Integrating meteorological and geospatial data for forest fire risk assessment

Understanding the factors that cause fire is crucial for minimizing the fire risk. In this research, a comprehensive approach was adopted to recognize factors influencing forest fires. Golestan National Park (GNP) was considered as a representative area with a humid climate in this study. Initially, using the Multi-Criteria Evaluation Method, a fire risk map was created by analyzing natural and human factors, and vulnerable areas were identified. Then, the relationship between key elements such as meteorological conditions, Land Surface Temperature (LST), and precipitation, with the occurrence of fire in different years was investigated. CHIRPS and Landsat data were utilized to assess LST changes and precipitation. 23-year changes in fire occurrence areas in GNP were acquired using MODIS products. The results of the data analysis showed that the highest number of fires occurred in forest areas, and in the fire risk prediction map, the extremely high-risk class is completely consistent with the ground truth data. The assigned weights, derived from expert opinions, highlight the substantial significance of elevation, and distance from roads and settlements. Additionally, the effectiveness of the model in providing reliable forecasts for fire risks in GNP is highlighted by the ROC curve with an AUC value of 0.83. Forest fires within GNP exhibit a distinct seasonality, predominantly occurring from July to December. During the warmer months, by coinciding with summer excursions, human activities may contribute to the ignition of fires. In 2013 and 2014, rising fire incidents correlated with elevated temperatures, hinting at a potential connection. GNP fires showed an upward trend with higher monthly LST and a downward trend with increased annual precipitation. The results showed that there is a relationship between LST, precipitation, and the occurrence of fire in GNP. Approximately 176.15 ha of GNP's forest areas have been destroyed by fires over the last two decades. This research demonstrated that there is a dynamic interaction between environmental conditions and fire incidents. By considering these factors, managers and environmental planners can develop effective strategies for managing and preventing forest fire risks.

Towards a better psychological satisfaction: developing a mixed multi-criteria evaluation system to urban ‘Not in my back yard’ facilities siting

‘Not in My Back Yard (NIMBY)’ facilities are psychologically sensitive to urban and regional development. Multi-criteria evaluation (MCE) method has been widely used for the decision-making of optimum siting of urban NIMBY facilities which aim to improve residents’ psychological satisfaction. However, the evaluation of qualitative criteria in siting analysis remains under researched, such as the insufficient focus on urban and regional spatial development, social public opinion, and psychological factors. Thus, the effective improvement of MCE method through an interdisciplinary view can optimise the decision process and advance the factor assessment system of siting, which helps to supplement qualitative criteria evaluation. The specific improvement steps are as follows. The first step is to introduce the mixed MCE method to improve the qualitative criteria evaluation method by pre-processing qualitative criteria with min–max standardisation and normalization. This process transfers all negative factors to positive ones and transforms the F function to linear functions. The second step is to optimise the existing two-phase siting decision-making including the feasibility evaluation phase and the MCE phase. The third step is to propose a modular criteria system composed of urban and regional spatial planning, social psychological factors and the corresponding improvement strategy of this system from three perspectives of composition, measure, and weight. We argue that the improved method could be broadly applied to optimum siting decision of urban NIMBY facilities and enhance the psychological satisfaction of residents.

Evaluating Attractiveness of Newly Introduced Flights – Results of a Study for the Ostrava International Airport

Abstract The paper addresses the issue of evaluating the attractiveness of new airport connections, one of which is a global transfer hub and the other is a regional European international airport. The attractiveness of new connections expressed, for example, by predicting the demand for new flight routes has long been studied, mainly using gravity models. The aim of the presented paper is to check whether an approach based on gravity models could be replaced with other approaches, in this case by multi-criteria evaluation methods. Questions of substitution of approaches based on gravity models, compiled for demand prediction, are relevant in cases where there are not enough input data for existing gravity models. The absence of input data occurs especially in cases where either there is no historical data on the operation of flights, or historical data do not have current significance, e.g. the operation of the flight has been interrupted for a longer time. The results of a study carried out for Ostrava International Airport located in the Czech Republic, show that gravity models for which relevant data are not available can be fully replaced by multi-criteria evaluation methods.

