3D Printing Technology – Applications, Benefits and areas of opportunity in Nigeria
(IJAAR, 2017-03) Oluwole, Raji, Ibrahim
Three-dimensional (3D) printing technology, often referred to as additive manufacturing differs from traditional manufacturing processes in that 3D objects are built by successively creating layers of material on top of each other. Since development in 1980s, 3D printing has undergone technological transformation that could fundamentally alter production processes in a wide set of applicable areas. Despite the accelerated advancement, both in academic research and industrial application that 3D printing technology has witnessed in diverse areas of human endeavor especially in advanced countries; the technology is relatively at its infant stage in developing countries like Nigeria. Thus, this work attempts to address the underrepresentation of research that is specifically concerned with the impacts that 3D printing can make in diverse sectors in developing countries like Nigeria. It addresses this issue by focusing its investigations on the applications of the technology, derivable benefits from the application of the technology as well as diverse areas where 3D printing can present a great deal of opportunities for Nigeria.
Analysis of Stakeholder’s Perspectives towards Conservation of National Park, Northern Province, Rwanda
(IJIRSET, 2017-09) Nsengumuremyi, Concorde; Mbatudde, Maria; Imanishimwe, Ange
The management and sustainable use of Protected Areas Management Policy in Rwanda is of great interest to many stakeholders. This study was conducted from May to August, 2016 to find out local communities and other stakeholders perceptions towards co-management of Volcanoes National Park of Rwanda (VNP). The sample size of the study was 81 respondents including neighbouring rural community from two sectors that depend on using the VNP usually illegally and the key respondents from institutions and local leaders whose resources assist the VNP management. The findings indicated that stakeholders have different perspectives on co-management activities of VNP. Some of interviewed farmers especially those bordering VNP in Kinigi and Shingiro sectors of Musanze District showed negative attitude where they are not willing to perform agriculture on their lands because of crop destruction by wild animals from the park. Both the level of synergy and approaches used were moderate by scale used as indicated by the study findings. The study findings indicated that there is no relationship between stakeholder’s perspectives and co-management of VNP (r=0.145, P>0.05). It was noted that stakeholders express various challenges such as lack of enough alternative solutions to the problems met by rural community and low level of participation in decision making. There is a need to find ways in which local leaders could be taken on a tour of operational and Park-people policy guidelines need to be formulated that will define roles of local stakeholders in protected area activities and programs.
Assessment of Effect of Rice Hush Ash on Burnt Properties of Badeggi Clay.
(IJAR, 2017-05) Peter, O.; Abolarin, M. S.; Anafi, F. O.
The effect of Rice Husk Ash (RHA) on the burnt property of clay (Badeggi) in Gbako Local Government Area of Niger Sate, Nigeria has been evaluated. 0% to 15% weight proportion of Rice Husk Ash (RHA) blended with clay were prepared for the the basis of this analyses. X-ray diffractometer (XRD) and X-ray florescence spectrometer (XRF) were used to determine the mineralogical and chemical constituent of the clay and RHA respectively. Plasticity of the clay, apparent porosity, bulk density, linear shrinkage, thermal shock resistivity, compressive strength, hardness, refractoriness and resistance to chemical attacks of the clay, and clay - RHA blends were analysed. The XRD analysis indicated that the clay was mainly Albite, with sufficient amount of Illite minerals. Result of chemical analysis indicated silica (SiO2) 53.50% and alumina (Al2O3) 28.70% to be main constituents of the clay. SiO2 content in the RHA was highest at 89.72% while other oxides were found in traces. Physical and mechanical property test confirmed that the inclusion of RHA in the clay resulted to considerable improvement in some properties and is beneficial for ceramic ware production.
