Environmental impact of trade sector growth: Evidence from the Mining Sub-Sector in Tanzania

Environmental changes across the globe have been growing at an alarming level that calls for appropriate channel to address the situation. Tanzania, in particular, has been experiencing dramatic climatic changes at different parts of the country due to ongoing environmental degradation. There has been growing changes in both seasonality and intensity of weather condition that range from temperature to precipitation context. This study has evaluated the roles played by performance of trade in mining sector to the environmental impediments in Tanzania, where rainfall distribution has been taken into consideration as a package of environmental variable. Correlation or prospective research design has been taken into practice to determine the relationship between mining export growth rates and rate of change of rainfall distribution. The results were intended to be the sufficient basis to scrutinize the degree of relationship between two variables under investigation. The study revealed the presence of weak positive relationship in the sense that no always the case for the two variables to have taken the same trend (either positive or negative). The set up weak relationship, therefore, thwarted further analysis of evaluating causality. Mining export performance has observed to take positive upward movement as opposed to rainfall distribution whose trend was absolutely unpredictable with sinusoid structure. However rainfall distributions were noticed to decline in long run thus calling for constant research and development efforts to find out newer and latest technologies and methodologies to reclaim the land for better environmental protection.
