  • A Comparison of the Efficiency of Aquatic Macroinvertebrate Sampling Tools
           Used in Lotic Environmental Impact Assessment of Human Activities in A
           Tropical Mountain Stream in Eastern Uganda

    • Authors: Remigio Turyahabwe, Caroline Mulinya, Andrew Mulabbi, Moses Olowo
      Pages: 1 - 23
      Abstract: The study was aimed at comparing the efficiency of three macroinvertebrate sampling tools used in lotic environmental impact assessment of River Sipi including Surber sampler, rock-filled basket and Kick net sampling tools. The efficiency of the sampling tools was based on the data collected by each sampling tool, which was in turn used to calculate the Relative variation (RV) (efficiency), diversity, richness, and relative abundance, time taken to sort macroinvertebrate per sample and taxa assemblage. Data was analysed using a two-way ANOVA that was performed under the R Development Core Team 2010. The results indicated that despite the fact that all the sampling tools were efficient in sampling macroinvertebrates with RV<25%, both kick net and rock-filled basket obtained closely comparable efficiency results with Relative Variation ranging between 0.54-2% for the kick net and 1.4-3.6% for rock filled basket. Of the three sampling tools, the kick net was the most efficient, collecting a greater diversity of macroinvertebrate taxa (1.81±0.04) and a greater number of specimens (1444), abundance (66.4±0.25%), greater taxa richness (11±0.41) but required the biggest amount of time to sort macroinvertebrates (26±0.71minutes). In conclusion, the rock-filled basket served as the next best alternative efficient sampling tool to kick net in sampling macroinvertebrates.

  • Factors Affecting the Adoption of Soil and Water Conservation Practices by
           Small-Holder Farmers in Muyembe Sub-County, Eastern Uganda

    • Authors: Remigio Turyahabwe, Nabalegwa Muhamud Wambede, Joyfred Asaba, Andrew Mulabbi, Loy Gumisiriza Turyabanawe
      Pages: 24 - 49
      Abstract: Farmers in tropical rural areas are confronted with several challenges but outstanding among these
      challenges is soil degradation arising from soil erosion. This study involved identifying the dominant soil and
      water conservation practices and assessing the factors affecting their adoption in the Muyembe sub-county,
      Eastern Uganda. A total of 500 respondents were used to obtain primary data. As the study adopted a crosssectional
      design, we used questionnaires, interviews, focus group discussions and field observations to collect
      the required data. Data were analyzed using descriptive statistics and the non-parametric (Chi-square) test.
      The results indicated that the dominant soil and water conservation practices adopted in the study area were,
      contour cropping (77%), mixed cropping (59% and crop rotation (51%). The remaining five practices had
      less than a 50% adoption rate. The chi-square test revealed that the age and gender of the farmers had a
      significant association with the levels of the adoption of soil and water conservation practices among farmers
      at P<0.001. We concluded that the adoption of soil and water conservation practices was low, which left the
      majority of farmers vulnerable to soil erosion effects such as low yields and crop failure. We recommend that
      stakeholders who work on soil and water conservation programs use model farmers in the area to educate
      and demonstrate the importance of soil and water conservation practices to other farmers.

  • Spatial Analyses of Air Pollutants Concentration around the Warri Refining
           and Petrochemical Company (WRPC), Delta State, Nigeria

    • Authors: Verere Sido Balogun, Peter Akpodiogaga Ovuyovwiroye Odjugo
      Pages: 50 - 81
      Abstract: This study investigates air pollution from the Warri Refining and Petrochemical Company (WRPC) of Delta
      Sate, Nigeria with the intent of determining the variations in pollution levels associated with increasing
      distance from the refinery. The following pollutant gases: Carbon monoxide (CO), Volatile organic
      compounds (VOC), Hydrogen sulphide (H2S), Nitrogen dioxide (NO2), Sulphur dioxide (SO2) and
      Particulate Matter (PM2.5 and PM10), were monitored intermittently with the use of digital hand-held
      probes, at sampling points located between 1,500 meters to 16,000 meters from WRPC. Air sampling was
      carried out on a weekly basis, for a duration of one (1) year. The average annual concentration of CO, VOC,
      H2S, NO2, SO2, PM2.5 and PM10 measured were 0.2543 ppm, 4.4922 mg/m3, 0.0004 ppm, 0.0063 ppm,
      0.5263 ppm, 36.3825 μg/m3, 91.7346 μg/m3 respectively. The results of the spatial analyses of air pollutants
      show that concentrations of VOC, NO2, PM2.5, and PM10 shared a significant inverse relationship with
      distance (p values 0.00 ≤.0.05). The study suggests a minimum of 10,250 meters radial extent of buffers
      around WRPC, as a long-term strategy in reducing exposure of residents to air pollution. Short-term
      strategies include enforcement of legislation reducing/banning emissions from industries and bush fires, use
      of alternative eco-friendly technologies and energy sources, tree planting, revamp of the hydroelectricity
      power sector and general sanitization of the environment.

