Abstract

 

The analysis of livelihood indicators contributes to identifying the differences of the livelihood characteristics of farmers in a particular region. However, the livelihood survey is usually influenced by several factors (i.e. cost, labor, and distance) that leads to a challenge of addressing all aspects in a survey of a studied area. Spatial statistical methods, particularly the interpolation method, allows the computation of values at a non-measured position through identified values and its surrounding. This study applied the Inverse Distance Weighting method (IDW) to interpolate and determine the Livelihood Asset Index (LAI) within the investigated area of three districts including Tam Nong, Thap Muoi and Tan Hong. The results showed that there was an unequal distribution of capital resources and livelihood assets index among communes as well as districts in the area. Additionally, the IDW method seems to be a powerful tool in spatial statistics with high accuracy. The results of this study can also be used to assess the livelihood status, contributing to creating the connections among regions in the area for sustainable development.
