Зимостойкость хвойных растений в условиях северной лесостепи юга Тюменской области

We have studied 4 species of the genus fir, 3 species of the genus spruce (including (hereinafter) 14 varieties of Norway spruce and 12 varieties of blue spruce), 2 species of the genus larch (3 varieties of Western European larch), 7 species of the genus pine (7 varieties of mountain pine and 12 varieties of northern white cedar), 6 species of the genus juniper (3 varieties of common juniper, 5 varieties of savin juniper, a variety of Rocky Mountain juniper, 3 varieties of flaky juniper, 2 varieties of Virginian juniper and 3 varieties of Juniperus pfitzeriana) and a species of Siberian carpet cypress. All the studied plants were divided into three groups: highly promising, less promising and unpromising for this region. Most plants from the first group have large habitats indicating a wide range of their ecological potential. It has been found that the use of plants from the second group requires a careful selection of suitable locations and great attention to care measures. Plants from the third group are unpromising. It is impractical to use them actively in landscaping. The analysis also resulted in the development of a method for selecting coniferous plants for landscaping in the northern forest steppe of the south of the Tyumen region, based on their size parameters, species, varieties and needle colour. There are also 4 groups based on height: procumbent, scrubby, medium-grown, and tall-grown. Each group is divided into 3 subgroups based on the color of the needles: green, yellowish and caesious. The size of the plant has to be taken into account when creating ornamental plantations. Thus, fastgrowing varieties are useful for short-term decorative effects or in places where wind or noise protection is required fairly quickly. Medium-grown species are suitable for landscaping any territories and, with the use of restrictive pruning, even for small gardens or topiary art. Scrubby plants are suitable for landscaping small gardens, rockeries, small compositions. Depending on their growth rate, groundcover plants can be used as a lawn replacement, to stabilize slopes and create a carpet effect. For citation: Lyasheva L.V., Lyashev A.A., Steinberg Yu.S.

Combining methodologies on the impact of inter and intra-annual variation of wave energy on selection of suitable location and technology

In this study, based on 55 years’ worth of high-resolution simulated wave data using numerical modeling off the southern coasts of China, intra-annual and decadal variations of the wave climate and wave energy were evaluated. The results show that it is important to consider a sufficiently long time period for wave energy assessment to take into account the changing climate. The high-resolution wave dataset enabled the quantitative analysis in both nearshore and offshore, and the quantitative analysis was performed in two phases: First, using two different approaches. i.e., “Climate-dependent Sustainability Index” and “Wave Exploitability Index”, the wave power and its short and long-term changes were considered to prioritize the candidate stations for further assessment. Then, a modified “Multi-Criteria Approach” consisting of both sea state and Wave Energy Converters (WECs) was applied to determine the most suitable combination of WEC and location in the domain, which is Wave Dragon in the eastern parts of the domain with the energy production of around 92,000 MWh for a single device. The results provide the quantitative analysis for different scenarios of development plans in the study area on the selection of appropriate location and technology.

Selecting optimal site for solar photovoltaic plant in Ikwerre L.G.A., Rivers State, Nigeria

Erratic power supply is a serious problem to most part of Rivers State, Nigeria in general and Ikwerre Local Government Area in particular. This situation does not only halt social and economic development of the area but has also given birth to other social vices such as arm robbery, kidnapping, and other criminal activities. Renewable energy is an alternative form of energy aim at alleviating the problems of erratic power supply. It is generally considered as the cleanest form of energy. Solar photovoltaic is a type of renewable energy which derived its energy from the sun. The construction of solar plant requires the selection of suitable location for the generation of optimal energy. The purpose of the study is to determine suitable locations in Ikwerre Local Government Area, Rivers State to site solar photovoltaic plant using multi-criteria analysis (MCA) in ESRI’s ArcGIS. The dataset used for the determination of the optimal sites include; solar radiation and slope map produced from digital terrain model (DTM), pipeline, road network, land use/ cover map, soil map, and settlement. The datasets were converted to raster and reclassed into six classes for the purpose of data integration. The datasets were weighted according to their relative importance in the weighted overlay tool. Solar radiation has the highest percentage influence 40, followed by proximity to pipeline and road network which are 15 each. The model produced four suitability classes ranging from poorly suitable to highly suitable class. Highly suitable class has an area of 10139.87ha with 548 polygons, representing 15.78% of the study area. Further analysis was carried out using highly suitable class and settlement layer, it was found that three (3) optimal sites were obtained as most suitable for sitting solar plant. The three polygons were located in the region with very high solar radiation, accessible to road and away from built-up areas. The above results suggest the usefulness of GIS in site selection, particularly in sitting solar photovoltaic plant. It is recommended that further study should include transmission line which was completely omitted in this analysis due to inability to get the shapefile from the ministry of power.

