- ItemOpen AccessANALYSIS OF LANDUSE/COVER CHANGE IN OMOTOSHO FOREST RESERVE, ONDO STATE, NIGERIA(DEPARTMENT OF GEOGRAPHY, FACULTY OF SOCIAL SCIENCE, OBAFEMI AWOLOWO UNIVERSITY., 2022) SUNDAY SEFUNMI ADEFUNRINThis study identified land use/cover in Omotosho Forest Reserve, Ondo State, Nigeria, and analysed changing pattern of land use/cover in the forest reserve. It also measured the extent of forest loss to different land uses, and examined the drivers of land use change in the forest reserve. These are with the view to determining the extent of forest degradation in the forest reserve. The study adopted descriptive survey research design and used primary and secondary datasets. The primary data included the coordinates of selected features (settlements, rivers and rocks) in the forest reserve, and these were obtained using a handheld Global Positioning System (GPS). They also included the responses of 36 Key Informants (six purposively selected adults (aged > 30 years) persons from six settlements around forest reserve). The secondary data were Landsat ETM+ 2000, Landsat OLI 2010, Sentinel 2015 and Sentinel 2020 satellite images of the study area. The satellite imageries were first processed and georeferenced using the coordinate values of the selected features, before they were analysed using remote sensing and Geographical Information Science procedures in ArcGIS (10.4 version). Derived values from the analysis were analysed using frequency and percentage distribution techniques. Responses of the key informants were analysed using content analysis. The results showed that the identified dominant land use/cover in the study area were dense forest (29,727 ha), shrubs (14,348 ha), farmland (13,462 ha), settlements (8,252 ha), open spaces (3,014 ha) and water bodies (699 ha). Results also showed that while farmland increased in area cover between the period of study (from 9,247 ha – 13,462 ha), areas covered by settlements also increased (from 4,718 ha – 8,252 ha), open spaces increased in area covered from (984 ha – 3,014 ha) and scrubs increased from 10,108 ha – 14,348 ha), amount of
- ItemOpen AccessThe contribution of Benue State House of Assembly in the promotion of good governance [1999-2021](Department of political science, Faculty of social sciences, Obafemi Awolowo University., 2023) ADOGA, AgboThe study ascertained the level of relationship that exists between the representative and the people they represent, identified the way by which Benue State House of Assembly equitably distribute public goods to its citizens, and examined the challenges faced by the Benue State House of Assembly (BSHA) in ensuring that good governance for the people of the state is attained or actualized. These were with a view to determining if the Benue State House of Assembly had lived up to its constitutional responsibility and the expectations of the people and able to promote good governance in the state. The study concluded Benue State House of Assembly (BSHA) have failed to live up to the expectations and responsibilities due to corruptions and political patronage, which limit their ability to promote good governance in the state.
- ItemOpen AccessPrevalence and determinants of unmet need for contraception among young women in southwestern Nigeria(Department of Demography and Social Statistics, Obafemi Awolowo University, 2023) JAMES, Favour OsinachiThis study assessed the prevalence of unmet need for contraception among young women, examined the relationship between socio-demographic factors and unmet need for contraception, investigated the determinants of unmet need for contraception, and explored other socio-cultural factors underlying unmet need for contraception among young women in Southwestern, Nigeria. These were conducted with a view to understanding the causes as well as other socio-cultural factors underlying unmet need for contraception among young women in the research area. The study concluded that fear of side effect, finance, misinformation about contraception and fear of death were the underlying factors of unmet need for contraception among young women in Southwest Nigeria.
- ItemOpen AccessPetrophysical evaluation of two reservoir sands in five wells in the western part of the Niger Delta.(Department of Geology, Faculty of Science, Obafemi Awolowo University, 1996) Abegunrin Omotola OmoladeThe petrophysical characteristics of two reservoir sands in five wells drilled in western part of the Niger Delta were studied using borehole geophysical (open hole) logs.
- ItemOpen AccessEnergy consumption and sectoral output performance in Nigeria (1981-2019)(Department of economics, Faculty of social sciences, Obafemi Awolow University., 2022) ADEYEMI Owolabi WilliamsThe study examined a trend analysis of energy consumption and sectoral outputs in Nigeria,identified the direction of causality between energy consumption and sectoral outputs in Nigeria within the period of 1981-2019, and also determined the effect of energy consumption on sectoral outputs. These were with a view to examining the relationship between energy consumption and sectoral output performance in Nigeria.The descriptive research design, and annual secondary data for the period of 1981-2019 were employed in the study. Data on real Gross Domestic Product (GDP), energy consumption, labour force, exchange rate and agricultural, crude petroleum & mining, manufacturing, construction, and trade & services outputs for the study period were sourced from World Development Indicators (WDIs, 2021) published by the World Bank, and Central Bank of Nigeria (CBN) Statistical Bulletin. The study used descriptive statistics in form of tables and graphs, while the autoregressive distributed lag (ARDL) error correction mechanism model was adopted for the short run effect analysis, and the Fully Modified Ordinary Least Squares (FMOLS) with allowance for structural breaks was adopted for long run effect analysis. The results, in relation to the trend analysis, revealed that the trend of sectoral energy consumption demonstrated a divergent pattern from those of the key sectors of the economy. Specifically, turbulent trend patterns were observed for the energy consumption by each sector, which signified different energy availability and consumption patterns for the sectors, whose outputs showed a somewhat slow but progressive growth. On the issue of causality, the study established a unidirectional causality running from agricultural output to energy consumption (χ2= 11.1569, p < 0.001). Similar finding was established between trade and services output and energy consumption (χ2 = 8.8806, p < 0.001). However, a bidirectional causation was established between energy consumption (χ2 = 31.7560, p < 0.05) and manufacturing output (χ2 = 4.1180, p < 0.0424). The study further established no causality between energy consumption and both crude petroleum & mining, and construction output. On the effect of energy consumption on the disaggregated sectors of the economy, the study established that the agricultural sector experienced positive and significant effect of energy consumption (t = 3.3874, p < 0.01). However, a study further established that energy consumption has significantly negative effect on the construction sector output (t = -2.13, p < 0.05), while it also revealed that energy consumption has positive but insignificant effect on the trade & services sector. In the long run, however, the study reveals that energy consumption has both positive and significant effect on agricultural output (t = 5.49, p < 0.01), manufacturing output (t = 10.03, p < 1), construction output (t = 2.79, p < 0.01), and trade & services output (t = 18.82, p < 0.01). The study concluded that though there is positive relationship between energy consumption and sectoral performance in Nigeria, the contribution of the sectors to Nigeria’s economic growth is low, which is due to inadequate energy consumption.
