This study aims at the characterization of monsoonal rainfall. Daily rainfall data of four stations for the period 1981-2018 were collected from Nigerian Meteorological Agency. The Intraseasonal Rainfall Monitoring Index (IRMI) was generated and used in determining the RODs and RCDs. The Mann-Kendall test was used to detect trends of the rainfall characteristics. Wavelet transform was used in modelling RODs and RCDs. Findings revealed that RODs vary between stations. There is low (0.3 Spearman's Rank r) correlation between latitudes and Early Cessations (ECs) of rains. The Morlet wavelet analysis revealed that from 1999 to 2018, there were more of EOs and NOs especially in Kano station. We conclude that from 1981 to 2018 there has been a minimal increase in the retreat dates of rainfall in the study area.

Hydrogeologically, the specific capacities recorded from different areas within this Basin vary from 6700 lit/hr/m to 13,500 lit/ hr/m. The water table is very close to the ground surface and varies from 0 to 4 meters. Unconfined groundwater aquifers occur in shallow unconfined aquifers, sands of the coastal beach ridges and river point bars, and sandy islands within the mangrove belt. There is a stable water table fluctuation which characterised the high precipitation zone. The shallow aquifers of Benin Formation are more porous than those in the Deltaic areas. In the southern areas, along the coastal zone, an artesian condition occurs. However, the aquifers are less transmissible with increased depth of the confined aquifer, owing to its more delicate texture. Therefore, more compact, and less permeable, or that there is not enough water in storage. More than half of groundwater sources in the Basin are acidic. Based on mean TDS concentration groundwater, fall in an excellent class for drinking. Groundwater classification based on conductivity showed all the reported findings indicate conductivity ranging from 250-750 μS/cm. Based on cation and anion chemistry, the Niger Delta Basin holds water of relatively acceptable drinking quality. However, the uncontrolled groundwater development, land-use changes, pollution from industrial, municipal, and agricultural effluents pose a threat to groundwater quality protection. Thus, a policy guideline is required to protect groundwater from pollution.

Daily rainfall data of four stations purposively selected namely: Gusau, Kano, Katsina and Sokoto for the period 1981-2018 were collected from Nigerian Meteorological Agency. The data were analyzed and the Intra-seasonal Rainfall Monitoring Index (IRMI) was generated. IRMI was used in determining the RODs and RCDs of rainfall and LGS and CR. The Mann-Kendall test was used to detect trends in rainfall characteristics. Findings revealed that RODs, unlike RCDs of rainfall in the study area, show extensive variations from one station to another. There is a very low correlation (0.07 coe cient) between latitudes and early onsets (EOs). There is however a strong positive correlation (0.8 coe cient) between meridians and EOs of rains. Late onsets (LOs) recognize latitudinal differences to the extent that there is strong positive correlation (0.7 coe cient) between lines of parallels and LOs of rains. The three types of onsets interchanged with one another annually without a clear trend in the RODs and RCDs phases. We conclude that non-de nite trends in RODs and RCDs pose a strong challenge to long term adaptation planning. The recommendations of the study are geared towards enhancing climate change adaptation in the context of complicated rainfall characteristics of the study area.

The categories of health facilities are Hospitals, Clinics, Maternity centers, and Dispensaries vis-à-vis their population was captured and mapped. The results of the analysis show a total of 24 health facilities in Birnin Kebbi Metropolis, eight (8) are privately owned, four (4) registered with State Ministry for Health and four (4) not registered and Sixteen (16) are publicly owned. In addition, there are three (3) secondary health care centers, the Federal Medical Center, four (4) Primary Health Centers, four (4) Post Primary Health Centers and four (4) Clinics. Our findings revealed the disproportionate distribution of health care facilities in Birnin Kebbi metropolis. The underlying reasons for this remain poorly known. A further study which will map healthcare facilities in relation to population distribution is therefore recommended. Because the identification and mapping of health facilities vis-à-vis the geospatial database creation will help decision makers plan and take a decision with complete confidence using maps.

Groundwater availability is also determined by topography, geology, and climate, accountable for numerous natural surface indicators and groundwater availability. Objective: This paper evaluates the empirical relations between geology and sporadic groundwater levels over three geographical locations in the Sokoto basin by assessing the variability of static water level, pumping test, pumping water level and estimated yields from boreholes. Method: Hydrogeological data comprising of standing water level (Swl), pumping water level (Pwl), pumping test (Pt), and estimated yield (Ey) were derived from 612 boreholes in the Basement complex section (n=103), central Sokoto basin (n=113) and western Sokoto basin (n=396). The result shows that the Swl, Pt, and Ey were higher in the central Sokoto basin, whereas, Pwl was higher in the western Sokoto basin....

