Purpose This study aims to determine the impact of resource use behaviours of students of a public university in Ghana on ecological sustainability. It examines the land area required to provide the resources used and also to assimilate the wastes produced. It also suggests an effective way to initiate participative discussions on environmental sustainability and consequences of resource use in a university setting. Design/methodology/approach This study adopts a mixed methods approach to gather and analyse data on students’ lifestyles concerning ecological footprint. The data was analysed using the Predictive Analytics Software and a modified version of the ecological footprint analysis (EFA). Findings The current ecological footprint of students in the university is not environmentally sustainable. The sample population had high average ecological footprint of 3.62 hectares, representing an ecological impact score of 135.85. The findings provide lessons on how universities and analogous institutions interested in sustainable practices could foster ecologically sustainable development. Research limitations/implications Additional data collection methods such as a longitudinal study would provide a more comprehensive assessment of the impact of resource use behaviour of students in a public university in Ghana on ecological sustainability. Social implications EFA and findings can support universities to effectively integrate sustainability practices into their policies and practices to help students contribute to making society more sustainable. Originality/value This is an original research and makes a contribution to EFA and sustainable practices of public universities in Ghana.
Aims: Suitability of land for growing crops, which considers the spatial distribution of soil characteristics, is an important factor to consider in order to maximize yields and ensure judicious land-use planning. This study was conducted to assess the suitability of Nzema series according to Land Suitability Classification for rainfed rice cultivation. The study was undertaken at Nkrankwanta lowland in the Dormaa West District, Ghana. Methods: Two pedons were dug at a depth of 0-140 cm for both sampling locations. A total of 50 soil samples were collected at a depth of 0-20, 20-40, 40-60, 60-100, and 100-140 cm depth. Suitability assessment was done using the FAO Land Quality Index with input parameters including pH, texture, stoniness, nitrogen, depth, organic carbon, slope, and drainage. Results: Chemical analysis revealed that nitrogen, phosphorus and organic matter were generally low. The results showed that pH for both pedons ranged from very strongly acidic to slightly alkaline (4–7.8) which could be as a result of leaching of basic cations due to the regular flooding of the lowland. The two pedons are deep >140 m and the drainage is imperfect to poorly drained. Soil Quality Index was 0.8 whilst Nutrient Availability Index was 0.05, indicating highly suitable and marginally suitable land for rice production respectively. Conclusion: Based on this analysis, Nkrankwanta lowland is marginally suitable (0.04) for rice production. The soil is potentially highly suitable if continuous monitoring of the pH status is carried out. Nutrient management is recommended to improve the low fertility status of the soil.
Background. The global discourse on plastic waste generation and disposal has over the last two decades, gained traction with the aid of research-based evidence. Though observed globally, the situation is quickly deteriorating in developing countries such as Ghana. In Ghana and Africa as a whole, rapidly increasing population and rural to urban migration have been cited as factors that exacerbate the existing struggles with plastic pollution. This study aimed at identifying the determinants of unsafe plastic waste disposal among households. Methods. The study was carried out in three communities in Tamale in the Northern Region of Ghana. Data were collected from 270 randomly selected households through household surveys, key informant interviews, and direct field observations. Results. The study revealed that the majority (63.3%) of the total respondents used and disposed of their plastic waste “unsafely.” The analysis showed that the education level and household wealth were significant determinants of unsafe plastic disposal. Conclusion. The study concludes that challenges of plastic waste management are not limited to economic, technical, and institutional factors, but social factors such as human behavior are key aspects of waste management that need attention. The study, therefore, recommends strict enforcement of sanitation by-laws, promotion of education, and provision of alternatives to plastics that will minimize the need for importing and manufacturing plastics, as potential steps towards addressing unsafe disposal of plastics in the domestic environment.
Land use conversion significantly impact on sensitive soil quality parameters such as microbial biomass and soil microbial quotient. Therefore, soil microbial biomass and physicochemical properties were compared under three different land use systems namely agricultural land, degraded mine land and an adjacent natural forest in the Newmont Gold Ghana Limited concessional areas, Kenyasi, Ghana. In our field experimentation, an area of 300 m2 was demarcated in each land use type for soil sampling. In each of the land use type, we collected soil 5 samples at a depth of 0-15 cm in both the dry and wet seasons respectively. Parameters we measured included soil bulk density, pH, particle size distribution, organic carbon, total nitrogen, available phosphorus, microbial biomass carbon and nitrogen, and moisture content. Our results revealed that land use type significantly impacted on soil microbial biomass and physicochemical properties. Microbial biomass carbon and nitrogen was higher in the forested land compared to the agricultural land and degraded mine land, which was due to relatively higher amounts of litter inputs. Microbial biomass carbon decreased between 20.23 - 88.36% when land use changed from forested land to other land uses. Significant positive correlation was observed between soil microbial biomass and water content, soil organic carbon, phosphorus, clay, nitrogen. Generally, seasonal variation in our study area did not influence soil physical and chemical properties, however, it significantly affected microbial biomass indices. Findings of our study further revealed the importance of forested area in the maintenance of soil quality parameters.
