Flood Incidence and Sustainable Development Planning Implications in Santchou, Cameroon

While studies on the incidence of flooding exist in several parts of Cameroon, very little empirical evidence has been reported for highly dynamic and urbanizing landscapes in Cameroon. Yet, micro level evidence on flooding and their development planning implications are required to advance theory building in the frame of development planning and hazard mitigation in rapidly urbanizing contexts. This paper bridges the knowledge gap by using the case of Santchou, a highly dynamic landscape, to: (a) analyse the spatio-temporal variations in flood incidence, (b) determine the drivers of flood occurrence, and (c) examine their sustainable development planning implications. To achieve these objectives, a representative sample of 141 households was conducted in five communities within the study area. This was complemented by key informant interviews (n=8) and field observations. Data was collected using the Kobo Collect tool. The collected data was analysed descriptively and presented as tables and bar charts, with the aid of the Statistical Package for Social Sciences (SPSS version 25). Cartographic data was analysed spatially and presented using maps. Based on the findings, the following conclusions were derived: Firstly, flood occurrence vary spatially in terms of severity, with very high intensity in the south east; this decreases towards the north west and western sections of the study area. Flood occurrence also vary over time with the peak of occurrence observed in the month of July and August which corresponds to the peak of the rainy season. Secondly, the most significant effects of floods include; the destruction of physical installations such as houses, household items. Floods equally affect human activities through the destruction of crops, livestock and the disruption of transport circulation. Furthermore, flood effects are less severe in Santchou Ville and Albatross neighborhoods compared to neighborhoods such as; Madagascar, Bessouck and Kassala Farm. Thirdly, while planning approaches exist at household, neighborhood and municipality levels, the most effective involves the use of sandbags and the cleaning of water channels. This study recommends that, sustainable development planning measures currently implemented at the household, neighborhood and municipal levels should be encouraged by the state and civil society organizations such as NGOs. Additionally, sustainable development planning measures should be implemented alongside proactive measures such as; flood alert signals, and the resettlement of inhabitants to safer areas. Future studies should assess the effectiveness of flood management approaches in the study area.

FORMA MILICIANA E SEUS PARADIGMAS NO ESPAÇO-TEMPO DO URBANO NA METRÓPOLE DO RIO DE JANEIRO

The article presents five hypotheses regarding our evaluation of the current emergence of the geographical space of the militia form. To construct this hypothesis, the Metropolitan West of Rio de Janeiro (MWRJ) has been selected as the preferred locus for the rise of this social form. In an exercise of regionalization, we connect the terms of this socio-spatial presence within the scope of the current center-periphery relationships transcribed in the Brazilian urban network. Presenting the hypotheses and weaving them from cartographic data, we bring elements to the understanding of the negative character of the modernization entangled in this fragment of the metropolis of Rio de Janeiro in recent decades. Keywords: Metropolitan West of Rio de Janeiro; Milita Form; Regionalization; Center-periphery Relation; Late Modernization

About the experience of medical-geographical atlas mapping of the North Kazakhstan region

The article is devoted to medical and geographical atlas mapping. The results and accumulated materials of medical and geographical research of the North Kazakhstan region are presented, systematized and collected in a single key in the form of a complex of maps and models - a thematic medical-geographical atlas. The development of the atlas was based on the generally accepted principles of integrated system mapping. An extensive array of literary, reference, statistical, and cartographic data was used to create the atlas. Geoinformation mapping was performed in the program ArcGIS 10.8. (ESRI Inc.). The stages of development, structure, and content of the atlas are described. The atlas includes maps reflecting the natural, socio-economic factors of the formation of the health of the population of the region, demographic characteristics. In addition, it presents a series of maps on the nosogeography of natural focal diseases, the organization of the health system, and natural healing resources. The developed atlas is of a reference and informational nature and is intended for specialists of the healthcare system of the North Kazakhstan region, geographers, ecologists, as well as persons interested in medical and geographical research and mapping.

