Abstract

The study focuses on the sociological insight on the computer based test (CBT) and the reintroduction of pen to paper examination in University of Maiduguri. The objectives of the study were to examine the importance of CBT and pen on paper examination in University of Maiduguri, identify and compare the difference in student performance between the Computer Based Test (CBT) and the pen on paper examination in University of Maiduguri, to find out the challenges of CBT and pen on paper examination in University of Maiduguri. The study adopted Behavioural Learning theory as the theoretical framework for analysis. The data were obtained from primary and secondary source. The primary source was derived from the questionnaire, while the secondary data were incurred from the reviewed of relevant literature. Purposive sampling techniques were adopted. The study used 400 questionnaires in data collection, but only 392 were returned and found fit for the analysis However, Four (4) Faculties were randomly selected and in each Faculty, four (4) Departments were selected each. The findings also revealed that majority of the respondents agreed that pen on paper examination is often more practical which seems like the best way to express themselves than the computer based test (CBT), and that pen on paper examination produce graduates that can defend their field of study. It also reveal that pen on paper examination motivates student to read more widely and understand the context more easily than the Computer based test (CBT). It is recommended that the University management should create a trusted committee for the collection of the answer sheets after the submission from each student in the examination hall. By doing this, the problem of missing scripts will be solved. The pen on paper examination provides favourable conditions for cheating during the examination. Thus, it is recommended that the University management should provide CCTVs in examination halls for monitoring, and allowing students to use only items that the school management provided, and be cautious about the students leaving the examination hall and limit student’s ability to change answer sheets during the examination period. Student’s performance is low in pen on paper examination unlike the computer based test (CBT). Therefore, the examiners should provide direct questions instead of applied question which may confuse the students, and at the end it might affect the student performance.

Abstract

This research examined the impact of exposure to foreign mass media content on dress culture among students of University of Maiduguri. The study aimed to determine the level of consumption of foreign mass media contents among the students. The Cultural Imperialism theoretical perspective was adopted to explain the data. Using a quantitative survey research approach and purposive sampling technique, a sample of 200 respondents was drawn from the population of 37,943 undergraduate students of the university. The study suggests the existence of a high levels of the students’ exposure to foreign movie contents. Therefore, this study concludes that students’ exposure to foreign media content could have an impact on their dress patterns on campus. Hence, the study recommends that a course on Nigerian movie industry (e.g., Kannywood and Nollywood) focusing on the use of Nigerian local attire should be introduced into advanced level educational curriculums, the University management should include African dress patterns in the syllabus for the General Studies.

Abstract

The level of marginalization is noted in the distribution index between developed and undeveloped nation. This margin is a clear indication why some countries are richer than others. In other to address these problems, research purpose is formulated which aims to analyze the of effect global market space on Nigerian economic. Quantitative research methodology was used. Data source from CBN statistical bulletin for 2002 – 2018 was used for the analysis. Using unit root test, it shows that foreign direct inflow, total import, total trade and balance of trade are stationary at 1st and 2nd different level of differencing, while the levels of the differencing show that Gross Domestic Product and total export are non-stationary after second differencing. The results of regression analysis when economic developmentproxy as Gross Domestic Product (Dependent Variable) and foreign direct investment inflow, total import, balance of trade, total trade and total export proxy as globalization (independent variables) shows that all the independent variables are positively and significantly related to Gross Domestic Product except total export which was found to be negatively related to Gross Domestic Product. Base on these findings the study recommended that the government should implement strong macroeconomic and structural policies required to gain confidence of foreign investors so as to boost the country’s productivity, growth and competitiveness.

