The paper evaluates the climatic conditions in order to organize the restoration of protective forest strips on the territory of the Pervomaysky district of the Republic of Crimea. The following indicators were analyzed and mapped: the wind regime of the territory (wind direction, speed, repeatability); heat and moisture availability of the territory (precipitation for various periods, average and total temperature values for months and periods, moisture coefficients of the territory (Selyaninov hydrothermal coefficient (SCC), Budyko dryness index and Sukachev coefficient (CS). On their basis, climatopes of forest belts are compiled. The presented data and certain climatic parameters are used to determine the design features of forest belts within the areas under consideration. The amount of data provided is sufficient in accordance with the guidelines for the design of protective forest stands to assess the meso-climatic conditions of the survey area.

The conditions for the development of wind erosion are determined by the soil and climatic conditions as well as by the presence or absence of wind barriers. It is because of its climatic and soil conditions that the territory of the South Moravia Region has been affected by erosion for centuries. Combined with the atmospheric conditions, the dry and warm climate enables the development of aeolian processes both in light, drying soils and – under certain climatic conditions – in heavy, clay-loam soils. Soil erosion exposure maps have been prepared in order to identify the territories which are potentially exposed to wind erosion in terms of the soil and climatic conditions. Six exposure categories have been applied to the soils. However, the impact of permanent vegetation barriers – line elements – must be considered in order to identify the most exposed areas. Protective forest belts were planted in the 1950s to counter the effects of wind erosion and they are included in the database of the Institute for Economic Forest Management. The network of these wind barriers and the heath condition of the individual elements are often unsatisfactory because of poor maintenance. The purpose of the study was to evaluate the spatial function of the network of protective forest belts using the map of the potential exposure of soil in the Region of South Moravia. The method used to evaluate the spatial function of the windbreaks presented in the study using GIS instruments.

This article presents the results of studying the plant introduction and the possibility of cultivation of Persian shallot – Allium stipitatum Regel. This plant is popularly used in pickled and salt form for the preparation of various salads, because of which it is classified as an endangered species and is listed in the Red Data Book of the Republic of Tajikistan. Studies on the seed productivity of domesticated Persian shallot were carried out in 2017- 2019 on the territory of experimental plots of the National Republican Center of the Genetic Resources of the Tajik Academy of Agricultural Sciences (Gissar Valley), which is located in the northern part of Rudaki district at an altitude of 730 m above sea level. It was established that the average number of fruits is 250 ± 15.7 pcs; the number of fruit set is 210 pcs; the total number of seeds is 809 pcs per fruit. When compared with the natural growing conditions (Gajne area), it turned out that the seed productivity of Persian shallot under natural conditions is averagely 16.7% - 24.5% higher than in the Rudaki district (Gissar Valley). As a result of the studies, it was found that it is necessary to choose areas with natural protection from sunlight (protective forest belts or stool beds) to create more favorable conditions in the first years of adaptation of Persian shallot in the Rudaki district.