Assessments of the Forest, Poverty and Environmental Security Nexus in Uganda
(IJSES, 2017) Akiyode, Oluwole O.; Nwankwo, Levi I.; Iyalomhe, Felix O.; Abdu, Yusuf A.; Tumushabe, Anne; Omuna, Daniel
The environmental security and quality of every society are important in the determination of human development and socio-economic developments and its level of peace. The potential of environmental security of a location depends on the sustainable management of its forest. This is because of the ecological services being rendered by forest to the environment. Thereby, the societal system will need to encourage forest sustainability and security in order to continue to enjoy its ecological services. Forest utilization and poverty are interlinked, since the level of poverty may contribute to the rate of utilization of forest while the rate of utilization of forest contributes largely to environmental security and quality. The study examines the relationship between the level of poverty to the use of forest and its implication on environmental security using Uganda as a case. There has been a continuous reduction in the size of Uganda’s Forest Area (Percentage (%) of Land Area) since 1999. The study interconnects the continuous reduction of the Forest Area (Percentage (%) of Land Area) to the country’s well-being and livelihoods and suggests its implications on the environmental security and quality. The study advocates sustainable approaches to the management of forest.
Can Governance in Revenue Sharing Be a Pathway for a Win-win Situation between People’s Livelihood Improvement and Conservation?
(Council for Innovative Research, 2015-05) Twinamatsiko, Medard
This paper establishes the importance of good governance in improving local livelihoods and support for conservation. The study uses empirical realities from Bwindi Impenetrable National Park, an afromontane Gorilla sanctuary that was recognized by UNESCO in 2005 as a world heritage due to its rich biodiversity. Governance is an important procedural dimension of equity that entails decision making processes and how local people are involved in matters that most affect them. The paper uses a Policy Arrangements Approach to illustrate the procedural dimension of the Justice and Equity Framework. A mixed method approach was used to generate results in this paper. Household surveys, key informant interviews and Focus Group Discussions were employed for data collection. Linear and Multi Logistic Regressions were used to determine the level of significance and relationships that exist between governance, people‘s livelihoods and conservation support. Polychoric Principal Component Analysis (PCA) was used to generate indices of livelihood improvement and conservation support. Results revealed that meaningful involvement, leadership composition on committees, local capacity, information flow and awareness and accountability significantly influence people‘s livelihoods and conservation of Bwindi. Local people are not only concerned about distributive equity in benefit sharing but also the procedural dimension. This entails being part of revenue sharing projects from the design phase to the evaluation phase. The study recommends the use of equity framework in revenue sharing in order to increase greater involvement of local people in decision making processes.

Design and Implementation of an Electrostatic Precipitator and Its Cleaning System for Small Scale Combustion
(IIJSR, 2017-12) Adabara, Ibrahim; Hassan, Abdurrahman S; Hassan, Abdurrashid S
A simple wire-plate electrostatic precipitator (ESP) was constructed in order to test the efficiency of collecting smoke particles from combustion of rubber-wood that is used as a source of biomass energy. The ESP contains collection cylinder electrode and 2 wire electrodes between cylinder. The maximum input voltage of the Wheatstone bridge circuit using a high-voltage neon transformer was 10.5 kV (DC). The gap between the cylinder and the distance between wires were adjustable. Results from the field test in a furnace indicate that the device could be used for a period of about one hour before cleaning the electrodes was required. The collection efficiency was decreased during the course of wood burning as the dust loading increased. Maximum efficiency was near 80% during the initial period. The distance between the collection plate electrodes had a greater influence on efficiency than the distance between the wire electrodes. The cleaning system used in this experiment was made from a row of PVC pipes to allow water to discharge radially to the cylinder electrodes on both sides. Efficiency was increased after 120. This ESP is suitable for small and medium-sized enterprises (SMEs) to alleviate the release of detrimental chemicals such as PAHs into the atmosphere.
