Item An Assessment of Mining Activities Impact on Vegetation in Bukuru Jos Plateau State Nigeria Using Normalized Differential Vegetation Index (NDVI)(Journal of Sustainable Developmen,, 2011) Musa, Haruna D.; Jiya, Solomon NThe study area has a pathetic and deplorable condition of landuse/ landcover. The vegetal cover in the area has to be removed from the activities of tin mining which consequently resulted into adverse environmental effect such as erosion. Different forms of human induced stress such as tin mining and heavy rainfall have severely degraded soils on the Jos Plateau. Such degradation problems are also caused by deforestation, inappropriate farming system, bush burning and over-grazing which are hostile to the environment. The impact of tin mining has greatly affected the natural ecology of the study area Bukuru. Micro and macro organisms and plants have been stripped off their natural habitat due to tin mining activities. This paper therefore, assesses the mining activities impact on the vegetation in Bukuru area of Jos plateau in Nigeria. Normalized Differential Vegetation Index (NDVI) techniques was adopted to Maps effect of tin mining on the vegetation for the period between 1975 and 2007 using LandSat satellite data. The result of the differential vegetation index analysis reveals a decline in vegetated surfaces in 1986 ranging from 0.04 to 0.58 indicating 0.05 and continuous loss in vegetation over the study area in 2007 (vegetated surface decrease by 0.08 between 1986 and 2007). The decrease in vegetated surface is due to intensive mining and cultivation.Item Climate Change, Development and the Cities; Perception of the Residents of Minna, Niger State(Centre for Human Settlement and Urban Development Journal(CHSUD Journal), 2013) Dalil Musa; Musa, Haruna D.The level of an individual or communal understanding of climate change would engender any consequential response to planning activities. The assessment of urban residence perception of climate change issues in Minna town was measured based on a field survey conducted using structured questionnaires. A total of 2000 structured questionnaires were administered using systematic random sampling techniques. That’s 80 questionnaires, each was assigned to 25 existing wards covering the entire study area. The result of the field survey analysis reveals that 79.2% of the respondents are aware of changes in the general weather conditions of their environment, but attributed it to an increase in temperature or natural changes(46.4%). The result also shows that 816 of the respondents, representing 81.6%, could not directly link urban planning within the environment with climate change. This research has concluded that though people are aware of the changes in the climate conditions in their environment, the majority of people felt that emissions from vehicles, generators, etc., could not contribute to climate change, but merely cause environmental pollution. The reasons advanced by most of the respondents were that carbon monoxide emitted from cooking stoves and automobiles is too insignificant to have any negative effect on the global climate.
