  • COVID-19 Vaccination Acceptance and Its Associated Factors: Insights from
           Rural and Urban Settlements in the Yilo Krobo Municipality in Ghana

    • Authors: Louis Kusi Frimpong, Shine Francis Gbedemah, Fatimah Eshun, Paulina Okine, Araba Mbrowa Korsah
      Pages: 1 - 27
      Abstract: The introduction of COVID-19 vaccines is viewed by many as an important milestone in controlling the spread of COVID-19 and a critical step toward attaining the required threshold for head immunity. However, accepting a vaccine is key to a successful rollout of any vaccination programme. Using the Strategic Advisory Group of Experts on Immunization (SAGE) framework on vaccine acceptance and hesitancy as an analytical framework, this study examines COVID-19 vaccination acceptance and its associated factors in rural and urban settlements in the Yilo Krobo Municipality in Ghana. Data for the study were drawn from a cross-sectional survey conducted in an urban and three rural settlements in the Yilo Krobo Municipality. The findings showed that about 97% of residents were aware of the COVID-19 vaccine rollout exercise in the country; however, only 46% were willing to take the vaccine. The results from the binary logistic regression show that the sex of respondents (p<0.01), safety considerations (p<0.001), level of information on the vaccine (p<0.05), and perceived risk concerns (p<0.01) were the key factors that significantly influenced vaccine acceptance in the municipality. The study recommends more public education and sensitization to reduce misconceptions and increase trust in the vaccine rollout exercise.

  • Perceived Effects of Rainfall and Temperature Variability on Yields of
           Cereal Crops in the Mion District of Northern Ghana

    • Authors: Alhassan Shirazu, Dzigbodi Adzo Doke, Abdul-Kadri Yahaya
      Pages: 28 - 54
      Abstract:  Climate variability has been a major threat to achieving sustainable food production in many countries, including Ghana. This is attributable to insufficient and erratic rainfall coupled with increasing temperature. This study examined the perceived effects of rainfall and temperature variability on yields of cereal crops in the Mion District of the Northern Region. The study reveals that farmers in the Mion District have experienced changes in climatic conditions evident in high temperatures and low rainfall. The study also reveals that rainfall and temperature variability adversely affect the yields of cereal crops such as rice, maize, and millet. The effect could manifest in either yield reduction or total crop failure of cereals. The study also showed that factors that enable farmers to respond to impacts of rainfall and temperature variability are Agric extension services, application of fertilizer, irrigation farming, use of improved seeds, and favourable government policies such as subsidies and credit facilities.   The study, therefore, concludes that yields of cereal crops are adversely affected by rainfall and temperature variability. However, farmers resort to Agric extension services, application of fertilizer, irrigation farming, use of improved variety of seeds, and favourable government policies in response to the impacts of rainfall and temperature variability. The study recommends that government should employ more extension agents and construct more irrigation facilities in the Mion District to reduce the adverse effects of climate variability on yields of cereal crops.

  • Environmental and Socio-Economic Impact Assessment of Solid Waste
           Management Practices in Mbale city, Uganda

    • Authors: Remigio Turyahabwe, Joyfred Asaba, Andrew Mulabbi, Emma Wamono, Paul Makoba Gudoyi
      Pages: 55 - 89
      Abstract: This study assessed the environmental and socio-economic impact of waste management practices in Mbale city. We used questionnaires, interviews, focused group discussions and field observations to collect the required data, which was analysed using basic descriptive statistics and Chi square test (χ2).  Results indicate that, the solid waste management practices employed in Mbale City resulted into degradation of air quality (P<0.001), water quality (P<0.001) and land (P<0.101). Socio-economic analysis indicated that costs of waste management practices outweighed the benefits. The management practices were associated with severe health issues to the households living near dumpsites and waste management employees, although revenue and employment opportunities were also created in some instances in remote areas of the city there is limited sorting of hazardous from ordinary wastes that have come with associated effects on the environment. A conclusion was reached that, despite employing many citizens, the present solid waste management practices in Mbale City responsible for injuries incurred by scavengers (waste collectors), land and air quality degradation as citizens lack knowledge of proper waste management systems. Therefore, City authorities should sensitize the masses on best waste management practices like sorting and recycling and provide incentives for collection, sorting and assemblage of recyclable non-biodegradable wastes.