Effect of Community Hygiene and Water Handling Practices on Drinking Water Quality in Mpondwe Lhubiriha Town Council, Western Uganda
(Kampala International University, 2023-10-17) Wilfred, Mumbere
Water safety and quality are fundamental to human development and well-being. The aim of this study was to determine the effect of community hygiene and water handling practices on drinking water quality in Mpondwe Lhubiriha Town Council, Kasese District, Western Uganda. Sixteen samples from different water sources and storage vessels in households were analyzed for physicochemical and microbiological Quality during wet and dry season as described in UNBS Portable water quality analysis guidelines. Characterization of Community hygiene, household drinking water handling practices and risk of water contamination was determined by Qualitative methodology. The study findings revealed that community hygiene and water handling practices had a direct effect on water quality where 97.70% of respondents do not practice household water treatment methods. PH, E.C, TDS, temperature, and total hardness were within permissible limits of WHO standard while there was a variation in Dissolved oxygen and nitrates values. Microbial analysis results showed a variation in Total coli and Escherichia coli above UNBS standard this could be due to cross contamination, poor water handling practices where some respondents (41%) had no specific cleaning schedule for water vessels, most respondents (54.00%) were using same vessels for water collection and storage as well as factors from already determined household sanitary risk factor of 39.00-90.00% while Salmonella spp. and Enterococcus bacteria was within limits of WHO standard. This research also revealed that Total coliform and E. coli have a strong positive correlation with Nitrate presence in the water samples (r=0.412, p=0.008) and Nitrates (r=0.557, p=0.000) respectively. Water from some sources and households in this Town Council is not safe for drinking and domestic use. Therefore, should promote good community hygiene, water handling practices and appropriate household water treatment practices to prevent Drinking water Quality variations from the set WHO standard.
Effect of Land Pollution on Community Sustainability in Nakawa Division, Kampala, Uganda
(Kampala International University, 2023-11) Hussein, Hamza Abdisalam
The was study to assess the effects of land pollution on community sustainability conducted in Nakawa Division, Kampala, Uganda to establish the causes of land pollution among the communities, determine the effect of land pollution on community sustainability, and to design mechanisms that can be employed to reduce land pollution and ensuring community sustainability. The data was collected from 182 respondents and 7 key informants. The study results indicated that, industrialization, institutional factors, limited institutional capacity to plant vegetation, low effectiveness in monitoring by NEMA, ineffective implementation of policy, environmental and socio-cultural systems were major causes of land pollution. The effect was generally more negative hence the assertion that land pollution is a key towards community sustainability. It was established that land pollution reduce bio-diversity, increased dangerous gases and generally the community health in terms of plants, animal and people health in the communities. Also, about 80.2% of the respondents said that there were no mechanisms for reduction of land pollution and enhancing community sustainability. The study concludes that the occurrence of land pollution has generally reduced the community sustainability therefore, there is need for industrialization to be effectively managed to incorporate the environmental controls, effective policy implementations, monitoring of land polluters and provision of general environmental controls.
Effect of storage conditions on the methanol content of burukutu produced from different sorghum varieties; a response surface methodology approach
(American Association for Science and Technology(AASCIT), 2018-06-01) Somtochukwu, Igwe Victory; Chinenyenwa, Omeire Gloria; Awuchi, Chinaza Godswill; Kwari, Mercy Ibrahim; Oledimma, Ngozi Uchenna; Otuosorochi, Amagwula Ikechukwu
Methanol content of burukutu made from different sorghum varieties was studied using Response Surface Methodology. A three-level three-factorial Box-Behnken experimental design was adopted to study the effects of storage conditions and chemical properties on burukutu produced from different sorghum varieties. The methanol content was determined and results obtained were analyzed statistically using the response surface approach. Results showed a significant difference (p<0.05) on the effects of storage time, storage temperature and their interactions on the physicochemical parameters (methanol, pH) of burukutu. There was no significant difference (p>0.05) due to different sorghum varieties. Increase in storage time showed a significant decrease in pH (6.21-2.88). The R2 obtained from the statistical analysis of burukutu were all higher than 0.75 (75%) which depicts that the model used adequately fits the relationship between the variables under consideration. Exposure to high concentration of methanol has numerous health consequences.