  • The Use of Family Planning Methods (FPMs) in Ilala Municipality, Dar es
           Salaam, Tanzania

    • Authors: David Msokwe, Christopher Mulungu
      Pages: 82 - 106
      Abstract: This paper examines the use of family planning methods in Ilala Municipality, Dar es Salaam, Tanzania. A
      total of 55 respondents were involved in the study. The study used both quantitative and qualitative techniques
      in collecting and analysing data. A questionnaire, in-depth interviews and documentary review were used to
      gather data. The findings indicated that the modern family planning methods, such as condoms and oral
      contraceptives like postinor-2, the morning after pills, injection, and implant, were preferred over the
      traditional family planning methods, such as withdrawals, calendar rhythm method and periodic abstinence.
      The factors influencing family planning methods were education, access to information, fear and unfounded
      ethical beliefs, number of siblings, children as an indicator of one’s high status, prestige, and children
      confirming one’s virtue. Generally, the use of family planning methods was determined by socio-economic
      status of the users and environmental variables. Therefore, it is recommended that the stakeholders construct
      health centres and educate people on good family planning methods.

  • Community Based Flood Risk Management Approach in Northeastern Uganda

    • Authors: Muhamud Nabalegwa Wambede, Robert Tweheyo
      Pages: 107 - 134
      Abstract: This study was conducted in the Amuria district of Northeastern Uganda. The aim of the study was to assess
      the performance of Community Based Disaster Risk Reduction (CMDRR) approach in mitigating disaster
      effects in the area. The objectives were to assess the effectiveness of community preparedness, response, and
      recovery efforts in mitigating disasters in the study area. Aberilela and Wera sub-counties were purposively
      selected, and two parishes were chosen from each of the two sub counties based on their vulnerability to flood
      disasters. A sample of 300 household heads were randomly selected. Methods of data collection included
      questionnaires, in-depth interviews with key informants, focus group discussions, observation, and documents
      review. The collected data were analysed using descriptive statistics and triangulated with thematic analysis
      of the data from interviews and field observations. Results from the study indicate that the CMDRR approach
      had performed well despite some shortcomings. The approach had been able to prepare the community by
      training them in disaster management activities, developing hazard prone maps, disaster plans, established
      effective rescue measures and other response measures for the affected communities. However, it had failed
      in building capacity among the communities to stock essential services including food, early warning systems
      and in detecting and predicting disaster as well as building gender and age balanced capacity in the
      communities. Overall, the performance of CMDRR committees in Amurai and particularly Abarilela and
      Wera sub-counties was above average. The study recommends that government should adopt this approach
      and replicate it in other disaster-prone areas for effective disaster management.

  • Exploring the Characteristics, Drivers and Control Strategies of Informal
           Settlements on Mkimbizi Hill in Iringa Municipality, Tanzania

    • Authors: Evarist Fundisha
      Pages: 135 - 166
      Abstract: This study explored the characteristics, drivers, and control strategies of informal settlements on Mkimbizi
      Hill in Iringa Municipality, Tanzania. The study employed a mixed research design whereby heads of
      households were randomly selected while key informants were purposively sampled. Data were collected
      through a questionnaire survey with heads of households, in-depth interviews with key informants, and field
      observations. Quantitative data were analysed by statistical product and service solution software.
      Qualitative data were organised into themes and involved content analysis. It was established that the study
      area is occupied by individuals of different social and economic characteristics with informal land tenure,
      limited access to social services, and are exposed to the risk of the collapse of buildings and rockfalls. The
      study also found that informal settlements in the study area were caused by the lack of education on urban
      settlements, proximity to essential social services, cheap plots, and poor settlement planning. Nonetheless, the
      study showed that the strategies used to control informal settlements in the study area included intermittent
      patrol, awareness creation on sustainable urban development, and settlements for economically weak
      individuals. The study recommends proper land use planning for sustainable urban development by the
      authorities.

