Hence, emergent technologies that are economically feasible and highly efficient must be studied and explored, with the aim of promoting better environmental and human life quality. Plants are known to remove heavy metal ions from wastewater. In this study, the potential of various parts of Moringa oleifera; dry pod, seed, fresh pod, root, bark, and leaves to remove As (III) and Hg (II) ions were investigated and the chemical composition involved in this biofiltration were<br>characterized using Fourier Transform Infrared (FT-IR) Spectroscopy. The various parts of Moringa oleifera used as biosorbent were pretreated before used as a biofilter. The removal of Hg (II) by the pretreated Moringa oleifera various parts biosorbents were higher compared to the removal of As (III) ions by the same parts. This research showed that Moringa oleifera various parts have the potential to be used in the removal of Hg (II) metal ions from wastewaters.</p> 2021-11-29T00:00:00+00:00 Copyright (c) 2021 JENRM http://jenrm.uenr.edu.gh/index.php/uenrjournal/article/view/181 Agriculture Data Logger Using GPS Equipped Wireless Sensor Network: A Model to Support Ghana Planting for Food and Jobs Program 2021-11-29T10:06:53+00:00 Joseph Owusu myowususq@gmail.com Kelvin Aidoo jenrm@uenr.edu.gh Emmanuel Kengel Dankwa jenrm@uenr.edu.gh Ebenezer Sarpong jenrm@uenr.edu.gh Nana Twum Duah jenrm@uenr.edu.gh <p>The Government of Ghana’s agenda to maximize food production in agriculture requires the need for the design and development of innovative agricultural systems. Due to the high demand for land for farming which will likely cause deforestation and global warming, coupled with restricted access to some farmland due to distance or pandemics such as COVID-19, there is the need to use technology to optimize farming through precision farming. This paper proposes a model of an agricultural data logger using a wireless sensor network for agricultural parameters collection. The system logs soil temperature, moisture, humidity, and light intensity, transmits and stores the data in a central server for decision making. The wireless sensor network constitutes two nodes and a base station. Each node is a standalone system with sensors; temperature sensor, soil moisture sensor, humidity sensor, and a light sensor. The base station receives information from the various nodes through its network-equipped system. The network system is well secured through proper encryption of data. Global Positioning System is deployed in the proposed system to generate the longitudes and latitudes of the individual nodes. The soil data collected is display on a website and a database is incorporated in the website design to keep records of previously collected data for analysis and better farming decisions. The system consumed low power through the use of a low-powered microcontroller, NodeMCU, and the implementation of the wake<br>and sleep mode of the sensor nodes.</p> 2021-11-29T00:00:00+00:00 Copyright (c) 2021 JENRM http://jenrm.uenr.edu.gh/index.php/uenrjournal/article/view/182 Effects of urban growth on historical land use/land cover changes in the Sunyani Municipality, Ghana 2021-11-29T10:19:25+00:00 Daniel Adusu adusudaniel@gmail.com David Anaafo jenrm@uenr.edu.gh Simon Abugre jenrm@uenr.edu.gh Abdul-Rahman Bunyamin jenrm@uenr.edu.gh <p>Geospatial techniques are very effective in establishing the extent of, and trends in human-induced land use/land cover (LULC) changes in urban areas globally. However, despite the rapid urbanization of Sunyani owing to the exponential rise in the city’s population, there are limited empirical studies on the effects of the rapid urbanization of the city on historical LULC changes and how that informs urban policymaking. Employing historical population data, supervised classification techniques, and remotely sensed Landsat data for the years 1986, 2000, 2005, 2011, 2015, and 2018, this study analyzes the extent to which the growth of the municipality has impacted the urban landscape. The municipality’s population has been growing with an intercensal population growth rate of 2.3%. LULC trends in our study were similar to development in most mid-sized cities across the world. The study recorded significant growth in area covered by built-up and farmlands resulting in a corresponding decrease in closed and open forest. The study, therefore, concludes that the rapid urbanization of the city results in the conversion of green spaces into other land uses with consequences for growth management, service provision, mobility, diversity and livability, conservation of species and ecosystems, and restoration of damaged environmental components. Consequently, the study recommends the strict enforcement of land use regulations to protect land uses that are under the threat of urban expansion to ensure sustainable development in the city.