Impact related to human activities
� The forests are constantly destroyed by anthropogenous activities like agriculture,
timber trees exploitation and the trade of charcoal, principal activity in the
country.
9.3 Mitigation Measures
� Clearing of vegetation can not be avoided at the areas specified for project
structures, but damage to the natural vegetation should be minimized. It is
recommended to use material (borrow areas) inside of the future reservoir and
dump unused, uncontaminated material (excavation material) in the future
reservoir (dumping areas). Keep additional sites as small as possible.
� The useful wood in the future reservoir area should be made available to the local
population.
� Local population should be advised to use during construction period, timber in
the future reservoir area for charcoal production. The full supply level should be
market in the field so that the people are aware where they should go for
harvesting, this would reduce the pressure on the surrounding forest for this period
and it would already clear parts of the reservoir area.
� The clearing of forest should be monitored by the Forest Development Agency.
� Do not disturb vegetation especially trees at the riverbank downstream of the
construction site.
� Do not use any herbicides for vegetation clearing (manual clearing rather than
herbicides).
� Any illegal logging of the work force must be forbidden.
� To counterbalance increasing pressure on forests due to the loss of trees growing
in the reservoir area and presently used for charcoal production, it is
recommended to carry out a plantation program of fast growing tree species which
are suitable for charcoal production, as e.g. Anisophyllea meniaudi, Nauclea
pobeguini and Uapaca heudelottii; other suitable species might be available for
this purpose. This activity should be developed as a community based program,
developed, managed and used by the local population, with support of the
Forestry Development Agency.
If the St. Paul River Cascade should be implemented (see Chapter 28), it would then be
advisable to develop a watershed management plan for the entire cascade; to the extent
possible, this should also include the part of the river basin located in Guinea. The main
aims of this plan would be to reduce erosion in the catchment area of the dams, and thus
to reduce siltation of the reservoirs.