  • Need for Emergency response to Wetlands Loss in Southwestern Nigeria: A
           Review

    • Authors: Benjamin Oluwafemi Adeleke
      Pages: 90 - 114
      Abstract: Southwestern Nigeria's wetlands are assaulted, degraded, and lost, especially to agricultural development and urban expansions, while the rural wetlands losses are due to agriculture but temporal in nature, loss to urban developments are permanent. To examine the extent, influence, and potential of the degradation, the review covered the six states of the region, revealing losses due to wetlands destruction in the region between 1965 and 2019. Wetlands in Lagos reduced from 708.96ha (52.68%) in 1965 to 7.10ha (0.53%) in 2005, Eleyele Wetland in Oyo State, (Riparian), reduced consistently from (1.25 km2) in 1984 to (0.98 km2) 1994, (0.70 km2) 2004 and finally (0.42 km2) in 2014. Eriti forested wetlands of Ogun State lost about 45.32% between 1972 and 2015; in Ondo State, Akure South Local Government Area Wetlands decreased from 98.90 km2 (30.13%) in 1999 to 90.33 km2 in 2009 (27.52%); Ilesa wetlands, in Osun State decreased from 258 hectares to 89 hectares between 1986 and 2002. The above scenarios in the region imply that in a short while, the wetlands would be completely lost, most importantly to the uncontrolled urban developments. Therefore, there is an urgent need for all hands to be on deck to protect wetlands by considering them as endangered ecosystems.

  • Combining Remote Sensing and Space-Time Analysis for Desertification
           Monitoring in the Semiarid Dryland of Nigeria

    • Authors: Olanrewaju Lawal, Adeniyi Sulaiman Gbadegesin
      Pages: 115 - 144
      Abstract: Desertification has been identified as the resultant effect of dryland loss. Desertification is catalysed by anthropogenic modifications and variations in environmental/climatic conditions. The situation in Nigeria is further exacerbated by the growing demand for land by the population. To this effect, this study performed a space-time analysis of vegetative cover between 2001 and 2020 to unravel patterns and trends across the semiarid region of the dryland system in Nigeria. The dynamics during the rainy season (May and September) were examined using the Terra Moderate Resolution Imaging Spectroradiometer (MODIS) dataset subjected to space-time analysis. Generalised Difference Vegetation Index (GDVI) was computed to the power of 2 to quantify vegetative cover across the study area. The results showed that the average of the GDVI ranges between -0.40 and 0.94, with a standard deviation of 0.11. Time series cluster analysis revealed that there are two temporal clusters: (1) no statistically significant trend (Statistics= 1.33, p-value = 0.18) and (2) statistically significant downtrend (Statistics = -2.37, p=0.02), with cluster 1 covering 95% of the areas examined. The most dominant (97% of the area) emerging space-time pattern was cold-spots (persistent, diminishing, sporadic, oscillating, and historical types). In conclusion, most of the areas showed no definite temporal pattern of vegetation pattern during the period, while more than 90% of the areas have witnessed a decline in vegetative cover. There is a need for a more coordinated approach to desertification control, constant monitoring is pertinent while new approaches to restoring degraded land are recommended.