Abstract

Tourism has become a major income earner for many countries Worldwide having a contribution of about 11% of the world’s GDP. Its contribution to trade and businesses and creation of employment is attested to by many authorities. However it is faced with some challenges which hamper its progress and maximum utilization of the enormous potentials. Among these challenges is the near absence of the information about tourism potentials of Nigeria and indeed Kogi state in distant nations and countries. When tourist eventually arrive the country, they are faced with problems of how to locate their choice destinations and how to interact with the locals. Any system that can provide the needed information about tourism destinations to potential tourist in their distant countries to enable them plan their visit and itinerary in a convenient and easy fashion would immensely reduce their rigour and enhance their zeal for visit. The procedure adopted was the integration of remote sensing, GPS and multimedia GIS and customization of Google map via Google my map Application. The multimedia data was used to correct the limitations of Google map as navigation tool to enhance its applicability. The cyber link power 2 Go8 was used in converting sound to wave files. While cyber link Photo Director 5 converted photographs and textual information to video clips. ULEAD was used in transferring multimedia elements from the digital camera into the PC. Other software used included the Movavi video suite used for fixing playtime of video and audio as well as converting the audio from 3gpp to MP4, the tunestotube software converted the sound and text into compatible format for the system before finally being moved into the YouTube channel. All the multimedia elements were hyperlinked onto the Google map from the YouTube. The database therefore resides in the YouTube. The map generated is highly responsive and to every query raised, it gave corresponding answer.

Abstract

Human trafficking have become a worldwide industry, incorporating millions of people annually and generating an annual turnover of billions, besides drugs and gun running which negatively affect our socio economic development. Besides women and children, Nigeria is a country of origin, transit and destination for human trafficking: the main objectives of the study was to assess the effect of human trafficking on socio economic development in northwest Nigeria, despite the effort of government to curb the menaces of human trafficking through Immigration, NAPTIP, police and NDLEA, but yet the numbers of incidences are increasing imperfectly, the research methodology  was exploratory based on content analysis, secondary data were also utilized for the study. The study revealed that data generated from the irregular migration section of Kano state indicated that on 13th/04/2019 nine suspected victims of migrant smuggling were arrested by joint operations with NAPTIP and the case has been transferred to NAPTIP, More so, the study found that there was inadequate funding to match the responsibilities of human trafficking and rehabilitation of the victims. Therefore, the study indicated that there was low motive behind public enlightenment and awareness through seminars, workshops and television programs as well as other means aimed at educating the public on the effect of human trafficking on socio economic development, also research shows that there was inadequate security personnel particularly immigration (border patrol/border guard) that would curtail the menace of human trafficking. The study recommended that government should create public enlightenment and awareness through seminars, workshops, radio and television programme as well as other means with aimed to educate the public on the effect of human trafficking, it was recommended that the government should put more effort to address the root cause of poverty and unemployment to our teaming youth in order to reduce the incidence of human trafficking. However, it also recommended that government should provide enough fund on budgetary allocation to the responsibilities of fighting human trafficking and rehabilitation of the victims as well as adequate provision of security.

Abstract

Until recently, speech was a rare means of communication between man and machine due to low level of technology. Similar pronunciation patterns among same ethnic groups could be explored in the local development of speech technology products in Nigeria because Speech-to-Text (STT) systems are dependent on the set of data used to train them. This is experienced in most STT-enabled devices (like the mobile phones, automobiles, television) when they are used by persons outside the group of data they are trained with and the performance of such devices deteriorate. This paper presents an STT algorithm that is robust to the accent of Nigerian English speakers. In the data acquisition stage of the work, about a total of 27,000 isolated speech data were collected from five ethnic groups; 30% were Yoruba speakers, 29% were Hausa speakers, 20% were from Igbo speakers and the rest 21% were from Fulani and Ijaw speakers. The data were pre-processed, after which the features were extracted using the Mel-Frequency Cepstral Coefficients (MFCCs) with 13 coefficients. The recognition technique adopted was the Hidden Markov Model (HMM) with varying number of states. The results of this work reveal that for the 10-word vocabulary isolated speech considered with the number of state = 5 an average accuracy of 86% was achieved. An 86% average accuracy was also achieved with the 10-word vocabulary and the number of HMM state =7. For the 10-word vocabulary with number of state = 9, an average accuracy of 90% was achieved.