Mapping the performance of photobioreactors for microalgae cultivation: geographic position and local climate

AbstractBACKGROUNDOver 90% of microalgae cultivations on a commercial scale are grown in outdoor systems, which means that the performance of these bioprocesses is dependent on the climatic conditions in each particular locality. Thus, the selection of suitable locations according to their climatic conditions is extremely important to develop technically and economically viable processes. This study aimed to assess the influence of geographic position and local climate on the microalgae culture performance in photobioreactors, as a strategy to map potential regions for commercial‐scale microalgae production. Six extreme positions of Brazil were chosen to represent their respective climates in the four seasons of the year.RESULTSThe climatic variables considered were temperature, light irradiance, and photoperiod. In terms of both biomass and lipid production in an annual overview, the results showed that tropical climates and low latitudes favor the microalgae culture. The highest annual average biomass productivity (0.278 g L−1 d−1) and annual average lipid productivity (0.056 g L−1 d−1) were recorded in Boa Vista‐RR (02° 49′ 12″ N), in summer.CONCLUSIONThe geographic position and the local climate are decisive criteria in the performance of these processes, being able to increase up to three and four times the biomass productivity and lipid productivity, respectively. © 2020 Society of Chemical Industry

The Application of Remote Sensing (RS) Technology in Renewable Energy Development: A Review

In recent times, the continuous dependence on fossil fuel as a major energy source has come under intense scrutiny in environmental and energy policy discourses. Such energy sources emit greenhouse gases (GHGs) – a major cause of climate change – and threaten global energy security and environmental health. Renewable energy (RE) sources such as solar, wind, hydro and biomass have gained increasing popularity as attractive alternatives around which global partnerships and cooperation continue to grow. The capital cost associated with the development of some of these energy sources are however huge, necessitating comprehensive evaluation of locational suitability before proceeding with RE investments. While several traditional methodological approaches for the assessment of RE potentials abound, the significant role of the remote sensing (RS) technology in this regard is enormous and hence represents the focus of this paper. Literature on the shift towards green energy, remote sensing technology, and its applications in the development of four renewable energy sources – solar, wind, hydro and biomass – are explored. Case studies were drawn from different geographies around the world to highlight the capabilities of the remote sensing technologies in RE development and variations in the approaches and methodologies adopted in RE resources assessments. The paper concludes that the role of RS technology in renewable energy is huge and growing. Notwithstanding, the need for multi-criteria analysis in the selection of suitable locations for RE investments makes the combination of both GIS and Remote sensing technologies necessary.

Cycling Traffic Development in Slovakia in the Terms of the City of Košice

Cycling traffic has been booming in urban agglomerations recently. This is due to the fact that using bicycles helps solve existing transport problems. The advantage is that it supports the limitation of the use of cars in city centers and thus reduces the negative impact of transport on the environment. It can be realized in various forms - using private bicycles or bike-sharing. Kosice includes among cities where introducing bike-sharing is considered. Kosice is a city that has its specific transport problems, whose partial solution may be to increase the support of cycling when one of the options is the introduction of a city bike-sharing system. The article offers a closer perspective at this issue in adaptation to real urban conditions. It introduces the possibility of introducing support for cycling traffic in the city of Kosice based on the selection of suitable locations for building the stations and the subsequent evaluation of selected localities based on the determined criteria using the proportional index method.

Managing Groundwater Nitrate Contamination from Livestock Farms: Implication for Nitrate Management Guidelines

Significant nitrate contamination of groundwater has been observed in various parts of the world; intensive livestock farming is one of the major causes. This paper reviews various guidelines/regulations, which have been developed in advanced countries such as USA, Canada, Australia, and Europe to combat this problem by designing effective monitoring and management programs. Monitoring programs deal mainly with selection of sites, number of monitoring wells, specific parameters, and sampling frequency, which are helpful for identifying the source and extend of the contamination. Management programs deal with selection of suitable location, site characterization, proximity of livestock facilities and drinking wells, and proper storage, maintenance of the facilities, and limits of manures application in order to minimize nitrate leaching into groundwater. The main aim of this paper is to help states/countries, which do not have any guideline, and consulting engineers/consultants/owners of livestock operation in the design of effective strategies for point source nitrate management.