  • The Influence of Fadama Activities on Women Empowerment in Ede North Local
           Government Area of Osun State, Nigeria

    • Authors: Martin Binde Gasu
      Pages: 145 - 174
      Abstract: The study was conducted to assess the influence of Fadama activities on women empowerment in the Ede North Local Government Area of Osun State, Nigeria. Primary data were obtained purposively with the use of 240 structured questionnaires in a survey of 24 Fadama Users Groups (FUGs) whose representatives constitute 6 Fadama Communities Associations (FCAs) in the study area. Secondary data were, on the other hand, obtained from existing literature. Data were analyzed with the aid of Statistical Package for Social Sciences (SPSS) to obtain both descriptive and inferential statistics. The findings show that 58.8 percent (mostly women) were into agro-processing, 25.4 percent into farming, 12.5 percent into poultry, and 2.9 percent were into fish farming. The results further show that only 16.25 percent of the respondents received an average monthly income of N29.000-N39.000, 4.16 percent received above N40.000 before the commencement of the program. After the program, 45.00 percent now earned an income of N29.000-N39. 000 while 42.08 percent earned above N40. 000. The result of the factor analysis reveals that the total variance explained by each component extracted made up to 69.61 percent of the total variance, with variable one gender explaining 31.34 percent. The findings from the study revealed that the Fadama program in Ede North Local Government increased the participation and income of rural women farmers in agricultural production, which has helped in reducing the problem of gender discrimination.  This trend, we assume, could reduce poverty and advance the success of Sustainable Development Goals (SDGs).

  • Flood Risk and Flow Variability Assessment at the Railway Drainage
           Structures: A Case of the Ethio – Djibouti Railway Line, Ethiopia

    • Authors: Habeeb Solihu, Belete Berhanu Kidanewold, Abdulwasiu Abdulkadir
      Pages: 175 - 210
      Abstract: Awash River Subbasin is one of the major river flood-prone areas in Ethiopia where the most significant part of the railway section is constructed. There is tendency of this railway line being affected by flooding. The study performed the flood risk analysis and flow variability at some selected drainage structures within Sebeta and Adama Section of this line. The climate and observed flow data were sourced from the National Meteorological Agency of Ethiopia and the Ministry of Water, Irrigation and Energy of Ethiopia respectively, and used for hydrological model parametrization, calibration, and validation. DMC, Linear Regression, and Thiessen Polygon were used for climate data consistency check, filling of missing data, and estimation of areal data respectively. The rainfall-runoff was simulated with an HEC-HMS hydrological model using a 20years (2000 – 2019) rainfall data. The model calibration and validation results using NSE, PBIAS, and R2, were found within the statistically acceptable range for the surface runoff simulation. This study developed Rainfall Intensity – Duration Frequency Curve for the selected catchment as an input for the flood frequency analysis in the model. The coefficient of variance was estimated to select the flood discharge structures with the flow variabilities. The flood risk was assessed by comparing the modeled and the as built designed Q100 (m3/s) extracted from the design documents. About 46% of the drainage structures are found prone to flooding at a T100years. This study recommends the use of the methodological procedure adopted in this study for other section of this line by other researchers.

  • Assessing Community Coping Strategies in Sustainable Flood Management. A
           Case Study of Kaemibre and Walantu in Kasoa

    • Authors: Kwabena Awere Gyekye, Philomena Kafui Darko
      Pages: 211 - 251
      Abstract: Community based flood management has become fundamental in increasing societies’ resilience to flooding. As climate change and urbanization continue to worsen flood disaster events, it is practical to examine local adaptation to floods. To achieve this objective, multi criteria analysis, using Geographic Information System and Digital Elevation Model for flood modelling and risk mapping assessment, buttressed by questionnaires, was employed to evaluate human relationship and response to flood risks management. A landuse map of Satellite remote sensing Level 1B satellite images from Landsat ETM Plus for the month of October 2018 was created, using Environment for Visualising Images Software and Geographic Information System for estimating changes in the land cover during the modelling process. The most affected communities were defined from the overlay of the risk map on the topographic map of the same scale. It was revealed that even though flood risk map shows communities’ risk of flooding, socio-economic and cultural factors play major role in flood risk management. The coping strategies of the affected communities involved bolstering walls and increasing compound elevation above flood level, desilting drains, and changing jobs. The study recommends the integration of flood hazard maps into sustainable flood management of communities.