Abstract

COVID 19 Corona virus pandemic disease has brought about the challenge of using Information and Communication Technology (ICT) based virtual Technology in teaching and learning systems. The use of ICT in education is nothing new, but the question is where the limit is when the use of ICT does not have the desired effect, classroom delivery with the use of modern technology is still very low in Nigeria. From the report of World Health Organization (WHO) and World Bank (2011), physically challenged persons carry a significant proportion of the world’s population, about 15%, as a result of differences in educational standard to the normal individuals, they are rarely seen as contributor to productive human capital development of the Society. Most of the Learning Challenged children access to education, this is as a result of several challenges they face in learning and comprehension. Most schools curricula were developed without considering the fact that, different categories of students including people living with learning challenges will also make use of them. This was never put into consideration during the requirement specification of those curriculum. This paper focuses on the use of ICT based virtual assistive Technology to teach  early childhood education children with learning challenges most especially during this COVID 19 pandemic challenges. This will enhance the learning ability of this category of Students and also motivate their desire to learn. This research work was carried in one of the government school for handicap children in Nigeria. From the learning ability testing of the research, it was discovered that the students learn faster and easier with the use of ICT base assistive technology than normal classroom learning. As a result of this, this paper focus on comparing level of efficiency of the ICT base virtual reality assistive technology over normal classroom learning for these categories of Students.

Abstract

Relevant influences have led to radical changes in terms of teaching and learning approaches approved in the field of education. Nowadays, the students have quite different attitudes when compared to the past, and their expectations have been shaped accordingly. Therefore, it is quite difficult to draw interest and curiosity of the students today to learning activities through the traditional teaching approaches. Moreover, it is not easy to overcome some problems regarding teaching and learning by obsolete approaches. In this regard, the educators today show highly much interest in the innovative teaching methods that solve the needs of this age. One of those approaches is flipped classroom model. It is believed that flipped learning has gained great attention of many researchers as a result of what educators are implementing at their classrooms. This paper analyzes the concept of blended learning and its didactic possibilities to make an effective transition from a traditional learning model to an integrated model couple with electronic environments and resources being widely used.

Abstract

Sustainability is the solution to combating the negative environmental impacts in our environment. In Nigeria the practice of sustainability via green architecture in our built environment is a necessity in fighting the environmental concerns of the Nation. This is because green Architecture remains the foundation of sustainable construction, it refers to a structure that is resource-efficient in terms of economy, utility, durability, and comfort. Nigeria has all the necessary potential to support the implementation and practice of green architecture concepts, however, this practice is very scarce and discouraged by problems like huge power, water, & processed material consumptions due to increased urbanization, and limits of the knowledge of the Professionals in the construction industry. Literature review is used in this study to appraise sustainability and green architecture existence in Nigeria so as to identify the obstructions to its practice. The study was able to identify the impediments to the practice of green buildings in Nigeria and concluded that the sustainable environment will continue to be an illusion if the construction industry and other stake holders fail to overcome these categorized impediments.

Abstract

This study was carried out in agreenhouse in order to determine effects of different irrigation levels on lettuce yield, grown from October to December 2019, in Federal College of Forestry, Jos, Plateau State, Nigeria. Different irrigation water amounts based on Class-A-Pan evaporation were applied to the plants by drip irrigation system at four irrigation levels (120%CWR= 1.2, 100%CWR=1.0, 80%CWR=0.80, 60%CWR=0.6) in one week irrigation interval. Applied irrigation water and evapotranspiration of 100%CWR treatment were 118 and 125 mm, respectively. The highest average lettuce yield of 7.8 ton da-1 was obtained from the full-irrigation treatment (Kp1). Significant differences were not observed between Kp1 and Kp2 treatments in terms of lettuce yield. Maximum irrigation water use efficiency and total water use efficiency were obtained from Kp4 treatment respectively with 0.117 and 0.074 ton da-1 mm-1. Yield response factor (ky) was found to be 0.88. The research results showed that a 7 day irrigation interval with Kp2 treatment could be used for irrigating lettuce under the unheated greenhouse conditions without any significant yield loss but increased water use efficiencies.

