Item Comparative assessment of the changing pattern of land cover along the Southwestern coast of Nigeria using GIS and remote sensing techniques(Elsevier, 2022) Fashae, O. A.; Tijani, M. N.; Adekoya, A. E.; Tijani, S.A.; Adagbasa, E. G.; Aladejana, J. A.The changing pattern of land cover is increasingly becoming of global concern in the sustainable management of environmental resources. Different facets of the natural ecosystem continue witnessing devastation orchestrated by rapid population growth and urban expansion in the face of climate change. This study examined the contribution of human’s to the global environmental change by assessing the dynamics of land cover between 1984 and 2017 while predicting the future extent of land cover pattern for 2047 at the Epe and Igbokoda areas on the coast of southwestern Nigeria. Landsat Thematic Mapper (TM), Enhanced Thematic Mapper Plus (ETM + ), and Operational Land Imager (OLI) imageries of 1984, 2002, and 2017 respectively were acquired from the USGS to analyse the land cover changes. Supervised classification was done using the maximum likelihood classifier of Terrset version 18.31. The Change Demand Modelling of Land Change Modeller (LCM) in Terrset integrates the Markov chain for future predictions for 2047. The Epe area which typifies a rapidly urbanizing coastal environment recorded an 84.6% increase in built-up area extent between 1984 and 2017, while the built-up area of the Igbokoda area increased by 103.8% for the same period. This increment corresponds to a decrease in the spatial extent of the forested wetlands with an increase in water bodies. Expansion of water body extents indicates the interaction between the elements of climate change such as incessant flooding and anthropogenic activities like deforestation, urban expansion through sand mining and dredging. Future prediction into 2047 connotes further worsening of the situation. Therefore, solution-based sustainable coastal management practices are recommended to salvage the impoverishing coastal ecosystems from further impairment.Item Determinants of utilisation of university of Ibadan agricultural research outputs among farmers in Oyo and Osun states, Nigeria(2021) Okanlawon, O. M.; Tijani, S. A.; Oguntade, M. I.The study assessed determinants of farmers’ utilisation of University of Ibadan (UI) Agricultural Research Outputs (AROs) in Oyo and Osun States, Nigeria. A multi-stage sampling procedure was used to select 176 beneficiaries of AROs in the study area. Focus Group Discussion and interview schedule were used for data collection on respondents’ socio-economic characteristics, knowledge, utilisation level and determinants of utilisation of UI AROs. Data was analysed using descriptive and inferential statistics like Chi square, PPMC, and multiple regression. AROs considered for the study were use of neem (Azadirachta indica) extract for pest management, rice-fish-poultry integrated farming system, processing of moringa oleifera powder and ruminant feed block meal pattern. Results reveal that respondents’ mean age household size were 40.05±35.48 years of 4.04±1.25 persons respectively. Respondents had mean farming experience of 7.92±5.26 years. The most utilised source of labour was family (63.0%) with mean farm size of 1.56±0.93 acres. Respondents’ knowledge (67.0%), and utilisation (55.7%) of UI AROs were high for innovations disseminated. Respondents’ marital status (χ2=5.99), sex (χ2=3.92), level of education (χ2=30.69); age (r=0.23) and income (r=0.79) were significantly related to UI AROs utilisation. Respondents’ knowledge (r=0.32) and benefits derived (r=0.80) were significantly related to utilisation of UI AROs. The determinants of utilisation of the AROs included educational qualification (β = 0.462), years of farming or processing experience (β=0.27), scale of production (β=0.33) and knowledge on utilisation (β=0.45). The study recommends that farmers be encouraged to improve on their level of education for better utilisation of disseminated agricultural research outputs.Item Determinants of vegetable women farmers’ economic security in Boke region, Guinea(2021-06) Tijani, S. A.Vegetable production had been a major source of livelihood among women in Guinea. This study therefore, assessed the determinants of vegetable women farmers’ economic security in the Boke region of Guinea. A multi-stage sampling procedure was used to select 180 respondents for the study. Data was elicited from the respondents with the aid of interview schedule and analysed using descriptive and inferential statistics. The results revealed that average household and farm size cultivated respectively were 8.54±3.55 persons and 1.17±0.62 ha. Personal land (71.7%), household (97.2%) and hired labourers (84.4%) were used by respondents. Almost all (95.0%) relied on personal savings for the finance of vegetable farming. Prominent constraints against vegetable production were inability to access credit at banks (x̅=1.87), lack of storage (x̅=1.87) and processing (x̅=1.86) facility. Vegetable enterprise was not profitable for 53.3% of respondents. Income from vegetable farming was neither adequate (99.4%) nor stable (100.0%). Average annual expenditure ($4,664.92±1723.75) was higher than annual income ($704.49±1,379.98) Almost all the respondents were economically insecure (98.9%) thus unsustainable livelihood and inability