This paper employs panel cointegration technique to investigate the long-run relationship between carbon emissions and five impacting factors (per capita GDP, primary energy consumption, international trade, fossil proportion, and quadratic per capita GDP) in 50 representative developing countries during 1995-2017. The empirical findings confirm the existence of long-run equilibrium, and the regressing coefficients of fully-modified OLS (FMOLS) indicate that (a) impacting features of the inverted Ushaped curve of Environmental Kuznets Curve (EKC) theory appear in a few countries, such as Mexico, Croatia, Kazakhstan, Iran, Algeria, Indonesia, and Thailand; (b) the energy consumption has statistically positive and significant impacts on boosting the carbon emissions; (c) the negative effect of international trade emerges in the developing nations enjoying trade surpluses; and (d) fossil energy share poses a mixed impact. This paper reveals that the vast and inspiring contribution of developing countries to global carbon emission reduction should attract more international attention and assistance.

Today, about 10 million hectares of the world’s forest cover have been converted to other land uses. In Nigeria, there is an estimated increase of 8.75 million ha of cropland and decrease of about 1.71 million ha of forest cover between 1995 to 2020, indicating that Nigeria has been undergoing a wide range of land use and land cover changes. This paper analyses the changes in land use/cover in Ila Orangun, Southwestern, Nigeria from 1986 to 2018, with a view to providing adequate information on the pattern and trend of land use and land cover changes for proper monitoring and effective planning. The study utilized satellite images from Landsat 1986, 2002 and 2018. Remote sensing and Geographical Information System techniques as well as supervised image classification method were used to assess the magnitude of changes in the city over the study period. The results show that 26.36% of forest cover...

With the increase in technology, industrial activities and population, solid waste generation has consequently been increasing over the years. In this paper, the socio-economic factors that affect household solid waste generation in some selected wards in Ife Central Local Government Area were presented. The quantities of household solid waste generation were monitored continuously (weekly) for two months. The solid wastes collected were weighed using a weighing scale. A total of one hundred and fifty four (154) questionnaires were administered to selected households to elicit information on the socio-economic characteristics of the respondents. The data collected were analyzed statistically. The study revealed that gender, educational background and family size are important socio-economic factors affecting household solid waste generation. The highest overall mean weight of solid ...

This study aimed to determine the impact of different agricultural land uses on soil microbial biomass and also study the interrelationships between microbial biomass carbon (MBC, μgCg-1), Nitrogen (MBN, μgN g-1) and Phosphorus (MBP, μgC g-1) with the physicochemical characteristics of the soil. A total of 100 soil samples were taken from four different agricultural land uses viz., (cocoa plantation, grazed land, arable land and fallow land). Average MBC was 200.04 μgCg-1, 189.24 μgCg-1, 180.04 μgCg-1 and 129.18 μgCg-1; average MBN was 19.84 μgNg-1, 18.16 μgNg-1, 17.60 μgNg-1 and 12.74 μgNg-1 while the average MBP was 7.62 μgPg-1, 7.26 μgPg-1, 7.22 μgPg-1 and 6.40 μgPg-1 for cocoa plantation, grazed land, arable land and fallow land respectively. One-Way ANOVA showed a significant difference in microbial biomass C, N a...

We conducted a multifaceted rapid assessment to evaluate the conservation status of the grove eleven years after it was designated a World Heritage Site. We recorded a rich diversity, consisting of 2 rock types, 3 minerals, 88 plant species, 108 insect families and 4 mammal species. Our survey also enabled us document up to 40 cultural artifacts. However, the plants, small mammals and insects collected, in their role as indicator taxa, demonstrate that biodiversity decreases extending outward from the core area of the grove into the buffer and outside zones. In addition, the detection of heterotrophic bacteria and fungi from microbiological analyses in water samples of the Osun River which runs through the grove raises health concerns. Our findings lead us to recommend that efforts be stepped up to deter encroachment of the buffer and outside zones into the core area of the grove. Furthermore, careful repair of deteriorating cultural artifacts should be undertaken regularly, with the actions of visitors monitored adequately to prevent depletion of biodiversity and pollution of the environment.