PROBLEMS OF DETERMINING THE BOUNDARIES OF THE SUBURBAN AREA OF THE LARGEST CITIES OF UKRAINE

The article examines a relatively recent concept used in regulatory documents, known as the largest cities in Ukraine. Unfortunately, statistical data on the population size has not been kept in Ukraine for a long time, which makes it challenging to conduct the research in the most detailed and in-depth manner. Despite this, the study used data from enterprises and industries, cartographic data, and field surveys. It allowed us to identify seven potentially largest cities: Kyiv, Kharkiv, Odesa, Dnipro, Donetsk, Lviv, and Zaporizhzhia. The authors studied the concept of suburban areas in detail and found differences between different classes of suburban areas. We used works from various scientific fields: geographical, economic, sociological, legal, and urban planning, which makes this article interdisciplinary. Also, we considered the regulatory legal documents of the State Building Code, the Laws of Ukraine, and historical materials. The cities of this study tend to grow and spread geographically throughout the area, signalling us to revise previously accepted interpretations and norms of suburban areas. It led us to conduct the study and adopt a new definition of the suburban area of the largest city. Therefore, the ‘suburban area of the largest city’ is the territory located outside the largest city along transport and motorways and providing close partnership with the city in economic, environmental, recreational, cultural, labour, scientific, and other areas. The article considers the modern problems of the suburbs, such as territorial conflicts on the appropriation of land, conflicts on the use of territories not for their intended purpose, and clashes between developers of the residential sector, enterprises, and the ecological framework. In the latter, the natural flora and fauna system suffers the most. External factors also influence the slowdown of suburban development: military conflicts, instability of foreign policy, economic decline, and others. To prevent such a scenario, we have defined the goals and objectives of the suburbs. In the current situation in Ukraine, this study can help to facilitate further research on the development of territories. Keywords: suburban area, largest cities, planning, boundary, accessibility.

Digital Surveying for Revitalization of Finiq Municipality in Albania: Utilizing 3D Technologies for Heritage Preservation and Development

The Finiq Municipality in Albania is a rural region that is faced with a number of pressing challenges, including a declining population, isolation, and a lack of identity. These is- sues are prevalent in many rural areas of Albania and other countries and can have a substantial impact on the preservation of heritage structures and the overall development of the municipality. However, the territory possesses several potential advantages, such as its proximity to Saranda and the Albanian Riviera, the archaeological site of old Phoeniciae, and the 13th-century Orthodox monastery dedicated to St. Nicholas of Myra, as well as the qual- ity agribusiness production. Proper implementation of policies at the national, regional, and local levels could lead to a tourism-based revitalization of the area. In this framework, data plays a crucial role in project development as it forms the basis for informed decision-making and efficient planning. One of the key benefits of data is its ability to reveal patterns and trends, which can be leveraged for decision-making and improvement opportunities. In addition to demographic and sociological data, information describing the territory and human artifacts in their physical form is also essential. GIS tools are already in use and provide useful cartographic data, which effectively represents the complexity of the territory and the relationships between its various components. This data forms the founda- tion for creating advanced information systems, such as territorial digital twins, to deepen the knowledge of the territory. Integrated digital surveys, utilizing three-dimensional acquisi- tion technologies such as lase scanning and photogrammetry, can serve as a reliable source of input data for creating these knowledge tools. Point clouds offer valuable morphometric databases that are often critical for documenting not only architectural and cultural heritage but also infrastructure, modern artifacts, and larger portions of the territory. Different multis- calar approaches can be adopted to cater to the specific needs and requirements, for instance providing a detailed understanding of archaeological and monumental heritage, or the contextualization of settlements in the surrounding area. By integrating these data with GIS platforms and BIM models to create a comprehensive understanding of the municipality's territory, they can be utilized for preservation and conservation efforts, urban planning and development, and identifying potential structural issues. Additionally, the data collected through 3D survey technologies can be utilized to monitor the condition of the buildings and infrastructure, promoting better maintenance and planning, even considering the risks posed by the area, such as seismic risk. The digital data can also be used to create virtual tours and interactive models, promoting the municipality's cultural heritage and economic development. While the use of these procedures in a marginal area may initially seem disproportionate, it is not so much in relation to the subject of the survey, given the universally recognized historical and artistic value of some areas. The financial effort required to undertake such campaigns may seem substantial, but the project can be implemented in phases, integrated, and completed over time.

Monitoring of Channel Deformations of the Lower Dniester Using Topographic Maps and Satellite Imagery with the Implementation of GIS Technologies

