The socio-ecological and political properties of rural and urban landscapes have been argued to produce the differentials in rural-urban health. However, the mechanism of the COVID-19 pattern in this socio-political-ecological perspective has not been understood in Africa. The study used spatial techniques to explore the pattern of urbanization-COVID-19 nexus in Nigeria. It has been argued that three elements (demographic dynamics, infrastructure or governance) typify the socio-political-ecological landscape of urban places. They shape the spread of infectious diseases. We explored the extent to which these factors predict the COVID-19 pattern in Nigeria. The study used data from Nigeria’s Centre for Diseases Control and the National Bureau of Statistics. The results indicate that more urban states in Nigeria tend to have higher COVID-19 cases than rural states. The COVID-19 pattern is best predicted by population dynamics more than other elements. The result indicates demographic attributes are more critical to surges in COVID-19 cases in Nigeria. Places with higher populations and densities will tend to have more spread of the virus than places with lesser populations and densities. Therefore, in a future outbreak, places of high densities should be given more attention to prevent further spread.

This paper looks at the terrain and landforms in Anambra State. The research used both primary and secondary data. Primary data used are measurements and direct field observations. Secondary data are from Satellite imageries of the State obtained and analyzed using ArcGIS to show the variations in the terrain and landforms of the study area, and other literature. The geology, topography and soil types of the State were identified, analyzed and mapped. The result shows among other things the relationship between soil type and settlement vis-à-vis population. The slope analysis was also carried out in order to identify areas with steep slopes that limit accessibility and other economic activities. The paper concludes that there is strong influence of the physical environment particularly, the geomorphological factor in determining the spatial pattern of socio-economic activities and development in Anambra State. A disproportionately high percentage of population (71.98%) as well as developmental activities and structures are found on the higher grounds, on the smaller sand – sandstone formations covering 36.42% of the State, leaving a very small percentage of population (28.02%) as well also as developmental activities and structures on the larger flood and other low plains covering 63.58% of the area. These disparities in population distribution as a result of gromorphological factors raises the issues of the need for the government and people of the State to employ new developmental ideas in the area of science and technology to overcome the limitations on the lower surfaces in other to attract settlers and balance population distribution in the State.

Soil erosion in southeastern Nigeria has a high devastating tendency which created a natural geologic hazard is causing loss of arable farm lands, destroying properties and other social infrastructures like pipelines, roads, bridges, over head and underground cables that are being exposed and or washed away by deep gully erosions. Investigations into the underlying factors of soil susceptibility to soil erosion in southeastern Nigeria led to this work. The study areas are the twenty six Local Government Areas within the centre of the zone which are Anaocha, Orumba North, Aguata, Nnewi South and Orumba South in Anambra State; Umunneochi, Bende, Ohafia, Arochukwu and Isuikwuato in Abia State; Afikpo North, Afikpo South, Ivo, Ohaozara and Onicha in Ebonyi State; Aninri, Oji River, Ezeagu, Udi and Awgu in Enugu State, and Idea to North, Idea to South, Okigwe, Orlu, and Orsu in Imo State. The dataset for this research work are from secondary and primary sources. Secondary Data were extracted from other journal publications among others, while primary data were in the form of measurement during field visit, photographs and geophysical soil survey and verification. Descriptive Statistics, Student t-test and Chi-square test analysis were used. The result shows that the soils across the study area generally are predominantly sandy with a mean of fine sand at 28.22% and coarse sand at 43.40%, while the mean of clay and silt are very low, 17.82% and 10.56% respectively. The study concludes that high sand content in the composition of soil in the study area is responsible for high rate of soil erosion in the area and therefore recommends a policy framework from the government of Nigeria that will encourage a paradigm shift from roots and tubers crop production that exposes the soil, to orchard plantation.