Effects of repeated deep frying on refractive index and peroxide value of selected vegetable oils
(IJAR, 2018-04) Godswill, Awuchi Chinaza; Amagwula, Ikechukwu O.; Igwe, Victory S.; Gonzaga, Allan Isiaga
The peroxide values and refractive indices of palm olein, sesame oil and sunflower oil were evaluated before deep frying. The vegetable oils were used to frying white Irish potato chips in three batches, with the peroxide value and the refractive indices of the oils determined after every stage of deep frying. Results of the study show that both refractive index and peroxide value of the vegetable oils largely vary with deep frying. The findings show that refractive index and peroxide value of sesame palm and sunflower do increase on frying, though not in a linear fashion. The refractive index of palm oil increased from 1.4653 to 1.4655 after frying the three consecutive batches; the RI of sunflower oil increased from 1.4722 to 1.4724 respectively. There was no significant change in the refractive index of sesame oil. The peroxide values of palm oil increased from 1.9948mEq/kg to 9.3020mEq/kg after three consecutive deep frying. The value of peroxide of sunflower oil raised from 10.6359 mEq/kg to 19.3101 mEq/kg while that of sesame increased from the initial 3.9914 mEq/kg to 11.9555 mEq/kg on frying the second batch and finally reduced to 11.3095 mEq/kg after frying the third batch of Irish potato chips. Tables 3 and 4 show the relationship between refractive index and peroxide value of the vegetable oil. These findings indicate that repeated deep frying leads to corresponding rancidity and spontaneous deterioration of the vegetable oil.
Environmental health determination and assessment of physico-chemical characteristics in Oloshi River, Nigeria
(FTST, 2017) Opara, Jacinta A.; Okwodu, Nicholas E.
The Physico-chemical characteristics of the surface waters and sediment in Oloshi River, non-tidal fresh water were studied between July and December 2015. The Oloshi River drains and receives effluents from cassava mill treatment (starch mill) factory and oil companies in the area. The inhabitants are predominantly farmers and fishermen. All parameters were analyzed using standard methods for examination of water and waste water (ALPHA 1998). The results of water and sediment physico-chemical parameter lies between a mean range of 4.2- 4.4 for pH, 28.5°C for temperature, 1.4-4.8 NTU for conductivity, 1.4 – 4.9 NTU for turbidity, 3.9 – 4.4 ppm for Po4, 0.2 – 1.2 for No3, BOD= 1.1 ppm. The results showed low physico-chemical levels which do not pose serious health risk except for phosphate levels with a range of 3.89 to 4.4 ppm. With regard to seasonal variation, dry season recorded higher values than rainy season except for pH and No3 of the sediment parameter in which the rainy season recorded higher than dry season. Increased level of pollutants in the Oloshi River may have significant effect on the ecological balance of the River.
Environmental health, ecological diseases and sustainable development of fish culture in Nigeria
(International Journal of Biology Research, 2017-10) Opara, JA; Okwodu, NE; Abere, SA
Although existing fisheries management systems have largely failed, the public and most scientists believe this failure is due to overfishing and that the solution includes the precautionary approach, marine protected areas and ecosystem management. The solutions commonly identified actually treat a symptom rather than the problem. Solutions do exist and have the common characteristics of changing the incentives to make what is good for an individuals or group good for society. Example already in place is the aqua-cultural development which has unveiled to an extent the degree to which fish farm can sustain the economy and provide the necessary protein need of the country. Fish farmer’s sees their business as an answer to the ecological problems associated with over fishing in the wild state and other human impact on rivers. Ecological disease of fish culture caused by poor water quality has posed a serious threat to fishing industry in Nigeria. These stress factors in the environment has been magnified to catastrophic levels in recent times because of the rate of environmental degradation that has been going on unabated. Addressing ecological diseases of fish culture constitute one of the most important steps towards improvement and increasing productivity of fish culture establishment in Nigeria. It is apparent that ecological diseases of fish develop from human anthropogenic impacts on water quality and poor management of the system. Fish farmers can keep their fish in good physical condition and improve productivity by proper design of facilities, good management and good care.
The Impact of Climate Change on Community Livelihood in Jowhar Middleshabelle Region of SomaliCommunity Participation in Environmental Conservation Practice In Guri’el, Galmudug State, Somalia
(Kampala International University, 2023-09-24) Ali, Mohamed Yusuf
This study established the contribution of community participation in environmental conservation practice, examined the challenges faced by the communities in environmental conservation practice, and also proposed mechanisms that can be employed in environmental conservation practice in Guirel District. The study adopted a quantitative research method in which questionnaires were used to gather data from 171 respondents, with the use of descriptive statistical analysis to answer the research questions. The research hypothesis was tested at a 0.005 alpha level of significance. The study established that environmental conservation in the district is done through several mechanisms including the provision of seedlings to the community by the Government, periodic tree planting, provision of land for tree planting, the establishment of tree schemes by the Government, and provision of seedlings for reforestation by NGOs. Therefore, communities play a big role in the implementation of conservation programs in the district through the actual planting of trees and monitoring of the conservation programs. However, involved communities were challenged with a lack of financial support, limited information on conservation, lack of accessibility to the reforestation schemes, and a low level of awareness and this limited their support of the programs. The study therefore, recommends that a forest management plan that is involving community members in every stage and also making them play a key role in the management of the forest should be made so that they would argue what they want and how they want it done for a better understanding of the forest management. The study recommends that there is a need for government to popularize unknown species so that communities can benefit from their commercial exploitation.
