Negative importance of mining in Uganda includes;
- Mineral extraction machines and process emit fumes which pollute the atmospheric air. This explains why Kasese, Hima and Tororo experience a dirty contaminated air.
- Mining disturbs the soil structure by digging it which destroy the land. Open cast pits normally encourage the occurrence of severe soil erosion as it is in Tororo.
- The soil erosion which has occurred due to mining activities has led to siltation of river valleys causing floods which has resulted into water borne diseases like bilharzias, typhoid and cholera.
- The open cast pits left behind and filled with water have become breeding grounds for dangerous pests like mosquitoes which cause malaria and this has been witnessed in Rukungiri gold mines.
- Clay and sand mining mainly in Kajjansi has reclaimed wetlands which has endangered animals which have their habitats in swampy areas.
- During the establishment of mines, large portions of forests have been cleared. It is estimated that Kirembe mines cleared a lot of forest cover on the foot of Mt. Rwenzoi.
- It has increased on population within the mining areas which has led to urbanization of such regions. However the population pressure in such areas has got negative effects like robbery and theft, slum growth and prostitution, increasing cost of living and yet there high rates of unemployment