With rapid population growth and urbanization most, states in Nigeria find it difficult to deliver potable water to a substantial number of people who are in dire need for this resource, especially in the Urban areas. In this study, we attempt to relate public water supply to population density in Kebbi State. An inventory of water supply facilities was taken in 21 Local Government Areas (LGAs) in Kebbi State. Census data was collected from the National Population Commission (NPC), Birnin-kebbi. Results showed that, population density correlates very strongly and positively with handpumps ( r= 0.95), urban schemes ( r= 0.88), semi-urban schemes ( r= 0.69) and village scheme ( r= 0.74). There was a very weak but positive correlation between population density and boreholes ( r=< 0.001); population density and tabs ( r= <0.001). PCA results showed, that the 21 LGA...

It presented a synthesis of hydrochemistry and a description of the hydrogeological configurations of the two basins. Hydrogeologically, most areas under Cross River and Imo-Kwa-Ibo are poor in terms of groundwater potentials. Based on the hydrochemistry, the basins hold water of excellent quality. Groundwater sources fall in soft to moderately hard classes. The entire sources groundwater has a TDS concentration of less than 500 mg/l. Groundwater classification based on electrical conductivity (EC) showed EC levels were less than 500 µS/cm. Most of the examined cations and anions are within WHO reference guidelines for drinking water quality. However, no broadanalysis of water quality based on water quality indices. Also, studies modeling pollution or the impact of land use changes on groundwater quality are wanting. Thus, further analysis of the hydr...

Five sampling locations were purposively selected, and, in each point, three samples were taken from surface water (river).The sampling was repeated after 20 days. Thus, a total of 30 samples werecollected. Water samples obtained were subjected to laboratory tests. Results revealed that BOD, TDS, Mg2+, and Fe3+ are above the World HealthOrganization (WHO) and Standard Organization of Nigeria (SON) reference guidelines for drinking water quality. Isolates detected from the coliform bacteriological analysis include Enterobacter aerogene, Escherichiacoli, and Citrobacter freundii with most of the samples showing coliform bacteria growth above the SON standard for drinking water. Hence, the water in the River-Rima floodplain of the Wamakko area is of low quality and unsafe for drinking. Results of principal component analysis (PCA)revealed external influences such as pollutant wash off and rock...

This paper presents a thorough review of the hydrogeology and hydrochemistry of the Hadejia-Yobe basin. The hydrochemical and hydrogeological configurations as reviewed indicated that the Chad Formation is the prolific aquifer in the basin. Boreholes piercing the Gundumi formation have a depth ranging from 20-85 meters. The hydrochemical composition of groundwater revealed water of excellent quality, as all the studied parameters were found to have concentrations within WHO and Nigeria’s standard for drinking water quality. However, further studies are required for further evaluation of water quality index, heavy metal pollution index, and irrigation water quality. Also, geochemical, and stable isotope analysis is required for understanding the provenance of salinity and hydrogeochemical controls on groundwater...

It is service industry task with the role of commuting passengers and their light freight across a geographical space. The full weight of the transportation medium was exerted on the study area with the ban of motor cycle operations. It forms part of many socio-economic activities taking place in Maiduguri. Multi stage sampling techniques were used in collecting the primary data. Maiduguri was stratified into densely, moderately and sparsely populated areas. Table of random numbers guided selection process of sample from stratum after mapping the existing Tricycle stations. The primary data were obtained through interview schedule, observation as well as trip count. The respondents were also selected systematically at regular defined interval. Findings were analysed using descriptive statistical tools. It was revealed that the operation of Keke Napep come into effect in full pledge with the ban of Motorcycle as a means of transportation in Maiduguri. It absorbs large number of productive male gender into the trade as operators while the females only surfaced as owners of the vehicles. It is par with other economic activities in terms of employment and income generation. The operation of the new medium of transportation was hindered to larger extent by the insecurity bedevilling the state. In addition to the security threat, double and over taxation were also forces of retardation.

Water samples were drawn from shallow groundwater (hand-dug shallow wells < 5 m) and deep groundwater (boreholes > 40 m). Physical parameters (i.e., temperature, TDS, pH, and EC), were determined in situ, using handheld meters. Discrete water samples were obtained for determination of chemical parameters. Results from several-sample ANOVA (Kruskal–Wallis test) suggested that heterogeneity in water table appeared to exert significant influence on groundwater chemistry which is characterized by a significant difference in pH, EC TH, Na+, Zn2+, Mg2+, PO43−, Cl−, HCO3−, SO42−, and NO3− concentrations. Also, ions including Fe3+, Zn2+, Mg2+, Na+, PO43−, and SO42− are above World Health Organization (2011) and National Standard for Drinking Water Quality (2007) reference guidelines. Most of the groundwater sources are moderately hard...