Rivers are one of the most complex formations on the Earth’s surface; they are connected with the deep structure of the Earth, the landscape environment, and unpredictable weather cataclysms. The study aims to investigate the peculiarities of the geological structure and tectonics of the Lower Dniester region, examine the types of meanders, determine the horizontal displacements of the riverbed, and assess the impact of anthropogenic factors on the riverbed and riparian areas. The methodology is based on the use of tectonic maps, geological maps of Quaternary deposits, historical topographic maps, and satellite images to determine the long-term horizontal displacements of the riverbed, identify meander types, and study the meandering characteristics and their relationships with tectonic structures. Horizontal riverbed displacements were measured at 76 points using data from the 1980 map and a Sentinel-2 image obtained in 2020. For the purpose of studying the types of meanders and their analysis, it is proposed to use the characteristics of meanders and their relationships. This approach will allow for more efficient analysis and prediction of changes in channel processes under the influence of natural and anthropogenic factors across various temporal scales. The research shows that the Lower Dniester region is influenced by the tectonics of internal structures and the seismically active Vrancea zone in Romania. Additionally, a comparison of cartographic data from 1880 and 1980 and satellite images from 2020 allows us to assess how the territory of the Lower Dniester riparian area has changed under the influence of anthropogenic factors.

Analysis of Land Use Changes in the Sado Estuary (Portugal) from the 19th to the 21st Century, Based on Historical Maps, Fieldwork, and Remote Sensing

This study analyses land use changes in the Sado Estuary (West-Central Portugal) based on a multi-temporal analysis of 19th century cartographic data and 21st century remote sensing land use maps, updated by fieldwork. A GIS plot of land use evolution is summarized in a quantitative table. The comparison shows the changes in land use, with increasing occupation by human economic activities, including extensive agriculture and forestry, as well as localized urbanization and industrialization. The main elements of the landscape impacted by anthropogenic uses were (i) hydrography—river dams affected the flow dynamics and sedimentary processes in the estuary; (ii) vegetation—increasing agriculture and forestry reduced the area of native vegetation, which is now mostly occupied by vineyards, pine forests and cork oaks; (iii) wetlands—tidal and alluvial plains are being occupied by rice cultivation, aquaculture, industries, and ports; (iv) coastal dunes—new developments are occupying large areas of Holocene coastal dunes; and (v) natural environment—mining and dredging have affected some habitats and biodiversity. This analysis is intended to help the territorial organization of present and future economic activities, as well as to reduce environmental and social problems, thus promoting the long-term sustainability of this rapidly evolving region.

Mapswipe for SDGs 3 & 13: take urgent cartographic action to combat heat vulnerability of manufactured and mobile home communities

ABSTRACT Our research has established the extent to which extreme heat disproportionately impacts manufactured and mobile home communities (MMHC), posing challenges in achieving both targets of Sustainable Development Goal (SDG) 3 of ‘good health and wellbeing’ and SDG 13 of ‘urgent action to combat climate change impacts’. In Maricopa County, Arizona, USA, an alarming statistic of annually 30–40% indoor heat-related mortality occurs within a mere 5% of local housing stock dedicated to MMHC. Effectively addressing the multifaceted nexus of heat vulnerability and housing precarity necessitates the availability of geospatial microdata. Yet, given the idiosyncratic nature of ownership tenure within MMHC communities, sufficient microdata at the household unit level remain notably elusive through conventional tax records or other publicly available sources. In this paper, we assess how employing MapSwipe, a crowdsourcing application affiliated with the Missing Maps initiative, improves the completeness and precision of existing MMHC cartographic data inventory. Our approach harnesses MapSwipe’s micro-tasking methodology to identify absent MMHC locations within the state of Arizona. The contribution of this research is to present a viable methodology that organizes geospatial microdata around SDG initiatives and web-based volunteer mapping to effectively target the resources required to address the heat vulnerability of MMHC.

Методика оценки экономического ущерба подземным водам при эксплуатации гидротехнических сооружений

