WHY DESIGN THIS RESEARCH?
Top-down environmental planning process in upland districts in
Vietnam is not really effective
Environmental planning less takes into account the local
participation leading to the failed program or selecting expensive
measures
for instance Lo O (bamboo) tree plantation in A Luoi district (uplands)
of Vietnam is not feasible because the authority made themselves
without the consultation with local people
The aim is to design and implement an integrated framework for
environmental protection planning using participatory methods (nonICT source) in combination with GIS and RS (ICT – Source) while
taking into account the importance of rural livelihood improvement
through environmental planning process
RESEARCH QUESTIONS
• What is the situation
of soil erosion and
landslide in the study
area (uplands)?
• Can Non-ICT and ICT
sources combine to
support the
environmental
protection planning
model for livelihood?
LITERATURE REVIEW
• ICT source: Binary – based GIS modelling for suitability analysis
– Uses logical expressions to select map features from a
composite map or multiple grids. Output of binary model
is in binary format
• 1 – True for map features that satisfy the logical expression
• 0 – False for map features that do not
– In addition, several query and map analysis methods are used to
process the model such as select by them, geo-processing in GIS
software packages.

Grid model
LITERATURE REVIEW (cont..)
• Non-ICT source: Local knowledge can be integrated into the AHP
(Analytical Hierarchy Process) to make a participatory mapping and
planning.
Step 1: Development an AHP hierarchy by local people
Step 2: Next, the decision-maker expresses opinion regarding the relative
importance of the criteria.
Step 3: These preference scores after decision makers opinion
Step 4: The final step in the AHP process is to complete the synthesis in order
to obtain a vector of normalized unit-less weighted preference scores for
each of the three alternative sites.
METHODOLOGY
FINDINGS
CLIMATE CHANGE EVIDENCES FROM LOCAL
MEETINGS
 Rainy season period changes significantly.
 Wet season appears later than previous years
(2009 and 2010).
 Temperature variation between winter and
summer has been increasingly expanded and
more severe.
 The number of floods has increased every year.
Droughts tends to last longer than – many forest
fires (April to September).
 The scale of river bank erosion and landslide are
more severe due to floods and droughts.

Planning for erosion and landslide protection:
Integration of ICT and Non-ICT sources
• Step 1: Participatory GIS mapping of soil erosion and landslide
Step 2: Selecting the community-based option for soil
erosion and landslide
Lo O bamboo is local people’s choice
Step 3: Identity criteria for Lo O bamboo plantation planning
Step 4: Building Binary-based GIS model and participatory
planning
Step 5: Check the suitability of Lo O bamboo
plantation map
Step 6: Make the final soil erosion and landslide planning
• A report of soil erosion and
landslide
planning
was
completed to share with local
authority and farmers.
• Local people was chosen to
plant Lo O bamboo according
to the planning
• The plantation of Lo O Bamboo
was organized in different local
community group to manage
Lo O bamboos were planted in selected
areas to prevent river bank erosion and
landslide and to protect cassava areas
CONCLUSIONS
• Participatory GIS mapping and planning is an effective way to
make environmental planning in order to adapt with changing
environment in Vietnam, especially for rural areas.
• Local knowledge is very crucial and useful to achieve a feasible
environmental planning.
• GIS supports well to ensure the accuracy of spatial distribution
and modeling environmental phenomenon.
• However, the model needs higher quality data to have better
modeling and a community-based Lo O bamboo plantation
model for long-term environmental planning management
should be formulated during the planning process.

sources for environmental planning and climate
change adaptation in Central Vietnam” for
publishing a chapter of book.
