    Soil-ecological monitoring is a scientific information system for monitoring changes in soil cover, assessing the state of soils, and predicting the impact of natural and anthropogenic factors on them. This monitoring shows the results of undesirable regional and global changes in soil cover and landscape and anthropogenic changes over time. Therefore it is important to study the change in the state of land used for crops in the Mugan Desert, where intensive farming is used and to make timely proposals to resolve these changes. The Mugan Desert is located in the southeastern part of the Kura-Araz lowland. The total area of the Mugan Desert is 455,332.5 ha. The main soils are gray-brown, sierozem-meadow, meadow-sierozem, bog-meadow, and alluvial-meadow soils, which are occupied by crops. These soils were the objects of study of the authors. Soil-ecological monitoring was carried out according to the method of G.V. Dobrovolsky and other scientists. Laboratory analyzes, which were taken from soil samples, were carried out according to generally accepted methods. The authors also collected and processed soil data from stock and literary materials of the period from 1980 to 1985 and the present. The authors found that in three of the four studied soil types over 40 years, an increase in crop-producing power was observed in one - it decreased. The content of humus in gray-brown soils increased by 0.20%, meadow-sierozem - by 0.14%, sierozem-meadow - by 0.12%, and in alluvial-meadow soils the content of humus decreased by 0.17%, nitrogen - by 0.02%, phosphorus - by 0.02%. Based on the analysis, the authors compiled a soil salinity map of the Mugan steppe (M 1: 100,000) and determined that alluvial-meadow soils were mainly subjected to low salinity (+0.19%), gray-brown - medium (+0.29%), meadow-sierozem (+0.67%) and sierozem-meadow soils (+0.44%) - to strong salinity. As a result of comparing our data on soil salinity in the study area with the data of G.Sh. Mamedov (2000), the authors found that the area of saline lands in the Mugan Desert increased from 33.9% to 66.1%, of which the area of weakly saline soils decreased from 24.24% to 10.58%, of moderately saline soils increased from 9.68% to 15.6, and highly saline also increased from 5.33% to 36.4%.Почвенно-экологический мониторинг как научная информационная система контроля изменений почвенного покрова, оценки состояния почв и прогнозирования воздействия на него природных и антропогенных факторов показывает результаты нежелательных региональных и глобальных изменений почвенного покрова и ландшафта, антропогенных изменений во времени. В связи с этим важно изучить изменение состояния земель, используемых под сельскохозяйственными культурами на Муганской равнине, где применяется интенсивное земледелие, и своевременно внести предложения по урегулированию этих изменений. Муганская равнина расположена в юго-восточной части Кура-Аразской низменности, общая площадь которой составляет 455332,5 га. Основными почвами исследуемой территории, занятыми под сельскохозяйственными культурами, являются серо-коричневые, сероземно-луговые, лугово-сероземные, болотно-луговые и аллювиально-луговые. Почвенно-экологический мониторинг проводился по методике Г.В. Добровольского и других ученых, лабораторные анализы взятых почвенных образцов проводились по общепринятым методикам, а также были собраны и обработаны почвенные данные из фондовых и литературных материалов периода 1980–1985 гг. и нынешнего времени. Установлено, что в трех из четырех исследованных типов почв за 40-летний период наблюдалось увеличение плодородия, в одном – его снижение. Содержание гумуса в серо-коричневых почвах увеличилось на 0,20%, лугово-сероземных – на 0,14, сероземно-луговых – на 0,12, а в аллювиально-луговых почвах содержание гумуса уменьшилось на 0,17%, азота – на 0,02, фосфора – на 0,02%. На основе анализа составленной нами карты засоления почв Муганской степи (М 1 : 100000) определено, что аллювиально-луговые почвы в основном подверглись слабому засолению (+0,19%), серо-коричневые – среднему (+0,29%), лугово-сероземные (+0,67%) и сероземно-луговые почвы (+0,44%) – сильному засолению. В результате сравнения собственных данных по засолению почв исследуемой территории с данными Г.Ш. Мамедова (2000 г.) установлено, что площадь засоленных земель на Муганской равнине увеличилась с 33,9 до 66,1%, из них площадь слабозасоленных почв – с 24,24 до 10,58, среднезасоленных – с 9,68 до 15,6, а сильнозасоленных – с 5,33 до 36,4%

    Paleoanthropological research focus still devotes most resources to areas generally known to be fossil rich instead of a strategy that first maps and identifies possible fossil sites in a given region. This leads to the paradoxical task of planning paleontological campaigns without knowing the true extent and likely potential of each fossil site and, hence, how to optimize the investment of time and resources. Yet to answer key questions in hominin evolution, paleoanthropologists must engage in fieldwork that targets substantial temporal and geographical gaps in the fossil record. How can the risk of potentially unsuccessful surveys be minimized, while maximizing the potential for successful surveys?SFRH/BD/122306/2016info:eu-repo/semantics/publishedVersio