  • Socio-Economic Background of Households and the implication for Housing
           Choices in Urban Ghana

    • Authors: Simon Boateng, Divine Odame Appiah, Daniel Buor
      Pages: 167 - 202
      Abstract: This study examines the linkages between the socio-economic background of households and their housing
      choices in the urban enclaves of Ghana. Multi-stage sampling technique was used to select 900 participants
      from the study areas. Questionnaire was used to glean data from the participants. Pearson correlation and
      multinomial logistic regression were used to estimate the level of association between socio-economic
      characteristics of households and their housing choices. The study found that the choice of housing type was
      significantly associated with sex (χ2=56.004, p<0.001), education level (χ2=238.895, p<0.001), marital status
      (χ2=28.871, p<0.001), occupation (χ2=202.110, p<0.001), monthly income (χ2=275.682, p<0.001), location
      of household (χ2=46.112, p<0.001) but not household size (χ2=18.642, p=0.42), age (χ2=10.229, p=0.113)
      and religion (χ2=10.361, p=0.110) of the household head. The multinomial logistic regression estimates that
      household heads with no formal education compared to household heads with master degree are .055
      (p<.001) times less likely to live in a detached/semi-detached house compared to compound house. The study
      reiterates the importance of having an informed policy on neighbourhood design and development,
      particularly when designing houses for people of particular socio-economic and cultural backgrounds.

  • Chinese Migration to Ghana: Challenging the Orthodoxy on Characterizing
           Migrants and Reasons for Migration

    • Authors: Joseph Kofi Teye, Leander Kandilige, Mary Setrana, Joseph Yaro
      Pages: 203 - 234
      Abstract: While there is evidence that Chinese migration to Africa has increased in recent years, there is a general paucity of data on the total number of Chinese migrants living in African countries and their socio-demographic characteristics. The reasons for this situation include challenges associated with capturing immigrants in Africa censuses, lack of robust sampling frames to draw representative samples from immigrant populations, high level of irregular migration, and weak migrants tracking systems. Relying on qualitative data and quantitative survey, based on an innovative sampling technique, this paper examines the migration of Chinese migrants to Ghana. The findings challenge simplistic narratives that present the Chinese migrants as a homogenous group. Despite the general perception that Chinese migrants in Ghana are undocumented and lack higher education qualifications, our findings reveal that most Chinese migrants are highly educated persons with legal documentation. While the existing literature focuses on economic push and pull factors of migration to Ghana, the paper demonstrates the importance of social networks, economic potentials and peaceful environment in driving migration to Ghana. Based on these findings, we strongly recommend the need for an informed narrative on Chinese migration to Africa by governments, media, and academics to deal with the misconceptions and generalizations.

  • Community Perceptions on the Ramifications of Mono-use Plastic Shopping
           Bags and Bottles Consumption on the Environment in Morogoro Municipality,
           Tanzania

    • Authors: Mrisho Mbegu Malipula, Theobald Frank Theodory
      Pages: 235 - 264
      Abstract: Tanzania, as it is the case for many countries in the world, is suffering from increased mono-use plastic
      shopping bags and bottles besieged into the environment. This article explores the social perceptions of monouse
      plastic shopping bags and bottles consumptions and the potential that those perceptions offer in mitigating
      the negative environmental impacts associated with their use. The article is a result of a mixed method
      research design that mainly relied on interviews, focus group discussion and household survey with
      Morogoro inhabitants. The fundamental argument of this article is that local communities in Morogoro
      Municipal Council perceive excessive use of mono-use plastic shopping bags and bottles negatively due to
      their dilapidating environmental impacts. As such, they recommend environmentally friendly choices like
      greater use of multi-use plastic shopping bags and bottles to substitute excessive use of mono-use plastic
      shopping bags and bottles for curbing the environmental impacts. Equally, restrictions on usage of mono-use
      plastic shopping bags coupled with voluntary actions aimed at reducing the same were deemed vital for
      sustaining negative effects of said plastic materials in and on the environment.
