It further sought to find out the driving forces and implications of oil spillage on vegetation, livelihoods and other key parameters. The study employed geospatial techniques and a secondary source of data to achieve the objectives set out in this study. The Global Moran I statistical tool was used to determine the spatial autocorrelation based on feature locations and attribute values. We observed built-up areas, bare land, and less dense vegetation had an overall increment of 1975.98 km2, 1370 km2 and 23805 km2, respectively. Dense vegetation had declension of 22058.33 km2 over the past five decades. Findings depict a declining trend in Normalized Difference Vegetation Index, attributed to oil spillage as the key contributory factor. Occasioned by anthropogenic activities, the driving forces were traced to attacks on oil pipelines during conflicts and i...

This work uses bias-adjusted Coupled Model Intercomparison Project Phase six (CMIP6) model datasets to investigate the future changes in temperature extremes over Mediterranean (MED) and Sahara (SAH) regions. The mid- (2041–2070) and far-future (2071–2100) are studied under two Shared Socioeconomic Pathways: SSP2-4.5 and SSP5-8.5 scenarios. Quantile mapping function greatly improved the performance of CMIP6 by reducing the notable biases to match the distribution of observation data, the Climate Prediction Center (CPC). Results show persistent significant warming throughout the 21st century, increasing with the increase in radiative forcing. The MED will record a higher increase in temperature extremes as compared to SAH. The warming is supported by the projected reduction in cold days (TX10p) and cold nights (TN10p), with the reduction in the number of cold nights exceeding co...

Literature were reviewed on existing traditional approaches provided by PV module manufacturers, solar energy institutional boards as well as the related works done by researchers. An artificial intelligence approach to the maintenance of Solar PV modules was proposed. The approach is to eliminate huge maintenance line during maintenance, reduce accidents during maintenance and reduce work hours during maintenance. A theoretical prototype of the robotic control system was studied. The system is designed to have abilities to initiate maintenance process on condition of timing and environmental factors. A block diagram consisting of mechatronic devices, electronic sensors and timing circuits were used. The system detects targets by pattern, feature, and colour of the solar photovoltaic modules in array. The proximity technology used was the inductive type that detects magnetic loss due to eddy currents that are generated on a conductive surface by an external magnetic field.

In this study, we investigated the effect of two soil amendments, namely poultry manure and compost, on soil parameters and their influence on maize growth performance. The experiment was conducted at the nursery site at the University of Energy and Natural Resources where organic amendments were applied to the soil at different application rate compost (10 t/ha and 5 t/h) and poultry (10 t/ha and 5 t/h, respectively). The results show that organic amendments increased the NPK content of the soil. Plant growth parameters are also increased by the application of the organic amendment. There was no significant improvement in plant height, plant girth, and the number of leaves with the application of b...

The study ascertains local drivers of land-use cover change in Southwestern Ghana using a mixed-method approach. The approach aided in identifying key land-use drivers, using different research strategies for comparisons through confidence level analysis and Analytic Hierarchy Process. We used expert interviews, existing literature and geostatistical tools to ascertain the driving forces triggering such unprecedented changes. Landsat imagery 5 MSS, 4 and 5 TM, 7 ETM+ and 8 OLI/TIRS were acquired from the United States Geological Survey’s website. Land use analysis revealed a decline in forests (-334.8 km2yr−1.) and areas covered by waterbodies (-4.79 km2yr−1.). A remarkable increase in built-up (+137.93 km2yr−1.) and farmlands/shrubs (+131.97 km2yr−1.) areas were also observed. Th...

Efficient policy frameworks coupled with prudent urban management are deemed as reasonable balance to environmental benefits. Research reveals urban areas in Ghana are confronted with the rapid loss of natural resources as urbanization increases. This synthesis report examines the ramifications of major issues faced by the Greater Accra region based on existing literature by (i) highlighting contemporary environmental problems in Accra (ii) probing into human-induced and natural factors that alterate environmental harmony in the study area (iii) discussing measures on safeguarding the environment through a sustainable approach in Accra, and (iv) presenting policy implications of environmental problems in Accra. Findings indicated urbanization, poverty and inappropriate urban planning systems influence environmental degradation in the study domain. Anthropogenic activities such as pollution and natural hazards like: flooding, drought and windstorms events have altered the physical properties of Accra. This paper reveals the assumption and execution of values to safeguard environmental resources in the Greater Accra Metropolitan Area.

The present study sought to assess the impacts of climate hazards on coastal livelihoods, specifically in Ningo-Prampram district in the Greater Accra region, Ghana. The research uses participatory rural appraisal (PRA) and the analytic hierarchical process (AHP) tools to ascertain the major climatic and non-climatic events, along with their impacts. Findings revealed coastal inundation and submersion were the major stressors that triggered dysfunctions of residents' livelihoods. Impacts from these stressors constituted decline in household income, collapse of buildings along the beach, and saltwater intrusion rendering farmlands unproductive causing reduced crop yield. Cabbage and chilli farms that are no longer arable have been sold to estate developers. Sea level rise has resulted in the submersion of coastal lands (1 km-2 km land residual inland). Residents undertake temporal evacuations with financial assistance from local financial institutions. Minor interventions like the growing of mangroves and coconut trees have been initiated to somewhat serve as defence mechanisms. However, residents have continuously harvested these plants along the coast with no plans for afforestation, re-afforestation and other sea defence mechanisms. This leaves the area highly vulnerable, hence, the present study attempted to bridge this paucity of knowledge to inform the decision of relevant stakeholders in prioritizing climate-related issues that affect livelihoods in the area.

Findings depict a declining trend in Normalized Difference Vegetation Index, attributed to oil spillage as the key contributory factor. Occasioned by anthropogenic activities, the driving forces were traced to attacks on oil pipelines during conflicts and illegal means of creating leakages to siphon crude oil for sale. To achieve sustainability in oil spill management in the Delta, the study recommends further research to ascertain the cost of losses incurred apply geospatial techniques to monitor and predict environmental changes that inform decisions of key actors.

Understanding direct and indirect factors that influence land use cover change (LUCC) is essential for modelling future LUCC in developing countries. The study analyses local drivers of LUCC in Southwestern Ghana using the mixed-method approach. The approach aided in identifying key drivers of LUCC, using different research strategies for comparisons through confidence level analysis and Analytic Hierarchy Process (AHP). We used expert interviews, literature review and geostatistical tools to ascertain causative factors triggering such unprecedented changes. Geospatial analysis depicted a decline in forests (-1.65 km2yr-1.) and areas covered by water bodies (-0.55 km2yr-1.). A remarkable increase in built-up (+25.77 km2yr-1.) and farmlands/shrubs (+7.4km2yr-1.) areas were also observed. Population growth, expansion of settlements and infrastructure, coupled with agricultural expansion are at the centre of the LUCC-environment nexus, based on the confidence level table. A steady increase in surface temperature can be attributed to the unprecedented LUCC over the past 50 years. Socioeconomic development in Southwestern Ghana is fuelling interest in the relation between LUCC and environmental change. Biophysical, cultural and technological factors are also considered key drivers despite the "medium-to-very low confidence" in results generated. They could potentially impact climate-sensitive sectors that significantly modify land-use systems from the pessimists and optimist's perspective. We, therefore, propose further analyses of LUCC drivers with medium to very low confidence levels.
