Mining can negatively impact biodiversity through direct and indirect effects. [1] Direct effects include water and air pollution, habitat and species loss from the mine site. [2] Indirect effects occur across wider landscapes, such as downstream water pollution and loss of ecosystem services. [3] A proposed mining project in the Philippines overlaps critical watersheds and forests, threatening over 20,000 hectares of farmland and increasing poverty for forest-dependent communities. Rehabilitation may require billions in costs while damage to biodiversity could cause local species extinctions.

10. Impacts
Mining has the potential
to affect biodiversity
throughout the life cycle
g y
of a project, both directly
(at the mine site) and
indirectly (across a wider
landscape).
11. Direct impacts
• Water loss
and pollution
• Air pollution
• Species and
Habitat loss
• Oth
Other
services
12. Water loss and
pollution
ll ti
• Altered hydrological and
hydrogeological regimes (e.g.
decrease of water level)
• Increased heavy metals, acidity or
pollution
• Increased turbidity (i.e.
suspended solids)
• Risk of groundwater
contamination
13. Air
Ai pollution
ll ti
• Increased ambient
particulates (i.e. dust)
• Increased ambient sulphur
dioxide (SO2)
• Increased ambient oxides of
nitrogen (NOX)
• Increased ambient heavy
metals
14. Species and Habitat
p
loss
• Loss of ecosystems,
habitats and functions
• Loss of endemic and/or
threatened species
• Loss of important plant
p p
species with potential to
cure other known
illness/disease (e.g.
AIDS, cancer)
15. Impacts on
Service values
S i l
• Loss of access to timber and
NTFPs (e.g. medicinal plants,
fuelwood, etc.)
• Loss of access to grazing for
livestock
•IImpaired ecosystem services

21. Issue: Rehabilitation and restoration activities to atleast

with local extinctions possible.
22. “Not only have the oil, gas and mining industries
not helped the poorest in developing countries
countries,
they have often made them worse off. Scores of
recent academic studies and many of bank’s
own studies confirmed our fi di
t di fi d findings th t
that
countries which rely primarily on extractive
industries tend to have higher levels of poverty,
child morbidity and mortality, civil war,
corruption and totalitarianism than those with
more di
diversified economies.”