Introduction. The problem is that currently there are no standard indicators for the degree of groundwater contamination. As a rule, standard indicators for surface waters are taken as a criterion for assessing their pollution. However, as is known, the underground hydrosphere is a separate environment, and groundwater is a separate component of the environment. In addition, groundwater is a strategic reserve of clean fresh water for the population of the Russian Federation. Therefore, it is clear that the regulation of maximum permissible harmful effects on groundwater and maximum permissible discharges of harmful substances into groundwater bodies is currently extremely necessary. Due to the fact that there are no standard indicators, there is no economic regulation of the negative impact of economic activities on groundwater. And this impact is very significant. This has been proven by numerous long-term monitoring studies of the underground hydrosphere, which is under the influence, for example, of mining enterprises in the Urals Federal District. Materials and methods. This work uses hydrogeological (deposit groundwater regime and balance monitoring), geochemical, and geo-ecological (groundwater quality and pollution monitoring) research methods, as well as observation and statistical and cartographic data processing methods. The research is based on a large amount of accumulated data and signature fieldwork. Results and discussion. As is known, in 1998, Guidelines were developed for the development of standards for maximum permissible harmful effects on groundwater bodies and maximum permissible discharges of harmful substances into groundwater bodies. However, this technique did not find its application, either because of its imperfection, or because it was believed that groundwater is sufficiently protected from negative technogenic and anthropogenic influences, in comparison with other components of the environment and, therefore, is not regulated need. Now it is obvious that groundwater, just like other components (atmospheric air, soil, surface water) experience intense negative impact from human economic activity and they require their own standards and, of course, economic regulation of such impact. The authors of this article have significantly improved the methodology for developing standards for maximum permissible harmful effects (MPH) on groundwater bodies and maximum permissible discharges of harmful substances (MPD) into groundwater bodies. This method has been patented and on its basis, the article presents a new method for calculating economic damage to groundwater, developed and tested on the basis of our own research on two unique largest technogenic-mineral formations in the Middle and Southern Urals. Conclusion. The hydrodynamic method for calculating groundwater pollution and normatively permissible discharge underlies the methodology for assessing natural damage to groundwater from pollutants of technogenic-mineral formations. The methodology for assessing economic damage to the underground hydrosphere from sources of surface pollution is based on calculating fees for the discharge of pollutants within the limit and above the limit. Resume. Technogenic mineral formations intensively affect groundwater, which is an important resource in human life in the present and especially in the future. Therefore, their uncontrolled pollution is unacceptable, which predetermines the development of a methodology for assessing damage to groundwater. Suggestions for practical applications and directions for future research. The application of a methodology for assessing economic damage to groundwater during the operation of hydraulic structures initiates the development of effective measures for higher and more comprehensive extraction of minerals, treatment of industrial wastewater, and more careful design and construction of hydraulic structures.

Multicriteria solar photovoltaic potential evaluation for high educational buildings. Case study of Polytechnic University of Valencia, Spain

Solar PV technologies have been expanding rapidly, and the installed power has increased, especially in the last decade. Their inclusion in university buildings arises as a key factor for sustainable transition in cities, since they have an important potential as case studies for urban experimentation positive effects on students and other stakeholders. This paper proposes a method to determine the availability for installing solar PV in universities' rooftops, considering simulation and cartography data, together with a final experimental validation stage. Unavailable areas for each rooftop are determined, including obstacles, the inner use of the rooftop and shadowed areas. Finally, the method verifies the technical suitability for all the proposed scenarios and applies an economic-environmental multicriteria evaluation to select the most suitable one. The methodology is validated in the Universitat Politècnica de València Vera-Campus. In total, 88913 m2 of the rooftops are suitable for solar PV incorporation, representing 48 % of the total surface. 52 % of the solar PV installable capacity takes place in surfaces which can incorporate more than 100 kW, 20.6 % between 50 and 100 kW and 27.4 % less than 50 kW. Finally, the multicriteria evaluation proved that the scenario with all the possible installations is the most suitable one.

GEODESY IN SOLVING PROBLEMS OF SUSTAINABLE CITY DEVELOPMENT: ANALYSIS OF URBAN TERRITORY PLANNING

The article focuses on the creation and implementation of a geodetic planning system aimed at ensuring the sustainable development of urban areas. The main emphasis is on the use of open and accessible software, integration of full-fledged GIS and DBMS components. The process of determining the most suitable GIS platform for GSP included a detailed analysis of various GIS systems taking into account their functionality, which allowed to choose QGIS as the optimal solution due to its high functionality in the field of geodata management, support for various data formats, user interface and dynamic development. The structure of the GSP is based on two main platforms: the QGIS GIS system for cartographic data presentation and analysis, and the Microsoft Access DBMS for performing all data operations. Interaction between these platforms is provided through the eVis module built into QGIS, which allows for efficient planning of urban area surveys and land use management. The main tasks solved with the help of GSP are the planning of primary surveys to identify target plantations, detailed taxation of plantations with the creation of samples according to specified parameters, obtaining point maps of the distribution of various types of vegetation, planning sample surveys with specific geospatial conditions, as well as geo-information and tax analysis in in solving the problems of sustainable development of cities. The implementation of GSP provides significant advantages for planning the sustainable development of urban areas, allowing more efficient use of land resources, optimizing urban management processes and intensifying scientific research in this field. The development and integration of modern digital technologies in the field of urban planning play a key role in achieving the goals of sustainable development.

