Environmental Assessment

Prediction Confidence
The prediction confidence for this assessment is moderate to high. Uncertainties
are associated with the effectiveness of mitigation in controlling erosion and
sediment, the effectiveness of revegetation of key sections of the RoW with
native species, and the degree to which protected areas will be affected by
fragmentation in the short term.
4.5.5.6 Monitoring
During construction, erosion control will be maintained and monitored to
minimize downstream sedimentation issues. The vegetation community (a key
component of the ecological system) will be monitored as described in Volumes
B and C, Section 4.1.

Conclusions
Low environmental consequences will result for the Torotorofotsy Ramsar site
and Mantadia–Zahamena corridor during the construction and operations phases
of the project, due to the clearing of land and increased risk of sedimentation of
water bodies and watercourses.
Impacts following closure are expected to be of negligible consequence, and fully
mitigated through reclamation.
Positive impacts are anticipated through the project’s participation in
conservation measures of key sections within the Mantadia-Zahamena corridor
and the Torotorofotsy Ramsar site.
The impacts resulting from development of the slurry pipeline are not expected to
adversely affect tourism potential for protected areas in the RSA.
