“…Furthermore, differences in the prevalence of malaria infection among the pupils also reflected the different study area variables (Table 4). The significantly (p=0.000) higher prevalence of the disease noted among pupils from Billiri (21.5%) and Shongom (28.7%) LGAs and generally among children in the southern senatorial district (25.1%) may not be unconnected with the fact that these areas lie within the more humid and vegetative southern Guinea savannah where favourable environmental factors for the breeding of vectors (female anopheles mosquitos) abound and hence the likelihood for higher transmission of the parasites (p. falcifarum) [10,11]. Additionally, pupils from publicly owned schools had significantly (p=0.000) higher prevalence and were about 5 times more at risk of malaria infection than their counterparts in the private schools (18.2% vs. 4.1%).…”

“…Based on climatic differences Gombe state can be divided into three zones that approximately squares with the three senatorial districts, namely; Southern Guinea Savanna (SGS) in Gombe south, Northern Guinea Savanna (NGS) in Gombe central and Sudan Savanna (SS) in Gombe north [10]. About 85% of the rainfall pattern observed in Gombe state approximately spans through April to October, but are heaviest in July, August and September [11]. These geographic variables that characterize different parts of Gombe are also known to affect the pattern of distribution of malaria infection in such settings [2,4,5,6].…”

Background: As a foremost disease of public health significance, malaria has wrecked untold havoc among children and pregnant women in developing countries with Africa and Nigeria being worst affected. Objective: This study was aimed at documenting the prevalence and socio-demographic differences in the pattern of malaria infection among asymptomatic primary school children in Gombe state, Nigeria. Methodology: Using a cross sectional study design 745 pupils aged 6 to 15 years were assessed from March to June 2019. The subjects were selected from 12 public and 6 private schools in 6 Local Government Areas (LGAs) of the state, using multi-stage sampling technique. Malaria rapid diagnostic test (mRDT) kits were deployed in screening the subjects for malaria parasites positivity or otherwise. Data was analyzed using IBM SPSS version 21 analytical software. And the findings were presented in tables and charts. Proportions were compared using chi square, with alpha significance level set at 0.05. Results: The mean age of the participants was 9.96±2.26 and 379 (50.9%) of them were boys while the rest 366 (49.1%) were girls (about 1:1 male-female sex ratio). A total of 101 (13.6%) of the 745 school children screened yielded positive to malaria rapid diagnostic test (mRDT), with children from the public primary schools being significantly (p=0.000) more affected than their counterparts in the private schools (18.2% vs. 4.1%). Though male children were more affected by malaria, the difference was not statistically significant (15.0% vs. 12.0%, P=0.229). Similarly, significantly higher proportion (p=0.000) of pupils from the rural schools were affected and were about three times more at risk of malaria (OR=3.362, CI: 2.169-5.212) than their urban counterparts (22.4% vs. 7.9%). Low academic performance was found to be associated with malaria infection (p=0.012). Other socio-demographic factors associated with malaria infection among the pupils include; senatorial district, family size, source of parental care, tribe etc. However, from the evidence of this study there was no significant association between the prevalence of malaria infection and birth order, age group and gender of the school children. Conclusion: In view of the high and disproportionate distribution of the burden of malaria among the subjects, it is hereby recommended that concerned authorities should include primary schools in the design and implementation of malaria control/ elimination programmes.

“…The average annual rainfall total is about 850 mm. The concentration of rain in these three months (July to September) has the potential of increasing the soil moisture condition, reducing infiltration capacity and hence causing flooding (Abashiya et al, 2017). The mean maximum monthly temperature is about 35 o C while the mean minimum monthly temperature is about 18 o C with relative humidity of about 95% in August.…”

Urban flooding has become a monumental yearly disaster in many of the world’s cities and Gombe town in particular. This paper focused on some hydro-geomorphological characteristics that influence flooding in Gombe town. Statistical methods and geographic information techniques were used for the assessment. The result revealed that the highest API of 166.62 mm occurred on the 5/9/2014. The rainfall amount was 92.5mm for a duration 48 minutes, average rainfall intensity was 115.63, stage height (1.42m), average flow velocity (0.98m/s), and instantaneous discharge of 9.47m3 /s. This corresponds with the flood disaster that occurred in Gombe town on the same date (5/9/2014). On the other hand, the least API of 18.12 mm occurred on the 18/6/2014. The rainfall amount was 1.2mm for 62 minutes, average rainfall intensity was 1.16, stage height (0.30m), average flow velocity (0.24m/s), and instantaneous discharge of 0.49m3 /s. findings also showed that very steep slope covered 2.4537km2 (1.78%), steep slope covered 3.60235km2 (2.61%), moderate slope (0.735574km2 or 0.53%), gentle slope (131.106km2 or 94.89%) and flat areas (0.259854km2 or 0.19%). The study recommended flood resilience technology, provision of adequate urban drainages and proper storm water management.Keywords: Drainage density, flow accumulation, rainfall, urban flooding

“…Due to fast population change which creates high demand for land and ensuing urban development processes, particularly the increasing number of settlements on floodplains, Gombe is one of the cities afflicted by urban flooding, making the urban poor vulnerable to flood risk (Daniel et al, 2012). There have been numerous studies on flooding in Nigeria and Gombe city, including those by Dabara et al, (2012); Abashiya et al, (2017);Daffi, 2014;Agbonkhese et al 2014;Webster et al 2014;Ejikeme et al (2015) ; Emmanuel (2016); Chan et al (2011); Biondi et al (2013); Eze et al 2018;Bamidele &Badiora, 2019 andAzua et al 2019. To influence the creation and implementation of planning and policy aimed at preventing, reducing, and mitigating the risks associated with urban flooding for sustainable urban development, none of these researchers examined the pattern of urban flood hazardscape based on physical factors (location, terrain, and rainfall) and the vulnerability dynamics.…”

In many Nigerian states, urban flooding has resulted into the death of numerous people and destruction of properties worth billions of Naira. This study examined the vulnerability dynamics and urban flood hazardscape pattern within Gombe city with a view to providing bases for policy formulation (where necessary), enforcement and decision making on flood risk reduction for enable sustainable urban development. ASTER DEM and Landsat images (2000, 2010 and 2019) was used to generate Digital Terrain Model (DTM) and impervious surface areas. Rainfall data for 2000-2018 was used to examine rainfall trend using regression analysis. The result revealed that flood hazardscape and vulnerability dynamics are largely influenced by physical and social factors. The results for vulnerability dynamics shows that as at 2000, about 1.4km2 lies on the relatively low vulnerable area,4.1km2falls within the moderate, and about 14.6km2 falls on critical area. By 2010, only about 1km2 lies on the relatively low area, 5.2km2 occupied the moderate and about 15km2was found within the critically vulnerable area. In 2019, the vulnerability dynamics depicts that about 33.4km2, impervious surface (builtup area) existed, out of which 2.8km2 lies on the low vulnerable area, 9.4km2 on the moderately vulnerable and 21.2km2 in critically vulnerable areas. It is concluded that flood hazardscape and vulnerability dynamics in Gombe city is influenced by both physical and anthropogenic factors. It is recommended that planning departments should put into consideration urban flood hazardscape maps for future development so as to reduce the risk and control future exposure flood impact.
