture” and “Precision agriculture”. Most of the documents were obtained from WOS and Scopus databases, but a lot of them are irrelevant. While searching for foreign documents it makes sense to use all the databases available, but most of the full-size texts in open access are available in the AGRIS database. In the same way AGROS database provide a wide range of full-size texts in the Russian language. Both AGROS and AGRIS databases showed high efficiency of search with most relevant documents in search results since both databases use thesaurus as a linguistic tool

Общеотраслевые лингвистические средства: роль в информационном обеспечении научных исследований агропромышленного комплекса России

The studies were accomplished at the Central Scientific Agricultural Library (CSAL) to update the industry-wide linguistic instruments used in the Library’s Information Retrieval System and union catalog of the research institutions’ libraries of the Agroindustrial Complex (AIC) of Russia. The set of linguistic tools is briefly described; the two-level model of the linguistic support structure is introduced. The significance and advantages of using information retrieval languages in the Automated Information-Retrieval System are discussed. The purpose of the study was to improve the information support of research in the AIC in terms of actualization of the database (BD) of the Information Retrieval Thesaurus in Agriculture and Food and the database “Authority File (AF) of Scientific Research Institutions (SRI) in the AIC”. Brief descriptions of these information retrieval languages and their functions are included. The functions of the Information-Search Thesaurus are: to index documents and inquiries; to reflect the paradigmatic relations between lexical units; to control and normalize lexis in agriculture and food; to provide unified and formalized information representation in AGROS database; to expand automatically document search profiles; it also functions as a terminological guide in agriculture and food. As the guide, it retrieves the names of institutions since the foundations date; it can be also used for constructing the bibliographic record element (organization’s name. or corporate author); and retrieves information from information resources. The procedures for adding new lexical items and revising the previously included data are described.Рассмотрены исследования, проведённые в Центральной научной сельскохозяйственной библиотеке по актуализации общеотраслевых лингвистических средств, используемых в информационно-поисковой системе библиотеки и сводном каталоге библиотек научно-исследовательских учреждений АПК России.

Информационное обеспечение научных исследований по проблематике АПК

The Central Scientific Agricultural Library’s system of the agrarian science information support is examined. The Library strives to make the content available online to the maximum. Most of its information services are offered both in conventional and online formats. For the recent 26 years the Library’s products have been being generated in digital formats and are accessible via the Library’s www-site in a varying degree. The www-site serves as a billboard promoting the Library’s events and activities, as well as the reading environment for the users retrieving information. The system of agrarian researcher awareness-building includes alert informing, current informing, and selective dissemination of information. The main information source is the CSAL collection comprising above 3 millions of depository items. On this basis of information products are generated: bibliographic, abstract and full-text databases, bibliographic and abstract publications, and electronic libraries. The key information product is the AGROS database comprising information on books and articles in 42 languages of the world of the total volume of over 1.95 million records. The database provides efficient identifying and subject-specific search owing to target- developed information retrieval languages: the information retrieval thesaurus in agriculture and foods, RUSMARC format. The authors conclude that agrarian science information support comprises diverse information products; well-developed awareness-building system enables to receive information in print and digital formats, online or in the Library’s physical premises, independently or through librarian’s assistance.Рассмотрена функционирующая в Центральной научной сельскохозяйственной библиотеке система информационного обеспечения аграрной науки.

Scientific heritage of belarusian agrarian science in the information products of the CSAL

<p>The article presents the results of the analysis of publications of Belarusian scientists from the collection of the Central Scientific Agricultural Library, presented in the card complex-system catalog (CSC) and the AGROS database. In the era of card catalogs, the CSC was notable for its uniqueness, as it combines the best qualities of subject and systematic catalogs. The CSC reveals the problem taken as a whole, collecting in one place all the information on the subject, book and article material, which is convenient for a user. The publications included in the heading "Belarus" of the geographical section of the CSC were analyzed. The CSC was mothballed in 2000 and is only used for retrospective searches. The current document flow (since 1992) is reflected in the electronic catalog and the AGROS polythematic database. The bibliometric analysis of publications on agricultural issues by Belarusian authors presented in the AGROS database was carried out.</p&gt

Interglacial History of a Palaeo-lake and Regional Environment: A Multi-proxy Study of a Permafrost Deposit from Bolshoy Lyakhovsky Island, Arctic Siberia

Chironomid, pollen, and rhizopod records from a permafrost sequence at the Bolshoy Lyakhovsky Island (New Siberian Archipelago) document the evolution of a thermokarst palaeo-lake and environmental conditions in the region during the Last Interglacial (MIS 5e, ca. 130120 ka). Open Poaceae and Artemisia associations dominated vegetation at the beginning of the interglacial period, ca. 130 ka. Rare shrub thickets (Salix, Betula nana, Alnus fruticosa) grew in more protected and wetter places as well. Saalian ice wedges started to melt during this time, resulting in the formation of an initial thermokarst water body. The high percentage of semi-aquatic chironomids suggests that a peatland-pool palaeo-biotope existed at the site, when initial water body started to form. A distinct decrease in semi-aquatic chironomid taxa and an increase in lacustrine ones point to a gradual pooling of water in basin, which could in turn create thaw a permanent pond during the subsequent period. The highest relative abundance of Chironomus and Procladius reflects an existence of unfrozen water remaining under the ice throughout the ice-covered period during the later stage of palaeo-lake development. Chironomid record points to three successive stages during the water body evolution: (1) a peatland pool; (2) a pond (i.e., less deep than the maximum ice-cover thickness); and (3) a shallow lake (i.e., more deep than the maximum ice-cover thickness). The evolutionary trend of palaeo-lake points to intensive thermokarst processes occurring in the region during the Last Interglacial. Shrub tundra communities with Alnus fruticosa, Betula nana dominated the vegetation during the interglacial optimum that is evidenced by pollen record. The climate was relatively moist and warm. The results of this study suggest that quantitative chironomid-based temperature reconstructions from the Arctic thermokarst ponds/lakes may be problematic owing to other key environmental factors, such as prolonged periods of winter anoxia and local hydrological/geomorphological processes, controlling the chironomid assemblage
