Potential Influence of Urban Sprawl and Changing Land Surface Temperature on Outdoor Thermal Comfort in Lagos State, Nigeria

Publié en ligne: 29 Jan 2021
Pages: 5 - 23

Résumé

Abstract

The continuous monitoring of the relationship between land surface temperature (LST) and land cover change is imperative for an inquiry into the potential impact of LST on human well-being, including urban outdoor thermal comfort in Lagos State, Nigeria. Using Landsat imagery, this study assessed land cover and LST changes from 1984 to 2019. Land cover was extracted, LST was determined from Landsat imageries and the land cover changes were linked to LST using the contribution index (CI). Afterwards, the universal thermal climate index (UTCI) was calculated to determine the heat stress levels. Findings confirm the presence of urban sprawl and new growth areas in previously rural Local Government Areas (LGAs) eastward, northward and westward of Lagos metropolis and in regions which lie on the fringe of the state's border with Ogun State. Also, a very strong link between high LST intensities and increasing concentration of urban areas in rapidly growing LGAs has been observed. This link further confirms the increased warming of the state, with an increase in mean LST of 2.16°C during 1984–2019. The UTCI which was used to gauge the influence of LST on outdoor thermal comfort ranged from moderate to strong heat stress levels. This study helps to strengthen the case for definite policies and actions which should be aimed at achieving moderate urban development through increased urban tree canopy/green infrastructure provision and carbon sequestration activities in urban design/landscape design, in Lagos State.

Investigating the Applicability of Unmanned Aerial Vehicles (UAV) Photogrammetry for the Estimation of the Volume of Stockpiles

Publié en ligne: 29 Jan 2021
Pages: 25 - 38

Résumé

Abstract

Accurately estimating the volume of earthworks is very important in mining engineering and construction. This estimation can be difficult because of the morphological condition of the stockpiles, hence, devising simpler, yet accurate methods of stockpile volume estimation is still a research problem in mining. Two non-invasive survey methods were compared in this research: the conventional ground-based and UAV-approach, for the survey of a twin-stockpile of gravel using Leica TS06 Total Station and DJI Mavic Air UAV, respectively. About 128 images of the area were acquired at 50 m flying height and 75% overlap during the flight mission. The images were processed using Agisoft Metashape Pro; a digital photogrammetric software, and the DEM obtained was used for the volume estimation. The total station data was also processed in ArcGIS to generate a TIN-model from which the volume was also estimated. The volume estimated from the TIN-model was compared with the volume estimated from the UAV-based DEM, using the volume obtained from the mill-machine as the standard. The obtained result shows that while 2750 m3 was obtained as the cumulative volume from the mill machine, the UAV approach yielded 2686.252 m3 and the ground survey approach gave 2830.713 m3. The percentage difference between the two methods compared to the actual volume is 2.94% and −2.31%, respectively. These results, and the result of the processing time analysis show that UAV approach is both accurate and time economical, which attests to the potentials of low-cost UAVs to provide robust alternative to the time-consuming and rigorous ground survey approach.

Modelling the Structure of Terrestrial Landscapes in Urban Areas

Publié en ligne: 29 Jan 2021
Pages: 39 - 49

Résumé

Abstract

The study of internal and external factors in the formation of an urban geosystem is determined by its complex structure and multiple connections. Based on geoinformation modelling, an analysis of the landscape structure of the city territory is carried out, which can be a basis for further geoecological research. Morphometric indicators, which make it possible to determine the elementary geochemical landscapes, are indicated according to the data of the digital elevation model. A standardised topographic position index (TPI) is used to determine locations. Spatial zoning according to the type of land use reflects the qualitative features of the external load and technogenic impact. The data on the composition of the lithogenic base show the properties of the depositing medium and determine the natural background. Number of categories of landscapes identified are 58, characterised by a homogeneous geological composition, technogenic load and conditions for the migration of matter. The ratios of various landscape zones have been calculated. The study area as a whole is characterised by the predominance of migration processes over accumulation.

Study of the Effect of Chemical Pollution with Coal-Fired Power Plant on the Fish of Lake Kenon (Trans-Baikal Territory, Russia)

Publié en ligne: 23 Mar 2021
Pages: 51 - 62

Résumé

Abstract

In this study, contamination of potentially toxic elements (Cr, Mn, Cu, Zn, Hg and Pb) and species dominant in the fish community of Lake Kenon – Carassius auratus gibelio (Bloch 1782) and Perca fluviatilis (Linnaeus 1758) – were investigated. Chemical elements in samples were determined by atomic emission spectrometry (iCAP-6500, Thermo Scientific, USA) and mass spectrometry (X-7, Thermo Elemental, USA). It was reported that water in Lake Kenon contained low concentrations of the studied metals. The bottom sediments are enriched with Mn, Zn, Hg and Pb. Bioaccumulation factors of chemical elements accumulated from the surrounding water for P. fluviatus and C. auratus gibelio in descending order are as follows: Zn > Pb > Hg > Cu. P. fluviatus accumulates Hg in equal measure from both water and bottom sediments. Manganese and mercury are accumulated in the muscles of C. auratus gibelio from bottom sediments. The high accumulation ratio of Zn and Hg in C. auratus gibelio was obtained from Chara sp. (24 times) and Chironomus spp. (38 times), respectively. High accumulation ratio of Zn (26 times) and Hg (29 times) in P. fluviatus was obtained from amphipods. At the same time, Hg in P. fluviatus muscles was accumulated at high level from Chironomus spp. (67 times). In this way, management decisions for mitigation practices in Lake Kenon should be focussed on for the disposal of wastewater from the ash dump contaminated with chemical elements.