Comparison of Land Suitability Methods for Estimating Quantity of Maize Yield in Calcareous Soils

ABSTRACT The modeling and assessment of land suitability is a prerequisite for land development and is one of the necessary needs to prevent land degradation. Maize is considered to be the most important crop, covering significant areas of agricultural lands in widely different regions across the world. However, not all available lands are equally suitable for maize cultivation. The main objective of this study was focused on identifying the potentials as well as the limitations of studied calcareous soils for maize cultivation in north Khuzestan province, Iran. Furthermore, some parametric models and multi-criteria land suitability evaluation methods for physical, chemical, fertility, and climatic factors (MC-LSE) were compared in estimating the maize yield. The required samples were taken from 23 land units by excavating control pedons. The necessary physicochemical parameters were then measured in the laboratory. The land indices were calculated by using different methods. The maize potential production of the investigated area was then obtained based on the climatic conditions. Finally, using land indices and the potential production, the estimated yield for each land unit was calculated and compared with the actual yield data. The obtained results indicated that the main limiting factors for maize yield in the region are high soil CaCO3 content, high salinity, high alkalinity and low organic matter. A comparison of predicted and actual yield indicated that the corrected square root method is accurate enough to assess land suitability and to estimate the maize yield with a high coefficient of determination (0.91) and a low RMSE value.

A methodological approach to optimizing financial resources to increase the level of economic security in a dynamic external environment

Abstract The purpose of the article is to present a new approach to the optimal selection of financial resources to increase the level of economic security in a dynamic external environment. The scientific question arises as to which of the possible options is optimal, taking into account the dynamism of the external environment and security needs. The object of the study is the economic safety of industrial companies. The methodology is based on modern methods of system analysis, multi-criteria evaluation and paired comparison. The main result of the study is the proposed approach to assessing resource support for the implementation of a security mechanism, which, based on the actual limitations of human, organizational and financial resources at the disposal of most Ukrainian enterprises, can significantly improve the efficiency of their use without reducing the effectiveness of actions which are aimed at increasing competitiveness. The study has limitations, since it only takes into account the specifics of enterprises in the industrial sector of this economy, and therefore the options for financial resources are adjusted accordingly.

Mapping of Multiple Hazards in the Cilongkrang Sub-Watershed, Majalengka, Indonesia

The intensive agricultural activities in the Cilongkrang Sub-Watershed are causing environmental changes that can lead to various disasters. This study aims to map the spatial distribution of multiple hazards, including flash floods, erosion, and landslides. Three hazards selected because the critical condition of Cilongkrang Sub-Watershed as an upstream area caused the area to be prone to those hazards. The flash flood hazard model was created using the Flash Flood Potential Index (FFPI) method, which uses land use, slope, vegetation cover, and soil texture. The erosion hazard model was created using the Universal Soil Loss Equation (USLE) method with parameters such as erosivity, erodibility, slope length factor, crop management index, and soil conservation index. The landslide hazard model was created using the Spatial Multi-Criteria Evaluation (SMCE) method, which uses slope, landform, land use, and soil texture. The results showed that the dominant flash flood-prone areas were in the medium class of 1.556 hectares, the erosion tended to be very low, which was 2.699,5 tons/ha/year, and The Argapura Sub-District encompasses multiple regions that are highly susceptible to landslides.

STRATEGIC AND LEADING DOMINANTS OF OVERCOMING ECONOMIC - MANAGEMENT DEVIATIONS OF CONSTRUCTION PROJECTS USING FUZZY LOGIC

