Authors: Banjo AA , Tokede AM , Ogunsola AJ , Nosiru MO , Ahmad AO , Oyaniyi T 
Published: March 2021

This study investigated factors determining the willingness to adopt grasscutter domestication technology in South west, Nigeria. Multi-stage sampling procedure was used to select 160 respondents from 9 urban towns in Oyo, Ogun and Osun States. Well-structured questionnaire was used for data collection. Data was analysed using descriptive analysis, correlational analysis and t-test. Results showed that the majority (69.4%) of the respondents were male and married. Coefficient correlation (r value) at (p< 0.05), shows that there is a significant association between respondents’ educational status, religion, household size, primary as well as secondary education with respondents’ willingness to adopt the technology. There was also found significant relationship between, perceived health status of those who are into the grasscutter technology, perceived nutritional value and economic value of the grasscutter domestication technology with the willingness to adopt the grasscutter domestication technology. The result if the T-test revealed that there is significant relationship between perceived ease of practice and willingness to adopt the technology. The majority of the respondents are willing to rear grasscutter if variables like space, fund, availability of ready-made buyer and feed, breeding stock and training are put into place. However, issues relating to having enough plots of land, funding, ready-made buyer of grasscutter, and training facilities are most germane. It is therefore recommended that funding and training on the adoption of the grasscutter domestication technology should be made available to individuals.

Two-Dimensional Electrical Resistivity Investigation of Plants Roots and its Implication in University of Benin Engineering Field, Ugbowo, Edo State, Nigeria
Authors: Avenbuan N , Alile OM , Iduseri OM 
Published: March 2021

The geophysical study of the spread of plant roots have become imperative due to its effect on buildings. Most buildings constructed close to trees; without taking into consideration the extent of root spread, have experienced cracks which sometimes lead to the collapse of such buildings. To investigate the horizontal and vertical spread of plant roots at the University of Benin Engineering field, Edo State, Nigeria, a two-dimensional electrical resistivity imaging was done using the Wenner-Schlumberger array configuration. Data were collected along two profiles; profile 1 was taken along tree paths and profile 2 along grassland area, some distance from profile 1. Profile 1 showed a very resistive top layer underlain by a low resistive layer. The top layer which appeared to be highly resistive was due to the presence of fluid absorbers within that layer. The fluid absorbers are the roots from the trees which are distributed both vertically and horizontally within the layer. With the inversion results, the depths of the roots were estimated to be between 5.00m and 7.50m from the surface; with resistivity values of between 610.00Ωm to 1700 Ωm. The resistivity distribution obtained in profile 2 appears to be more homogeneous than the results obtained from profile 1 with resistivity values of between 320 Ωm to 3500.00 Ωm from the top layer to the bottom layer. The uniformity in the resistivity distribution with depth was due to the absence of tree roots within the formation

Published: March 2021

Investing in trees offer financial and social returns for years to come and it is a lucrative long-term investment in Nigeria. Despite the substantial gain on investment in tree planting, only few people are still involved in the business. This paper analyzed the profitability of investment in tree crop planting for income generation. Benefit Cost Ratio (BCR) and Net Present Value (NPV) were calculated to determine the financial viability of tree crop planting. The study showed that tree crop planting is a profitable business as shown by positive NPV of ₦2,187,822.0 and N2, 782,214.97 for Tectonia grandis and Moringa oleifera plantations respectively, after 10-years of maturation and harvesting at 14 % discount rate with a B/C Ratio of 1.97 and 1.6 respectively. Also, NPV of N1, 575,487.10 for a 5-year small scale private nursery establishment with a B/C Ratio of 2.79 at a 14% discount rate also confirm that the investment on nursery establishment is highly profitable. It is recommended that with adequate support and incentives, farmers can take advantage of these opportunities and invest in nursery enterprise and tree crop sub-sector of the economy

The major concern globally is the need to ensure health, economy, large food production, sustainable management of the environment and the renewable natural resources. Such concern has advance measure part of which generate up to date information necessary for long term exploitation of this resources. But this information itself requires planning as well as machinery for its management in Nigeria. However agro-apiculture/agro-forestry is still nonexistence. This is attributable partly to lack of understanding, information and awareness regarding agro-apiculture practice in forest plantation. And therefore, to create this awareness and draw of authority concerned-Governments, policy maker, town planning and municipal authority to the need for the incorporation of apiculture into agro-forestry for sustainable management. This fact therefore, justifies the growing interest in the apiculture with agro forestry. This paper focuses on the potential role of agro forestry in honey production in federal college of forestry since 1999 to 2016 and its associated environmental problems are highlighted while the potential of agro forestry in honey production are stressed.

