Abstract
Land use Planning and Management is considered a very complex issue since it is usually solved by the multisectoral-interdisciplinary hiarachy decomposition approaches. In general, land use planning indicates the consideration of water, social, socio-economic, economic and environmental issues. In which socioeconomic and insfrastructure data are used and delineated for maps manipulation in land evaluation and land use planning. The study aims at merging the GIS and socioeconomic data approaches for the land use planning. A case study of about 2,604 ha of TanPhuThanh village, ChauThanh district, Cantho province has been selected to be stimulated through the merging of GIS and socioeconomic data for the sake of land use planning. Different proposed suitable and use types (LUT) zones (LUT1 : Winter-Summer rice + Summer Autumn rice + Fish, LUT2 : Winter-Summer rice - SA rice – Autumn-Winter rice + Fish, LUT3 : Winter-Summer rice-SSupland crops- Autumn-Winter rice + Fish, LUT4 : Winter-Summer Upland crops- Spring-Summer upland crops - Autumn-Winter rice + Fish, LUT5 : Intensive vegetable, LUT6 : Fruit trees + Fish) have been proposed. Through the merging of GIS, socioeconomic and infrastructure have been run and evaluated on two forms of evaluation: physical and socio-infrastructure evaluations. It has been found that this merging is resulting a very powerful and robust tool for evaluation of different proposed plans on integrated levels. The merging of GIS and infrastructure conditions has really facilitated the decision making process for such type of problems. It is recommended to use such methodology in the integrated land use planning and management in that including physical and socio-economic conditions. The socio-economic factors used in this study so-called “infrastrure requirements of land use types” mainly consist of the distances from farmers’house to the main road, rivers (for transportation); maket, factory (for accesibility to the maket and processing) and to the seed supply and agricultural materials. The results showed that those factors affected to the suitability of land use types in term of infrastructure improvement. LUT5 (Intensive vegetable) has largest area that give high suitability of land under those conditions. The reason is that most of LUT5 located mainly along the river and main road. |
