•
indirect impacts in an area due to changes in water quality or quantity;
or
•
enhanced protection and management of protected lands as a result of
financial support from the project.
With respect to the slurry pipeline, stakeholders have expressed particular
concern with the effect of the pipeline on the Torotorofotsy Ramsar site and the
Mantadia-Zahamena forest corridor (Volume A, Section 6). Various alternatives
to this pipeline routing have been considered, as discussed in the analysis of
alternatives (Volume C, Section 1). The route through the Ramsar site now takes
advantage of a corridor of existing disturbance and is the believed best option
from the perspective of social and environmental effects and pipeline
engineering.
Linkages of effects on protected areas to other components are shown in a
linkage diagram (Volume H, Appendix 9). The key question for protected areas
is:
Key Question PR-1
What Effects, Direct and Indirect, Will the Slurry
Pipeline Have on Protected Areas?

Impact Assessment
The slurry pipeline footprint overlaps with the Torotorofotsy Ramsar site and the
Mantadia-Zahamena Corridor. Based on
Arrêté
20-021, a service corridor for
both railway and slurry pipeline will not be put under conservation status.
However, the pipeline has the potential to fragment the Torotorofotsy Ramsar
site and the Mantadia-Zahamena Corridor. Also sediment from disturbed areas
may affect streams near the pipeline right of way (RoW).
The project will contribute to additional RoW reclamation (to zonal forest)
within the Torotorofotsy Ramsar site and Mantadia-Zahamena corridor with
appropriate native species, and will seek to contribute to management plans for
the Ramsar site within the regional planning process, as appropriate.
4.5.5.1 Assessment Methods
The assessment of effects on protected areas is based on:
•
a physical analysis of extent of protected areas that the slurry pipeline
footprint will overlap in the LSA; and
