Application of geo-informatics and models for land use change prediction in Nan province
Abstract:
This study aims to apply Geo-Informatics integrated with CA_Markov and regression
models to classify land use pattern, land use changes from 1990 to 2005 and predict land use
change for the next 10 years in Nan province.
It was found that land use change from the year 1990 to 2005 was categorized by a
high reduction of mixed deciduous forests and high increase of field crops or upland crops.
Meanwhile, the land use prediction through of CA_Markov and Regression Models for the
year 2010 indicated changes in the same direction as the changes from the year 1990 to 2005.
The accuracy of land use prediction using CA_Markov was manipulated based upon the land
use classification in 2005. It showed an accuracy of 82.12% (Kappa Index 0.78%). The
comparison of land use prediction using CA Markov and Regression Models indicated the
overall similarity as 89.81% (Kappa Index of 0.87%). The land use maps classified in the year
1990, 2000, 2005, and 2010 were then compared with the land suitability maps done by the
Land Development Department. It was found that economic crops mostly grown in Nan
province including paddy fields, and perennial or fruits trees were cultivated within the
moderately suitable area. Meanwhile, field crops or upland crops have been cultivated within
the non suitable area
