“…This result probably suggests that no significant improvement may have occurred in water infrastructure in many parts of the country, inspired by the increasing population and urban growth. Studies also indicated that many residents of some of the communities also seek water from hand-dug wells which often are not covered (e.g., Olajuyigbe, 2010) while more privileged residents of the urban areas may rely more heavily on machine-drilled borehole wells, protected handdug wells and rainwater harvesting (Eludoyin et al, 2007;Eludoyin et al, 2021). In the study area, machine-drilled boreholes were mostly found in newer neighborhoods but more people still depend on hand-dug wells.…”

The status of the water supplied to households in an urban local government area in southwest Nigeria was examined. Specific objectives were to characterize household water sources, assess the per capita usage of potable water sources and examine quality of the household water in the area. The purposively selected study area, Olorunda local government area in Osun State, Nigeria (being an urban local government area) was stratified into ‘urban core’ (central business district, CBD or high population density area), ‘transition’ (medium population density area but with less social infrastructure) and ‘sub-urban’ (typically government reserved area and low population density area) based on household density and associative socio-economic status. The methods were a mix of questionnaire administration to heads of 120 households (40 per stratum) and collection of the drinking water samples from the supply sources at four randomly selected households in each stratum. The water samples were analysed for the concentrations of nitrite (NO2-), nitrate (NO3-), fluoride (F-), lead (Pb) and arsenic (As) as well as E-coli bacteria contents based on their importance in determining water quality in urban areas. The results showed that domestic water sources are mainly hand dug well (55.8%), borehole (37.5%) and pipe borne (6.7%). Residents averagely consumed at most 4L of water per day. Furthermore, the investigated chemical parameters varied as NO2 (0.37-0.94 mg/l), NO3 (0.29-0.70 mg/l), and F- (0.003-0.97 mg/l). As and Pb occurred in trace quantities, and there were no pollution threats to consumers. The amount of E coli and total coliform contents were however outside the safe limits for residents, suggesting contamination of household water by the bacteria sources. The study concluded communities with low socio-economic status which do not have access to state-provided tap water source are more likely to consume polluted water than those with high socio-economic status or that are supplied with state-provided tap water. The study advocates improve urban water management for the urban fringe dwellers.

Dagiri, a community in the Gwagwalada area council, has been ravaged by floods. The most recent which took place on 25th July 2020 was devastating and had severe impacts on the community. This study focuses on the socioeconomic implication of the 2020 flood in the Dagari community. To achieve the specific objectives, a number of methodologies were employed such as map analysis, questionnaire survey, oral interviews, and site observations. Presentation of results was done using percentages, tables, bar graphs, pie charts, and photos. The land cover is mostly residential with urban infrastructures. A flood hazard map was created from which analysis revealed that about 87% of the area is at risk of flooding, though the severity of vulnerability varies from low vulnerable areas to highly vulnerable risk zones. The socioeconomic impacts were duly measured using some sustainable development indicators, and the result revealed that flooding had numerous socio-economic impacts on the community, ranging from income, education, agriculture, sanitation, infrastructures and properties. The coping strategies adopted by some community members were also very inadequate, while a high number of them are not employing any coping strategies at all. Therefore, we recommend a regulated and scientifically coordinated aggregate mining from the river and also relocation of households living in high-risk flood zones. The government should invest more in flood (disaster) management with the recent challenge of climate change.

“…The land use pattern shows the largest portion (66%) of the land built up for residential purpose while the remaining portions are shared for industrial, commercial, transportation, and educational purposes. Of these, industrial land use was the least (about 2.4% of the total land) (Eludoyin et al, 2007). Since there is few or no industry, metal contamination of topsoils may be attributed to anthropogenic activities.…”

Concentrations and pattern of Fe, Cu, Cr, and Zn contamination in the soils of Akure, Nigeria

et al. 2011

An assessment was made on twenty-eight topsoils collected from seven sites with intense artisan activities in the city of Akure, Nigeria, using geochemical approach in order to establish anthropogenic influence on metal contamination and to assess the severity of the contamination in the urban environment. Concentrations of Fe, Cu, Zn, and Cr were determined in the samples by atomic absorption spectrophotometry. The results revealed between 137-and 165-fold elevation of Fe, between 17-and 94-fold elevation of Cu, between 50-and 137-fold elevation of Zn, and between 1-and 3-fold elevation of Cr in topsoil relative to background levels. This indicates that except for Cr, soil contaminations by the metals were due to anthropic sources such as mechanic and vulcanizers workshops. The current average levels of copper exceeded the target value in Nigeria and in many developed countries, while Zn and Cr are generally lower than the respective soil quality guidelines. The contamination/pollution index maps figured out mechanic workshop as the main source of diffuse contamination and also show the influence of the point sources of contamination to urban topsoils. Cu contamination found around the soils of the mechanic/battery charger workshop is potentially serious (severe pollution), and this may pose health risk to people dwelling around these sites or within the metropolis. Children could be at greater risk than adults, because of their hand-to-mouth behaviors that increase their exposure potential.
