It is with the quantitative research approach and by capturing the views of the environmentalists, researchers and specialists in environmental issues and management in Mbeya City the facts were revealed. The facts were collected primarily through structured questionnaires and secondarily by reviewing literatures. The collected and processed data were analyzed by using the rotated component matrix, ordinary least squares and ANOVA in which the results were that the market-based method was more effective than command-and-control method with F- value = 10 at a significance level of 0.01.