Abstract

In this study, a local weaning meal made up of maize, soybean and groundnut was formulated. The components were each in proportion of 2:1:1. Material balance method was used to predetermine the nutrient to meet standards in the final product. The proximate result of the formulated weaning meal showed that protein content (%) was 20.60, with 9.30 fat and 66.40 carbohydrate, 1.39 ash content, 2.32 moisture content. Though the moisture increased marginally compared to changes in weeks, the microbial load count (Cfu/g) did not change significantly. Meanwhile, the level fell below allowable recommended range of 25- 250 cfu/g. The formulation was evaluated by 15 panelists using a 9 – point hedonic scale and statistical analysis carried out on their responses. The mean scores from sensory evaluation showed that the formulated sample was accepted. These results provide a basis for the development of an acceptable complementary food that can provide the required protein energy level that are essential basic nutrients, and can meet infants growth demands.

Abstract

The objective of this project to identify the temperature effect on the solar photovoltaic (PV) power generation and minimize the temperature effect. The photovoltaic (PV) cells suffer efficiency drop as their operating temperature increases especially under high insulation levels and cooling is beneficial. A selected photovoltaic module’s the Voc, Isc and Pmax will be determined for varying temperature when Irradiation is constant. (Isc = Short-circuit current (A), Voc = Open-circuit voltage (V) and Pmax= Maximum power (W)) and Compared Voc, Isc, Pmax from the Standard rest condition. From the gathered data, the best position (height difference between roof top and solar panel) for the solar panel to avoid temperature increasing will be determined and a suitable photovoltaic thermal system (active cooling) for solar panels.. These techniques are anticipated to contribute towards wider applications of PV systems due to the increased overall efficiency.

Abstract

The heavy post-harvest losses and quality deterioration caused by storage pests are a major problem facing agriculture in developing countries such as Nigeria (Adedire and Ajayi, 1996; Parwada 2018). Sitophilus zeamais (maize weevil) is a field and storage pest of maize of economic importance in several parts of Africa. Controlling of the pest by use of synthetic pesticides is raising serious concern on the environmental safety and consumer health hazards. A laboratory experiment was done to assess the insecticidal effects of and leaf powders then their combination in controlling the S. zeamais. A Completely Randomised Design (CRD) with three application rates (5.0g/200 g grain, 10.0g/200g grain and 15.0g/200g maize grain) of the botanicals (stem bark and leaf powders and combination of stem bark and leaf powders) replicated three times was used in the assessment. A synthetic chemical (Malathion dust at 0.1g) was used as a check pesticide to compare the efficacy of the botanicals on the maize weevil. The results showed higher weevil mortality and lower grain loss in the Malathion than in the botanicals (P≤0.05). However, there was no significant difference between Malathion and G. arborea stem bark powder at concentration 15.0g which recorded highest mortalities of 90% on day three. This was followed by leaf powder and combination 76.67% and 60.0%) respectively. The G. arborea stem bark powder at 15.0g/200g grain showed pesticide potentials in controlling the S. zeamais and therefore can be used to protect maize grain damage from the weevil during storage.

Nigerian Monocultural Economy and the Need for Economic Diversification for Sustainable Economic Development

 

Ezeocha, Chukwuemeka Maurice.