to cope with emergencies. Significant predictors of economic security among respondents were household size(β=-0.229), use of personal land (β=-0.188), use of rented or lease land (β=-0.205), use of family land (β=-0.142), use of family/ hired labour (β=0.159), annual income (vegetable) (β=0.596) and the number of vegetables grown (β =-0.150). The study recommends that farmers be encouraged to form cooperatives in order to facilitate access to credit facilities, need for the establishment of cottage industries and promotion of value addition.Item Training needs of communication officers of agricultural and rural development agencies for entertainment-education script writing in Southwestern Nigeria(Institute of Agricultural Research and Training, Obafemi Awolowo University, 2020) Olajide, B. R.; Tijani, S. A.; Ojomuyide, T. O.The use of Entertainment-Education (EE) for information dissemination in agricultural extension agencies requires that key frontline professionals are trained in EE script writing, therefore the training needs of communication officers in EE script writing was probed in this study. All (42) communication officers of agricultural development agencies in the study area were interviewed. Data were collected using questionnaire to elicit information on communication officers' socioeconomic characteristics, awareness of the components of EE script writing, perception of integration of script writing skills for agricultural information dissemination and training needs for EE script writing in agricultural information dissemination. Data were analysed using frequencies, percentages and means. Results indicate that respondents' mean age was 43.0±6.8 years, 38.1% had Bachelor’s Degree and were mostly male (64.3%). Most respondents were aware of the components and sub-components of EE scriptwriting, 52.4% had favourable disposition to the concept and had most training need on message, character and plot components. The study concludes that communication officers are abreast of the components and subcomponents of EE scriptwriting and are favourably disposed to the concept of EE script writing. Training on EE script writing for communication officers of agricultural development agencies should focus on message, character and plot components.Item Characteristics of shea butter processing in Niger State, Nigeria(2020-10) Tijani, S. A.; Sanusi, M. K.The study examined the characteristics of Shea Butter processing and factors associated with the output in Niger states, Nigeria. Two stage sampling procedure was used to select 315 respondents. Interview schedule was used in data collection. Data collected were analysed with percentages, Chi-square, the Pearson Product Moment Coefficient (PPMC) and simple regression model at α 0.05. The result revealed that the majority (80.6%) of the respondents used semi-mechanised method in processing Shea butter. The average unit price of Shea butter was N476.07K per Kilogramme, while the average income was N439,650.37K per annum. Processors had low level of accessibility to modern processing technologies (66.2%) and more than half (64.8%) of the processors were producing at low level. Lack of credit facilities and high cost of processing equipment were identified as severe constraint to Shea butter processing. There were significant relationship between level of education (χ²=11.18, p≤0.05), level of engagement (χ²=8.71, p≤0.05), income (r=0.819, p≤0.05) and accessibility to modern Shea butter processing technologies (r=0.164, p≤0.05) with level of Shea butter processing output. The major determinants of Shea butter processing output were income, household size, unit price and accessibility to modern processing technologies. Financial institutions should provide soft loans to Shea butter processors to acquire inputs and equipment. Similarly, government agencies should provide Shea butter processing equipment to the processors to improve access to the technologies that could lead to increase Shea butter production in Niger state.Item Effects of small scale irrigation on women farmers’ well-being status in Sikasso region of Mali(2020-10) Tijani, S. A.; Kone, D. M.This study examined effects of small scale irrigation on women farmers’ well-being status in Sikasso Region of Mali. A multi-stage sampling procedure was used to select 160 respondents (user and non-users) while data were collected using interview schedules and analysed using percentages, mean, standard deviation and t-test. Major constraints facing users are crop damage (x̅ =2.68), unavailability of input (x̅ =2.41) and inadequate credit facility (x̅ =2.15). Sixty percent, 98.8%, 85.0%, 85.0% of users have higher level of material, economic, mental and social well-being, respectively compared to 25%, 0.0%, 68.8% and 35.0% of non-users with similar status. The overall wellbeing of 73.8% of users were better-off compared to 11.3% of non-users. A significant difference (t= 11.110) existed in the wellbeing status of users and non-users. Utilisation of small-scale irrigation systems had positive effects on the mental, social, economic and material wellbeing of the users. There is need to extend small scale irrigation to non-users.Item Extension paradigm shift: a drive for agricultural productivity and value addition in Nigeria(Ibadan University Press, Publishing House, University of Ibadan, Ibadan, Nigeria, 2021-02) Tijani, S.