В России большинство автомобильных и железных дорог защищены лесными полосами. В настоящее время в засушливых условиях Ростовской области не уделяется должного внимания научным разработкам по вопросам создания, содержания и реконструкции защитных лесонасаждений  вдоль автомобильных дорог. Целью работы является анализ состояния придорожных защитных лесонасаждений и совершенствование технологических аспектов их создания на примере участка автомагистрали г. Новочеркасск – пос. Каменоломни Ростовской области. Мониторинг придорожных защитных лесонасаждений выявил, что в степных условиях со сложным орографическим рельефом, наряду с защитой от снежных завалов одной из важных функций является эстетическое оформление местности. Протяженность защитных лесных насаждений, как объекта исследований и озеленения – 17 800 м. Маршрут относится к одной из главных магистралей на г. Шахты и федеральную трассу М4 Ростовской области. Определение потребности в создании придорожных лесных полос выявлялось с использованием GPS-навигатора  (GPSmap 62s). Проведен анализ состояния придорожных защитных лесонасаждений на рассматриваемом отрезке автомагистрали и установлен их видовой состав. В соответствии с почвенно-климатическим условиям обоснован ассортимент растений с предпочтением устойчивости к снеголому, декоративности, успешности защиты автодороги от заноса снегом и пылью. Определены объемы посадочного материала с участием Quercus  robur, Acer  platanoides, обоснована система подготовки почвы, видовой состав, схема размещения. На всей протяженности исследуемого участка (17,8 км) требуется создать защитные лесонасаждения (4 лесные полосы протяжённостью 998,0 м, шириной – 12,0 м, площадь 1,2 га). С научным обеспечением и учетом региональных особенностей создания защитных лесонасаждений вдоль автомобильных дорог (конструкция насаждений, ассортимент, методы выращивания, лесоводственные уходы и др.) они способны выполнять свои функции в полном объеме к возрасту 25 лет. In Russia, most roads and railways are protected by forest belts. Even a single row of trees provides good results in road surface protection from snow. At present, in the dry conditions of the Rostov region is not given due attention to scientific developments on the creation, maintenance and reconstruction of protective forests motor roads. The goal of this work (publication) is to analyze the state of roadside protective forest plantations and improve their creation on the example part of the highway of Novocherkassk - Kamenolomni of Rostov region. Monitoring of roadside defensive forests showed that in a steppe environment with complex orographic relief, along with protection from snow clogging, one of the important functions is the aesthetic design of the terrain. The length of protective forest plantations as a research and planting site is 17 800 m. The route is one of the main thoroughfares to the city of Shakhty and the federal highway M4 of the Rostov region. Determination of the need for creating roadside forest belts was detected using GPS-navigator (GPSmap 62s). The condition of roadside protective forest stands on the considered segment of the motorway and their species composition is established. In accordance, with soil and climatic conditions, an assortment of plants with a preference for resistance to snow, decorativeness, and the success of road protection against snow and dust drift are justified. The volumes of planting material with the participation of Quercus   robur, Acer  platanoides, are determined, the soil preparation system, the species composition  and layout. Over the entire length of the investigated area (17,8 km), it is required to create protective forest stands (4 forest belts with a length of 998 m, a width of 12,0 m, an area of 1,2 hectares). With scientific support and consideration of regional peculiarities, creation of protective afforestations along highways (design of plantations, assortment, methods of cultivation, silvicultural care, etc.), they are able to perform their functions in full by the age of 25 years.

A growth in the number of deer and an increase in their productivity are closely related to the solution of the complex problem of reproduction and rational use of deer females. Significant damage to reindeer husbandry is caused by the barrenness of northern domestic deer, the level of which has been quite high in recent years. So, in the Republic of Sakha, on 01.01.2020, the number of domesticated reindeer was 152,068, of which female deer and heifers — 71,818, offspring per 100 females — 59, business yield amounted to 52 fawns per 100 females. The causes of infertility are very diverse, as the natural and climatic conditions of the breeding zones have a significant influence on the reproductive function of reindeer. In Yakutia, the main population of northern domestic deer is bred in mountain taiga and tundra natural-climatic zones, so there are about 55 thousand deer in the mountain taiga zone and more than 65 thousand deer in the tundra zone. In this regard, the study of the peculiarities of the postpartum period course in domestic reindeer females, its morphophysiology, and behavioral reactions depending on the natural and climatic conditions of breeding is of great importance.

The article notes that the growing popularity of healthy lifestyles contributes to the increase in consumption of fruits and berries. At the same time, the analysis of the dynamics of the gardening industry for 2000-2018 shows that the problem of providing fresh fruits and berries to the population remains one of the most important. Based on actual data, linear and logarithmic models of time series of key industry indicators for the period 2010 – 2019 have been compiled. Calculations showed that in the Russian Federation as a whole the trend of reduction of sown areas of perennial fruit plantations will continue with growth of yield and gross fees. In this regard, the issues of distribution and introduction of gardens of intensive type are updated. An overview of the views of domestic scientists-gardeners on the concept of “intensive garden” is given. It has been established that the distribution of intensive gardens is possible only if there are favorable natural and climatic conditions and a developed scientific and production base of nursery management. The current state and problems of gardening in one of the leading regions – the Republic of Dagestan - are considered. A significant technological lag of region in the further development of intensive horticulture has been identified. Various directions of intensification process in horticulture as the main and necessary condition of growth of efficient and sustainable production are summarized.