Geotourism Potentials of Geosites in Durrës Municipality, Albania

Publié en ligne: 03 Mar 2021
Pages: 63 - 73

Résumé

Abstract

Present geological and geomorphological objects are non-living features that can enhance curiosity and increase the knowledge of Earth's history, through the development of geotourism. The municipality of Durrës, located in western Albania represents an active tectonic area with numerous landforms, an evidence of geodiversity and geoheritage. In this paper, the most typical geosites are identified mainly based on their scientific values as well as their geotourism potential. After the defining of 5 geosites, through geological and topographical map, we applied the Geosite assessment model (GAM). GAM is widely used in Europe on different areas and has given good results in the evaluation of geosites. The GAM method involves only experts’ opinions, which are essential for the preliminary development of geotourism in Albania. This method produce different main values (MV) and additional values (AV) score, which are very useful results in preservation, conservation and promotion of the area.

Zoning of Areas with Susceptibility to Oak Decline in Western Iran

Publié en ligne: 23 Mar 2021
Pages: 75 - 83

Résumé

Abstract

Zagros forests have the greatest impact on soil and water protection in western Iran. Despite this, a significant part of these forests, especially in Ilam province, have suffered a lot due to the phenomenon of oak decline. The first and most fundamental thing a person must know when combating this issue is the distribution of these areas in forests. Therefore, using the parameters affecting the decline in the forests of Ilam province and based on fuzzy logic, a map of susceptible to oak decline areas was prepared. In this study, the parameters of temperature and precipitation, slope, aspect, altitude, distance from farmlands, roads and forest density were selected as effective parameters and fuzzy gamma overlap method was used. The results showed that more than 77% of the oak forests in the province are highly and extremely susceptible to the decline. This confirms the need for rapid action to plan and protect these forests. In addition, the fuzzy method is proposed, which is considered as a fast and efficient method in preparing such maps for other areas.

Landscapes, Settlements and Traditional Housing in Samtskhe-Javakheti, Georgia

Publié en ligne: 20 Mar 2021
Pages: 85 - 95

Résumé

Abstract

A change in livelihood and folk architecture is an indicator of cultural landscape transformation, which is often the result of changes occurring in the natural and socio-political realms. The diversity of architectural types of buildings as an element of landscape diversity distinguishes our research region. The presented study deals with a long-term change of housing and architectural types of settlements. Our goal was to identify, geolocalise, and classify the vernacular architecture of Samtskhe-Javakheti within the different types of natural landscapes. For this purpose, we used the HGIS (Historical Geoinformation System) approach, which comprises the application of both historic sources and GIS technologies. We identified seven types of buildings in the study area, the characteristics of which depended on the natural landscape features. The following factors had been determining the geography of the construction: geology, seismicity, terrain, climate, access to building materials and defence. Dominant architectural types of buildings in the study region were as follows: fortress Rabat with stone houses, stone houses, semi-underground houses mixed with stone houses, semi-underground houses, terraced semi-underground houses, cave dwellings and wooden log houses. In modern times, it is quite rare to come across these kinds of architectural buildings, and there is a tendency of their disappearance.

The Debris Distribution Model for Removal Planning of an Urbanized Estuarine Complex

Publié en ligne: 23 Mar 2021
Pages: 97 - 107

Résumé

Abstract

We checked the spatial pattern of debris stranding at Praia de Santos (Brazil) in the first hour after the peak of high and low tide in summer and winter. We recorded and counted 20 types of debris (natural and anthropogenic) in 6 transects arranged in 3 zones along the beach (deposition, transport, and erosion). Canonical Correspondence Analysis (CCA) showed that buoyancy was an essential property in distinguishing debris stranding behaviours. The erosion zone, closer to the estuary showed that many mollusk shells, ropes and rocks, while plastics, styrofoam and fiber nylon were in the deposition zone. Throughout the estuary, we inspected the beach, identifying sections of origin and accumulation associated with the circulation system and currents. We propose the removal and recycling of debris from accumulation sites near highways and urban systems.

The engagement of young people is already considered essential for preservation and promotion of culture heritage. United Nations Educational, Scientific and Cultural Organisation (UNESCO), the European Commission, national governments and numerous organisations have undertaken a series of initiatives and projects that are aimed at engaging young people in the preservation and promotion of cultural values from the international level to the local ones. The aim of this study is to identify and analyse the role of youth in cultural heritage preservation and promotion in a local area, after considering the importance of their engagement. The research has been conducted on the basis of quantitative and qualitative data, which has been collected from primary and secondary sources. A survey is conducted in a local urban area (the city of Korça) that is rich in cultural heritage. This city is located in the south-eastern part of Albania. The data gathered through the questionnaire was later coded and analysed using SPSS v. 20 software. Based on the results of the research, the engagement of youth, especially students, in maintenance of archaeological sites, museums and libraries, training culture programs, guide walk tourist itineraries and participation in local heritage projects, enhance not only their awareness concerning heritage values, but also contributes towards their preservation and promotion. It is observed from the survey that the level of awareness of young people interviewed is higher among those who have been engaged in projects and cultural activities for preservation and promotion of heritage values. In terms of willingness expressed by young people, it is important to emphasise the role that education system, youth and heritage organisations and national and local government ought to play in encouraging the initiatives that involve more young people in heritage activities and projects.
