Abstract:
Soil erosion, deforestation, and pollution of water and soil often occur as a result of gem
mmmg. These impacts are relatively simple, easy to control, and nontoxic.
Deforestation results from clearing land to mine; erosion and epidemic results
from abandoned mining pits; and pollution is due mainly to washing schist near streams
and scattering debris from the schist into soils. Implementation Df policies to control
these problems is needed to control the degradation in Sri Lanka due to gem mining. The
number of informal (unregistered) mines, pressure from unionized gem miners, lack of
capital in the small mines, and a lack of cohesion in gem mining policies are the threat for
controlling the environmental degradation due gem mining. Environmental agencies
have begun to crack down on enforcing clean-up policies. The creation of a series of
common washing sites for gem miners indicates that municipal government agencies are
making some investments toward reducing pollution due to gem production. An
environmental NGO should involve in environmental education for small miners and
others in the gem production chain.
