Urban growth and its challenges in Kano metropolis cases of CO and NO2

Abstract

The aim of the study is to assess the air pollutants emission with reference to carbon monoxides and Nitrogen Oxides with the view to make urban and regional planning recommendation towards low carbon society. Primary data was gathered from field with the aid of gas sensing device (Gas Sensor By Crown Cone) Outdoor carbon monoxides and Nitrogen Oxides was sensed in four (4) selected local government authorities namely Kano Municipal, Fagge, Nasarawo and Tarauni based on the land uses interactions and 4 major road intersections (junctions) in each local government reading stations was sensed each in a specific days. Monday and Fridays was selected as the busiest day. Friday was used for Kano Municipal and Nassarawo while Fagee and Tarauni Monday was employed the. The study also utilized secondary data obtained from available sources of majorly related journals. The result was tabulated for comparison. The result depict that the study unveiled that, Tarauni local government has the highest average value of carbon monoxides of 21Ppm. The study also indicates that on the other hand, Tarauni local government demonstrates the highest records of Nitrogen Oxides (NO2). This is due to its high volume of traffic. Nassarawa and Fagge local governments relatively portrays very close records of sensed carbon monoxides with 16Ppm and 15Ppm. The result further indicates that Kano Municipal local government maintain the least records of both Carbon monoxides and Nitrogen Oxides of 13Ppm and 00.4. This is due to the facts, the traditional city has less vehicular movements because of its connectivity challenges with the walled city. This therefore affects its rate of emission. Urban plaining towards Low carbon society is to strongly recommend so as to safe guard the environment in sustainable manner. This could be achieved through in-depth study of environmental implications of urban growth within the study area.
