Abstract
The study employed four (400) structured questionnaires and Geographical information system (GIS) was also used. Photographing, oral interview, and air pollution observation and water bodies site visit within the metropolis was conducted. The Built up area changes study covers 35 years (1984 to 2019) and it employed Remote sensing technology and the Landsat images of 1984, 1998 together with 2019. Land use were classified into four major categories as (a) Farm land / open fields (b) Trans cape / Irrigated field ( c) Built up areas and (d) Water bodies but for this study, built up area was only considered. E. View 8 version was adopted for the analysis. Descriptive statistics was employed for the interpretations with the aids of photographs.The study uncovers that built up areas speedy growth of 10.030 hectare which represent 23.59% between 1984 to 1998 was identified. It shows significant growth of 6828 hectares within 1998-2019 which represent 5.18%. The study also depicts annual urban growth is higher between 1984 and 1998 as 1.67% but annual growth between 1998 to 2019 is 0.25%.The resultindicates that there is positive correlation between dependent variable (DV, Environmental Impact and explanatory variables (BEN), High Population Growth (HPG), Site Clearance for Housing (SCH), High Rate of Urbanization (HRU), Housing Congestion (CH), Building Density and Environment (BDE), Buildings and Vegetation Energy Resources (BVER) and Zoning Regulation(ZR).It also unveiled that Hydro Electric Power is the major types of power sources 93% then followed by solar source with 7% responses.

Density response revealed that 54% of the dwellerslived in high density, 29% stayed in medium density and 17% reside in low density. Urbanization challenges uncovers thatvegetation cover is rapidly decreasing in Kano has total of 92% supportive respondent responses. In addition, responses on housing sector is rapidly increasing is strongly agreed was supported by 90%. On the other, perception of population is rapidly growing maintained responses of 90% but temperature increases in Kano records 53% responses. Generators usage promotes air pollution has 100% responses. Recommendation was drawn from the identified issues.