Department of Banking and Finance, Federal Polytechnic, PMB 1012, Kaura Namoda, Zamfara State, Nigeria

 

Abstract

This paper assesses the nature of the oil-based mono-cultural economy of Nigeria viz-a-viz its implications. Nigeria’s economy has over the years remained a mono-cultural economy, heavily dependent on crude oil export for economic development. There have been sincere calls for diversification of the economy, especially since the sharp and continuous decline in crude oil prices in mid-2014, which arguably, led to recession in the second quarter of 2016. The paper therefore re-enforces and justifies this call, by clearly highlighting the reasons why Nigeria urgently needs to diversify its economy away from oil resource dependency. If Nigeria will not change the oil dependency economy, there will be grave implications for its economic development. With oil price volatility and decline on the global market, coupled with disruptions in oil supply affecting the international oil market in some ways, huge reliance on oil revenue has seen Nigeria being challenged in her quest for development. The research makes use of secondary data to assess the situation and also draws the conclusion that with oil price volatility and decline on the global market Nigeria needs to diversify her economy as reliance on a basic resource discourages growth. It is therefore recommended among other things, that Governments at all levels should design pragmatic and workable programmes that will revitalize the agricultural sector and promote agricultural productivity. More so, every geo-political zone and state in Nigeria has unexplored or under-utilized mineral deposits due to great focus on the oil sector and should therefore, develop other aspects of the economy where they have comparative advantage, subject to constitutional constraints.

Abstract

The suitability of baobab flour as a binder and comparative studies of its binding potential with some locally available binders in sawdust briquetting were carried out. The other binders studied were cassava starch and cow dung. Out of the three binders, the Baobab flour is the non-common binder which is being introduced to determine its suitability as a binder in sawdust briquetting and to compare it with the others. Nine different saw dust briquette samples were produced, samples A-I with different binder compositions. Samples A, B, and C contained only cassava starch, cow dung and Baobab flour as binder respectively while the other samples D-I contained blend of the binders at different formulations as presented in Table 1. All the binders used were found to have good binding potential for briquette production and can be used alone or as a blend in proportion with the other binders. However, Briquette sample C with pure baobab flour binder: (0% cassava starch; 0% cow dung and 30% Baobab flour) has the highest calorific value of 22.0 MJ/kg and the highest thermal efficiency of 35.48%. The briquette sample F with binder blend formulation of: (4.5%% cassava starch; 4.5% cow dung and 21% Baobab flour) on the average showed the optimal briquette qualities (Moisture content, ash content, shatter index, compressive strength, calorific value and thermal efficiency) being tested.

Department of Electrical/Electronics Engineering, Federal Polytechnic Oko

 

Abstract

This paper is describes the soft and smooth start to a 3 phase induction motor. The three phase induction motor during the initial starting condition draws up much higher current than its capacity and the motor instantly reaches the full speed. This results in a mechanical jerk and high electrical stress on the windings of the motor. Sometimes the windings may get burnt. The prototype have been developed to give a soft start to the induction motor based on the SCR firing triggered by heavily delayed firing angle during starting and then gradually reducing the delay till it reaches zero voltage triggering. This results in low voltage during start and then gradually to full voltage. Thus the motor starts slowly and then slowly picks up to full speed. The working prototype consists of a six anti-parallel SCRs, two for each phase, the output of which is connected to a set of lamps representing the coils of a 3 phase induction motor, capacitors, comparators, opto-isolators to trigger the SCRs etc .This can be enhanced by using IGBTs in place of SCRs with PWM control to reduce harmonic distortions often encountered in SCR triggering mechanism for future scope. The implementation of hardware model has been discussed in this paper.

