<br/><br/> In  the  past  ten  years,  land  use  and  land  cover  change  was  one  of  the  biggest  concerns  of people because of the direct and immediate effect of this change is not only on economic sector  but  also  on  environment.  Mapping  land  use  and  land  cover  at  bei ng  increasingly across  regions  in  many  scales.  RS  and  GIS  play  an  important  role  in  land  use  and  land cover change detection because of their accuracy and powerfulness. In this study, land use and  land  cover  change  were  detected  using  RS  and  GIS  in  Tam  Non g  district,  Phu  Tho province,  Vietnam.    For  the  purpose,  firstly,  SPOT  image  of  years  2003,  2008  and  2011 were acquired and pre - processed to get coordinate system for all images and better results for  visualization  and  interpretation.    Secondly,  all  the  im ages,  thus  acquired,  were classified  using  supervised  classification  approach,  with  maximum  likelihood  method. Thirdly, classified image results were reclassified using integration method; this work was done  with  the  help  of  other  available  data  and  GIS  so ftware.  Next,  change  detection comparison was done employing pixel by pixel method to identify and extract information of  land  cover  change  in  both  tabulation  and  spatial  form.  Finally,  the  implication  of  the change on agricultural production was evaluated . The result of the study shows that change of land use occurred in different form between the years 2003, 2008 and 2011.  The most striking change was observed in built up land which increased 723.35ha, from 2127.63 ha in  2003  to  2850.98ha  in  2011.  Likewi se,  agriculture  land  suffered  most  from  the  change which  lost  503.37  ha  from  7870.23  ha  between  those  years.  The  study  also  indicates  that the change in land use and land cover, particularly agricultural land, had a slight effect on agricultural productions.
