Experimental and survey research designs were implored in the study utilizing GIS and spatial analysis approaches. Both primary and secondary sources of data were used. The primary data were generated through laboratory analysis of soil samples from 15 randomly selected sites within the metropolis;and 800 valid copies of socio-economic questionnaire administered to 800 respondents. Also, public hospitals were visited to ascertain the commonest soil borne diseases in the area. Four research questions, four specific objectives and two hypotheses guided the study. The hypotheses were tested with one sample t-test and one sample chi square using SPSS. Standard scientific and laboratory procedures were followed in the collection and analysis of soil samples. Findings of the study include: urbanization-related activities (e.g. waste dumpsites, mechanic workshops, abattoirs, etc.) cause significant changes on soil quality in the area; and this result to the emergence of soil borne diseases (e.g. Vascular witts, Ascaris lumbricoids,Trichuris trichiura, Strongloids stereoralis) which affects residents’wellbeing. However, there is significant difference in the perceived socioeconomic effects of the diseases across the area. Specifically, laboratory results for soil analysis show that (mean values): pH 7.22, temperature 25.62 °C, PO4 0.342 mg/kg, Pb 120.62 mg/kg, K 66.81 mg/kg, NO3 mg/kg. The study recommended for enforcement of physical planning and development control laws; regular evaluation of the quality of the soil, and restriction on the location of mechanic workshops and waste dumpsites around the metropolis.","PeriodicalId":165093,"journal":{"name":"Journal of Geographical Research","volume":"212 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-01-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128643578","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}

To clarify and compare differences between counties, county-level cities and municipal districts is the primary premise for the study of administrative division and urban development. This paper analyzes the institutional differences between counties and county-level cities, as well as counties, county-level cities and municipal districts, from the aspects of organizational structure, urban construction planning, land management, finance, taxation and public services. The research shows that the establishment of counties, county-level cities and municipal districts adapt to different levels and stages of economic and social development,and the conversion from county to county-level city and the conversion from county (or county-level city) to municipal district are both important transformation ways to change their administrative systems, which has different management system and operation pattern. At the same time, the transformation of county-level administrative region is also a “double-edged sword”, we should think about the administrative system as a whole to decide whether it should be adjusted, and effectively respond to the actual needs of local economic and social development.","PeriodicalId":165093,"journal":{"name":"Journal of Geographical Research","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-01-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130181349","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}

Changes in weather conditions such as precipitation and temperature result in changes in discharge. To better understand the floods and eventually develop a system to predict them, we must analyze in more detail the flow of rivers. The purpose of this article is to analyze the discharges in the upper Senegal River Basin by focusing on determining the limits of the climatic classification according to past discharges. The daily discharges from May 1, 1950 to April 30, 2018 were chosen as the study period. These flow data have been grouped into annual discharges and classified as very wet, moist, medium, dry and very dry each year.Then, the flow data were divided into two seasons or periods each year:high water and low water. The statistical variables used in this study are the average, the standard deviation, the coefficient of variation and the skewness. The results of the climate classification that corresponds to a log-normal distribution indicate a total of 17 years classified as averages (25% of the series), 14 classified as wet (20.6%), 29 classified as dry (42.6%) and 8 classified as very wet (11.8%), very dry classifications being nil.Seasonal analysis showed that the months of the high water period, such as September, had the highest flow, and the period of low water, such as May,had the lowest flow. The results of the flow analysis were then compared with changes in rainfall. The results obtained show similar climatic classifications between rainfall and flow in the basin.","PeriodicalId":165093,"journal":{"name":"Journal of Geographical Research","volume":"77 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-01-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114808899","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}