Impacts of climate change on crop production. A case study of Tisai Island, Ongino Sub County, Kumi District
(School of Engineering and Applied Sciences, 2015-07) Akurut, Marion
Climate change in Tisai Island is one of the constraints on crop production and has become so rapid especially in the last 10 to 20 years. According to this study, climate change refers to the average weather or statistical description of the mean and variability of relevant quantities over a period of time ranging from months to thousands of millions of years (30 years). The main objective of the study was to explore the impacts of climate change on crop productivity in Tisai Island and the specific objectives were; to find out the causes of climate change, to establish the effects of climate change on crop productivity, to identify the measures used in mitigating climate change effects on crop productivity, and to examine the measures used in increasing crop productivity amidst climate change. The sampling methods were random sampling and judgmental sampling and the sample size was 50 respondents. The instruments for data collection were; questionnaires, interview guides and observation which helped in identifying different climate change phenomenon. During the study, the researcher found out that climate change in Tisai Island is caused by many factors like charcoal burning, bush burning, fossil fuel combustion and deforestation. This has led to various effects such as unreliable rainfall, extreme temperatures, increased pests and disease, floods and soil infertility. However, some mitigation measures are being implemented by the government and nongovernmental organizations to curb down the situation and they are; strict laws and policies, public awareness and participation, afforestation and reforestation and public participation. In conclusion, climate change in Tisai Island is caused majorly by deforestation and bush burning and to a small extent caused by fossil fuel combustion resulting to high temperatures, floods, droughts and unreliable rainfall. However these have been mitigated by measures like awareness creation, public participation, laws and policies, afforestation and reafforestati on. The researcher therefore recommends that development projects like rural electrification programmes, modern agricultural programmes should be extended in the area to help in regulating human activities Iike de forestation, bush burning and charcoal burning. The National Environmental Management Authority (NEMA) together with the government and other organizations should carry out various projects like afforestation and reafforestation and irrigation. Fines and charges should put in place to combat environmental degradation. Public awareness should be increased through adverts on radios, posters and carrying out freely attended seminars and also Farmers should also be provided with fast maturing crop varieties to increase their yields. Lastly promotion of Food security by encouraging people to store food for their families in the granaries
The Impetuses and Hurdles of Renewable Energy Applications and Development in Montserrat
(2019-11-11) UZORKA, AFAM; MAKERI, YAKUBU AJIJI; ODEBIYI, SAMUEL OLUWASEGUN
The economy of Montserrat was severely disrupted by volcanic activity which began in July 1995. Prior to this date, Montserrat is an open and dependent micro-economy with limited economic activity which is the biggest threat to sustainable energy development. Above all, Montserrat dependency on the fossil fuel is the biggest obstacle for the long term economic growth. The combination of these challenges gives impetus for Montserrat to diversify its economy via a green economy that will pave a way for the long term economic stability while addressing environmental and social concerns in the country. Montserrat has adapted long-term plans for a transition to green economy. A major strategy is to replace fossil fuels with renewable energy (RE) sources as the fundamental energy source. Montserrat has substantial RE resources for the provision of energy services and production, yet these resources remain untapped. It is therefore crucial that the use of these abundant resources should be heightened. This paper examines and discusses the potential and current RE utilization and development in Montserrat from the perspective of sustainable development. The status of the different RE resources and their application/utilization, including details of existing projects in the country, are carefully explored and discussed. The possible impetuses for a huge advancement of RE applications and development in Montserrat are also discussed before explaining the major hurdles and challenges faced by the energy sector as regards RE. Measures and policies required to facilitate the utilization of RE in Montserrat are proposed. These evidence-based policies could guide the delivery of affordable and sustainable energy solutions for all by 2030 in Montserrat