Published: March 2021

This study aimed to assess the nutritional and trace elements composition of selected forest fruits sold for human consumption in Port Harcourt. Fruit contamination by heavy metals is an issue of global concern. Nondegradable elements bioaccumulations in tissues and organs have deleterious effects in man. Three (3) Agroforestry fruits species; (Spondias cytherea L. (Anacardiaceae), Syzygium malaccense (L.) Merr. & L. M. Perry Myrtaceae and Cola pachycarpa K. Schum. Malvaceae) were purposefully selected and sourced from three strategically located markets namely; Oil mill, Choba and D/line fruit markets. The fruit species were procured and washed with distilled water and the edible parts extracted, chopped and sun dried properly. The nutritional composition was analyzed using 18th edition of the Association of Official Analytical Chemist while trace metals were analysed using PIXE Accelerator. Spondias cytherea yielded high percentage of crude Protein (8.373±0.1) and Fibre content (11.73±0.03), while Syzygium malaccense was rich in Fat (7.17±0.02) and Ash (4.17±0.04). Moisture content was highest in Cola parchycarpa (12.63±0.05). PIXE Accelerator analysis revealed that the fruits contain high concentration of trace metals; S. malaccense contained Mg (1170±237.0ppm), Si (60.02±68.95ppm), Al (14.89±7.71ppm), Fe (10. 60±4.11ppm), Rb (3.20±0.00ppm) and Ti (1.82±0.00ppm). C. parchycarpa had Zn (6.22±11.80ppm), Cr (1.60±0.75 ppm), Mn (0. 71±0.87ppm) and Cu (0.38±0.33ppm). Ni (0.16 ppm) was found only in S. cytherea fruit. The forest fruits are rich in nutrients vital for healthy growth but the level of heavy metals (Mg, Al. Cr, Fe and Zn) in each of the fruits were above WHO/FAO permissible limit, therefore excessive consumption on a daily/weekly routine should be avoided.

Effect of Landfill Leachate on Groundwater Contamination: A case study of Obio- Akpo Local Government Area, Rivers State, Nigeria
Authors: Golden A.H. , Inichinbia S. 
Published: March 2021

This research investigates the effect of landfill leachate on the groundwater in “Odum”, a community that plays host to a dumpsite along Choba/Alakahia road in Obio/Akpor Local Government Area (L.G.A.) of Rivers State, Nigeria. Five vertical electrical soundings (VES) were conducted using the Schlumberger configuration and also five horizontal profiling were done using the Wenner configuration. The field data were acquired using ABEM tarrameter SAS 300C, and processed using the IP TWO WAY software. The results showed that the area is composed of sandstone, clay, laterite, sandy clay, and sand. Also, from careful analysis and interpretation of the processed data it was observed that contaminated zones have low resistivity (high conductivity). Strikingly, areas of low resistivity such as 11.9 Ωm and others with high resistivity up to greater than 1818 Ωm do exist. The results show that groundwater around this landfill contaminated area contains highly conductive leachates like sulphur, methane, ammonia gas at depths > 16 m. This indicates that the study area is not a good aquifer zone.

Knowledge, Attitude and Practices of E-Waste Workers in Owode-Onirin Scrap Market, Kosofe Local Government Area, Lagos State, Nigeria
Authors: Olowofoyeku A.E. 
Published: March 2021

Electronic devices have become essential to our existence leading to an increase in the rate of electronic waste (E-waste) generation and environmental degradation. This study evaluates the knowledge, attitude and prevailing practices of e-waste workers at the Owode-Orinin scrap market in Kosofe Local Government Area of Lagos Nigeria using 241 Questionnaires to obtain data which were analysed by Pearson correlation coefficient. The knowledge of the respondents was limited to the financial and economic value attached to E-waste meanwhile the environmental and health impact of their occupation were not known, neglected or considered unimportant. A positive relationship was established between education, knowledge and attitude of the respondents. This indicates that increase in education brings about increase in the knowledge and results in positive attitude of the E-waste workers. The strong social tie found to exist among the E-waste workers can be leveraged upon for the transmission of the knowledge about the environmental health impact of their occupation so as to conduct their activities in the safest manner possible.