Development of a methodology for molecular genetic monitoring for the cholera causative agent

Background. The ongoing cholera pandemic determines the relevance of the development and improvement of methods for analysis of data on genome-wide sequencing of the cholera pathogen. This is of particular importance in the light of the challenges of import substitution of foreign products, including software.
 The aim of the study was to develop a methodology for molecular genetic monitoring for the cholera causative agent using online geographic information system (GIS) and analysis with its help of strains isolated in Russia earlier.
 Materials and methods. Data from genome-wide sequencing of 2598 toxigenic (ctxAB+tcpA+) strains of V. cholerae O1 El Tor, both obtained by the authors on the MiSeq (Illumina) platform, and retrieved from the NCBI database were used in the study. The SNP analysis software was developed in the Java and Python programming languages. Cytoscape program was used to visualize the dendrogram. The development of online GIS was carried out using the programming languages HTML, JavaScript and PHP. The freely distributed Leaflet library written in JavaScript was used as the core. Maps obtained from the OpenStreetMap community were used as cartographic data.
 Results and discussion. A universal set of SNPs and software have been developed to analyze the data of genome-wide sequencing of cholera vibrio strains. It was shown that the majority of strains were distributed among several large clusters. The most closely related strains for cholera vibrions isolated in Russia since 2001 have been identified. An online GIS "Molecular genetic monitoring for V. cholerae" has been created, which allows the recognition of closely related strains directly on an electronic map.

Between Gaulanitis and Hippos: The Roman Road in the Southern Golan Heights in Context

The Roman road that transverses the southern Golan is one of the best-preserved ancient roads in the region. The present study provides new evidence regarding its route, its date of construction and abandonment, and its military-administrative and geospatial relationship with the surrounding landscape and settlements. The research combines diverse methodologies, including historical cartographic data, survey, excavation, a mobility model of the region and visibility predictive analysis for watchtower positions. The results suggest that the road was constructed in the second half of the 2nd century CE. A system of watchtowers existed along it, and it apparently did not serve as a vital artery between the nearby villages and the road itself.

Квантовая география: задачи типизации, классификации и районирования

The possibility of using the mathematical apparatus of the quantum theory of computer science for modeling geographical phenomena in solving problems of typification, classification and zoning to explain the reasons for the integrity of territorial objects is discussed. The methods of trivial and principal bundles of differential geometry and functional analysis of virtual internal spaces of geosystems (geomers and geochores) are used. The advantage of the quantum description lies in the linear simplicity of equations and formulas reflecting both the typical functions of discrete quantum states of geosystems and the superposition of these states realized in the observed spatial patterns in nature and society. This approach is the result of the ascent from a simple understanding of geographical objects as systems of continuous connection of elements to the allocation of independent discrete layers of independent functioning (geomers), their polysystem equivalence in geochores and holysystem integrity in region. The integrity of objects is described by general equations that do not take into account the influence of the geographical environment, therefore they allow creating models of different geosystems in the same way. For quantitative analysis of cartographic data, methods of reliability theory are used, based on the identification of frequency distributions of geomer areas by height, calculation of reliability and safety indicators. The application of the ideas of quantum geoinformatics is demonstrated by the example of assessing the factorial influence on the habitus of landscapes based on the signs of territorial manifestation of facies of different factorial series (facies classes) of the localities of the Maly Khamar-Daban ridge and the altitude distribution of the geomes of the Transbaikalia.

SCENARIOS OF THE AREA DEVELOPMENT AS A TOOL FOR TOURISM DESIGN: AN APPROACH TO DEVELOPMENT

The development of tourist areas occurs under changing conditions; design solutions can quickly become outdated. The purpose of the study is to develop a method of adaptive scenario planning applicable for the design of tourist areas. The theoretical foundation of the study is a systematic and integrated approaches to the study of tourist areas, and the concepts of the recreation and tourism opportunity spectrum. The research materials include scientific works, cartographic data on sample areas, and the results of a stakeholder survey. We used observation, survey, and cartographic methods. The scenario development process includes 6 stages. The result is the creation of 3 types of interrelated scenarios: 1) spatial scenarios at the level of tourist opportunity zones, 2) spatial scenarios at the level of functional zones, 3) program scenarios. We studied examples of 4 types of tourist areas in the foothill and low-mountain regions of Altai; identified a range of basic tourist opportunities, including 11 types of spatial zones, as well as the features of a set of tourist opportunities for each sample territory. The proposed method for developing scenarios makes it possible to ensure the competitiveness for tourist areas in the future. This is due to having the widest possible provision of opportunities on the territory for different categories of visitors, as well as through monitoring and making changes to program and spatial scenarios at the level of functional zones.
