Part II Community-Based Forest Management Program - ppmrn

SOUND IMPLEMENTATION AND MAINTENANCE STRATEGIES/ACTIVITIES
• The CSD implementation of the PWRS was not in accordance with
the land use plan defined in the Feasibility Study resulting in
increased estimated soil erosion from 303,455.92 tons/year to
390,898.39 tons/year. Moreover, inappropriate upland cultivation
which promotes soil erosion is widely practiced.
As disclosed in the following documents, PWRS project was designed
to prevent soil erosion as the site and watershed areas are generally
susceptible to soil erosion:

Provision
Soil erosion poses a serious threat to most of the present and
potential agricultural areas of the Province. Almost 110,000 ha
(13%) is already classified as moderately to severely eroded. Despite
the very serious threat soil erosion poses xxx it is not given adequate
attention. xxx As such, there is a need to promote indigenous and
introduced soil and water conservation technologies to combat the
linked problem of rainfall runoff/soil erosion. xxx
• The subproject aims to rehabilitate the watershed’s vegetative cover,
minimize soil erosion losses and improve the water yield and quality
of tributaries and major waterway of Pulangi and Tigua Rivers.
• Specifically, the subproject aims, among others, to introduce proper
farming techniques to minimize soil erosion.
• Estimated average loss of soil is placed at 80.55 tons/ha/year,
however, with the implementation of the subproject, the soil loss will
reduce to 51.62 tons/ha/year or a 36% reduction.
• Section 2.1 – Enhance the conservation, protection and
rehabilitation of watershed reservations to reduce soil erosion and
sedimentation, improve water yield and quality and promote
biological diversity.
• Section 4.1.4 – Promotion of land uses and practices that increase
productivity and conserve soil, water and other forest resources.
Thus, under the feasibility study (FS) for PWRS, agro-forestry and
other farming activities shall be confined only in moderate slopes to
prevent and minimize occurrence of soil erosion. It was proposed that
the PWRS development be undertaken as follows:
