The aim of the present study is to assess the contamination level of the soils around the central prison and the regional hospital of Ngaoundere (Cameroon) exploited for crop production. To achieve this objective, soil samples were collected from the surface at a depth of 0-20 cm and 20-30 cm and were analysed to determine heavy metals level on one hand and the enrichment factor (EF) and the geo-accumulation index (IGEO) on the other hand to better assess the level of contamination. Results showed that the concentrations of heavy metals in soils varied according to sites and ranged from 0.51±0.01 to 4.93±0.07 mg/kg for Cd, 10.57±0.01 to 99.47±0.80 mg/kg for Cu, 595.57±0.60 to 872.85±1.58 for Fe, 24.35±0.56 to 43.62±0.65 mg/kg for Ni, 35,25±0.26 to 307.21±0.32 mg/kg for Pb and 31.73±0.11 to 384.32±5.84 mg/kg for Zn. The sequence of heavy metal concentrations in the hospital and prison soils was as follows: Fe>Zn>Pb>Cu>Ni>Cd. Base on the IGEO and the EF the results showed, apart from iron, an accumulation of various metals in both prison and hospital soils. These soils are not suitable for crop production because there is a risk of contamination of the human food chain.","PeriodicalId":15886,"journal":{"name":"Journal of Geography, Environment and Earth Science International","volume":"16 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-08-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86680329","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The study investigates the population strategies to mitigate geomorphic hazards in Limbe within the past 20 years. Data collected through a sample of 200 questionnaires and interview, were analyzed using both qualitative and quantitative statistical techniques. The results reveal that geomorphic hazards have been recurrent in Limbe particularly in the months of June, July and August where the average number of days for rainfall is 27 days in a month. The frequency of hazards occurrence is very often and is highly significant at P=0.000. It also reveals that mitigation measures such as raising foundation, use solid structures and embankments, vary from one area to another within the selected sample sites. Thus, the management strategies to mitigate geomorphic hazards are still lagging behind as there is lack of sensitization/education, good rehabilitation schemes on the part of the authorities to make population avoiding flood and landslide prone zones. Therefore, there is need of management plan for geomorphic hazards in particular and disaster risk management in general that should integrate all stakeholders for a co-management between the Limbe city council and the communities in risk prone areas.","PeriodicalId":15886,"journal":{"name":"Journal of Geography, Environment and Earth Science International","volume":"4 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-08-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88411374","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Countries in Latin America are committed to increasing their school coverage, with projects that use renewable energy. In the municipality of Lerida, Tolima, Colombia; there is a need to expand school infrastructure in order to provide access to technology and reduce school dropout with the construction of solar classrooms. \u0000Aims: This research aims to evaluate the technical, economic and environmental feasibility for the construction of a classroom with photovoltaic energy system and technology equipment in the municipality of Lérida, Tolima, Colombia. \u0000Study Design: Case study, with quantitative, descriptive and prospective approach. \u0000Place and Duration of the Study: The case study was conducted in the municipality of Lérida, Department of Tolima, 73 kilometers from Ibagué in Colombia; between 2022 and 2023. \u0000Methodology: The methodology consisted in determining the size of a photovoltaic system based on the consumption of the selected equipment, the design and construction of the solar classroom with recyclable materials. Subsequently, the project was financially evaluated based on the social benefits that the project would provide. Finally, the environmental impact was evaluated to determine if the construction of the classroom is technically, financially and environmentally viable. \u0000Results: First, the costs and material for the civil works of the classroom were evaluated and it was determined that it was built with Lego-type plastic wood. Subsequently, the energy demand was determined with the technological equipment, identifying a demand of 2587 kW/hour, at 110V and with 8 hours of daily operation. With these data, the design of the photovoltaic system was carried out to cover the estimated demand, adjusted to the theoretical consumption of the equipment to be installed. With the energy demand, the selection of the number of panels was made, which resulted in 10 panels of 330 W with 5 effective hours of sun, a 3000 W inverter, a 4000 W regulator and 3 batteries of 100 Ah to maintain the energy autonomy of the classroom for 1 day. The photovoltaic system is projected with a useful life of 20 years, with the exception of the batteries, which is only 7 years. The next step was to carry out the cost-benefit analysis that determined the economic viability of the