A randomly selected sample of 14 villages  in t he area was studied and analysed .  It was found, based on t he type of crops cultivated and  market values, t hat three types of farming systems exists in the  area viz. Low-value Cash Cropping system, Medium-value Cash  Cropping system and High-value Cash Cropping system . They  differed from each other socio-economic, agronomic and land type  characteristics . It was also evident that crop yields varied  significantly among villages. As the terrain in the area consists  of steeply sloping lands, erosion problems were severe and low  soil fertility levels had led declining yields for maize and  ginger crops which were low input enterprises. Farm input use for  different crops a nd Gross Margi n analysis is out lined in detail.  Vegetables were found to be more profitable in the area, followed  by mulberry. The need for provision of extension services on new  crops and a market place were identified.  It was also identified that labour availability in the  family limits the extent of land cultivated and and t hat farm  incomes were affected by t he availability of credit, land  quality, extent a nd size of family labour force.  Using the crop gross margin analysis and labour requirements  for different crops , mod e l farm plans are formulated taking , into  consideration family labour availability (family size) and land  quality constraints, which would give high returns for t he  settlers in the new villages to be established. Finally,  recommendation s for planning to improve the living standards of  the settlers by assisting them to adopt appropriate farming  systems , and for further research are given. 0aLand settlementxThailandxKhao Kho1 aDemaine, Harvey,eChairperson1 aDias, Hiran D., eExamination Committee1 aSetty, E.