This study was conducted to identify and characterize bacteria capable of degrading spent oil contaminated soil. The physicochemical parameters of used engine oil were analyzed according to existing standards, while the total heterotrophic plate counts (HBC) and hydrocarbon utilizing bacteria counts were ascertained with the pour plate methods using nutrient agar and minimal salt agar (MSA) media respectively. The results indicated a mean total HBC ranging from 2.86 ± 0.08 to 5.76 log10 CFU/g and mean hydrocarbon utilizing bacterial counts from 1.32 ± 0.09 to 3.82 ± 0.25 log10 CFU/g, with samples enriched with Glycine max (Soybean) recorded to have the highest bacterial counts. The phenotypic identification of the hydrocarbon utilizing bacteria as sources of carbon and energy showed the presence of two primary bacterial genera: Bacillus and Micrococcus.However, from the overall 50 counted colonies, the frequency of occurrence for Bacillus was 41 (82 %) whereas, the Micrococcus was (9) 18%. The obtained data, confirmed the breakdown capacity of autochthonous (indigenous) organisms notably; Bacillus in the reduction of pollutants linked with oil spillage. This provides for reliable and promising approach of ameliorating crude oil pollutants and its inherent threats.

Lithology and Fluid discrimination of Sody field of the Nigerian Delta
Authors: Finecountry S.C.P. , Inichinbia S. 
Published: March 2021

The lithology and fluid discrimination of an onshore Sody field, of the Niger Delta was studied using gamma ray, resistivity and density logs from three wells in the field in order to evaluate the field’s reservoir properties. Two reservoir sands (RES 1 and RES 2) were delineated and identified as hydrocarbon bearing reservoirs. The petrophysical parameters calculated include total porosity, water saturation and volume of shale. The results obtained revealed that the average porosity of the reservoir sands, range from 21% to 39%, which is excellent indicator of a good quality reservoir and probably reflecting well sorted coarse grain sandstone reservoirs with minimal cementation. Water saturation is low in all the reservoirs, ranging from 2% to 32%, indicating that the proportion of void spaces occupied by water is low, and implying high hydrocarbon saturation. The crossplot discriminated the reservoirs lithologies as sand, shaly sand and shale sequences, except well Sody 2 which differentiated its lithologies as sand and shale sequences and distinguished the reservoirs’ litho-fluids into three, namely; gas, oil and brine. These results suggest that the reservoirs sand units of Sody field contain significant accumulations of hydrocarbon.

Forest degradation has become a major concern in many countries around the world as it has become one of the most debilitating land use crisis in tropical ecosystems. Hence, this study assessed the forest degradation indices in Mokwa forest reserve. Data were collected using structured questionnaires and field reconnaissance survey. Five settlements were selected in and around the forest reserve namely Mokwa, Jangi, Epa, Kpataki and Tswanle. Data were analyzed using descriptive and inferential statistics. Results showed that farming (41.7%) was the main occupation of the people, artisan works (18.8%) and studentship had the least (4.2%). Briquetting of charcoal (20.8%) was the highest causes of forest degradation; commercial farming (18.8%), overgrazing (16.7%) and population increase was the least (4.2%).Global warming (22.9%) was the major effect ofdegradation in the study area, soil erosion (20.8%) and the least was low rainfall (9.4%). Agroforestry practices (27.1%) were recorded as the main mitigation measure for reducing degradation in the area. This was followed by Afforestation and enrichment planting (22.9%), tree planting campaign (18.8%) and the least was forest conservation and management (6.3%). The stepwise multiple regression analysis of the causes with other variables showed that briquetting of charcoal had the highest R2 (0.88), followed by commercial farming R2 (0.84), while population increase had the least R2 (0.57). Nevertheless, sustainable empowerment programs are recommended to boost the livelihood of the rural populace and to reduce the overdependence of the people on the forest reserve.