</p> 2021-11-29T00:00:00+00:00 Copyright (c) 2021 JENRM http://jenrm.uenr.edu.gh/index.php/uenrjournal/article/view/179 Mushroom Cultivation as an Alternative Livelihood in Artisanal Goldmining Affected Communities in Ghana 2021-11-23T08:24:16+00:00 Edwin Supreme Asare jenrm@uenr.edu.gh Jonas Ayaribilla Akudugu jenrm@uenr.edu.gh Michael Addaney michael.addaney@uenr.edu.gh Amos Apraku amos.apraku@uenr.edu.gh Alfred Ohenenana Appiah jenrm@uenr.edu.gh <p>This paper examines the potential of mushroom cultivation as an alternative livelihood for people who engaged in un-regulated artisanal goldmining (galamsey) in rural Ghana. Kenyasi, Gyedu and Ntotroso communities in the Ahafo region have experienced an upsurge of artisanal goldmining activities since Newmont Ghana Gold Limited (Ahafo Gold Mine) started a large-scale mining project in the area two decades ago. Using a case study and drawing on mixed methods approach, the results revealed that majority of the people who engaged in galamsey were already aware that mushroom cultivation is gainful and expressed interest in its adoption if the needed training and financial assistance were provided. Thus, relying on the concept of alternative livelihood, the paper argues that the cultivation of mushrooms presents a viable livelihood option for those desiring to move out of unregulated artisanal goldmining. The findings underscore the role that government and other stakeholders could play to address the menace: provision of skill training and financial support to enable them to create sustainable alternative livelihood in mushroom cultivation. The paper concludes that providing an alternative livelihood to illegal mining requires concerted efforts from both private and public sector role players.</p> 2021-11-29T00:00:00+00:00 Copyright (c) 2021 JENRM http://jenrm.uenr.edu.gh/index.php/uenrjournal/article/view/183 Analysis of Cost and Challenges affecting the Profitability of Frozen Fish Enterprise in Sunyani Municipality of Ghana 2021-11-29T10:38:16+00:00 Seyramsarah Blossom Setufe seyramsarah.setufe@uenr.edu.gh Samuel Henneh jenrm@uenr.edu.gh Kumordzi William Junior jenrm@uenr.edu.gh Solomon Essel jenrm@uenr.edu.gh <p>One of the greatest problems facing the small-scale frozen fish enterprises in Sunyani is their vulnerability to losses due to high operational cost and uncertainty of their income. This study was conducted to investigate the socio-economic analysis of small-scale frozen fish enterprises in the Sunyani Municipality. A descriptive research design was employed where 25 survey questionnaires were administered to frozen fish sellers to achieve the study objectives. The result of the descriptive analysis showed that Scomber japonicas (Saman) had the highest average cost (GH¢ 518.25) among the fish species with Trachurus trachurus (Kpanla) being the least (GH¢ 257.13). It was also known from the study that, the average cost of electricity (GH¢ 119.80), packaging (GH¢ 58.80), and transportation (GH¢ 53.13) per month were the various additional costs to frozen fish business and increases the price of the fish species. Also, the highest total average profit of the fish species was recorded for Oreochromis niloticus (GH¢ 310.77). The least average profit of the fish species was recorded for Pagellus bellotti (Wiriwiriwa)of (GH¢ 51.6636). The perishable nature of the fish was a severe barrier to the frozen fish business. This could be attributed to the poor electricity supply usually experienced in the study area which is highly needed for preserving frozen fish. Frozen fish could only be stored for a few hours in which case must be sold even when the price is not favorable, this account for the severe losses suffered by fish sellers in the study area. There should be a reduction of electricity cost and constant supply of electricity as these key issues influence the cost and pricing of frozen fish in the study area. It is therefore recommended that the regulations be put in place to mitigate erratic power supply.</p> 2021-11-29T00:00:00+00:00 Copyright (c) 2021 JENRM