The Republic of Croatia has a long tradition of fruit growing due to its geographical location, climatic conditions, and high quality of fruit crops, especially apple fruits. Apples can be used for the formulation of functional foods either in processed form (e.g., juice), or as a by-product (e.g., apple pomace). However, there is a growing demand for functional foods derived from ancient and traditional plant sources as they are recognized as a very valuable source of health-promoting bioactive ingredients. Similarly, old apple cultivars (Malus domestica Borkh.) are characterized by good morphological and pomological properties, less need for chemicals during cultivation and the higher share of biologically active compounds (BACs) with better sensory acceptability compared to commercial cultivars. However, their nutritional and biological potential is underestimated, as is their ability to be processed into functional food. The importance in preserving old apple cultivars can also be seen in their significance for improving the nutritional composition of other apple cultivars through innovative cultivation strategies, and therefore old local apple cultivars could be of great importance in future breeding programs.

This paper presents a computational tool for estimating energy generated by low-power photovoltaic systems based on the specific conditions of the study region since the characteristic energy equation can be obtained considering the main climatological factors affecting these systems in terms of the symmetry or skewness of the random distribution of the generated energy. Furthermore, this paper is aimed at determining any correlation that exists between meteorological variables with respect to the energy generated by 5-kW solar systems in the specific climatic conditions of the Republic of Cuba. The paper also presents the results of the influence of each climate factor on the distribution symmetry of the generated energy of the solar system. Studying symmetry in statistical models is important because they allow us to establish the degree of symmetry (or skewness), which is the probability distribution of a random variable, without having to make a graphical representation of it. Statistical skewness reports the degree to which observations are distributed evenly and proportionally above and below the center (highest) point of the distribution. In the case when the mentioned distribution is balanced, it is called symmetric.

This article represents the results of a study of changes in the properties of vulcanizates based on BNR-18 butadiene-nitrile rubber containing as stabilizers the experimental spatially hindered phenols Stafen, CO3, CO4, and industrial antioxidant 6PPD, after accelerated aging (100°C 96 h) and aging under full-scale exposure in extreme climatic conditions of the Republic of Sakha (Yakutia) during 2 years. In winter, the air temperature reached—48°C, in summer—+36.1°C. It is shown that the experimental sterically hindered phenols more effectively under natural exposure conditions. They are characterized by the most stability in terms of strength throughout the entire exposure period. Under conditions of accelerated aging, the vulcanizate containing the industrial antioxidant 6PPD is characterized by the greatest stability of physical and mechanical properties. According to the viscoelastic characteristics obtained in the dynamic loading mode, the contribution of the presented stabilizers in maintaining resistance to temperature and deformation effects compared with unstabilized rubber is confirmed.

Hygrothermal properties of building materials, climatic conditions and energy performance are interrelated and have to be considered simultaneously as part of an optimised building design. In this paper, a new approach to evaluate the energy consumption of residential buildings in Morocco is presented. This approach is based on the effect of coupled heat and moisture transfer in typical residential buildings and on their responses to the varied climatic conditions encountered in the country. This approach allows us to evaluate with better accuracy the response of building energy performance and the indoor comfort of building occupants. Annual energy consumption, cooling and heating energy requirements were estimated considering the six climatic zones of Morocco. Based on the results, terms related to coupled heat and moisture transfer can effectively correct the existing energy consumption calculations of the six zones of Morocco, which currently do not consider energy consumption due to coupled heat and moisture transfer.