The implications of sustainable development programmes on environmental sustainability in Nigeria
(IJAR, 2017-02) Akiyode, Oluwole Olusegun; Wilson-Osigwe, Menwo Ukechi; Oluwole, Raji Ibrahim
Human security and sustainable development all over the world hinges on successful environmental sustainability. Nigeria was a signatory to Agenda 21 in 1992 and has been introducing policies in its systems which include laws that serve the three tier governments (Federal, States and Local Governments) in its bid to achieve environmental sustainability. These laws and policies serves as instruments for environmental protection, planning, prevention and pollution control. This study analyses the state of Nigeria environment before the inception of the Millennium Development Goal MDG 7 which was to ensure environmental sustainability and examines what happens after the programmes took off and ended. It examines sustainable practices in Nigeria that supports and encourages environmental sustainability. It identifies challenges to the achievement of environmental sustainability in the MDG 7 programmes. It also classifies the emerging environmental issues in the country. At the end, it advocates forward strategies in the achievement of environmental security in Nigeria.
Industrial waste management: brief survey and advice to cottage, small and medium scale industries in Uganda
(International Journal of Advanced Academic Research | Sciences, Technology & Engineering, 2017-01) Godswill, Awuchi Chinaza
Cottage, small and medium scale industries in developing countries account for large share of employment and, in most cases, production. Recent growth of these classes of industries has been in response to high labour availability and low financial resources in most of these developing countries. However, the urban management program of UNCHS (Habitat), together with World Bank, UNDP, and other collaborating agencies, have pointed out the general lack of technical-know-how and adequate knowledge on waste management regarding the cottage, small and medium scale industries and their relative impact on the environment. The definition of micro (cottage), small and medium enterprises includes all types of enterprises irrespective of their legal form (such as family enterprises, sole proprietorships or cooperatives) or whether they are formal or informal enterprises to ensure inclusiveness (MTIC, 2015). A cottage industry has within 1 to 4 employees, small scale 6 to 50, medium scale 50 to 300, and large scale >300 employees.
Inquiry-Based Learning and Environmental Education in Nigeria: An Analysis of Students’ Acquisition of Manipulative Skills in Geometric Construction
(SCHOLARS WORLD, 2017) Opara, Jacinta A.; Nguuma, Jimin
This paper perceives geometric construction as an important aspect of environment education. It examined the effect of IBL on students’ acquisition of manipulative skills in geometric construction in education zone B of Benue State, Nigeria. The study also investigated whether the skills acquisition could be affected by gender and ability levels. Sample for the study comprised of 300 Senior Secondary 1 students selected from six schools within Education Zone B of Benue State using a multi-stage sampling technique. The study adopted a quasi-experimental non equivalent pretest-posttest design. Intact classes were assigned to the experimental and control groups. Data was generated using Geometric Construction Manipulative Skills Test (GCMST) which was the research made essay test. The reliability of the instrument was computed using Pearson’s Product Moment Correlation Coefficient and found to be 0.98. The study was guided by three research questions and three hypotheses. Data collected were analysed using descriptive statistics of mean and standard deviation to answer the three research questions and inferential statistics of Analysis of Covariance was used to test the three hypotheses. Hypotheses tested reveals that students exposed to IBL exhibited greater manipulative skills in geometric construction (F=392.69; p=0.002) than those exposed to conventional methods. In addition, male and female students taught using IBL did not differ significantly in acquisition of manipulative skills (F=1.58; p=0.211). Also, High and low ability students did not differ significantly in demonstration of geometric construction skills acquired (F=0.14; p=709). Based on these findings, the study recommended among others that mathematics teachers should use IBL in teaching students practical mathematics skills. It concluded that IBL is a framework for outcome-based education which is a trust towards greater learner-centred pedagogy therefore it should be considered a useful addition to the variety of existing mathematics teaching approaches that attempts to involve learners more in their own learning.
