Soil degradation has become a crucial environmental problem in Sri Lanka, especially in the upcountry area, including the Nuwara Eliya district. Bogawantalawa South Grama Niladhari Division has been identified as a vulnerably area for soil degradation and environmental impacts. This division has shown a drastically increasing trend, due to unplanned human activities. The main objective of this study is to identify the environmental impacts of soil degradation in theĀ  Bogawantalawa South Grama Niladhari Division. This study followed quantitative and qualitative methods to collect data, applying purposive sampling techniques. 86 affected families as samples have been selected for questionnaire survey and field observations, while structured interviews and multiple discussions have been carried out to collect primary data. The data has been analyzed using MS-Excel and SPSS. According to the findings, there is a higher variability of environmental impacts, such as natural disasters (landslide and flood)-(31%), water pollution (24%), modified natural terrain (21%), decreased soil quality (19%) and soil organism (5%). The vulnerabilities have increased, due to gem mining (40%), vegetable cultivation (24%), tea cultivation (21%), and infrastructure development processes (15%). This study invites all stakeholders to participate in minimizing the environmental impacts of soil degradation, through an integrated approach. This study further suggests to promote environmental friendly gem mining activities by way of protecting the extracted soil, refilling the gem mining pits, prohibiting illegal and unregulated gem mining. Recycling polluted water, using organic fertilizers, finding hazardous areas through a hazardous map, and conserving them are other suggested measures to minimize the soil degradations of the area. Similarly, it is important to practice sustainable soil-conservation and farming methods, while ensuring strict implementation of existing soil conservation laws against illegal activities and providing frequent public awareness and education on environmental-friendly practices, among the public.