Abstract

A study for fungal post-harvest rot pathogens of Irish potatot rot was investigated in four markets in Mubi Adamawa state, (mubi main market, kasuwan kuturu, new market and kasuwan gada) with objectives to identify the fungal pathogens of potato, to determine the incidence and the severity of the pathogens and to determine the in-vitro and in-vivo control of the three plant extracts (garlic oil, neem oil andTridax leaf ash) on the pathogens. One hundred and twenty Irish potatoes were randomly collected from the four markets and taken to laboratory of Plant Science, Modibbo Adama University of Technology Yola. Industrial potato dextrose agar (PDA) was used for the isolation of fungi. Completely randomized design (CRD) was used in three replicates for each of the treatment. Data collected were subjected to Analysis of Variance (ANOVA) and least significant difference (LSD) separated means that were significant. The symptoms of the disease were observed and associated organisms isolated and identified through pathogenicity test and the following pathogens were identified; Aspergillus flavus, Thielavia terricola Rhizopus stolonifer and Scoupulariopsis brevicaulis. A severity test on the pathogens was carried out with the sample size of twelve potatoes by measuring the level rot of the pathogens. Result showed (p=0.0001) that Thielavia terricola was the most severe (13.11mm) and Aspergillus flavus with least of (7.97mm) and no significant between Rhizopus stolonifer and Scoupulariopsis brevicaulis. The incidence of potato rot in four markets revealed a high percentage rot in kasuwan gada (12.65%), mubi main market (7.65%), kasuwan kuturu (6.5%) and new market (5.25%). Control trials both in-vitro and in-vivo with garlic oil, neem oil andTridax leaf ash were found promising, and their different concentrations (5ml, 1oml and 15ml) were also found promising and the effectiveness of the control increased as the oils and quantities of ash increased. Essential oil of garlic, neem oil and Tridax leaf ash extracts proved effective in the control of potato fungal rot and are recommended as an alternative to synthetic fungicides which are often hazardous and costly.

Abstract

Cities of contentment has not been available or being satisfactory over the years. This is shown by the prevalence of disparity on a settlement that is characterized by two distinct posture. The emergence of equitable cities development is as a result of disparity within an area. This two different areas have characteristics with different set-up which is not supposed to be so with the rate urbanization. The scenario of different settlements having un-satisfactory features or the same settlement with two different characteristics is a situation where one area seems to be planned and the other part is not. The other part that is organic is forced to trespass into the planned area to benefit from one thing or the other. While it happens like that, the organically emerged areas become an eyesore with much burden on the planned area. This happening indeed contravene planning intention though they are said to have historical background but with problems of equidistance in distribution of facilities, utilities and services. The concept of equitable cities is based on equitable development including both environmental justice and smart growth void of disparity as observed by Levy, (2009). The intention of this paper is to see how development can be spread in equity.

The objective of this paper is to design, fabricate and testing of a fully automated egg incubator using electric, battery and inverter. Microcontroller based egg incubator system which is able to automatically maintain the environment which is optimum for embryo growth. The system has a temperature sensor which is able to monitor the temperature inside and outside the incubator and this data is sent to a microcontroller. The microcontroller, with the help of relays controls an incandescent lamp and an air circulating fan to maintain the egg temperature from 36 to 38.5°C. The microcontroller also has a user-programmed timer to control a gear motor for turning the egg holder. Egg incubators with regular, effective and efficient operation have the capacities of providing enough poultry birds, which can serve every household in Nigeria with sufficient amount of protein on daily basis. Although many commercial incubators in Nigeria have folded up due to epileptic and erratic electricity supply which disrupts and impairs the operation of the incubators and reduce their level of performance resulting into low production and cost of poultry birds. In order to ensure an uninterrupted power supply and keep egg incubators in operation, an electric, battery and inverter powered poultry egg incubators were developed. The developed electrical/ battery and inverter incubator will be 0.98*0.73*1.31m in size with capacity for 1000 chickens egg. The size of the charge controller, batteries and inverter power designed and used was 400W.

Abstract

The profit of any manufacturing company is dependent on how much the firm can cut on its production cost. So, Minimizing production cost in a manufacturing company will increase the profit of the company. The production cost of deteriorating items is dependent on the cutting parameters including the holding, shortage, set up and production cost. If these parameters are set to the optimal level, then, the overall cost of the production can be minimized. This study develops profit and production inventory model for deteriorating items with constant demand, Shortages are allowed in the inventory system. The aim of this model is to determine the optimal cycle length of each product such that the expected total cost is minimized. The necessary and sufficient conditions for the existence and uniqueness of optimal solutions are also determined. To validate the optimal solution, numerical example is provided. Sensitivity analysis is carried out to explore the effect of changes in the values of different parameters.