Data on RTIs were collected from the Hospital Management Boards of the Ministries of Health of Rivers, Bayelsa and Delta States and the data for PM2.5 were remotely sensed from 2016 to 2019, and subsequently analyzed with ANOVA and Spearman’s rank correlation statistics. The findings of this study revealed that there was significant variation in the occurrence of PM2.5 across the selected urban centres in the Niger Delta Region. The PM2.5 for the reviewed years was far above the World Health Organization (WHO) annual permissible limit of 10 µg/m3 thereby exacerbating Respiratory Tract Infections (RTIs).The epidemiology of the RTIs showed that there are basically four (4) prominent RTI diseases: Asthma, Tuberculosis, Pneumonia and Chronic Obstructive Pulmonary Disease (COPD). The result of this study showed that the concentration of PM2.5 varies in all the selected cities, and the mean monthly variation (2016-2019) showed that Port Harcourt had 47.27 µg/m3 for January while Yenagoa and Asaba had 46 µg/m3 and 47.51 µg/m3 respectively for January; while the lowest mean value in the cities were seen within the month of September and October, which also had a strong seasonal influence on the concentration of PM2.5. The concentration of PM2.5 and the numbers of RTIs also gradually increases in the study areas from 2016 to 2019.

Then, in synthesising Bauman’s vision of contemporary society as that moving from seemingly well-ordered stabilities to a geographic realm where change is the-only-permanence and uncertainty the-onlycertainty, the manuscript generates five lead propositions calling for 'plural knowability',viz.,for a deeper/richer palette-of-imagination on the teeming multiplicities and throbbing provisionalities of culture as it emerges/unfolds or otherwise gets recast under the destabilising 'nomadic logics' of our time. In viewing culture as a vehicle of both 'impermanence' and 'seduction nowadays, the paper notes how in so many places and spaces, individuals are less inclined to be engaged locally/regionally/nationally as culture —partly through the volatile iterability of travel/tourism — has become an ever-widening polylogue.","PeriodicalId":165093,"journal":{"name":"Journal of Geographical Research","volume":"50 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-11-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132013024","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}

Monitoring is needed in order to guarantee the quantity and quality of stored water. However, this task is sometimes not easy. The objective of this study was to develop a procedure for predicting volume of stored water with remote sensing in water bodies under Mediterranean climate conditions. To achieve this objective,multispectral Landsat 7 and 8 images (NASA) were analyzed for the following five reservoirs: La Serena,La Pedrera, Beniarrés, Cubillas and Negratín (Spain). Reservoirs water surface was computed with the spectral angle mapper (SAM) algorithm.After that, cross-validation regression models were computed in order to assess the capability of water surface estimations to predict stored water in each of the reservoirs. The statistical models were trained with Landsat 7 images and were validated by using Landsat 8 images. Our results suggest a good capability of water volume prediction from free satellite imagery derived from surface water estimations. Combining free remote sensing images and open source GIS algorithms can be a very useful tool for water management and an integrated and efficient way to control water storage,especially in low accessible sites.","PeriodicalId":165093,"journal":{"name":"Journal of Geographical Research","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116629893","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}

Incorporating the old and in many cases, the materialities of the past through a reconsideration of heritage to the future of rural space requires an adequate conceptualization and reconsideration of rural materialities and especially of popular housing. In this way, it is intended to decentralize the human and functionalist point of view to give a life of their own to rural cultural and natural materialities in the context of more-thanhuman-geographies. The renewed study of heritage and the historical past acquires a notable value in the present and future of rural areas through: (1) the interpretation of dissymmetrical realities where the old confronts new activities; (2) for adequate and realistic management of rural heritage and the processes of selective recovery of heritage in certain historical places.","PeriodicalId":165093,"journal":{"name":"Journal of Geographical Research","volume":"81 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128345370","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}

This paper examined the gendered perceptions of climate variability and change among local communities in Queen Elizabeth National Park in Uganda.The objectives are threefold: - identify climatic shocks faced by the local communities; examine the perceptions of men and women of climate variability and change; and to compare their perceptions with empirical meteorological data. This study employed both qualitative and quantitative methods, with data collected from 215 respondents using survey, interviews and focused group discussions. From the findings, indicators of climate variability and change included reduced flooding events, occurrence of human diseases, increasing crop pests and diseases, dry spells and intensity of rains. There was increasing significant temperatures while rainfall was declining. Both male and female significantly associated with increasing temperatures and reduced flooding events. While climatic shocks affected both males and females, the impact was more pronounced depending on distinct livelihood activities and roles and responsibilities undertaken. The study concluded that people’s perceptions of climate change should be taken on by the government and integrated in the national climate programs that support people’s livelihoods and survival mechanisms.","PeriodicalId":165093,"journal":{"name":"Journal of Geographical Research","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126066991","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}
