Give two relevant examples of impact studies that could be conducted in our country ( south africa )

Following are two examples of impact studies that could be conducted in South Africa:

I) Effect of deforestation

II) Effect of increased vehicular pollution.

Explanation:

The country of South Africa once had a large forest cover which has now been cut down to only 7.6% of the total land area of the country. Also, after the end of apartheid, the country has seen a surge in the standard of living of the people resulting in the increased number of vehicles on roads.

This has certainly increased vehicular pollution in the country. The impacts of these two events can be studied in South Africa through various impact studies.
