SCIENTIFIC AND TECHNICAL
STUDIES
To fill data
gaps needed in defining priorities for a management plan for the
Talomo-Lipadas Watershed (TLW), PCEEM-Davao Foundation, Inc. funded
scientific studies for the purpose of getting baseline information.
The following are studies conducted:
a. Biological
Water Quality Assessment of the Talomo and Lipadas Rivers (UPMin-ADDU,
2002). The assessment was through direct observation
of the living forms that were found in the rivers in the duration
of the study.
b. Bird
Communities as a Measure of Ecosystem Health in the Talomo-Lipadas
Watershed (Philippine Eagle Foundation-UP Min, 2003). It
aims to establish the baseline data on birds in the area; develop
and test a protocol for community-based monitoring of birds and;
train local stakeholders on bird
c. Coastal
and Marine Environment Monitoring and Conservation Project in Talomo
Bay, Davao City (ADDU-USEP, 2002). Focused on the status
of the shallow marine communities in Talomo Bay, the key indices
were siltation, mangrove, seagrass, coral reefs, shore activities,
fish and water quality.
d. Protocol
Development and Testing for Pesticide Monitoring (ADDU-FPA-BPI,
2002). It involved monitoring the movement of certain target
pesticides from two identified sampling sites within the watershed.
e. Talomo-Lipadas
Watershed Aquifer Characterization Study: 3-D Aquifer Model (Proulx,
2002). This was undertaken to have a 3-D visual “picture”
of the extent and thickness of the aquifer.
f. Terrain
Classification and Analysis of the Talomo-Lipadas Watershed Area
(MGB, 2001). In an effort to understand better the geophysical
environment of the TLW areas, a Terrain Analysis and Classification
of the TLW Areas was undertaken and completed in 2001. It recognized,
classified, mapped, and characterized at least seventeen (17) terrain
mapping units (TMU); as such the different active geomorphic processes
and the related geologic hazards were identified.
g. The
Physicochemical and Coliform Analyses of the Talomo, Lipadas and
Bago Aplaya Rivers (ADDU-DCWD-EMB, 2002). In this study,
the qualities of the rivers were determined through the monitoring
of certain physico-chemical parameters which established a baseline
on other parameters not previously covered by the DENR-XI and which
could be of great use in future water development and other studies.
h. Clarification
of the Zoning Ordinance at the Barangay Level. With land
use conflicts in the watershed areas and confusion on the application
of the city’s zoning ordinance, a training was conducted for
four pilot sites – Calinan, Dumoy (urban barangays), Catalunan
Pequeno and Malagos (rural barangays). The training improved the
understanding of barangay officials about the Zoning Ordinance and
emphasized the role of the Barangays in approving and enforcing
it.
i. IP
Community and Cultural Mapping. To enjoin the active
engagement of the IPs in natural resource management (NRM) as a
major stakeholder in the watersheds, a census was conducted of over
2000 households found in and above a 500 m elevation, covering 19
barangays to provide the primary data. Cultural mapping through
Participatory Rural Appraisal (PRA) provided a description of the
patterns of subsistence and livelihood of the indigenous people,
leadership and governance, and relationship with the environment.
A rapid needs assessment and problem identification was also done
in order that an intervention could be developed to address their
needs.