Jibrin Ubale Yahaya, PhD

Department of Political Science, National Open University of Nigeria (NOUN)

 

Abstract

Turkey has been diplomatically and militarily involved in the Syrian Civil War since its outbreak in 2011. Initially condemning the Syrian government at the outbreak of civil unrest in Syria during the spring of 2011, the Turkish government’s involvement gradually  into military assistance for the Free Syrian Army in July 2011, border clashes in 2012, and direct military interventions in 2016- 2017, 2018, and in 2019. The military operations have resulted in the Turkish occupation of northern Syria since August 2016. After a decade of relatively friendly relations with Syria during the prior decade, Turkey condemned Syrian President Bashar Al-Assad over the violent crackdown on protests in 2011 and later that year joined a number of other countries demanding his resignation. From the beginning of the war, Turkey trained defectors of the Syrian Army in its territory under the supervision of the Turkish National Intelligence Organization (MİT), among who emerged the Free Syrian Army (FSA) in July 2011. In May 2012, the Turkish National Intelligence Organization (MİT) began arming and training the FSA and provided them with a base of operations. Tensions between Syria and Turkey significantly worsened after Syrian forces shot down a Turkish fighter jet in June 2012, and border clashes erupted in October 2012. On 24 August 2016, the Turkish Armed Forces began a declared direct military intervention into Syria, mainly targeting the People’s Protection Units but also the Islamic State of Iraq and the Levant. Human rights groups, including the Syrian Observatory for Human Rights and Human Rights Watch have reported that Turkish troops have killed 443 civilians fleeing the civil war in Syria. This includes 78 children and 44 women killed by Turkish border guards. This paper has uses various literatures on the subject matter and reviewed it to investigate the problem at hand. The researcher was of view that Turkey-Syria relation has growing serious bad signals bad diplomatic relations since 2011 after Syrian unrest and involvement of Turkey government in to refugee and military assistance that led to Turkish army occupying some places around the country’s borders that make Syrian army to revolt in order to protect their territory. For peace to be maintain in Syrian there is need for Russia , US,  French and other superpowers  countries to withdraw their hands from the conflict and allowed the two countries to diplomatically resolved their differences.

Abstract

With an aid of validated copies of structured questionnaire, charcoal tree species, method of charcoal production and conservative effort of those involved in charcoal business were examined in Bauchi State, Nigeria. Out of the twenty Local Government Areas (LGAs) of Bauchi State, six were randomly selected using stratified   according to the prevailing tree ecological zones which include: Northern Guinea savannah, Sudan Savannah and Sahel Savannah. The LGAs selected were Toro and Dass from Northern Guinea Savannah, Kirfi and Warji from Sudan Savannah and, Jama’are and Dambam from Sahel Savannah. The study reveals that twenty nine (29) forest tree species from eighteen botanical families were being used FOR charcoal production. The families that had the highest utilization were Fabaceae, and Combretaceae with four species each used for charcoal production. Moraceae had three species; Caesalpiniacea, Verbanaceae and Anarcadiaceae had two species each. The families of melaceae, Sapotaceae, Myrtacea, leguminaceae, balanitaceae, Bambacaceae, Rhamnaceae, Euphobiaceae, Boraginaceae, Ebonaceae and Burseraceae had the least of one specie each. The results also shows that those involved in charcoal business have never participated in tree planting for environmental rejuvenation but have indicated their interest to take part in future when planting stock and extension services will be made available. In order to lessen the utilization of charcoal, provision of improved stoves and alternative to fuel wood were recommended among others.