The article defines the directions of functioning of the construction industry and stakeholders of construction enterprises, reveals the main directions and peculiarities of the functioning of construction enterprises in the conditions of martial law (during the full-scale invasion of the Russian Federation on the territory of Ukraine) and substantiated directions of transformational development in the period of post-war reconstruction. The components of the theoretical-methodological platform for the formation and implementation of development management of construction enterprises have been developed using a methodical approach to the evaluation of strategic sets of the enterprise based on the improvement of the classical quantitative strategic planning matrix (QSPM, Quantitative Strategic Planning Matrix). As a conceptual basis for identifying such factors, the McKinsey “7S” model was used, according to which all factors are grouped according to the signs of belonging to the following components: strategy, skills, common values (corporate culture), structure, employees, systems and style. As a result of the study, the factors affecting the formation and implementation of the adaptive capacity of the construction enterprise to the transformational changes of the operating system are proposed: labor productivity in the studied period; the ratio of administrative expenses to wages in operating expenses; the share of employees with higher education in the total number of management personnel; experience of management personnel; the ratio of labor costs to wage costs. The processes of economic-mathematical modeling of the influence of system factors on the integral indicator of the level of transformational ability of the enterprise are determined. To achieve the goals, the work uses methods of strategic diagnostics and fuzzy methods of multi-criteria evaluation with the help of the Matlab Fuzzy Logic Toolbox application program package.

Potentials and opportunities of solar PV and wind energy sources in Saudi Arabia: Land suitability, techno-socio-economic feasibility, and future variability

Solar and wind energy sources hold significant potential to meet the escalating energy demand in Saudi Arabia sustainably. This research aims to assess the feasibility and prospects of deploying solar photovoltaic (PV) and wind energy systems in Saudi Arabia (SA). The study adopts a comprehensive approach, encompassing spatial analysis of land suitability, techno-socio-economic feasibility studies, and prediction of renewable energy (RE) resource variability and trends using machine learning techniques. Geographical Information System (GIS) spatial analysis is employed to identify suitable areas for establishing solar PV and wind farms based on multi-criteria evaluation methods. Techno-socio-economic feasibility analysis of solar PV and wind energy systems, under various configurations and scenarios, is conducted using the System Advisor Model (SAM) tool. Furthermore, a Support Vector Machine (SVM) machine learning algorithm is developed and deployed to forecast Global Horizontal Irradiation (GHI), wind speed, and influential weather parameters at different locations in SA. The projections of these variables derived from global climate models are utilized to analyze prospects and variabilities. The land suitability analysis identified four optimal locations for large-scale solar PV fields in Tabuk, Al Madinah, Makkah, and Riyadh provinces. Additionally, four promising wind farms were found in Al Madinah, Makkah, Riyadh, and Eastern provinces. The analysis also identified one location in Al Jouf province suitable for hybrid systems combining solar PV and wind energy. The techno-economic assessment revealed that wind farms performed best overall, achieving a capacity factor of 42.6 % in Al Madinah province. Although current tariffs render projects economically unviable, solar PV, wind energy, and hybrid solar PV-wind technologies are economically feasible in SA at Power Purchase Agreement (PPA) rates above $32.8/MWh, $26.1/MWh, and $50.6/MWh, respectively. The social development analysis estimated potential job creation from solar PV and wind energy deployment under different scenarios from 2020 to 2060, indicating that more ambitious climate targets could translate to millions of renewable energy jobs. The SVM model predicted solar irradiance with an R-squared value of 0.893. The CMIP6 model was then used to project the GHI for SA in 2049, suggesting an increase of approximately 19 %. Wind speed is also expected to rise roughly 5 % over the same period. The integration of GIS spatial analysis, techno-socio-economic modeling, and machine learning-based forecasting provides comprehensive insights into harnessing solar and wind energy in SA. This study facilitates evidence-based planning and risk assessment, crucial for a sustainable energy transition. The insights and roadmap derived from this research can inform policy frameworks, support the United Nations Sustainable Development Goals (UNSDGs), and attract private investments for RE development in SA. Consequently, this study establishes solar and wind energy as viable and promising solutions for meeting SA's growing energy demands sustainably, while minimizing the associated environmental impact.

