Abstract

The New Calabar River catchment has experienced significant alterations in land use and land cover patterns due to the fast population growth in Port Harcourt. This research investigated the influence of urban land use change on the morphological structure of the New Calabar River basin, which is experiencing rapid urbanization in Rivers State. The research utilized a combination of primary and secondary data sources, specifically satellite imagery and field measurements of the hydro-geomorphic channel's breadth and depth. The findings indicated a significant rise in urbanization, resulting in the encroachment upon various land uses, including water bodies, farmlands, dense forests, and wetlands. Moreover, correlation and regression analysis revealed a significant positive link between channel morphology, discharge, and urbanization index. Therefore, it can be argued that the urbanization index and discharge are crucial in determining the river channel's current channel form and size features. The study also demonstrated a positive correlation between discharge and channel dimensions, including width and depth. The stream channel has experienced an expansion in reaction to the modification of the natural soil caused by urbanization, leading to changes in the stream flow regime. Additionally, it has been observed that the segment of the New Calabar River that encompasses urbanized regions tends to have a comparatively more significant cross-sectional channel. Incorporating urbanization analysis and its impact on morphology has facilitated the implementation of diverse geospatial analyses and sustainable watershed management in the basin.

Abstract

Purpose: The study is aimed at determining the impact of vocational-technical education on youths’ socio-economic development. Methodology of Research: Descriptive design was adopted in carrying out the study, with 4 research questions and hypotheses, 6,003 students of the population from the 12 vocational-technical schools in the state, a sample of 400 students, reliability coefficient of 0.72. Mean and standard deviation were used to answer the research questions; z-test was used to test the null hypotheses at a 0.05 Alpha level of significance. Results: The study revealed that vocational-technical education brings about economic development, skill acquisition, employment opportunities, aside from poverty reduction in Port Harcourt Metropolis. The study recommends the provision of infrastructure, adequate funding, and proper implementation of policies in vocational-technical schools in Rivers State, Nigeria. Limitations: This study was limited to the 12 existing public technical-vocational schools in Rivers State, Nigeria. Variables such as skills acquisition, economic development, employment opportunities, and poverty reduction were examined. Contribution: The study will expose the youths to various opportunities and possibilities, helping them to channel their strength and energy to reasonable economic activities. By so doing, social vices will be controlled.
