EVALUATING THE ENVIRONMENTAL IMPACTS OF GARAGES IN CAMEROON USING AN IMPACT MATRIX FRAMEWORK: A CASE

This research focuses on the environmental implications of garages in the Yaoundé II subdivision (Yaoundé, Cameroon). Several data from observations and surveys were employed to achieve this goal. The surveys were conducted in 49 garages, accounting for 73 percent of the total garages counted by the Yaoundé II municipality in March 2015. The impacts were determined based on on-the-ground information about garage components and existing environmental sensitivity. The matrix approach of Leopold is used to identify the influence on various environmental components. We also used Martin Fecteau's Matrix to determine the magnitude of the effects. The diverse activities of garages, which are divided into three categories (mechanical, electrical, and sheetmetal), have both harmful and good effects on the environment. Air pollution, ozone layer depletion, soil pollution, and mechanics' health are all severe negative consequences. To reduce these effects, the proposed methods include limiting gaseous and particle emissions, prohibiting trash disposal on the ground, requiring the use of protective equipment, and adhering to safety regulations. Furthermore, we highlighted the positive effects, which included: increased municipal and state revenues through the payment of various taxes, development of the local economy, and prospects for direct and indirect employment. To optimise these effects, it is vital to improve the mechanics' working conditions with the help of the government.
