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 (non-ICT 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.
Vector model Grid model
• 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
FINDINGSCLIMATE 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.
at study area in 2010
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.