This led to the practice of open dumping system, which is not environmentally sound and socially acceptable. Considering the nature of solid waste disposal in Nigeria, there is a need to utilize techniques and technology for effective decision making in selecting appropriate site for solid waste disposal. This aim of this paper lies in management of waste at its final destination or dumping grounds with the objective of locating the most suitable site for municipal solid waste disposal in Birnin Kebbi. Remote Sensing technology and Geographic Information System Multi-criteria evaluation method were employed to perform effective site suitability analysis of the study area. Landsat 8 OLI was used to generate needed data for this research. Buffer distance analysis and overlay operation were used to evaluate site suitability criteria considered for this research. The result achieved in this study generated maps that shows better site for urban solid waste disposal/landfill in Birnin Kebbi; these may help in finding a better approach to curtail the current challenges.

Kano been one of the most populous cities in Nigeria, is undergoing tremendous urban expansion particularly at the edge of the city. This expansion could be attributed to not only population growth but also redistribution of activities within the metropolitan area. Rapid population growth has increased the tendency of cities in developing countries to outgrow the resources of the economies they are supposed to nourish and support. This confounds the planning problems faced by planners and urban managers thereby degrading the urban fabric. Data for this study was obtained through the administration of questionnaire to planners and urban managers in metropolitan Kano. The study discovers that the myriad of planning problems in the study area emanates from the fact that government and planners are incapable of handling the efficient provision of basic infrastructure and amenities and the situation of poverty n...

The problem of housing has become an everyday discussion in all quarters of the public and private sectors of the African countries. It has became glaringly clear that most of the urban population lives in dehumanizing housing environment while those that have access to average housing do so at a very high cost. The expensive nature of housing compels low income and middle income earners to resort to live in dilapidated housing and structures that are often congested and unfit for normal liveability. Provision of housing requires huge capital outlay and the financial requirement on the part of the developers both in the private and public sectors for the provision of housing is to say the least enormous. The major problem confronting planners and urban managers is the emergence of slums and shanty towns which are solely fuelled by th...

Kano been one of the most populous cities in Nigeria, is undergoing tremendous urban expansion particularly at the edge of the city. This expansion could be attributed to not only population growth but also redistribution of activities within the metropolitan area. Rapid population growth has increased the tendency of cities in developing countries to outgrow the resources of the economies they are supposed to nourish and support. This confounds the planning problems faced by planners and urban managers thereby degrading the urban fabric. Data for this study was obtained through the administration of questionnaire to planners and urban managers in metropolitan Kano. The study discovers that the myriad of planning problems in the study area emanates from the fact that government and planners are incapable of handling the efficient provision of basic infrastructure and amenities and the situation of poverty n...

The problem of housing has become an everyday discussion in all quarters of the public and private sectors of the African countries. It has became glaringly clear that most of the urban population lives in dehumanizing housing environment while those that have access to average housing do so at a very high cost. The expensive nature of housing compels low income and middle income earners to resort to live in dilapidated housing and structures that are often congested and unfit for normal liveability. Provision of housing requires huge capital outlay and the financial requirement on the part of the developers both in the private and public sectors for the provision of housing is to say the least enormous. The major problem confronting planners and urban managers is the emergence of slums and shanty towns which are solely fuelled by th...

The focus of the paper is on the frustrations and challenges ordinary Nigerians encounter in the course of having access to land. The 1978 Land Use Decree was promulgated to ensure easy access to land in Nigeria but it has left the people worst off. It is the contention of this paper that majority of Nigerians do not have easy access to land allocation from the government and the only option available to them is to resort to acquiring land from the informal land market. Similarly, the general consensus of the Nigerians is that they have not been treated fairly by the government as far as access to land is concerned. The paper concludes by recommending ways to enhance easy access to land to ordinary Nigerians in order to ensure equity and fairness in allocation of such a vital societal resource.

One of the major causes of climate change is the use of fossil fuel which leads to increase in the quantity of greenhouse gases in the atmosphere. Kano city just like other parts of the Nigerian nation has been experiencing serious power outage thus necessitating the populace to resort to the use of generators despite the imminent danger this poses to the climate. A total of 289 households were sampled via a combination of purposive and systematic sampling techniques. The major finding of the study reveals that the inability of Power Holding Company of Nigeria (PHCN) to provide electricity in sufficient quantity compels people to resort to the use of generators which was considered cheaper and handy than other energy sources such as wind and solar that are very expensive to acquire and maintain. Another interesting finding is that majority of the sampled respondents do not even know the effect of using generators and its likely impact on the climate. The study concludes by recommending ways to sensitise the populace on the imminent danger of generator usage to the environment and the need to resort to other sources of energy.
