The Impact of Urban Land Use Changes on the Morphology of the New Calabar River Catchment, Port Harcourt Metropolis, Nigeria
Full text linkThe 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
The Acceptability of the Proposed Design of Bungang-Api Park: Community Aquaculture Chinampas Utilizing Avicennia Officinalis as Crop Support
Full text linkChinampas are an effective way to increase access to new crop resources that benefit ecosystems, sustainability, livelihood, and food security. Chinampas are rectangular mud-artificial islands built in bodies of water where crops are grown. They are typically constructed of willow trees, and only one native can be found in the Philippines. Using Avicennia officialnalis, also known as Api-API, which grows in firm mud as a substitute for willow trees, along with landscape architecture, the integration of green space, mangrove nurseries for reforestation, and the reduction of aquaculture—a significant cause of mangrove loss—is a potential building for chinampas in the Philippines setting. The study aims to determine whether a design is acceptable to the residents of the chosen setting and proposed design, Barangay Sto Rosario, Paombong, Bulacan, Philippines, in terms of (1) area usability, (2) design appreciation, and (3) environment, with 264 samples responding to a validated questionnaire consisting of 13 Likert scale questions for quantitative data and three open-ended questions, extracted with thematic analysis for qualitative data. In the research setting, 148 respondents were required to complete the survey. The results show that the design is acceptable. Some aspects were low, but due to the respondents' unawareness of the field and objective of design and landscape architecture, it appears to be welcoming to the respondents' acknowledgement. Respondents also input their perspectives and thoughts about its possibilities for economic values, the full potential of green spaces, and its feasibility and promotion of biodiversity

Water Disinfection Via Zinc Oxide (ZnO) Nanowires Chemically Fabricated on A Modified Polyurethane Substrate
Full text linkNowadays, water contamination is a big issue due to concerns about health and water scarcity. Unfortunately, most water for human consumption is contaminated with various pathogenic microorganisms that cause water-related diseases. Most traditional chemical and physical disinfectants are energy- and time-intensive and prone to generating harmful disinfection by-products. The recent controversy about waterborne diseases and the safety of commonly used disinfection methods has renewed interest in other forms of disinfection. Low-cost, high-efficiency, and low-energy devices should be developed for potential water disinfection, enabling safe drinking water access. Recently, many researchers have been working on improving the scalability and economics of nanomaterial-based devices to overcome many of the limitations of using traditional anti-microbial agents. Herein, we develop a safe and efficient new nanomaterial decontamination device targeting bacteria in drinking water. Zinc Oxide (ZnO) Nanowires and polyurethane sponges were utilized as affordable and available materials that would lower the cost of the filtration device. The device is based on an electroporation method that applies a low voltage of ~6 V to inactivated bacteria in water. The performance of our device was optimized using different values of voltages, flow rates, microorganism concentrations, and various operation times. By relying on nanotechnology-enabled electroporation principles, this method aims to address the limitations of traditional techniques and offer a feasible solution, especially in areas grappling with contamination issues that lack water treatment infrastructure