Spatial Planning of Marine Protected Areas (MPAs) in the Southern Caspian Sea: Comparison of Multi-Criteria Evaluation (MCE) and Simulated Annealing Algorithm

Protected areas are referred to around the world as the basis of conservation strategies. Designation of marine protected areas (MPAs) is to preserve marine biodiversity and protect species, habitats in the seas, and oceans. The simulated annealing algorithm (SAA) with other algorithms (swap iterative improvement, normal followed by two step, two step iterative improvement, and normal iterative improvement) in MARXAN conservation solutions software and the multi-criteria evaluation (MCE) method were used to locate MPAs in the Southern Caspian Sea. Then, four methods were examined for site selection that include: (1) Simulated annealing algorithm, (2) MCE with zonal land suitability (ZLS), (3) MCE with compactness and contiguity, and (4) combined method of multi-criteria evaluation with spatial constraints and a simulated annealing algorithm (improved MCE). In the MCE method, we applied different weighted scenarios to locate MPAs. The criteria for determining the desired regions of MPAs included 12 factors gathered in three groups, including: (1) Ecological criteria (distribution of fish Huso huso, Acipenser persicus, Acipenser stellatus, Rutilus frisii kutum, and Alosa braschnikowi; location of coastal protected areas, distance from coastal rivers (Coastline), distance from estuaries and deltas); (2) Physical criteria (distance from the coast, shore sensitive areas); and (3) Socio-economic criteria (distance from densely populated coastal cities, distance from industries near the coast). The results of comparing the algorithms in MARXAN 4.0.6 software showed that the simulated annealing algorithm has a better ratio of border-length/area than other algorithms. Also, the combined method of MCE (improved MCE) selects the best protection patches in terms of location, taking into account the seascape ecology metrics (e.g., patch compactness, edge density, normalized entropy, area metric for patches). Moreover, the results of the comparison of four methods for proposing MPAs based on seascape metrics showed that the combined method of MCE considers a protection network with more contiguity and compactness than the simulated annealing algorithm. The use of seascape ecology can help to preserve and create larger and denser patches in the arrangement of protective areas, because such a selection of protective areas is nature-inspired and can be more bold and appropriate in the course of conservation planning.

Participatory evaluation of cultural heritage adaptive reuse interventions in the circular economy perspective: A case study of historic buildings in Salerno (Italy)

Adaptive reuse of cultural heritage can be a valid strategy to recover heritage buildings in a state of abandonment or underuse, as well as to implement the circular economy model in cities and regions, contributing to the achievement of climate objectives, to social cohesion, wellbeing and quality of life, making cities more attractive, safe, sustainable and resilient. The aim of this paper is to develop and test an ex-ante evaluation methodology to support participatory decision-making processes for the adaptive reuse of cultural heritage according to the circular economy perspective. A multidimensional and multicriteria evaluation framework was experimented in the city of Salerno, Italy, to assess alternative solutions for the adaptive reuse of four large historic buildings in abandonment, and identify a satisfying solution based on interactions with local stakeholders. The TOPSIS (Technique for Order Preference by Similarity to Ideal Solution) multi-criteria evaluation method was used to compare adaptive reuse project alternatives including stakeholder objectives and preferences. Starting from 14 adaptive reuse proposals, the participative evaluation methodology supported stakeholders in the identification of 4 preferable solutions further developed and co-designed, as well as in the search of a final satisfying solution engaging diverse stakeholders groups. Moreover, operational circularity criteria for the adaptive reuse of cultural heritage were identified. The results of the study show the potential of Multi-Criteria Decision Analysis (MCDA) mixed with participative methods for co-design and co-evaluation to support inclusive decision-making processes for circular adaptive reuse of cultural heritage.

Modelling malaria vulnerability hotspot by using geospatial techniques: the case of Kindo Koysha Woreda, Wolaita Zone, Ethiopia

Malaria is a serious, acute disease spread by female Anopheles mosquito bites. Malaria is an epidemic in the Wolaita Zone, affecting 85% of the population despite the implementation of effective prevention and control measures in the area’s public health services. The main objective of this study is to apply geospatial techniques to environmental, socioeconomic, and epidemiological parameters that increase certain conditions for malaria incidence to identify malaria vulnerability hotspots using a multi-criteria evaluation method. The malaria vulnerability hotspot map is identified by using AHP and the malaria hotspot identification algorithm. The findings show that the research area is 51% very high and highly vulnerable (224.14 km2), 26% moderate (116.560 km2) and 23% low vulnerable (103.600 km2). The western part of the area, which is near the Omo River and has low elevation, is highly vulnerable to malaria incidence. Reliable malaria vulnerability hotspot maps are critical for estimating the scope of the problem and, consequently, the resources required to combat malaria.