The Combination of Expert Judgment and GIS-MAIRCA Analysis for the Selection of Sites for Ammunition Depots

This paper suggests spatial multi-criteria model in order to assist decision makers in the selection of sites which are suitable for ammunition depots (AD). They represent military facilities which have more criteria that need to be matched than civil structures. The proposed model is based on combined use of Geographic information systems (GIS) and multi-criteria techniques. The model application is presented in the case study of Carpathian region, the Eastern part of Serbia. The model deals with nine restrictions and six evaluation criteria. Decision Making Trial and Evaluation Laboratory—Analytic Network Process (DEMATEL-ANP) multi-criteria techniques are used to determine weight coefficients of evaluation criteria. Along with the above mentioned methods, this paper introduces a new technique for the multi-criteria decision making—MAIRCA (MultiAttributive Ideal-Real Comparative Analysis) method. The MAIRCA method is used for the ranking and selection of suitable locations. The results have shown that 45 km2 of the Carpathian region is very suitable for ammunition depot construction. The MAIRCA method chose location L1 as the most appropriate. Sensitivity analysis shows that the model is capable of identifying a suitable ammunition depot location. This approach can be helpful in determining suitable ammunition depot locations in other regions with similar geographic conditions and can also be successfully used for the suitability assessment of existing ammunition depots.

Genotype-by-environment interaction analysis of rice (Oryza spp.) yield in a floodplain ecosystem in West Africa

Abstract West Africa has large areas of river floodplains, most of which are not currently used for farmland. Rice ( Oryza spp.) is a promising crop for farming in floodplains because of its high adaptability to a wide range of water environments. On the other hand, there is great variation in soil fertility and water availability even in a small area within a floodplain. Hence, we evaluated 27 rice genotypes in four fields in three years in a floodplain of the Northern Region of Ghana to investigate genotype × environment (G × E) interactions for rice yield and to identify stable, high-yielding genotypes. The genotypes consisted of O. sativa , O. glaberrima and New Rice for Africa (NERICA), and many were selected for their reported submergence resistance because of the anticipated submergence damage in the floodplain. There were large variations in yield, which ranged from 0.14 to 5.35 t ha −1 depending on the location within a floodplain, genotype and year, and there were significant genotype, environment and G × E interaction effects on yield, accounting for 24.8%, 20.2%, and 28.2%, respectively, of the total variation. The results suggested that selection of suitable location with high soil fertility and low risk of submergence is necessary to achieve high yield in a floodplain. In addition, early sowing would be effective high-yielding crop management, which reduced the risk of submergence-induced damage just after sowing and secured sufficient growth duration to achieve high yield. Genotype IR42 showed the highest average yield among environments, but its yield stability was low. On the other hand, several genotypes including Amankwatia, a local aromatic cultivar adapted to irrigated and lowland environments, and IRBL9-W[RL], a blast-tolerant variety containing the Sub1 gene for submergence tolerance, showed high, stable yield. To put these results to practical use in other floodplain areas in West Africa, physiological mechanisms causing G × E interaction for rice yield should be further studied.

Environmental impact assessment for tidal energy schemes: an exemplar case study of the Strait of Messina

Tidal currents and ranges in the Mediterranean basin are generally low from a tidal energy perspective. The narrows through the Strait of Messina are an exception, exhibiting intensive tidal currents that have the potential for the economic exploitation. Maximum current velocities at spring peak tides through the Strait vary between 1.8m/s to more than 3m/s. Selection of suitable locations for tidal energy extraction for the exploitation of these natural tidal phenomenon is not, however, a simple process. Constraints must be satisfied, subject to basic criteria dependent upon local factors, technology limitation and economic consideration. In addition, the impact of large scale extraction on the underlying hydrodynamics, environment and ecology within the Strait has to be assessed and evaluated.This paper is a desk-based case study to show how a tidal resource may be environmentally assessed for energy extraction, using the Strait of Messina as an exemplar case