project, with a rate of return on investment of 3.6 years. Likewise, the benefits that the classroom would bring to the community and that are related to the objectives of developing quality education, with affordable energy and modern infrastructure were determined. The economic and social impacts were analyzed, which were positively high by making available technology available to the young people of Lérida that allows reducing the technological gap that generates inequalities and finally the environmental impact was evaluated, wh","PeriodicalId":15886,"journal":{"name":"Journal of Geography, Environment and Earth Science International","volume":"27 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-07-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82024181","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Lanteaume","doi":"10.9734/jgeesi/2023/v27i9703","DOIUrl":"https://doi.org/10.9734/jgeesi/2023/v27i9703","url":null,"abstract":"This paper offers a new contribution to our ongoing harmonization efforts concerning the chronostratigraphic model of the southern France Urgonian-type carbonate platforms, which surrounded the Vocontian Basin during the Early Cretaceous. A multi-stratigraphic approach on the classical sections of the Ardèche River gorges and the Saint-Remèze Plateau have been used for reconstructing the evolution of the Bas-Vivarais Urgonian domain along an inner-to-outer platform profile; the latter being nearly perpendicular to the eastern Vocontian platform margin. In our transect, the installation and first developments of the Urgonian platform domain occured during the early Barremian Taveraidiscus hugii and Kotetishvilia nicklesi ammonite zones. This first platform stage was interrupted at a brief emersion episode that lasted through the Nicklesia pulchella ammonite zone, and resulted in the deposition of a sedimentary wedge with limited gradual downward, basinward shift in inner platform facies. This was followed by the regional deposition of shallow-water communities dominated by corals, echinoids, and orbitolinids, which passes basinward into open-marine, ammonite-bearing marly deposits in the Saint-Remèze Plateau outcrops. This change in facies was previously referred to as the Serre de Tourre Beds (STB), and dated to the Kotetishvilia compressissima and Moutoniceras moutonianum ammonite zones. The STB are further identified to as the local sedimentary expression of the Mid-Barremian Event recording a brief warming climate pulse testified by the presence of Offneria simplex, a caprinid rudist of Caribbean origin. Above, there is a regional recovery of inner platform Urgonian facies during the early late Barremian showing a striking progradational basinward trend. The latter, and its subsequent developments are in need of investigations. Taken together, the general evolution of the Urgonian Bas-Vivarais domain shows strong similarities with the sedimentary context of the nearby Subalpine Urgonian platform during the early Barremian. The finding of common sedimentary signals is more difficult with the Provence platform domain at that time.","PeriodicalId":15886,"journal":{"name":"Journal of Geography, Environment and Earth Science International","volume":"34 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-07-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90741451","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Due to the significant spatial fluctuation of soil moisture, it is difficult to quantify it in a particular spot or field across a sizable region. Despite the thermal band's limitations in assessing soil moisture, MODIS and AVHRR, which are inappropriate were utilized in this investigation. The study examined the impact of soil moisture on dust outbreak. Soil moisture in the study domain was monitored using field techniques and the hybrid model. It combined multi-sourced remote sensing data, obtained from AMSER-E and FY-3 satellites.  AMSER-E satellite measures the light temperature in five frequencies ranging from 6. 9 to 89 GHz based on data obtained from AMSER-E. Findings revealed areas with a spatial scale of 25 km2 has a 12-hour time step or variability in dust storm, thereby influencing soil moisture content within the zone of study. In addition to introducing acceptable potentials of the passive microwave band for accurate and applied monitoring of the soil moisture, the present results are viewed as a reliable source for studies on drought in time scale. The study shows that Zabol in Sistan has the highest annual average of 80.7 dust storm days. Soil moisture estimates serve a great deal for preparing soil moisture maps and the evaluation of temporal and spatial variations of soil moisture in study region to address issues related to dust storms. \u0000In order to identify the areas affected by dust storms and understand how dust particles are dispersed in the Sistan region, satellite image processing was employed using MODIS 1 sensor images obtained from the TERRA satellite.","PeriodicalId":15886,"journal":{"name":"Journal of Geography, Environment and Earth Science International","volume":"8 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-07-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90191373","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