Agroforestry has recently been experiencing a surge in interest as a cost-effective means to enhance food security and well-being. Thus there is a need to assess its contribution of to farmer’s wellbeing. Primary data needed for the study were collected through the administration of questionnaires to agroforestry farmers. Purposive random sampling technique was used to select three forest enclaves in Edo state. A simple random sampling technic was used in the selection of respondents and a total number of 120 copies of questionnaires were administered. Datawere analyzed using descriptive statistics such as frequency counts and percentages and inferential statistics such as Chi-square, Pearson Product Moment correlations (PPMC). The study revealed that the mean age of the farmers in the area was 45.6years. Majorities (85.8 %) were male and 78.3% were married. with 54.2% having household size of between 4 - 6 persons. Majority (84.2%) had formal education. Also, 65.8% engage in agroforestry farming as their primary occupation. The results showed that there was positive and significant relationship between farmers’involvement in agroforestry and their economic wellbeing (χ2 = 76.27, P ≤ 0.001), material wellbeing (χ2 = 93.77, P ≤ 0.001), social wellbeing (χ2 = 73.00, P ≤ 0.001) and psychological wellbeing (χ2 = 132.63, P ≤ 0.001), respectively. It is therefore recommended that farmers should be encouraged to increase their farm holding and also organized themselves into association for them to have access to mechanized equipment

Towards innovative teaching pedagogies in gender research: A review of a gender research methods class
Authors: Olorunfemi Oludayo 
Published: March 2021

This commentary examines the teaching of research methods in Women and Gender Studies in the Gender Studies Unit of the Institute of African Studies, University of Ibadan. It interrogates how the course has increased the awareness of students in the methods of conducting research and how the research they conduct has implications on marginalized populations. The course also highlights the need for a growing body of knowledge that engages the experience of black women in Africa and the African diaspora. The course draws the attention of students to the agency of women through the reading and teaching of various research methods in Gender Studies. An ethnographic approach is adopted using participant observation in the course covering a period of one semester. Also, a critical perspective is applied in discussing the particular epistemological standpoint deployed by the course instructor. In other words, the black feminist epistemology serves as an important strategy for increasing global-minded consciousness of how a course in gender research methods engages the agency of black women using Hip Hop pedagogy.

Attaining the sustainable development goals in Africa: The new CSR for multinational corporations
Authors: Amodu Nojeem 
Published: March 2021

The fact that Africa is one of the worst performing regions in global audits about long-term development trends is longer news. The continent has repeatedly missed targets set by the United Nations and there are concerns it might just be left behind in the attainment of the latest 2030 Agenda Sustainable Development set by world leaders in 2015. With a view to complementing states’ responsibilities towards the provision of public goods and social services useful to actualize the Sustainable Development Goals (SDGs) in Africa, this article interrogates the nature of multinational corporations (MNCs) and juxtaposing the non-state actor responsibilities within wider societal contexts with state duties in advancing the SDGs. The article not only sets the tone for a “new corporate social responsibility” in terms of improved pursuit of sustainability within business communities in corporate Africa, it also recommends workable measures, integrating progressive roles for both the state and MNCs towards the realization of the SDGs on the continent.

“Humanizing” investments in the extractive industries in Africa through the IFC’s sustainability policies
Authors: Okoloise Chairman 
Published: March 2021

International financial institutions face enormous challenges in Emerging Markets and Developing Economies (EMDEs). They finance infrastructure projects, manage vast investment portfolios, offer advisory services, and contribute to economic development in EMDEs. In the process, they areexposed to huge risks and face reputational damage if they act recklessly or have little or no regard for their projects’ adverse impacts on thirdparties. In the context of natural resource exploitation in Africa, the weak governance of environmental and social risks often results in devastating consequences for communities proximate to investment projects. Promises of infrastructure and social services, job opportunities and economic boom have only often delivered land grabs, forced displacement, cultural infringements, environmental pollution, conflicts, health disasters, misery and sometimes deaths. As calls for greater corporate scrutiny increase, investment project facilitators in the extractive industries like the International Finance Corporation (IFC) must respond appropriately. To preserve its reputation and long-term market access, the IFC needs to apply a higher degree of due diligence and sustainable business conduct that proactively treat risks and limit its exposure. With the rising number of complaints against IFC policy compliance, including projects tainted by scandals and the debarment of companies from accessing international finance, this article demonstrates that merely promoting sustainable investment policies on paper is inadequate. Using a human rights-centred approach to development project financing, the article critically assesses the extent to which the implementation of the IFC’s sustainability framework can practicably protect resource-rich communities, safeguard human rights and ensure sustainable development outcomes in Africa.
