Abstract
This paper presents the applications of Geoinformatics System (GIS) in three different
land-use planning (LUP) approaches. The participatory LUP (PLUP) which strongly
consider the local people perceptions for land utilizations, the guidelines for LUP by FAO
enhanced with multi-criteria evaluation (FAO-MCE), and the land-use planning and analysis
system (LUPAS) using interactive multiple-goal linear programming. The case study was
two villages in the coastal area of the Mekong Delta (MD), Vietnam. The land use of the
studied area is diverse, quickly shifting and strongly contrasting. The contrast is not only in
terms of resources but also in economic profitability and environmental sustainability. GIS
plays an important role in the successful of these three LUP approaches. In PLUP, GIS help
to integrate the acquired spatial and attribute data from farmer discussions and cross-section
walks, and to analyses the changes in not only biophysical, land cover changes but also
farmers¿ perception changes in land utilizations. The conflicts in resources uses, mainly
between agriculture and aquaculture, were also mapped and described. In FAO-MCE, a GIS
was used to combine biophysical and socio-economic characteristics for land evaluation. A
multi-criteria evaluation tool was developed to support the decision maker in trade-off
among different stakeholders¿ interests. In LUPAS, an optimization model was developed.
The model is linked with a GIS for data input and results presentation. With the optimization
model, the land use planners can explore different land use scenarios with different
objectives and constraints, both biophysically and socio-economically. The results of the
model are sets of land use option maps with their resources requirements, e.g. labor or
capital requirements, and their outputs, e.g. productions of shrimp, rice or total area of
forest. This information is very important for the decision-maker to select the most suitable
land use plan for the study area