ОЦЕНКА ЭКОЛОГИЧЕСКОЙ БЕЗОПАСНОСТИ И ЭНЕРГЕТИЧЕСКОЙ ЭФФЕКТИВНОСТИ ТРАНСПОРТНЫХ СРЕДСТВ, ОБСЛУЖИВАЮЩИХ МАРШРУТЫ ГОРОДСКОГО НАЗЕМНОГО ТРАНСПОРТНОГО КОМПЛЕКСА

The urban passenger transport complex is the most important part of the infrastructure of modern cities and provides a number of key functions. The condition for the effective operation of the transport complex is the balanced development of the subsystems included in its structure, which in turn necessitates the formation of a methodological framework that determines the conditions for such development. Based on the indicated provisions, the purpose of the study is formulated, which is to increase the efficiency of the operation of vehicles serving the routes of the urban ground passenger transport complex, based on the results of an assessment of their environmental safety and energy efficiency. To achieve this goal, it is necessary to solve a number of tasks: – study and analysis of the content of research papers, regulatory and technical documents in the field of environmental safety assessment of energy efficiency of vehicles; – development of a methodology for assessing and comparative analysis of environmental safety and energy efficiency, vehicles serving urban public transport routes; – assessment of environmental safety of various categories of vehicles serving the routes of the urban ground passenger transport complex; – generalization and analysis of the results obtained, formulation of conclusions and practical recommendations. During the study, an approach was used that assumes: modeling of energy consumption parameters of vehicles implementing various technologies of fuel and energy supply and a comparative assessment of indicators determining their energy efficiency and environmental safety in traffic conditions on urban passenger routes. Based on the implemented approach, the methods of system and statistical analysis of the initial information, mathematical modeling and methods of multi-criteria evaluation of the results are used in the work. The main result of the study is the numerical values of the indicators of energy efficiency and environmental safety of vehicles implementing various technologies of fuel and energy supply in the conditions of urban ground passenger transport complex, which is the scientific novelty of the study. The use of the obtained values in assessing the efficiency of passenger transportation by vehicles of various categories allows for the formation of a fleet of vehicles based on the results of a multi-criteria analysis. One of the directions of further research involving the use of the results obtained is the development of a comprehensive methodology for determining the optimal structure and coordinated formation of subsystems that make up the urban ground passenger transport complex.

МЕТОД МНОГОКРИТЕРИАЛЬНОЙ ОЦЕНКИ ЭФФЕКТИВНОСТИ ТЕХНИЧЕСКИХ СРЕДСТВ В ОРГАНИЗАЦИОННО-ТЕХНИЧЕСКИХ СИСТЕМАХ

Evaluation of the efficiency of technical means is an important practical task at the stage of selecting their composition when designing complex organizational and technical systems. The author's method of multicriteria evaluation of technical means efficiency on the basis of dimension analysis is proposed, which allows to take into account many of their private characteristics. This method allows solving the problems of determining the quantitative values of generalised indicators of efficiency and effectiveness of technical means and, on their basis, selecting the preferred option for inclusion in the structure of organisational and technical systems. A practical example of using the method to select sensors in the synthesis of fire protection system of the object is presented.

Assessment of the Lithuanian Pig Farming Sector via Prospective Farm Size

Scientists, politicians, and practitioners are debating the current structure of pig farms in Lithuania, as medium and small farms have almost disappeared over the past decade. The debated problem is whether the revitalization of medium and small pig farms would sustainably contribute to self-sufficiency in pork production. Therefore, this research aims to determine which farms in terms of size could offer the best prospect for Lithuania. In order to achieve this aim, the multicriteria evaluation method TOPSIS (Technique for Order Preference by Similarity to an Ideal Solution) was used. The production and economic indicators of the Lithuanian pig farming sector in Lithuania and in the context of the selected EU countries of Belgium, Denmark, Germany, Estonia, Spain, France, Latvia, Netherlands, Austria, and Poland were analyzed. The main research period was 2004–2022. The multicriteria evaluation led to the conclusion that Danish pig farms were the best-managed. Large industrial farms were found to dominate in that country. Large pig farms (approximately two thousand sows) appeared as the best prospect in Lithuania: they took first place in the years examined (2016–2021). The criterion estimate of their assessed indicators was much higher than that of the medium (100 sows) and small (20 sows) farms. The main reasons are significantly higher labor productivity, lower cost, lower price, and better production indicators. Large pig farms generate relatively higher incomes and can meet the increasing environmental requirements and devote a larger part of the income to wages. Further research should consider the European Green Deal and the Farm to Fork Strategy, which are of great importance to farms and policymakers.

