Solid waste management practices in an indigenous Nigerian city: a case of Alesinloye in Ibadan

Abstract: Solid waste management (SWM) is an essential urban service in every human settlement. Despite its importance, cities globally struggle to guarantee its provision even in developed countries. This study examines SWM practices in Alesinloye, Ibadan, Nigeria. A structured questionnaire prepared with KoboCollect was used to interview 182 households using a convenience sampling technique. Findings revealed that households are predominantly married youth with formal education and largely from the Yoruba ethnic group. It further established that food constitutes the leading solid waste component in households. The food waste, along with other waste materials generated, was disposed of mixed because there is no waste sorting system. The households mainly adopt unhygienic and unsustainable approaches such as disposable polythene bags and open space to store solid waste generated temporarily. The private waste firm was primarily responsible for solid waste collection using door-to-door (kerbside) methods in providing its service. The solid waste collection is mostly executed weekly, and the majority of the households consider it suitable. The households paid users’ charges of between ₦500 ($1.09) and ₦ 2000 ($4.35) monthly, and the variations were attributed to mainly waste quantity. While 75.2% of the households expressed satisfaction with users’ charges on solid waste services, 78.6% were unwilling to pay more for improved services, thus indicating the value placed on environmental quality. Finally, the study recommends the establishment of a SWM system towards zero waste community; the establishment of a waste management committee to serve as environmental stewards; the intensification of public campaigns and awareness of the importance of sustainable SWM, and the resuscitation of the Alesinloye recycling plant.

Environmental potential of Aedes Aegypti Mosquitoes for Dengue haemorrhagic fever in Pekanbaru, Indonesia

Abstract: Dengue fever is frequently considered a common fever, and this misconception carries the highest risk of fatality. Dengue haemorrhagic fever is still one of Riau Province’s unsolved diseases. This is one of the reasons why this study is necessary to identify prospective mosquito environmental zones with major significance for understanding epidemic transmission in the Pekanbaru City area. The bivariate statistical approach was employed in this research. The aim is to link environmental physical factors to data on the occurrence of dengue haemorrhagic fever in Pekanbaru City. The area under the curve for the correlation between the environment and the distribution of dengue haemorrhagic fever was 0.76 for the rainfall parameter, with 0.68 for the area under the curve derived from the air humidity parameter. The establishment of six environmental indicators resulted in a weight of evidence value of 10,467 to -35,693 for the mosquito’s environmental potential. Meanwhile, the most favourable potential zone, which encompasses 5,935 ha, accounts for 9.18% of the overall area. Areas with the highest risk of spreading Aedes aegypti mosquitoes were found around the city center, both residential and office areas. The risk of dengue haemorrhagic fever transmission in this zone is higher than in the other three zones. By taking earlier events into account, this knowledge can be one of the early preventions in understanding the environmental structure of the Aedes aegypti mosquito habitat.

Protected areas as recreational zones for nearby cities – the case study of the city of Vršac

Abstract: The fast-paced life has led many people to practise more frequent and shorter trips to nature. City dwellers are particularly inclined to this. Protected areas (PAs), especially those in the vicinity of cities, provide a good opportunity for one-day excursions and nature-based recreation. The paper presents the results of research aimed at determining how many city dwellers in Serbia use the surrounding PAs for this kind of activities. On a random sample of 247 residents of the City of Vršac above the age of 15, the survey method, with the help of the Statistical Package for the Social Sciences (descriptive statistics, Chi-Square Test and Kruskal-Wallis Test), confirmed the research hypothesis that the utilization of these areas for recreation purposes was insufficient. Based on this and four additional hypotheses that were tested, conclusions are drawn that will serve to define guidelines for the development of excursion tourism in the studied areas and enrich the scarce local scholarly literature on the utilization of PAs for recreation by the urban population.

The role of landscape character analysis in supporting urban tourism sites in Amman

Abstract: Historical and modern urban sites are important attraction points for the city, being considered a favourite destination for residents and tourists. The result of interaction between people and nature on these sites is the landscape, its unique character defining the identity of the place. The landscape character depends on several features, including topography, climate, biodiversity, and the site itself. The landscape character analysis gives a classification based on the characteristics and determinants of the area and highlights the natural strengths and attractions in each area. In this study, the tourism sites in Amman were chosen because of their social, economic, and historical importance as sites located in the capital city and to assess the urban landscape character and determine the function of the tourism sites in the city. To assess the landscape function of the area, an evaluation was made, considering criteria such as: Recreational Activities, Traditional Built Environment, Nature and Landscape Features, History and Heritage, Accessibility, Infrastructure, and Facilities. Score levels were given according to the intensities of the criteria in the neighborhoodsneighbourhoods within the borders of Greater Amman Municipality, as low, medium, and high according to field surveys at the sites by researchers. The desired result of the study is to make a comprehensive assessment of the importance of the landscape character in attracting tourism to Amman, identifying areas with a high density of landscapes, and drawing up a plan to capitalize on them and highlight their importance to the city.

A statistical analysis of temperature and precipitation in Belgrade, Serbia (1961-2020)

Abstract: The most significant effects of climate change are related to temperature and precipitation. Changes in precipitation and temperature patterns affect water resource capacity, agricultural activities, global biodiversity and emergency management. In this study, using two statistical models (Mann-Kendall and Pettit’s test), climate data for the territory of Belgrade in the time interval 1961-2020 were processed. Trends were analyzed: average annual temperatures, average monthly temperatures, annual and monthly precipitation amounts. The aim of the research is to determine the statistical significance of the increasing/decreasing temperature and precipitation trends on a monthly and annual basis. Based on the obtained results, it was determined that the changing point of the annual temperature is in 1997, while a statistically significant increasing trend was observed in all months except November. The increasing trend recorded by the precipitation amount is 0.345 mm/year, but without statistical significance. The most significant results corresponding to July and October.
