Public-Private Partnership Arrangement in <i>In-Situ</i>Housing for Slum Rehabilitation in Yenagoa, Bayelsa State, Nigeria

The provision of decent accommodation is a major challenge to government in the developing nations. It is a common phenomenon in the urban centres of the developing nations where most houses are in deplorable conditions. The houses are overcrowded with little or no air space between them. There is no basic sanitation in the urban centres as they lack flush toilet, some of the few available flush toilets are piped into seasonal streams, most houses lack defined kitchen areas and healthy sewage disposal method. The cities lack good access roads and functional drainage system with a common practice of environmentally-unfriendly solid waste management methods that create various health challenges to urban dwellers. The aim of the study is to show how in-situ Housing method of slum rehabilitation can be applied through Public/Private Partnership to upgrade houses within a major slum area in Yenagoa. This shall be done with an agreement between the property owners, Real Estate investors and the state government. Basic Research Methodology was applied using questionnaire, direct observation and personal interview techniques to collect data. Both qualitative and quantitative techniques were applied to analyse data through the use of tables and charts. The findings in the study showed that poor housing condition seriously degrade the environmental quality of the study area. The standard of living in the area is very poor as the people lack access to decent accommodation, basic sanitation and social amenities.

Parasites Status of Village Chickens (<i>Gallus gallus domesticus</i>) in Selected Communities in Yenagoa Local Government Area of Bayelsa State, Nigeria

Parasites constitute a major obstacle to poultry production, leading to significant losses in many poultry farms. This study investigated the parasites status of village chicken (Gallus domesticus) collected from selected communities in Yenagoa Local Government Area of Bayelsa State Nigeria, during January to March 2020. A total of 35 birds were collected from 5 communities: Igbogeni, Tombia, Agudama, Akenfa and Opolo to assess their parasitic status. The procession of the chicken and the identifications of both ecto and endo parasites followed standard techniques. From the results, the prevalence of the ecto parasites and the endo parasites in the chickens were 85.71% and 88.57% respectively. The ectoparasites species in order of increasing frequency were Lice (37.65%), Fleas (32.94%), and Mites (29.41%). Mixed infection of lice & fleas accounted for 34.12%. The prevalence of endo parasites was: Nematode (71.59%) and Cestode (28.41%) respectively. The species specific prevalence of the endo parasites encountered were Ascaridia galli (44.4%), Heterakis gallinarum (22.2%), Capillaria spp. (33.3%), Davainea proglottina (56%), Raillientina spp. (44%) respectively. This present study has provided an insight into parasitic infection of domestic birds across communities in Yenagoa Local Government Area of Bayelsa State Nigeria and recommended that an intensive health education on their public health implications in the spread disease causing pathogens among humans be carried out.

Analysis of Shoreline Changes in Ikoli River in Niger Delta Region Yenagoa,Bayelsa State Using Digital Shoreline Analysis System(DSAS)

The use of Digital Shoreline Analysis System was used to determine shoreline changes in Ikoli River,Yenagoa,Bayelsa State.Shoreline data were extracted from satellite imagery over thirty years(1991-2021).The basis of this study is to use Digital Shoreline Analysis System to determine erosion and accretion areas.The result reveals that the average erosion rate in the study area is 1.16 m/year and the accretion rate is 1.62 m/year along the Ikoli River in Ogbogoro Community in Yenagoa,Bayelsa State.The mean shoreline length is 5.24 km with a baseline length of 5.2 km and the area is classified into four zones to delineate properly area of erosion and accretion based on the five class of Linear regression rate,endpoint rate and weighted linear rate of which zone Ⅰ contain very high erosion and high erosion with an area of landmass 255449.93 m^(2) of 38%,zone Ⅱ contain moderate accretion,very high accretion and high accretion with a land area of 1666816.46 m^(2) with 24%,zone Ⅲ has very high erosion and high erosion with an area of landmass 241610.85 m^(2) of 34% and zone Ⅳ contain moderate accretion and high accretion with land area 30888.08 m^(2) with 4%.Out of the four zones,zone Ⅰ and Ⅱ were found to be eroding with 72% and zone Ⅱ and Ⅳ contain accretion with 28%.The result shows that 44% of the area have been eroded.Therefore,coastal engineers,planners,and shoreline zone management authorities can use DSAS to create more appropriate management plans and regulations for coastal zones and other coastal parts of the state with similar geographic features.

Geoelectric Sounding for the Determination of Aquifer Transmissivity in Parts of Bayelsa State, South South Nigeria

The application of geophysical methods in combination with pumping tests provides a cost-effective and efficient alternative to estimate aquifer parameters. In this study, nineteen Schlumberger vertical electrical soundings (VES) were occupied in parts of Bayelsa State using a maximum current electrode separation ranging beweeen 300 - 400 m with the aim of estimating the transmissivity of the alluvial aquifer in areas where no pumping test has been carried out. Four of the soundings were carried out near existing boreholes in which pumping test had been carried out. The VES data obtained was interpreted, and layer parameters such as true resistivities and thickness were determined. The geoelectric parameters were used to generate the Dar Zarrouk parameters. Correlating the Dar Zarrouk parameter (e.g longitudinal unit conductance) with transmissivity derived from pumping test data, a constant was found which translate longitudinal unit conductance to transmissivity in a hydrogeological setting where effective porosity is the primary control on resistivity and hydraulic conductivity. Transmissivity determined from the pumping test data range between 1634.0 - 5292.0 m2/day while transmissivity values estimated from the longitudinal unit conductance (Lc) range between 721 - 8991 m2/day. The transmissivity estimated from the pumping test (Tp) data and transmissivity estimated from the longitudinal conductance (Lc) on comparison show excellent correlation (R2 = 0.92). The high transmissivity values agree with the geology of the Benin Formation (Coastal Plain sands) consisting of fine-medium-coarse sands. The results give a useful first approximation of the transmissivity and could be used to site exploratory boreholes.