INTEGRATION OF MIGRANTS INTO THE COUNTRY’S SOCIAL ENVIRONMENT: THE CASE OF LITHUANIA

Migration is one of today’s most sensitive and relevant topics. In 2022 alone, 32.5 million people worldwide will have left their country due to war, political instability, economic hardship, climate change, and other reasons. In recent years, the constantly growing flow of migrants to developed countries poses increasing challenges to the institutions and organizations of those countries, which are looking for new ways of integrating migrants into the social environment. It is difficult for state institutions that do not have the right tools to assess the integrity of the state, and it is difficult to control the ongoing migration processes and quickly make decisions regarding the increased flows of migrants, which could be solved promptly with minimal use of resources. One of the most important solutions for overcoming the challenges of migration is using a dynamic complex instrument that would allow us here and now to identify the causes of changes and efficiently mobilize the necessary resources to solve the challenges of migration that are usually not planned. The article aims to form a complex evaluation instrument to integrate migrants into the social environment. To achieve the goal, a systematic, comparative analysis of concepts and methods published in the scientific literature, statistical processing, and multi-criteria evaluation methods (COPRAS), and the method of determining weight coefficients (CRITIC) is applied.

Assessment of the economic security of Baltic port cities’ competitiveness

City competitiveness is a complex product of local and international conditions, local characteristics, social and economic superstructure, and the actions of individual companies. Although many scientific studies have examined the country’s and urban competitiveness, the competitiveness of port cities still needs to be assessed comprehensively, taking into account their crucial economic role. The purpose of this paper is to evaluate the competitiveness and economic security of the Baltic port cities (Klaipėda, Riga, and Tallinn). Statistical processing and multi-criteria evaluation methods (SAW, COPRAS, and TOPSIS) were chosen to achieve this goal. The comparative analysis showed that the population change in port cities is not significant for the final result of the competitiveness assessment, and the unemployment rate in port cities is lower than in the country. The assessment of the competitiveness of port cities from the point of view of economic security shows (after checking such indicators as unemployment rate, company income, and infrastructure) that Tallinn is the most competitive port city according to the three multi-criteria evaluation methods, while Klaipėda is the least competitive. The assessment was carried out in three stages to monitor changes in the situation of port cities, compared to changes in a certain indicator and the costs of timely solutions or the improvement of the city’s position in relation to other cities.

GIS-Based Multi-Criteria Evaluation (MCE) Methods for Aquaculture Site Selection: A Systematic Review and Meta-Analysis

With the growing demand for aquatic products, aquaculture has become a prominent means of meeting this demand. However, the selection of suitable sites for aquaculture remains a key factor in the success of any aquaculture operation. While various methods exist for site selection, geographic information system (GIS)-based multi-criteria evaluation (MCE) methods have emerged as the most widely utilized approach to identifying potential aquaculture sites. Following the guidelines of the preferred reporting items for systematic reviews and meta-analyses (PRISMA), this paper presents a systematic review and meta-analysis of GIS-based MCE methods used in aquaculture sites selection. The objective of this study is to offer a comprehensive overview of existing research in this field and develop a general model for selecting sites for fish and shellfish aquaculture. The main findings indicate a growing number of studies utilizing GIS-based MCE in aquaculture site selection in recent years, with Asia being the leading continent in terms of publications in this domain. Among the journals publishing in this field, the Aquaculture journal stands out as the top publisher. Using consistent criteria across the reviewed studies, two models have been generated, each consisting of four sub-models: water quality, soil quality, infrastructure, and socioeconomic factors; and topography, environment, and physical parameters. These models can aid future researchers and assist decision-makers in identifying optimal locations for aquaculture development.
